x86/CET: Fix property note parser [BZ #23467]
GNU_PROPERTY_X86_FEATURE_1_AND may not be the first property item. We
need to check each property item until we reach the end of the property

is is enabled. The second second test fails if IBT isn't enabled

Fix string/tst-xbzero-opt if build with gcc head.
On s390x, the test string/tst-xbzero-opt is failing if build with gcc head:
FAIL: no clear/prepare: expected 32 got 0
FAIL: no clear/test: expected some got 0
FAIL: ordinary clear/prepare: expected 32 got 0
INFO: ordinary clear/test: found 0 patterns (memset not eliminated)
PASS: explicit clear/prepare: expected 32 got 32
PASS: explicit clear/test: expected 0 got 0
In setup_no_clear / setup_ordinary_clear, GCC is omitting the memcpy loop
in prepare_test_buffer. Thus count_test_patterns does not find any of the
test_pattern.
This patch calls use_test_buffer in order to force the compiler to really

the pattern to buf.

Keep expected behaviour for [a-z] and [A-z] (Bug 23393).
In commit 9479b6d5e08eacce06c6ab60abc9b2f4eb8b71e4 we updated all of
the collation data to harmonize with the new version of ISO 14651
which is derived from Unicode 9.0.0. This collation update brought
with it some changes to locales which were not desirable by some
users, in particular it altered the meaning of the
locale-dependent-range regular expression, namely [a-z] and [A-Z], and
for en_US it caused uppercase letters to be matched by [a-z] for the
first time. The matching of uppercase letters by [a-z] is something
which is already known to users of other locales which have this
property, but this change could cause significant problems to en_US
and other similar locales that had never had this change before.
Whether this behaviour is desirable or not is contentious and GNU Awk
has this to say on the topic:
https://www.gnu.org/software/gawk/manual/html_node/Ranges-and-Locales.html
While the POSIX standard also has this further to say: "RE Bracket
Expression":
http://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xbd_chap09.html
"The current standard leaves unspecified the behavior of a range
expression outside the POSIX locale. ... As noted above, efforts were
made to resolve the differences, but no solution has been found that
would be specific enough to allow for portable software while not
invalidating existing implementations."
In glibc we implement the requirement of ISO POSIX-2:1993 and use
collation element order (CEO) to construct the range expression, the
API internally is __collseq_table_lookup(). The fact that we use CEO
and also have 4-level weights on each collation rule means that we can
in practice reorder the collation rules in iso14651_t1_common (the new
data) to provide consistent range expression resolution *and* the
weights should maintain the expected total order. Therefore this
patch does three things:
* Reorder the collation rules for the LATIN script in
iso14651_t1_common to deinterlace uppercase and lowercase letters in
the collation element orders.
* Adds new test data en_US.UTF-8.in for sort-test.sh which exercises
strcoll* and strxfrm* and ensures the ISO 14651 collation remains.
* Add back tests to tst-fnmatch.input and tst-regexloc.c which
exercise that [a-z] does not match A or Z.
The reordering of the ISO 14651 data is done in an entirely mechanical
fashion using the following program attached to the bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=23393#c28
It is up for discussion if the iso14651_t1_common data should be
refined further to have 3 very tight collation element ranges that
include only a-z, A-Z, and 0-9, which would implement the solution
sought after in:
https://sourceware.org/bugzilla/show_bug.cgi?id=23393#c12
and implemented here:
https://www.sourceware.org/ml/libc-alpha/2018-07/msg00854.html
No regressions on x86_64.
Verified that removal of the iso14651_t1_common change causes tst-fnmatch
to regress with:
422: fnmatch ("[a-z]", "A", 0) = 0 (FAIL, expected FNM_NOMATCH) ***
...
425: fnmatch ("[A-Z]", "z", 0) = 0 (FAIL, expected FNM_NOMATCH) ***

x86-64/CET: Extend ucontext_t to save shadow stack
This patch adds a field to ucontext_t to save shadow stack:
1. getcontext and swapcontext are updated to save the caller's shadow
stack pointer and return addresses.
2. setcontext and swapcontext are updated to restore shadow stack and
jump to new context directly.
3. makecontext is updated to allocate a new shadow stack and set the
caller's return address to __start_context.
Since makecontext allocates a new shadow stack when making a new
context and kernel allocates a new shadow stack for clone/fork/vfork
syscalls, we track the current shadow stack base. In setcontext and
swapcontext, if the target shadow stack base is the same as the current
shadow stack base, we unwind the shadow stack. Otherwise it is a stack
switch and we look for a restore token.
We enable shadow stack at run-time only if program and all used shared
objects, including dlopened ones, are shadow stack enabled, which means
that they must be compiled with GCC 8 or above and glibc 2.28 or above.
We need to save and restore shadow stack only if shadow stack is enabled.
When caller of getcontext, setcontext, swapcontext and makecontext is
compiled with smaller ucontext_t, shadow stack won't be enabled at
run-time. We check if shadow stack is enabled before accessing the
extended field in ucontext_t.

x86/CET: Add tests with legacy non-CET shared objects
Check binary compatibility of CET-enabled executables:
1. When CET-enabled executable is used with legacy non-CET shared object
at run-time, ld.so should disable SHSTK and put legacy non-CET shared
objects in legacy bitmap.
2. When IBT-enabled executable dlopens legacy non-CET shared object,
ld.so should put legacy shared object in legacy bitmap.

control how SHSTK is enabled.

x86: Rename __glibc_reserved2 to ssp_base in tcbhead_t
This will be used to record the current shadow stack base for shadow
stack switching by getcontext, makecontext, setcontext and swapcontext.
If the target shadow stack base is the same as the current shadow stack
base, we unwind the shadow stack. Otherwise it is a stack switch and
we look for a restore token to restore the target shadow stack.

nptl: Add C11 threads thrd_* functions
This patch adds the thrd_* definitions from C11 threads (ISO/IEC 9899:2011),
more specifically thrd_create, thrd_curent, rhd_detach, thrd_equal,
thrd_exit, thrd_join, thrd_sleep, thrd_yield, and required types.
Mostly of the definitions are composed based on POSIX conterparts, such as
thrd_t (using pthread_t). For thrd_* function internally direct
POSIX pthread call are used with the exceptions:
1. thrd_start uses pthread_create internal implementation, but changes
how to actually calls the start routine. This is due the difference
in signature between POSIX and C11, where former return a 'void *'
and latter 'int'.
To avoid calling convention issues due 'void *' to int cast, routines
from C11 threads are started slight different than default pthread one.
Explicit cast to expected return are used internally on pthread_create
and the result is stored back to void also with an explicit cast.
2. thrd_sleep uses nanosleep internal direct syscall to avoid clobbering
errno and to handle expected standard return codes. It is a
cancellation entrypoint to be consistent with both thrd_join and
cnd_{timed}wait.
3. thrd_yield also uses internal direct syscall to avoid errno clobbering.
Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu,
arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu,
microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu,
powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu,

Add <bits/indirect-return.h>
Add <bits/indirect-return.h> and include it in <ucontext.h>.
__INDIRECT_RETURN defined in <bits/indirect-return.h> indicates if
swapcontext requires special compiler treatment. The default
__INDIRECT_RETURN is empty.
On x86, when shadow stack is enabled, __INDIRECT_RETURN is defined
with indirect_return attribute, which has been added to GCC 9, to
indicate that swapcontext returns via indirect branch. Otherwise
__INDIRECT_RETURN is defined with returns_twice attribute.
When shadow stack is enabled, remove always_inline attribute from
prepare_test_buffer in string/tst-xbzero-opt.c to avoid:
tst-xbzero-opt.c: In function âprepare_test_bufferâ:
tst-xbzero-opt.c:105:1: error: function âprepare_test_bufferâ can never
be inlined because it uses setjmp
prepare_test_buffer (unsigned char *buf)
when indirect_return attribute isn't available.

x86: Update vfork to pop shadow stack
The shadow stack prevents us from pushing the saved return PC onto
the stack and returning normally. Instead we pop the shadow stack

any stack manipulations done by the vfork'd child doesn't cause the
parent to terminate when CET is enabled.

Avoid insecure usage of tmpnam in tests.
Various glibc testcases use tmpnam in ways subject to race conditions
(generate a temporary file name, then later open that file without
O_EXCL).
This patch fixes those tests to use mkstemp - generally a minimal
local fix to use mkstemp instead of tmpnam, rather than a larger fix
to use other testsuite infrastructure for temporary files. The
unchanged use of tmpnam in posix/wordexp-test.c would fail safe in the
event of a race (it's generating a name for use with mkdir rather than
for a file to be opened for writing).
Tested for x86_64.

i386: Add _CET_ENDBR to indirect jump targets in add_n.S/sub_n.S
i386 add_n.S and sub_n.S use a trick to implment jump tables with LEA.
We can't use conditional branches nor normal jump tables since jump
table entries use EFLAGS set by jump table index. This patch adds
_CET_ENDBR to indirect jump targets and adjust destination for
_CET_ENDBR.

x86: Support IBT and SHSTK in Intel CET [BZ #21598]
Intel Control-flow Enforcement Technology (CET) instructions:
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-en
forcement-technology-preview.pdf
includes Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK).
GNU_PROPERTY_X86_FEATURE_1_IBT is added to GNU program property to
indicate that all executable sections are compatible with IBT when
ENDBR instruction starts each valid target where an indirect branch
instruction can land. Linker sets GNU_PROPERTY_X86_FEATURE_1_IBT on
output only if it is set on all relocatable inputs.
On an IBT capable processor, the following steps should be taken:
1. When loading an executable without an interpreter, enable IBT and
lock IBT if GNU_PROPERTY_X86_FEATURE_1_IBT is set on the executable.
2. When loading an executable with an interpreter, enable IBT if
GNU_PROPERTY_X86_FEATURE_1_IBT is set on the interpreter.
a. If GNU_PROPERTY_X86_FEATURE_1_IBT isn't set on the executable,
disable IBT.
b. Lock IBT.
3. If IBT is enabled, when loading a shared object without
GNU_PROPERTY_X86_FEATURE_1_IBT:
a. If legacy interwork is allowed, then mark all pages in executable
PT_LOAD segments in legacy code page bitmap. Failure of legacy code
page bitmap allocation causes an error.
b. If legacy interwork isn't allowed, it causes an error.
GNU_PROPERTY_X86_FEATURE_1_SHSTK is added to GNU program property to
indicate that all executable sections are compatible with SHSTK where
return address popped from shadow stack always matches return address
popped from normal stack. Linker sets GNU_PROPERTY_X86_FEATURE_1_SHSTK
on output only if it is set on all relocatable inputs.
On a SHSTK capable processor, the following steps should be taken:
1. When loading an executable without an interpreter, enable SHSTK if
GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on the executable.
2. When loading an executable with an interpreter, enable SHSTK if
GNU_PROPERTY_X86_FEATURE_1_SHSTK is set on interpreter.
a. If GNU_PROPERTY_X86_FEATURE_1_SHSTK isn't set on the executable
or any shared objects loaded via the DT_NEEDED tag, disable SHSTK.
b. Otherwise lock SHSTK.
3. After SHSTK is enabled, it is an error to load a shared object
without GNU_PROPERTY_X86_FEATURE_1_SHSTK.
To enable CET support in glibc, --enable-cet is required to configure
glibc. When CET is enabled, both compiler and assembler must support
CET. Otherwise, it is a configure-time error.
To support CET run-time control,
1. _dl_x86_feature_1 is added to the writable ld.so namespace to indicate
if IBT or SHSTK are enabled at run-time. It should be initialized by
init_cpu_features.
2. For dynamic executables:
a. A l_cet field is added to struct link_map to indicate if IBT or
SHSTK is enabled in an ELF module. _dl_process_pt_note or
_rtld_process_pt_note is called to process PT_NOTE segment for
GNU program property and set l_cet.
b. _dl_open_check is added to check IBT and SHSTK compatibilty when
dlopening a shared object.
3. Replace i386 _dl_runtime_resolve and _dl_runtime_profile with
_dl_runtime_resolve_shstk and _dl_runtime_profile_shstk, respectively if
SHSTK is enabled.
CET run-time control can be changed via GLIBC_TUNABLES with
$ export GLIBC_TUNABLES=glibc.tune.x86_shstk=[permissive|on|off]
$ export GLIBC_TUNABLES=glibc.tune.x86_ibt=[permissive|on|off]
1. permissive: SHSTK is disabled when dlopening a legacy ELF module.
2. on: IBT or SHSTK are always enabled, regardless if there are IBT or
SHSTK bits in GNU program property.
3. off: IBT or SHSTK are always disabled, regardless if there are IBT or
SHSTK bits in GNU program property.
<cet.h> from CET-enabled GCC is automatically included by assembly codes
to add GNU_PROPERTY_X86_FEATURE_1_IBT and GNU_PROPERTY_X86_FEATURE_1_SHSTK
to GNU program property. _CET_ENDBR is added at the entrance of all
assembly functions whose address may be taken. _CET_NOTRACK is used to
insert NOTRACK prefix with indirect jump table to support IBT. It is
defined as notrack when _CET_NOTRACK is defined in <cet.h>.

Improve strstr performance
Improve strstr performance. Strstr tends to be slow because it uses
many calls to memchr and a slow byte loop to scan for the next match.
Performance is significantly improved by using strnlen on larger blocks
and using strchr to search for the next matching character. strcasestr
can also use strnlen to scan ahead, and memmem can use memchr to check
for the next match.
On the GLIBC bench tests the performance gains on Cortex-A72 are:
strstr: +25%
strcasestr: +4.3%
memmem: +18%
On a 256KB dataset strstr performance improves by 67%, strcasestr by 47%.

regexec: Fix off-by-one bug in weight comparison [BZ #23036]
Each weight is prefixed by its length, and the length does not include
itself in the count. This can be seen clearly from the find_idx
function in string/strxfrm_l.c, for example. The old code behaved as if
the length itself counted, thus comparing an additional byte after the
weight, leading to spurious comparison failures and incorrect further
partitioning of character equivalence classes.

This is a variant of fgets which fails with ERANGE if the
buffer is too small, and the buffer length is given as an
argument of type size_t.
This function will be useful for implementing NSS file reading
operations. Compared to a direct implementation using the public API,
it avoids an lseek system call in case the line terminator can be
found in the internal read buffer.

aarch64: add HWCAP_ATOMICS to HWCAP_IMPORTANT
This enables searching shared libraries in atomics/ when the hardware
supports LSE atomics of armv8.1 so one can provide optimized variants
of libraries in a portable way.
LSE atomics does not affect library abi, the new instructions can
interoperate with old ones.
I considered the earlier comments on the patch
https://sourceware.org/ml/libc-alpha/2018-04/msg00400.html
https://sourceware.org/ml/libc-alpha/2018-04/msg00625.html
It turns out that the way glibc dynamic linker decides on the search
path is not very flexible: it wants to use hwcap bits and associated
strings. So some targets reuse hwcap bits for glibc internal purposes
to affect the search logic. But hwcap is an interface with the kernel,
glibc should not allocate bits in it for its internal logic as that
limits future hwcap extensions and confusing to users who expect to see
hwcap bits in ifunc resolvers. Instead of rewriting the dynamic linker
path logic (which affects all targets) this patch just uses the existing
mechanism, however this means that the path name has to be the hwcap
name "atomics" and cannot be changed to something more meaningful to
users.
It is hard to tell how much performance benefit this can give, in
principle armv8.1 atomics can be better optimized in the hardware, so it
can make a difference for synchronization heavy code. On some systems
such multilib setup may be the only viable way to get optimized
libraries used.

aarch64: Remove HWCAP_CPUID from HWCAP_IMPORTANT
This partially reverts
commit f82e9672ad89ea1ef40bbe1af71478e255e87c5e
Author: Siddhesh Poyarekar <address@hidden>
aarch64: Allow overriding HWCAP_CPUID feature check using HWCAP_MASK
The idea was to make it possible to disable cpuid based ifunc resolution
in glibc by changing the hwcap mask which the user could already control.
However the hwcap mask has an orthogonal role: it specifies additional
library search paths for the dynamic linker. So "cpuid" got added to
the search paths when it was set in the default mask (HWCAP_IMPORTANT),
which is not useful behaviour, the hwcap masking should not be reused
in the cpu features code.
Meanwhile there is a tunable to set the cpu explicitly so it is possible
to disable the cpuid based dispatch without using a hwcap mask:
GLIBC_TUNABLES=glibc.tune.cpu=generic
* sysdeps/unix/sysv/linux/aarch64/cpu-features.c (init_cpu_features):
Use dl_hwcap without masking.
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.h (HWCAP_IMPORTANT):
Remove HWCAP_CPUID.

libc-abis: Define ABSOLUTE ABI [BZ #19818][BZ #23307]
Define a new ABSOLUTE ABI for static linker's use with EI_ABIVERSION
where correct absolute (SHN_ABS) symbol run-time load semantics is
required. This way it can be ensured at static link time that a program
or DSO will not suffer from previous semantics where absolute symbols
were relocated by the base address, or symbols whose `st_value' is zero
silently ignored leading to a confusing "undefined symbol" error message
at load time, and instead "ELF file ABI version invalid" is printed with
old dynamic loaders, making it clear that there is an ABI version
incompatibility.

locale: XFAIL newlocale usage in static binary (Bug 23164)
There is a glibc optimization which allows for locale categories
to be removed during static compilation. There have been various
bugs for this support over the years, with bug 16915 being the
most recent. The solution there was to emit a reference to all the
categories to avoid any being removed. This fix, although it's in
the generic __nl_langinfo_l function, doesn't appear to be enough
to fix the case for a statically linked program that uses newlocale
and nl_langinfo_l. This commit doesn't fix the problem, but it does
add a XFAIL'd test case such that a fix can be applied against this
and the XFAIL removed. It's not entirely clear that the problem is
the same as that which was seen in bug 16915.

posix: Sync gnulib regex implementation
This patch syncs the regex implementation with gnulib (commit 0ee5212).
Only two changes in GLIBC regex testing are required:
1. posix/bug-regex28.c: as previously discussed [1] the change of
expected results on the pattern should be safe.
2. posix/PCRE.tests: the ERE (a)|\1 is malformed (in the sense that
the \1 doesn't mean anything) and although current GLIBC accepts
it has undefined behavior. This patch removes the specific test.
This sync contains some patches from thread 'Regex: Make libc regex
more usable outside GLIBC.' [2] which have been pushed upstream in
gnulib. This patches also fixes some regex issues (BZ #23233,

ldbl-128ibm-compat: Add printf_size
Since the addition of the _Float128 API, strfromf128 and printf_size use
__printf_fp to print _Float128 values. This is achieved by setting the
'is_binary128' member of the 'printf_info' structure to one. Now that
the format of long double on powerpc64le is getting a third option, this
mechanism is reused for long double values that have binary128 format
(i.e.: when -mabi=ieeelongdouble).
This patch adds __printf_sizeieee128 as an exported symbol, but doesn't
provide redirections from printf_size, yet. All redirections will be
installed in a future commit, once all other functions that print or
read long double values with binary128 format are ready. In
__printf_fp, when 'is_binary128' is one, the floating-point argument is
treated as if it was of _Float128 type, regardless of the value of
'is_long_double', thus __printf_sizeieee128 sets 'is_binary128' to the
same value of 'is_long_double'. Otherwise, double values would not be
printed correctly.
Tested for powerpc64le.

libc: Extend __libc_freeres framework (Bug 23329).
The __libc_freeres framework does not extend to non-libc.so objects.
This causes problems in general for valgrind and mtrace detecting
unfreed objects in both libdl.so and libpthread.so. This change is
a pre-requisite to properly moving the malloc hooks out of malloc
since such a move now requires precise accounting of all allocated
data before destructors are run.
This commit adds a proper hook in libc.so.6 for both libdl.so and
for libpthread.so, this ensures that shm-directory.c which uses
freeit () to free memory is called properly. We also remove the
nptl_freeres hook and fall back to using weak-ref-and-check idiom
for a loaded libpthread.so, thus making this process similar for
all DSOs.
Lastly we follow best practice and use explicit free calls for
both libdl.so and libpthread.so instead of the generic hook process
which has undefined order.
Tested on x86_64 with no regressions.

elf: Accept absolute (SHN_ABS) symbols whose value is zero [BZ #23307]
We have this condition in `check_match' (in elf/dl-lookup.c):
if (__glibc_unlikely ((sym->st_value == 0 /* No value. */
&& stt != STT_TLS)
|| ELF_MACHINE_SYM_NO_MATCH (sym)
|| (type_class & (sym->st_shndx == SHN_UNDEF))))
return NULL;
which causes all !STT_TLS symbols whose value is zero to be silently
ignored in lookup. This may make sense for regular symbols, however not
for absolute (SHN_ABS) ones, where zero is like any value, there's no
special meaning attached to it.
Consequently legitimate programs fail, for example taking the
`elf/tst-absolute-sym' test case, substituting 0 for 0x55aa in
`elf/tst-absolute-sym-lib.lds' and then trying to run the resulting
program we get this:
$ .../elf/tst-absolute-sym
.../elf/tst-absolute-sym: symbol lookup error:
.../elf/tst-absolute-sym-lib.so: undefined symbol: absolute
$
even though the symbol clearly is there:
$ readelf --dyn-syms .../elf/tst-absolute-sym-lib.so | grep '\babsolute\b'
7: 00000000 0 NOTYPE GLOBAL DEFAULT ABS absolute
$
The check for the zero value has been there since forever or commit
d66e34cd4234/08162fa88891 ("Implemented runtime dynamic linker to
support ELF shared libraries.") dating back to May 2nd 1995, and the
problem triggers regardless of commit e7feec374c63 ("elf: Correct

manual: Revise crypt.texi.
This is a major rewrite of the description of 'crypt', 'getentropy',
and 'getrandom'.
A few highlights of the content changes:
- Throughout the manual, public headers, and user-visible messages,
I replaced the term "password" with "passphrase", the term
"password database" with "user database", and the term
"encrypt(ion)" with "(one-way) hashing" whenever it was applied to
passphrases. I didn't bother making this change in internal code
or tests. The use of the term "password" in ruserpass.c survives,
because that refers to a keyword in netrc files, but it is adjusted
to make this clearer.
There is a note in crypt.texi explaining that they were
traditionally called passwords but single words are not good enough
anymore, and a note in users.texi explaining that actual passphrase
hashes are found in a "shadow" database nowadays.
- There is a new short introduction to the "Cryptographic Functions"
section, explaining how we do not intend to be a general-purpose
cryptography library, and cautioning that there _are_, or have
been, legal restrictions on the use of cryptography in many
countries, without getting into any kind of detail that we can't
promise to keep up to date.
- I added more detail about what a "one-way function" is, and why
they are used to obscure passphrases for storage. I removed the
paragraph saying that systems not connected to a network need no
user authentication, because that's a pretty rare situation
nowadays. (It still says "sometimes it is necessary" to
authenticate the user, though.)
- I added documentation for all of the hash functions that glibc
actually supports, but not for the additional hash functions
supported by libxcrypt. If we're going to keep this manual section
around after the transition is more advanced, it would probably
make sense to add them then.
- There is much more detailed discussion of how to generate a salt,
and the failure behavior for crypt is documented. (Returning an
invalid hash on failure is what libxcrypt does; Solar Designer's
notes say that this was done "for compatibility with old programs
that assume crypt can never fail".)
- As far as I can tell, the header 'crypt.h' is entirely a GNU
invention, and never existed on any other Unix lineage. The
function 'crypt', however, was in Issue 1 of the SVID and is now
in the XSI component of POSIX. I tried to make all of the
@standards annotations consistent with this, but I'm not sure I got
them perfectly right.
- The genpass.c example has been improved to use getentropy instead
of the current time to generate the salt, and to use a SHA-256 hash
instead of MD5. It uses more random bytes than is strictly
necessary because I didn't want to complicate the code with proper
base64 encoding.
- The testpass.c example has three hardwired hashes now, to
demonstrate that different one-way functions produce different
hashes for the same input. It also demonstrates how DES hashing
only pays attention to the first eight characters of the input.
- There is new text explaining in more detail how a CSPRNG differs
from a regular random number generator, and how
getentropy/getrandom are not exactly a CSPRNG. I tried not to make
specific falsifiable claims here. I also tried to make the
blocking/cancellation/error behavior of both getentropy and
getrandom clearer.

manual: Reorganize crypt.texi.
In preparation for a major revision of the documentation for
crypt(_r), getentropy, and getrandom, reorganize crypt.texi. This
patch does not change any text; it only deletes and moves text.
The description of 'getpass' moves to terminal.texi, since all it does
is read a password from the controlling terminal with echo disabled.
The "Legal Problems" section of crypt.texi is dropped, and the
introductory text is shifted down to the "Encrypting Passwords"
section; the next patch will add some new introductory text.
Also, it is no longer true that crypt.texi's top @node needs to have
no pointers. That was a vestige of crypt/ being an add-on. (makeinfo
itself doesn't need @node pointers anymore, but the scripts that
assemble the libc manual's topmost node rely on each chapter-level
node having them.)

Disallow use of DES encryption functions in new programs.
The functions encrypt, setkey, encrypt_r, setkey_r, cbc_crypt,
ecb_crypt, and des_setparity should not be used in new programs,
because they use the DES block cipher, which is unacceptably weak by
modern standards. Demote all of them to compatibility symbols, and
remove their prototypes from installed headers. cbc_crypt, ecb_crypt,
and des_setparity were already compat symbols when glibc was
configured with --disable-obsolete-rpc.
POSIX requires encrypt and setkey to be available when _XOPEN_CRYPT
is defined, so this change also removes the definition of X_OPEN_CRYPT
from <unistd.h>.
The entire "DES Encryption" section is dropped from the manual, as is
the mention of AUTH_DES and FIPS 140-2 in the introduction to
crypt.texi. The documentation of 'memfrob' cross-referenced the DES
Encryption section, which is replaced by a hyperlink to libgcrypt, and
while I was in there I spruced up the actual documentation of
'memfrob' and 'strfry' a little. It's still fairly jokey, because
those functions _are_ jokes, but they do also have real use cases, so
people trying to use them for real should have all the information
they need.
DES-based authentication for Sun RPC is also insecure and should be
deprecated or even removed, but maybe that can be left as TI-RPC's
problem.

getifaddrs: Don't return ifa entries with NULL names [BZ #21812]
A lookup operation in map_newlink could turn into an insert because of
holes in the interface part of the map. This leads to incorrectly set
the name of the interface to NULL when the interface is not present
for the address being processed (most likely because the interface was
added between the RTM_GETLINK and RTM_GETADDR calls to the kernel).
When such changes are detected by the kernel, it'll mark the dump as
"inconsistent" by setting NLM_F_DUMP_INTR flag on the next netlink
message.
This patch checks this condition and retries the whole operation.
Hopes are that next time the interface corresponding to the address
entry is present in the list and correct name is returned.

Fix hardcoded /tmp paths in testing (bug 13888).
As noted in bug 13888, and as I noted previously in
<https://sourceware.org/ml/libc-alpha/2000-10/msg00111.html>, various
tests used hardcoded paths in /tmp, so posing issues for simultaneous
test runs from different build directories.
This patch fixes such uses of hardcoded file names to put them in the
build directory instead (in the case of stdio-common/bug5 the file
names are changed as well, to avoid a conflict with the name bug5.out
also used for the automatic test output redirection). It also fixes
test-installation.pl likewise (that was using filenames with $$ in
them rather than strictly hardcoded names, but that's still not good
practice for temporary file naming).
Note that my list of files changed is not identical to that in bug
13888. I added tst-spawn3.c and test-installation.pl, and removed
some tests that seem to me (now) to create temporary files securely
(simply using /tmp is not itself a problem if the temporary files are
handled properly with mkstemp; I haven't checked whether those tests
used to do things insecurely). conformtest is not changed because the
makefiles always pass a --tmpdir option so the /tmp default is
irrelevant, and for the same reason there is no actual problem with
nptl/tst-umask1.c because again the makefiles always override the
default.
nptl/sockperf.c is ignored because there is no code to run it;
probably that file should actually be removed.
Some tests use the mktemp function, but I think they all use it in a
way that *is* secure (for generating names for directories / sockets /
fifos / symlinks, where the operation using the name will not follow
symlinks and so there is no potential for a symlink attack on the
account running the testsuite).
Some tests use the tmpnam function to generate temporary file names.
This is in principle insecure, but not addressed by this patch (I
consider it a separate issue from the fully hardcoded paths).
Tested for x86_64.

Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)
This patch fixes the OFD ("file private") locks for architectures that
support non-LFS flock definition (__USE_FILE_OFFSET64 not defined). The
issue in this case is both F_OFD_{GETLK,SETLK,SETLKW} and
F_{SET,GET}L{W}K64 expects a flock64 argument and when using old
F_OFD_* flags with a non LFS flock argument the kernel might interpret
the underlying data wrongly. Kernel idea originally was to avoid using
such flags in non-LFS syscall, but since GLIBC uses fcntl with LFS
semantic as default it is possible to provide the functionality and
avoid the bogus struct kernel passing by adjusting the struct manually
for the required flags.
The idea follows other LFS interfaces that provide two symbols:
1. A new LFS fcntl64 is added on default ABI with the usual macros to
select it for FILE_OFFSET_BITS=64.
2. The Linux non-LFS fcntl use a stack allocated struct flock64 for
F_OFD_{GETLK,SETLK,SETLKW} copy the results on the user provided
struct.
3. Keep a compat symbol with old broken semantic for architectures
that do not define __OFF_T_MATCHES_OFF64_T.
So for architectures which defines __USE_FILE_OFFSET64, fcntl64 will
aliased to fcntl and no adjustment would be required. So to actually
use F_OFD_* with LFS support the source must be built with LFS support
(_FILE_OFFSET_BITS=64).
Also F_OFD_SETLKW command is handled a cancellation point, as for
F_SETLKW{64}.
Checked on x86_64-linux-gnu and i686-linux-gnu.

nscd: Use struct scratch_buffer, not extend_alloca in most caches [BZ
#18023]
This replaces the ERANGE retry loops with loops which have heap
fallback. Heap allocation might actually be required for extremely
large NSS results.

nscd restart: Use malloc instead of extend_alloca [BZ #18023]
This introduces a separate function, read_cmdline, which reads the

m68k: Reorganize log1p and significand implementations
Commit 5e79e0292bfb03f40e43379fd92581ad8eae9cb8 broke m68k after
s_significand.c became available in the build directory. All m68k
implementations of log1p and significand were including s_significand.c
and stopped working after the inclusion of the the auto-generated file.
This patch reorganizes the implementation of log1p and significand for
m680x0 in order to avoid hitting this problem.
* sysdeps/m68k/m680x0/fpu/s_log1p.c: Set as the generic file for
all log1p and significand functions on m680x0.

of s_significand.c..

bug-strspn1.c:14:3: error: right-hand operand of comma expression has no

strspn (b++, "");
^~~~~~~~~~~~~~~~
and a similar error for bug-strpbrk1.c. I'm not sure what GCC change
introduced this, and the wording of the message is a bit off (in the
source it's not a comma expression, that must reflect GCC's IR). But
the warning is correct (strspn is a pure function, the call is
useless, and if there wasn't an argument with a side effect much older
GCC would have warned); the point of the test is to verify that the
side effect in an argument still occurs for this useless call that can
otherwise be optimized to an (unused) constant (testing for a bug
there once was in an old strspn macro). This patch duly arranges for
the warning to be disabled for this code.
Tested with build-many-glibcs.py for aarch64-linux-gnu.

Fix scanf rounding of negative floating-point numbers (bug 23280).
As reported in bug 23280, scanf functions produce incorrectly rounded
result for floating-point formats in FE_UPWARD and FE_DOWNWARD modes,
because they pass the input with sign removed to strtod functions, and
then negate the result if there was a '-' at the start of the input.
This patch fixes this by arranging for the sign to be passed to strtod
rather than scanf doing the negation itself. In turn, keeping the
sign around in the buffer being built up for strtod requires updating
places that examine char_buffer_size (&charbuf) to allow for the sign
being there as an extra character.
Tested for x86_64.

Ignore -Wrestrict for one strncat test.
With current GCC mainline, one strncat test involving a size close to
SIZE_MAX results in a -Wrestrict warning that that buffer size would
imply that the two buffers must overlap. This patch fixes the build
by adding disabling of -Wrestrict (for GCC versions supporting that
option) to the already-present disabling of -Wstringop-overflow= and
-Warray-bounds for this test.
Tested with build-many-glibcs.py that this restores the testsuite
build with GCC mainline for aarch64-linux-gnu.

aarch64: Use an ifunc/VDSO to implement gettimeofday in shared glibc.
This patch uses an ifunc to implement gettimeofday in the shared libc.
This is faster compared to the vsyscall mechanism that has to check a
global pointer, demangle it and call it indirectly when the VDSO is
present. Resolving the gettimeofday symbol directly to the VDSO code
is safe because there are no failures that the libc has to handle by
setting errno like in a generic vsyscall (the only failure when the
VDSO code falls back to a syscall is EFAULT, but passing an invalid
pointer is undefined behaviour so returning -EFAULT is fine).
If the kernel supports the VDSO interface we use it for extern calls,
otherwise the old vsyscall method is used which falls back to a syscall.
The static version of gettimeofday continues to use a syscall, libc.so
internal calls use the old vsyscall method.

Fix strtod overflow detection (bug 23279).
As shown by bug 23279, strtod's round_and_return has an off-by-one
error in its overflow detection, only counting an exponent greater
than MAX_EXP as overflowing when an exponent of MAX_EXP also means
overflow (recall the ISO C definition of DBL_MAX_EXP etc. is based on
a floating-point model where 2^exp is multiplied by a value in the
interval [0.5, 1), so 2^MAX_EXP is not representable).
For decimal arguments to strtod, a separate overflow check in the main
implementation covers the case where the integer part of the argument
(truncated to the nearest integer towards zero) has more than MAX_EXP
bits, meaning that this issue in round_and_return only affects cases
(arguments with absolute value strictly between the maximum
representable value and 2^MAX_EXP) where overflow depends on the
rounding mode; in such cases, the returned value would still have been
correct on overflow but without the overflow exception being raised or
errno being set to ERANGE. For hex float arguments, however, other
cases can arise, as shown in bug 23279, where a value with exponent
already set to MAX_EXP is passed into round_and_return and a result
can wrongly end up being NaN, or infinity instead of the largest
finite value.
This patch fixes the off-by-one error, adds testing of overflow
exceptions to the tst-strtod-round framework, and adds tests of these
issues.
Tested for x86_64. Also ran the tst-strtod-round tests for powerpc to
make sure the new tests didn't introduce any new failures for IBM long
double.

Do not use const attribute for nan functions (bug 23277).
As in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86113 for
__builtin_nan, bits/mathcalls.h wrongly declares the nan function with
the __const__ attribute. Because the function reads memory pointed to
by an argument, it's only pure, not const. This patch removes the
incorrect attribute and adds a testcase for the bug. No __pure__
attribute is added to replace the incorrect __const__ one, since that
would introduce problems when using GCC versions that have the
incorrect built-in __const__ attribute and warn for the combination of
those two attributes.
Tested for x86_64.

Improve DST handling (Bug 23102, Bug 21942, Bug 18018, Bug 23259).
This commit improves DST handling significantly in the following
ways: firstly is_dst () is overhauled to correctly process DST
sequences that would be accepted given the ELF gABI. This means that
we actually now accept slightly more sequences than before. Now we
accept $ORIGIN$ORIGIN, but in the past we accepted only $ORIGIN\0 or
$ORIGIN/..., but this kind of behaviour results in unexpected
and uninterpreted DST sequences being used as literal search paths
leading to security defects. Therefore the first step in correcting
this defect is making is_dst () properly account for all DSTs
and making the function context free in the sense that it counts
DSTs without knowledge of path, or AT_SECURE. Next, _dl_dst_count ()
is also simplified to count all DSTs regardless of context.
Then in _dl_dst_substitute () we reintroduce context-dependent
processing for such things as AT_SECURE handling. At the level of
_dl_dst_substitute we can have access to things like the true start
of the string sequence to validate $ORIGIN-based paths rooted in
trusted directories. Lastly, we tighten up the accepted sequences
in AT_SECURE, and avoid leaving known unexpanded DSTs, this is
noted in the NEWS entry.
Verified with a sequence of 68 tests on x86_64 that cover
non-AT_SECURE and AT_SECURE testing using a sysroot (requires root
to run). The tests cover cases for bug 23102, bug 21942, bug 18018,
and bug 23259. These tests are not yet appropriate for the glibc
regression testsuite, but with the upcoming test-in-container testing
framework it should be possible to include these tests upstream soon.

Avoid cancellable I/O primitives in ld.so.
Neither the <dlfcn.h> entry points, nor lazy symbol resolution, nor
initial shared library load-up, are cancellation points, so ld.so
should exclusively use I/O primitives that are not cancellable. We
currently achieve this by having the cancellation hooks compile as
no-ops when IS_IN(rtld); this patch changes to using exclusively
_nocancel primitives in the source code instead, which makes the
intent clearer and significantly reduces the amount of code compiled
under IS_IN(rtld) as well as IS_IN(libc) -- in particular,
elf/Makefile no longer thinks we require a copy of unwind.c in
rtld-libc.a. (The older mechanism is preserved as a backstop.)
The bulk of the change is splitting up the files that define the
_nocancel I/O functions, so they don't also define the variants that
*are* cancellation points; after which, the existing logic for picking
out the bits of libc that need to be recompiled as part of ld.so Just
Works. I did this for all of the _nocancel functions, not just the
ones used by ld.so, for consistency.
fcntl was a little tricky because it's only a cancellation point for
certain opcodes (F_SETLKW(64), which can block), and the existing
__fcntl_nocancel wasn't applying the FCNTL_ADJUST_CMD hook, which
strikes me as asking for trouble, especially as the only nontrivial
definition of FCNTL_ADJUST_CMD (for powerpc64) changes F_*LK* opcodes.
To fix this, fcntl_common moves to fcntl_nocancel.c along with
__fcntl_nocancel, and changes its name to the extern (but hidden)
symbol __fcntl_nocancel_adjusted, so that regular fcntl can continue
calling it. __fcntl_nocancel now applies FCNTL_ADJUST_CMD; so that
both both fcntl.c and fcntl_nocancel.c can see it, the only nontrivial
definition moves from sysdeps/u/s/l/powerpc/powerpc64/fcntl.c to
.../powerpc64/sysdep.h and becomes entirely a macro, instead of a macro
that calls an inline function.
The nptl version of libpthread also changes a little, because its
"compat-routines" formerly included files that defined all the
_nocancel functions it uses; instead of continuing to duplicate them,
I exported the relevant ones from libc.so as GLIBC_PRIVATE. Since the
Linux fcntl.c calls a function defined by fcntl_nocancel.c, it can no
longer be used from libpthread.so; instead, introduce a custom
forwarder, pt-fcntl.c, and export __libc_fcntl from libc.so as
GLIBC_PRIVATE. The nios2-linux ABI doesn't include a copy of vfork()
in libpthread, and it was handling that by manipulating
libpthread-routines in .../linux/nios2/Makefile; it is cleaner to do
what other such ports do, and have a pt-vfork.S that defines no symbols.
Right now, it appears that Hurd does not implement _nocancel I/O, so
sysdeps/generic/not-cancel.h will forward everything back to the
regular functions. This changed the names of some of the functions
that sysdeps/mach/hurd/dl-sysdep.c needs to interpose.

ended up with no definition of the strncmp symbol at all: The
implementations were renamed for use within an IFUNC resolver, but the
IFUNC resolver itself was missing (because rtld does not use IFUNCs).

Fix ldbl-96 fma (Inf, Inf, finite) (bug 23272).
As reported in bug 23272, the ldbl-96 implementation of fma (fma for
double, in terms of ldbl-96 as the internal arithmetic type, as used
on 32-bit x86) is missing some of the special-case handling for
non-finite arguments, resulting in incorrect NaN results when the
first two arguments are infinities, the third is finite and so the
infinities go through the logic for finite arguments. This patch
fixes it by handling all cases of non-finite arguments up front, with
additional fma tests for the problem cases being added to the
testsuite.
Tested for x86_64 and x86.

posix: Fix posix_spawnp to not execute invalid binaries in non compat mode
(BZ#23264)
Current posix_spawnp implementation wrongly tries to execute invalid
binaries (for instance script without shebang) as a shell script in
non compat mode. It was a regression introduced by
9ff72da471a509a8c19791efe469f47fa6977410 when __spawni started to use
__execvpe instead of __execve (glibc __execvpe try to execute ENOEXEC
as shell script regardless).
This patch fixes it by using an internal symbol (__execvpex) with the
faulty semantic (since compat mode is handled by spawni.c itself).
It was reported by Daniel Drake on libc-help [1].
Checked on x86_64-linux-gnu and i686-linux-gnu.

powerpc64le: Fix TFtype in sqrtf128 when using -mabi=ieeelongdouble
When building with -mlong-double-128 or -mabi=ibmlongdouble, TFtype
represents the IBM 128-bit extended floating point type, while KFtype
represents the IEEE 128-bit floating point type.
The soft float implementation of e_sqrtf128 had to redefine TFtype and
TF in order to workaround this issue. However, this behavior changes
when -mabi=ieeelongdouble is used and the macros are not necessary.

x86-64: Optimize strcmp/wcscmp and strncmp/wcsncmp with AVX2
Optimize x86-64 strcmp/wcscmp and strncmp/wcsncmp with AVX2. It uses vector
comparison as much as possible. Peak performance observed on a SkyLake
machine: 9x, 3x, 2.5x and 5.5x for strcmp, strncmp, wcscmp and wcsncmp,
respectively. The larger the comparison length, the more benefit using
avx2 functions, except on the strcmp, where peak is observed at length
== 32 bytes. Select AVX2 strcmp/wcscmp on AVX2 machines where vzeroupper
is preferred and AVX unaligned load is fast.
NB: It uses TZCNT instead of BSF since TZCNT produces the same result
as BSF for non-zero input. TZCNT is faster than BSF and is executed
as BSF if machine doesn't support TZCNT.

Make powerpc-nofpu __sqrtsf2, __sqrtdf2 compat symbols (bug 18473).
powerpc-nofpu libc exports __sqrtsf2 and __sqrtdf2 symbols. The
export of these soft-fp symbols is a mistake; they aren't part of the
libgcc interface and GCC will never generate code that calls them.
This patch makes them into compat symbols (no code built for static
libc), moving their sources from the generic soft-fp sources to
sysdeps/powerpc/nofpu (the underlying soft-fp FP_SQRT functionality
remains of use to implement actual sqrt public interfaces, such as
sqrtl / sqrtf128 for which it is used on various platforms, but
__sqrt[sdt]f2 are not such interfaces).
Tested with build-many-glibcs.py for relevant platforms.

libio: Avoid _allocate_buffer, _free_buffer function pointers [BZ #23236]
These unmangled function pointers reside on the heap and could
be targeted by exploit writers, effectively bypassing libio vtable
validation. Instead, we ignore these pointers and always call
malloc or free.
In theory, this is a backwards-incompatible change, but using the
global heap instead of the user-supplied callback functions should
have little application impact. (The old libstdc++ implementation
exposed this functionality via a public, undocumented constructor
in its strstreambuf class.)

Remove sysdeps/sparc/sparc64/soft-fp directory.
As per <https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>,
there should not be separate sysdeps/<arch>/soft-fp directories when
those are used by all configurations that use sysdeps/<arch>, and,
more generally, should not be sysdeps/foo/Implies files pointing to a
subdirectory foo/bar. This patch eliminates the
sysdeps/sparc/sparc64/soft-fp directory accordingly, merging its
contents into sysdeps/sparc/sparc64. This completes removing the
unnecessary <arch>/soft-fp sysdeps directories.
sysdeps/sparc/sparc64/soft-fp/e_ilogbl.c is removed rather than moved.
It was not in fact used previously - the ldbl-128 version of
e_ilogbl.c was used instead - and moving it into sysdeps/sparc/sparc64
results in it being used, but causing a build failure because of
FP_DECL_EX declaring an unused variable (as I noted in
<https://sourceware.org/ml/libc-alpha/2013-10/msg00457.html> that file
doesn't appear to use FP_DECL_EX). Given that the file was previously
unused and so presumably not tested recently, removing it is the safe
way to avoid this patch changing what actually gets built into glibc
(if this file should turn out more efficient than the ldbl-128
e_ilogbl.c, it can always be added back in future with the build
failure fixed).
Tested with build-many-glibcs.py that installed stripped shared
libraries for sparc configurations are unchanged by this patch.

powerpc: Move around math-related Implies
Currently, powerpc, powerpc64, and powerpc64le imply the same set of
subdirectories from sysdeps/ieee754: flt-32, dbl-64, ldbl-128ibm, and
ldbl-opt. In preparation for the transition of the long double format -
from IBM Extended Precision to IEEE 754 128-bits floating-point - on
powerpc64le, this patch splits the shared Implies file into three
separate files (one for each of the powerpc architectures), without
changing their contents. Future patches will modify powerpc64le.
* sysdeps/powerpc/Implies: Removed. Previous contents copied to...
* sysdeps/powerpc/powerpc32/Implies-after: ... here.
* sysdeps/powerpc/powerpc64/be/Implies-after: ... here.
* sysdeps/powerpc/powerpc64/le/Implies-before: ... and here.

there should not be separate sysdeps/<arch>/soft-fp directories when
those are used by all configurations that use sysdeps/<arch>, and,
more generally, should not be sysdeps/foo/Implies files pointing to a
subdirectory foo/bar.
sysdeps/powerpc/soft-fp isn't quite such a case, as the Implies files
pointing to it are
sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/Implies and
sysdeps/unix/sysv/linux/powerpc/powerpc32/e500/nofpu/Implies (and
indeed there is a different sfp-machine.h used for powerpc64le).
However, the same principle applies: there is no need for this
directory because sfp-machine.h, the only file in it, can most
naturally go in sysdeps/powerpc/nofpu, which is used by exactly the
same configurations (and there is a close dependence between the files
there and the sfp-machine.h implementation). This patch eliminates
the sysdeps/powerpc/soft-fp directory accordingly.
Tested with build-many-glibcs.py that installed stripped shared
libraries for powerpc configurations are unchanged by this patch.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/Implies: Remove
powerpc/soft-fp.

Likewise.

Fix i686-linux-gnu build with GCC mainline.
Building with recent GCC mainline for i686-linux-gnu is failing with:
../sysdeps/ieee754/flt-32/k_rem_pio2f.c: In function '__kernel_rem_pio2f':
../sysdeps/ieee754/flt-32/k_rem_pio2f.c:186:28: error: 'fq[0]' may be used
uninitialized in this function [-Werror=maybe-uninitialized]
fv = math_narrow_eval (fq[0]-fv);
^
and
../sysdeps/ieee754/dbl-64/k_rem_pio2.c: In function '__kernel_rem_pio2':
../sysdeps/ieee754/dbl-64/k_rem_pio2.c:333:32: error: 'fq[0]' may be used
uninitialized in this function [-Werror=maybe-uninitialized]
fv = math_narrow_eval (fq[0] - fv);
^
These are similar to -Warray-bounds cases for which the DIAG_* macros
are already used in those files: the array element is in fact always
initialized, but the reasoning that it is depends on another array not
having been all zero at an earlier point, which depends on the
functions not being called with zero arguments. Thus, this patch uses
DIAG_* to disable -Wmaybe-uninitialized for this code.
(The warning may be i686-specific because of math_narrow_eval somehow
perturbing what the compiler does with this code enough to cause the
warning. I don't know why it doesn't appear for i686-gnu.)
Tested with build-many-glibcs.py that this fixes the i686 build in
this configuration.
* sysdeps/ieee754/dbl-64/k_rem_pio2.c (__kernel_rem_pio2): Ignore
-Wmaybe-uninitialized around access to fq[0].
* sysdeps/ieee754/flt-32/k_rem_pio2f.c (__kernel_rem_pio2f):
Likewise.

Make llseek a compat symbol (bug 18471).
The llseek function name is an obsolete, Linux-specific, unprototyped
name for lseek64 with a link-time warning. This patch completes the
obsoletion of this function name by making it into a compat symbol,
not available for newly linked programs and not included in the ABI
for new ports.
When a compat symbol is defined in syscalls.list, the code for that
function is not built at all for static linking unless some non-compat
symbol for that function is also defined with an explicit symbol
version, so an explicit symbol version for lseek64 is added to the
MIPS n32 syscalls.list. The case in make-syscalls.sh that handles
such explicit non-compat symbol versions then needs to be changed to
use weak_alias instead of strong_alias when the syscall is built
outside of libc, to avoid linknamespace failures from a strong lseek64
symbol in static libpthread.
The x32 llseek.S was as far as I could tell already unused (nothing
builds an llseek.* source file, at least since the lseek / lseek64 /
llseek consolidation), so is removed in this patch as well.

