  update-linux-headers.sh: Don't hard code list of architectures

Rather than hardcoding the list of architectures in the kernel
header update script, just import headers for every architecture
which supports KVM (with a blacklist exception for ia64 which
has KVM headers but is dead). This reduces the number of QEMU
files which need to be updated to add support for a new KVM
architecture.

Move the init of the irqchip_inject_ioctl field of KVMState out of
kvm_irqchip_create() and into kvm_init(), so that kvm_set_irq()
can be used even when no irqchip is created (for architectures
that support async interrupt notification even without an in
kernel irqchip).

  memory: Flush coalesced MMIO on selected region access

Instead of flushing pending coalesced MMIO requests on every vmexit,
this provides a mechanism to selectively flush when memory regions
related to the coalesced one are accessed. This first of all includes
the coalesced region itself but can also applied to other regions, e.g.
of the same device, by calling memory_region_set_flush_coalesced.

  memory: Use transaction_begin/commit also for single-step operations

Wrap also simple operations consisting only of a single step with
memory_region_transaction_begin/commit. This allows to perform
additional steps like coalesced MMIO flushing from a single place.

This requires dropping some micro-optimizations: The skipping of
topology updates after updating disabled or unregistered regions.

  qxl: Ignore set_client_capabilities pre/post migrate

The recent introduction of set_client_capabilities has broken
(seamless) migration by trying to call qxl_send_events pre (seamless
incoming) and post (*) migration, triggering the following assert:
qxl_send_events: Assertion `qemu_spice_display_is_running(&d->ssd)' failed.

The solution is easy, pre migration the guest will have already received
the client caps on the migration source side, and post migration there no
longer is a guest, so we can simply ignore the set_client_capabilities call
in both those scenarios.

*) Post migration, so not fatal for to the migration itself, but still a crash

  ahci: properly reset PxCMD on HBA reset

While testing q35, I found that windows 7 (specifically, windows 7 ultimate
with sp1 x64), wouldn't install because it can't find the cdrom or disk drive.
The failure message is: 'A required cd/dvd device driver is missing. If you
have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.'
This can also be reproduced on piix by adding an ahci controller, and
observing that windows 7 does not see any devices behind it.

The problem is that when windows issues a HBA reset, qemu does not reset the
individual ports' PxCMD register. Windows 7 then reads back the PxCMD register
and presumably assumes that the ahci controller has already been initialized.
Windows then never sets up the PxIE register to enable interrupts, and thus it
never gets irqs back when it sends ata device inquiry commands.

This change brings qemu into ahci 1.3 specification compliance.

Section 10.4.3 HBA Reset:

"
When GHC.HR is set to '1', GHC.AE, GHC.IE, the IS register, and all port
register fields (except PxFB/PxFBU/PxCLB/PxCLBU) that are not HwInit in the
HBA's register memory space are reset.
"

I've also re-tested Fedora 16 and 17 to verify that they continue to work with
this change.

  hw/qxl: support client monitor configuration via device

Until now we used only the agent to change the monitor count and each
monitor resolution. This patch introduces the qemu part of using the
device as the mediator instead of the agent via virtio-serial.

Spice (>=0.11.5) calls the new QXLInterface::client_monitors_config,
which returns wether the interrupt is enabled, and if so and given a non
NULL monitors config will
generate an interrupt QXL_INTERRUPT_CLIENT_MONITORS_CONFIG with crc
checksum for the guest to verify a second call hasn't interfered.

The maximal number of monitors is limited on the QXLRom to 64.

  slirp: Implement TFTP Blocksize option

This option is described in RFC 1783. As this is only an optional field,
we may ignore it in some situations and handle it in some others.

However, MS Windows 2003 PXE boot client requests a block size of the MTU
(most of the times 1472 bytes), and doesn't work if the option is not
acknowledged (with whatever value).

According to the RFC 1783, we cannot acknowledge the option with a bigger
value than the requested one.

As current implementation is using 512 bytes by block, accept the option
with a value of 512 if the option was specified, and don't acknowledge it
if it is not present or less than 512 bytes.

  net: notify iothread after flushing queue

virtio-net has code to flush the queue and notify the iothread
whenever new receive buffers are added by the guest.  That is
fine, and indeed we need to do the same in all other drivers.
However, notifying the iothread should be work for the network
subsystem.  And since we are at it we can add a little smartness:
if some of the queued packets already could not be delivered,
there is no need to notify the iothread.

  eepro100: Fix network hang when rx buffers run out

This is reported by QA. When installing os with pxe, after the initial
kernel and initrd are loaded, the procedure tries to copy files from install
server to local harddisk, the network becomes stall because of running out of
receive descriptor.

[Whitespace fixes and removed qemu_notify_event() because Paolo's
earlier net patches have moved it into qemu_flush_queued_packets().

Additional info:

I can reproduce the network hang with a tap device doing a iPXE HTTP
boot as follows:

  $ qemu -enable-kvm -m 1024 \
    -netdev tap,id=netdev0,script=no,downscript=no \
    -device i82559er,netdev=netdev0,romfile=80861209.rom \
    -drive if=virtio,cache=none,file=test.img
  iPXE> ifopen net0
  iPXE> config # set static network configuration
  iPXE> kernel 
http://mirror.bytemark.co.uk/fedora/linux/releases/17/Fedora/x86_64/os/images/pxeboot/vmlinuz

I needed a vanilla iPXE ROM to get to the iPXE prompt.  I think the boot
prompt has been disabled in the ROMs that ship with QEMU to reduce boot
time.

During the vmlinuz HTTP download there is a network hang.  hw/eepro100.c
has reached the end of the rx descriptor list.  When the iPXE driver
replenishes the rx descriptor list we don't kick the QEMU net subsystem
and event loop, thereby leaving the tap netdev without its file
descriptor in select(2).

893379efd0e1b84ceb0c42a713293f3dbd27b1bd ("net: disable receiving if
client returns zero") only added the logic to qemu_deliver_packet() and
not qemu_deliver_packet_iov().

The receive_disabled flag should be automatically set when .receive(),
.receive_raw(), or .receive_iov() return 0.  No further packets will be
delivered to the NetClient until the receive_disabled flag is cleared
again by calling qemu_flush_queued_packets().

Typically the NetClient will wait until its file descriptor becomes
writable and then invoke qemu_flush_queued_packets() to resume
transmission.

  net: do not report queued packets as sent

Net send functions have a return value where 0 means the packet has not
been sent and will be queued.  A non-zero value means the packet was
sent or an error caused the packet to be dropped.

This patch fixes two instances where packets are queued but we return
their size.  This causes callers to believe the packets were sent.  When
the caller uses the async send interface this creates a real problem
because the callback will be invoked for a packet that the caller
believed to be already sent.  This bug can cause double-frees in the
caller.

  net: fix usbnet_receive() packet drops

The USB network interface has a single buffer which the guest reads
from.  This patch prevents multiple calls to usbnet_receive() from
clobbering