Split test-tgmath3 by function.
It has been noted that test-tgmath3 is slow to compile, and to link on
some systems
<https://sourceware.org/ml/libc-alpha/2018-02/msg00477.html>, because
of the size of the test.
I'm working on tgmath.h support for the TS 18661-1 / 18661-3 functions
that round their results to a narrower type. For the functions
already present in glibc, this wouldn't make test-tgmath3 much bigger,
because those functions only have two arguments. For the narrowing
versions of fma (for which I've not yet added the functions to glibc),
however, it would result in many configurations building tests of the
type-generic macros f32fma, f64fma, f32xfma, f64xfma, each with 21
possible types for each of three arguments (float, double, long double
aren't valid argument types for these macros when they return a
_FloatN / _FloatNx type), so substantially increasing the size of the
testcase.
To avoid further increasing the size of a single test when adding the
type-generic narrowing fma macros, this patch arranges for the
test-tgmath3 tests to be run separately for each function tested. The
fma tests are still by far the largest (next is pow, as that has two
arguments that can be real or complex; after that, the two-argument
real-only functions), but each type-generic fma macro for a different
return type would end up with its tests being run separately, rather
than increasing the size of a single test.
To avoid accidentally missing testing a macro because
gen-tgmath-tests.py supports testing it but the makefile fails to call
it for that function, a test is also added that verifies that the
lists of macros in the makefile and gen-tgmath-tests.py agree.
Tested for x86_64.
* math/gen-tgmath-tests.py: Import sys.
(Tests.__init__): Initialize macros_seen.
(Tests.add_tests): Add macro to macros_seen. Only generate tests
if requested to do so for this macro.

Obsolete nfsservctl.
The Linux nfsservctl syscall was removed in Linux 3.1. Since the
minimum kernel version for use with glibc is 3.2, the glibc wrapper
for this syscall can no longer usefully be called. This patch makes
it into a compat symbol, not provided at all for static linking or new
ports. (It was already the case that there was no header declaration
of this function.)
Tested for x86_64.

Fix year 2039 bug for localtime with 64-bit time_t (bug 22639).
Bug 22639 reports localtime failing to handle time offset transitions
correctly in 2039 and later on platforms with 64-bit time_t.
The problem is the use of SECSPERDAY (constant 86400) in calculations
such as
t = ((year - 1970) * 365
+ /* Compute the number of leapdays between 1970 and YEAR
(exclusive). There is a leapday every 4th year ... */
+ ((year - 1) / 4 - 1970 / 4)
/* ... except every 100th year ... */
- ((year - 1) / 100 - 1970 / 100)
/* ... but still every 400th year. */
+ ((year - 1) / 400 - 1970 / 400)) * SECSPERDAY;
where t is of type time_t and year is of type int. Before my commit
92bd70fb85bce57ac47ba5d8af008736832c955a (an update from tzcode,
included in 2.26 and later releases), SECSPERDAY was obtained from a
file imported from tzcode, where the value included a cast to
int_fast32_t. On 64-bit platforms, glibc defines int_fast32_t to be
long int, so 64-bit, but my patch resulted in it changing to int.
(The bug would probably have existed even before my patch for x32,
which has 64-bit time_t but 32-bit int_fast32_t, but I haven't
verified that.)
This patch fixes the problem by including a cast to time_t in the
definition of SECSPERDAY. (64-bit time support for 32-bit systems
should move such code that isn't a public interface to using the
internal 64-bit version of time_t throughout.)
Tested for x86_64 and x86.

* time/tzset.c (SECSPERDAY): Cast to time_t.
* time/tst-y2039.c: New file.
* time/Makefile (tests): Add tst-y2039.

Add narrowing divide functions.
This patch adds the narrowing divide functions from TS 18661-1 to
glibc's libm: fdiv, fdivl, ddivl, f32divf64, f32divf32x, f32xdivf64

Fix concurrent changes on nscd aware files (BZ #23178)
As indicated by BZ#23178, concurrent access on some files read by nscd
may result non expected data send through service requisition. This is
due 'sendfile' Linux implementation where for sockets with zero-copy
support, callers must ensure the transferred portions of the the file
reffered by input file descriptor remain unmodified until the reader
on the other end of socket has consumed the transferred data.
I could not find any explicit documentation stating this behaviour on
Linux kernel documentation. However man-pages sendfile entry [1] states
in NOTES the aforementioned remark. It was initially pushed on man-pages
with an explicit testcase [2] that shows changing the file used in
'sendfile' call prior the socket input data consumption results in
previous data being lost.
From commit message it stated on tested Linux version (3.15) only TCP
socket showed this issues, however on recent kernels (4.4) I noticed the
same behaviour for local sockets as well.
Since sendfile on HURD is a read/write operation and the underlying
issue on Linux, the straightforward fix is just remove sendfile use
altogether. I am really skeptical it is hitting some hotstop (there
are indication over internet that sendfile is helpfull only for large
files, more than 10kb) here to justify that extra code complexity or
to pursuit other possible fix (through memory or file locks for
instance, which I am not sure it is doable).
Checked on x86_64-linux-gnu.

Add narrowing multiply functions.
This patch adds the narrowing multiply functions from TS 18661-1 to
glibc's libm: fmul, fmull, dmull, f32mulf64, f32mulf32x, f32xmulf64
for all configurations; f32mulf64x, f32mulf128, f64mulf64x,
f64mulf128, f32xmulf64x, f32xmulf128, f64xmulf128 for configurations
with _Float64x and _Float128; __nldbl_dmull for ldbl-opt.
The changes are mostly essentially the same as for the narrowing add
functions, so the description of those generally applies to this patch
as well. f32xmulf64 for i386 cannot use precision control as used for
add and subtract, because that would result in double rounding for
subnormal results, so that uses round-to-odd with long double
intermediate result instead. The soft-fp support involves adding a
new FP_TRUNC_COOKED since soft-fp multiplication uses cooked inputs
and outputs.
Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft
float) and powerpc, and with build-many-glibcs.py.

powerpc: Fix the compiler type used with C++ when -mabi=ieeelongdouble
When compiling C++ code with -mabi=ieeelongdouble, KCtype is
unavailable and the long double type should be used instead.
This is also providing macro __HAVE_FLOAT128_UNLIKE_LDBL in order to
identify the kind of long double type is being used in the current
compilation unit.
Notice that bits/floatn.h cannot benefit from the new macro due to order
of header inclusion.
* bits/floatn-common.h: Define __HAVE_FLOAT128_UNLIKE_LDBL.
* math/math.h: Restrict the prototype definition for the functions
issignaling(_Float128) and iszero(_Float128); and template
__iseqsig_type<_Float128>, from __HAVE_DISTINCT_FLOAT128 to

&& __LDBL_MANT_DIG__ == 113]: Use long double suffix for
__f128() constants; define the type _Float128 as long double;
and reuse long double in __CFLOAT128.

Do not include math-barriers.h in math_private.h.
This patch continues the math_private.h cleanup by stopping
math_private.h from including math-barriers.h and making the users of
the barrier macros include the latter header directly. No attempt is
made to remove any math_private.h includes that are now unused, except
in strtod_l.c where that is done to avoid line number changes in
assertions, so that installed stripped shared libraries can be
compared before and after the patch. (I think the floating-point
environment support in math_private.h should also move out - some
architectures already have fenv_private.h as an architecture-internal
header included from their math_private.h - and after moving that out
might be a better time to identify unused math_private.h includes.)
Tested for x86_64 and x86, and tested with build-many-glibcs.py that
installed stripped shared libraries are unchanged by the patch.

aarch64,falkor: Ignore prefetcher tagging for smaller copies
For smaller and medium sized copies, the effect of hardware
prefetching are not as dominant as instruction level parallelism.
Hence it makes more sense to load data into multiple registers than to
try and route them to the same prefetch unit. This is also the case
for the loop exit where we are unable to latch on to the same prefetch
unit anyway so it makes more sense to have data loaded in parallel.
The performance results are a bit mixed with memcpy-random, with
numbers jumping between -1% and +3%, i.e. the numbers don't seem
repeatable. memcpy-walk sees a 70% improvement (i.e. > 2x) for 128
bytes and that improvement reduces down as the impact of the tail copy
decreases in comparison to the loop.
* sysdeps/aarch64/multiarch/memcpy_falkor.S (__memcpy_falkor):
Use multiple registers to copy data in loop tail.

aarch64,falkor: Ignore prefetcher hints for memmove tail
The tail of the copy loops are unable to train the falkor hardware
prefetcher because they load from a different base compared to the hot
loop. In this case avoid serializing the instructions by loading them
into different registers. Also peel the last iteration of the loop
into the tail (and have them use different registers) since it gives
better performance for medium sizes.
This results in performance improvements of between 3% and 20% over
the current falkor implementation for sizes between 128 bytes and 1K
on the memmove-walk benchmark, thus mostly covering the regressions
seen against the generic memmove.

Move math_check_force_underflow macros to separate math-underflow.h.
This patch continues cleaning up math_private.h by moving the
math_check_force_underflow set of macros to a separate header
math-underflow.h.
This header is included by the files that need it rather than from
math_private.h. Moving these macros to a separate file removes the
math_private.h uses of macros from float.h, so the inclusion of
float.h in math_private.h is also removed; files that were depending
on that inclusion are fixed to include float.h directly. The
inclusion of math-barriers.h from math_private.h will be removed in a
separate patch.
Tested for x86_64 and x86. Also tested with build-many-glibcs.py that
installed stripped shared libraries are unchanged by this patch.

Move math_opt_barrier, math_force_eval to separate math-barriers.h.
This patch continues cleaning up math_private.h by moving the
math_opt_barrier and math_force_eval macros to a separate header
math-barriers.h.
At present, those macros are inside a "#ifndef math_opt_barrier" in
math_private.h to allow architectures to override them and then use
a separate math-barriers.h header, no such #ifndef or #include_next is
needed; architectures just have their own alternative version of
math-barriers.h when providing their own optimized versions that avoid
going through memory unnecessarily. The generic math-barriers.h has a
comment added to document these two macros.
In this patch, math_private.h is made to #include <math-barriers.h>,
so files using these macros do not need updating yet. That is because
of uses of math_force_eval in math_check_force_underflow and
math_check_force_underflow_nonneg, which are still defined in
math_private.h. Once those are moved out to a separate header, that
separate header can be made to include <math-barriers.h>, as can the
other files directly using these barrier macros, and then the include
of <math-barriers.h> from math_private.h can be removed.
Tested for x86_64 and x86. Also tested with build-many-glibcs.py that
installed stripped shared libraries are unchanged by this patch.

Move math_narrow_eval to separate math-narrow-eval.h.
This patch continues cleaning up the math_private.h header, which
contains lots of different definitions many of which are only needed
by a limited subset of files using that header (and some of which are
overridden by architectures that only want to override selected parts
of the header), by moving the math_narrow_eval macro out to a separate
math-narrow-eval.h header, only included by those files that need it.
That header is placed in include/ (since it's used in stdlib/, not
just files built in math/, but no sysdeps variants are needed at
present).
Tested for x86_64, and with build-many-glibcs.py. (Installed stripped
shared libraries change because of line numbers in assertions in
strtod_l.c.)

This complies with the decision of the project leader and primary and
ultimate maintainer, who partially delegated maintainership to myself
and others under certain constraints.
This is also in line with the community-agreed procedures.
It is obvious that we didn't have consensus on a decision to install
that patch, since both sides are still arguing over it.
As for the decision to reverse the deletion, if we even need one to
counter a move that did not have consensus, although nobody else offered
to install the reversal and restore the status prior to the fait
accompli, and some explicitly refused to do so themselves, nobody
objected when I offered to do so. Therefore, by the same reasoning that
led to the mistaken installation of the patch, and after a much longer
wait for objections, I understand there is consensus on my reverting it.

Ignore absolute symbols in ABI tests.
A recent binutils patch
<https://sourceware.org/ml/binutils/2018-04/msg00336.html> stops the
MIPS linker including the _gp_disp absolute symbol in dynamic symbol
tables.
With older binutils, it is included for MIPS o32 (despite the use of
symbol versioning), and this means that all the ABI test baselines for
MIPS o32 include "_gp_disp _gp_disp A". This symbol is not
meaningfully part of the ABI for shared libraries, since it always has
to be resolved at static link time to the local definition for the
linked object.
All the other absolute symbols in ABI test baselines are the names of
symbol versions. I don't think the mere existence of a symbol version
with a given name - as opposed to the contents of that version if
nonempty - is part of the ABI either. Thus, this patch allows the ABI
tests to pass both before and after the binutils change by changing
abilist.awk not to include absolute symbols in its output, and
changing the baselines accordingly.
Tested for x86_64, and with build-many-glibcs.py.

commit 1660901840dfc9fde6c5720a32f901af6f08f00a

Fix blocking pthread_join. [BZ #23137]
On s390 (31bit) if glibc is build with -Os, pthread_join sometimes
blocks indefinitely. This is e.g. observable with
testcase intl/tst-gettext6.
pthread_join is calling lll_wait_tid(tid), which performs the futex-wait
syscall in a loop as long as tid != 0 (thread is alive).
On s390 (and build with -Os), tid is loaded from memory before
comparing against zero and then the tid is loaded a second time
in order to pass it to the futex-wait-syscall.
If the thread exits in between, then the futex-wait-syscall is
called with the value zero and it waits until a futex-wake occurs.
As the thread is already exited, there won't be a futex-wake.
In lll_wait_tid, the tid is stored to the local variable __tid,
which is then used as argument for the futex-wait-syscall.
But unfortunately the compiler is allowed to reload the value
from memory.
With this patch, the tid is loaded with atomic_load_acquire.
Then the compiler is not allowed to reload the value for __tid from memory.
ChangeLog:
[BZ #23137]
* sysdeps/nptl/lowlevellock.h (lll_wait_tid):
Use atomic_load_acquire to load __tid.

x86: Use pad in pthread_unwind_buf to preserve shadow stack register
The pad array in struct pthread_unwind_buf is used by setjmp to save
shadow stack register. We assert that size of struct pthread_unwind_buf
is no less than offset of shadow stack pointer + shadow stack pointer
size.
Since functions, like LIBC_START_MAIN, START_THREAD_DEFN as well as
these with thread cancellation, call setjmp, but never return after
__libc_unwind_longjmp, __libc_unwind_longjmp, which is defined as
__libc_longjmp on x86, doesn't need to restore shadow stack register.
__libc_longjmp, which is a private interface for thread cancellation
implementation in libpthread, is changed to call __longjmp_cancel,
instead of __longjmp. __longjmp_cancel is a new internal function
in libc, which is similar to __longjmp, but doesn't restore shadow
stack register.
The compatibility longjmp and siglongjmp in libpthread.so are changed
to call __libc_siglongjmp, instead of __libc_longjmp, so that they will
restore shadow stack register.
Tested with build-many-glibcs.py.

Deprecate ustat syscall interface
As for sysctl, ustat has been deprecated in favor of {f}statfs. Also
some newer ports which uses generic interface builds a stub version that

Consolidate Linux readahead implementation
This patch consolidate Linux readahead implementation on generic
sysdeps/unix/sysv/linux/readahead.c one. The changes are:
- Assume __NR_readahead existence with current minimum kernel of 3.2
for all architectures.
- Use INLINE_SYSCALL_CALL, __ALIGNMENT_ARG, and SYSCALL_LL64 to pass
the 64 bit offset. This allows architectures with different abis
to use the same implementation.

powerpc64*: fix the order of implied sysdeps directories
The creation of the divergent sysdeps directory for powerpc64le
commit 2f7f3cd8cd302bb10908c86f3f7b349df0a78e6a
Author: Paul E. Murphy <address@hidden>
Date: Fri Jul 15 18:04:40 2016 -0500
powerpc64le: Create divergent sysdep directory for powerpc64le.
allowed float128 to be enabled for powerpc64le (little-endian) and not
for powerpc64 (big-endian). Since the only intended difference between
them was the presence or absence of the float128 interface, the sysdeps
directory for powerpc64le explicitly reused the files from powerpc64
(through the use of Implies files).
Although this works, it also means that files under the powerpc64
directory might be preferred over files under powerpc64le. For
instance, on a build for powerpc64le with target set to power9, a file
from powerpc64/power5 might get built, even though a file with the same
name exists in powerpc64le/power8. That happens because the processor
hierarchy was only defined in the sysdeps directory for powerpc64 (and
borrowed by powerpc64le).
This patch fixes this behavior, by creating new subdirectories under
powerpc64 (i.e.: powerpc64/be and powerpc64/le) and creating new Implies
files to provide the hierarchy of processors for powerpc64 and
powerpc64le separately. These changes have no effect on installed,
stripped binaries (which remain unchanged).
Tested that installed stripped binaries are unchanged and that there are
no regressions on powerpc64 and powerpc64le.

Remove tilegx port.
Since tile support has been removed from the Linux kernel for 4.17,
this patch removes the (unmaintained) port to tilegx from glibc (the
tilepro support having been previously removed). This reflects the
general principle that a glibc port needs upstream support for the
architecture in all the components it build-depends on (so binutils,
GCC and the Linux kernel, for the normal case of a port supporting the
Linux kernel but no other OS), in order to be maintainable.
Apart from removal of sysdeps/tile and sysdeps/unix/sysv/linux/tile,
there are updates to various comments referencing tile for which
removal of those references seemed appropriate. The configuration is
removed from README and from build-many-glibcs.py. contrib.texi keeps
mention of removed contributions, but I updated Chris Metcalf's entry
to reflect that he also contributed the non-removed support for the
generic Linux kernel syscall interface.
__ASSUME_FADVISE64_64_NO_ALIGN support is removed, as it was only used
by tile.

Add tst-sigaction.c to test BZ #23069
This simple test uses sigaction to define a signal handler. It then
uses sigaction again to fetch the information about the same signal
handler, and check that they are consistent. This is enough to detect
mismatches between struct kernel_sigaction and the kernel version of
struct sigaction, like in BZ #23069.

Consolidate getdirentries{64} implementation
This patch consolidates Linux getdirentries{64} implementation on just

Use GCC 8 in build-many-glibcs.py by default.
Now that GCC 8 has branched, this patch makes build-many-glibcs.py
default to using GCC 8 branch instead of GCC 7. The effect should be
that all builds complete cleanly and the compilation parts of the
glibc testsuite complete cleanly except for on i686-gnu (with GCC 7
there were testsuite failures for some other configurations as well).
I've replaced my bot building using GCC 6 branch with one using GCC 8
branch. (Of course glibc should continue building with GCC 6 - and
for that matter GCC 5 and 4.9, which are no longer maintained, are
supported versions as well - but building with GCC 6 will no longer be
included in my bot testing.)
* scripts/build-many-glibcs.py (Context.checkout): Default GCC
version to GCC 8 branch.

Fix Hurd glibc build with GCC 8.
The build of glibc for Hurd has been failing with GCC mainline because
of the checks that aliases have the same type as the symbol aliased;
the Hurd dl-sysdep.c has a macro that defines aliases without using
the proper type. When GCC 8 branches (soon), I intend to make it the
default version in build-many-glibcs.py, so these failures would mean
the default build-many-glibcs.py build fails for Hurd again.
This patch fixes the Hurd build with GCC 8 by changing the macro that
defines the problem aliases to use the correct type for them. An
include of <not-errno.h> is needed to avoid this use of typeof
resulting in an error for __access_noerrno not being declared.
Tested compilation for i686-gnu with build-many-glibcs.py.
* sysdeps/mach/hurd/dl-sysdep.c: Include <not-errno.h>.
(check_no_hidden): Use type of original function when declaring
alias.

Consolidate alphasort{64} and versionsort{64} implementation
This patch consolidates both alphasort{64} and versionsort{64}
implementation on just the default dirent/alphasort{64}c and
dirent/versionsort{64} respectively. It changes the logic
to follow the conventions used on other code consolidation:
* the non-LFS variant is only built for _DIRENT_MATCHES_DIRENT64 being 0.
* the LFS variant is always built and aliased to getdents for ABIs
that define _DIRENT_MATCHES_DIRENT64 to 1.
Also on Linux the compat symbol for old non-LFS dirent64 definition
requires a platform-specific scandir64.c. For powerpc32 and sparcv9
it requires to add specific arch-implementation to override the
generic Linux one because neither ABI exports an compat symbol for
non-LFS alphasort64 and versionsort64 variant. It is most likely a
bug and it is also not one that can be fixed (in that there would be
existing binaries expecting both meanings of that symbol at its single
existing version, with binaries expecting the new meaning probably much
more common than those expecting the original meaning of that symbol at
that version).

Consolidate Linux getdents{64} implementation
This patch consolidates Linux getdents{64} implementation on just
the default sysdeps/unix/sysv/linux/getdents{64}{_r}.c ones.
Although this symbol is used only internally, the non-LFS version
still need to be build due the non-LFS getdirentries which requires
its semantic.
The non-LFS default implementation now uses the wordsize-32 as base
which uses getdents64 syscall plus adjustment for overflow (it allows
to use the same code for architectures that does not support non-LFS
getdents syscall). It has two main differences to wordsize-32 one:
- DIRENT_SET_DP_INO is added to handle alpha requirement to zero
the padding.
- alloca is removed by allocating a bounded temporary buffer (it
increases stack usage by roughly 276 bytes).
The default implementation handle the Linux requirements:
* getdents is only built for _DIRENT_MATCHES_DIRENT64 being 0.
* getdents64 is always built and aliased to getdents for ABIs
that define _DIRENT_MATCHES_DIRENT64 to 1.
* A compat symbol is added for getdents64 for ABI that used to
export the old non-LFS version.
Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu,
sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and
powerpc64le-linux-gnu.

Disable lock elision for mutex pretty printer tests.
If e.g. the testcase nptl/test-mutex-printers is run
with enabled lock-elision, it fails on s390x with:
Error: Response does not match the expected pattern.
Command: print *mutex
Expected pattern: pthread_mutex_t
Response: No symbol "mutex" in current context.
(gdb)
See https://www.sourceware.org/ml/libc-alpha/2018-03/msg00583.html
for more details.
In fact the mutex pretty printer tests rely on looking at the
internal details of the lock, thus we disable it by setting up
the GLIB_TUNABLES environment variable inside gdb.
ChangeLog:
* scripts/test_printers_common.py (init_test): Disable lock elision.

Use volatile global counters in test-tgmath.c.
If build with -Os on s390x, the test-tgmath fails with:
float functions not called often enough (-10000)
Within compile_testf(), the counter (count_float) is saved
before the complex functions are called.
Afterwards the saved counter differs to the current-counter.
But the tests with the complex functions do not increment count_float!
Instead count_float is saved to a register before calling totalorder
and totalordermag which both increment count_float.
The compiler is allowed to do that as totalorderf and totalordermagf
is declared with __attribute__ ((__const__)) in math/bits/mathcalls.h.
Thus this patch adjusts the global counters to be volatile.
Then count_float is saved after totalordermag.
ChangeLog:
* math/test-tgmath.c (count_double, count_float,
count_ldouble, count_cdouble, count_cfloat,
count_cldouble): Use volatile int.

hurd: Fix standard compliance of some statvfs fields

thus merely fix the type.

Make build-many-glibcs.py build GCC for powerpcspe with --enable-obsolete.
The powerpcspe GCC port has been obsoleted in GCC 8 for not having had
the removal of code for non-SPE processors completed. This patch
accordingly arranges for build-many-glibcs.py to configure GCC with
--enable-obsolete for affected configurations. This is temporary;
either the port gets cleaned up and unobsoleted in GCC and the
configure option can be removed, or the port gets removed in GCC and
we should remove the corresponding glibc support.
Tested with build-many-glibcs.py for the affected configurations.
* scripts/build-many-glibcs.py (Context.add_all_configs): Use
--enable-obsolete for powerpc-linux-gnuspe.

arm: Remove ununsed ARM code in optimized implementation
This patch removes the ununsed ARM code path for armv6t2 memchr and
strlen and armv7 memch and strcmp. In all implementation, the ARM
code is not used in any possible build (unless glibc is explicit
build with the non-documented NO_THUMB compiler flag) and for armv7
the resulting code either produces wrong results (memchr) and throw
build error (strcmp).
Checked on arm-linux-gnueabihf built targeting both armv6 and
armv7.

Improves __ieee754_exp(x) performance by 18-37% when |x| < 1.0397
Adds a fast path to e_exp.c when |x| < 1.03972053527832.
When values are tested in isolation, reduction in execution
time is: aarch 30%, sparc 18%, x86 37%.
When comparing benchtests/bench.out which includes values
outside that range, the gains are:
aarch 8%, sparc 5%, x86 9%.
make check is clean (no increase in ulp for any math test).
Testing 20M values for each rounding mode in that range shows
approximately one in 200 values is off by 1 ulp. No value tested
for exp(x) changed by 2 or more ulp.
No observed change in performance or accuracy for x outside
fast path range.
These changes will be active for all platforms that don't provide
their own exp() routines. They will also be active for ieee754
versions of ccos, ccosh, cosh, csin, csinh, sinh, exp10, gamma, and
erf.

S390: Fix struct sigaction for 31bit in kernel_sigaction.h.
The recent commit b4a5d26d8835d972995f0a0a2f805a8845bafa0b
"linux: Consolidate sigaction implementation" changed the definition
of struct sigaction for s390 (31bit). Unfortunately the order of the
fields were wrong.
This leads to blocking testcases e.g. nptl/tst-sem11.
A thread which blocks due to sem_wait() is cancelled via pthread_cancel()
and the signal-handler sigcancel_handler (see <glibc-src>/nptl/nptl-init.c
is called.
But it just returns as the siginfo_t argument is not setup by the kernel.
Then the main-thread is blocking due to pthread_join().
The flag SA_SIGINFO is set in sa_flags in struct sigaction and
is copied to the "kernel_sigaction.h" struct by the sigaction() call,
but due to the wrong ordering of the struct fields,
the kernel does not recognize it.

linux: Consolidate sigaction implementation
This patch consolidates all Linux sigaction implementations on the default
sysdeps/unix/sysv/linux/sigaction.c. The idea is remove redundant code
and simplify new ports addition by following the current generic
Linux User API (UAPI).
The UAPI for new ports defines a generic extensible sigaction struct as:
struct sigaction
{
__sighandler_t sa_handler;
unsigned long sa_flags;
#ifdef SA_RESTORER
void (*sa_restorer) (void);
#endif
sigset_t sa_mask;
};
Where SA_RESTORER is just placed for compatibility reasons (news ports
should not add it). A similar definition is used on generic
kernel_sigaction.h.
The user exported sigaction definition is not changed, so for most
architectures it requires an adjustment to kernel expected one for the
syscall.
The main changes are:
- All architectures now define and use a kernel_sigaction struct meant
for the syscall, even for the architectures where the user sigaction
has the same layout of the kernel expected one (s390-64 and ia64).
Although it requires more work for these architectures, it simplifies
the generic implementation. Also, sigaction is hardly a hotspot where
micro optimization would play an important role.
- The generic kernel_sigaction definition is now aligned with expected
UAPI one for newer ports, where SA_RESTORER and sa_restorer are not
expected to be defined. This means adding kernel_sigaction for
current architectures that does define it (m68k, nios2, powerpc, s390,
sh, sparc, and tile) and which rely on previous generic definition.
- Remove old MIPS usage of sa_restorer. This was removed since 2.6.27
(2957c9e61ee9c - "[MIPS] IRIX: Goodbye and thanks for all the fish").
- The remaining arch-specific sigaction.c are to handle ABI idiosyncrasies
(like SPARC kernel ABI for rt_sigaction that requires an additional
stub argument).
So for new ports the generic implementation should work if its uses
Linux UAPI. If SA_RESTORER is still required (due some architecture
limitation), it should define its own kernel_sigaction.h, define it and
include generic header (assuming it still uses the default generic kernel
layout).
Checked on x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabihf,
aarch64-linux-gnu, sparc64-linux-gnu, sparcv9-linux-gnu, powerpc-linux-gnu,
powerpc64-linux-gnu, ia64-linux-gnu and alpha-linux-gnu. I also checked the
build on all remaining affected ABIs.

manual: Various fixes to the mbstouwcs example, and mbrtowc update
The example did not work because the null byte was not converted, and
mbrtowc was called with a zero-length input string. This results in a
(size_t) -2 return value, so the function always returns NULL.
The size computation for the heap allocation of the result was
incorrect because it did not deal with integer overflow.
Error checking was missing, and the allocated memory was not freed on
error paths. All error returns now set errno. (Note that there is an
assumption that free does not clobber errno.)
The slightly unportable comparision against (size_t) -2 to catch both
(size_t) -1 and (size_t) -2 return values is gone as well.
A null wide character needs to be stored in the result explicitly, to
terminate it.
The description in the manual is updated to deal with these finer
points. The (size_t) -2 behavior (consuming the input bytes) matches
what is specified in ISO C11.

elf: Correct absolute (SHN_ABS) symbol run-time calculation [BZ #19818]
Do not relocate absolute symbols by the base address. Such symbols have
SHN_ABS as the section index and their value is not supposed to be
affected by relocation as per the ELF gABI[1]:
"SHN_ABS
The symbol has an absolute value that will not change because of
relocation."
The reason for our non-conformance here seems to be an old SysV linker
bug causing symbols like _DYNAMIC to be incorrectly emitted as absolute
symbols[2]. However in a previous discussion it was pointed that this
is seriously flawed by preventing the lone purpose of the existence of
absolute symbols from being used[3]:
"On the contrary, the only interpretation that makes sense to me is that
it will not change because of relocation at link time or at load time.
Absolute symbols, from the days of the earliest linking loaders, have
been used to represent addresses that are outside the address space of
the module (e.g., memory-mapped addresses or kernel gateway pages).
They've even been used to represent true symbolic constants (e.g.,
system entry point numbers, sizes, version numbers). There's no other
way to represent a true absolute symbol, while the meaning you seek is
easily represented by giving the symbol a non-negative st_shndx value."
and we ought to stop supporting our current broken interpretation.
Update processing for dladdr(3) and dladdr1(3) so that SHN_ABS symbols
are ignored, because under the corrected interpretation they do not
represent addresses within a mapped file and therefore are not supposed
to be considered.

elf: Unify symbol address run-time calculation [BZ #19818]
Wrap symbol address run-time calculation into a macro and use it
throughout, replacing inline calculations.
There are a couple of variants, most of them different in a functionally
insignificant way. Most calculations are right following RESOLVE_MAP,
at which point either the map or the symbol returned can be checked for
validity as the macro sets either both or neither. In some places both
the symbol and the map has to be checked however.
My initial implementation therefore always checked both, however that
resulted in code larger by as much as 0.3%, as many places know from
elsewhere that no check is needed. I have decided the size growth was
unacceptable.
Having looked closer I realized that it's the map that is the culprit.
Therefore I have modified LOOKUP_VALUE_ADDRESS to accept an additional
boolean argument telling it to access the map without checking it for
validity. This in turn has brought quite nice results, with new code
actually being smaller for i686, and MIPS o32, n32 and little-endian n64
targets, unchanged in size for x86-64 and, unusually, marginally larger
for big-endian MIPS n64, as follows:

Filter out NPTL internal signals (BZ #22391)
This patch filters out the internal NPTL signals (SIGCANCEL/SIGTIMER and
SIGSETXID) from signal functions. GLIBC on Linux requires both signals to
proper implement pthread cancellation, posix timers, and set*id posix
thread synchronization.
And not filtering out the internal signal is troublesome:
- A conformant program on a architecture that does not filter out the
signals might inadvertently disable pthread asynchronous cancellation,
set*id synchronization or posix timers.
- It might also to security issues if SIGSETXID is masked and set*id
functions are called (some threads might have effective user or group
id different from the rest).
The changes are basically:
- Change __is_internal_signal to bool and used on all signal function
that has a signal number as input. Also for signal function which
accepts
signals sets (sigset_t) it assumes that canonical function were used to
add/remove signals which lead to some input simplification.
- Fix tst-sigset.c to avoid check for SIGCANCEL/SIGTIMER and SIGSETXID.
It is rewritten to check each signal indidually and to check realtime
signals using canonical macros.
- Add generic __clear_internal_signals and __is_internal_signal
version since both symbols are used on generic implementations.
- Remove superflous sysdeps/nptl/sigfillset.c.
- Remove superflous SIGTIMER handling on Linux __is_internal_signal
since it is the same of SIGCANCEL.
- Remove dangling define and obvious comment on nptl/sigaction.c.
Checked on x86_64-linux-gnu.

[PATCH 7/7] sin/cos slow paths: refactor sincos implementation
Refactor the sincos implementation - rather than rely on odd partial
inlining
of preprocessed portions from sin and cos, explicitly write out the cases.
This makes sincos much easier to maintain and provides an additional 16-20%
speedup between 0 and 2^27. The overall speedup of sincos is 48% over this
range.
Between 0 and PI it is 66% faster.

(__cos): Likewise.
* sysdeps/ieee754/dbl-64/s_sin.c (__sincos): Refactor using the same
logic as sin and cos.

[PATCH 6/7] sin/cos slow paths: refactor duplicated code into dosin
Refactor duplicated code into do_sin. Since all calls to do_sin use
copysign to
set the sign of the result, move it inside do_sin. Small inputs use a
separate
polynomial, so move this into do_sin as well (the check is based on the more
conservative case when doing large range reduction, but could be relaxed).
* sysdeps/ieee754/dbl-64/s_sin.c (do_sin): Use TAYLOR_SIN for small
inputs. Return correct sign.
(do_sincos): Remove small input check before do_sin, let do_sin set
the sign.

[PATCH 3/7] sin/cos slow paths: remove slow paths from small range reduction
This patch improves the accuracy of the range reduction. When the input is
large (2^27) and very close to a multiple of PI/2, using 110 bits of PI is
not
enough. Improve range reduction accuracy to 136 bits. As a result the
special
checks for results close to zero can be removed. The ULP of the
polynomials is
at worst 0.55ULP, so there is no reason for the slow functions, and they
can be
removed.
* sysdeps/ieee754/dbl-64/s_sin.c (reduce_sincos_1): Rename to
reduce_sincos, improve accuracy to 136 bits.

[PATCH 2/7] sin/cos slow paths: remove large range reduction
This patch removes the large range reduction code and defers to the huge
range
reduction code. The first level range reducer supports inputs up to 2^27,
which is way too large given that inputs for sin/cos are typically small
(< 10), and optimizing for a smaller range would give a significant speedup.
Input values above 2^27 are practically never used, so there is no reason
for
supporting range reduction between 2^27 and 2^48. Removing it significantly
simplifies code and enables further speedups. There is about a 2.3x
slowdown
in this range due to __branred being extremely slow (a better algorithm
could
easily more than double performance).

[PATCH 1/7] sin/cos slow paths: avoid slow paths for small inputs
This series of patches removes the slow patchs from sin, cos and sincos.
Besides greatly simplifying the implementation, the new version is also much
faster for inputs up to PI (41% faster) and for large inputs needing range
reduction (27% faster).
ULP is ~0.55 with no errors found after testing 1.6 billion inputs across
most
of the range with mpsin and mpcos. The number of incorrectly rounded
results
(ie. ULP >0.5) is at most ~2750 per million inputs between 0.125 and 0.5,
the average is ~850 per million between 0 and PI.
Tested on AArch64 and x86_64 with no regressions.
The first patch removes the slow paths for the cases where the input is
small
and doesn't require range reduction. Update ULP tables for sin, cos and
sincos
on AArch64 and x86_64.
* sysdeps/aarch64/libm-test-ulps: Update ULP for sin, cos, sincos.
* sysdeps/ieee754/dbl-64/s_sin.c (__sin): Remove slow paths for small
inputs.
(__cos): Likewise.

Assume O_DIRECTORY for opendir
This patch assumes O_DIRECTORY works as defined by POSIX on opendir
implementation (aligning with other glibc code, for instance pwd). This
allows remove both the fallback code to handle system with missing or
broken O_DIRECTORY along with the Linux specific opendir.c which just
advertise the working flag.
Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu,

sparc: Fix arch_fork definition
This patch fixes 3dc214977 for sparc. Different than other architectures
SPARC kernel Kconfig does not define CONFIG_CLONE_BACKWARDS, however it
has the same ABI as if it did, implemented by sparc-specific code
(sparc_do_fork).
It also has a unique return value convention for clone:
Parent --> %o0 == child's pid, %o1 == 0
Child --> %o0 == parent's pid, %o1 == 1
Which required a special macro to correct issue the syscall
(INLINE_CLONE_SYSCALL).
Checked on sparc64-linux-gnu and sparcv9-linux-gnu.

Unify umount function implementations (bug 16552).
Linux kernel architectures have various arrangements for umount
syscalls. There is a syscall that takes flags, and an older one that
does not. Newer architectures have only the one taking flags, under
the name umount2 (or under the name umount, in the ia64 case). Older
architectures may have both, under the names umount2 and umount (or
under the names umount and oldumount, in the alpha case). glibc then
has several similar implementations of the umount function (no flags)
in terms of either the __umount2 function, or the corresponding
syscall, or in terms of the old syscall under either of its names.
This patch simplifies the implementations in glibc by always using the
__umount2 function to implement the umount function on all systems
using the Linux kernel. The linux/generic implementation is moved to
sysdeps/unix/sysv/linux (without any changes to code or comments) and
all the other variants are removed. (This will have the effect of
causing the new syscall to be used in some cases that previously used
the old one, but as discussed for previous changes, such a change to
the underlying syscalls used is OK.)
There remain two variants of how the __umount2 function is
implemented, either in umount2.S, or, for ia64, in syscalls.list.
Tested with build-many-glibcs.py.

Remove unused frame.h header, sigcontextinfo.h macros.
The glibc-internal header frame.h was used in the old
debug/backtrace.c but is now unused. Similarly, there are some
sigcontextinfo.h macros that are used nowhere in glibc -
ADVANCE_STACK_FRAME and FIRST_FRAME_POINTER were used in the old
debug/backtrace.c, while SIGCONTEXT_EXTRA_ARGS, GET_FRAME, GET_STACK
and CALL_SIGHANDLER were unused even before the removal of that old

Use x86_64 backtrace as generic version.
No glibc configuration uses the present debug/backtrace.c, whereas
several #include the x86_64 version. The x86_64 version is
effectively a generic one (using _Unwind_Backtrace from libgcc, which
works much more reliably than the built-in functions used by
debug/backtrace.c). This patch moves it to debug/backtrace.c and
removes all the #includes of the x86_64 version from other
architectures which are no longer required.
I do not know whether all the other architecture-specific backtrace
implementations that are based on _Unwind_Backtrace are required, or
whether, where their differences from the generic version do something
useful, suitable hooks could be added to the generic version to reduce
the duplication involved.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by this patch.

Remove powerpc, sparc fdim inlines (bug 22987).
The powerpc and sparc bits/mathinline.h include inlines of fdim and
fdimf. These are not restricted to -fno-math-errno, but do not set
errno, and wrongly use ordered <= comparisons instead of the required
islessequal comparisons (this latter issue is latent on powerpc
because GCC wrongly uses unordered comparison instructions for
operations that should use ordered comparison instructions).
Since we wish to avoid such header inlines anyway, leaving it to the
compiler to inline such standard functions under appropriate
conditions, this patch fixes those issues by removing the inlines in
question (and thus removing the sparc bits/mathinline.h header which
had no other inlines left in it). I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85003> for adding
correct fdim inlines to GCC, since the function is simple enough that
a correct inline is a perfectly reasonable architecture-independent
optimization with -fno-math-errno and in the absence of implicit
excess precision.
Tested with build-many-glibcs.py for all its powerpc and sparc
configurations.

* sysdeps/powerpc/bits/mathinline.h (fdim): Remove inline
function.
(fdimf): Likewise.

Fix signed integer overflow in random_r (bug 17343).
Bug 17343 reports that stdlib/random_r.c has code with undefined
behavior because of signed integer overflow on int32_t. This patch
changes the code so that the possibly overflowing computations use
unsigned arithmetic instead.
Note that the bug report refers to "Most code" in that file. The
places changed in this patch are the only ones I found where I think
such overflow can occur.
Tested for x86_64 and x86.
[BZ #17343]
* stdlib/random_r.c (__random_r): Use unsigned arithmetic for
possibly overflowing computations.

Add narrowing subtract functions.
This patch adds the narrowing subtract functions from TS 18661-1 to
glibc's libm: fsub, fsubl, dsubl, f32subf64, f32subf32x, f32xsubf64
for all configurations; f32subf64x, f32subf128, f64subf64x,
f64subf128, f32xsubf64x, f32xsubf128, f64xsubf128 for configurations
with _Float64x and _Float128; __nldbl_dsubl for ldbl-opt.
The changes are essentially the same as for the narrowing add
functions, so the description of those generally applies to this patch
as well.
Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft
float) and powerpc, and with build-many-glibcs.py.

Appending / to the path to be looked up would make us always follow a final

the node and stat it, which we already do anyway, and check for
directory type.

Remove sysdeps/x86/fpu/bits/mathinline.h __finite inline.
Continuing the removals of inline functions from the x86
bits/mathinline.h, this patch removes an inline of __finite (which was
not actually architecture-specific at all beyond its
endianness-dependence).
This inline is not normally used with GCC 4.4 or later, because
isfinite now uses __builtin_isfinite except for -fsignaling-nans.
Allowing __builtin_isfinite etc. to work properly even for
-fsignaling-nans, by implementing versions of those built-in functions
that use integer arithmetic in GCC, is
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66462> (a patch was
committed but had to be reverted because it caused problems, and that
patch didn't address all formats for all architectures, only some, so
by itself would not have been sufficient to allow glibc to use
__builtin_isfinite unconditionally for new-enough GCC).
Tested for x86_64 and x86.
* sysdeps/x86/fpu/bits/mathinline.h [__USE_MISC] (__finite):
Remove inline function.

Remove all target specific __ieee754_sqrt(f/l) inlines
Remove the now unused target specific__ieee754_sqrt(f/l) inlines.
Also remove inlines of sqrt which are for really old GCC versions.
Removing these is desirable, under the general principle of leaving
such inlining to the compiler rather than trying to do it in installed
headers, especially when only very old compilers are affected.
Note that removing inlines for __ieee754_sqrt disables inlining in the
sqrt wrapper functions. Given the sqrt function will typically only be
called for negative arguments, it doesn't matter whether the inlining
happens or not.

Add support for sqrt asm redirects
This patch series cleans up the many uses of __ieee754_sqrt(f/l) in GLIBC.
The goal is to enable GCC to do the inlining, and if this fails call the
__ieee754_sqrt function. This is done by internally declaring sqrt with asm
redirects. The compat symbols and sqrt wrappers need to disable the
redirect.
The redirect is also disabled if there are already redirects defined when
using -ffinite-math-only.
All math functions (but not math tests, non-library code and libnldbl) are
built with -fno-math-errno which means GCC will typically inline sqrt as a
single instruction. This means targets are no longer forced to add a
special
inline for sqrt.

Remove more old-compilers parts of sysdeps/x86/fpu/bits/mathinline.h.
This patch removes further parts of sysdeps/x86/fpu/bits/mathinline.h
that are only of value for optimization with older compiler versions,
in accordance with general principles of preferring the let the
compiler deal with such inlining through built-in functions.
In general, GCC supports inlining all these functions as of version
4.3 or earlier. However, some inlines in GCC may have had excessively
restrictive conditions in past GCC versions (e.g. requiring
-ffast-math when the inline is valid under broader conditions). (In
particular, GCC had, before GCC 7, unnecessarily restrictive
conditions on when it could apply floor and ceil inlines corresponding
to the ones removed here. The same was true for rint, but
bits/mathinline.h *also* was excessively restrictive there.)
The removed sincos inlines are for __sincos etc. functions (not a
public interface and not currently used in this header either; not in
a part of the header ever used for building glibc itself). Likewise,
the atan2 inlines included one for __atan2l, also not a public
interface and not used for building glibc itself (calls inside glibc
generally use __ieee754_atan2l, for which there is a separate
__LIBC_INTERNAL_MATH_INLINES case in this header).
Tested for x86_64 and x86.

Remove old-GCC parts of x86 bits/mathinline.h.
In accordance with the general principle of preferring to let the
compiler optimize function calls based on their standard semantics
rather than putting inline definitions of such functions in installed
headers, this patch removes various such inline definitions in the x86
bits/mathinline.h that were already disabled for GCC 3.5 or later and
so were only used with very old compilers (for which good optimization
is particularly unimportant); along with those inlines, a definition
of __M_SQRT2, which was only used in such inline functions, is also
removed. This is similar to an early step in removing the string.h
inlines; I intend to follow up with further removals of
bits/mathinline.h inline definitions in appropriate logical groups
(with GCC bugs filed in cases where GCC doesn't already support
corresponding optimizations).
Tested for x86_64 and x86.

aarch64: Improve strncmp for mutually misaligned inputs
The mutually misaligned inputs on aarch64 are compared with a simple
byte copy, which is not very efficient. Enhance the comparison
similar to strcmp by loading a double-word at a time. The peak
performance improvement (i.e. 4k maxlen comparisons) due to this on
the strncmp microbenchmark is as follows:
falkor: 3.5x (up to 72% time reduction)
cortex-a73: 3.5x (up to 71% time reduction)
cortex-a53: 3.5x (up to 71% time reduction)
All mutually misaligned inputs from 16 bytes maxlen onwards show
upwards of 15% improvement and there is no measurable effect on the
performance of aligned/mutually aligned inputs.
* sysdeps/aarch64/strncmp.S (count): New macro.
(strncmp): Store misaligned length in SRC1 in COUNT.
(mutual_align): Adjust.
(misaligned8): Load dword at a time when it is safe.

[BZ 1190] Make EOF sticky in stdio.
C99 specifies that the EOF condition on a file is "sticky": once EOF
has been encountered, all subsequent reads should continue to return
EOF until the file is closed or something clears the "end-of-file
indicator" (e.g. fseek, clearerr). This is arguably a change from
C89, where the wording was ambiguous; the BSDs always had sticky EOF,
but the System V lineage would attempt to read from the underlying fd
again. GNU libc has followed System V for as long as we've been
using libio, but nowadays C99 conformance and BSD compatibility are
more important than System V compatibility.
You might wonder if changing the _underflow impls is sufficient to
apply the C99 semantics to all of the many stdio functions that
perform input. It should be enough to cover all paths to _IO_SYSREAD,
and the only other functions that call _IO_SYSREAD are the _seekoff
impls, which is OK because seeking clears EOF, and the _xsgetn impls,
which, as far as I can tell, are unused within glibc.
The test programs in this patch use a pseudoterminal to set up the
necessary conditions. To facilitate this I added a new test-support
function that sets up a pair of pty file descriptors for you; it's
almost the same as BSD openpty, the only differences are that it
allocates the optionally-returned tty pathname with malloc, and that
it crashes if anything goes wrong.

nldbl-compat.c: Include math.h before nldbl-compat.h.
Jeff Law noticed that native PowerPC builds were broken by my having
made math_ldbl_opt.h not include math.h. nldbl-compat.c formerly got
math.h via libioP.h and math_ldbl_opt.h, *without* __NO_LONG_DOUBLE_MATH;
after my change it got it via nldbl-compat.h *with* __NO_LONG_DOUBLE_MATH,
but __NO_LONG_DOUBLE_MATH mode is forbidden on hosts that define
__HAVE_DISTINCT_FLOAT128, so the build breaks. This is the quick fix.

assembler, in the expansion of pseudo-instructions. It's also used

sparc32: Add nop before __startcontext to stop unwinding [BZ #22919]
On sparc32 tst-makecontext fails, as backtrace called within a context
created by makecontext to yield infinite backtrace.
Fix that the same way than nios2 by adding a nop just before
__startcontext. This is needed as otherwise FDE lookup just repeatedly
finds __setcontext's FDE in an infinite loop, due to the convention of
using 'address - 1' for FDE lookup.

powerpc: Fix TLE build for SPE (BZ #22926)
Some SPE opcodes clashes with some recent PowerISA opcodes and
until recently gas did not complain about it. However binutils
recently changed it and now VLE configured gas does not support to
assembler some instruction that might class with VLE (HTM for
instance). It also does not help that glibc build hardware lock
elision support as default (regardless of assembler support).
Although runtime will not actually enables TLE on SPE hardware
(since kernel will not advertise it), I see little advantage on
adding HTM support on SPE built glibc. SPE uses an incompatible
ABI which does not allow share the same build with default
powerpc and HTM code slows down SPE without any benefict.
This patch fixes it by only building HTM when SPE configuration
is not used.
Checked with a powerpc-linux-gnuspe build. I also did some sniff
tests on a e500 hardware without any issue.

Refactor Linux ARCH_FORK implementation
This patch refactors the ARCH_FORK macro and the required architecture
specific header to simplify the required architecture definitions
to provide the fork syscall semantic and proper document current

Instead of require the reimplementation of arch-fork.h header, this
patch changes the ARCH_FORK to an inline function with clone ABI
defined by kernel-features.h define. The generic kernel ABI meant
for newer ports is used as default and redefine if the architecture
requires.

aarch64: Optimized memcmp for medium to large sizes
This improved memcmp provides a fast path for compares up to 16 bytes
and then compares 16 bytes at a time, thus optimizing loads from both
sources. The glibc memcmp microbenchmark retains performance (with an
error of ~1ns) for smaller compare sizes and reduces up to 31% of
execution time for compares up to 4K on the APM Mustang. On Qualcomm
Falkor this improves to almost 48%, i.e. it is almost 2x improvement
for sizes of 2K and above.
* sysdeps/aarch64/memcmp.S: Widen comparison to 16 bytes at a

Fix s390 -Os iconv build.
Building glibc for s390 with -Os (32-bit only, with GCC 7) fails with:
In file included from ../sysdeps/s390/multiarch/8bit-generic.c:370:0,
from ebcdic-at-de.c:28:
../iconv/loop.c: In function '__to_generic_vx':
../iconv/loop.c:264:22: error: 'ch' may be used uninitialized in this

here
uint32_t ch; \
^
../iconv/loop.c:325:7: note: in expansion of macro 'BODY'
BODY
^~~~
It's fairly easy to see, looking at the (long) expansion of the BODY
macro, that this is a false positive and the relevant variable 'ch' is
always initialized before use, in one of two possible places. As
such, disabling the warning for -Os with the DIAG_* macros is the
natural approach to fix this build failure. However, because of the
location at which the warning is reported, the disabling needs to go
in iconv/loop.c, around the definition of UNICODE_TAG_HANDLER (not
inside the definition), as that macro definition is where the
uninitialized use is reported, whereas the code that needs to be
reasoned about to see that the warning is a false positive is in the
definition of BODY elsewhere.
Thus, the patch adds such disabling in iconv/loop.c, with a comment
pointing to the s390-specific code and a comment in the s390-specific
code pointing to the generic file to alert people to the possible need
to update one place when changing the other. It would be possible if
desired to use #ifdef __s390__ around the disabling, though in general
we try to avoid that sort of thing in generic files. (Or some
extremely specialized macros for "disable -Wmaybe-uninitialized in
this particular place" could be specified, defined to 0 in a lot of
different files that include iconv/loop.c and to 1 in that particular
s390 file.)
Tested that this fixed -Os compilation for s390-linux-gnu with
build-many-glibcs.py.
* iconv/loop.c (UNICODE_TAG_HANDLER): Disable
-Wmaybe-uninitialized for -Os.
* sysdeps/s390/multiarch/8bit-generic.c (BODY): Add comment about

nptl: Fix tst-cancel4 sendto tests
Now that send might be implemented calling sendto syscall on Linux,
I am seeing some issue in some kernel configurations where tst-cancel4
sendto do not block as expected.
The socket used to force the syscall blocking is used with default
system configuration for buffer sending size, which might not be
suffice to force blocking. This patch fixes it by explicit setting
buffer socket lower than the buffer size used. It also enables sendto
cancellation tests to work in both ways (since internally send is
implemented routing to sendto on Linux kernel).
The patch also removes unrequired make rules on some archictures
for send/recv. The generic nptl Makefile already set the compiler flags
required on some architectures for correct unwinding and libc object
are not strictly required to support unwind (since pthread_cancel
requires linking against libpthread).
Checked on aarch64-linux-gnu and x86_64-linux-gnu. I also did a
sniff test with tst-cancel{4,5} on a simulated mips64-linux-gnu.

i386: Fix i386 sigaction sa_restorer initialization (BZ#21269)
This patch fixes the i386 sa_restorer field initialization for sigaction
syscall for kernel with vDSO. As described in bug report, i386 Linux
(and compat on x86_64) interprets SA_RESTORER clear with nonzero
sa_restorer as a request for stack switching if the SS segment is 'funny'.
This means that anything that tries to mix glibc's signal handling with
segmentation (for instance through modify_ldt syscall) is randomly broken
depending on what values lands in sa_restorer.
The testcase added is based on Linux test
tools/testing/selftests/x86/ldt_gdt.c,
more specifically in do_multicpu_tests function. The main changes are:
- C11 atomics instead of plain access.
- Remove x86_64 support which simplifies the syscall handling and
fallbacks.
- Replicate only the test required to trigger the issue.
Checked on i686-linux-gnu.

[BZ #22342] Fix netgroup cache keys.
Unlike other nscd caches, the netgroup cache contains two types of
records - those for "iterate through a netgroup" (i.e. setnetgrent())
and those for "is this user in this netgroup" (i.e. innetgr()),
i.e. full and partial records. The timeout code assumes these records
have the same key for the group name, so that the collection of records
that is "this netgroup" can be expired as a unit.
However, the keys are not the same, as the in-netgroup key is generated
by nscd rather than being passed to it from elsewhere, and is generated
without the trailing NUL. All other keys have the trailing NUL, and as
noted in the linked BZ, debug statements confirm that two keys for the
same netgroup are added to the cache with two different lengths.
The result of this is that as records in the cache expire, the purge
code only cleans out one of the two types of entries, resulting in
stale, possibly incorrect, and possibly inconsistent cache data.
The patch simply includes the existing NUL in the computation for the
key length ('key' points to the char after the NUL, and 'group' to the
first char of the group, so 'key-group' includes the first char to the
NUL, inclusive).
[BZ #22342]
* nscd/netgroupcache.c (addinnetgrX): Include trailing NUL in
key value.

Fix i386 fenv_private.h float128 for 32-bit --with-fpmath=sse (bug 22902).
As discussed in bug 22902, the i386 fenv_private.h implementation has
problems for float128 for the case of 32-bit glibc built with libgcc
from GCC configured using --with-fpmath=sse.
The optimized floating-point state handling in fenv_private.h needs to
know which floating-point state - x87 or SSE - is used for each
floating-point type, so that only one state needs updating / testing
for libm code using that state internally. On 32-bit x86, the x87
rounding mode is always used for float128, but the x87 exception flags
are only used when libgcc is built using x87 floating-point
arithmetic; if libgcc is built for SSE arithmetic, the SSE exception
flags are used.
The choice of arithmetic with which libgcc is built is independent of
that with which glibc is built. Thus, since glibc cannot tell the
choice used in libgcc, the default implementations of
libc_feholdexcept_setroundf128 and libc_feupdateenv_testf128 (which

Use libc_hidden_* for strtoumax (bug 15105).
On sparc, localplt test failures appear when building with -Os because
of a call to strtoumax from
sysdeps/unix/sysv/linux/sparc/sparc64/get_clockfreq.c, and strtoumax
is not inlined when building with -Os. This patch fixes those
failures by using libc_hidden_proto and libc_hidden_def for strtoumax.
Tested with build-many-glibcs.py for
sparc64-linux-gnu-disable-multi-arch, sparc64-linux-gnu,
sparcv9-linux-gnu-disable-multi-arch, sparcv9-linux-gnu that this
fixes that test failure with -Os.

Fix two more -Os strcoll / wcscoll build failures.
Continuing fixes for -Os build issues shown with build-many-glibcs.py,
this patch adds uses of DIAG_* to disable -Wmaybe-uninitialized in two
more places where code inlined from strcoll / wcscoll is wrongly
diagnosed as possibly using uninitialized structure fields. (All
these warnings in different places for these functions are I think
essentially the same bug.)
Tested with build-many-glibcs.py for alpha-linux-gnu and
mips-linux-gnu that this fixes the -Os build failures for those
configurations with GCC 7.
* locale/weightwc.h (findidx): Ignore -Wmaybe-uninitialized for
-Os in two more places.

Remove the lines from cmn_TW.UTF-8.in which cannot work at the moment.
See this bug https://sourceware.org/bugzilla/show_bug.cgi?id=22898
These lines donât yet work because of a glibc bug, not because of
problems in the locale data. No matter what sorting rules one uses,
these characters cannot be sorted at all at the moment.
As soon as that bug is fixed, these lines should be added back to the

Therefore, using [a-z] does not make much sense except in the C/POSIX
locale.
The new iso14651_t1_common lists upper case and lower case Latin characters
in a different order than the old one which causes surprising results
for example in the de_DE locale: [a-z] now includes A because A comes
after a in iso14651_t1_common but does not include Z because that comes
after z in iso14651_t1_common.
* posix/tst-fnmatch.input: Fix results for range expressions
for non C locales.
* posix/tst-regexloc.c: Do not use a range expression for
de_DE.ISO-8859-1 locale.

Fix posix/bug-regex5.c test case, adapt to iso14651_t1_common upate
This test case tests how many collating elements are defined in
da_DK.ISO-8859-1 locale. The da_DK locale source defines 4:
collating-element <A-A> from "<U0041><U0041>"
collating-element <A-a> from "<U0041><U0061>"
collating-element <a-A> from "<U0061><U0041>"
collating-element <a-a> from "<U0061><U0061>"
The new iso14651_t1_common file defines more collating elements, two
of them are in the ISO-8859-1 range:
collating-element <U004C_00B7> from "<U004C><U00B7>" % decomposition of
LATIN CAPITAL LETTER L WITH MIDDLE DOT
collating-element <U006C_00B7> from "<U006C><U00B7>" % decomposition of
LATIN SMALL LETTER L WITH MIDDLE DOT
So the total count is now 6 instead of 4.
* posix/bug-regex5.c: Fix test case because with the new
iso14651_t1_common file, the da_DK locale now has 6 collating
elements
in the ISO-8859-1 range instead of 4 with the old iso14651_t1_common
file.

iso14651_t1_common: make the fourth level the codepoint for characters
which are ignorable on all 4 levels
Entries for characters which have âIGNOREâ on all 4 levels like:
<U0001> IGNORE;IGNORE;IGNORE;IGNORE % START OF HEADING (in ISO 6429)
are changed into:
<U0001> IGNORE;IGNORE;IGNORE;<U0001> % START OF HEADING (in ISO 6429)
i.e. putting the code point of the character into the fourth level
instead of âIGNOREâ. Without that change, all such characters
would compare equal which would make a wcscoll test case fail.
It is better to have a clearly defined sort order even for characters
like this so it is good to use the code point as a tie-break.
* localedata/locales/iso14651_t1_common: Use the code point of a
character in the fourth collation level instead of IGNORE for all

File downloaded from:

Updating this file alone is not enough, there are problems in the new
file which need to be fixed and the collation rules for many locales
need to be adapted. This is done by the following patches.
This update also fixes the problem that many characters are treated as
identical when sorting because they were not yet in the old
iso14651_t1_common file, see:
https://bugzilla.redhat.com/show_bug.cgi?id=1336308

Fix another -Os strcoll build issue.
While there are now clean -Os build and test results on x86_64 (given
my patch <https://sourceware.org/ml/libc-alpha/2018-02/msg00602.html>,
pending review), testing with -Os with build-many-glibcs.py shows the
build is still failing with -Os everywhere except for x86_64, x86 and
s390x.
There are a variety of different build failures, but the most common
seem to be in strcoll / wcscoll, similar to existing such cases where
DIAG_* are used to disable -Wmaybe-uninitialized. There are various
different failures even within those functions. This patch fixes one
particular case that seems quite common, where the warning appears at
the declarations of seq1 and seq2.
Tested with build-many-glibcs.py that this fixes the -Os build for
aarch64-linux-gnu with GCC 7.
* string/strcoll_l.c: Include <libc-diag.h>.
(STRCOLL): Ignore -Wmaybe-uninitialized for -Os around

Use libc_hidden_* for atoi (bug 15105).
Continuing the fixes for localplt test failures with -Os arising from
functions not being inlined in that case, this patch fixes such

Tested for x86_64 (both that it removes this particular localplt
failure for -Os, and that the testsuite continues to pass without
-Os).

Define GEN_AS_CONST_HEADERS when generating header files [BZ #22792]
Glibc build generates header files to define constants from special .sym
files. If a .sym file includes the same header file which it generates,
it leads to circular dependency which may lead to build hang on a
many-core machine. Define GEN_AS_CONST_HEADERS when generating header
files to avoid circular dependency.
<tcb-offsets.h> is needed for i686 and it isn't needed for x86-64 at
least since glibc 2.23.
Tested on i686 and x86-64.
[BZ #22792]
* Makerules ($(common-objpfx)%.h): Pass -DGEN_AS_CONST_HEADERS
to $(CC).
* sysdeps/unix/sysv/linux/i386/lowlevellock.h: Include
<tcb-offsets.h> only if GEN_AS_CONST_HEADERS isn't defined.
* sysdeps/unix/sysv/linux/x86_64/lowlevellock.h: Don't include
<tcb-offsets.h>.

Use libc_hidden_* for tolower, toupper (bug 15105).
Continuing the fixes for localplt test failures with -Os arising from
functions not being inlined in that case, this patch fixes such
failures for tolower and toupper by using libc_hidden_proto and
libc_hidden_def.
Tested for x86_64 (both that it removes this particular localplt
failure for -Os, and that the testsuite continues to pass without
-Os).

Refactor atfork handlers
Current implementation (sysdeps/nptl/fork.c) replicates the atfork
handlers list backward to invoke the child handlers after fork/clone
syscall.
The internal atfork handlers is implemented as a single-linked list
so a lock-free algorithm can be used, trading fork mulithread call
performance for some code complexity and dynamic stack allocation
(since the backwards list should not fail).
This patch refactor it to use a dynarary instead of a linked list.
It simplifies the external variables need to be exported and also
the internal atfork handler member definition.
The downside is a serialization of fork call in multithread, since to
operate on the dynarray the internal lock should be used. However
as noted by Florian, it already acquires external locks for malloc
and libio so it is already hitting some lock contention. Besides,
posix_spawn should be faster and more scalable to run external programs
in multithread environments.

Rename nptl-signals.h to internal-signals.h
This patch renames the nptl-signals.h header to internal-signals.h.
On Linux the definitions and functions are not only NPTL related, but
used for other POSIX definitions as well (for instance SIGTIMER for
posix times, SIGSETXID for id functions, and signal block/restore
helpers) and since generic functions will be places and used in generic
implementation it makes more sense to decouple it from NPTL.

Remove miscellaneous debris from libio.
This patch eliminates a number of #if 0 and #ifdef TODO blocks, macros
that are never used, macros that provide portability to substrates that
lack basic things like EINVAL and off_t, and other such debris.
I preserved IO_DEBUG and CHECK_FILE, even though as far as I can tell
IO_DEBUG is never defined and therefore CHECK_FILE never does
anything, because it seems like we might actually want to turn it _on_.
Installed stripped libraries and executables are unchanged, except,
again, that the line number of an assertion changes (this time it's
somewhere in fileops.c).
* libio/libio.h (_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust):
Define here, unconditionally.
* libio/iolibio.h (_IO_pos_BAD): Don't define here.
* libio/libioP.h: Remove #if 0 blocks.
(_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust): Don't define here.
(_IO_va_start, COERCE_FILE, MAYBE_SET_EINVAL): Don't define.
(CHECK_FILE): Don't use MAYBE_SET_EINVAL or COERCE_FILE. Fix style.
* libio/clearerr.c, libio/fputc.c, libio/getchar.c:
Assume weak_alias is always defined.
* libio/fileops.c, libio/genops.c, libio/oldfileops.c
* libio/oldpclose.c, libio/pclose.c, libio/wfileops.c:
Remove #if 0 and #ifdef TODO blocks.
Assume text_set_element is always defined.
* libio/iofdopen.c, libio/iogetdelim.c, libio/oldiofdopen.c
Use __set_errno (EINVAL) instead of MAYBE_SET_EINVAL.
* libio/tst-mmap-eofsync.c: Make #if 1 block unconditional.

(_IO_fwide_maybe_incompatible): Use __glibc_unlikely.
* libio/libioP.h (EOF): Don't define.
* libio/iofdopen.c, libio/iofopen.c, libio/iopopen.c
* libio/iovdprintf.c, libio/oldiofdopen.c, libio/oldiofopen.c
* libio/oldiopopen.c, debug/vdprintf_chk.c: Remove #if block
testing _IO_UNIFIED_JUMPTABLES.

Mechanically remove _IO_ name aliases for types and constants.
This patch mechanically removes all remaining uses, and the
definitions, of the following libio name aliases:
name replaced with
---- -------------
_IO_FILE FILE
_IO_fpos_t __fpos_t
_IO_fpos64_t __fpos64_t
_IO_size_t size_t
_IO_ssize_t ssize_t or __ssize_t
_IO_off_t off_t
_IO_off64_t off64_t
_IO_pid_t pid_t
_IO_uid_t uid_t
_IO_wint_t wint_t
_IO_va_list va_list or __gnuc_va_list
_IO_BUFSIZ BUFSIZ
_IO_cookie_io_functions_t cookie_io_functions_t
__io_read_fn cookie_read_function_t
__io_write_fn cookie_write_function_t
__io_seek_fn cookie_seek_function_t
__io_close_fn cookie_close_function_t
I used __fpos_t and __fpos64_t instead of fpos_t and fpos64_t because
the definitions of fpos_t and fpos64_t depend on the largefile mode.
I used __ssize_t and __gnuc_va_list in a handful of headers where
namespace cleanliness might be relevant even though they're
internal-use-only. In all other cases, I used the public-namespace
name.
There are a tiny handful of places where I left a use of 'struct _IO_FILE'
alone, because it was being used together with 'struct _IO_FILE_plus'
or 'struct _IO_FILE_complete' in the same arithmetic expression.
Because this patch was almost entirely done with search and replace, I
may have introduced indentation botches. I did proofread the diff,
but I may have missed something.
The ChangeLog below calls out all of the places where this was not a
pure search-and-replace change.
Installed stripped libraries and executables are unchanged by this patch,
except that some assertions in vfscanf.c change line numbers.

Fix -Os putc_unlocked, fputc_unlocked linknamespace, localplt issues (bug
15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for putc_unlocked and fputc_unlocked.
libc_hidden_* are used for both functions, while namespace issues are
addressed by making putc_unlocked a weak alias of hidden
__putc_unlocked, which is called in the one place where namespace
issues arise (and defined as an inline function in include/stdio.h).
Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and
localplt test failures are resolved). This completes fixing the -Os
linknamespace failures (at least for x86_64); localplt failures remain
after this patch.

Fix -Os getc_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for getc_unlocked.
__getc_unlocked already exists; this patch makes it explicitly hidden,
calls it where needed for namespace reasons, adds an inline function
for it when inline functions are used and adds libc_hidden_proto /
libc_hidden_weak for getc_unlocked.
Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and
localplt test failures are resolved). Because of other such failures
that remain after this patch, neither of the bugs can yet be closed.

manual: Update _DEFAULT_SOURCE. [BZ #22862]
The description of the interplay between feature test macros and
compiler options in the description of _DEFAULT_SOURCE is a little
confusing, and dated, so clarify the situation, and don't assume a
specific value for _DEFAULT_SOURCE.
Also, _DEFAULT_SOURCE is supposed to be defined if none of the C/POSIX
feature test macros are defined, but the condition was lacking a test
for _ISOC11_SOURCE, so that is also addressed.

elf: Remove ad-hoc restrictions on dlopen callers [BZ #22787]
This looks like a post-exploitation hardening measure: If an attacker is
able to redirect execution flow, they could use that to load a DSO which
contains additional code (or perhaps make the stack executable).
However, the checks are not in the correct place to be effective: If
they are performed before the critical operation, an attacker with
sufficient control over execution flow could simply jump directly to
the code which performs the operation, bypassing the check. The check
would have to be executed unconditionally after the operation and
terminate the process in case a caller violation was detected.
Furthermore, in _dl_check_caller, there was a fallback reading global
writable data (GL(dl_rtld_map).l_map_start and
GL(dl_rtld_map).l_text_end), which could conceivably be targeted by an
attacker to disable the check, too.
Other critical functions (such as system) remain completely
unprotected, so the value of these additional checks does not appear
that large. Therefore this commit removes this functionality.

Fix -Os ferror_unlocked linknamespace, localplt issues (bug 15105, bug
19463).
Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for ferror_unlocked.
The usual approach is followed of adding __ferror_unlocked (inlined
when ferror_unlocked is), making calls use it when required for
namespace reasons (only one such call), and using libc_hidden_proto /
libc_hidden_weak for the ferror_unlocked weak alias when only localplt
but not namespace issues are involved.
Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and
localplt test failures are resolved). Because of other such failures
that remain after this patch, neither of the bugs can yet be closed.

Fix posix/tst-glob_lstat_compat on alpha [BZ #22818]
The tst-glob_lstat_compat test needs to run tests on the previous
version of glob. On alpha, there are three versions of glob, GLIBC_2.0,
GLIBC_2.1 and GLIBC_2.27, while on other architectures there are only
the GLIBC_2.0 and GLIBC_2.27 version. Therefore on alpha the previous
version is GLIBC_2.1 and not GLIBC_2.0.
Changelog:
[BZ #22818]

intl/tst-gettext: fix failure with newest msgfmt
Since upstream gettext commit d13f165b83 (msgfmt: Remove
POT-Creation-Date field from the header in the output.), msgfmt does not
copy the POT-Creation-Date field in the header entry from the po file to
the mo file anymore. This breaks the assumption that we can test gettext
by comparing each message in the po files with the corresponding string
return by gettext. This makes the intl/tst-gettext to fail.
While it would have been possible to modify the po2test.awk script to
also strip the line POT-Creation-Date field when creating the msgs.h
file, it would not work with both the old and new msgfmt.
Instead create a tst-gettext-de.po file from de.po by removing the
POT-Creation-Date line. Another alternative would be to use a static
tst-gettext-de.po file, but I guess the reason for using de.po is to
also catch issues caused by newly added strings.
As tst-catgets also uses msg.h, it should also be updated. Instead of
using the new tst-gettext-de.po file, the patch modifies xopen-msg.awk
to avoid creating a second catgets->intl dependency.
Changelog:
[BZ #21508]
* catgets/xopen-msg.awk: Ignore POT-Creation-Date line.
* intl/Makefile ($(objpfx)tst-gettext-de.po): Generate
intl/tst-gettext-de.po from po/de.po by removing the

* intl/tst-gettext.sh: Use ${objpfx}tst-gettext-de.po instead of

Add runtime check if mutex will be elided in tst-mutex8 testcases.
An elided mutex don't fail destroy. Elision was disabled for the
test nptl/tst-mutex8 in nptl/Makefile. Thus we can run tests which
destroy a locked mutex.
As elision is only disabled for tst-mutex8, the variants
tst-mutex8-static, tst-mutexpi8 and tst-mutexpi8-static are still
failing if lock elision is enabled.
This patch adds a runtime check, if the checked type of mutex will
be elided. This check is using TUNABLE_GET_FULL to determine if
elision is enabled via the tunables framework.
The pthread_mutex_destroy tests are only run if we dont't assume an
elided mutex.
This way, we can run the whole glibc testsuite with or without enabled
lock elision.
ChangeLog:
* nptl/Makefile (tst-mutex8-ENV): Delete.
* nptl/tst-mutex8.c (check_type):
Add runtime check if mutex will be elided.

Document use of CC and CFLAGS in more detail (bug 20980, bug 21234).
There are some bug reports from people setting CFLAGS not including a
-O option and then being confused when the build fails. This patch
addresses this by documenting the proper use of CC and CFLAGS in more
detail - saying what options should go where and specifying the
requirement to compile with optimization.
The previous text incorrectly used @var markup with CC and CFLAGS.
The correct markup for environment variables is @env, but it's also
the case that passing such variables explicitly on the configure
command line is preferred to passing them in the environment, so this
patch changes the documentation to describe passing them on the
command line (and uses @code).
In many cases putting options in the wrong place may in fact work, but
I believe what I've specified is the correct rule for which options to
put where.
[BZ #20980]
[BZ #21234]
* manual/install.texi (Configuring and compiling): Describe
passing CC and CFLAGS on configure command line, not as

requirement to compile with optimization.

Fix hppa local PLT entries for sigprocmask (bug 18124).
When adding/updating localplt.data for various architectures to get
the compilation tests passing everywhere, I generally made it reflect
the existing state of what local PLT entries were actually seen,
rather than an ideal state with as few as possible such entries,
mainly for functions that are intended to be interposable.
This patch eliminates some local PLT entries for hppa by using
__sigprocmask instead of sigprocmask in getcontext and setcontext.
The specific case of sigprocmask called by setcontext is the third of
four items in bug 18124 (the other three have already been fixed for
2.26 or earlier releases). Note that hppa-specific localplt.data
entries for __sigsetjmp, _IO_funlockfile and __errno_location remain,
but the causes / fixes are less immediately obvious from source
inspection.
Tested (compilation tests only) with build-many-glibcs.py for
hppa-linux-gnu.

Among other localplt test failures when building with -Os, there are

this patch adds libc_hidden_proto / libc_hidden_def for them to avoid

Use libc_hidden_* for fputs (bug 15105).
Among other localplt test failures when building with -Os, there are
libc.so PLT references for fputs. fputs calls normally get redirected
to _IO_fputs by a macro in include/stdio.h (and _IO_fputs in turn uses
libc_hidden_proto), but GCC can convert an fprintf call with a
constant string argument into an fputs call, which of course is then
unaffected by the macro redirection. (I don't know why this issue
only appears with -Os.)
This patch duly adds a use of libc_hidden_proto for fputs. I see no
obvious reason why the fputs macro redirection is needed at all, but
this patch does not change it.
Tested for x86_64 (both that it removes this particular localplt
failure for -Os - but other such failures remain so the bug can't yet
be closed - and that the testsuite continues to pass without -Os).

Continuing the fixes for linknamespace and localplt test failures with

patch fixes such failures for feof_unlocked.
The usual approach is followed of adding __feof_unlocked (inlined when

reasons, and using libc_hidden_proto / libc_hidden_weak for the

needs to be conditional since that code is also used in nscd (where
__feof_unlocked is not available).

Remove slow paths from pow
Remove the slow paths from pow. Like several other double precision math
functions, pow is exactly rounded. This is not required from math functions
and causes major overheads as it requires multiple fallbacks using higher
precision arithmetic if a result is close to 0.5ULP. Ridiculous slowdowns
of up to 100000x have been reported when the highest precision path
triggers.
All GLIBC math tests pass on AArch64 and x64 (with ULP of pow set to 1).
The worst case error is ~0.506ULP. A simple test over a few hundred million
values shows pow is 10% faster on average. This fixes BZ #13932.

Add narrowing add functions.
This patch adds the narrowing add functions from TS 18661-1 to glibc's
libm: fadd, faddl, daddl, f32addf64, f32addf32x, f32xaddf64 for all
configurations; f32addf64x, f32addf128, f64addf64x, f64addf128,
f32xaddf64x, f32xaddf128, f64xaddf128 for configurations with
_Float64x and _Float128; __nldbl_daddl for ldbl-opt. As discussed for
the build infrastructure patch, tgmath.h support is deliberately
deferred, and FP_FAST_* macros are not applicable without optimized
function implementations.
Function implementations are added for all relevant pairs of formats
(including certain cases of a format and itself where more than one
type has that format). The main implementations use round-to-odd, or
a trivial computation in the case where both formats are the same or
where the wider format is IBM long double (in which case we don't
attempt to be correctly rounding). The sysdeps/ieee754/soft-fp
implementations use soft-fp, and are used automatically for
configurations without exceptions and rounding modes by virtue of
existing Implies files. As previously discussed, optimized versions
for particular architectures are possible, but not included.
i386 gets a special version of f32xaddf64 to avoid problems with
double rounding (similar to the existing fdim version), since this
function must round just once without an intermediate rounding to long
double. (No such special version is needed for any other function,
because the nontrivial functions use round-to-odd, which does the
intermediate computation with the rounding mode set to round-to-zero,
and double rounding is OK except in round-to-nearest mode, so is OK
for that intermediate round-to-zero computation.) mul and div will
need slightly different special versions for i386 (using round-to-odd
on long double instead of precision control) because of the
possibility of inexact intermediate results in the subnormal range for
double.
To reduce duplication among the different function implementations,
math-narrow.h gets macros CHECK_NARROW_ADD, NARROW_ADD_ROUND_TO_ODD
and NARROW_ADD_TRIVIAL.
In the trivial cases and for any architecture-specific optimized
implementations, the overhead of the errno setting might be
significant, but I think that's best handled through compiler built-in
functions rather than providing separate no-errno versions in glibc
(and likewise there are no __*_finite entry points for these function
provided, __*_finite effectively being no-errno versions at present in
most cases).
Tested for x86_64 and x86, with both GCC 6 and GCC 7. Tested for
mips64 (all three ABIs, both hard and soft float) and powerpc with GCC
7. Tested with build-many-glibcs.py with both GCC 6 and GCC 7.

Fix narrowing function tests build for powerpc64le.
Testing narrowing functions with build-many-glibcs.py showed up a
further testsuite fix needed to enable building such functions for
powerpc64le: tests test-<narrower-type>-float128-<function> (and
likewise for float64x) needed the same special handling for
powerpc64le as test-float128-* and test-float64x-*. This patch adds
that special handling.
Tested with build-many-glibcs.py for powerpc64le in conjunction with
the main patch adding narrowing add functions.

When ldconfig reads Elf64 files to determine the ABI, it used the
Elf32 type, so read the wrong location, and stored the wrong ABI

an Elf64 type for Elf64 objects instead.

Handle narrowing function sNaN test disabling based on argument format.
Testing narrowing functions for x86_64 with GCC 6 showed up a further
testsuite fix needed: there is no _Float128 sNaN support before GCC 7
on x86_64 / x86, and the existing tests of SNAN_TESTS only checked it
for the return type, not for the argument type. This patch fixes the
code to check SNAN_TESTS (ARG_FLOAT) as well (in a variable set in
libm-test-driver.c, since libm-test-support.c is compiled only once
for each choice of FLOAT).
Tested for x86_64 and x86 with GCC 6 in conjunction with the main
patch adding narrowing add functions.

Add test infrastructure for narrowing libm functions.
This patch continues preparations for adding TS 18661-1 narrowing libm
functions by adding the required testsuite infrastructure to test such
functions through the libm-test infrastructure.
That infrastructure is based around testing for a single type, FLOAT.
For the narrowing functions, FLOAT, the "main" type for testing, is
the function return type; the argument type is ARG_FLOAT. This is
consistent with how the code built once for each type,
libm-test-support.c, depends on FLOAT for such things as calculating
ulps errors in results but can already handle different argument types
(pointers, integers, long double for nexttoward).
Makefile machinery is added to handle building tests for all pairs of
types for which there are narrowing functions (as with non-narrowing
functions, aliases are tested just the same as the functions they
alias). gen-auto-libm-tests gains a --narrow option for building
outputs for narrowing functions (so narrowing sqrt and fma will share
the same inputs as non-narrowing, but gen-auto-libm-tests will be run
with and without that option to generate different output files). In
the narrowing case, the auto-libm-test-out-narrow-* files include
annotations for each test about what properties ARG_FLOAT must have to
be able to represent all the inputs for that test; those annotations
result in calls to the TEST_COND_arg_fmt macro.
gen-libm-test.pl has some minor updates to handle narrowing tests (for
example, arguments in such tests must be surrounded by ARG_LIT calls
instead of LIT calls). Various new macros are added to the C test
support code (for example, sNaN initializers need to be properly
typed, so arg_snan_value is added; other such arg_* macros are added
as it seems cleanest to do so, though some are not strictly required).
Special-casing of the ibm128 format to allow for its limitations is
adjusted to handle it as the argument format as well as as the result
format; thus, the tests of the new functions allow nonzero ulps only
in the case where ibm128 is the argument format, as otherwise the
functions correspond to fully-defined IEEE operations. The ulps in
question appear as e.g. 'Function: "add_ldouble"' in libm-test-ulps
(with 1ulp errors then listed for double and float for that function
in powerpc); no support is added to generate corresponding faddl /
daddl ulps listings in the ulps table in the manual.
For the previous patch, I noted the need to avoid spurious macro
expansions of identifiers such as "add". A test test-narrow-macros.c
is added to verify such macro expansions are successfully avoided, and
there is also a -mlong-double-64 version of that test for ldbl-opt.
This test is set up to cover the full set of relevant identifiers from
the start rather than adding functions one at a time as each function
group is added.
Tested for x86_64 (this patch in isolation, as well as testing for
various configurations in conjunction with the actual addition of
"add" functions).

Author: Joseph Myers <address@hidden>

Add build infrastructure for narrowing libm functions.
TS 18661-1 defines libm functions that carry out an operation (+ - * /
sqrt fma) on their arguments and return a result rounded to a
(usually) narrower type, as if the original result were computed to
infinite precision and then rounded directly to the result type
without any intermediate rounding to the argument type. For example,
fadd, faddl and daddl for addition. These are the last remaining TS
18661-1 functions left to be added to glibc. TS 18661-3 extends this
to corresponding functions for _FloatN and _FloatNx types.
As functions parametrized by two rather than one varying
floating-point types, these functions require infrastructure in glibc
that was not required for previous libm functions. This patch
provides such infrastructure - excluding test support, and actual
function implementations, which will be in subsequent patches.
Declaring the functions uses a header bits/mathcalls-narrow.h, which
is included many times, for each relevant pair of types. This will
end up containing macro calls of the form
__MATHCALL_NARROW (__MATHCALL_NAME (add), __MATHCALL_REDIR_NAME (add), 2);
for each family of narrowing functions. (The structure of this macro
call, with the calls to __MATHCALL_NAME and __MATHCALL_REDIR_NAME
there rather than in the definition of __MATHCALL_NARROW, arises from
the names such as "add" *not* themselves being reserved identifiers -
meaning it's necessary to avoid any indirection that would result in a
user-defined "add" macro being expanded.) Whereas for existing
functions declaring long double functions is disabled if _LIBC in the
case where they alias double functions, to facilitate defining the
long double functions as aliases of the double ones, there is no such
logic for the narrowing functions in this patch. Rather, the files
defining such functions are expected to use #define to hide the
original declarations of the alias names, to avoid errors about
defining aliases with incompatible types.
math/Makefile support is added for building the functions (listed in
libm-narrow-fns, currently empty) for all relevant pairs of types. An
internal header math-narrow.h is added for macros shared between
multiple function implementations - currently a ROUND_TO_ODD macro to
facilitate writing functions using the round-to-odd implementation
approach, and alias macros to create all the required function
aliases. libc_feholdexcept_setroundf128 and libc_feupdateenv_testf128
are added for use when required (only for x86_64). float128_private.h
support is added for ldbl-128 narrowing functions to be used for
_Float128.
Certain things are specifically omitted from this patch and the
immediate followups. tgmath.h support is deferred; there remain
unresolved questions about how the type-generic macros for these
functions are supposed to work, especially in the case of arguments of
integer type. The math.h / bits/mathcalls-narrow.h logic, and the
logic for determining what functions / aliases to define, will need
some adjustments to support the sqrt and fma functions, where
e.g. f32xsqrtf64 can just be an alias for sqrt rather than a separate
function. TS 18661-1 defines FP_FAST_* macros but no support is
included for defining them (they won't in general be true without
architecture-specific optimized function versions).
For each of the function groups (add sub mul div sqrt fma) there are
always six functions present (e.g. fadd, faddl, daddl, f32addf64,
f32addf32x, f32xaddf64). When _Float64x and _Float128 are supported,
there are seven more (e.g. f32addf64x, f32addf128, f64addf64x,
f64addf128, f32xaddf64x, f32xaddf128, f64xaddf128). In addition, in
the ldbl-opt case there are function names such as __nldbl_daddl (an
alias for f32xaddf64, which is not a reserved name in TS 18661-1, only
in TS 18661-3), for calls to daddl to be mapped to in the
-mlong-double-64 case. (Calls to faddl just get mapped to fadd, and
for sqrt and fma there won't be __nldbl_* functions because dsqrtl and
dfmal can just be mapped to sqrt and fma with -mlong-double-64.)
While there are six or thirteen functions present in each group (plus
__nldbl_* names only as an ABI, not an API), not all are distinct;
they fall in various groups of aliases. There are two distinct
versions built if long double has the same format as double; four if
they have distinct formats but there is no _Float64x or _Float128
support; five if long double has binary128 format; seven when
_Float128 is distinct from long double.
Architecture-specific optimized versions are possible, but not
included in my patches. For example, IA64 generally supports
narrowing the result of most floating-point instructions; Power ISA
2.07 (POWER8) supports double values as arguments to float
instructions, with the results narrowed as expected; Power ISA 3
(POWER9) supports round-to-odd for float128 instructions, so meaning
that approach can be used without needing to set and restore the
rounding mode and test "inexact". I intend to leave any such
optimized versions to the architecture maintainers. Generally in such
cases it would also make sense for calls to these functions to be
expanded inline (given -fno-math-errno); I put a suggestion for TS
18661-1 built-in functions at <https://gcc.gnu.org/wiki/SummerOfCode>.

Define char16_t, char32_t consistently with uint_least16_t, uint_least32_t
(bug 17979).
As noted in bug 17979 (and as I noted earlier in
<https://sourceware.org/ml/libc-alpha/2012-02/msg00647.html>), uchar.h
has gratuitously complicated code to determine the types for char16_t
and char32_t, and to reject including that header for pre-C11
compilers not defining __CHAR16_TYPE__ and __CHAR32_TYPE__. Since
those types are always required to match uint_least16_t and
uint_least32_t, which glibc knows how to define without reference to
such predefined macros, it's safe just to define those types the same
as the *least* types are defined in stdint.h, so allowing the header
to work with (for example) GCC 4.3.
This patch implements that. bits/types.h is made to define
__int_leastN_t and __uint_leastN_t so the logic for those types can
stay in a single place, and stdint.h is made to use those __*_t to
define the public *_t types. uchar.h is then made to use
__uint_least16_t and __uint_least32_t to define char16_t and char32_t,
so simplifying the logic there. A new test is added that verifies the
types chosen for char16_t and char32_t do indeed match the types the
compiler uses for u"" and U"" string literals.
Tested for x86_64. (I have not tested with any of the older compilers
for which this would actually make a difference to whether you can
include uchar.h.)

Post-cleanup 2: minimize _G_config.h.
Nearly everything in _G_config.h is either junk or more appropriately
defined elsewhere:
* _G_fpos_t, _G_fpos64_t, and _G_BUFSIZ are already completely unused.
* All remaining uses of _G_va_list have been changed to __gnuc_va_list.
* The definition of _G_HAVE_ST_BLKSIZE/_IO_HAVE_ST_BLKSIZE has
been inlined into its sole use.
* The complete definition of _G_iconv_t has been moved to libio.h and
renamed _IO_iconv_t (all actual users used that name).
* _G_IO_IO_FILE_VERSION is vestigial; some code cares whether
_IO_stdin_used exists, but nothing looks at its value. I've
preserved the value as a hardwired constant in csu/init.c.
This means csu/init.c no longer needs to include anything.
* Many of the headers included by _G_config.h were already being
included directly by either either libio.h or stdio.h; the
remaining ones were moved to libio.h.
* _G_HAVE_MREMAP is still relevant, because mremap genuinely is a
Linux extension; it's not in POSIX and as far as I can tell it's
not available on the Hurd either. I also preserved _G_HAVE_MMAP,
since it's conceivable someone would want to port glibc to a
MMU-less, mmap-less environment in the future. Both are now always
defined to 1/0 as is the current convention, instead of the older
1/undef convention. These are the only symbols still defined in
_G_config.h.
* The actual inclusion of _G_config.h moves from libio.h to libioP.h,
as this is where a potential override of _G_HAVE_MMAP happens.
* The #ifdef logic in libioP.h controlling _IO_JUMPS_OFFSET has been
simplified.
After this patch, the only surviving _G_ symbols are the struct tag
names _G_fpos_t and _G_fpos64_t, which are preserved for the sake of
C++ mangled names in applications, and _G_HAVE_MMAP and _G_HAVE_MREMAP,
which do not seem worth renaming.
Installed stripped libraries are unchanged by this patch.
* bits/_G_config.h: Move back to sysdeps/generic/_G_config.h.
Delete all contents except for definitions of _G_HAVE_MMAP and
_G_HAVE_MREMAP. Add commentary explaining those two symbols.
* sysdeps/unix/sysv/linux/bits/_G_config.h: Move back to
sysdeps/unix/sysv/linux/_G_config.h. Make same content
change as above.
* libio/libio.h: Don't include bits/_G_config.h here.
Include stddef.h with __need_wchar_t defined. Include
bits/types/__mbstate_t.h, bits/types/wint_t.h, and gconv.h.
Define _IO_iconv_t here, directly.
Don't define _IO_HAVE_ST_BLKSIZE.
* libio/libioP.h: Include _G_config.h here. Move include of
shlib-compat.h up with rest of includes. Simplify conditionals
controlling definition of _IO_JUMPS_OFFSET.
* csu/init.c: Remove always-true #if around entire file.
Don't include stdio.h. Set _IO_stdin_used to hardwired
constant 0x20001, and update commentary.
* include/stdio.h, sysdeps/ieee754/ldbl-opt/nldbl-compat.h:
Replace all uses of _G_va_list with __gnuc_va_list.
* libio/filedoalloc.c: Use #if defined _STATBUF_ST_BLKSIZE
instead of #if _IO_HAVE_ST_BLKSIZE.
* libio/fileops.c: Test _G_HAVE_MREMAP with #if, not #ifdef.
* libio/iofdopen.c, libio/iofopen.c: Test _G_HAVE_MMAP with #if,
not #ifdef.

Post-cleanup 1: move libio.h back out of bits/.
We can't go very far with libio cleanups as long as we still have
_IO_MTSAFE_IO, and I am not tackling that in this patch series,
but we can at least make the maze of stdio-related headers a
little less complicated.
In this patch, libio.h moves back out of bits/ into the top level of
the libio subdirectory, and is merged with libio/bits/libio-ldbl.h
(which also used to be installed) and include/libio.h. Since almost
no files include libio.h directly, this is quite straightforward.
libio.h is now always used with _LIBC defined, so all of the _LIBC ||
_GLIBCPP_USE_WCHAR_T conditionals are unnecessary. Similarly, the
ifdef nest surrounding the definition of _IO_fwide_maybe_incompatible
can collapse down to a single SHLIB_COMPAT check. I also took the
opportunity to add some checks for configuration botches to libio.h.
Installed stripped libraries are unchanged by this patch.
* libio/bits/libio.h: Move back to libio/libio.h and adjust
multiple-include guard to match.
Merge contents of libio/bits/libio-ldbl.h and include/libio.h
into this file.
Remove preprocessor conditionals that are always true and/or
redundant to other preprocessor conditionals in the same nest.
Include shlib-compat.h unconditionally.
Error out if _LIBC is not defined, or if _ISOMAC is defined,
or if _IO_MTSAFE_IO is defined but _IO_lock_t_defined is not
defined after including stdio.h.
Use __BEGIN_DECLS/__END_DECLS.
* libio/bits/libio-ldbl.h, include/bits/libio.h: Delete file.
* include/stdio.h, libio/iolibio.h, libio/libioP.h: Include
libio.h as <libio/libio.h> rather than as <bits/libio.h>.

Don't install libio.h or _G_config.h.
We shipped 2.27 with libio.h and _G_config.h still installed but
issuing warnings when used. Let's stop installing them early in 2.28
so that we have plenty of time to think of another plan if there are
problems.
The public stdio.h had a genuine dependency on libio.h for the
complete definitions of FILE and cookie_io_functions_t, and a genuine
dependency on _G_config.h for the complete definitions of fpos_t and
fpos64_t; these are moved to single-type headers.
bits/types/struct_FILE.h also provides a handful of accessor and
bitflags macros so that code is not duplicated between bits/stdio.h
and libio.h. All the other _IO_ and _G_ names used by the public
stdio.h can be replaced with either public names or __-names.
In order to minimize the risk of breaking our own compatibility code,
bits/types/struct_FILE.h preserves the _IO_USE_OLD_IO_FILE mechanism
exactly as it was in libio.h, but you have to define _LIBC to use it,
or it'll error out. Similarly, _IO_lock_t_defined is preserved
exactly, but will error out if used without defining _LIBC.
Internally, include/stdio.h continues to include libio.h, and libio.h
scrupulously provides every _IO_* and _G_* name that it always did,
perhaps now defined in terms of the public names. This is how this
patch avoids touching dozens of files throughout glibc and becoming
entangled with the _IO_MTSAFE_IO mess. The remaining patches in this
series eliminate most of the _G_ names.
Tested on x86_64-linux; in addition to the test suite, I installed the
library in a sysroot and verified that a simple program that uses
stdio.h could be compiled against the installed library, and I also
verified that installed stripped libraries are unchanged.

Fix -Os gnu_dev_* linknamespace, localplt issues (bug 15105, bug 19463).
Building with -Os produces linknamespace and localplt failures for,
among other functions, gnu_dev_major, gnu_dev_minor and
gnu_dev_makedev.
The issue is that those functions are not inlined when building with
-Os. While one could force them to be inlined in that case, it seems
more natural to fix this issue similarly to other namespace issues.
Thus, this patch makes gnu_dev_* into weak aliases for hidden symbols
__gnu_dev_*; __gnu_dev_* are then defined as inlines in the internal
include/sys/sysmacros.h, and uses of gnu_dev_* (often via the macros
major, minor and makedev) for which there are namespace issues are
changed to use __gnu_dev_*; where there are no namespace issues, use
of libc_hidden_proto serves to avoid unnecessary local PLT entry use.
Tested for x86_64, (a) without -Os, to verify the testsuite continues
to pass without problems and that the functions called under their new
names continue to be inlined as expected in that case; (b) with -Os,
to verify that the linknamespace and localplt failures in question go
away (but because of other such failures present, neither of the
relevant bugs can yet be closed).

Fix -Os strcoll, wcscoll, build (bug 21313).
The findidx functions used in implementing strcoll / wcscoll already
use DIAG_IGNORE_Os_NEEDS_COMMENT for spurious -Wmaybe-uninitialized
warnings that appear with -Os. In building with GCC 7 for x86_64 with
-Os, I find there are additional such warnings, for the same structure
elements, which are spurious for the same reasons given in the
existing comments (and this was also reported for MIPS with GCC 5 in
bug 21313). This patch adds corresponding uses of DIAG_* in the
places that get the additional warnings.
Tested for x86_64 with -Os that this eliminates those warnings and so
allows the build to progress further.

Remove slow paths from log
Remove the slow paths from log. Like several other double precision math
functions, log is exactly rounded. This is not required from math functions
and causes major overheads as it requires multiple fallbacks using higher
precision arithmetic if a result is close to 0.5ULP. Ridiculous slowdowns
of up to 100000x have been reported when the highest precision path
triggers.
Interestingly removing the slow paths makes hardly any difference in
practice:
the worst case error is still ~0.502ULP, and exp(log(x)) shows identical
results
before/after on many millions of random cases. All GLIBC math tests pass on
AArch64 and x64 with no change in ULP error. A simple test over a few
hundred
million values shows log is now 18% faster on average.

Linux: use reserved name __key in pkey_get [BZ #22797]
_key is not reserved name and we should avoid using that. It seems that
it was simple typo when pkey_* was implemented.

Unify and simplify bits/byteswap.h, bits/byteswap-16.h headers (bug 14508,
bug 15512, bug 17082, bug 20530).
We have a general principle of preferring optimizations for library
facilities to use compiler built-in functions rather than being
located in library headers, where the compiler can reasonably optimize
code without needing to know glibc implementation details.
This patch applies this principle to bits/byteswap.h, eliminating all
the architecture-specific variants and bits/byteswap-16.h. The
__bswap_16, __bswap_32 and __bswap_64 interfaces all become inline
functions, never macros, using the GCC built-in functions where
available and otherwise a single architecture-independent definition
using shifts and masking (which compilers may well be able to detect
and optimize; GCC has detection of various byte-swapping idioms).
The __bswap_constant_32 macro needs to stay around because of uses in
static initializers within glibc and its tests, and so for consistency
all __bswap_constant_* are kept rather than just being inlined into
the old-GCC-or-non-GCC parts of the __bswap_* inline function
definitions.
Various open bugs are addressed by this cleanup, with caveats about
exactly what is covered by those bugs and when the bugs applied at
all.
Bug 14508 reports -Wformat warnings building glibc because __bswap_*
sometimes returned the wrong types. Obviously we already don't have
such warnings any more or the build would be failing, given -Werror,
and I suspect that bug was originally for wrong types for x86_64, as
fixed by commit d394eb742a3565d7fe7a4b02710a60b5f219ee64 (glibc 2.17).
The only case I saw removed by this patch where the types would still
have been wrong was the non-__GNUC__ case of __bswap_64 in the s390
header (using unsigned long long int, but uint64_t would be unsigned
long int for 64-bit). In any case, the single header consistently
uses __uintN_t types after this patch, thereby eliminating all such
bugs. The existing string/test-endian-types.c test already suffices
to verify that the types are correct with the compiler used to build
glibc and its tests.
Bug 15512 reports an error from __bswap_constant_16 with -Werror
-Wsign-conversion. I am unable to reproduce this with any GCC version
supporting -Wsign-conversion - all seem to be able to avoid warning
for ((x) >> 8) & 0xffu, where x is uint16_t, which while it formally
does involve an implicit conversion from int to unsigned int, is also
a case where it should be easy for the compiler to see that the value
converted is never negative. But in this patch __bswap_constant_16 is
changed to use signed 0xff so that no such implicit conversion occurs
at all, and a test with -Werror -Wsign-conversion is added.
Bug 17082 objects to the use of ({}) statement expressions in these
macros preventing use at file scope (in C, that's in sizeof etc.; in
C++, more generally in static initializers). The particular case of
these interfaces is fixed by this patch as it changes them to inline
functions, eliminating all uses of ({}) in bits/byteswap.h, and a
corresponding testcase is added. The bug tries to raise a more
general policy question about use of ({}) in macros in installed
headers, referring to "many other libc functions" (unspecified which
functions are being considered).
Since such policy questions belong on libc-alpha, and since there
*are* macros in installed headers which can't really avoid using ({})
(where they are type-generic, so can't use an inline function, but
need a temporary variable, and a few where the interface involves
returning memory from alloca so can't use an inline function either),
I propose to consider that bug fixed with this change. That is
without prejudice to any other new bugs anyone wishes to file *for
precisely defined sets of macros* requesting moving away from ({})
*where it is clearly possible for those interfaces*. Where ({}) can
be avoided, typically by use of an inline function, I think that's a
good idea - that inline functions are typically to be preferred to
({}) for header interfaces where such optimizations are useful but the
interface is suited to being defined using an inline function.
Bug 20530 requests use of __builtin_bswap16 when available (GCC 4.8
and later), which this patch implements.
Tested for x86_64, and with build-many-glibcs.py. Also did an x86_64
test with the __GNUC_PREREQ conditionals changed to "#if 0" to verify
the old-GCC/non-GCC case in the headers. (There are already existing
tests for correctness of results of these interfaces.)

Correct type of SSIZE_MAX for 32-bit (bug 13575).
Bug 13575 reports that SSIZE_MAX is wrongly defined as LONG_MAX on
32-bit systems where ssize_t is defined as int (which is most 32-bit
systems supported by glibc).
This patch fixes the definition, using a conditional on
__WORDSIZE32_SIZE_ULONG to determine the appropriate type in the
32-bit case. Formally ssize_t need not be the signed type
corresponding to size_t, but as it is for all current glibc
configurations, there is no need for a new macro different from the
one used for defining SIZE_MAX. A testcase is added for both the type
and the value of SSIZE_MAX.
There is a relevant peculiarity in
sysdeps/unix/sysv/linux/s390/bits/typesizes.h:
/* Compatibility with g++ 2.95.x. */
/* size_t is unsigned long int on s390 -m31. */
This has the effect that for GCC 2 for s390, ssize_t does not match
__WORDSIZE32_SIZE_ULONG. I don't think such a conditional on the GCC
version makes sense - to have a well-defined ABI, the choices of
standard types should not depend on the GCC version. It's also the
case that upstream GCC 2.95 did not support s390, and glibc headers
don't in general try to support past development GCC versions - only
actual releases and current mainline development. But whether or not
that GCC 2 case should be removed (with or without a NEWS entry for
such a change), this patch does not result in any changes for s390;
the value is always still LONG_MAX in the s390 case because
__WORDSIZE32_SIZE_ULONG is always defined for 32-bit s390. I don't
think any such oddity in code only active for unofficial or unreleased
old compiler versions should block closing the present bug as fixed
once this patch is in.
Tested for x86_64 and x86, and with build-many-glibcs.py.

Use xmalloc in tst-setcontext-fpscr.c (bug 19668).
Bug 19668 reports an unchecked malloc call in the test
sysdeps/powerpc/fpu/tst-setcontext-fpscr.c. This patch makes that
test use xmalloc. It does not otherwise move this test to the
support/ infrastructure or support/test-driver.c; the test has various
uses of exit and _exit on error cases, and uses atexit, and while I
think those things would all still work in the context of
test-driver.c, it's not an immediately obvious conversion the way it
would be for many tests that don't use test-driver.c.

Only define loff_t for __USE_MISC (bug 14553).
Bug 14553 reports that sys/types.h defines loff_t unconditionally,
despite it not being part of any supported standard. This is
permitted by the POSIX *_t reservation, but as a
quality-of-implementation issue it's still best not to define it
except for __USE_MISC. This patch conditions the definition
accordingly, updating a macro in sysdeps/unix/sysv/linux/sys/quota.h
to use __loff_t so it still works even if __USE_MISC is not defined.
codesearch.debian.net suggests there are quite a lot of loff_t uses
outside glibc, but it might well make sense to change all (few) uses
of loff_t or __loff_t inside glibc to use off64_t or __off64_t
instead, leaving only the definitions, treating this name as
obsolescent.
Tested for x86_64.

Remove getc and putc macros from the public stdio.h.
The getc and putc macros in the public stdio.h expand to call _IO_getc
and _IO_putc respectively. As _IO_getc, fgetc, and getc are all aliases
for the same function, and _IO_putc, fputc, and putc are also all aliases
for the same function, the macros are pointless. The C standard does
not require getc and putc to be macros, so let's just not have macros.
All four symbols are exported from libc.so at the same, ancient symbol
version, so there should be no risks for binary compatibility. Similarly,
the getchar and putchar inlines in bits/stdio.h forward to getc and putc
instead of their _IO_ aliases.
As a change from longstanding historical practice, this does seem
like it might break _something_, so there is a note in NEWS, which
is also a convenient place to advise people that if they thought getc
and putc had reduced per-character overhead they should consider using
getc_unlocked and putc_unlocked instead. (These are also not macros,
but when optimizing, they are inlines.)
* libio/stdio.h: Don't define getc or putc as macros.
* libio/bits/stdio.h (getchar, putchar): Use getc and putc,
not _IO_getc and _IO_putc.

Add elf.h NT_* macros from Linux 4.15 (bug 14890).
Linux 4.15 adds NT_S390_RI_CB to linux/elf.h (and NT_ARM_SVE, which we
already have in glibc). This shows up that various other ELF note
values from linux/elf.h are missing from glibc's elf.h.
This patch adds the missing values that are relevant to glibc
architectures. As elf.h is a general description of the ELF format,
not necessarily limited to glibc configurations, there's an argument
for having the remaining NT_* values that Linux uses for non-glibc
architectures in glibc's elf.h as well, but this patch does not add
them.
Adding the NT_PRFPREG name is bug 14890. That bug also requests
making the NT_FPREGSET name obsolete. Given that elf.h is not just
for Linux but can describe ELF for other operating systems, I don't
think that a change of name in the Linux kernel is sufficient
justification for declaring the other name obsolete; there can be
multiple names for the same note value, even with incompatible
semantics, if those reflect variants of the ELF format in actual use.
For example, FreeBSD appears still to have the name NT_FPREGSET
<https://github.com/freebsd/freebsd/blob/master/sys/sys/elf_common.h>
(note: I haven't checked whether the FreeBSD kernel actually generates
such notes or whether this is actually an other-OS definition present
in FreeBSD's header).

Add MAP_SYNC from Linux 4.15.
This patch adds the MAP_SYNC macro from Linux 4.15 to various

architectures: in Linux 4.15, this macro is only in
asm-generic/mman.h, and only some architectures' asm/mman.h include
the asm-generic file - the architectures not using the asm-generic
file will need their own values of MAP_SYNC allocated to support this
functionality (some of them also already have conflicting mmap flags
so the value there will have to be different from the generic
0x80000). Specifically, for glibc architectures, alpha hppa mips

This patch updates sysdeps/unix/sysv/linux/syscall-names.list for
Linux 4.15. There only appears to be one new syscall to add to the
list. (The riscv_flush_icache syscall is *not* added because for
whatever reason it doesn't appear in the uapi asm/unistd.h; only in
arch/riscv/include/uapi/asm/syscalls.h, which is only included by the
non-uapi asm/unistd.h - and only syscalls whose __NR_* macros are

Move LDBL_CLASSIFY_COMPAT to its own header.
The general rule in glibc is that it's better for a macro to be always
defined, and tested with #if, than for it to be tested with #ifdef,
because the latter is prone to typos in the macro name as well as to
the header with the macro accidentally not being included in a file
testing it. (Testing with an "if" statement is even better, in those
cases where it's possible to do things that way, as it then means both
cases in the code get checked for syntax in glibc builds with either
value of the condition.)
math_private.h has several different groups of macros, meaning that
architectures wanting to override some of them need to define those
then include the generic version, which then defines macros if not
already defined. It's hard to avoid that arrangement completely, but
various cases can be improved by splitting out macros or groups of
macros into separate files.
This patch splits out the LDBL_CLASSIFY_COMPAT macro into a separate
ldbl-classify-compat.h header. This macro is tested with #ifdef; this
patch changes it to testing with #if, with a default definition to 0
in the generic header and then architecture-specific headers defining
it to 1.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by the patch.

Remove some math_private.h libc_feholdexcept_setround overrides.
math_private.h headers for configurations lacking support for
floating-point exceptions and rounding modes define
libc_feholdexcept_setround to override the default version with one
that discards its rounding mode argument.
Unlike other such libc_fe* macros that I removed, this one is actually
used for such configurations (in dbl-64/e_sqrt.c). However, this does
not make the macro required. It's only used for such configurations
with FE_TONEAREST as the rounding mode (anything needing another mode
should not be used when that mode is unavailable), and the default
definition just calls __feholdexcept and __fesetround. Since we now
have suitable inline do-nothing definitions of __feholdexcept and
__fesetround for the cases of no exceptions and rounding modes, we can
just rely on those inlines to achieve the same optimization as this
macro definition. Thus, this patch removes those macro definitions
(and the math_private.h headers containing them, when no longer needed
after that removal).
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by the patch.

Remove some math_private.h libc_fe* overrides.
math_private.h headers for configurations lacking support for
floating-point exceptions and rounding modes define various libc_fe*
macros to override the default versions with ones that discard any
exception or rounding mode arguments.
Three of the four macros defined in these headers are no longer needed
there: those macros are only used in fma implementations that are not
used for such configurations, now all those configurations properly
use soft-fp fma implementations instead. (Effectively, those macros
were a workaround to allow glibc to build in the absence of a proper
fma implementation for this case - now there is such an
implementation, there is no need to support building the wrong
implementation for those configurations.) Thus, this patch removes
the unnecessary macros.
Tested with build-many-glibcs.py that installed stripped shared

Continuing the process of improving and cleaning up the handling of
configurations lacking support for floating-point exceptions and
rounding modes, this patch adds trivial inline definitions of
feholdexcept and __feholdexcept to the set of inlines for such
configurations in math_private.h. These inlines were missing from the
tile version used as a basis for the previous inlines, despite a few
such function calls ending up in libm.so.
Tested with build-many-glibcs.py. As expected, installed stripped
shared libraries are unchanged for architectures supporting exceptions
and rounding modes, but changed for architectures lacking such
support.

Move fenv.h override inline functions to generic math_private.h.
The tile version of math_private.h defines some inline functions for
fenv.h functions, to optimize away internal calls to these functions
that do nothing given no support for floating-point exceptions and
rounding modes. (Some functions may have error cases for invalid
arguments, but those aren't applicable to the internal calls from
within glibc.) Other configurations lacking support for exceptions
and rounding modes lack such inline functions. This patch moves them
to the generic math_private.h, appropriately conditioned, so that all
such configurations can benefit from the.
include/fenv.h is made to check whether there are any non-default
rounding modes; that needs to be done there, rather than later,
because get-rounding-mode.h defines values for otherwise unsupported
FE_* rounding modes. It also gives an error for FE_TONEAREST
undefined, a case that already did not work for building the glibc
testsuite; the convention has by now been established that all
architectures need to provide a version of bits/fenv.h that at least
defines FE_TONEAREST.
Tested with build-many-glibcs.py. As expected, installed stripped
shared libraries are unchanged for tile and for architectures
supporting exceptions and rounding modes, but changed for non-tile
architectures not supporting exceptions and rounding modes that
previously lacked this optimization (e.g. Nios II libm.so is about 1kB
smaller).
The optimization is not in fact complete (does not cover feholdexcept
/ __feholdexcept, so a few calls to those remain unnecessarily within
libm even after this patch), but that can be dealt with separately.

Move some fenv.h override macros to generic math_private.h.
Various configurations lacking support for floating-point exceptions
and rounding modes have a math_private.h that overrides certain
functions and macros, internal and external, to avoid references to
FE_* constants that are undefined in those configurations. For
example, there are unconditional feraiseexcept (FE_INVALID) calls in
generic libm code, and these macro definitions duly define
feraiseexcept to ignore its argument to avoid an error from FE_INVALID
being undefined.
In fact it is easy to tell in an architecture-independent way whether
this is needed, by testing whether FE_ALL_EXCEPT == 0. Thus, this
patch puts such a test, and feraiseexcept and __feraiseexcept macros,
in the generic math_private.h, so reducing the duplication between
architecture versions of this header. The feclearexcept macro present
in several versions of this header, and fetestexcept in the tile
version, are not needed; they would have been needed before there were
proper soft-fp fma implementations (when generic versions, that depend
on FE_TOWARDZERO and FE_INEXACT, were being used for configurations
not supporting those features), but aren't needed any more, and so are
removed.
The tile version of this header has several inline functions for
fenv.h functions to optimize calls to them away in such configurations
where they do nothing useful, and all these header versions also have
definitions of some of the libc_fe* internal macros. I intend to make
those generic in subsequent patches.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by this patch.

Add ColdFire math-tests.h.
Since I've been fixing build issues for ColdFire, this patch adds a
math-tests.h file for ColdFire, reflecting the lack of support for
exceptions and rounding modes for soft float. I think it is logically

hard and soft float.

Fix m68k bits/fenv.h for no-FPU ColdFire.
The m68k bits/fenv.h is in sysdeps/m68k/fpu/, meaning that no-FPU
ColdFire instead gets the generic (top-level) bits/fenv.h.
That top-level bits/fenv.h defines no rounding mode constants. That
no longer works for building glibc tests: some tests fail to build (at
least with warnings) if no rounding mode macros are defined, so at
least FE_TONEAREST must be defined in all cases (as various
architectures without rounding mode support indeed do), while
__FE_UNDEFINED must be defined in the case where not all the standard
rounding modes are supported.
On general principles of supporting multilib toolchains with a single
set of headers shared between multilibs for a given architecture, it's
also desirable for the same bits/fenv.h header to work for both FPU
and no-FPU configurations. Thus, this patch moves the m68k
bits/fenv.h to sysdeps/m68k/bits/fenv.h, and inserts appropriate
conditionals to handle the no-FPU case. All the exception macros, and
FE_NOMASK_ENV, are disabled in the no-FPU case; FE_ALL_EXCEPT is
defined to 0 in that case. All rounding modes except FE_TONEAREST are
disabled in that case, and __FE_UNDEFINED is defined accordingly. To
avoid an unnecessary ABI change, fenv_t is defined in the no-FPU case
to match the definition it would have got from the generic
bits/fenv.h.
This suffices to get a clean glibc and testsuite build for this
configuration with build-many-glibcs.py (and keeps a clean build for
the other m68k configurations); it has not been otherwise tested.

Do not use packed structures in soft-fp.
Building for soft-float ColdFire produces an error in soft-fp:
In file included from ../sysdeps/ieee754/soft-fp/s_fmaf.c:42:
../soft-fp/single.h:85:3: error: 'packed' attribute ignored for field of
type 'struct <anonymous>' [-Werror=attributes]
} bits __attribute__ ((packed));
^
While this error only appears in that particular case, this attribute
is in fact never useful, on any architecture. If you have
struct __attribute__ ((packed)) { ... } bits;
or
struct { ... } __attribute__ ((packed)) bits;
then the attribute affects the layout of the structure type. But with
the form used in this code
struct { ... } bits __attribute__ ((packed));
the field bits is being declared packed, but the layout of its type
has already been determined at that point. If on any platform the
layout of the sequence of bit-fields were wrong without the use of a
packed attribute, the attribute would need to be used via a definition
of _FP_STRUCT_LAYOUT, not in its present position.
So this patch removes the useless attribute to fix the build for
ColdFire soft-float. Tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by the patch.

Fix -Os log1p, log1pf build (bug 21314).
As reported in bug 21314, building log1p and log1pf fails with -Os
because of a spurious -Wmaybe-uninitialized warning (reported there
for GCC 5 for MIPS, I see it also with GCC 7 for x86_64). This patch,
based on the patches in the bug, fixes this using the DIAG_* macros.
Tested for x86_64 with -Os that this eliminates those warnings and so
allows the build to progress further.

stdlib: Fixing test-*atexit*-race tests on ia64
These tests require a new thread stack size set to a value (0x20000)
lower than the architecture minimum (0x30000). Set the stack size
to PTHREAD_STACK_MIN in this case.
Checked on ia64-linux-gnu.
* stdlib/test-atexit-race-common.c (do_test): Check stack size
against PTHREAD_STACK_MIN.

RISC-V: Build Infastructure
This patch lays out the top-level orginazition of the RISC-V port. It
contains all the Implies files as well as various other fragments of
build infastructure for the RISC-V port. This contains the only change
to a shared file: config.h.in.
RISC-V is a family of base ISAs with optional extensions. The base ISAs
are RV32I and RV64I, which are 32-bit and 64-bit integer-only ISAs, but
this port currently only supports RV64I based systems. Support for
RISC-V lives in in sysdeps/riscv. In addition to these ISAs, our glibc
port supports most of the currently-defined extensions: the A extension
for atomics, the M extension for multiplication, the C extension for
compressed instructions, and the F/D extensions for single/double
precision IEEE floating-point. Most of these extensions are handled by
GCC, but glibc defines various floating-point wrappers and emulation
routines as well as some atomic wrappers.
We support running glibc-based programs on Linux, the support for which
lives in sysdeps/unix/sysv/linux/riscv.

RISC-V: Hard Float Support
This patch contains hardware floating-point support for the RISC-V ISA.
While we currently only support hard-float systems with both the F and D
extensions, I've left the F-specific code split out into seperate
folders in order to ease adding support for F-only and RV32I-based
systems in the future. I gave this a quick once-over and believe I've
removed all the code that implements RV32IF, RV32IFD, and RV64IF
targets.

RISC-V: Generic <math.h> and soft-fp Routines
This patch contains the miscellaneous math routines and headers we have
implemented for RISC-V. This includes things from <math.h> that aren't
completely ISA-generic, floating-point bit manipulation, and soft-fp
hooks.

RISC-V: Thread-Local Storage Support
This patch implements TLS support for RISC-V. We support all four
standard TLS addressing modes (LE, IE, LD, and GD) when running on
Linux via NPTL. There is a draft psABI document that defines our TLS
ABI here

RISC-V: ABI Implementation
This patch contains code that needs to directly know about the RISC-V
ABI, which is specified in a work-in-progress psABI document:
https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md
This is meant to contain all the RISC-V code that needs to explicitly
name registers or manage in-memory structure layout. This does not
contain any of the Linux-specific code.

possible.

sysdeps/init_array: Add PREINIT_FUNCTION to crti.S
The RISC-V port contains a crti.S that simply contains a link to
PREINIT_FUNCTION (when defined). As this should be entirely generic,
Joseph Myers suggested that we update the generic init_array version to
contain this. Since RISC-V is the only user of init_array this won't
break any existing ports.

Make build-many-glibcs.py clean git source directories.
With the git checkouts of Hurd components in build-many-glibcs.py
involving running autoreconf, there's a risk that generated files
could be left behind by an old autoreconf run (if an old version of
the sources generates those files in the source directory but a new
version does not).
This patch avoids that by using git clean -dxfq when updating git
checkouts. In this patch, that's conditional on --replace-sources, to
avoid removing any local not-checked-in files someone may have in
their checkout unless the option has been specifically passed that
says it's OK to blow old checkouts away, complete with any local
changes to them.
* scripts/build-many-glibcs.py (Context.git_checkout): Use git
clean -dxfq for git updates when replacing sources.

Clean up build-many-glibcs.py libcilkrts disabling.
The disabling of libcilkrts in build-many-glibcs.py has some
peculiarities. It's only for the final GCC build, not the initial
bootstrap one, whereas normally anything disabled for the final build
should be disabled for the bootstrap one as well. And it's only for
Hurd, when it's more natural by analogy with the libsanitizer
disabling to disable this library unconditionally, not only for
targets where it's known to break. This patch cleans up that
disabling accordingly, adding a comment so it's obvious it can be
removed once GCC 7 is too old to build glibc.
* scripts/build-many-glibcs.py (Config.build_gcc): Use
--disable-libcilkrts unconditionally, not just for the final GCC
build for Hurd.

Revert Intel CET changes to __jmp_buf_tag (Bug 22743)
In commit cba595c350e52194e10c0006732e1991e3d0803b and commit
f81ddabffd76ac9dd600b02adbf3e1dac4bb10ec, ABI compatibility with
applications was broken by increasing the size of the on-stack
allocated __pthread_unwind_buf_t beyond the oringal size.
Applications only have the origianl space available for
__pthread_unwind_register, and __pthread_unwind_next to use,
any increase in the size of __pthread_unwind_buf_t causes these
functions to write beyond the original structure into other
on-stack variables leading to segmentation faults in common
applications like vlc. The only workaround is to version those
functions which operate on the old sized objects, but this must
happen in glibc 2.28.
Thank you to Andrew Senkevich, H.J. Lu, and Aurelien Jarno, for
submitting reports and tracking the issue down.
The commit reverts the above mentioned commits and testing on
x86_64 shows that the ABI compatibility is restored. A tst-cleanup1
regression test linked with an older glibc now passes when run
with the newly built glibc. Previously a tst-cleanup1 linked with
an older glibc would segfault when run with an affected glibc build.
Tested on x86_64 with no regressions.

Add soft-float ColdFire to build-many-glibcs.py.
Since it turns out soft-float ColdFire has a different glibc ABI to
hard-float ColdFire, as well as various differences in which glibc
code gets built, this patch adds such a configuration to
build-many-glibcs.py to (hopefully) complete the set of ABIs being
tested. (Note that the build for soft-float ColdFire is currently
broken even with GCC mainline - I have a glibc patch to fix this, but
it needs before-and-after build-many-glibcs.py comparison of stripped
binaries for all configurations before being committed.)
* scripts/build-many-glibcs.py (Context.add_all_configs): Add
soft-float ColdFire configuration.

Add localplt.data for ColdFire.
The sole failure for ColdFire in the compilation part of the glibc
testsuite is the localplt test. This patch adds a localplt baseline
for ColdFire to eliminate that failure. The difference from the
existing m68k baseline is that no PLT entry for _Unwind_Find_FDE is
expected, because ColdFire does not set
libc_cv_gcc_unwind_find_fde=yes.
Tested with build-many-glibcs.py.

Add no-FPU ColdFire math_private.h.
As with some other soft-float configurations, no-FPU ColdFire needs
various fenv.h functions and glibc-internal macros overridden in
math_private.h to avoid references to undefined FE_* macros when
building glibc. This patch adds a suitable math_private.h, based on
the MicroBlaze one (Nios II and Tile also have similar files).
There's a case for having such a file in sysdeps/ieee754/soft-fp so
this logic is applied more generally to configurations without
exceptions and rounding modes, even when the relevant macros are
defined in fenv.h - the only case where that might be inappropriate is
ARM soft-float (where the fenv.h functions might or might not work at
runtime, depending on whether the processor used at runtime supports
VFP). There's also a case that soft-float configurations (on
processors with both hard-float and soft-float) should more
consistently avoid defining FE_* macros in bits/fenv.h when not
actually supported. But both of those are separate potential
cleanups.
This allows the no-FPU ColdFire build to get further (another fix is
needed to allow the build to complete).
* sysdeps/m68k/coldfire/nofpu/math_private.h: New file. Based on
MicroBlaze file.

Add jmp_buf-macros.h for no-FPU ColdFire.
Continuing the fixes for ColdFire glibc build with

no-FPU build to progress further than without the patch (although
other fixes are still needed for the build to complete).

Add jmp_buf-macros.h for ColdFire.
This patch adds a jmp_buf-macros.h for ColdFire. In conjunction with
a GCC patch to fix the libgcc build failure for ColdFire
<https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02064.html> this
suffices to restore the build (tested with build-many-glibcs.py). A
further patch will be needed for soft-float ColdFire (while the
function-calling ABI is the same for hard-float and soft-float
ColdFire, it turns out the glibc ABI is not - so another ColdFire
variant will be needed in build-many-glibcs.py), but I'll deal with
that separately.
Tested with build-many-glibcs.py (m68k-linux-gnu and
m68k-linux-gnu-coldfire). (There's a localplt test failure for
coldfire; that's the only failure in the compilation part of the
testsuite.)

commit 95cb863a1ef7760a11272bbd7ba5fe62dc41be54
Author: Rafal Luzynski <address@hidden>

Implement alternative month names (bug 10871).
Some languages (Slavic, Baltic, etc.) require a genitive case of the
month name when formatting a full date (with the day number) while
they require a nominative case when referring to the month standalone.
This requirement cannot be fulfilled without providing two forms for
each month name. From now it is specified that nl_langinfo(MON_1)
series (up to MON_12) and strftime("%B") generate the month names in
the grammatical form used when the month is a part of a complete date.
If the grammatical form used when the month is named by itself is needed,
the new values nl_langinfo(ALTMON_1) (up to ALTMON_12) and
strftime("%OB") are supported. This new feature is optional so the
languages which do not need it or do not yet provide the updated
locales simply do not use it and their behaviour is unchanged.

powerpc: Fix syscalls during early process initialization [BZ #22685]
The tunables framework needs to execute syscall early in process
initialization, before the TCB is available for consumption. This
behavior conflicts with powerpc{|64|64le}'s lock elision code, that
checks the TCB before trying to abort transactions immediately before
executing a syscall.

Fix integer overflows in internal memalign and malloc functions [BZ #22343]
When posix_memalign is called with an alignment less than MALLOC_ALIGNMENT
and a requested size close to SIZE_MAX, it falls back to malloc code
(because the alignment of a block returned by malloc is sufficient to
satisfy the call). In this case, an integer overflow in _int_malloc leads
to posix_memalign incorrectly returning successfully.
Upon fixing this and writing a somewhat thorough regression test, it was
discovered that when posix_memalign is called with an alignment larger than
MALLOC_ALIGNMENT (so it uses _int_memalign instead) and a requested size
close to SIZE_MAX, a different integer overflow in _int_memalign leads to
posix_memalign incorrectly returning successfully.
Both integer overflows affect other memory allocation functions that use
_int_malloc (one affected malloc in x86) or _int_memalign as well.
This commit fixes both integer overflows. In addition to this, it adds a
regression test to guard against false successful allocations by the
following memory allocation functions when called with too-large allocation
sizes and, where relevant, various valid alignments:
malloc, realloc, calloc, reallocarray, memalign, posix_memalign,
aligned_alloc, valloc, and pvalloc.

Fix backtrace for hppa (bug 22719).
The only architecture in glibc that uses the generic debug/backtrace.c
is hppa. The debug/tst-backtrace* tests fail for hppa, so in fact the
generic debug/backtrace.c is not functional anywhere. Instead, the
x86_64 version is a reasonably generic version that uses
_Unwind_Backtrace from libgcc to backtrace using unwind info, and is
used by several architectures. This patch adds hppa to the
architectures using it (leaving open the possibility of a subsequent
cleanup for 2.28 of moving the x86_64 version to debug/backtrace.c,
and removing all the frame.h files that are now unused).
Reported by Adhemerval in
<https://sourceware.org/ml/libc-alpha/2018-01/msg00564.html> that this
does fix the backtrace test failures for hppa.

x86-64: Properly align La_x86_64_retval to VEC_SIZE [BZ #22715]
_dl_runtime_profile calls _dl_call_pltexit, passing a pointer to
La_x86_64_retval which is allocated on stack. The lrv_vector0
field in La_x86_64_retval must be aligned to size of vector register.
When allocating stack space for La_x86_64_retval, we need to make sure
that the address of La_x86_64_retval + RV_VECTOR0_OFFSET is aligned to
VEC_SIZE. This patch checks the alignment of the lrv_vector0 field
and pads the stack space if needed.

aarch64: fix static pie enabled libc when main is in a shared library
In the static pie enabled libc, crt1.o uses the same position independent
code as rcrt1.o and crt1.o is used instead of Scrt1.o when -no-pie
executables are linked. When main is not defined in the executable, but
in a shared library crt1.o is currently broken, it assumes main is local.
(glibc has a test for this but i missed it in my previous testing.)
To make both rcrt1.o and crt1.o happy with the same code, a wrapper is
introduced around main: with this crt1.o works with extern main symbol
while rcrt1.o does not depend on GOT relocations. (The change only
affects static pie enabled libc. Further simplification of start.S is
possible in the future by using the same approach for Scrt1.o too.)

linux: make getcwd(3) fail if it cannot obtain an absolute path [BZ #22679]
Currently getcwd(3) can succeed without returning an absolute path
because the underlying getcwd syscall, starting with linux commit
v2.6.36-rc1~96^2~2, may succeed without returning an absolute path.
This is a conformance issue because "The getcwd() function shall
place an absolute pathname of the current working directory
in the array pointed to by buf, and return buf".
This is also a security issue because a non-absolute path returned
by getcwd(3) causes a buffer underflow in realpath(3).
Fix this by checking the path returned by getcwd syscall and falling
back to generic_getcwd if the path is not absolute, effectively making
getcwd(3) fail with ENOENT. The error code is chosen for consistency
with the case when the current directory is unlinked.

The official orthography rules doesn't contain an explicit rule about

Make default libc_feholdsetround_noex_ctx use __feholdexcept (bug 22702).
For soft-float powerpc, the math/test-nearbyint-except-2 test fails
because nearbyintl traps when traps on "inexact" are enabled on entry
(and an "inexact" exception is generated internally, though cleared
for the final return).
The problem is the default implementation of
libc_feholdsetround_noex_ctx, which does not disable exception traps.
There is some ambiguity about whether the *noex* interfaces are
required to do so or only permitted to do so. But given that we
support fe* interfaces to enable and disable traps (on architectures
with that functionality), functions that must not raise an exception
(must not leave the flag set on exit if not set on entry) should also
not trap on it when traps on that exception are enabled. So it is
appropriate to define these interfaces to have the feholdexcept effect
of disabling exception traps; this patch updates the default
implementation and comments accordingly.
At least some architecture versions already disable traps; there are
few uses of the *noex* interfaces at all, and while it's possible
there are bugs on any architecture versions failing to disable traps

currently no tests, other than this one for nearbyintl (where only the

traps here, hence the nearbyintl failure not appearing there.)

clean math/ test results, provided you build with GCC 8 to get the fix

Fix ldbl-128ibm log1pl (-qNaN) spurious "invalid" exception (bug 22693).
The ldbl-128ibm implementation of log1pl does ordered comparisons on a
negative qNaN argument, so resulting in spurious "invalid" exceptions
(for soft-float powerpc; hard-float only avoids this because of GCC
bug 58684 meaning ordered comparison instructions never get
generated). This patch fixes this by arranging for the test for NaN
or infinity arguments to handle negative arguments as well.
Tested for powerpc (soft float).

The ldbl-128ibm implementations of lrintl and lroundl are missing
"invalid" exceptions for certain overflow cases when compiled with GCC
8. The cause of this is after-the-fact integer overflow checks that
fail when the compiler optimizes on the basis of integer overflow
being undefined; GCC 8 must be able to detect new cases of
undefinedness here.

(Tested that these failures occur before the patch for powerpc
soft-float, but the issue applies in principle for hard-float as well,
whether or not the particular optimizations in fact occur there at
present.)
This patch fixes the bug by ensuring the additions / subtractions in
question cast arguments to unsigned long int, or use 1UL as a constant
argument, so that the arithmetic occurs in an unsigned type with the
result then converted back to a signed type.

Fix powerpc-nofpu complex long double functions spurious "invalid"
exception (bug 22687).
For soft-float powerpc, various _Complex long double functions
generate spurious "invalid" exceptions, even with a compiler with GCC
bug 64811 fixed.
The problem is GCC's built-in fabsl expansion. Various files are
already built with -fno-builtin-fabsl because in this case (IBM long
double, for soft-float or e500v1) a fallback fabsl expansion based on
comparisons is used, which can produce the wrong sign of a zero
result. Those comparisons can also produce spurious exceptions for
NaN arguments. Furthermore, __builtin_fpclassify implemently uses
__builtin_fabsl, and is unaffected by -fno-builtin-fabsl, and the
fpclassify macro uses __builtin_fpclassify in the absence of
-fsignaling-nans. Thus, this patch arranges for the problem files
using fpclassify to be built with -fsignaling-nans in this case, to
avoid spurious exceptions from fpclassify.

(now that we have separate tests for it) and uses a tsearch tree

support: Increase usability of TEST_COMPARE
The previous implementation of the TEST_COMPARE macro would fail
to compile code like this:
int ret = res_send (query, sizeof (query), buf, sizeof (buf));
TEST_COMPARE (ret,
sizeof (query)
+ 2 /* Compression reference. */
+ 2 + 2 + 4 + 2 /* Type, class, TTL, RDATA length. */
+ 1 /* Pascal-style string length. */
+ strlen (expected_name));
This resulted in a failed static assertion, "integer conversions
may alter sign of operands". A user of the TEST_COMPARE would have
to add a cast to fix this.
This patch reverts to the original proposed solution of a run-time
check, making TEST_COMPARE usable for comparisons of numbers with
types with different signedness in more contexts.

[BZ #22637] Fix stack guard size accounting
Previously if user requested S stack and G guard when creating a
thread, the total mapping was S and the actual available stack was
S - G - static_tls, which is not what the user requested.
This patch fixes the guard size accounting by pretending the user
requested S+G stack. This way all later logic works out except
when reporting the user requested stack size (pthread_getattr_np)
or when computing the minimal stack size (__pthread_get_minstack).
Normally this will increase thread stack allocations by one page.
TLS accounting is not affected, that will require a separate fix.

Add test for getrlimit/setrlimit/prlimit with infinity value
Add a test to check that the getrlimit, setrlimit and prlimit functions
and their 64-bit equivalent behave correctly with RLIM_INFINITY and
RLIM64_INFINITY. For that it assumes that the prlimit64 function calls
the syscall directly without translating the value and that the kernel
uses the -1 value to represent infinity.
It first finds a resource with the hard limit set to infinity so the
soft limit can be manipulated easily and check for the consistency
between the value set or get by the prlimit64 and the other functions.
It is Linux specific add it uses the prlimit and prlimit64 functions.

* sysdeps/unix/sysv/linux/tst-rlimit-infinity.c: New file.

prlimit: Translate old_rlimit from RLIM64_INFINITY to RLIM_INFINITY [BZ
#22678]
prlimit called without a new value fails on 32-bit machines if any of
the soft or hard limits are infinity. This is because prlimit does not
translate old_rlimit from RLIM64_INFINITY to RLIM_INFINITY, but checks
that the value returned by the prlimit64 syscall fits into a 32-bit
value, like it is done for example in getrlimit. Note that on the
other hand new_rlimit is correctly translated from RLIM_INFINITY to
RLIM64_INFINITY before calling the syscall.
This patch fixes that.

Alpha: Add wrappers to get/setrlimit64 to fix RLIM64_INFINITY constant [BZ
#22648]
RLIM64_INFINITY was supposed to be a glibc convention rather than
anything seen by the kernel, but it ended being passed to the kernel
through the prlimit64 syscall.
* On the kernel side, the value is defined for the prlimit64 syscall for
all architectures in include/uapi/linux/resource.h:
#define RLIM64_INFINITY (~0ULL)
* On the kernel side, the value is defined for getrlimit and setrlimit
in arch/alpha/include/uapi/asm/resource.h
#define RLIM_INFINITY 0x7ffffffffffffffful
* On the GNU libc side, the value is defined in
sysdeps/unix/sysv/linux/alpha/bits/resource.h:
# define RLIM64_INFINITY 0x7fffffffffffffffLL
This was not an issue until the getrlimit and setrlimit glibc functions
have been changed in commit 045c13d185 ("Consolidate Linux setrlimit and
getrlimit implementation") to use the prlimit64 syscall instead of the
getrlimit and setrlimit ones.
This patch fixes that by adding a wrapper to fix the value passed to or
received from the kernel, before or after calling the prlimit64 syscall.

alpha: Remove s_trunc{f} implementation (BZ#22666)
As discussed in libc-alpha [1], alpha trunc{f} implementation uses
addt/suc and subt/suc and although the Alpha Architecture
Handbook version 3 states that that ADDx SUBx OUTPUT Exceptions
(B.3 Mapping to IEEE Standard) should not generate Inexact if INE
bit is set, the Alpha 21264 [2] chip manual (A.8 IEEE Floating-Point
Conformance) states that ADDx SUBx OUTPUT does generate inexact
exception for inexact result regardless.
As Joseph noted [3] to correctly fix it on alpha we need to either
avoid the instruction or avoid any inexact bit from it being set
on return from the function (while preserving the inexact bit that
might be set on the entry to the function). The later will result
mf_fpcr followed by a mt_fpcr to get and set the fpcr which will
defeat the optimization itself.
So the patch just remove the alpha optimized and rely on generic
implementation. It fixes the math/test-*-{trunc} on alpha.

Reduce command length in regen-ulps.
I found that "make regen-ulps" failed when building with unmodified
GNU make 4.1, and an objdir /some/where/math/ longer than about 37
characters, because the list of tests in the "for run in $^" loop
exceeded the Linux kernel's MAX_ARG_STRLEN limit (131072 bytes) on the
length of a single argument passed to a command.
Some GNU/Linux distributions have a patch to make to work around this
limit (see e.g. Debian bug 688601), but clearly this ought to work
without needing such a patch. This patch arranges for the shell loop
to be over the test names without a $(objdir) prefix, which reduces
the space used to less than half MAX_ARG_STRLEN.
(I think we ought to aim to get rid of bits/mathinline.h completely -
filing GCC bugs for any optimizations GCC can't currently do with
-ffast-math - which would mean we could halve the number of libm tests
run because separate inline function tests would no longer be needed.
However, with a long directory name even half the number of tests
could make this command exceed MAX_ARG_STRLEN without my patch.)
Tested regen-ulps on a system where it failed before this patch.
* math/Makefile (run-regen-ulps): Add $(objpfx) to test name here.
(regen-ulps): Use $(libm-tests) not $^ in shell loop.

Remove alpha specific fmax, fmin to fix sNaN handling [BZ #22660]
Various fmax and fmin function implementations mishandle sNaN
arguments:
(a) When both arguments are NaNs, the return value should be a qNaN,
but sometimes it is an sNaN if at least one argument is an sNaN.
(b) Under TS 18661-1 semantics, if either argument is an sNaN then the
result should be a qNaN (whereas if one argument is a qNaN and the
other is not a NaN, the result should be the non-NaN argument).
Various implementations treat sNaNs like qNaNs here.
One way to fix that is to detect the sNaN and add a special case. That
said there is no FPU instruction to do that, so it requires transfering
the FP value to an integer register and testing bits. This becomes quite
complicated so it's probably better to just use the generic versions of
these functions which just do that through issignaling.

elf: Check for empty tokens before dynamic string token expansion [BZ
#22625]
The fillin_rpath function in elf/dl-load.c loops over each RPATH or
RUNPATH tokens and interprets empty tokens as the current directory
("./"). In practice the check for empty token is done *after* the
dynamic string token expansion. The expansion process can return an
empty string for the $ORIGIN token if __libc_enable_secure is set
or if the path of the binary can not be determined (/proc not mounted).
Fix that by moving the check for empty tokens before the dynamic string
token expansion. In addition, check for NULL pointer or empty strings
return by expand_dynamic_string_token.
The above changes highlighted a bug in decompose_rpath, an empty array
is represented by the first element being NULL at the fillin_rpath
level, but by using a -1 pointer in decompose_rpath and other functions.
Changelog:

scandir: fix wrong assumption about errno [BZ #17804]
malloc and realloc may set errno to ENOMEM even if they are successful.
The scandir code wrongly assume that they do not change errno, this
causes scandir to fail with ENOMEM even if malloc succeed.
The code already handles that readdir might set errno by calling
__set_errno (0) to clear the error. Move that part at the end of the
loop to also take malloc and realloc into account.
Changelog:
[BZ #17804]
* dirent/scandir-tail.c (SCANDIR_TAIL): Move __set_errno (0) at the
end of the loop. Improve comments.

manual: clarify errno value on success [BZ #22615]
The current glibc manual is ambiguous about the errno value on success
and suggests that it is left unchanged. Some functions might and
sometimes do change the errno value, however they never set it to 0.
This patch from Zack Weinberg clarifies this section of the manual.
Changelog:

might be set on success.

elf: remove redundant code from is_dst
is_dst is called either by _dl_dst_count or by _dl_dst_substitute.
_dl_dst_count is called by DL_DST_COUNT only.
DL_DST_COUNT is called either by expand_dst with is_path == 0
or by expand_dynamic_string_token.
_dl_dst_substitute is called either from expand_dst with is_path == 0
or from expand_dynamic_string_token.
The latter function is called either from _dl_map_object with is_path == 0
or from fillin_rpath with is_path == 1 and name containing no ':'.
In any case (is_path && name[i] == ':') is always false and all code
depending on it can be safely removed.
* elf/dl-load.c (is_dst): Remove checks that is_path is set and name
contains ':', and all code depending on these checks.

There are just two users of _dl_dst_substitute: one is expand_dst that

sets is_path argument to 0, another one is fillin_rpath that sets
is_path argument to 1 and name argument contains no ':'.
In any case (is_path && name[i] == ':') is always false and all code
depending on it can be safely removed.

Deprecate external use of libio.h and _G_config.h.
libio.h was originally the header for a set of supported GNU
extensions, but they have not been maintained as such in many years,
they are now standing in the way of improvements to stdio, and we
don't think there are any remaining external users. _G_config.h was
never intended for public use, but predates the bits convention.
Move both of these headers into the bits directory and provide stubs
at top level which issue deprecation warnings.
The contents of (bits/)libio.h and (bits/)_G_config.h are still
exposed to external software via stdio.h; changing that requires more
complex surgery than I have time to attempt right now.

deprecation warning and then include <bits/libio.h>, <bits/_G_config.h>

nptl: Consolidate pthread_{timed,try}join{_np}
This patch consolidates the pthread_join and gnu extensions to avoid
code duplication. The function pthread_join, pthread_tryjoin_np, and
pthread_timedjoin_np are now based on pthread_timedjoin_ex.
It also fixes some inconsistencies on ESRCH, EINVAL, EDEADLK handling
(where each implementation differs from each other) and also on
clenup handler (which now always use a CAS).

nptl: Implement pthread_self in libc.so [BZ #22635]
All binaries use TLS and thus need a properly set up TCB, so we can
simply return its address directly, instead of forwarding to the
libpthread implementation from libc.
For versioned symbols, the dynamic linker checks that the soname matches
the name supplied by the link editor, so a compatibility symbol in
libpthread is needed.
To avoid linking against the libpthread function in all cases, we would
have to bump the symbol version of libpthread in libc.so and supply a
compat symbol. This commit does not do that because the function
implementation is so small, so the overhead by two active copies of the
same function might well be smaller than the increase in symbol table
size.

Provide a C++ version of iseqsig (bug 22377)
In C++ mode, __MATH_TG cannot be used for defining iseqsig, because
__MATH_TG relies on __builtin_types_compatible_p, which is a C-only
builtin. This is true when float128 is provided as an ABI-distinct type
from long double.
Moreover, the comparison macros from ISO C take two floating-point
arguments, which need not have the same type. Choosing what underlying
function to call requires evaluating the formats of the arguments, then
selecting which is wider. The macro __MATH_EVAL_FMT2 provides this
information, however, only the type of the macro expansion is relevant
(actually evaluating the expression would be incorrect).
This patch provides a C++ version of iseqsig, in which only the type of
__MATH_EVAL_FMT2 (__typeof or decltype) is used as a template parameter
for __iseqsig_type. This function calls the appropriate underlying
function.
Tested for powerpc64le and x86_64.

elf: remove redundant __libc_enable_secure check from fillin_rpath
There are just two users of fillin_rpath: one is decompose_rpath that
sets check_trusted argument to 0, another one is _dl_init_paths that
sets check_trusted argument to __libc_enable_secure and invokes
fillin_rpath only when LD_LIBRARY_PATH is non-empty.
Starting with commit
glibc-2.25.90-512-gf6110a8fee2ca36f8e2d2abecf3cba9fa7b8ea7d,
LD_LIBRARY_PATH is ignored for __libc_enable_secure executables,
so check_trusted argument of fillin_rpath is always zero.
* elf/dl-load.c (is_trusted_path): Remove.
(fillin_rpath): Remove check_trusted argument and its use,
all callers changed.

Pass -no-pie to GCC only if GCC defaults to PIE [BZ #22614]
$(no-pie-ldflag) is no longer effective since no-pie-ldflag is defined
to -no-pie only if GCC defaults to PIE. When --enable-static-pie is
used to configure glibc build and GCC doesn't default to PIE. no-pie-ldflag
is undefined and these tests:
elf/Makefile:LDFLAGS-tst-dlopen-aout = $(no-pie-ldflag)
elf/Makefile:LDFLAGS-tst-prelink = $(no-pie-ldflag)
elf/Makefile:LDFLAGS-tst-main1 = $(no-pie-ldflag)
gmon/Makefile:LDFLAGS-tst-gmon := $(no-pie-ldflag)
may fail to link. This patch replaces "-pie" with
$(if $($(@F)-no-pie),$(no-pie-ldflag),-pie)
and repleces
LDFLAGS-* = $(no-pie-ldflag)
with
tst-*-no-pie = yes
so that tst-dlopen-aout, tst-prelink, tst-main1 and tst-gmon are always
built as non-PIE, with and without --enable-static-pie, regardless if
GCC defaults to PIE or non-PIE.
Tested with build-many-glibcs.py without --enable-static-pie as well as
with --enable-static-pie for x86_64, x32 and i686.

Document that --enable-static-pie implies PIE
To build static PIE, all .o files are compiled with -fPIE. Since
--enable-static-pie is designed to provide additional security hardening
benefits, it also implies that glibc programs and tests are created as
dynamic position independent executables (PIE) by default for better
security hardening.

Avoid signed shift overflow in pow (bug 21309).
As noted in bug 21309, dbl-64/e_pow.c contains signed int shifts that,
although the shift count is in the range [0, 31], shift bits into and
beyond the sign bit and so are undefined in ISO C. Although this is

those shifts.

Improve __ieee754_exp() performance by greater than 5x on sparc/x86.
These changes will be active for all platforms that don't provide
their own exp() routines. They will also be active for ieee754
versions of ccos, ccosh, cosh, csin, csinh, sinh, exp10, gamma, and
erf.
Typical performance gains is typically around 5x when measured on
Sparc s7 for common values between exp(1) and exp(40).
Using the glibc perf tests on sparc,
sparc (nsec) x86 (nsec)
old new old new
max 17629 395 5173 144
min 399 54 15 13
mean 5317 200 1349 23
The extreme max times for the old (ieee754) exp are due to the
multiprecision computation in the old algorithm when the true value is
very near 0.5 ulp away from an value representable in double
precision. The new algorithm does not take special measures for those
cases. The current glibc exp perf tests overrepresent those values.
Informal testing suggests approximately one in 200 cases might
invoke the high cost computation. The performance advantage of the new
algorithm for other values is still large but not as large as indicated
by the chart above.
Glibc correctness tests for exp() and expf() were run. Within the
test suite 3 input values were found to cause 1 bit differences (ulp)
when "FE_TONEAREST" rounding mode is set. No differences in exp() were
seen for the tested values for the other rounding modes.
Typical example:
exp(-0x1.760cd2p+0) (-1.46113312244415283203125)
new code: 2.31973271630014299393707e-01 0x1.db14cd799387ap-3
old code: 2.31973271630014271638132e-01 0x1.db14cd7993879p-3
exp = 2.31973271630014285508337 (high precision)
Old delta: off by 0.49 ulp
New delta: off by 0.51 ulp
In addition, because ieee754_exp() is used by other routines, cexp()
showed test results with very small imaginary input values where the
imaginary portion of the result was off by 3 ulp when in upward
rounding mode, but not in the other rounding modes. For x86, tgamma
showed a few values where the ulp increased to 6 (max ulp for tgamma
is 5). Sparc tgamma did not show these failures. I presume the tgamma
differences are due to compiler optimization differences within the
gamma function.The gamma function is known to be difficult to compute
accurately.

ia64: Fix memchr for large input sizes (BZ #22603)
Current optimized ia64 memchr uses a strategy to check for last address
by adding the input one with expected size. However it does not take
care for possible overflow.
It was triggered by 3038145ca23 where default rawmemchr now uses memchr
(p, c, (size_t)-1).
This patch fixes it by implement a satured addition where overflows
sets the maximum pointer size to UINTPTR_MAX.

Linux/x86: Update cancel_jmp_buf to match __jmp_buf_tag [BZ #22563]
On x86, padding in struct __jmp_buf_tag is used for shadow stack pointer
to support shadow stack in Intel Control-flow Enforcemen Technology.
Since the cancel_jmp_buf array is passed to setjmp and longjmp by
casting it to pointer to struct __jmp_buf_tag, it should be as large
as struct __jmp_buf_tag. Otherwise when shadow stack is enabled,
setjmp and longjmp will write and read beyond cancel_jmp_buf when saving
and restoring shadow stack pointer.
This patch adds bits/types/__cancel_jmp_buf_tag.h to define struct
__cancel_jmp_buf_tag so that Linux/x86 can add saved_mask to
cancel_jmp_buf.

Fix m68k bits/mathinline.h attributes (bug 22631).
m68k bits/mathinline.h declares various functions with const
attributes. These are inappropriate for functions that have results
depending on the rounding mode; the machine-independent
bits/mathcalls.h only uses const attributes for a very few functions
with no rounding mode dependence, and the m68k header should do
likewise. GCC uses pure for such functions with -frounding-math,
resulting in GCC mainline warning for conflicts with between the
header and the built-in attributes and glibc failing to build for m68k
with GCC mainline.
This patch fixes the attributes to avoid using const except when
bits/mathcalls.h does so. (There are a few functions where maybe
bits/mathcalls.h could do so but doesn't, but keeping the headers in
sync in this regard seems to be the safe approach.)

Fix build-many-glibcs.py arm-linux-gnueabihf builds with mainline GCC.
My fix to make the arm-linux-gnueabihf build-many-glibcs.py builds
actually use the hard-float ABI as intended showed up another issue
when building with mainline GCC: GCC now determines an FPU based on
the selected CPU or architecture and gives an error for
-mfloat-abi=hard when the CPU does not imply a choice of FPU. This
patch fixes all the affected configurations to specify a suitable
--with-cpu, --with-fpu or -mfpu option explicitly to avoid that error
from GCC.

Disable -Wrestrict for two nptl/tst-attr3.c tests.
nptl/tst-attr3 fails to build with GCC mainline because of
(deliberate) aliasing between the second (attributes) and fourth
(argument to thread start routine) arguments to pthread_create.
Although both those arguments are restrict-qualified in POSIX,
pthread_create does not actually dereference its fourth argument; it's
an opaque pointer passed to the thread start routine. Thus, the
aliasing is actually valid in this case, and it's deliberate in the
test. So this patch makes the test disable -Wrestrict for the two
pthread_create calls in question. (-Wrestrict was added in GCC 7,
hence the __GNUC_PREREQ conditions, but the particular warning in
question is new in GCC 8.)

This patch fixes the test to avoid such truncation warnings by
increasing the buffer in question by one byte, to ensure it can hold
any possible result of %s? or %s* formats where %s comes from a buffer
of size PATH_MAX.
Tested compilation with build-many-glibcs.py for aarch64-linux-gnu.

Disable strncat test array-bounds warnings for GCC 8.
Some strncat tests fail to build with GCC 8 because of -Warray-bounds
warnings. These tests are deliberately test over-large size arguments
passed to strncat, and already disable -Wstringop-overflow warnings,
but now the warnings for these tests come under -Warray-bounds so that
option needs disabling for them as well, which this patch does (with
an update on the comments; the DIAG_IGNORE_NEEDS_COMMENT call for
-Warray-bounds doesn't need to be conditional itself, because that
option is supported by all versions of GCC that can build glibc).
Tested compilation with build-many-glibcs.py for aarch64-linux-gnu.
* string/tester.c (test_strncat): Also disable -Warray-bounds
warnings for two tests.

Pass -no-pie to GCC only if GCC defaults to PIE [BZ #22614]
After --enable-static-pie is added to configure, libc_cv_pie_default is
set to yes when either --enable-static-pie is used to configure glibc
or GCC defaults to PIE. We should set no-pie-ldflag to -no-pie, which
is supported on GCC 6 and later, only if GCC defaults to PIE, not when
--enable-static-pie is used to configure glibc.
Tested on x32 with --enable-static-pie using GCC 5 and without

ld.so: Examine GLRO to detect inactive loader [BZ #20204]
GLRO (_rtld_global_ro) is read-only after initialization and can
therefore not be patched at run time, unlike the hook table addresses
and their contents, so this is a desirable hardening feature.
The hooks are only needed if ld.so has not been initialized, and this
happens only after static dlopen (dlmopen uses a single ld.so object
across all namespaces).

Fix nscd readlink argument aliasing (bug 22446).
Current GCC mainline detects that nscd calls readlink with the same
buffer for both input and output, which is not valid (those arguments
are both restrict-qualified in POSIX). This patch makes it use a
separate buffer for readlink's input (with a size that is sufficient
to avoid truncation, so there should be no problems with warnings
about possible truncation, though not strictly minimal, but much
smaller than the buffer for output) to avoid this problem.
Tested compilation for aarch64-linux-gnu with build-many-glibcs.py.

mips64: fix clobbering s0 in setjmp() [BZ #22624]
When configured as --enable-stack-protector=all glibc
inserts stack checking canary into every function
including __sigsetjmp_aux(). Stack checking code
ends up using s0 register to temporary hold address
of global canary value.
Unfortunately __sigsetjmp_aux assumes no caller' caller-save
registers should be clobbered as it stores them as-is.
The fix is to disable stack protection of __sigsetjmp_aux.
Tested on the following test:
#include <setjmp.h>
#include <stdio.h>
int main() {
jmp_buf jb;
volatile register long s0 asm ("$s0");
s0 = 1234;
if (setjmp(jb) == 0)
longjmp(jb, 1);
printf ("$s0 = %lu\n", s0);
}
Without the fix:
$ qemu-mipsn32 -L . ./mips-longjmp-bug
$s0 = 1082346228
With the fix:

elf: do not substitute dst in $LD_LIBRARY_PATH twice [BZ #22627]
Starting with commit
glibc-2.18.90-470-g2a939a7e6d81f109d49306bc2e10b4ac9ceed8f9 that
introduced substitution of dynamic string tokens in fillin_rpath,
_dl_init_paths invokes _dl_dst_substitute for $LD_LIBRARY_PATH twice:
the first time it's called directly, the second time the result
is passed on to fillin_rpath which calls expand_dynamic_string_token
which in turn calls _dl_dst_substitute, leading to the following
behaviour:
$ mkdir -p /tmp/'$ORIGIN' && cd /tmp/'$ORIGIN' &&
echo 'int main(){}' |gcc -xc - &&
strace -qq -E LD_LIBRARY_PATH='$ORIGIN' -e /open ./a.out
open("/tmp//tmp/$ORIGIN/tls/x86_64/libc.so.6", O_RDONLY|O_CLOEXEC) = -1
ENOENT (No such file or directory)
open("/tmp//tmp/$ORIGIN/tls/libc.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No

aarch64: fix start code for static pie
There are three flavors of the crt startup code:
1) crt1.o used for non-pie,
2) Scrt1.o used for dynamic linked pie (dynamic linker relocates),
3) rcrt1.o used for static linked pie (self relocation is needed)
In the --enable-static-pie case crt1.o is built with -DPIC and in case
of static linking it interposes _dl_relocate_static_pie in libc to
avoid self relocation.
Scrt1.o is built with -DPIC -DSHARED and it relies on GOT entries that
the static linker cannot relax and thus need relocation before the
start code is executed, so rcrt1.o needs separate implementation.
This implementation does not work for .text > 4G position independent
executables, which is fine since the toolchain does not support
-mcmodel=large with -fPIE.
Tests pass with ld/22269 and ld/22263 binutils bugs fixed.

ldconfig: set LC_COLLATE to C [BZ #22505]
ldconfig supports `include' directives and use the glob function to
process them. The glob function sort entries according to the LC_COLLATE
category. When using a standard "include /etc/ld.so.conf.d/*.conf" entry
in /etc/ld.so.conf, the order therefore depends on the locale used to
run ldconfig. A few examples of locale specific order that might be
disturbing in that context compared to the C locale:
- The cs_CZ and sk_SK locales sort the digits after the letters.
- The et_EE locale sorts the 'z' between 's' and 't'.
This patch fixes that by setting LC_COLLATE to C in order to process
files in deterministic order, independently of the locale used to launch
ldconfig.
NOTE: This should NOT be backported to older release branches.
Changelog:
[BZ #22505]
* elf/ldconfig.c (main): Call setlocale to force LC_COLLATE to C.

Fix tst-leaks1 (bug 14681)
The test tst-leaks1 exercises calling dlopen with a $ORIGIN DST.
This results in a theoretical leak e.g.
Memory not freed:

==27582== by 0x4E39F70: dlopen@@GLIBC_2.2.5 (dlopen.c:87)
There is no real leak.
The calling link map (the executable's link map) has it's l_origin
expanded for future use as part of _dl_get_origin, and that results
in the main executable link map having a N-byte allocation for
l->l_origin that is never freed since the executable's link map is
just a part of the process.
To take this into account we do one dlopen with $ORIGIN before
calling mtrace to force the initialization of the executable link
map.

Add --enable-static-pie configure option to build static PIE [BZ #19574]
Static PIE extends address space layout randomization to static
executables. It provides additional security hardening benefits at
the cost of some memory and performance.
Dynamic linker, ld.so, is a standalone program which can be loaded at
any address. This patch adds a configure option, --enable-static-pie,
to embed the part of ld.so in static executable to create static position
independent executable (static PIE). A static PIE is similar to static
executable, but can be loaded at any address without help from a dynamic
linker. When --enable-static-pie is used to configure glibc, libc.a is
built as PIE and all static executables, including tests, are built as
static PIE. The resulting libc.a can be used together with GCC 8 or
above to build static PIE with the compiler option, -static-pie. But
GCC 8 isn't required to build glibc with --enable-static-pie. Only GCC
with PIE support is needed. When an older GCC is used to build glibc
with --enable-static-pie, proper input files are passed to linker to
create static executables as static PIE, together with "-z text" to
prevent dynamic relocations in read-only segments, which are not allowed
in static PIE.
The following changes are made for static PIE:
1. Add a new function, _dl_relocate_static_pie, to:
a. Get the run-time load address.
b. Read the dynamic section.
c. Perform dynamic relocations.
Dynamic linker also performs these steps. But static PIE doesn't load
any shared objects.
2. Call _dl_relocate_static_pie at entrance of LIBC_START_MAIN in
libc.a. crt1.o, which is used to create dynamic and non-PIE static
executables, is updated to include a dummy _dl_relocate_static_pie.
rcrt1.o is added to create static PIE, which will link in the real
_dl_relocate_static_pie. grcrt1.o is also added to create static PIE
with -pg. GCC 8 has been updated to support rcrt1.o and grcrt1.o for
static PIE.
Static PIE can work on all architectures which support PIE, provided:
1. Target must support accessing of local functions without dynamic
relocations, which is needed in start.S to call __libc_start_main with
function addresses of __libc_csu_init, __libc_csu_fini and main. All
functions in static PIE are local functions. If PIE start.S can't reach
main () defined in a shared object, the code sequence:
pass address of local_main to __libc_start_main
...
local_main:
tail call to main via PLT
can be used.
2. start.S is updated to check PIC instead SHARED for PIC code path and
avoid dynamic relocation, when PIC is defined and SHARED isn't defined,
to support static PIE.
3. All assembly codes are updated check PIC instead SHARED for PIC code
path to avoid dynamic relocations in read-only sections.
4. All assembly codes are updated check SHARED instead PIC for static
symbol name.
5. elf_machine_load_address in dl-machine.h are updated to support static
PIE.
6. __brk works without TLS nor dynamic relocations in read-only section
so that it can be used by __libc_setup_tls to initializes TLS in static
PIE.
NB: When glibc is built with GCC defaulted to PIE, libc.a is compiled
with -fPIE, regardless if --enable-static-pie is used to configure glibc.
When glibc is configured with --enable-static-pie, libc.a is compiled
with -fPIE, regardless whether GCC defaults to PIE or not. The same
libc.a can be used to build both static executable and static PIE.
There is no need for separate PIE copy of libc.a.
On x86-64, the normal static sln:
text data bss dec hex filename
625425 8284 5456 639165 9c0bd elf/sln
the static PIE sln:
text data bss dec hex filename
657626 20636 5392 683654 a6e86 elf/sln
The code size is increased by 5% and the binary size is increased by 7%.
Linker requirements to build glibc with --enable-static-pie:
1. Linker supports --no-dynamic-linker to remove PT_INTERP segment from
static PIE.
2. Linker can create working static PIE. The x86-64 linker needs the
fix for
https://sourceware.org/bugzilla/show_bug.cgi?id=21782
The i386 linker needs to be able to convert "movl address@hidden(%ebx),
%eax"
to "leal address@hidden(%ebx), %eax" if main is defined locally.
Binutils 2.29 or above are OK for i686 and x86-64. But linker status for
other targets need to be verified.
3. Linker should resolve undefined weak symbols to 0 in static PIE:
https://sourceware.org/bugzilla/show_bug.cgi?id=22269
4. Many ELF backend linkers incorrectly check bfd_link_pic for TLS
relocations, which should check bfd_link_executable instead:
https://sourceware.org/bugzilla/show_bug.cgi?id=22263
Tested on aarch64, i686 and x86-64.

Fix testing with read-only source directory.
Three tests fail with a read-only source directory because they try to
write into the source directory. None of these write into it in a way
that should actually be problematic for concurrent builds sharing the
same writable source directory, but avoiding any writing into the
source directory (from testing, or from building glibc if the source
timestamps are properly ordered) is still a good idea, as being able
to build with read-only sources helps make sure there isn't anything
that could cause problems for concurrent builds.
This patch changes the tests in question to use either /tmp or the
build directory to write their temporary files (or to test O_TMPFILE,
as applicable).

Do not build .mo files in source directory (bug 14121).
Building and installing glibc leaves .mo files (compiled message
translations) behind in the source directory. Building those files in
the source directory may once have made sense, if they were included
in release tarballs; now that release tarballs are just the output of
"git archive", building any non-checked-in files in the source
directory does not make sense. This patch changes these files to be
built in the build directory instead. The realclean rule is changed
to simply adding the .mo files to the "generated" variable, since once
the files are in the build directory it make no sense to exclude them
from normal cleanup rules.
This is necessary but not sufficient to avoid build-many-glibcs.py
needing to copy the glibc source directory. Its list of files to
touch on checkout to avoid subsequent regeneration (configure,
preconfigure, *-kw.h) is incomplete (missing at least INSTALL,
sysdeps/gnu/errlist.c, posix/testcases.h, posix/ptestcases.h,
locale/C-translit.h, (only regenerated for Hurd builds)
sysdeps/mach/hurd/bits/errno.h, (only regenerated for 32-bit SPARC
builds) sysdeps/sparc/sparc32/{sdiv,udiv,rem,urem}.S) - the existing
list may be sufficient to prevent regeneration that actually changes
the file contents depending on the installed build tools, but not to
ensure there is no regeneration at all - and there might well be other
things writing into the source directory in the course of building and
testing (so needing appropriate testing with read-only source
directories with different timestamp orderings to find and eliminate
all such cases).
Tested for x86_64.

Update SPARC divrem generation to match output.
While working on another patch I noticed that (a)
sysdeps/sparc/sparc32/Makefile is the only place with special
realclean settings, apart from po/, and (b) the generated files with a
rule in that Makefile to generate them (using m4) had been patched
manually so no longer corresponded with the output of the generator -
so if the timestamps were wrong, a build would result in changes to
the files in the source directory. (They also didn't correspond
because of changes in make 3.81 to how make handles whitespace at the
start of a line in a sequence of backslash-newline continuation lines
within a recipe.)
This patch fixes the generation and output files to match. The issue
with make and whitespace at start of continuation lines is fixed by
putting those newlines outside of arguments to echo, so the number of
spaces in the argument matches the number in the existing generated
files. Then divrem.m4 is changed to avoid generating whitespace-only
lines (my fix to the outputs from 2013; this fix to the generator also
changes the indentation of a label in the output files) and to
generate an alias in udiv.S (Adhemerval's fix from March).
build-many-glibcs.py doesn't have a non-v9 SPARC configuration,
because non-v9 32-bit SPARC didn't build when I set up
build-many-glibcs.py but sparcv9 did build. Whether or not non-v9
32-bit SPARC now builds (or indeed whether or not support for it is
obsolete), I tested by removing the sparcv8 and sparcv9 versions of
the four files in question, so forcing the generated files to be built
and used, and the compilation parts of the glibc testsuite passed.

Add sysdeps/ieee754/soft-fp.
The default sysdeps/ieee754 fma implementations rely on exceptions and
rounding modes to achieve correct results through internal use of
round-to-odd. Thus, glibc configurations without support for
exceptions and rounding modes instead need to use implementations of
fma based on soft-fp.
At present, this is achieved via having implementation files in
soft-fp/ that are #included by sysdeps files for each glibc
configuration that needs them. In general this means such a
configuration has its own s_fma.c and s_fmaf.c.
TS 18661-1 adds functions that do an operation (+ - * / sqrt fma) on
arguments wider than the return type, with a single rounding of the
infinite-precision result to that return type. These are also
naturally implemented using round-to-odd on platforms with hardware
support for rounding modes and exceptions but lacking hardware support
for these narrowing operations themselves. (Platforms that have
direct hardware support for such narrowing operations include at least
ia64, and Power ISA 2.07 or later, which I think means POWER8 or
later.)
So adding the remaining TS 18661-1 functions would mean at least six
narrowing function implementations (fadd fsub fmul fdiv ffma fsqrt),
with aliases for other types and further implementations in some
configurations, that need to be overridden for configurations lacking
hardware exceptions and rounding modes. Requiring all such
configurations (currently seven of them) to have their own source
files for all those functions seems undesirable.
Thus, this patch adds a directory sysdeps/ieee754/soft-fp to contain
libm function implementations based on soft-fp. This directory is
then used via Implies from all the configurations that need it, so no
more files need adding to every such configuration when adding more
functions with soft-fp implementations. A configuration can still
selectively #include a particular file from this directory if desired;
thus, the MIPS #include of the fmal implementation is retained, since
that's appropriate even for hard float (because long double is always
implementated in software for MIPS64, so the soft-fp implementation of
fmal is better than the ldbl-128 one).
This also provides additional motivation for my recent patch removing
--with-fp / --without-fp: previously there was no need for correct use
of --without-fp for no-FPU ARM or SH3, and now we have autodetection
nofpu/ sysdeps directories can be used by this patch for those
configurations without imposing any new requirements on how glibc is
configured.
(The mips64/*/fpu/s_fma.c files added by this patch are needed to keep
the dbl-64 version of fma for double, rather than the ldbl-128 one,
used in that case.)
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by this patch.

libio: Free backup area when it not required (BZ#22415)
Some libio operations fail to correctly free the backup area (created
by _IO_{w}default_pbackfail on unget{w}c) resulting in either invalid
buffer free operations or memory leaks.
For instance, on the example provided by BZ#22415 a following
fputc after a fseek to rewind the stream issues an invalid free on
the buffer. It is because although _IO_file_overflow correctly
(from fputc) correctly calls _IO_free_backup_area, the
_IO_new_file_seekoff (called by fseek) updates the FILE internal
pointers without first free the backup area (resulting in invalid
values in the internal pointers).
The wide version also shows an issue, but instead of accessing invalid
pointers it leaks the backup memory on fseek/fputwc operation.
Checked on x86_64-linux-gnu and i686-linux-gnu.
* libio/Makefile (tests): Add tst-bz22415.
(tst-bz22415-ENV): New rule.

When running strace, IPC_64 was set in the command, but ia64 is

in the kernel, so ipc_parse_version just returns IPC_64 without
clearing the IPC_64 bit in the command.

Remove --with-fp / --without-fp.
There is a configure option --without-fp that specifies that nofpu
sysdeps directories should be used instead of fpu directories.
For most glibc configurations, this option is of no use: either there
is no valid nofpu variant of that configuration, or there are no fpu
or nofpu sysdeps directories for that processor and so the option does
nothing. For a few configurations, if you are using a soft-float
compiler this option is required, and failing to use it generally
results in compilation errors from inline asm using unavailable
floating-point instructions.
We're moving away from --with-cpu to configuring glibc based on how
the compiler generates code, and it is natural to do so for
--without-fp as well; in most cases the soft-float and hard-float ABIs
are incompatible so you have no hope of building a working glibc with
an inappropriately configured compiler or libgcc.
This patch eliminates --without-fp, replacing it entirely by automatic
configuration based on the compiler. Configurations for which this is
relevant (coldfire / mips / powerpc32 / sh) define a variable
with_fp_cond in their preconfigure fragments (under the same
conditions under which those fragments do anything); this is a
preprocessor conditional which the toplevel configure script then uses
in a test to determine which sysdeps directories to use.
The config.make with-fp variable remains. It's used only by powerpc
(sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various
flags variables. For powerpc, -mcpu= options can imply use of
soft-float. That could be an issue if you want to build for
e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp
sysdeps directory. If in future we eliminate --with-cpu and replace
it entirely by testing the compiler, it would be natural at that point
to eliminate that code as well (as the user should then just use a
compiler defaulting to 476fp and the 476 sysdeps directory would be
used automatically).
Tested for x86_64, and tested with build-many-glibcs.py that installed
shared libraries are unchanged by this patch.

S390: Add CFI rule in _dl_runtime_resolve[_vx] for unwinding.
In _dl_runtime_resolve[_vx], unwinding fails after the new stack frame
is created as there is no CFI rule for r15. This is also observeable in
GDB: Backtrace stopped: previous frame inner to this frame (corrupt stack?)
Therefore this patch is now storing r15 on stack and is using cfi_offset
rule.
The stmg/lmg instruction is used to store/load r14 and r15 with one
instruction.
On 64bit, the offsets of the fprs have moved to store r15 directly after
r14.
On 31bit, the r14/r15 is now stored between the other gprs and fprs as the
space
wasn't used.
ChangeLog:
* sysdeps/s390/s390-64/dl-trampoline.h (_dl_runtime_resolve):
Store r15 on stack and add cfi rule.
* sysdeps/s390/s390-32/dl-trampoline.h (_dl_runtime_resolve):

Fix ctanh (0 + i NaN), ctanh (0 + i Inf) (bug 22568, DR#471).
As per C11 DR#471, ctanh (0 + i NaN) and ctanh (0 + i Inf) should
return 0 + i NaN (with "invalid" exception in the second case but not
the first), not NaN + i NaN. This has corresponding implications for
ctan since its special cases are defined by ctan (z) = -i ctanh (iz).
This patch implements these cases for ctanh and ctan, updating
tests accordingly.
Tested for x86_64.

Add _Float32 function aliases.
This patch concludes filling out TS 18661-3 support for different
types by adding *f32 function aliases of float functions to support
_Float32. As with _Float64 and _Float32x, this is supported for all
glibc configurations. As with the previous such patches there are
some x86 ulps updates because of inline functions present for float
but not for _Float32. The patch also has the usual
bits/floatn-common.h update, symbol versions, ABI baselines updates,
test enablement and documentation.

GCC 6 and GCC 7.

Make cacosh (0 + iNaN) return NaN + i pi/2 (bug 22561, DR#471).
As per C11 DR#471 (adjusted resolution accepted for C17), cacosh (0 +
iNaN) should return NaN +/- i pi/2, not NaN + iNaN.
This patch fixes the code accordingly. The test has hardcoded the
result with positive sign of the imaginary part (with an associated
comment), since the unspecified sign for a result other than 0 or
infinity isn't currently supported by the test infrastructure.
Tested for x86_64.

Don't make local variables static in ldbl-96 j1l.
The ldbl-96 implementation of j1l has some function-local variables
that are declared static for no apparent reason (this dates back to
the first addition of that file).
Any vaguely recent compiler, probably including any that are supported
for building glibc, optimizes away the "static" here, as the values of
the variables on entry to the function are dead. So there is not
actually a user-visible bug here at present (but with any compilers
that didn't optimize away the static at all, possibly building with
less or no optimization, so that the function stored intermediate
values to and then loaded them from the variables, there would have
been a thread-safety issue). But the "static" clearly doesn't belong
there and might potentially make things unsafe were compilation
without optimization to be supported in future, so this patch removes
it.
Tested for x86_64.

Make some ldbl-128, ldbl-128ibm arrays const.
I noticed that an x86_64 build of libm unexpectedly contained more
non-constant data than an older version (before _Float128 support)

ldbl-128ibm ones, const.

Add _Float64, _Float32x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64 and
*f32x function aliases, supporting _Float64 and _Float32x, as aliases
for double functions. These types are supported for all glibc
configurations. The API corresponds exactly to that for _Float128 and
_Float64x. _Float32 aliases to float functions remain to be added in
subsequent patches to complete this process (then there are a few
miscellaneous functions in TS 18661-3 to implement that aren't simply
versions of existing functions for new types).
The patch enables the feature in bits/floatn-common.h, adds symbol
versions and documentation with updates to ABI baselines, and arranges
for the libm functions for the new types to be tested. As with the
_Float64x changes there are some x86 ulps updates because of header
inlines not used for the new types (and one other change to the
non-multiarch libm-test-ulps, which I suppose comes from using a
different compiler version / configuration from when it was last
regenerated).
Tested for x86_64 and x86, and with build-many-glibcs.py, with both

Use long double not double for _Float64 with old GCC if values the same.
If double, long double and _Float64 all have the same set of values,
TS 18661-3 requires the usual arithmetic conversions on long double
and _Float64 to produce _Float64. For this to be the case when
building with a compiler without a distinct _Float64 type, _Float64
must be a typedef for long double, not for double. (_Float32x,
however, must be double in such a case, not long double, because the
usual arithmetic conversions on _Float32x and double must produce
double.)
This patch adjusts the fallback definition of _Float64 and associated
macros accordingly in that case, to fix the build of test-tgmath3 with
GCC 6 for such a configuration. Tested in conjunction with _Float64
changes with build-many-glibcs.py for arm-linux-gnueabi, to make sure
the issue with test-tgmath3 is fixed. Also tested for x86_64.

Add elision tunables
This patch adds several new tunables to control the behavior of
elision on supported platforms[1]. Since elision now depends
on tunables, we should always *compile* with elision enabled,
and leave the code disabled, but available for runtime
selection. This gives us *much* better compile-time testing of
the existing code to avoid bit-rot[2].
Tested on ppc, ppc64, ppc64le, s390x and x86_64.

floor with simple casts.
Also since long == int for 32-bit targets, we can use long instead of
int to avoid 64-bit integer for 64-bit targets.

tilegx: work around vector insn bug in gcc
Avoid an issue in gcc where some of the vector (aka SIMD) ops will
sometimes end up getting wrongly optimized out. We use these
instructions in many of the string implementations. If/when we
have an upstreamed fix for this problem in gcc we can conditionalize
the use of the extended assembly workaround in glibc.

Linux: Implement interfaces for memory protection keys
This adds system call wrappers for pkey_alloc, pkey_free, pkey_mprotect,
and x86-64 implementations of pkey_get and pkey_set, which abstract over
the PKRU CPU register and hide the actual number of memory protection
keys supported by the CPU. pkey_mprotect with a -1 key is implemented
using mprotect, so it will work even if the kernel does not support the
pkey_mprotect system call.
The system call wrapers use unsigned int instead of unsigned long for
parameters, so that no special treatment for x32 is needed. The flags
argument is currently unused, and the access rights bit mask is limited
to two bits by the current PKRU register layout anyway.

Use __floor not floor in sinf.
The new sinf implementation introduced localplt failures for all
platforms where the compiler did not inline the calls to floor
(converted to trunc by machine-independent optimizations). This patch
changes the calls to use __floor as normal in libm.
We can't use the public function names floor / floorf / floorl /
floorf128 in libm code in the absence of appropriate asms to redirect
floor/trunc calls, if not inlined, to use the internal names instead
(while avoiding breaking code building the floor functions themselves)
- while having such asms and then calling the public functions
unconditionally would be desirable for optimization (few architectures
have __floor inlines in math_private.h, and once the built-in function
is used you don't need them), using __floor is the minimum safe fix
for the present test regressions.
Tested with build-many-glibcs.py that this fixes the localplt test
failure for arm-linux-gnueabi.
* sysdeps/ieee754/flt-32/s_sinf.c (SINF_FUNC): Use __floor instead
of floor.

S390: Fix backtrace in vdso functions.
On s390, GDB fails to show the complete backtrace from within vdso
functions.
The macro INTERNAL_VSYSCALL_CALL saves the return address in r14 to r10
before branching to the vdso function. The branch-instruction updates r14
in order to let the vdso function return. Then the original address in r14
is
restored from r10. Unfortunately, there are no cfi-rules and GDB fails.
Furthermore the call of the vdso function does not comply with the s390 ABI
as no stack-frame for the vdso-function is generated.
This patch removes the s390 specific macro INTERNAL_VSYSCALL_CALL
and the common implementation in sysdeps/unix/sysv/linux/sysdep-vdso.h is
used.
Then the vdso function is called via function-pointer and GCC generates a
new stack-frame and emits all needed cfi-rules.
The defines CLOBBER_[0-6] are removed as they were only used in macro
INTERNAL_VSYSCALL_CALL.
The macro INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK is not used on s390.
The only user is power. Thus it is removed from s390 sysdep.h.
ChangeLog:

Use libm_alias_double for remaining powerpc functions.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes the remaining double powerpc functions use
libm_alias_double to define function aliases (with consequent removal
of the need for local compat symbol handling). Previous cleanups
avoid this patch changing installed stripped shared libraries for any
build-many-glibcs.py configuration (there are still some functions in
this patch for which the order of double and float aliases changes
within an individual source file, but in this case this doesn't result
in changes to the final library).
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for all its hard-float powerpc configurations.

Define powerpc64 lroundl compat symbol only once.
sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround.c defines the
lroundl compat symbol, version GLIBC_2_1, twice, once based on llround
and once based on __lround. Those are aliases for each other (llround
weak, __lround strong), but defining it twice does not make sense.
This patch changes it to define the compat symbol once only, matching
how libm_alias_double defines it.
Tested with build-many-glibcs.py for its powerpc64 configurations.

Base powerpc logbl compat symbols on __logb not logb.
Some powerpc logb implementations define a compat symbol for logbl
based on logb, whereas libm_alias_double defines such a compat symbol
based on __logb instead. This difference (logb is weak, __logb isn't)
is enough to result in different installed stripped shared libraries.
The difference in the installed libraries isn't significant, but first
changing the compat_symbol calls helps make it possible to validate a
subsequent change to use libm_alias_double by comparison of libraries,
so this patch does such a preliminary change.
Tested with build-many-glibcs.py for all its hard-float powerpc
configurations.

Ues libm_alias_double for various powerpc functions.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch various powerpc functions use libm_alias_double to
define function aliases (with consequent removal of the need for local
compat symbol handling). (The present patch excludes the changes to
some functions where such changes could result in differences in
installed stripped shared libraries because of changes to the exact
ordering or properties of symbols in individual .os files.)
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for all its hard-float powerpc configurations.

Use libm_alias_double for powerpc fabs, fma.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes powerpc fabs and fma use libm_alias_double
to define function aliases. This brings in automatic symbol
versioning compat handling, so the powerpc32 and powerpc64 wrappers
that added such handling to the generic sysdeps/powerpc/fpu versions
are removed as no longer required (there are no sysdeps directory
ordering issues that would necessitate keeping trivial wrappers
there).
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for all its hard-float powerpc configurations.

Rework m68k libm functions to use declare_mgen_alias.
Many m68k libm functions use their own system to share code between
different types and functions, involving defining macros before
including code for another function (for example, s_atan.c also acts
as a template that can define other functions).
Thes files serving as templates generate function aliases directly
with e.g. "weak_alias (__CONCATX(__,FUNC), FUNC)" in s_atan.c. To be
prepared to generate _Float32, _Float64 and _Float32x function
aliases, this needs changing so that the libm_alias_* macros get used
instead. As the macro to use varies depending on the type, that would
mean additional macros to define in several different places to get
the appropriate alias-generation macro used in each case.
Rather than adding to the m68k-specific mechanisms, this patch
converts the functions in question to use something closer to the
math/ type-generic template mechanism. After this patch, these
functions have m68k-specific templates such as s_atan_template.c, but
those templates use all the same macros as in the math/ templates,
such as FLOAT, M_DECL_FUNC, M_SUF and declare_mgen_alias. There is no
automatic generation of the files such as s_atan.c that include the
appropriate math-type-macros-*.h header and the template file (the
existing automatic generation logic is only applicable for the fixed
set of templates listed in math/ - and sysdeps sources always override
files generated that way), so those files are still checked in, but
they are all the obvious two-line files (with one additional
definition in the case of the expm1 implementations), rather than
making e.g. s_atan.c special.
Functions are only converted where they should have aliases for
_FloatN / _FloatNx types. Those m68k functions that do not generate
public names (those that only generate __ieee754_*, with wrappers
generating the public names, and classification functions that only
exist once per format not once per type so don't get aliases) are
unchanged. However, log1p (public names generated by wrapper) and
significand (not provided for new types so no new aliases needed)
needed changing because they previously included the atan
implementations. Now, s_significand.c is the main implementation for
functions with that prototype and using the old implementation
approach, while log1p includes it in place of atan.
Any further cleanups in this area (which preserve the proper set of
functions getting aliases defined by libm_alias_float and
libm_alias_double) are of course welcome, just not needed for the
goals of this patch.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by the patch.

plural.c: improve reproducibility
There is a subtle non-determinism when building glibc.
This depends on whether the glibc is built using the distibuted
file intl/plural.c or built using the generated file intl/plural.c.
These two files (intl/plural.c generated vs. distributed) are slightly
different, hence we may end up with slightly different libraries.
Originally, having "bison" installed was optional. So if "bison" was
not present, we always built libraries with the distributed plural.c.
If bison was installed, we *** may have *** replaced the distributed
file plural.c with a new plural.c generated from plural.y. if the
timestamps triggered this rule:
plural.c plural.y
$(BISON) $(BISONFLAGS) $@ $^
Given that timestamps are not preserved in GIT repositories, the above
rule is not reliable without explicitly touching plural.c or plural.y.
In other words, the rule may or may not have fired.
In summary: there are two distinct sources of non-determinism:
1. Having "bison" installed or not
2. Having "bison" installed but timestamps poorly defined.
This patch fixes this by requiring "bison" being installed
and by always generating intl/plural.c from intl/plural.y.
(This is achieved by simply removing checked-in intl/plural.c)

* configure.ac (BISON): Require to be present.
* configure: Regenerated.
* intl/Makefile (generated): Add plural.c.

Use libm_alias macros in m68k llrint functions.
Most m68k libm functions share code via sources for one function
including those for another function or type, in a way that will
require significant changes to create function aliases in a way
friendly to adding _FloatN / _FloatNx aliases.
The llrint function implementations, however, use a conventional
separate implementation for each floating-point type. Thus preparing
them for _FloatN / _FloatNx aliases is just a matter of changing them
to include the appropriate headers and use the appropriate macros,
which this patch does. The llrintl changes aren't strictly required,
since m68k long double does not meet the criteria for a _FloatN /
_FloatNx type, but are included anyway to keep consistency between the
implementations for the three types.
Tested with build-many-glibcs.py that installed stripped shared
libraries for m68k-linux-gnu are unchanged by the patch.

Use declare_mgen_alias in m68k templates.
Some m68k libm functions have their own templates replacing the
generic math/ ones but using the type-generic template machinery.
These currently define function aliases directly using weak_alias. In
preparation for additional _FloatN / _FloatNx function aliases, this
patch changes them to use declare_mgen_alias for creating aliases
instead.

x86: Make a space in jmpbuf for shadow stack pointer
To support Shadow Stack (SHSTK) in Intel Control-flow Enforcement
Technology (CET) in setjmp/longjmp, we need to save shadow stack
pointer in jmp_buf. The __saved_mask field in jmp_buf has type
of __sigset_t. On Linux, __sigset_t is defined as
#define _SIGSET_NWORDS (1024 / (8 * sizeof (unsigned long int)))
typedef struct
{
unsigned long int __val[_SIGSET_NWORDS];
} __sigset_t;
which is much bigger than expected by the __sigprocmask system call,
which has
typedef struct {
unsigned long sig[_NSIG_WORDS];
} sigset_t;
For Linux/x86, we can shrink __sigset_t used by __saved_mask in jmp_buf
to add paddings for shadow stack pointer. As long as the new __sigset_t
is not smaller than sigset_t expected by the __sigprocmask system call,
it should work correctly.
This patch adds an internal header file, <setjmpP.h>, to define
__jmp_buf_sigset_t for __saved_mask in jmp_buf for Linux/x86 with a
space to store shadow stack pointer. It verifies __jmp_buf_sigset_t has
the suitable size for the __sigprocmask system call. A run-time test,
tst-saved_mask-1.c, is added to verify that size of __jmp_buf_sigset_t
is sufficient. If its size is too small, the test fails with
rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8)
@0x7fa8aa28effc
0x7fa8aa28effc, NULL, 8) = -1 EFAULT (Bad address)
rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8)
@0x7fa8aa28effc

rt_sigprocmask(SIG_SETMASK, NULL, 0x7fa8aa28effc, 8) = -1 EFAULT (Bad
address)
exit_group(1) = ?

Fix integer overflow in malloc when tcache is enabled [BZ #22375]
When the per-thread cache is enabled, __libc_malloc uses request2size (which
does not perform an overflow check) to calculate the chunk size from the
requested allocation size. This leads to an integer overflow causing malloc
to incorrectly return the last successfully allocated block when called with
a very large size argument (close to SIZE_MAX).
This commit uses checked_request2size instead, removing the overflow.

Remove SPARC lllrint aliases.
The sparc32/sparcv9/fpu/multiarch implementations of llrint / llrintf
have aliases lllrint / lllrintf. No such function is exported from or
used in libm and these aliases should not be there; I expect they
arose accidentally in the course of converting a 64-bit implementation
(where lrint and llrint can be aliases) to a 32-bit llrint
implementation. This patch removes those spurious aliases.
Tested (compilation only) with build-many-glibcs.py for
sparcv9-linux-gnu.

Fix missing sparcv9 --disable-multi-arch fabsl compat symbol (bug 22229).
The --disable-multi-arch case of sparcv9 libm is missing a fabsl
compat symbol for when long double had the same ABI as double. This
patch adds the missing compat symbol to this implementation. As my
fix for other instances of this missing compat symbol postdates the
last release, I'm considering this as being part of bug 22229 that was
missing from my previous fix rather than as a separate issue, and so
as not needing a new bug report in Bugzilla.
Tested (compilation only) with build-many-glibcs.py for
sparcv9-linux-gnu --disable-multi-arch.

Add SPARC --disable-multi-arch builds to build-many-glibcs.py.
While working on SPARC changes to use libm_alias_* I noticed that the
non-multi-arch sparc32/sparcv9/fpu/s_fabs.S was missing compat symbol
support for fabsl. This clearly shows inadequate test coverage, so
this patch adds SPARC --disable-multi-arch builds to
build-many-glibcs.py (the 32-bit one fails testing until that bug is
fixed, the 64-bit one passes testing).
* scripts/build-many-glibcs.py (Context.add_all_configs): Add

instead of âifdef DIACRIT_BACKWARDâ.
The only locale which currently needs backward accents sorting is fr_CA.
Therefore, forward accents sorting should be the default.
Before this patch, backwards accent sorting was the default and all
locales except fr_CA had to use
define DIACRIT_FORWARD
before
copy "iso14651_t1"
Most locales didnât do that and thus got the inappropriate backwards
accents sorting
by accident. Now only the fr_CA locale needs to use
define DIACRIT_BACKWARD
before
copy "iso14651_t1"

sparc: Assume VIS3 support
This patch assumes VIS3 support by binutils, which is supported since
version 2.22. This leads to some code simplification, mostly on
multiarch build where there is only one variant instead of previously
two (whether binutils supports VIS3 instructions or not).
For multiarch files where HAVE_AS_VIS3_SUPPORT was checked and
the default implementation was built with a different name, a new
file with (implementation with -generic appended) is added.

Properly compute offsets of note descriptor and next note [BZ #22370]
A note header has 3 4-bytes fields, followed by note name and note
descriptor. According to gABI, in a note entry, the note name field,
not note name size, is padded for the note descriptor. And the note
descriptor field, not note descriptor size, is padded for the next
note entry. Notes are aligned to 4 bytes in 32-bit objects and 8 bytes
in 64-bit objects.
For all GNU notes, the name is "GNU" which is 4 bytes. They have the
same format in the first 16 bytes in both 32-bit and 64-bit objects.
They differ by note descriptor size and note type. So far, .note.ABI-tag
and .note.gnu.build-id notes are always aligned to 4 bytes. The exsting
codes compute the note size by aligning the note name size and note
descriptor size to 4 bytes. It happens to produce the same value as
the actual note size by luck since the name size is 4 and offset of the
note descriptor is 16. But it will produce the wrong size when note
alignment is 8 bytes in 64-bit objects.
This patch defines ELF_NOTE_DESC_OFFSET and ELF_NOTE_NEXT_OFFSET to
properly compute offsets of note descriptor and next note. It uses
alignment of PT_NOTE segment to support both 4-byte and 8-byte note
alignments in 64-bit objects. To handle PT_NOTE segments with
incorrect alignment, which may lead to an infinite loop, if segment
alignment is less than 4, we treate alignment as 4 bytes since some
note segments have 0 or 1 byte alignment.

benchtests: Expand range of tests names in schema.json
When executing bench-math the benchmark output is invalid with this
error msg:
Invalid benchmark output: 'workload-spec2006.wrf' does not match any of
the regexes: '^[_a-zA-Z0-9]*$¹ or Invalid benchmark output: Additional
properties are not allowed ('workload-spec2006.wrf' was unexpected)
The error was seen when running the test:
workload-spec2006.wrf, 'stack=1024,guard=1' and 'stack=1024,guard=2'.
The problem is that the current regex's do not accept the hyphen, dot, equal

benchmark tests names.

Use libm_alias_float for alpha.
Continuing the preparation for additional _FloatN / _FloatNx function

libm_alias_float macros to define function aliases. In the case of
the ABI compatibility for complex functions, libm_alias_float_other is

argument without the trailing 'f' to facilitate this, and
cfloat_versions dealing with calling libm_alias_float_other (except
for clog10f, which doesn't use that macro because of the complexity
associated with __clog10f also being exported).

Use libm_alias_double for alpha.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes alpha libm function implementations use
libm_alias_double to define function aliases. This also simplifies
the code because the compatibility for long double = double is handled
by libm_alias_double instead of locally in each source file.
Tested with build-many-glibcs.py for alpha-linux-gnu that installed
stripped shared libraries are unchanged by the patch.

Add _Float64x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64x
function aliases on platforms with _Float64x support. (It so happens
the set of such platforms is exactly the same as the set of platforms
with _Float128 support, although on x86_64, x86 and ia32 the _Float64x
format is Intel extended rather than binary128.) The API provided
corresponds exactly to that provided for _Float128, mostly coming from
TS 18661-3. As these functions always alias those for another type
(long double, _Float128 or both), __* function names are not provided,
as in other cases of alias types.
Given the preparation done in previous patches, this one just enables
the feature via Makeconfig and bits/floatn.h, adds symbol versions,
and updates documentation and ABI baselines. The symbol versions are
present unconditionally as GLIBC_2.27 in the relevant Versions files,
as it's OK for those to specify versions for functions that may not be
present in some configurations; no additional complexity is needed
unless in future some configuration gains support for this type that
didn't have such support in 2.27. The Makeconfig additions for ia64
and x86 aren't strictly needed, as those configurations also get
float64x-alias-fcts definitions from
sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given
that _Float64x is not _Float128 for those configurations.
A libm-test-ulps update for x86 is included. This is because
bits/mathinline.h does not have _Float64x support added and for two
functions the use of out-of-line functions results in increased ulps
(ifloat64x shares ulps with ildouble / ifloat128 as appropriate).
Given that we'd like generally to eliminate bits/mathinline.h
optimizations, preferring to have such optimizations in GCC instead,
it seems reasonable not to add such support there for new types. GCC
support for _FloatN / _FloatNx built-in functions is limited, but has
been improved in GCC 8, and at some point I hope the full set of libm
built-in functions in GCC, and other optimizations with
per-floating-type aspects, will be enabled for all _FloatN / _FloatNx
types.
Tested for x86_64 and x86, and with build-many-glibcs.py, with both
GCC 6 and GCC 7.

Support _Float64x in libm_alias macros.
This patch adds support for libm_alias_ldouble and libm_alias_float128
to create *f64x function aliases when appropriate.
Making such aliases work for functions defined in assembly sources
requires adding some semicolons after weak_alias calls in alias macro
definitions. For C, semicolons are already present in the macros
called when required, but a GNU C extension allows excess semicolons
at file scope in a source file (and glibc already uses this), so it is
OK to have extra semicolons present in the macro definitions. For
assembly sources, making multiple alias macro calls from a single
macro expansion means there are no newlines between the calls, so an
explicit separator is needed. If hppa were to have .S sources in
libm, a more complicated approach would be needed that used
ASM_LINE_SEP when building assembly sources but not for C, but right
now there are no such sources so just using a semicolon (as already
present unconditionally in some such macro expansions) suffices.

patches.

Make min_of_type_ macros function-like.
math_private.h uses __MATH_TG in defining the min_of_type macro used
within libm, with min_of_type_<suffix> macros for each type. This
runs into problems with __MATH_TG expansions used with additional
_FloatN and _FloatNx type support, because those can end up
macro-expanding the FUNC argument to __MATH_TG before it gets
concatenated with a suffix - meaning that min_of_type_ can't
simultaneously be the macro name for double, and a prefix to other
macro names, since the latter case requires such premature macro
expansion not to occur. (This is not a problem for the uses of
__MATH_TG in installed headers because FUNC there is a function name
in the implementation namespace, and the suffixes themselves don't get
macro-expanded.)
This patch fixes the problem by making min_of_type_<suffix> macros
function-like, so no macro expansion occurs when min_of_type_ is
expanded on its own as a macro argument, only later when followed by
() after expansion.
Tested for x86_64, including in conjunction with _Float64x support
patches.

creating the internal types for combinations of long double with
_Float64 and _Float64x, so resulting in output that did not compile
when glibc support for those types was enabled. This patch adds the
missing argument so that the tests properly compile in that case.
Tested for x86_64, including in conjunction with _Float64x support
patches.
* math/gen-tgmath-tests.py (Type.init_types): Pass suffix argument
for combinations of long double with _Float64 and _Float64x.

Use libm_alias_ldouble macros in sysdeps/ia64/fpu.
Continuing the preparation for additional _FloatN / _FloatNx aliases,
this patch makes long double functions in sysdeps/ia64/fpu use
libm_alias_ldouble macros, so that they can have _Float64x aliases
added in future.

included from libm-symbols.h (and the expectation that other

and libm_alias_ldouble_other then being used in most cases to define
aliases for any additional types (currently the empty set). Functions
that used weak_alias are converted to use libm_alias_ldouble.

The system call is somewhat obscure because it is closely related

No emulation is provided. Except for the name of the
/proc/self/fd links, it would be possible to implement an
approximation using O_TMPFILE and tmpfs, but this does not appear

Fix p_secstodate overflow handling (bug 22463).
The resolv/res_debug.c function p_secstodate (which is a public
function exported from libresolv, taking an unsigned long argument)
does:
struct tm timebuf;
time = __gmtime_r(&clock, &timebuf);
time->tm_year += 1900;
time->tm_mon += 1;
sprintf(output, "%04d%02d%02d%02d%02d%02d",
time->tm_year, time->tm_mon, time->tm_mday,
time->tm_hour, time->tm_min, time->tm_sec);
If __gmtime_r returns NULL (because the year overflows the range of
int), this will dereference a null pointer. Otherwise, if the
computed year does not fit in four characters, this will cause a
buffer overrun of the fixed-size 15-byte buffer. With current GCC
mainline, there is a compilation failure because of the possible
buffer overrun.
I couldn't find a specification for how this function is meant to
behave, but Paul pointed to RFC 4034 as relevant to the cases where
this function is called from within glibc. The function's interface
is inherently problematic when dates beyond Y2038 might be involved,
because of the ambiguity in how to interpret 32-bit timestamps as such
dates (the RFC suggests interpreting times as being within 68 years of
the present date, which would mean some kind of interface whose
behavior depends on the present date).
This patch works on the basis of making a minimal fix in preparation
for obsoleting the function. The function is made to handle times in
the interval [0, 0x7fffffff] only, on all platforms, with <overflow>
used as the output string in other cases (and errno set to EOVERFLOW
in such cases). This seems to be a reasonable state for the function
to be in when made a compat symbol by a future patch, being compatible
with any existing uses for existing timestamps without trying to work
for later timestamps. Results independent of the range of time_t also
simplify the testcase.
I couldn't persuade GCC to recognize the ranges of the struct tm
fields by adding explicit range checks with a call to
__builtin_unreachable if outside the range (this looks similar to
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80776>), so having added
a range check on the input, this patch then disables the
-Wformat-overflow= warning for the sprintf call (I prefer that to the
use of strftime, as being more transparently correct without knowing
what each of %m and %M etc. is).
I do not know why this build failure should be new with mainline GCC
(that is, I don't know what GCC change might have introduced it, when
the basic functionality for such warnings was already in GCC 7).
I do not know if this is a security issue (that is, if there are
plausible ways in which a date before -999 or after 9999 from an
untrusted source might end up in this function). The system clock is
arguably an untrusted source (in that e.g. NTP is insecure), but
probably not to that extent (NTP can't communicate such wild
timestamps), and uses from within glibc are limited to 32-bit inputs.
Tested with build-many-glibcs.py that this restores the build for arm
with yesterday's mainline GCC. Also tested for x86_64 and x86.

Avoid use of strlen in getlogin_r (bug 22447).
Building glibc with current mainline GCC fails, among other reasons,
because of an error for use of strlen on the nonstring ut_user field.
This patch changes the problem code in getlogin_r to use __strnlen
instead. It also needs to set the trailing NUL byte of the result
explicitly, because of the case where ut_user does not have such a
trailing NUL byte (but the result should always have one).

S390: Add cfi information for start routines in order to stop unwinding.
GDB failed to detect the outermost frame while showing the backtrace
within a thread:
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
Before this patch, the start routines like thread_start had no cfi
information.
GDB is then using the prologue unwinder if no cfi information is available.
This unwinder tries to unwind r15 and stops e.g. if r15 was updated or
on some jump-instructions.
On older glibc-versions (before commit "Remove cached PID/TID in clone"
c579f48edba88380635ab98cb612030e3ed8691e), the thread_start function used
such a jump-instruction and GDB did not fail with an error.
This patch adds cfi information for _start, thread_start and
__makecontext_ret

Remove attribute_hidden for wchar ifunc symbols.
On s390 (31bit) various debug/tst-*chk* testcases are failing as the tests
are ending with a segmentation fault.
One test is e.g. calling wcsnrtombs in debug/tst-chk1.c:1549.
The function wcsnrtombs itself calls __wcsnlen. This function is called via
PLT! The PLT-stub itself loads the address from GOT (r12 is assumed to be
the GOT-pointer). In this case the loaded address is zero and the following
branch leads to the segmentation fault.
Due to the attribute_hidden in commit
44af8a32c341672b5160fdc2839767e9a837ad26
"Mark internal wchar functions with attribute_hidden [BZ #18822]"
for e.g. the __wcsnlen function, r12 is not loaded with the GOT-pointer
in wcsnrtombs.
On s390x (64bit), this __wcsnlen call is also using the PLT-stub. But it is
not failing as the GOT-pointer is setup with larl-instruction by the
PLT-stub
itself.
Note: On s390x/s390, __wcsnlen is an IFUNC symbol.
On x86_64, __wcsnlen is also an IFUNC symbol and is called via PLT, too.
Further IFUNC symbols on s390 which were marked as hidden by the mentioned
commit are: __wcscat, __wcsncpy, __wcpncpy, __wcschrnul.
This patch removes the attribute_hidden in wchar.h.
Then the compiler setups e.g. r12 on s390 in order to call __wcsnlen via
PLT.
ChangeLog:
* include/wchar.h (__wcsnlen, __wcscat, __wcsncpy, __wcpncpy,
__wcschrnul): Remove attribute_hidden.

regex: don't assume uint64_t or uint32_t
This avoids -Werror=overflow errors for 32-bit systems in
the 64-bit case. Problem reported by Joseph Myers in:
https://sourceware.org/ml/libc-alpha/2017-11/msg00694.html
Also, when this code is used in Gnulib it ports to platforms
that lack uint64_t and uint32_t. The C standard doesn't guarantee
them, and on some 32-bit compilers there is no uint64_t.
Problem reported by Gianluigi Tiesi in:
http://lists.gnu.org/archive/html/bug-gnulib/2012-03/msg00154.html

aarch64: Optimized memset for falkor
The generic memset reads dczid_el0 on every memset. This has a
significant impact on falkor for a range of sizes because reading
dczid_el0 is slow.
The DZP bit in the dczid_el0 register does not change dynamically, so
it is safe to read once during program startup. With this patch
dczid_el0 is read once during startup and zva_size is cached. This is
used to invoke the falkor-specific memset; the generic memset routine
remains unchanged.
The gains due to this are significant for falkor, with run time
reductions as high as 48%. Here's a sample from the falkor tests:
Function: memset

benchtests: Fix walking sizes and directions for *-walk benchmarks
Make the walking benchmarks walk only backwards since copying both

Support bits/floatn.h inclusion from .S files.
Further _FloatN / _FloatNx type alias support will involve making
architecture-specific .S files use the common macros for libm function
aliases. Making them use those macros will also serve to simplify
existing code for aliases / symbol versions in various cases, similar
to such simplifications for ldbl-opt code.
The libm-alias-*.h files sometimes need to include <bits/floatn.h> to
determine which aliases they should define. At present, this does not
work for inclusion from .S files because <bits/floatn.h> can define
typedefs for old compilers. This patch changes all the
<bits/floatn.h> and <bits/floatn-common.h> headers to include
__ASSEMBLER__ conditionals. Those conditionals disable everything
related to C syntax in the __ASSEMBLER__ case, not just the problem
typedefs, as that seemed cleanest. The __HAVE_* definitions remain in
the __ASSEMBLER__ case, as those provide information that is required
to define the correct set of aliases.
Tested with build-many-glibcs.py for a representative set of
configurations (x86_64-linux-gnu i686-linux-gnu ia64-linux-gnu
powerpc64le-linux-gnu mips64-linux-gnu-n64 sparc64-linux-gnu) with GCC
6. Also tested with GCC 6 for i686-linux-gnu in conjunction with
changes to use alias macros in .S files.

aarch64: Fix f{max,min}{f} build for GCC 4.9 and 5
GCC 4.9 and 5 do not generate a correct f{max,min}nm instruction for
__builtin_{fmax,fmin}{f} without -ffinite-math-only. It is clear a
compiler issue since the instruction can handle NaN and Inf correctly
and GCC6+ does not show this issue.
We can backport a fix to GCC 5, raise the minimum required GCC version
for aarch64 (since GCC 4.9 branch is now closed [1]) and/or add
configure check to check for this issue. However I think
-ffinite-math-only should be safe for these specific implementations
and it is a simpler solution.

[1]: 15e9a4f introduced a semantic that, under certain failure
conditions, ttyname sets errno=ENODEV, where previously it didn't
set errno; it's not quite fair to hold "before 15e9a4f" ttyname to
those new semantics. This testcase actually fails, but would have
passed if we tested for the old the semantics.
Each of the failing tests before 15e9a4f are all essentially the same bug:
that
it returns a PTY slave with the correct minor device number, but from the
wrong
devpts filesystem instance.
15e9a4f sought to fix this, but missed several of the cases that can cause
this
to happen, and also broke the case where both the erroneous PTY and the
correct
PTY exist.

linux ttyname{_r}: Don't bail prematurely [BZ #22145]
Commit 15e9a4f378c8607c2ae1aa465436af4321db0e23 introduced logic for
ttyname()
sending back ENODEV to signal that we can't get a name for the TTY because
we
inherited it from a different mount namespace.
However, just because we inherited it from a different mount namespace and
it
isn't available at its original path, doesn't mean that its name is
unknowable;
we can still try to find it by allowing the normal fall back on iterating
through devices.
An example scenario where this happens is with "/dev/console" in containers.
It's a common practice among container managers to allocate a PTY
master/slave
pair in the host's mount namespace (the slave having a path like
"/dev/pty/$X"),
bind mount the slave to "/dev/console" in the container's mount namespace,
and
send the slave FD to a process in the container. Inside of the
container, the slave-end isn't available at its original path
("/dev/pts/$X"),
since the container mount namespace has a separate devpts instance from the
host
(that path may or may not exist in the container; if it does exist, it's
not the
same PTY slave device). Currently ttyname{_r} sees that the file at the
original "/dev/pts/$X" path doesn't match the FD passed to it, and fails
early
and gives up, even though if it kept searching it would find the TTY at
"/dev/console". Fix that; don't have the ENODEV path force an early return
inhibiting the fall-back search.
This change is based on the previous patch that adds use of is_mytty in
getttyname and getttyname_r. Without that change, this effectively reverts
15e9a4f, which made us disregard the false similarity of file pointed to by
"/proc/self/fd/$Y", because if it doesn't bail prematurely then that file
("/dev/pts/$X") will just come up again anyway in the fall-back search.

linux ttyname{_r}: Make tty checks consistent
In the ttyname and ttyname_r routines on Linux, at several points it needs
to
check if a given TTY is the TTY we are looking for. It used to be that this
check was (to see if `maybe` is `mytty`):
__xstat64(_STAT_VER, maybe_filename, &maybe) == 0
#ifdef _STATBUF_ST_RDEV
&& S_ISCHR(maybe.st_mode) && maybe.st_rdev == mytty.st_rdev
#else
&& maybe.st_ino == mytty.st_ino && maybe.st_dev == mytty.st_dev
#endif
This check appears in several places.
Then, one of the changes made in commit
15e9a4f378c8607c2ae1aa465436af4321db0e23
was to change that check to:
__xstat64(_STAT_VER, maybe_filename, &maybe) == 0
#ifdef _STATBUF_ST_RDEV
&& S_ISCHR(maybe.st_mode) && maybe.st_rdev == mytty.st_rdev
#endif
&& maybe.st_ino == mytty.st_ino && maybe.st_dev == mytty.st_dev
That is, it made the st_ino and st_dev parts of the check happen even if we
have
the st_rdev member. This is an important change, because the kernel allows
multiple devpts filesystem instances to be created; a device file in one
devpts
instance may share the same st_rdev with a file in another devpts instance,
but
they aren't the same file.
This check appears twice in each file (ttyname.c and ttyname_r.c), once (in
ttyname and __ttyname_r) to check if a candidate file found by inspecting
/proc
is the desired TTY, and once (in getttyname and getttyname_r) to check if a
candidate file found by searching /dev is the desired TTY. However, 15e9a4f
only updated the checks for files found via /proc; but the concern about
collisions between devpts instances is just as valid for files found via
/dev.
So, update all 4 occurrences the check to be consistent with the version of
the
check introduced in 15e9a4f. Make it easy to keep all 4 occurrences of the
check consistent by pulling it in to a static inline function, is_mytty.

Use __builtin_tgmath in tgmath.h with GCC 8 (bug 21660).
GCC mainline now supports __builtin_tgmath to allow <tgmath.h> macro
implementations that expand their arguments only once, so avoiding
exponential blowup in the size of macro expansions when calls to those
macros are nested in arguments to those macros.
This patch makes glibc's tgmath.h support using __builtin_tgmath, as a
much simpler and more efficient alternative to the existing
implementation. (As a side effect, the new feature would make it much
more practical to support decimal floating point in <tgmath.h> with
new compilers; currently, libdfp does not provide a <tgmath.h>
implementation, and making decimal arguments cause integer arguments
to be considered of type _Decimal64 instead of double would have been
very problematic in the old implementation.)
Tested for x86_64 (with GCC mainline).

Fix string/tester.c build with GCC 8.
GCC 8 warns about more cases of string functions truncating their
output or not copying a trailing NUL byte.
This patch fixes testsuite build failures caused by such warnings in
string/tester.c. In general, the warnings are disabled around the
relevant calls using DIAG_* macros, since the relevant cases are being
deliberately tested. In one case, the warning is with
-Wstringop-overflow= instead of -Wstringop-truncation; in that case,
the conditional is __GNUC_PREREQ (7, 0) (being the version where
-Wstringop-overflow= was introduced), to allow the conditional to be
removed sooner, since it's harmless to disable the warning for a
GCC version where it doesn't actually occur. In the case of warnings
for strncpy calls in test_memcmp, the calls in question are changed to
use memcpy, as they don't copy a trailing NUL and the point of that
code is to test memcmp rather than strncpy.
Tested (compilation) with GCC 8 for x86_64-linux-gnu with
build-many-glibcs.py (in conjunction with Martin's patch to allow
glibc to build).
* string/tester.c (test_stpncpy): Disable -Wstringop-truncation
for stpncpy calls for GCC 8.
(test_strncat): Disable -Wstringop-truncation warning for strncat
calls for GCC 8. Disable -Wstringop-overflow= warning for one
strncat call for GCC 7.
(test_strncpy): Disable -Wstringop-truncation warning for strncpy
calls for GCC 8.
(test_memcmp): Use memcpy instead of strncpy for calls not copying
trailing NUL.

ld.so: Add architecture specific fields
To support Intel Control-flow Enforcement Technology (CET) run-time
control:
1. An architecture specific field in the writable ld.so namespace is
needed to indicate if CET features are enabled at run-time.
2. An architecture specific field in struct link_map is needed if
CET features are enabled in an ELF module.
This patch adds dl-procruntime.c to the writable ld.so namespace and
link_map.h to struct link_map.
Tested with build-many-glibcs.py.

Handle more _FloatN, _FloatNx types in include/float.h.
Continuing the preparation for additional _FloatN / _FloatNx type
support, this patch adds support in include/float.h. This header
defines macros for _Float128 properties when using compilers before
GCC 7 that lack those macros in <float.h>. For testing _Float32 /
_Float64 / _Float32x / _Float64x functions with older compilers, such
macros need to be defined for those types as well; for the older
compilers, those types will always be typedefs for another type, so
the definitions can be in terms of the macros for that other type.

Handle more _FloatN, _FloatNx types in type-generic strtod tests.
Continuing the preparation for additional _FloatN / _FloatNx type
support, this patch adds support to type-generic strtod tests.
GEN_STRTOD_TEST_FOREACH and STRTOD_TEST_FOREACH are made to handle the
full set of such types. tst-strtod-round-skeleton.c is updated for
those types it can handle without needing changes to the generator
(i.e. those types that have already-handled formats).

nptl: Define __PTHREAD_MUTEX_{NUSERS_AFTER_KIND,USE_UNION}
This patch adds two new internal defines to set the internal
pthread_mutex_t layout required by the supported ABIS:
1. __PTHREAD_MUTEX_NUSERS_AFTER_KIND which control whether to define
__nusers fields before or after __kind. The preferred value for
is 0 for new ports and it sets __nusers before __kind.
2. __PTHREAD_MUTEX_USE_UNION which control whether internal __spins and
__list members will be place inside an union for linuxthreads
compatibility. The preferred value is 0 for ports and it sets
to not use an union to define both fields.
It fixes the wrong offsets value for __kind value on x86_64-linux-gnu-x32.

nptl: Change tst-typesizes to _Static_assert
Instead of rely on runtime check to assure correct pthread types
size a better strategy would use _Static_assert to trigger an error
on build time (and thus allowing to check to potentially ABI breakage
on cross-compiling make check).
This patch moves nptl/tst-typesizes.c to libpthread build time on
each specific initialization routine and also remove some runtime
redundant asserts for the same type sizes.

nptl: Add tests for internal pthread_mutex_t offsets
This patch adds a new build test to check for internal fields
offsets for user visible internal field. Although currently
the only field which is statically initialized to a non zero value
is pthread_mutex_t.__data.__kind value, the tests also check the
offset of __kind, __spins, __elision (if supported), and __list
internal member. A internal header (pthread-offset.h) is added
to each major ABI with the reference value.

arm: Implement memchr ifunc selection in C
This patch refactor ARM memchr ifunc selector to a C implementation.
No functional change is expected, including ifunc resolution rules.
It also reorganize the ifunc options code:
1. The memchr_impl.S is renamed to memchr_neon.S and multiple
compilation options (which route to armv6t2/memchr one) is
removed. The code to build if __ARM_NEON__ is defined is
also simplified.
2. A memchr_noneon is added (which as build along previous ifunc
resolution) and includes the armv6t2 direct.
3. Same as 2. for loader object.
Alongside the aforementioned changes, it also some cleanus:
- Internal memchr definition (__GI_memcpy) is now a hidden
symbol.
- No need to create hidden definition for the ifunc variants.

Do not declare _Float128 support for powerpc64le -mlong-double-64 (bug
22402).
The powerpc bits/floatn.h declares _Float128 support to be present
when the compiler supports it for powerpc64le. However, in the case
where -mlong-double-64 is used, __MATH_TG does not actually support
_Float128; it only supports _Float128 in the distinct-long-double
case.
This shows up as a build failure when building glibc mainline with GCC
mainline, given the recently added sanity check in math.h for
configurations supported by __MATH_TG, as the compat code for
-mlong-double-64 fails to build. However, the bug was logically
present before that change (including in 2.26), just less visible.
This patch fixes the build failure by declaring _Float128 to be
unsupported in that case. (Of course this can't actually stop users
calling the type-generic macros with _Float128 arguments with
-mlong-double-64, just as they could be called with other unsupported
types on other platforms, but perhaps makes it less likely by making
all the type-specific _Float128 interfaces invisible in that case.)
Tested compilation for powerpc64le with build-many-glibcs.py.

Handle more _FloatN, _FloatNx types in __MATH_TG.
Continuing the preparation for additional _FloatN / _FloatNx type

Various unhandled cases, which do not correspond to any current glibc
configuration, have explicit #errors added. _Float32 and _Float64x
are then handled appropriately in the _Generic case, which is the only
one, other than the cases where use of sizeof is sufficient, where
they should ever be explicit types at the language level instead of
typedefs. There is no need to handle _Float64 or _Float32x explicitly
there because the default case calling a double function is correct
for those types.

Handle more _FloatN, _FloatNx types in tgmath.h.
Continuing the preparation for additional _FloatN / _FloatNx type
support, this patch improves how <tgmath.h> handles such types.
Use of #error is added for cases of distinct types that are not
supported by the header, to indicate that additional work on the
header would be needed if, for example, _Float16 support were added to
glibc. Given that #error, types with the same format as other types
are handled automatically by the sizeof-based logic, so the only case
needing special handling is that where _Float64x exists, has the same
format as _Float128, does not have the same format as long double, and
is not a typedef for _Float128. In this case (which will apply for
powerpc64le once _Float64x support is added to glibc), the
__builtin_types_compatible_p calls testing for _Float128 need
corresponding calls testing for _Float64x, which this patch adds.

relocs in DT_REL*, so elf_machine_lazy_rel is not called on them at all.

aarch64: Disable lazy symbol binding of TLSDESC
Always do TLS descriptor initialization at load time during relocation
processing to avoid barriers at every TLS access. In non-dlopened shared
libraries the overhead of tls access vs static global access is > 3x
bigger when lazy initialization is used (_dl_tlsdesc_return_lazy)
compared to bind-now (_dl_tlsdesc_return) so the barriers dominate tls
access performance.
TLSDESC relocs are in DT_JMPREL which are processed at load time using
elf_machine_lazy_rel which is only supposed to do lightweight
initialization using the DT_TLSDESC_PLT trampoline (the trampoline code
jumps to the entry point in DT_TLSDESC_GOT which does the lazy tlsdesc
initialization at runtime). This patch changes elf_machine_lazy_rel
in aarch64 to do the symbol binding and initialization as if DF_BIND_NOW
was set, so the non-lazy code path of elf/do-rel.h was replicated.
The static linker could be changed to emit TLSDESC relocs in DT_REL*,
which are processed non-lazily, but the goal of this patch is to always
guarantee bind-now semantics, even if the binary was produced with an
old linker, so the barriers can be dropped in tls descriptor functions.
After this change the synchronizing ldar instructions can be dropped
as well as the lazy initialization machinery including the DT_TLSDESC_GOT
setup.
I believe this should be done on all targets, including ones where no
barrier is needed for lazy initialization. There is very little gain in
optimizing for large number of symbolic tlsdesc relocations which is an
extremely uncommon case. And currently the tlsdesc entries are only
readonly protected with -z now and some hardennings against writable
JUMPSLOT relocs don't work for TLSDESC so they are a security hazard.
(But to fix that the static linker has to be changed.)

Include bits/cmathcalls.h for more _FloatN, _FloatNx types.
Continuing the preparation for additional _FloatN / _FloatNx type
support, this patch arranges for <bits/cmathcalls.h> to be included by
<complex.h> for each such type under conditions and with macros
defined corresponding to those used for _Float128.

Clean up complex.h handling of float128.
This patch cleans up the way complex.h handles inclusion of
bits/cmathcalls.h for float128. The inclusion was between those for
the types float and long double; the patch moves it after that for
long double, matching how bits/mathcalls.h and bits/math-finite.h
inclusions are ordered. There is no need for the undefine and define
of _Mdouble_complex_ to be conditional, since __CFLOAT128 is always
defined by bits/floatn.h when _Float128 is supported, so the patch
removes the unnecessary conditionals.
Tested for x86_64.

[(__HAVE_DISTINCT_FLOAT128 || (__HAVE_FLOAT128 && !LIBC))

Remove useless #ifdefs from Linux sig*.c syscalls
sigprocmask.c, sigtimedwait.c, sigwait.c and sigwaitinfo.c files from
sysdeps/unix/sysv/linux include nptl-signals.h via nptl/pthreadP.h,
and so SIGCANCEL and SIGSETXID become defined unconditionally. But
later in the code, there are some checks weither symbols defined,
which is useless. This patch removes useless checks.

Adjust __MATH_EVAL_FMT2 definition to handle _Float16 better.
Continuing the preparation for additional _FloatN / _FloatNx type
support, this patch adds an additional case in the definition of
__MATH_EVAL_FMT2, as used in defining iseqsig: when
__FLT_EVAL_METHOD__ is 0 or 32, it adds 0.0f to the arguments, so that
the correct function would be selected in the case of _Float16
arguments with excess precision (were glibc to support _Float16, which
of course __MATH_TG and other facilities do not at present - and
_Float16 support is not part of what this patch series is aiming for,
but this particular fix is simple so is included anyway).

Remove _Mlong_double_ etc. macros.
math.h has a macro _Mlong_double_ for the type to use when declaring
long double functions, and similar macros for other types.
math/Makefile uses -D_Mlong_double_=double in the case of long double
having the same ABI as double.
This originates with:
Mon Jul 8 13:37:40 1996 Roland McGrath <address@hidden>
* math/math.h (_Mfloat_, _Mlong_double_): New macros, defined iff
not
already defined to float, long double. Use those macros for
_Mdouble_
defns when including mathcalls.h.
* math/Makefile [$(long-double-fcts) != yes] (CPPFLAGS): Append
-D_Mlong_double_=double.
However, math.h stopped declaring long double functions in the case of
long double having the same ABI as double (and thus probably stopped
actually needing the Makefile definition of _Mlong_double_) with:
1998-11-05 Ulrich Drepper <address@hidden>
* math/math.h: Unconditionally include bits/mathdef.h. Declare
long double functions only if __NO_LONG_DOUBLE_MATH is not
defined.
* sysdeps/generic/bits/mathdef.h: Define only if __USE_ISOC9X.
Define __NO_LONG_DOUBLE_MATH.
* sysdeps/m68k/fpu/bits/mathdef.h: Define only if __USE_ISOC9X.
* sysdeps/i386/fpu/bits/mathdef.h: Likewise.
The declarations were since restored for compiling user code, but
remain absent when _LIBC is defined, which is sufficient to avoid
problems declaring function aliases of incompatible types. Thus the
indirection through the _Mlong_double_ macro is not needed (probably

i586: Use conditional branches in strcpy.S [BZ #22353]
i586 strcpy.S used a clever trick with LEA to implement jump table:
/* ECX has the last 2 bits of the address of source - 1. */
andl $3, %ecx
call 2f
2: popl %edx
/* 0xb is the distance between 2: and 1:. */
leal 0xb(%edx,%ecx,8), %ecx
jmp *%ecx
.align 8
1: /* ECX == 0 */
orb (%esi), %al
jz L(end)
stosb
xorl %eax, %eax
incl %esi
/* ECX == 1 */
orb (%esi), %al
jz L(end)
stosb
xorl %eax, %eax
incl %esi
/* ECX == 2 */
orb (%esi), %al
jz L(end)
stosb
xorl %eax, %eax
incl %esi
/* ECX == 3 */
L(1): movl (%esi), %ecx
leal 4(%esi),%esi
This fails if there are instruction length changes before L(1):. This
patch replaces it with conditional branches:
cmpb $2, %cl
je L(Src2)
ja L(Src3)
cmpb $1, %cl
je L(Src1)
L(Src0):
which have similar performance and work with any instruction lengths.
Tested on i586 and i686 with and without --disable-multi-arch.

Add _FloatN, _FloatNx M_* constants.
Continuing the preparation for additional _FloatN / _FloatNx type
support, this patch adds M_* constants for such types. The decimal
expansions used are all the same as used for _Float128; there's no
need to reduce the precision used. In the case of _Float128x, #error
is used because the constants would need additional precision, but how
much is needed would depend on the actual _Float128x format used, so
it's not possible to add header support simply as part of code that
handles all _FloatN / _FloatNx types similarly.

Correct the size of _nl_value_type_LC_... arrays.
There were several problems with checking the array size in the past,
for example BZ#356, caused by incorrectly assuming that every locale
token represents one element. In fact, if a token represented
a subarray, for example an array of month names or characters category
and it appeared at the end of the array the compiler assumed that
the array ends just after the first element of the subarray.
A workaround used in the past was to skip some categories while testing,
for example LC_CTYPE. Now when we are about to add alternative month
names to LC_TIME (BZ#10871) this will fail again.

localedef: Add --no-warnings/--warnings option
From localedef --help:
Output control:
...
--no-warnings=<warnings> Comma-separated list of warnings to
disable;
supported warnings are: ascii, intcurrsym
...
--warnings=<warnings> Comma-separated list of warnings to enable;
supported warnings are: ascii, intcurrsym
Locales using SHIFT_JIS and SHIFT_JISX0213 character maps are not ASCII
compatible. In order to build locales using these character maps, and
have localedef exit with a status of 0, we add new option to localedef
to disable or enable specific warnings. The options are --no-warnings
and --warnings, to disable and enable specific warnings respectively.
The options take a comma-separated list of warning names. The warning
names are taken directly from the generated warning. When a warning
that can be disabled is issued it will print something like this: foo is
not defined [--no-warnings=foo]
For the initial implementation we add two controllable warnings; first
'ascii' which is used by the localedata installation makefile target to
install SHIFT_JIS and SHIFT_JISX0213-using locales without error; second
'intcurrsym' which allows a program to use a non-standard international
currency symbol without triggering a warning. The 'intcurrsym' is
useful in the future if country codes are added that are not in our
current ISO 4217 list, and the user wants to avoid the warning. Having
at least two warnings to control gives an example for how the changes
can be extended to more warnings if required in the future.
These changes allow ja_JP.SHIFT_JIS and ja_JP.SHIFT_JISX0213 to be
compiled without warnings using --no-warnings=ascii. The
localedata/Makefile $(INSTALL-SUPPORTED-LOCALES) target is adjusted to
automatically add `--no-warnings=ascii` for such charmaps, and likewise
localedata/gen-locale.sh is adjusted with similar logic.
v2: Bring verbose, be_quiet, and all warning control booleans into
record-status.c, and compile this object file to be used by locale,
iconv, and localedef. Any users include record-status.h.
v3: Fix an instance of boolean coercion in set_warning().

After the transition to generating a distinct file for Unicode ctype

powerpc: Replace lxvd2x/stxvd2x with lvx/stvx in P7's memcpy/memmove
POWER9 DD2.1 and earlier has an issue where some cache inhibited
vector load traps to the kernel, causing a performance degradation. To
handle this in memcpy and memmove, lvx/stvx is used for aligned
addresses instead of lxvd2x/stxvd2x.
Reference: https://patchwork.ozlabs.org/patch/814059/
* sysdeps/powerpc/powerpc64/power7/memcpy.S: Replace
lxvd2x/stxvd2x with lvx/stvx.

Update x86 fix-fp-int-compare-invalid.h for GCC 8.
The glibc implementation of iseqsig relies on ordered comparison
operators raising the "invalid" exception for quiet NaN operands, with
a workaround on platforms where a GCC bug means that exception is not
raised. For x86, that bug has now been fixed for GCC 8, so this patch
disables the workaround in that case. If and when the corresponding
bugs for powerpc and s390 are fixed, the headers for those platforms
should of course be updated similarly.
Tested for x86_64 and x86, including with GCC mainline. Note that
other failures appear with GCC mainline because of spurious use of
ordered comparison instructions for unordered operations
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82692>.
* sysdeps/x86/fpu/fix-fp-int-compare-invalid.h

posix: Do not use WNOHANG in waitpid call for Linux posix_spawn
As shown in some buildbot issues on aarch64 and powerpc, calling
clone (VFORK) and waitpid (WNOHANG) does not guarantee the child
is ready to be collected. This patch changes the call back to 0
as before fe05e1cb6d64 fix.
This change can lead to the scenario 4.3 described in the commit,
where the waitpid call can hang undefinitely on the call. However
this is also a very unlikely and also undefinied situation where
both the caller is trying to terminate a pid before posix_spawn
returns and the race pid reuse is triggered. I don't see how to
correct handle this specific situation within posix_spawn.
Checked on x86_64-linux-gnu, aarch64-linux-gnu and
powerpc64-linux-gnu.
* sysdeps/unix/sysv/linux/spawni.c (__spawnix): Use 0 instead of
WNOHANG in waitpid call.

size by userspace. This typically is the same as the L1 cache line
size, but that may not always be true. It could be a higher level
cache line size as long as cache cleaning and invalidation work
correctly with that line size in userspace. The falkor core for
example reports the L2 line size as the dcache line size in CTR_EL0
while also reporting the correct L1 dcache line size via CCSIDR_EL1.

__ceil (double x)
{
double result;
asm ("frintp\t%d0, %d1" :
"=w" (result) : "w" (x) );
return result;

PowerPC64 power8 strncpy cfi fixes
cfi info for stack adjust needs to be on the insn doing the adjust.
cfi describing register saves can be anywhere after the save insn but
before the reg is altered. Fewer locations with cfi result in smaller
cfi programs and possibly slightly faster exception handling. Thus
the LR cfi_offset move.
The idea behind ajusting sp after restoring regs is to break a
register dependency chain, in this case not be using r1 immediately
after it is modified.
The missing LR cfi_restore meant that code after the blr,
unaligned_lt_16 and other labels, would have cfi that said LR was at
cfa+16, but that code is reached without LR being saved.

Add bits/floatn.h defines for more _FloatN / _FloatNx types.
The bits/floatn.h header currently only has defines relating to
_Float128. This patch adds defines relating to other _FloatN /
_FloatNx types.
The approach taken is to add defines for all _FloatN / _FloatNx types
known to GCC, and to put them in a common bits/floatn-common.h header
included at the end of all the individual bits/floatn.h headers. If
in future some defines become different for different glibc
configurations, they will move out into the separate bits/floatn.h
headers.
Some defines are expected always to be the same across glibc ports.
Corresponding defines are nevertheless put in this header. The intent
is that where there are conditionals (in headers or in non-installed
files) that can just repeat the same or nearly the same logic for each
floating-point type, they should do so, even if in fact the cases for
some types could be unconditionally present or absent because the same
conditionals are true or false for all glibc configurations. This
should make the glibc code with such conditionals easier to read,
because the reader can just see that the same conditionals are
repeated for each type, rather than seeing different conditionals for
different types and needing to reason, at each location with such
differences, why those differences are indeed correct there. (Cases
involving per-format rather than per-type logic are more likely still
to need differences in how they handle different types.)
Having such defines and conditionals also helps in incremental
preparation for adding _Float32 / _Float64 / _Float32x / _Float64x
function aliases. I intend subsequent patches to add such
conditionals corresponding to those already present for _Float128, as
well as making more architecture-specific function implementations use
common macros to define aliases in preparation for adding such _FloatN
/ _FloatNx aliases.
Tested for x86_64.

Avoid build multiarch if compiler warns about mismatched alias
GCC 8 emits an warning for alias for functions with incompatible types
and it is used extensivelly for ifunc resolvers implementations in C
(for instance on weak_alias with the internal symbol name to the
external one or with the libc_hidden_def to set ifunc for internal
usage).
This breaks the build when the ifunc resolver is not defined using
gcc attribute extensions (HAVE_GCC_IFUNC being 0). Although for
all currently architectures that have multiarch support this compiler
options is enabled for default, there is still the option where the
user might try build glibc with a compiler without support for such
extension. In this case this patch just disable the multiarch folder
in sysdeps selections.
GCC 7 and before still builds IFUNCs regardless of compiler support
(although for the lack of attribute support debug information would
be optimal).
Checked with a build on multiarch support architectures (aarch64,
arm, sparc, s390, powerpc, x86_64, i386) with multiarch enable
and disable and with GCC 7 and GCC 8.
* configure.ac (libc_cv_gcc_incompatbile_alias): New define:

posix: Fix improper assert in Linux posix_spawn (BZ#22273)
As noted by Florian Weimer, current Linux posix_spawn implementation
can trigger an assert if the auxiliary process is terminated before
actually setting the err member:
340 /* Child must set args.err to something non-negative - we rely on
341 the parent and child sharing VM. */
342 args.err = -1;
[...]
362 new_pid = CLONE (__spawni_child, STACK (stack, stack_size),
stack_size,
363 CLONE_VM | CLONE_VFORK | SIGCHLD, &args);
364
365 if (new_pid > 0)
366 {
367 ec = args.err;
368 assert (ec >= 0);
Another possible issue is killing the child between setting the err and
actually calling execve. In this case the process will not ran, but
posix_spawn also will not report any error:
269
270 args->err = 0;
271 args->exec (args->file, args->argv, args->envp);
As suggested by Andreas Schwab, this patch removes the faulty assert
and also handles any signal that happens before fork and execve as the
spawn was successful (and thus relaying the handling to the caller to
figure this out). Different than Florian, I can not see why using
atomics to set err would help here, essentially the code runs
sequentially (due CLONE_VFORK) and I think it would not be legal the
compiler evaluate ec without checking for new_pid result (thus there
is no need to compiler barrier).
Summarizing the possible scenarios on posix_spawn execution, we
have:
1. For default case with a success execution, args.err will be 0, pid
will not be collected and it will be reported to caller.
2. For default failure case, args.err will be positive and the it will
be collected by the waitpid. An error will be reported to the
caller.
3. For the unlikely case where the process was terminated and not
collected by a caller signal handler, it will be reported as succeful
execution and not be collected by posix_spawn (since args.err will
be 0). The caller will need to actually handle this case.
4. For the unlikely case where the process was terminated and collected
by caller we have 3 other possible scenarios:
4.1. The auxiliary process was terminated with args.err equal to 0:
it will handled as 1. (so it does not matter if we hit the pid
reuse race since we won't possible collect an unexpected
process).
4.2. The auxiliary process was terminated after execve (due a failure
in calling it) and before setting args.err to -1: it will also
be handle as 1. but with the issue of not be able to report the
caller a possible execve failures.
4.3. The auxiliary process was terminated after args.err is set to -1:
this is the case where it will be possible to hit the pid reuse
case where we will need to collected the auxiliary pid but we
can not be sure if it will be expected one. I think for this
case we need to actually change waitpid to use WNOHANG to avoid
hanging indefinitely on the call and report an error to caller
since we can't differentiate between a default failure as 2.
and a possible pid reuse race issue.
Checked on x86_64-linux-gnu.
* sysdeps/unix/sysv/linux/spawni.c (__spawnix): Handle the case where
the auxiliary process is terminated by a signal before calling _exit
or execve.

x86-64: Use fxsave/xsave/xsavec in _dl_runtime_resolve [BZ #21265]
In _dl_runtime_resolve, use fxsave/xsave/xsavec to preserve all vector,
mask and bound registers. It simplifies _dl_runtime_resolve and supports
different calling conventions. ld.so code size is reduced by more than
1 KB. However, use fxsave/xsave/xsavec takes a little bit more cycles
than saving and restoring vector and bound registers individually.
Latency for _dl_runtime_resolve to lookup the function, foo, from one
shared library plus libc.so:
Before After Change
Westmere (SSE)/fxsave 345 866 151%
IvyBridge (AVX)/xsave 420 643 53%
Haswell (AVX)/xsave 713 1252 75%
Skylake (AVX+MPX)/xsavec 559 719 28%
Skylake (AVX512+MPX)/xsavec 145 272 87%
Ryzen (AVX)/xsavec 280 553 97%
This is the worst case where portion of time spent for saving and
restoring registers is bigger than majority of cases. With smaller
_dl_runtime_resolve code size, overall performance impact is negligible.
On IvyBridge, differences in build and test time of binutils with lazy
binding GCC and binutils are noises. On Westmere, differences in
bootstrap and "makc check" time of GCC 7 with lazy binding GCC and
binutils are also noises.

resolv: Remove bogus targets that build ga_test
Remove the bogus targets (and source) that supposedly build ga_test.
This code was added to resolv very early in the development process
but does not appear to be an actual test program. The target for
building this file is tests but because the glibc Make system is
built the way it is, the target is overriden by higher-level tests
targets and, therefore, the ga_test program is never built. Removing
the target and the source code makes the resolv/Makefile less confusing.

Add MIPS bits/floatn.h.
This patch adds a MIPS-specific bits/floatn.h header. This header is
identical to the ldbl-128 version except for the comment at the top;
the purpose is to ensure that a 32-bit MIPS build installs a header
that is the same as in a 64-bit MIPS build and so properly shows
_Float128 support to be available for 64-bit compilations, on the
general principle of an installation for one multilib providing
headers also suitable for other multilibs.

Install correct bits/long-double.h for MIPS64 (bug 22322).
Similar to bug 21987 for SPARC, MIPS64 wrongly installs the ldbl-128
version of bits/long-double.h, meaning incorrect results when using
headers installed from a 64-bit installation for a 32-bit build. (I
haven't actually seen this cause build failures before its interaction
with bits/floatn.h did so - installed headers wrongly expecting
_Float128 to be available in a 32-bit configuration.)
This patch fixes the bug by moving the MIPS header to
sysdeps/mips/ieee754, which comes before sysdeps/ieee754/ldbl-128 in
the sysdeps directory ordering. (bits/floatn.h will need a similar
fix - duplicating the ldbl-128 version for MIPS will suffice - for
headers from a 32-bit installation to be correct for 64-bit builds.)
Tested with build-many-glibcs.py (compilers build for
mips64-linux-gnu, where there was previously a libstdc++ build failure
as at
<https://sourceware.org/ml/libc-testresults/2017-q4/msg00130.html>).

Add _Float128 function aliases.
This patch adds support for *f128 function aliases on platforms where
long double has the binary128 format (and thus GCC 7 provides the
_Float128 type with the same ABI as long double but as a distinct type
in terms of C type compatibility). This is the same API as provided
in glibc 2.26 for powerpc64le / x86_64 / x86 / ia64 where _Float128
has a different format from long double, with the bulk of the API
coming from TS 18661-3. All the functions alias the corresponding
long double functions, and __* function names are not provided since
those are only needed once for each floating-point format, not more
than once for different types with the same format (so for example,
-ffinite-math-only maps foof128 to __fool_finite, while type-generic
macros end up calling e.g. __issignalingl for _Float128 arguments on
such platforms).
The preparation for this feature was done in previous patches, so this
one just needs to add the relevant makefile and header definitions,
and update macro definitions of libm_alias_ldouble_other_r, to turn on
the feature, and update documentation and ABI baselines.

[AARCH64] Rewrite elf_machine_load_address using _DYNAMIC symbol
This patch rewrites aarch64 elf_machine_load_address to use special _DYNAMIC
symbol instead of _dl_start.
The static address of _DYNAMIC symbol is stored in the first GOT entry.
Here is the change which makes this solution work (part of binutils 2.24):
https://sourceware.org/ml/binutils/2013-06/msg00248.html
i386, x86_64 targets use the same method to do this as well.
The original implementation relies on a trick that R_AARCH64_ABS32
relocation
being resolved at link time and the static address fits in the 32bits.
However, in LP64, normally, the address is defined to be 64 bit.
Here is the C version one which should be portable in all cases.
* sysdeps/aarch64/dl-machine.h (elf_machine_load_address): Use
_DYNAMIC symbol to calculate load address.

84d74e427a771906830800e574a72f8d25a954b8 "powerpc: Cleanup fenv_private.h".
In the powerpc implementation of SET_RESTORE_ROUND, there is the
following code in the "SET" function (slightly simplified):
--
old.fenv = fegetenv_register ();
new.l = (old.l & _FPU_MASK_TRAPS_RN) | r; (1)
if (new.l != old.l) (2)
{
if ((old.l & _FPU_ALL_TRAPS) != 0)
(void) __fe_mask_env ();
fesetenv_register (new.fenv); (3)
--
Line (1) sets the value of "new" to the current value of FPSCR,
but masks off summary bits, exceptions, non-IEEE mode, and
rounding mode, then ORs in the new rounding mode.
Line (2) compares this new value to the current value in order to
avoid setting a new value in the FPSCR (line (3)) unless something
significant has changed (exception enables or rounding mode).
The summary bits are not germane to the comparison, but are cleared
in "new" and preserved in "old", resulting in false negative
comparisons, and unnecessarily setting the FPSCR in those cases
with associated negative performance impacts.
The solution is to treat the summaries identically for "new" and "old":
- save them in SET
- leave them alone otherwise
- restore the saved values in RESTORE
Also minor changes:
- expand _FPU_MASK_RN to 64bit hex, to match other MASKs
- treat bit 52 (left-to-right) as reserved (since it is)
* sysdeps/powerpc/fpu/fenv_private.h (_FPU_MASK_TRAPS_RN):
(_FPU_MASK_FRAC_INEX_RET_CC): Fix masks to more properly handle
summary bits.
(_FPU_MASK_RN): Expand _FPU_MASK_RN to 64bit hex.
(_FPU_MASK_NOT_RN_NI): Treat bit 52 (left-to-right) as reserved.

Use __f128 to define FLT128_* constants in include/float.h for old GCC.
When using compilers before GCC 7, include/float.h provides fallback
definitions of FLT128_* constants. These definitions use 'Q' constant
suffixes, which works for configurations with _Float128 ABI-distinct
from long double, but not where it has the same ABI as long double.
This patch changes the definitions to use the __f128 macro from
<bits/floatn.h>, so allowing them to work in the non-distinct
_Float128 case (where they are used in building glibc tests, not for
building glibc itself) as well.
Tested (a) with build-many-glibcs.py with GCC 6 (installed stripped
shared libraries unchanged by the patch); (b) with
build-many-glibcs.py with GCC 6 together with the main patch to enable
float128 aliases; (c) for x86_64 with both GCC 6 and GCC 7.

Improve malloc initialization sequence
The current malloc initialization is quite convoluted. Instead of
sometimes calling malloc_consolidate from ptmalloc_init, call
malloc_init_state early so that the main_arena is always initialized.
The special initialization can now be removed from malloc_consolidate.
This also fixes BZ #22159.
Check all calls to malloc_consolidate and remove calls that are
redundant initialization after ptmalloc_init, like in int_mallinfo
and __libc_mallopt (but keep the latter as consolidation is required for
set_max_fast). Update comments to improve clarity.
Remove impossible initialization check from _int_malloc, fix assert
in do_check_malloc_state to ensure arena->top != 0. Fix the obvious bugs
in do_check_free_chunk and do_check_remalloced_chunk to enable single
threaded malloc debugging (do_check_malloc_state is not thread safe!).

Use relaxed atomics for malloc have_fastchunks
Currently free typically uses 2 atomic operations per call. The
have_fastchunks
flag indicates whether there are recently freed blocks in the fastbins.
This
is purely an optimization to avoid calling malloc_consolidate too often and
avoiding the overhead of walking all fast bins even if all are empty during
a
sequence of allocations. However using catomic_or to update the flag is
completely unnecessary since it can be changed into a simple boolean and
accessed using relaxed atomics. There is no change in multi-threaded
behaviour
given the flag is already approximate (it may be set when there are no
blocks in
any fast bins, or it may be clear when there are free blocks that could be
consolidated).
Performance of malloc/free improves by 27% on a simple benchmark on AArch64
(both single and multithreaded). The number of load/store exclusive
instructions
is reduced by 33%. Bench-malloc-thread speeds up by ~3% in all cases.

Let signbit use the builtin in C++ mode with gcc < 6.x (bug 22296)
When using gcc < 6.x, signbit does not use the type-generic
__builtin_signbit builtin, instead it uses __MATH_TG.
However, when library support for float128 is available, __MATH_TG uses
__builtin_types_compatible_p, which is not available in C++ mode.
On the other hand, libstdc++ undefines (in cmath) many macros from
math.h, including signbit, so that it can provide its own functions.
However, during its configure tests, libstdc++ just tests for the
availability of the macros (it does not undefine them, nor does it
provide its own functions).
Finally, libstdc++ configure tests include math.h and get the definition
of signbit that uses __MATH_TG (and __builtin_types_compatible_p).
Since libstdc++ does not undefine the macros during its configure
tests, they fail.
This patch lets signbit use the builtin in C++ mode when gcc < 6.x is
used. This allows the configure test in libstdc++ to work.
Tested for x86_64.

Move some float128 symbol version definitions.
With support for _Float128 functions on platforms where that type has
the same ABI as long double, as well as on platforms where it is
ABI-distinct, those functions will need to be exported from glibc's
shared libraries at appropriate symbol versions in each case.
This patch avoids duplication of lists of symbols to export by moving
the symbols other than __* to math/Versions and stdlib/Versions.
There, they are conditional on <float128-abi.h> defining
FLOAT128_VERSION and a default version of that header is added that
does not define that macro. Enabling the float128 function aliases
will then include adding a sysdeps/ieee754/ldbl-128/float128-abi.h
that defines FLOAT128_VERSION to GLIBC_2.27. Symbols __* remain in
sysdeps/ieee754/float128/Versions; those symbols should be present
only once per floating-point format, not once per type.
Note that if any platforms currently lacking support for a type with
binary128 format get glibc support for such a type in future (whether
only as _Float128, or also as a new long double format), and new libm
functions (present for all types) have been added by then, additional
macros will be needed to allow such functions to get a version of the
form "GLIBC_2.28 if the platform had _Float128 support by then, or the
later version at which that platform had _Float128 support added".
This is not however a preexisting condition, but would have applied
equally to the existing support for _Float128 as an ABI-distinct
type. New all-type libm functions should just be added to the
appropriate symbol version (currently GLIBC_2.27) for all types, with
such special-case handling for _Float128 versions (and _Float64x as
well in future) waiting until someone actually wants to add support
for _Float128 to an existing platform after a release in which that
platform and a post-2.26 libm function had support but that platform
lacked _Float128 support.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by this patch. Also tested in conjunction
with the remaining changes to enable float128 aliases.

result, the link editor does not export a definition of
__malloc_initialize_hook from the main program, so that it no longer
interposes the variable definition in libc.so. Specifying the symbol
version restores the exported symbol.

locale: No warning for non-symbolic character (bug 22295)
In "Is it OK to write ASCII strings directly into locale source files?"
https://sourceware.org/ml/libc-alpha/2017-07/msg00807.html there is
universal consensus that we do not have to keep writing <Uxxxx> symbolic
characters in locale files.
Ulrich Drepper's historical comment was that symbolic characters were
used for the eventuality of converting the source files to any encoding
system. Fast forward to today and UTF-8 is the standard. So the
requirement of <Uxxxx> is hard to justify.
Zack Weinberg's excellent scripts are coming along we can use these to
find instances of human errors in the scripts:
https://sourceware.org/ml/libc-alpha/2017-07/msg00860.html
https://sourceware.org/ml/libc-alpha/2017-08/msg00136.html
It still won't be easy to distinguish from i for Ã, but that's still the
case for <Uxxxx> characters which humans can't read either.
Since we all agreed that we should be able to use non-symbolic (<Uxxxx>)
characters in locale files, the following change removes the verbose
warning that is raised if you use non-symbolic characters in the locale
file.

invalid.

locale: Fix localedef exit code (Bug 22292)
The error and warning handling in localedef, locale, and iconv
is a bit of a mess.
We use ugly constructs like this:
WITH_CUR_LOCALE (error (1, errno, gettext ("\
cannot read character map directory `%s'"), directory));
to issue errors, and read error_message_count directly from the
error API to detect errors. The problem with that is that the
code also uses error to print warnings, and informative messages.
All of this leads to problems where just having warnings will
produce an exit status as-if errors had been seen.
To fix this situation I have adopted the following high-level
changes:
* All errors are counted distinctly.
* All warnings are counted distinctly.
* All informative messages are not counted.
* Increasing verbosity cannot generate *more* errors, and
it previously did for errors conditional on verbose,
this is now fixed.
* Increasing verbosity *can* generate *more* warnings.
* Making the output quiet cannot generate *fewer* errors,
and it previously did for errors conditional on be_quiet,
this is now fixed.
* Each of error, warning, and informative message has it's
own function to call defined in record-status.h, and they
are: record_error, record_warning, and record_verbose.
* The record_error function always records an error, but
conditional on be_quiet may not print it.
* The record_warning function always records a warning,
but conditional on be_quiet may not print it.
* The record_verbose function only prints the verbose
message if verbose is true and be_quiet is false.
This has allowed the following fix:
* Previously any warnings were being treated as errors
because they incremented error_message_count, but now
we properly return an exit status of 1 if there are
warnings but output was generated.
All of this allows localedef to correctly decide if errors,
or warnings were present, and produce the correct exit code.
The locale and iconv programs now also use record-status.h
and we have removed the WITH_CUR_LOCALE hack, and instead
have internal push_locale/pop_locale functions centralized
in the record routines.

localedata: Reorganize Unicode LC_CTYPE inclusion.
The commit does the following things:
* Move non-transliteration Unicode generated data to i18n_ctype.
* Copy the i18n_ctype data into i18n and add transliteration.
In the future, any locale which needs Unicode LC_CTYPE data can
also just use `copy i18n_ctype` and get the base character classes
and maps without transliteration.
Tested by compiling all the locales and my prototype C.UTF-8 which
uses it.

Fix TLS relocations against local symbols on powerpc32, sparc32 and sparc64
Normally, TLS relocations against local symbols are optimised by the linker
to be absolute. However, gold does not do this, and so it is possible to
end up with, for example, R_SPARC_TLS_DTPMOD64 referring to a local symbol.
Since sym_map is left as null in elf_machine_rela for the special local
symbol case, the relocation handling thinks it has nothing to do, and so
the module gets left as 0. Havoc then ensues when the variable in question
is accessed.
Before this fix, the main_local_gold program would receive a SIGBUS on
sparc64, and SIGSEGV on powerpc32. With this fix applied, that test now
passes like the rest of them.
* sysdeps/powerpc/powerpc32/dl-machine.h (elf_machine_rela):
Assign sym_map to be map for local symbols, as TLS relocations
use sym_map to determine whether the symbol is defined and to

Run libm long double tests for long double = double.
All interfaces in the glibc API ought to be covered by the testsuite,
even where they alias other interfaces. This patch arranges for libm
tests to be run for long double when it aliases double; previously
those tests were run only for the floating-point types with distinct
formats. The long double tests are made to use the double ulps values
in this case, as having a separate duplicate set of ulps for them
seems unnecessary; to accommodate that, the test-<type>.h headers now
specify the macro indexing into the ulps array explicitly instead of
having it computed from PREFIX.
Nothing special is done about vector function tests. None are
supported for any long double = double platforms, and supporting
vector functions for a type alias such as _Float32 would not simply
fall out of adding the scalar aliases for that type - it would require
vector function wrappers like those for *_finite (or, better, a new
GCC feature to allow specifying the asm name for vector functions
independently of that for scalar ones, as previously discussed), so it
seems reasonable to require the sysdeps makefile setting of
libmvec-tests to be updated if any such tests are to be run for type
aliases.

Linux: Consolidate {RTLD_}SINGLE_THREAD_P definition
Current GLIBC has two ways to implement the single thread optimization
on syscalls to avoid calling the cancellation path: either by using
global variables (__{libc,pthread}_multiple_thread) or by accessing
the TCB field (defined by TLS_MULTIPLE_THREADS_IN_TCB). Both the
variables and the macros to acces its value are defined in the
architecture sysdep-cancel.h header.
This patch consolidates its definition on only one header,
sysdeps/unix/sysv/linux/sysdep-cancel.h, and adds a new define
(SINGLE_THREAD_BY_GLOBAL) which the architecture defines if it prefer
to use the global variables instead of the TCB field. This is an
optimization, so if the architecture does not define it, the TCB
method will be used as default.

Use generic alias macros in ldbl-opt.
This patch fixes ldbl-opt code to use generic libm alias macros in
preparation for getting _FloatN / _FloatNx aliases where appropriate.
Four functions are affected, that undefine and redefine alias macros
before including the implementations they wrap in such a way that
_FloatN / _FloatNx aliases would not appear. s_clog10l.c undefines
and redefined declare_mgen_alias, so just needs a
libm_alias_ldouble_other call added. w_exp10l_compat.c undefines and
redefines weak_alias, but in fact does not need to do so, since
math/w_exp10l_compat.c uses libm_alias_ldouble and does not use
weak_alias other than through that, so the undefines and redefines of
weak_alias are removed. w_lgamma_compatl.c and w_remainderl_compat.c
are made to use libm_alias_ldouble_other in conjunction with restoring
the original definition of weak_alias so this is effective.
Tested with build-many-glibcs.py. Installed stripped shared libraries

Add libm_alias_*_other_r macros.
Some libm functions are unable to use the generic alias macros such as
libm_alias_double because they have special symbol versioning
requirements for the main float, double or long double public names.
To facilitate adding _FloatN / _FloatNx function aliases in future,
it's still desirable to have generic macros those functions can use as
far as possible. This patch adds macros such as
libm_alias_double_other, which only define names for _FloatN /
_FloatNx aliases, not for float / double / long double. As present,
all these new macros do nothing, but they are called in the
appropriate places in macros such as libm_alias_double. This patch
also arranges for lgamma implementations, and the recently added
optimized float function implementations, to use the new macros to
make them ready for addition of _FloatN / _FloatNx aliases.
Tested for x86_64, and tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by this patch.

Use generic macros for lgamma_r function aliases.
Continuing the use of generic macros for defining libm function
aliases, in preparation for adding more _FloatN / _FloatNx function
names, this patch makes the lgamma_r functions use such macros.
declare_mgen_alias_r becomes a standard macro in math-type-macros.h
instead of being locally defined in w_lgamma_r_templace.c. This in
turn must be defined by each math-type-macros-<type>.h. Rather than
providing an unused default in math-type-macros.h, that header is made
to give an error if math-type-macros-<type>.h failed to define
declare_mgen_alias or declare_mgen_alias_r. The compat lgamma_r
wrappers are updated similarly. The ldbl-opt versions are removed as
no longer needed.
Tested for x86_64, and with build-many-glibcs.py. Installed stripped
shared libraries are unchanged except for powerpc64le (where the usual
issue applies that an ldbl-opt long double function previously used
long_double_symbol unconditionally and now the symbol versions on
powerpc64le mean weak_alias is used instead, resulting in the same
symbol versions in the final shared library but still enough
difference in the input objects for that library not to be
byte-identical).

Ensure C99 and C11 interfaces are available for C++ [BZ #21326]
This patch ensures that the C99 and C11 features required by C++ are
defined according to the value of the __cplusplus macro, and not just
because G++ always defines _GNU_SOURCE. This will allow G++ to stop
defining _GNU_SOURCE some day, without causing the C99 and C11
interfaces to disappear for C++ programs.

openpty: use TIOCGPTPEER to open slave side fd
Newer kernels expose the ioctl TIOCGPTPEER [1] call to userspace which
allows to
safely allocate a file descriptor for a pty slave based solely on the master
file descriptor. This allows us to avoid path-based operations and makes
this
function a lot safer in the face of devpts mounts in different mount
namespaces.

Use libm_alias_ldouble for ldbl-128 functions.
This patch makes ldbl-128 functions use libm_alias_ldouble to define
function aliases. float128_private.h is updated accordingly. Most of
the ldbl-64-128 wrappers are removed as no longer needed with this
change (leaving those that involve versioning for functions in libc or
that shouldn't be exported from libm for _Float128 / _Float64x types
with the same format as long double).

stripped shared libraries are unchanged by this patch.

malloc: Fix tcache leak after thread destruction [BZ #22111]
The malloc tcache added in 2.26 will leak all of the elements remaining
in the cache and the cache structure itself when a thread exits. The
defect is that we do not set tcache_shutting_down early enough, and the
thread simply recreates the tcache and places the elements back onto a
new tcache which is subsequently lost as the thread exits (unfreed
memory). The fix is relatively simple, move the setting of
tcache_shutting_down earlier in tcache_thread_freeres. We add a test
case which uses mallinfo and some heuristics to look for unaccounted for
memory usage between the start and end of a thread start/join loop. It
is very reliable at detecting that there is a leak given the number of
iterations. Without the fix the test will consume 122MiB of leaked
memory.

Remove redundant ldbl-64-128 files.
Various source files in ldbl-64-128 are redundant, because they wrap
files that no longer provide public symbols that need special
versioning (those symbols having moved to separate errno-setting
wrappers), or, in the case of w_scalblnl.c, because the type-generic
template now does everything required (it deals with symbol versioning
for use in libm, and this file is never built for libc anyway - the
compat scalbln* symbols in libc, as opposed to scalbn*, are only for
i386 and m68k and are aliases to the corresponding scalbn* symbols).
This patch removes those redundant files.
Tested with build-many-glibcs.py (for all ldbl-64-128 configurations)
that installed stripped shared libraries are unchanged by this patch.

aarch64: Optimized implementation of memmove for Qualcomm Falkor
This is an optimized memmove implementation for the Qualcomm Falkor
processor core. Due to the way the falkor memcpy needs to be written,
code cannot be easily shared between memmove and memcpy like in case
of other aarch64 memcpy implementations due to which this routine is
separate. The underlying principle is the same as that of memcpy
where it tries to use registers with the same lower 4 bits for
fetching the same stream, thus optimizing hardware prefetcher
performance.
The memcpy copy loop copies 64 bytes at a time using the same register
pair since that's the way to train the hardware prefetcher on the
falkor core. memmove cannot quite do that since it needs to avoid
overlaps, so it does the next best thing, i.e. has a 32 byte loop with
a 32 byte end (prefetch a loop ahead to account for overlapping
locations) with register pairs that alias so that they hit the same
prefetcher. Due to this difference in loop size, they have to
currently be separate implementations but efforts are on to try and
get memmove to fall back into memcpy whenever it can without simply
duplicating all of the code.
Performance:
The routine fares around 20-25% better than the generic memmove for
most medium to large sizes (i.e. > 128 bytes) for the new walking
memmove benchmark (memmove-walk) with an unexplained regression
between 1K and 2K. The minor regression is something worth looking
into for us, but the remaining gains are significant enough that we
would like this included upstream as we looking into the cause for the
regression. Here is a snippet of the numbers as generated from the
microbenchmark by the compare_strings script. Comparisons are against

benchtests: Memory walking benchmark for memmove
This benchmark is an attempt to eliminate cache effects from string
benchmarks. The benchmark walks both ways through a large memory area
and copies different sizes of memory and alignments one at a time
instead of looping around in the same memory area. This is a good
metric to have alongside the simple memmove benchmark (which is only
really useful for smaller sizes) especially for larger sizes where the
likelihood of the call being done only once is pretty high.
This benchmark is different from memcpy in that it also tests
overlapping copies.

Remove add-ons mechanism.
glibc has an add-ons mechanism to allow additional software to be
integrated into the glibc build. Such add-ons may be within the glibc
source tree, or outside it at a path passed to the --enable-add-ons
configure option.
localedata and crypt were once add-ons, distributed in separate
release tarballs, but long since stopped using that mechanism.
Linuxthreads was always an add-on. Ports spent some time as an add-on
with separate release tarballs, then was first moved into the glibc
source tree, then had its sysdeps files moved into the main sysdeps
hierarchy so the add-ons mechanism was no longer used. NPTL spent
some time as an add-on in the main glibc tree before stopping using
the add-on mechanism. libidn used to have separate release tarballs
but no longer does so, but still uses the add-ons mechanism within the
glibc source tree. Various other software has supported building with
the add-ons mechanism at times in the past, but I don't think any is
still widely used.
Add-ons involve significant, little-used complexity in the glibc build
system, and make it hard to understand what the space of possible
glibc configurations is. This patch removes the add-ons mechanism.
libidn is now built via the Subdirs mechanism to cause any
configuration using sysdeps/unix/inet to build libidn; HAVE_LIBIDN
(which effectively means shared libraries are available) is now
defined via sysdeps/unix/inet/configure. Various references to
add-ons around the source tree are removed (in the case of maint.texi,
the example list of sysdeps directories is still very out of date).
Externally maintained ports should now put their files in the normal
sysdeps directory structure rather than being arranged as add-ons;
they probably need to change e.g. elf.h anyway, rather than actually
being able to work just as a drop-in subtree. Hurd libpthread should
be arranged similarly to NPTL, so some files might go in a
hurd-pthreads (or similar) top-level directory in glibc, while sysdeps
files should go in the normal sysdeps directory structure (possibly in
hurd or hurd-pthreads subdirectories, just as there are nptl
subdirectories in the sysdeps tree).

Use libm_alias_double for dbl-64 fma.
This patch makes dbl-64 fma use libm_alias_double. The ldbl-opt
version is removed. The sparc32 version no longer needs to handle
compat symbols, while alpha needs a new wrapper to avoid getting the
ldbl-128 version (where ldbl-opt is earlier in the list of sysdeps
directories, so previously fma came from there).
Tested for x86_64, and tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by the patch.

Restore sparc32 copysignl, fabsl, fmal compat symbols (bug 22229).
32-bit SPARC libm should have compat symbols for copysignl
(GLIBC_2.0), fabsl (GLIBC_2.0), fmal (GLIBC_2.1), pointing to the
double functions; they were present in glibc 2.8, for example, but are
now missing, probably when optimized SPARC function implementations
were added without appropriate compat symbol handling. The same
applies to copysignl in libc. This patch restores those compat
symbols.
Tested with build-many-glibcs.py for sparcv9-linux-gnu.

Remove alpha nearbyint wrapper.
Given my recent changes, sysdeps/alpha/fpu/s_nearbyint.c is no longer
needed: it just includes the dbl-64/wordsize-64 version, which is the
one that would be used anyway, and defines a compat symbol,
duplicating the same compat symbol defined by the dbl-64/wordsize-64
version through use of libm_alias_double. Thus, this patch removes
the redundant wrapper.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for alpha.

Use libm_alias_double for dbl-64 modf.
This patch makes dbl-64 modf use libm_alias_double. Both the dbl-64

Add C++ versions of iscanonical for ldbl-96 and ldbl-128ibm (bug 22235)
All representations of floating-point numbers in types with IEC 60559
binary exchange format are canonical. On the other hand, types with IEC
60559 extended formats, such as those implemented under ldbl-96 and
ldbl-128ibm, contain representations that are not canonical.
TS 18661-1 introduced the type-generic macro iscanonical, which returns
whether a floating-point value is canonical or not. In Glibc, this
type-generic macro is implemented using the macro __MATH_TG, which, when
support for float128 is enabled, relies on __builtin_types_compatible_p
to select between floating-point types. However, this use of
iscanonical breaks C++ applications, because the builtin is only
available in C mode.
This patch provides a C++ implementation of iscanonical that relies on
function overloading, rather than builtins, to select between
floating-point types.
Unlike the C++ implementations for iszero and issignaling, this
implementation ignores __NO_LONG_DOUBLE_MATH. The double type always
matches IEC 60559 double format, which is always canonical. Thus, when
double and long double are the same (__NO_LONG_DOUBLE_MATH), iscanonical
always returns 1 and is not implemented with __MATH_TG.
Tested for powerpc64, powerpc64le and x86_64.

Use libm_alias_double for more dbl-64 functions.
This patch makes more dbl-64 functions use libm_alias_double to define
function aliases. Specifically, it makes the change for functions
with dbl-64/wordsize-64 versions, changing both the dbl-64 and
dbl-64/wordsize-64 versions and removing the ldbl-opt wrappers.
Functions are excluded from this patch if there are complications
because of versions of those functions also present in libc, or
architecture-specific wrappers round these files.
Tested for x86_64, and with build-many-glibcs.py. Installed stripped
shared libraries are unchanged except for alpha (where increased use
of dbl-64/wordsize-64 files, where previously ldbl-opt files that

Introduce NO_RTLD_HIDDEN, make hurd use it instead of NO_HIDDEN
On the Hurd, the rtld needs to see its own dumb versions of a few functions
(defined in sysdeps/mach/hurd/dl-sysdep.c) overridden by libc's versions
once
loaded. rtld should thus not have hidden attribute for these. To achieve
this,
the Hurd port used to just define NO_HIDDEN, which disables it completely.
For
now, this changes that to disabling it for all rtld functions, for
simplicity.

Use libm_alias_double for dbl-64 atan, tan.
This patch makes the dbl-64 atan and tan implementations use
libm_alias_double, removing the corresponding ldbl-opt wrappers.
Tested for x86_64, and with build-many-glibcs.py. Installed stripped
shared libraries are unchanged on non-ldbl-opt platforms. For
ldbl-opt configurations, the patch has the effect of causing
compat_symbol to define atanl and tanl in terms of __atan and __tan
instead of in terms of atan and tan, which is enough to change the
installed stripped libm.so.

Make dbl-64 atan and tan into weak aliases.
This patch converts the dbl-64 implementations of atan and tan into
weak aliases of __atan and __tan, in preparation for making them use
libm_alias_double. Consequent changes are made to the x86_64
multiarch versions wrapping round them (with the dbl-64 functions,
like other such functions, being made not to define their aliases at
all if __atan or __tan are defined as macros by an including file).
Tested for x86_64, and with build-many-glibcs.py.

powerpc: Optimize memrchr for power8
Vectorized loops are used for sizes greater than 32B to improve
performance over power7 optimization. This shows as an average
of 25% improvement depending on the position of search

Use libm_alias_double for some dbl-64 functions.
Continuing the move of libm aliases to common macros that can create
_FloatN / _FloatNx aliases in future, this patch converts some dbl-64
functions to using libm_alias_double, thereby eliminating the need for
some ldbl-opt wrappers.
This patch deliberately limits what functions are converted so that it
can be verified by comparison of stipped binaries. Specifically, atan
and tan are excluded because they first need converting to being weak
aliases; fma is omitted as it has additional complications with
versions in other directories (removing the ldbl-opt version can
e.g. cause the ldbl-128 version to be used instead of dbl-64); and
functions that have both dbl-64/wordsize-64 and ldbl-opt versions are
excluded because ldbl-opt currently always wraps dbl-64 function
versions, so changing those will result in platforms using both
ldbl-opt and dbl-64/wordsize-64 (i.e. alpha) starting to use the
dbl-64/wordsize-64 versions of those functions (which is good, as an
optimization, but still best separated from the present patch to get
better validation).
Tested for x86_64, and tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by the patch.

new worst-case error: 0.82 ulp

powf(x,y) is implemented as exp2(y*log2(x)) with the same algorithms
that are used in exp2f and log2f, except that the log2f polynomial is
larger for extra precision and its output (and exp2f input) may be
scaled by a power of 2 (POWF_SCALE) to simplify the argument reduction
step of exp2 (possible when efficient round and convert toint operation
is available).
The special case handling tries to minimize the checks in the hot path.
When the input of exp2_inline is checked, int arithmetics is used as
that was faster on the tested aarch64 cores.

New generic logf
without wrapper on aarch64:
logf reciprocal-throughput: 2.2x faster
logf latency: 1.9x faster
old worst case error: 0.89 ulp
new worst case error: 0.82 ulp
aarch64 .text size: -356 bytes
aarch64 .rodata size: +240 bytes
Uses double precision arithmetics and a lookup table to allow smaller
polynomial and avoid the use of division.
Data is in a separate translation unit with fixed layout to prevent the
compiler generating suboptimal literal access.
Errors are handled inline according to POSIX rules, but this patch
keeps the wrapper with SVID compatible error handling.
Needs libm-test-ulps adjustment for clogf in non-nearest rounding mode.

Simplify C99 isgreater macros
Simplify the C99 isgreater macros. Although some support was added
in GCC 2.97, not all targets added support until GCC 3.1. Therefore
only use the builtins in math.h from GCC 3.1 onwards, and defer to
generic macros otherwise. Improve the generic isunordered macro
to use compares rather than call fpclassify twice - this is not only
faster but also correct for signaling NaNs.

Fix nearbyint arithmetic moved before feholdexcept (bug 22225).
In <https://sourceware.org/ml/libc-alpha/2013-05/msg00722.html> I
remarked on the possibility of arithmetic in various nearbyint
implementations being scheduled before feholdexcept calls, resulting
in spurious "inexact" exceptions.
I'm now actually observing this occurring in glibc built for ARM with
GCC 7 (in fact, both copies of the same addition/subtraction sequence
being combined and moved out before the conditionals and
feholdexcept/fesetenv pairs), resulting in test failures.
This patch makes the nearbyint implementations with this particular
feholdexcept / arithmetic / fesetenv pattern consistently use
math_opt_barrier on the function argument when first used in
arithmetic, and also consistently use math_force_eval before fesetenv
(the latter was generally already done, but the dbl-64/wordsize-64
implementation used math_opt_barrier instead, and as
math_opt_barrier's intended effect is through its output value being
used, such a use that doesn't use the return value is suspect).
Tested for x86_64 (--disable-multi-arch so more of these
implementations get used), and for ARM in a configuration where I saw
the problem scheduling.
[BZ #22225]
* sysdeps/ieee754/dbl-64/s_nearbyint.c (__nearbyint): Use
math_opt_barrier on argument when doing arithmetic on it.

Fix make-syscalls.sh VDSO support for GCC 8.
sysdeps/unix/make-syscalls.sh has support, used only by x32, for
generating IFUNCs for kernel VDSO symbols. This support creates
IFUNCs by setting symbol types manually, which is bad for debug info
and does not work with current GCC mainline because it results in
errors from the checks on types of function aliases.
This patch fixes it to use the common __ifunc macro, which uses the
ifunc attribute when available and so works with GCC mainline. Note
however that the original error resulted from an indirect inclusion of
a header declaring __gettimeofday from the generated sources, and
using __ifunc now relies on such an indirect inclusion remaining as it
means use of __typeof to determine the correct types. If glibc's
headers change in such a way as to remove that indirect inclusion, it
will become necessary to change the syscalls.list syntax for VDSO
syscalls so the name of the header to include can be specified.
Tested (compilation only) with build-many-glibcs.py that this fixes
the build for x32 with GCC mainline.
* sysdeps/unix/make-syscalls.sh: Use __ifunc to define symbols
using VDSO.

Fix range check in do_tunable_update_val
Current implementation of tunables does not set arena_max and arena_test
values. Any value provided by glibc.malloc.arena_max and
glibc.malloc.arena_test parameters is ignored.
These tunables have minval value set to 1 (see elf/dl-tunables.list file)
and undefined maxval value. In that case default value (which is 0. see
scripts/gen-tunables.awk) is being used to set maxval.
For instance, generated tunable_list[] entry for arena_max is:
(gdb) p *cur
$1 = {name = 0x7ffff7df6217 "glibc.malloc.arena_max",
type = {type_code = TUNABLE_TYPE_SIZE_T, min = 1, max = 0},
val = {numval = 0, strval = 0x0}, initialized = false,
security_level = TUNABLE_SECLEVEL_SXID_IGNORE,
env_alias = 0x7ffff7df622e "MALLOC_ARENA_MAX"}
As a result, any value of glibc.malloc.arena_max is ignored by
TUNABLE_SET_VAL_IF_VALID_RANGE macro
__type min = (__cur)->type.min; <- initialized to 1
__type max = (__cur)->type.max; <- initialized to 0!
if (min == max) <- false
{
min = __default_min;
max = __default_max;
}
if ((__type) (__val) >= min && (__type) (val) <= max) <- false
{
(__cur)->val.numval = val;
(__cur)->initialized = true;
}
Assigning correct min/max values at a build time fixes a problem.
Plus, a bit of optimization: Setting of default min/max values for the
given type at a run time might be eliminated.
* elf/dl-tunables.c (do_tunable_update_val): Range checking fix.
* scripts/gen-tunables.awk: Set unspecified minval and/or maxval
values to correct default value for given type.

Skip PT_DYNAMIC segment with p_filesz == 0 [BZ #22101]
ELF objects generated with "objcopy --only-keep-debug" have
Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
DYNAMIC 0x0+e28 0x0+200e40 0x0+200e40 0x0+ 0x0+1a0 RW 0x8
with 0 file size. ld.so should skip such PT_DYNAMIC segments.
Without a PT_DYNAMIC segment the loading of the shared object will
fail, and therefore ldd on such objects will also fail instead of
crashing. This provides better diagnostics for tooling that is
attempting to inspect the invalid shared objects which may just
contain debug information.

Use generic __ifunc for SPARC.
glibc fails to build with GCC mainline for SPARC because of the use of
manually-created IFUNCs, which fail the tests of compatibility of
function alias types. This patch changes sparc-ifunc.h to use the
generic __ifunc in defining sparc_libm_ifunc. The generic __ifunc can
use the GCC ifunc attribute when available, so ensuring
type-correctness as well as better debug info than when setting symbol
types in asm statements.
Note that for this to fix the build with GCC mainline the GCC patch
<https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01779.html>, or
building GCC with --enable-gnu-indirect-function, is also needed.

Fix ia64 executable stack default (bug 22156).
As per https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01220.html ia64
defaults to non-executable stacks in the Linux kernel (furthermore,
the use of function descriptors means that trampolines for nested
function pointers never need an executable stack). glibc however
defines DEFAULT_STACK_PERMS to include PF_X for that architecture,
meaning (a) elf/check-execstack fails and (b) (from code inspection,
not tested, but this is why I think this is a user-visible bug) thread
stacks are unnecessarily mapped with execute permission. This patch
fixes the DEFAULT_STACK_PERMS definition in question.

posix: Add compat glob symbol to not follow dangling symbols
This patch follows commit 5554304f0 (posix: Allow glob to match dangling
symlinks [BZ #866]) by adding a compat symbol that follow previous
semantic of not following dangling symlinks and thus avoiding call
gl_lstat with GLOB_ALTDIRFUNC.
It avoids failure with old binaries that not set the alternate function
pointer for lstat (GNUmake for instance). The following scenario, for
instance, fails with current GNUmake because glibc will access unitialized
memory when calling gl_lstat:
$ cat src/t/t.c
int main ()
{
return 0;
}
$ cat Makefile
SRC = $(wildcard src/*/t.c)
OBJ = $(patsubst src/%.c, obj/%.o, $(SRC))
prog: $(OBJ)
$(CC) $(CFLAGS) $(LDFLAGS) $(LIBS) $(OBJ) -o prog
obj/%.o: src/%.c
$(CC) $(CFLAGS) -c $< -o $@
$ make
This works as expected with the patch applied. Since it is for generic
ABI, default compat symbols are added with override for Linux due LFS.
Now we have two compat symbols for glob on Linux:
1. sysdeps/unix/sysv/linux/oldglob.c which implements glob64 with
the old dirent layout. For this implementation I also set it to
not follow dangling symlinks (which is the safest path).
2. sysdeps/unix/sysv/linux/glob{64}-lstat-compat.c which implements
the compat symbol for dangling symlinks. As for generic glob,
the implementation uses XSTAT_IS_XSTAT64 to define whether
both __glob_lstat_compat and __glob64_lstat_compat should be
different implementations. For archictures that define
XSTAT_IS_XSTAT64, __glob_lstat_compat is aliased to
__glob64_lstat_compat.
3. sysdeps/unix/sysv/linux/alpha/oldglob.c with a different glob_t
layout. As for 1. this patch changes it to not follow dangling
symlinks.
The patch also bumps _GNU_GLOB_INTERFACE_VERSION to 2 to advertise the
new semantic. On GNUmake, for instance, it will force to it use its
internal glob implementation instead and avoiding triggering the same
failure on builds against newer GLIBCs.
Checked on x86_64-linux-gnu and i686-linux-gnu. I also checked
with a build against the major ABIs required to check for the abilist.
The changes should also work on gnulib (I run gnulib-tool.py check glob
and it shown no regressions).

New expf and exp2f version without SVID compat wrapper
This patch changes the expf and exp2f error handling semantics to only
set errno accoring to POSIX rules. New symbol version is introduced at
GLIBC_2.27.

Internal calls to __expf now get the new error semantics, this seems to
only affect sysdeps/i386/fpu/s_expm1f.S where the errno-only behaviour
should be correct.

Optimized generic expf and exp2f with wrappers
Based on new expf and exp2f code from
https://github.com/ARM-software/optimized-routines/
with wrapper on aarch64:
expf reciprocal-throughput: 2.3x faster
expf latency: 1.7x faster
without wrapper on aarch64:
expf reciprocal-throughput: 3.3x faster
expf latency: 1.7x faster
without wrapper on aarch64:
exp2f reciprocal-throughput: 2.8x faster
exp2f latency: 1.3x faster
libm.so size on aarch64:
.text size: -152 bytes
.rodata size: -1740 bytes
expf/exp2f worst case nearest rounding error: 0.502 ulp
worst case non-nearest rounding error: 1 ulp
Error checks are inline and errno setting is in separate tail called
functions, but the wrappers are kept in this patch to handle the
_LIB_VERSION==_SVID_ case. (So e.g. errno is set twice for expf calls
and once for __expf_finite calls on targets where the new code is used.)
Double precision arithmetics is used which is expected to be faster on
most targets (including soft-float) than using single precision and it
is easier to get good precision result with it.
Const data is kept in a separate translation unit which complicates
maintenance a bit, but is expected to give good code for literal loads
on most targets and allows sharing data across expf, exp2f and powf.
(This data is disabled on i386, m68k and ia64 which have their own
expf, exp2f and powf code.)
Some details may need target specific tweaks:
- best convert and round to int operation in the arg reduction may be
different across targets.
- code was optimized on fma target, optimal polynomial eval may be
different without fma.
- gcc does not always generate good code for fp bit representation
access via unions or it may be inherently slow on some targets.
The libm-test-ulps will need adjustment because..
- The argument reduction ideally uses nearest rounded rint, but that is
not efficient on most targets, so the polynomial can get evaluated on a
wider interval in non-nearest rounding mode making 1 ulp errors common
in that case.
- The polynomial is evaluated such that it may have 1 ulp error on
negative tiny inputs with upward rounding.

Let fpclassify use the builtin when optimizing for size in C++ mode (bug
22146)
When optimization for size is on (-Os), fpclassify does not use the
type-generic __builtin_fpclassify builtin, instead it uses __MATH_TG.
However, when library support for float128 is available, __MATH_TG uses
__builtin_types_compatible_p, which is not available in C++ mode.
On the other hand, libstdc++ undefines (in cmath) many macros from
math.h, including fpclassify, so that it can provide its own functions.
However, during its configure tests, libstdc++ just tests for the
availability of the macros (it does not undefine them, nor does it
provide its own functions).
Finally, when libstdc++ is configured with optimization for size
enabled, its configure tests include math.h and get the definition of
fpclassify that uses __MATH_TG (and __builtin_types_compatible_p).
Since libstdc++ does not undefine the macros during its configure tests,
they fail.
This patch lets fpclassify use the builtin in C++ mode, even when
optimization for size is on. This allows the configure test in
libstdc++ to work.
Tested for powerpc64le and x86_64.

This patch removes the Banner mechanism, with the last remaining
Banner file replaced by a contrib.texi entry. This accords with the
principle that the output of running libc.so.6 is not the place to
credit particular contributions (the manual is), and with all other
configuration options not mentioned there, it doesn't seem appropriate
to focus there on the one question of whether the one remaining piece
configured as an add-on was enabled or not.

Remove conditional on LDBL_MANT_DIG from e_lgammal_r.c
The IEEE 754 implementation of lgammal in sysdeps/ieee754/ldbl-128/ used
to be shared by IBM's implementation in sysdeps/ieee754/ldbl-128ibm/ (by
an inclusion of the source file). In order for the algorithm to work
for IBM's implementation, a check for LDBL_MANT_DIG was required. Since
the source file is no longer shared, the requirement for the check is
gone. This patch removes the conditionals.

ldbl-128ibm: Automatic replacing of _Float128 and L()
The ldbl-128ibm implementation of j0l, j1l, lgammal_r, and cbrtl, as
well as the tables used by expl were copied from ldbl-128. However, the
original files used _Float128 for the type and L() for the literal
suffix. This patch uses the following sed command to rewrite _Float128
as long double and L(x) as xL (for e_expl.c, e_j0l.c, e_j1l.c,
e_lgammal_r.c, and t_expl.h):
sed -i <filename> \
-e "/^#define _Float128 long double/d" \
-e "/^#define L(x) x ## L/d" \
-e "/L(/s/)/L/" \
-e "/L(/s/L(//" \
-e "s/_Float128/long double/g"
For sysdeps/ieee754/ldbl-128ibm/s_cbrtl.c, this sed command incorrectly
replaces a few occurrences of L(), so the following command is used
instead:
sed -i sysdeps/ieee754/ldbl-128ibm/s_cbrtl.c \
-e "/^#define _Float128 long double/d" \
-e "/^#define L(x) x ## L/d" \
-e "s/L(0\.3\{40\})/0.3333333333333333333333333333333333333333L/" \
-e "s/L(3\.7568280825958912391243e-1)/3.7568280825958912391243e-1L/" \
-e "/L(/s/)/L/" \
-e "/L(/s/L(//" \
-e "s/_Float128/long double/g"

ldbl-128ibm: Copy implementations from ldbl-128 instead of including them
Some files under sysdeps/ieee754/ldbl-128ibm/ are able to reuse the
implementation in sysdeps/ieee754/ldbl-128/ by defining _Float128 to
long double. This relied on compiler support for _Float128 being
disabled. On powerpc, such support was disabled by default, however, it
got enabled by default [1] in GCC 8.
This patch copies the implementations from ldbl-128 to ldbl-128ibm. The
uses of _Float128 and L() are kept intact in this patch and are replaced
with a script in a subsequent patch.

powerpc: Add redirection for finitef128, isinf128, and isnanf128
On powerpc64le, compiler support for float128 is not enabled by default
on gcc. To enable it, the flag -mfloat128 must be passed as a command
line option to the compiler. This means that only the few files that
actively have -mfloat128 passed as an argument get compiler support for
float128, whereas all other files don't.
When -mfloat128 becomes enabled by default on powerpc [1], all the files
that do not currently have compiler support for float128 enabled during
their compilation, will start to have it. This will lead to build
errors in s_finite.c, s_isinf.c, and s_isnan.c.
The errors are due to the unintended macro expansion of __finitef128 to
__redirect_finitef128 in math/bits/mathcalls-helper-functions.h. In
that header, __MATHDECL_1 takes '__finite' and 'f128' as arguments and
concatenates them. However, since '__finite' has been redefined in
s_finite.c, the function declaration becomes __redirect_finitef128:
extern int __redirect___finitef128 (_Float128 __value) __attribute__
((__nothrow__ )) __attribute__ ((__const__));
This declaration itself is OK. The problem arises when include/math.h
creates the hidden prototype ('hidden_proto (__finitef128)'), which
expands to:
extern __typeof (__finitef128) __finitef128 __attribute__ ((visibility
("hidden")));
Since __finitef128 is not declared, __typeof fails. This effect was
already true for the 'float' and 'long double' versions and is now true
for float128. Likewise for isinsff128 and isnanf128.
This patch defines __finitef128 as __redirect___finitef128 in
sysdeps/powerpc/powerpc64/fpu/multiarch/s_finite.c, similarly to what's
done for the float and long double versions of these functions, to get
rid of the build error. Likewise for isinff128 and isnanf128.

powerpc64le: Add -mfloat128 to tst-strtod-nan-locale testcase
On powerpc64le, not all files can have the flag -mfloat128 passed as an
option on the compile command, since that could conflict with other
flags, such as -mno-vsx. Each file that needs the flag, gets it through
a CFLAGS-filename variable on sysdeps/powerpc/powerpc64le/Makefile.
The test cases tst-strtod-nan-locale and tst-wcstod-nan-locale are
missing this flag.

Fix BZ# 22180.
POSIX requires that dlclose() and exit() be thread safe, therefore
you can have one thread in the middle of dlclose() and another thread
executing exit() without causing any undefined behaviour on the part
of the implementation.
The existing implementation had a flaw that exit() exit handler processing
did not consider a concurrent dlclose() and would not mark already run
exit handlers using the ef_free flavour. The consequence of this is that
a concurrent exit() with dlclose() will run all the exit handlers that
dlclose() had not yet run, but then will block on the loader lock. The
concurrent dlclose() will continue to run all the exit handlers again
(twice) in violation of the Itanium C++ ABI requirements for __cxa_atexit().
This commit fixes this by having exit() mark all handlers with ef_free to
ensure that concurrent dlclose() won't re-run registered exit handlers that
have already run.

Remove non-add-on Banner files.
Various subdirectories of glibc include Banner files to put some text
in the output of executing libc.so.6, under "Available extensions".
Some of those subdirectories (e.g. crypt) may originally have been
add-ons (and so optional, so a particular glibc build might or might
not have included them), but except for libidn they aren't now (or if
only included in some builds, in the case of soft-fp, the inclusion
depends on the architecture for which glibc is configured rather than
having any glibc configuration for which it's an optional feature),
and it doesn't seem useful for the libc.so.6 output to call out a few
features like that.
This patch removes the non-add-on Banner files, updating contrib.texi

This patch adds SSE4.1 versions of trunc and truncf, using the roundsd

benchtests these are about 30% faster than the C versions for double,
20% faster for float.

Fix powerpc64le problem from last ldbl-opt patch.
This patch fixes a problem on powerpc64le that I missed in initial
testing of my last patch to ldbl-opt. In the specific case of
powerpc64le, the weak aliases for exp10l and remainderl do not get
defined in the generic wrappers because of how those wrappers
undefine and redefine weak_alias. This patch restores those aliases
in the ldbl-opt code.

Use libm_alias_ldouble in math/.
This patch converts libm function implementations in math/ from using
weak_alias to using libm_alias_ldouble to define public function
names, in cases where it would be appropriate to define _Float128 /
_Float64x aliases for those functions as well (in cases where either
or both of those types exist and have the same ABI as long double).
This eliminates many ldbl-opt wrappers round these function
implementations.
Tested for x86_64, and with build-many-glibcs.py. All installed
stripped shared libraries are unchanged except for libm.so on
powerpc64le. As noted for a previous patch, powerpc64le's use of
ldbl-opt means various long double functions get defined using
long_double_symbol which gives them an explicit symbol version in the
object files, and this patch results in some such functions using
weak_alias instead (because powerpc64le never had a previous version
of these functions for long double = double); both produce a valid
libm.so with the same public symbols at the same versions, but macros
expanding to call weak_alias is cleaner in this case.

AArch64: use movz/movk instead of literal pools in start.S
eXecute-Only Memory (XOM) is a protection mechanism against some ROP
attacks. XOM sets the code as executable and unreadable, so the access
to any data, like literal pools, in the code section causes the fault
with XOM. The compiler can disable literal pools for C source files,
but not for assembly files, so I use movz/movk instead of literal pools
in start.S for XOM.
I add MOVL macro with movz/movk instructions like movl pseudo-instruction
in armasm, and use the macro instead of literal pools.
* sysdeps/aarch64/start.S: Use MOVL instead of literal pools.
* sysdeps/aarch64/sysdep.h (MOVL): Add MOVL macro.

Use libm_alias_double in math/.
This patch converts libm function implementations in math/ from using
weak_alias to using libm_alias_double to define public function names,
in cases where it would be appropriate to define _Float64 / _Float32x
aliases for those functions as well. This eliminates many
NO_LONG_DOUBLE conditionals and ldbl-opt wrappers round these function
implementations.
Tested for x86_64. Also tested with build-many-glibcs.py. Binary
differences seen are that the different order in which remainder and
drem symbols get defined as a result of this patch (the same source
file defines the same aliases, but in a different order of definition)
changes the order of symbols in the final libm.so when long double =
double, and for ldbl-opt configurations, the compat symbols for Bessel
functions were previously defined by e.g. "compat_symbol (libm, j0,
j0l, GLIBC_2_0)", which declares j0l as a compat symbol based on j0
and so makes j0l weak because j0 is weak, and are now defined
(indirectly via the relevant macros) based on e.g. __j0, so are no
longer weak because __j0 isn't weak.

Remove ENOSYS math/ function stubs.
The math/ directory has various stub implementations of functions
(generally long double functions, plus sqrtf128) that set errno to
ENOSYS and print a message.
These are a relic of when the long double libm implementation in glibc
was originally incomplete. They are only present for a limited set of
libm functions, not all those that would need implementing for any
hypothetical new long double format, and only for long double (plus
sqrtf128), not for other floating-point types. I removed the
corresponding ENOSYS tests in the testsuite in
<https://sourceware.org/ml/libc-alpha/2013-05/msg00599.html>.
I think these stubs are an inherently different case from stubs for
functionality needing OS-specific implementations, since
floating-point formats are generally standardized between modern
processors (a new long double format does not seem likely - I'd expect
new ports all to have long double = binary128 or long double =
binary64 - though _Float16 functions *f16 are entirely possible in
future) and libm functions are generally only expected to fail for
domain / range / pole errors, not for other unknown system-specific
conditions the way the functions needing OS-specific implementations
may fail.
This patch removes these stub implementations. The effect (which, as
noted above, was actually mostly already the case, given the
incompleteness of the set of stubs, and was certainly the case if you
wanted your libm port to *work* rather than just build) is that any
new long double format needs to provide a full set of functions for
the build to succeed; any port using ldbl-128 needs to provide sqrtl
(possibly using the soft-fp version from another port); any port using
ldbl-96 needs to provide all those functions that all of
x86_64/i386/ia64/m68k provide rather than getting from the ldbl-96
directory; any port with _Float128 as a type with a distinct format
needs to provide sqrtf128.
Tested for x86_64. Also tested with build-many-glibcs.py that
installed stripped shared libraries are unchanged by the patch.

[BZ #21745] powerpc: build some IFUNC math functions for libc and libm
Some math functions have to be distributed in libc because they're
required by printf.
libc and libm require their own builds of these functions, e.g. libc
functions have to call __stack_chk_fail_local in order to bypass the
PLT, while libm functions have to call __stack_chk_fail.
While math/Makefile treat the generic cases, i.e. s_isinff, the
multiarch Makefile has to treat its own files, i.e. s_isinff-ppc64.

previous contents of sysdep_routines, but re-sorted..

defined in sysdep_calls and replace by the respective m_* names.
* sysdeps/powerpc/powerpc64/fpu/multiarch/s_isnan-ppc64.S:

Use libm_alias_float in math/.
This patch converts libm function implementations in math/ from using
weak_alias to using libm_alias_float to define public function names,
in cases where it would be appropriate to define _Float32 aliases for
those functions as well. expf and exp2f are omitted from this patch,
given the in-progress patches that would change their symbol
versioning arrangements (at a later stage it will be necessary to add
macros that can be used for functions with such symbol versioning
arrangements - which will apply to lgammaf as well - but for the
initial patches in this area I'm just dealing with easy cases, and any
symbol versioning changes to these functions while the work is in
progress can effectively just undo the libm_alias_* changes as regards
those functions).
Tested for x86_64. Also tested with build-many-glibcs.py that
installed stripped shared libraries are unchanged by the patch.

Make more libm functions into weak aliases.
Many libm functions define the function as __<func> and then define
<func> as a weak alias. This is not at all limited to cases where
there is an internal call that has namespace reasons to need to call
__<func> instead of <func>.
The common macros for creating libm function aliases work on the basis
of public function names all being aliases; that is, they define
aliases for functions using the above pattern. Thus, where a function
just defines the public name <func> directly, changing that to be a
weak alias enables a subsequent conversion to the common macros to
retain the exact existing symbols (and so be testable by comparison of
stripped binaries).
This patch converts many existing functions to use the weak alias
pattern, as preparation for subsequent conversions to common macros.
I do expect that _FloatN/_FloatNx function aliases will end up needing
new variants of the common macros that do *not* create the original
float / double / long double name of a function - for cases where that
name is created specially to give it a particular symbol version, for
example - but for functions that can use the most common macros to
create all the public names as aliases, it makes sense for them to do
so.
Regarding the Bessel function wrappers in this patch: only float and
double wrappers are changed because the long double wrappers already
used the weak alias pattern.
Tested for x86_64, and with build-many-glibcs.py.

Add new codepage charmaps/IBM858 [BZ #21084]
This code page is identical to code page 850 except that X'D5'
has been changed from LI61 (dotless i) to SC20 (euro symbol).
The code points from /x01 to /x1f in the /localedata/charmaps/IBM858
file have the same mapping as those in localedata/charmaps/ANSI_X3.4-1968.
That means they disagree with with
ftp://ftp.software.ibm.com/software/globalization/gcoc/attachments/CP00858.txt
in that range.
For example, localedata/charmaps/IBM858 and
localedata/charmaps/ANSI_X3.4-1968 have:
â<U0001> /x01 START OF HEADING (SOH)â
whereas CP00858.txt has:
â01 SS000000 Smiling Faceâ
That means that CP00858.txt is not really ASCII-compatible and to make
it ASCII-compatible we deviate fro CP00858.txt in the code points from /x01
to /x1f.

Define and use libm_alias_float128.
Continuing the process of setting up common macros for libm function
aliases, with a view to using them to define _FloatN / _FloatNx
aliases in future, this patch adds a libm_alias_float128 macro and
uses it in the type-generic templates. (_Float128 functions will end
up with _Float64x aliases on powerpc64le, but not on x86_64/x86/ia64
because _Float64x has long double format there, and the macro will
provide a single place for the conditionals for that choice, as well
as for once ldbl-128 functions always build *f128 and need
conditionals for whether to have *l aliases.)

installed stripped shared libraries are unchanged by the patch.

Continuing the process of setting up common macros for libm function
aliases, with a view to using them to define _FloatN / _FloatNx
aliases in future, this patch adds a libm_alias_ldouble macro and uses

Since math-type-macros-ldouble.h already did the appropriate thing for
each symbol (weak_alias or long_double_symbol), this is just a
straightforward rearrangement of code, to make the required logic
available in a place that can also be used outside of the type-generic
templates in future (in particular, to eliminate various wrappers for
functions in ldbl-opt and ldbl-64-128).

Clear up log1p, ldexp, scalbn, scalbln compat handling.
This patch cleans up how compat symbols / long double versioning are
handled for log1p, ldexp, scalbn and scalbln functions.
The general principle is to do as much as possible through the
type-generic templates. Previously, when errno-setting wrappers were
added the compat long double symbols were left pointing directly to
the underlying implementations; they are moved to point to the
errno-setting wrappers. For the functions also present in libc,
compat symbol handling for the libc copies needs to go in ldbl-opt
wrappers, but the type-generic templates can handle it for the libm
copies. There is no need for w_scalbln_template.c to disable the
creation of an unused internal alias (such code made sense in the
context of patches trying to avoid any changes to generated code for
ease of comparison, but can be removed in a change that specifically
does intend to change details of where symbols point).
Tested for x86_64, and with build-many-glibcs.py.

- Add a compat implementation on s390 to avoid the architecture
to build the symbols on default linux oldglob.c by setting
GLOB_NO_OLD_VERSION.
- Remove the duplicate rule to build oldglob on alpha.

Define and use libm_alias_double.
Continuing the process of setting up common macros for libm function
aliases, with a view to using them to define _FloatN / _FloatNx
aliases in future, this patch adds a libm_alias_double macro and uses
it in the type-generic templates.
This macro handles defining aliases for double, and for long double in
the NO_LONG_DOUBLE case. It also handles defining compat symbols for
long double = double for architectures that changed their long double
format. By so doing, it eliminates the need for the
M_LIBM_NEED_COMPAT and declare_mgen_libm_compat macros; the single
declare_mgen_alias call in each template now suffices to define all
required compat symbols. When used for more double functions (not
based on type-generic templates), I expect it will eliminate the need
for most ldbl-opt wrappers for such functions.
A few special cases are needed. __clog10l is a public symbol (for
historical reasons) so needs to be given appropriate compat versions
for architectures that changed their long double format, but is not
defined as an alias using the normal macros since __clog10* are *not*
public symbols for _FloatN / _FloatNx types. For scalbn, scalbln and
log1p, the changes adding errno setting support for those functions
left compat symbols pointing directly to the non-errno-setting
implementations. There is no requirement for the compat symbols not
to set errno; that just made for the simplest patches at that time.
Now, with these common macros, it's natural to redirect the compat
symbols to the errno-setting wrappers, which I intend to do in a
separate patch.
Tested for x86_64, and with build-many-glibcs.py. For ldbl-opt
platforms the stripped libm.so binaries are changed (disassembly
unchanged) because the details of how the clog10l compat symbol is
created mean it ceases to be weak as it was before; for other
platforms, stripped libm.so binaries are unchanged.

Remove declare_mgen_alias_2.
The libm template machinery includes a macro declare_mgen_alias_2, to
define two function aliases rather than one. This macro is only used
in one place, to define ldexp and scalbn, and only has one nondefault
definition, for double in the case where long double has the same
format. That definition is because declare_mgen_alias for double, in
that case, defines <internal-func>l as an alias of <internal-func>, so
cannot be called twice for aliases of the same function.
Now, I suspect the <internal-func>l aliases are generally not needed
(with maybe a few exceptions such as __clog10l, which is an exported
function). But even in the presence of them, there is no need for a
special declare_mgen_alias_2 macro for this case. This patch
eliminates the need for such a macro by defining __wrap_scalbn<suffix>
as an alias of __ldexp<suffix>, and then using that when defining the
scalbn public aliases. This is similar to how such internal aliases
are created for functions with multiple symbol versions, for example.
Tested for x86_64, and with build-many-glibcs.py. (There *are* some
cases where installed stripped shared libraries change - not in the
generated code but because such changes to static symbols on input to
ld, even nonexported symbols that don't affect the code or dynamic
symbols, can affect the particular representation in the output of
string tables, hash tables etc.)

x86: Add MathVec_Prefer_No_AVX512 to cpu-features [BZ #21967]
AVX512 functions in mathvec are used on machines with AVX512. An AVX2
wrapper is also provided and it can be used when the AVX512 version
isn't profitable. MathVec_Prefer_No_AVX512 is addded to cpu-features.
If glibc.tune.hwcaps=MathVec_Prefer_No_AVX512 is set in GLIBC_TUNABLES
environment variable, the AVX2 wrapper will be used.
Tested on x86-64 machines with and without AVX512. Also verified
glibc.tune.hwcaps=MathVec_Prefer_No_AVX512 on AVX512 machine.

Define and use a libm_alias_float macro.
Fully supporting TS 18661-3 _FloatN / _FloatNx types in the cases
where they have the same format as other supported types (in line with
the principles described at
<https://sourceware.org/ml/libc-alpha/2017-01/msg00333.html>) means
adding a lot of function aliases to libm (and a few to libc). float
functions will have *f32 aliases, double functions will have *f32x and
*f64 aliases, long double functions may have *f64x, *f128 or both
aliases depending on the configuration, float128 functions have have
*f64x aliases depending on the configuration.
At present, most individual libm functions have their own weak_alias
calls to define the public names for those functions. For TS 18661-3
support, it is desirable that functions not all need to duplicate the
logic for which alias names to define.
Thus, common macros for defining the public aliases to a libm function
make sense. In the double and long double cases, such macros will
also help simplify existing code (with LONG_DOUBLE_COMPAT
etc. conditionals), by eliminating existing conditionals and ldbl-opt
/ ldbl-64-128 wrappers (using the generated ldbl-compat-choose.h to
allow a single macro definition to expand appropriately for each
symbol depending on LONG_DOUBLE_COMPAT for that symbol).
This patch starts the process of adding such macros with a
straightforward case: a libm_alias_float macro, initially only used in
the case of type-generic templates, to define aliases for float
functions (currently just the *f public names, in future also *f32).
Future patches are intended to add such macros for other types and to
extend the cases in which they are used, with a view to as many places
as possible using them before support for _FloatN / _FloatNx aliases
is enabled. (I think it's inevitable that some places doing
architecture-specific things with aliases and symbol versioning may
end up needing to replicate logic for the new aliases, but hopefully
the number of such places can be kept to a minimum.)
The libm_alias_float macro takes unsuffixed names for both the
internal and public function names. The need for unsuffixed public
names is obvious, since such macros will end up defining multiple
public names with different suffixes. Unsuffixed internal names are
because I expect the ldbl-128 functions to end up in a form that
always defines *f128 names and sometimes also defines *l names - with
the main internal names being e.g. __ieee754_<func>f128 (so many
macros in float128_private.h can go away). But __ieee754_<func>l
aliases will still be needed for e.g. use from math/ complex
functions, meaning the alias macro needs to see just __ieee754_<func>
as internal name so it can create an alias based on that name. Since
libm_alias_float128 will thus need the unsuffixed internal name, it
seems to make sense for all such macros to receive the unsuffixed
name.
Tested for x86_64. Also tested with build-many-glibcs.py that
installed stripped shared libraries are unchanged by the patch.

x86: Add x86_64 to x86-64 HWCAP [BZ #22093]
Before glibc 2.26, ld.so set dl_platform to "x86_64" and searched the
"x86_64" subdirectory when loading a shared library. ld.so in glibc
2.26 was changed to set dl_platform to "haswell" or "xeon_phi", based
on supported ISAs. This led to shared library loading failure for
shared libraries placed under the "x86_64" subdirectory.
This patch adds "x86_64" to x86-64 dl_hwcap so that ld.so will always
search the "x86_64" subdirectory when loading a shared library.
NB: We can't set x86-64 dl_platform to "x86-64" since ld.so will skip
the "haswell" and "xeon_phi" subdirectories on "haswell" and "xeon_phi"
machines.
Tested on i686 and x86-64.

Add fcntl sealing interfaces from Linux 3.17 to bits/fcntl-linux.h.
While reviewing Linux 4.13 for glibc header changes needed, I noticed
that bits/fcntl-linux.h was missing F_ADD_SEALS etc. from Linux 3.17.
I didn't find any discussion indicating this omission is deliberate.
Now, these interfaces can only be used with file descriptors created
with memfd_create, and we don't have a memfd_create wrapper in glibc
(a patch was submitted in October 2014, albeit without documentation /
tests, and discussions continued over the next few months, but without
consensus on whether to add the interface - and we still lack any
general consensus on syscall wrappers), but I don't think that's a
reason to exclude the constants from bits/fcntl-linux.h (especially as
the header does not look compatible with simultaneously including
linux/fcntl.h).
(Some of those 2014/2015 discussions raised concerns about difficulty
using the memfd_create / sealing interface, but those seem to me more
like a question of whether it should be part of the OS-independent GNU
API - in my view, even fairly specialized syscalls ought to have
wrappers added to glibc if not obsolescent, but there may be cases
where we only want to include them in the Linux-specific API and
anything in the OS-independent GNU API should be different - rather
than being relevant to whether constants for use with fcntl should
appear in headers.)

posix: Consolidate Linux glob implementation
This patch consolidates the glob implementation. The main changes are:
* On Linux all implementation now uses the default one at
sysdeps/unix/sysv/linux/glob{free}{64}.c with the exception
of alpha (which requires specific versioning) and s390-32 (which
different than other 32 bits ports it does not add a compat one
symbol for 2.1 version).
* The default implementation uses XSTAT_IS_XSTAT64 to define whether
both glob{free} and glob{free}64 should be different implementations.
For archictures that define XSTAT_IS_XSTAT64, glob{free} is an alias
to glob{free}64.
* Move i386 olddirent.h header to Linux default directory, since it is
the only header with this name and it is shared among different

posix: Allow glob to match dangling symlinks [BZ #866]
This patch makes glob match dangling symlinks. Compared to other glob
implementation (*BSD, bash, musl, and other shells as well), GLIBC seems
the be the only one that does not match dangling symlinks. As for
comment #5 in BZ #866, POSIX does not have any strict specification for
dangling symlinks match and it is reasonable that trying to glob everything
in a path should return all types of files (such as for a 'rm *'). Also,
comment #7 shows even more example where GLIBC current behavior is
unexepected.
I avoided adding another GNU specific flag to set this behavior and
instead make it the default. Although this change the semanthic from
previous implementation, I think adding another compat symbol to be
really unecessary as from aforementioned reasons (current behavior not
defined in any standard, general idea of different implementation is
to list dangling symbols).
This also sync glob with gnulib commit fd1daf4 (glob: match dangling
symlinks).

Prefer new libm function wrappers for !LIBM_SVID_COMPAT.
The initial obsoletion of SVID libm error handling left the old
wrappers and __kernel_standard still being used for new ports and
static linking, just with macro definitions of _LIB_VERSION and
matherr that meant symbols with those names were never actually used
and the code for different error handling variants could be optimized
out.
This patch cleans things up further by eliminating the
__kernel_standard use for new ports and static linking. Now, the old
wrappers no longer generate any code in the !LIBM_SVID_COMPAT case,
while the new errno-only wrappers that were added for float128 support
are now also used for float, double and long double in that case.
The changes are generally straightforward. The w_scalb*_compat
wrappers continue to be used (scalb is obsolescent in the sense of not
being supported for float128, but is present in supported standards -
the 2001 edition of POSIX and earlier XSI versions - so remains
supported for static linking and new ports, as do the float and long
double variants that are existing GNU extensions). Those wrappers
would only call __kernel_standard in the _LIB_VERSION == _SVID_ case.
Since we would like to be able to compile most of glibc without
optimization, relying on a static function whose only use is under an
if (0) condition being optimized away to avoid an undefined
__kernel_standard reference may not be a good idea. Thus, the
relevant code in the scalb wrappers has LIBM_SVID_COMPAT conditionals
added to guarantee it's not built at all in the case where
__kernel_standard does not exist.
Just as i386 has its own w_sqrt_compat.c, so w_sqrt.c is also added.
ia64 gets dummy w_*.c to prevent those files being built where they
would conflict with the ia64 libm, as with its existing w_*_compat.c.
Conditions disabling code for !LIBM_SVID_COMPAT are needed in both the
math/ wrappers and in the long double wrappers in ldbl-opt (to avoid
them setting up aliases and symbol versions for undefined symbols). I
hope that future cleanups to how libm function aliases and symbol
versioning are done will eliminate the need for most of the ldbl-opt
wrappers.

Fix pcprofiledump cross-endian condition (bug 22086).
debug/pcprofiledump.c contains code that tries to handle other-endian
data. This uses a condition "(word & 0xfffffff0) == bswap_32
(0xdeb00000)". This condition is always false (the LHS always has the
low four bits zero, the RHS doesn't); a correct comparison would use
0x0fffffff. This results in -Werror=tautological-compare build

pcprofiledump.c: In function 'main':

This patch fixes the condition. Tested for x86_64, and with
build-many-glibcs.py that it fixes the build for tilegx-linux-gnu.
(Note that I have not tested the actual pcprofiledump functionality,
native or cross endian, which lacks any testsuite coverage.)

math.h: Warn about an already-defined log macro
This is a common programming error, and the cause of the problem is not

<tgmath.h> defines a log macro, but it includes <math.h> before that, so
that is compatible with the warning.

Obsolete pow10 functions.
This patch obsoletes the pow10, pow10f and pow10l functions (makes
them into compat symbols, not available for new ports or static
linking). The exp10 names for these functions are standardized (in TS
18661-4) and were added in the same glibc version (2.1) as pow10 so
source code can change to use them without any loss of portability.
Since pow10 is deliberately not provided for _Float128, only exp10,
this slightly simplifies moving to the new wrapper templates in the
!LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10,
pow10f and pow10l to be defined by those templates.

Remove NO_CANCELLATION macro
The NO_CANCELLATION macro is used currently on generic headers to
define non cancellable syscalls and on Linux fcntl to implement the non
cancellable variation. Former should be single-handled by not-cancel.h
header and former could be simplified build both cancellable and non
cancellable for default objects and alias the non-cancellable to default
one for rtld ones (since Linux already support cancellation as default).
This patch thus removes the NO_CANCELLATION macro and its usage. The
generic non cancellable fcntl is route to internal fcntl.
Checked on x86_64-linux-gnu and i686-linux-gnu. Also checked with
a build again major ABIs.

Simplify NAN definitions.
Similar to my patches for HUGE_VAL and INFINITY. this patch eliminates
the bits/nan.h headers. __builtin_nanf ("") is used to define NAN for
GCC 3.3 and later; the fallback is (0.0f / 0.0f), which is a constant
expression for a quiet NaN of type float, but raises a spurious
"invalid" exception outside static initializers, which seems the best
that can be done purely in standard C. Again, if anyone actually uses
a compiler with its own incompatible extension for producing a
constant quiet NaN, we can add compiler conditionals.
Tested for x86_64.

Simplify INFINITY definitions.
Similar to my patch for HUGE_VAL, this patch eliminates the bits/inf.h
headers and just unconditionally uses the same definitions as the
sysdeps/ieee754 version did (__builtin_inff () for GCC >= 3.3,
otherwise HUGE_VALF), directly in math.h, so removing an unnecessary
level of indirection.
Tested for x86_64.

commit a60eca2e55e2372e21f0d19b1dc5cac61a48ee50
Author: Joseph Myers <address@hidden>
Date: Thu Aug 31 15:50:50 2017 +0000
Simplify HUGE_VAL definitions.
There are various bits/huge_val*.h headers to define HUGE_VAL and
related macros. All of them use __builtin_huge_val etc. for GCC 3.3
and later. Then there are various fallbacks, such as using a large
hex float constant for GCC 2.96 and later, or using unions (with or
without compound literals) to construct the bytes of an infinity, with
this last being the reason for having architecture-specific files.
Supporting TS 18661-3 _FloatN / _FloatNx types that have the same
format as other supported types will mean adding more such macros;
needing to add more headers for them doesn't seem very desirable.
The fallbacks based on bytes of the representation of an infinity do
not meet the standard requirements for a constant expression. At
least one of them is also wrong: sysdeps/sh/bits/huge_val.h is
producing a mixed-endian representation which does not match what GCC
does.
This patch eliminates all those headers, defining the macros directly
in math.h. For GCC 3.3 and later, the built-in functions are used as
now. For other compilers, a large constant 1e10000 (with appropriate
suffix) is used. This is like the fallback for GCC 2.96 and later,
but without using hex floats (which have no apparent advantage here).
It is unambiguously valid standard C for all floating-point formats
with infinities, which covers all formats supported by glibc or likely
to be supported by glibc in future (C90 DR#025 said that if a
floating-point format represents infinities, all real values lie
within the range of representable values, so the constraints for
constant expressions are not violated), but may generate compiler
warnings and wouldn't handle the TS 18661-1 FENV_ROUND pragma
correctly. If someone is actually using a compiler with glibc that
does not claim to be GCC 3.3 or later, but which has a better way to
define the HUGE_VAL macros, we can always add compiler conditionals in
with alternative definitions.
I intend to make similar changes for INF and NAN. The SNAN macros
already just use __builtin_nans etc. with no fallback for compilers
not claiming to be GCC 3.3 or later.
Tested for x86_64.

Fix mcontext_t sigcontext namespace (bug 21457).
This patch completes the ucontext.h namespace fixes by fixing issues
related to the use of struct sigcontext as mcontext_t, and inclusion
of <bits/sigcontext.h> even when struct sigcontext is not so used.
Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the
way to get the sigcontext structure is by including <signal.h> (in a
context where __USE_MISC is defined); the sysdeps/generic version of
sys/ucontext.h keeps the inclusion by necessity, with a comment about
how this is not namespace-clean, but the only configuration that used
it, MicroBlaze, gets its own version of the header in this patch.
Where mcontext_t was typedefed to struct sigcontext, the contents of
struct sigcontext are inserted (with appropriate namespace handling to
prefix fields with __ when __USE_MISC is not defined); review should
check that this has been done correctly in each case, whether the
definition of struct sigcontext comes from glibc headers or from the
Linux kernel. This changes C++ name mangling on affected
architectures (which do not include x86_64/x86).
Tested for x86_64, and with build-many-glibcs.py.

Fix m68k bits/math-inline.h macro namespace (bug 22035).
As shown by build bot failures
<https://sourceware.org/ml/libc-testresults/2017-q3/msg00349.html> the
m68k bits/mathinline.h is not namespace-clean: it fails to compile if
the user has defined macros f or l before it is included, because of
expansions of those arguments to __inline_functions. This patch
changes the __inline_functions definitions to take not the suffix but
a macro that concatenates it with the function name, to avoid the
spurious macro expansions.
Tested for m68k with build-many-glibcs.py.
[BZ #22035]

MIPS/o32: Fix internal_syscall5/6/7
Fix a commit cc25c8b4c119 ("New pthread rwlock that is more scalable.")
regression and prevent uncontrolled stack space usage from happening
when a 5-, 6- or 7-argument syscall wrapper is placed in a loop.
The cause of the problem is the use of `alloca' in regular MIPS/Linux
wrappers to force the use of the frame pointer register in any function
using one or more of these wrappers. Using the frame pointer register
is required so as not to break frame unwinding as the the stack pointer
is lowered within the inline asm used by these wrappers to make room for
the stack arguments, which 5-, 6- and 7-argument syscalls use with the
o32 ABI.
The regular MIPS/Linux wrappers are macros however, expanded inline, and
stack allocations made with `alloca' are not discarded until the return
of the function they are made in. Consequently if called in a loop,
then virtual memory is wasted, and if the loop goes through enough
iterations, then ultimately available memory can get exhausted causing
the program to crash.
Address the issue by replacing the inline code with standalone assembly
functions, which rely on the compiler arranging syscall arguments
according to the o32 function calling convention, which MIPS/Linux
syscalls also use, except for the syscall number passed and the error
flag returned. This way there is no need to fiddle with the stack
pointer anymore and all that has to be handled in the new standalone
functions is the special handling of the syscall number and the error
flag.
Redirect 5-, 6- or 7-argument MIPS16/Linux syscall wrappers to these new
functions as well, so as to avoid an unnecessary double call the
existing wrappers would cause with the new arrangement.

This patch fixes ia64 failures on thread exit by madvise the required

(NEED_SEPARATE_REGISTER_STACK). Also the snippet that setup the
madvise call to advertise kernel the area won't be used anymore in
near future is reallocated in allocatestack.c (for consistency to
put all stack management function in one place).
Checked on x86_64-linux-gnu and i686-linux-gnu for sanity (since
it is not expected code changes for architecture that do not

Fix bits/math-finite.h _MSUF_ expansion namespace (bug 22028).
The current bits/math-finite.h approach to defining functions for
different types, involving math.h defining _MSUF_ and _MSUFTO_ for the
function suffixes involved, is not namespace-clean if one of those
suffixes (f, l, f128) is defined as a macro by the user before math.h
is included; too many levels of macro expansion occur. Instead, those
suffixes should appear directly in the expansion of the macro using ##
so they don't get expanded even if defined as macros by the user (that
is, math.h should be defining __REDIRFROM_X and __REDIRTO_X directly
to use those suffixes rather than suffixes being passed as an argument
by macro callers). This patch makes that change.
Tested for x86_64.

Provide a C++ version of iszero that does not use __MATH_TG (bug 21930)
When signaling nans are enabled (with -fsignaling-nans), the C++ version
of iszero uses the fpclassify macro, which is defined with __MATH_TG.
However, when support for float128 is available, __MATH_TG uses the
builtin __builtin_types_compatible_p, which is only available in C mode.
This patch refactors the C++ version of iszero so that it uses function
overloading to select between the floating-point types, instead of
relying on fpclassify and __MATH_TG.
Tested for powerpc64le, s390x, x86_64, and with build-many-glibcs.py.

Simplify math-svid-compat code.
Now there are no more assembly wrappers using _LIB_VERSION or
__kernel_standard, the math-svid-compat code can be slighly
simplified. math-svid-compat.h no longer needs __ASSEMBLER__
conditionals, and the _LIB_VERSION variable no longer needs to be
built for static libm, since all references are now in C code that
includes math-svid-compat.h and so gets the macro definition of
_LIB_VERSION to _POSIX_ outside the compat case. This patch makes
those cleanups.

<bits/syscall.h>: Use an arch-independent system call list on Linux
This commit changes the way the list of SYS_* system call macros is
created on Linux. glibc now contains a list of all known system
calls, and the generated <bits/syscall.h> file defines the SYS_ macro
only if the correspnding __NR_ macro is defined by the kernel headers.
As a result, glibc does not have to be rebuilt to pick up system calls
if the glibc sources already know about them. This means that glibc
can be built with older kernel headers, and if the installed kernel
headers are upgraded afterwards, additional SYS_ macros become
available as long as glibc has a record for those system calls.

Use __HAVE_DISTINCT_FLOAT128 in tgmath.h.
When _Float128 is ABI-equivalent to long double, there is no need for
tgmath.h to have any special _Float128 handling: it's always OK to
call the long double versions of functions for _Float128 arguments in
that case, and the logic to determine return types is generic. Thus,
this patch changes the use of __HAVE_FLOAT128 to
__HAVE_DISTINCT_FLOAT128, as a minor optimization to reduce the size
of the macro expansions in the ABI-equivalent case.
Tested for x86_64.
* math/tgmath.h [__HAVE_FLOAT128]: Change conditional to

Clean up bits/math-finite.h for aliasing types.
This patch cleans up how bits/math-finite.h handles types that are
ABI-aliases of other types.
For such types, no __*_finite functions exist; instead,
bits/math-finite.h must redirect calls to a the functions for a
canonical choice of type for each floating-point format. (For the
actual public interfaces, symbols need exporting for each type, even
those that are ABI-aliases, because of standard requirements that
programs can declare the functions themselves without including
<math.h>, but that does not apply to __*_finite.)
At present, there is a special-case conditional in bits/math-finite.h
on __MATH_DECLARING_LDOUBLE && defined __NO_LONG_DOUBLE_MATH to handle
redirecting long double function calls to double __*_finite. This
patch replaces this by a more general mechanism. math.h, before each
inclusion of bits/math-finite.h, defines _MSUFTO_ as the suffix to use
on the target of redirection, in addition to the existing _MSUF_.
This way, __MATH_DECLARING_LDOUBLE can go away, as can the special
conditional in bits/math-finite.h. With this patch, math.h is now
prepared for the case of supporting float128 functions as aliases of
long double ones on platforms where long double is binary128, with
_MSUFTO_ appropriately defined for that case, and appropriate _MSUFTO_
definitions can easily be included when supporting _Float32 / _Float64
/ _Float32x / _Float64x (which will always be ABI-aliases of another
type when supported).
Tested for x86_64, and did a compilation test for ARM with
build-many-glibcs.py to cover the long double = double case.

Remove powerpc32 sqrt wrappers.
This patch removes the powerpc32-specific wrappers for sqrt and sqrtf.
These wrappers, by adding architecture-specific uses of _LIB_VERSION
and __kernel_standard, unnecessarily complicate cleanups of libm error
handling. They also do not serve a useful optimization purpose. GCC
knows about sqrt as a built-in function, and can generate direct calls
to a hardware square root instruction, either on its own, in the
-fno-math-errno case, or together with an inline check for the
argument being negative and a call to the out-of-line sqrt function
for error handling only in that case (and has been able to do so for a
long time). Thus in practice the wrapper will only be called only in
the case of negative arguments, which is not a case it is useful to
optimize for.
Tested with build-many-glibcs.py for powerpc-linux-gnu-power4.

Fix the C++ version of issignaling when __NO_LONG_DOUBLE_MATH is defined
When __NO_LONG_DOUBLE_MATH is defined, __issignalingl is not available,
thus issignaling with long double argument should call __issignaling,
instead.
Tested for powerpc64le.

double case, call __issignalingl only if __NO_LONG_DOUBLE_MATH

Remove cancellation support for syscall generation
This patch removes the cancellation mark from the auto-generation syscall
script. Now all the cancellable syscalls are done throught C code using
the SYSCALL_CANCEL macro. It simplifies the assembly required to each
architecture port, since the SYSCALL_CANCEL uses the already defined
INLINE_SYSCALL macros, and allows a more straigh fix on cancellation
machanism (since no more specific assembly fixes will be required).
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.A

Fix remaining return type of ifunc resolver declaration

Declare ifunc resolver to return a pointer to the same type as the
target
function to help GCC detect incompatibilities between the two when it's
enhanced to do so.
builds for powerpc64le fail in the declaration of some ifunc resolvers,
because the ifunc is declared with unmatching return types. One of the
declarations comes from the __ifunc_resolver macro, which was patched by
the aforementioned commit:
/* Helper / base macros for indirect function symbols. */
#define __ifunc_resolver(type_name, name, expr, arg, init, classifier) \
classifier inhibit_stack_protector \
__typeof (type_name) *name##_ifunc (arg) \
whereas the other comes from the unpatched __ifunc macro when
HAVE_GCC_IFUNC is not defined:
# define __ifunc(type_name, name, expr, arg, init) \
extern __typeof (type_name) name; \
void *name##_ifunc (arg) __asm__ (#name); \
This patch changes the return type of the ifunc resolver in the __ifunc
macro, so that it matches the return type of the target function,
similarly to what the aforementioned commit does.
Tested for powerpc64le and s390x with unpatched GCC.
* include/libc-symbols.h: [!defined HAVE_GCC_IFUNC] (__ifunc):
Change the return type of the ifunc resolver to match the return
type of the target function.

Fix {INLINE,INTERNAL}_SYSCALL macros for x32
The problem for x32 is the {INTERNAL,INLINE}_SYSCALL C macros explicit
cast the arguments to 'long int', thus passing as 32 bits arguments
that should be passed to 64 bits.
Previous x32 implementation uses the auto-generated syscalls from
assembly macros (syscalls.list), so the {INTERNAL,INLINE}_SYSCALL
macros are never used with 64 bit argument in x32 (which are
internally broken for this ILP).
To fix it I used a strategy similar to MIPS64n32 (although both
ABI differs for some syscalls on how top pass 64-bits arguments)
where argument types for kernel call are defined using GCC extension
'typeof' with a arithmetic operation. This allows 64-bits arguments
to be defined while 32-bits argument will still passed as 32-bits.
I also cleanup the {INLINE,INTERNAL}_SYSCALL definition by defining
'inline_syscallX' instead of constructing the argument passing using
macros (it adds some readability) and removed the ununsed
INTERNAL_SYSCALL_NCS_TYPES define (since the patch idea is exactly to
avoid requiric explicit types passing).
Tested on x86_64 and x32.

powerpc: Shrink ULPs for float128
During the development of float128 on powerpc64le, the ulps have been
generated since early versions of the patches. On those versions, the
functions gamma and pow10 were mistakenly thought to be part of the API.
After review, the functions were removed, however the ulps for them were
carried in the ulps file.
This patch removes such entries from the ulps file, as well as it
shrinks the ulps for the cpow and lgamma functions.
Tested for powerpc64le.

Fix tgmath.h handling of complex integers (bug 21684).
The tgmath.h macros return a real type not a complex type when an
argument is of complex integer type (a GNU extension) and there are no
arguments of complex floating type. It seems clear that just as real
integers are mapped to double for tgmath.h, so complex integers should
be mapped to _Complex double.
This patch implements such a mapping. The main complication in fixing
this bug is that the tgmath.h macros expand their arguments a large
number of times, resulting in exponential blowup of the size of the
expansion when calls to tgmath.h macros are used in the arguments of
such macros; it would be unfortunate for fixing a bug with a fairly
obscure extension to make the macros expand their arguments even more
times. Thus, this patch optimizes the definitions of the relevant
macros. __tgmath_real_type previously expanded its argument 7 times
and now expands it 3 times. __tgmath_complex_type, used in place of
__tgmath_real_type only for functions that might return either real or
complex types, not for complex functions that always return real types
or always return complex types, expands its argument 5 times. So the
sizes of the macro expansions from nested macro calls are
correspondingly reduced (remembering that each tgmath.h macro expands
__tgmath_real_type, or sometimes now __tgmath_complex_type, several
times).
Sometimes the real return type resulted from calling a complex
function and converting the result to a real type; sometimes it
resulted from calling a real function, because the logic for
determining whether arguments were real or complex, based on sizeof,
was confused by integer promotions applying to e.g. short int but not
_Complex short int. The relevant tests are converted to use a new
macro __expr_is_real, which, by calling __builtin_classify_type rather
than comparing the results of two calls to sizeof, also reduces the
number of times macros expand their arguments.
Although there are reductions in the number of times macros expand
their arguments, I do not consider this to fix bug 21660, since a
proper fix means each macro expanding its arguments only once (via
using new compiler features designed for that purpose).
Tested for x86_64.

Provide a C++ version of issignaling that does not use __MATH_TG
The macro __MATH_TG contains the logic to select between long double and
_Float128, when these types are ABI-distinct. This logic relies on
__builtin_types_compatible_p, which is not available in C++ mode.
On the other hand, C++ function overloading provides the means to
distinguish between the floating-point types. The overloading
resolution will match the correct parameter regardless of type
qualifiers, i.e.: const and volatile.
Tested for powerpc64le, s390x, and x86_64.
* math/math.h [defined __cplusplus] (issignaling): Provide a C++

Refactor long double information into bits/long-double.h.
resulted in sparc32 configurations installing the ldbl-opt version of
bits/long-double.h instead of the intended
sysdeps/unix/sysv/linux/sparc version.
For sparc32 by itself, this is not a problem, since the ldbl-opt
version is correct for sparc32. However, both sparc32 and sparc64 are
supposed to install sets of headers that work for both of them, so
that a single sysroot, whichever order the libraries are built and
installed in, works for both. The effect of having the wrong version
installed is that you end up with a miscompiled sparc64 libstdc++
which fails glibc's configure tests for the C++ compiler.
This patch moves the header from sysdeps/unix/sysv/linux/sparc to
separate copies of the same file for sparc32 and sparc64, to ensure it
comes before ldbl-opt in the sysdeps directory ordering.
Tested with build-many-glibcs.py for sparc64-linux-gnu and
sparcv9-linux-gnu.

Fix position of tests-unsupported definition in assert/Makefile.
tests-unsupported has to be defined before the inclusion of Rules in a
subdirectory Makefile; otherwise it is ineffective. This patch fixes
the ordering in assert/Makefile, where a recent test addition put
tests-unsupported too late (resulting in build failures when the C++
compiler was missing or broken, and thereby showing up the unrelated
bug 21987).
Incidentally, I don't see why these tests depend on
$(have-cxx-thread_local) rather than just a working C++ compiler.
Tested in such a configuration (broken compiler/libstdc++) with

This test is using various objects from the build of libc. Some of
those objects contain references to __assert_fail. Because those
references are hidden, they cannot refer to __assert_fail from
libc.so. Given the tests using internal objects those symbols in
libc.a can't safely be made hidden, so this patch reverts the problem
commit until any alternative approach that doesn't break the build can
be found.

Remove SPARC sqrt wrappers (bug 21973).
This patch removes the SPARC-specific wrappers for sqrt and sqrtf.
These wrappers, by adding architecture-specific uses of _LIB_VERSION
and __kernel_standard, unnecessarily complicate cleanups of libm error
handling. They also do not serve a useful optimization purpose. GCC
knows about sqrt as a built-in function, and can generate direct calls
to a hardware square root instruction, either on its own, in the
-fno-math-errno case, or together with an inline check for the
argument being negative and a call to the out-of-line sqrt function
for error handling only in that case (and has been able to do so for a
long time). Thus in practice the wrapper will only be called only in
the case of negative arguments, which is not a case it is useful to
optimize for.
The removal of the wrappers also uncovers, and fixes, an old bug.
32-bit SPARC libm used (checked with glibc 2.8 binaries) to have a
sqrtl compat symbol, version GLIBC_2.0, for old binaries when sqrtl
was an alias of sqrt (I don't have pre-glibc-2.4 binaries for SPARC to
hand to check for the sqrtl symbol in those). This disappeared,
probably with:

Add sparc optimized sqrt{,f}.
Removing the wrappers brings back the generic ldbl-opt logic for
creating such compat symbols, and so restores the compat symbol that
should be there. This could of course also be fixed in the wrappers -
but as noted above, the wrappers are optimizing a case it's not useful
to optimize, so the bug of the missing compat symbol serves to
illustrate the risks involved with the extra complexity of
architecture-specific function versions where not needed.
Tested with build-many-glibcs.py.

Obsolete matherr, _LIB_VERSION, libieee.a.
This patch obsoletes support for SVID libm error handling (the system
where a user-defined function matherr is called on a libm function
error; only enabled if you also set _LIB_VERSION = _SVID_ or
_LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global
variable to control libm error handling. matherr and _LIB_VERSION are
made into compat symbols, not supported for new ports or for static
linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_,
so disabling errno setting for some functions) is also removed, and
all the related definitions are removed from math.h.
The manual already recommends against using matherr, and it's already
not supported for _Float128 functions (those use new wrappers that
don't support matherr, only errno) - this patch means that it becomes
possible to e.g. add sinf32 as an alias to sinf without that resulting
in undesired matherr support in sinf32 for existing glibc ports.
matherr support is not part of any standard supported by glibc (it was
removed in XPG4).
Because matherr is a function to be defined by the user, of course
user programs defining such a function will still continue to link; it
just quietly won't be used. If they try to write to the library's
copy of _LIB_VERSION to enable SVID error handling, however, they will
get a link error (but if they define their own _LIB_VERSION variable,
they won't).
I expect the most likely case of build failures from this patch to be
programs with unconditional cargo-culted uses of -lieee (based on a
notion of "I want IEEE floating point", not any actual requirement for
that library).
Ideally, the new-port-or-static-linking case would use the new
wrappers used for _Float128. This is not implemented in this patch,
because of the complication of architecture-specific (powerpc32 and
sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard
directly. Thus, the old wrappers and __kernel_standard are still
built unconditionally, and _LIB_VERSION still exists in static libm.
But when the old wrappers and __kernel_standard are built in the
non-compat case, _LIB_VERSION and matherr are defined as macros so
code to support those features isn't actually built into static libm
or new ports' shared libm after this patch.
I intend to move to the new wrappers for static libm and new ports in
followup patches. I believe the sqrt wrappers for powerpc32 and sparc
can reasonably be removed. GCC already optimizes the normal case of
sqrt by generating code that uses a hardware instruction and only
calls the sqrt function if the argument was negative (if
-fno-math-errno, of course, it just uses the hardware instruction
without any check for negative argument being needed). Thus those
wrappers will only actually get called in the case of negative
arguments, which is not a case it makes sense to optimize for. But
even without removing the powerpc32 and sparc wrappers it should still
be possible to move to the new wrappers for static libm and new ports,
just without having those dubious architecture-specific optimizations
in static libm.
Everything said about matherr equally applies to matherrf and matherrl
(IA64-specific, undocumented), except that the structure of IA64 libm
means it won't be converted to using the new wrappers (it doesn't use
the old ones either, but its own error-handling code instead).
As with other tests of compat symbols, I expect test-matherr and
test-matherr-2 to need to become appropriately conditional once we
have a system for disabling such tests for ports too new to have the
relevant symbols.

Do not use __builtin_types_compatible_p in C++ mode (bug 21930)
The logic to define isinf for float128 depends on the availability of
__builtin_types_compatible_p, which is only available in C mode,
however, the conditionals do not check for C or C++ mode. This lead to
an error in libstdc++ configure, as reported by bug 21930.
This patch adds a conditional for C mode in the definition of isinf for
float128. No definition is provided in C++ mode, since libstdc++
headers undefine isinf.
Tested for powerpc64le (glibc test suite and libstdc++-v3 configure).

Add math benchmark latency test
This patch further improves math function benchmarking by adding a latency
test in addition to throughput. This enables more accurate comparisons of
the
math functions. The latency test works by creating a dependency on the
previous
iteration: func_res = F (func_res * zero + input[i]). The multiply by zero
avoids changing the input.
It reports reciprocal throughput and latency in nanoseconds (depending on
the
timing header used) and max/min throughput in iterations per second:
"workload-spec2006.wrf": {

Fix sigval namespace (bug 21944).
XPG4.2 defines the siginfo_t type, but not union sigval or its
contents (which were added in the 1993 edition of POSIX.1), resulting
in namespace violations for sigval, sival_int and sival_ptr for
signal.h and sys/wait.h for that standard because those headers
incorrectly expose those names in that case.
This patch fixes this problem. The public type in this case is union
sigval, but various places in the headers use the sigval_t name for
it; direct uses of union sigval are already properly guarded or in
headers not in XPG4.2. Now, sigval_t, although not a standard name,
does seem to be widely used outside glibc. The approach taken by this
patch is to make installed headers use the name __sigval_t instead.
__sigval_t is then defined to either union sigval or union __sigval
(where union __sigval has __-prefixed member names as well), depending
on whether there are any namespace issues with the union sigval name
and its members. In the case where union __sigval is used, sigval_t
is not defined at all, to avoid the problem of sigval_t having a C++
mangled name that depends on feature test macros. sigval_t is still
defined by signal.h if __USE_MISC (reflecting the nonstandard nature
of that name).
Tested for x86_64.

Allow abort PLT references in libc.so for SH.
Given my patch
<https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00965.html> for the
ICEs building a glibc string function test for SH, the testsuite can
build completely for SH with GCC 7 and mainline. However, there is a
test failure that does not appear for GCC 6: check-localplt fails
because of an abort PLT reference in libc.so.
Given the lack of a trap insn pattern for SH, it seems unavoidable
that the compiler might sometimes generate abort calls, and such abort
calls (generated from __builtin_trap when there is no trap insn
pattern) will be unaffected by the normal mapping to __GI_abort for
calls within glibc. Thus, this patch allows (but does not require) an
abort PLT reference in libc.so for SH.
Tested for sh4-linux-gnu with build-many-glibcs.py (GCC 7, with my
patch applied).
* sysdeps/unix/sysv/linux/sh/localplt.data: Allow abort in
libc.so.

NSS: Replace exported NSS lookup functions with stubs [BZ #21962]
Commit 384ca551743318bd9c9e24a496d6397f2e3f2a49 from 2007 added this to
nss/XXX-lookup.c:
+#ifndef NO_COMPAT
+int
+internal_function attribute_compat_text_section
+DB_COMPAT_FCT (service_user **ni, const char *fct_name, void **fctp)
+{
+ return DB_LOOKUP_FCT (ni, fct_name, NULL, fctp);
+}
+#endif
That is, it adds a pseudo-compat function with an internal_function
attribute. The function it was supposed to replace did not have the
attribute:
extern int DB_LOOKUP_FCT (service_user **ni, const char *fct_name,
- void **fctp) internal_function;
+ const char *fct2_name, void **fctp)
+ internal_function;
This changed the calling convention on i386 for the following
functions in the public ABI:
__nss_passwd_lookup
__nss_group_lookup
__nss_hosts_lookup
This commit replaces the functions with always-failing stubs,
with true compat symbols. Due to a happy accident, the calling
convention of the stub is identical for the internal_function
and non-internal_function case on i386.
In addition, this commit auto-generates the __nss_*_lookup2
function declarations as part of <nsswitch.h>.

posix: Fix mmap for m68k and ia64 (BZ#21908)
Default semantic for mmap2 syscall is to take the offset in 4096-byte
units. However m68k and ia64 mmap2 implementation take in the
configured pageunit units and for both architecture it can be
different values.
This patch fixes the m68k runtime discover of mmap2 offset unit
and adds the ia64 definition to find it at runtime.
Checked the basic tst-mmap and tst-mmap-offset on m68k (the system
is configured with 4k, so current code is already passing on this
system) and a sanity check on x86_64-linux-gnu (which should not be
affected by this change). Sergei also states that ia64 loader now
work correctly with this change.

i386: Do not set internal_function
All calls to functions with the internal_function attribute
have been removed from assembler implementations, which means that
the definition of internal_function can be changed at the C level
without causing ABI issues with assembler code.
_dl_fixup still uses a regparm calling convention on i386, but this
is controlled through ARCH_FIXUP_ATTRIBUTE, not internal_function.

_dl_fini: Remove internal_function attribute
Assembler code passes the address of _dl_fini to __libc_start_main,
whose function pointer argument lacks the attribute. This means
that calls could use the wrong ABI. Fortunately, for zero-parameter
void-returning functions, internal_function does not change ABI
on i386 (the only architecture which uses internal_function), so
this inconsistency was harmless (which is why it had not been
noticed so far).

Locales: Use Unicode wise thousands separator
Many languages use small gap as thousands separator.
Thousands separator should not be a plain space, but a narrow space.
And additionally, it is not allowed to wrap line in the middle of the
number.
Locale data were created in a deep age of 8-bit encodings, so most of
them use space (incorrect: it allows wrapping the line in the middle
of the number), or NBSP (better, but typographically incorrect: space
between groups is too wide).
Now UNICODE is widely supported, so we should leave legacy characters
in favor of correct UNICODE character.
UNICODE has a dedicated character for this purpose:
NNBSP
U+202F NARROW NO-BREAK SPACE: a narrow form of a no-break space,
typically the width of a thin space or a mid space
The NNBSP exists since Unicode 3.0.
Use of NNBSP will prevent line wrapping in the midle of number and
improve readability of numbers.

powerpc: Restrict xssqrtqp operands to Vector Registers (bug 21941)
POWER ISA 3.0 introduces the xssqrtqp instructions, which expects
operands to be in Vector Registers (Altivec/VMX), even though this
instruction belongs to the Vector-Scalar Instruction Set.
In GCC's Extended Assembly for POWER, the 'wq' register constraint is
provided for use with IEEE 754 128-bit floating-point values. However,
this constraint does not limit the register allocation to Vector
Registers (Altivec/VMX) and could assign a Vector-Scalar Register (VSX)
to the operands of the instruction.
This patch changes the register constraint used in sqrtf128 from 'wq' to
'v', in order to request a Vector Register (Altivec/VMX) for use with
the xssqrtqp instruction.
Tested for powerpc64le and --with-cpu=power9.
[BZ #21941]
* sysdeps/powerpc/fpu/math_private.h (__ieee754_sqrtf128): Since
xssqrtqp requires operands to be in Vector Registers
(Altivec/VMX), replace the register constraint 'wq' with 'v'.
* sysdeps/powerpc/powerpc64le/power9/fpu/e_sqrtf128.c
(__ieee754_sqrtf128): Likewise.

[AArch64] Optimized memcmp.
This is an optimized memcmp for AArch64. This is a complete rewrite
using a different algorithm. The previous version split into cases
where both inputs were aligned, the inputs were mutually aligned and
unaligned using a byte loop. The new version combines all these cases,
while small inputs of less than 8 bytes are handled separately.
This allows the main code to be sped up using unaligned loads since
there are now at least 8 bytes to be compared. After the first 8 bytes,
align the first input. This ensures each iteration does at most one
unaligned access and mutually aligned inputs behave as aligned.
After the main loop, process the last 8 bytes using unaligned accesses.
This improves performance of (mutually) aligned cases by 25% and
unaligned by >500% (yes >6 times faster) on large inputs.
* sysdeps/aarch64/memcmp.S (memcmp):
Rewrite of optimized memcmp.

ld.so: Introduce struct dl_exception
This commit separates allocating and raising exceptions. This
simplifies catching and re-raising them because it is no longer
necessary to make a temporary, on-stack copy of the exception message.

__inet6_scopeid_pton: Remove attribute_hidden, internal_function
The hidden attribute was overridden by libc_hidden_proto on GNU/Linux.
It is incorrect because the function is used from nscd.
internal_function is not supposed to be used across DSO boundaries,
so this commit removes it (again, due to the use in nscd).

Fix stdlib/tst-strfmon_l.c test case to agree with the changes in Indian
monetary formatting
The test cases should expose non-standard grouping and the trailing
space after the currency sign. After the changes to the Indian
monetary formatting, the Indian formatting still shows the
non-standard grouping. To test the trailing space after the currency
sign I chose the hr_HR locale.

Remove enum __ptrace_flags along with the only constant it contains,
PTRACE_SEIZE_DEVEL, from Linux's sys/ptrace.h files.
This temporary development constant shouldn't have been added to

v3.1-rc1~308^2~28 as a temporary part of new experimental PTRACE_SEIZE
interface. Later, as PTRACE_SEIZE stabilized and lost its experimental
status, this flag was removed from Linux by commit v3.4-rc1~109^2~20.

bits/types.h defines a type __qaddr_t that is not used anywhere in
glibc. It doesn't appear to be widely used outside glibc either

definitions of this type, not uses), so it seems appropriate to remove
this type, which this patch does.

Fix uc_* namespace (bug 21457).
The standard members of ucontext_t, in all standard versions with that
type, are uc_link, uc_sigmask, uc_stack and uc_mcontext.
The uc_* namespace is mostly reserved for additions to the structure.
However, in XPG4.2, it's only reserved when <ucontext.h> is included,
not when <signal.h> is included, while <signal.h> is required to
define ucontext_t (but not allowed to make visible other symbols from
<ucontext.h>). Thus, nonstandard members should avoid uc_* names.
Some already do use __uc_*, but others don't; most architectures (all
except ia64, I think) have a member uc_flags and some have additional
members beyond that.
This patch makes nonstandard members have an __ prefix unless
__USE_MISC is defined. Members whose names indicate they are solely
padding / reserved for future use are renamed unconditionally to use
the __glibc_reserved1 naming convention.
This is part of the preparation for a revised version of the
mcontext_t / sigcontext patch to be able to eliminate all 13 of the
miscellaneous XFAILs in conform/Makefile, rather than only 11 of them
as at present (at least one further fix on top of this one will be
needed for that as well).
Tested for x86_64, and with build-many-glibcs.py.

aarch64: Optimized memcpy for Qualcomm Falkor processor
This is an optimized implementation of the memcpy routine that gives a
significant gain in performance for all sizes of copies on the
Qualcomm Falkor processor. A detailed rationale of the implementation
is written in a comment in the patch.
This implementation improves time for copies up to 128 bytes by up to
15% and for larger copies by up to 35% in the glibc
microbenchmark. The memcpy-random benchmark sees improvements in all
sizes in the range of 13%-18%.
Here are the full numbers extracted from the glibc microbenchmark
using the commands:

manual: Document getcontext uc_stack value on Linux [BZ #759]
As decribed in BZ#759, Linux getcontext implementation on Linux does
differs from other SysV system about the returned uc_stack. This is
true not only for i386, but for all the architecture I could actually
check (aarch64, arm, alpha, hppa, m68k, mips, mips64, mips64n32,
powerpc, powerpc64, powerpc64le, s390x, sh, sparc, sparc64, and x86).
And I think we should not change current behavior for some reasons:
1. POSIX 2008 removed this SySV interface for a good reason and changing
this behavior adds nothing for current portable code. POSIX 2001
specification does states that stack should be saved [1] and current
GLIBC code does in a arch-specific manner (inside the mcontext_t)
which allows the setcontext to work correctly.
2. Changing this behavior would potentially require compat symbols and
I see no gain in adding compat symbols for deprecated interfaces.
3. Also, for comment #2 in BZ#759, it is up to kernel do setup the contents
for ucontext_t and currently it does not provide the stack information
as well. Trying to change it is also another fix that does not worth
the possible gains.
Instead my proposal is to make it clear the current interface may differ
depending of the underlying operational system.
glibc documentation and close this bug as invalid.

Do not use __ptr_t.
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use
instead of void *. void * is a well-understood standard type for that
purpose and in a post-C89 context there is no need for a macro for it;
this patch changes those places to use void * directly instead.
Unlike __long_double_t, __ptr_t is widely used outside glibc (or at
least has many hits on codesearch.debian.net). I don't know how many
of those uses would break if sys/cdefs.h ceased to define the macro,
but there's enough risk that this patch leaves the definition and just
removes the uses within glibc; removal of the definition can be
considered separately if desired.
Tested for x86_64, and with build-many-glibcs.py.

i386: Add <startup.h> [BZ #21913]
On Linux/i386, there are 3 ways to make a system call:
1. call *%gs:SYSINFO_OFFSET. This requires TLS initialization.
2. call *_dl_sysinfo. This requires relocation of _dl_sysinfo.
3. int $0x80. This is slower than #2 and #3, but works everywhere.
When an object file is compiled with PIC, #1 is prefered since it is
faster than #3 and doesn't require relocation of _dl_sysinfo. For
dynamic executables, ld.so initializes TLS. However, for static
executables, before TLS is initialized by __libc_setup_tls, #3 should
be used for system calls.
This patch adds <startup.h> which defines _startup_fatal and defaults
it to __libc_fatal. It replaces __libc_fatal with _startup_fatal in
static executables where it is called before __libc_setup_tls is called.
This header file is included in all files containing functions which are
called before __libc_setup_tls is called. On Linux/i386, when PIE is
enabled by default, _startup_fatal is turned into ABORT_INSTRUCTION and
I386_USE_SYSENTER is defined to 0 so that "int $0x80" is used for system
calls before __libc_setup_tls is called.
Tested on i686 and x86-64. Without this patch, all statically-linked
tests will fail on i686 when the compiler defaults to -fPIE.
[BZ #21913]
* csu/libc-tls.c: Include <startup.h> first.

Don't use IFUNC resolver for longjmp or system in libpthread (bug 21041)
Unlike the vfork forwarder and like the fork forwarder as in bug 19861,
there won't be a problem when the compiler does not turn this into a tail
call.

posix: Set p{read,write}v2 to return ENOTSUP (BZ#21780)
Different than other architectures hppa-linux-gnu define different values
for ENOTSUP and EOPNOTSUPP, where the later is a Linux specific one.
This leads to tst-preadwritev{64}v2 tests failures:
$ ./testrun.sh misc/tst-preadvwritev2
error: tst-preadvwritev2-common.c:35: preadv2 failure did not set errno to
ENOTSUP (223)
error: 1 test failures
The straightforward fix is to return the POSIX defined ENOTSUP on all
p{read,write}v{64}v2 implementations instead of Linux specific one.
Checked on x86_64-linux-gnu and the tst-preadwritev{64}v2 on
hppa-linux-gnu (although due the installed kernel on my testing system
the pwritev{64}v2 with an invalid flag still fails due a known kernel
issue [1]).

Fix XPG4.2 bits/sigaction.h namespace (bug 21899).
For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and
SA_NODEFER should be defined in signal.h, but they are only defined
for other standards at present.
This patch fixes the various bits/sigaction.h headers accordingly.
All the fixes are essentially the same, except those for SPARC and
Tile.
For SPARC, the header (a) spuriously defined various nonstandard
macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some
standard macros as aliases of nonstandard ones instead of the other
way round. This patch fixes the SPARC header to handle these macros
the same way and with the same conditions as those for other
architectures, so the standard macros are the primary ones and the
other ones are defined only for __USE_MISC and are aliases of the
standard ones where applicable.
For Tile, the header spuriously defined the nonstandard macro
SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved
to __USE_MISC.
(Those nonstandard macros are in a reserved namespace, but it seems
desirable to be consistent between architectures as far as possible,
and so not define them in standard modes anywhere.)
Tested for x86_64, and with build-many-glibcs.py.

Consistently use uintN_t not u_intN_t everywhere.
This patch changes the remaining uses of the old nonstandard u_intN_t
types in glibc to use the C99 uintN_t instead, except for the
definitions of those typedefs and the tests of them in the c++-types
test. This follows the previous such fix for libm, and being
consistent in using uintN_t makes sense as a global cleanup.

Remove __long_double_t.
sys/cdefs.h has a macro __long_double_t used in two places in glibc.
long double is a standard part of C since C89; there is no need for
such an alias for it. This patch removes that macro and uses long
double directly everywhere. As an implementation-namespace,
undocumented symbol, it should not be considered part of the API for
users, and codesearch.debian.net shows no sign of it being used
outside glibc in a way that would break with this patch.
Tested for x86_64.

Since start.o may be compiled as PIC, we should check PIC instead of
SHARED. Also avoid dynamic relocation against main in static PIE since
_start is the entry point before the executable is relocated.

Consistently use uintN_t not u_intN_t in libm.
This patch changes libm code to make consistent use of C99 uintN_t
types instead of sometimes using those and sometimes using the older
nonstandard u_intN_t names. This makes sense as a cleanup in its own
right, and also facilitates merges to GCC's libquadmath (which gets
the types from stdint.h and so may not have u_intN_t available at
all).
Tested for x86_64, and with build-many-glibcs.py.

tst-tlsopt-powerpc as a shared lib
This makes the __tls_get_addr_opt test run as a shared library, and so
actually test that DTPMOD64/DTPREL64 pairs are processed by ld.so to
support the __tls_get_adfr_opt call stub fast return. After a
2017-01-24 patch (binutils f0158f4416) ld.bfd no longer emitted
unnecessary dynamic relocations against local thread variables,
instead setting up the __tls_index GOT entries for the call stub fast
return. This meant tst-tlsopt-powerpc passed but did not check ld.so
relocation support. After a 2017-07-16 patch (binutils 676ee2b5fa)
ld.bfd no longer set up the __tls_index GOT entries for the call stub
fast return, and tst-tlsopt-powerpc failed.
Compiling mod-tlsopt-powerpc.c with -DSHARED exposed a bug in
powerpc64/tls-macros.h, which defines a __TLS_GET_ADDR macro that
clashes with one defined in dl-tls.h. The tls-macros.h version is
only used in that file, so delete it and expand.
* sysdeps/powerpc/mod-tlsopt-powerpc.c: Extract from

Fix tgmath.h for __int128 (bug 21686).
When a tgmath.h macro is passed a double argument and an argument of
type __int128, it generates a call to a long double function (although
the result still gets converted to type double). __int128 is similar
enough to integer types that it should be handled consistently like
them, so always like double for these macros rather than sometimes
like double and sometimes like long double. This patch fixes the
logic accordingly and makes gen-tgmath-tests.py generate tests for
__int128.
Tested for x86_64 and x86.

Fix tgmath.h for bit-fields (bug 21685).
The tgmath.h macros produce errors for bit-field arguments, because
they apply sizeof and typeof to the arguments. This patch fixes them
to use unary + systematically before using sizeof or typeof on
arguments that might be bit-fields (note that __real__ of a bit-field
is still a bit-field for this purpose, since it's an lvalue).
gen-tgmath-tests.py is extended to add tests for this case.
Tested for x86_64.
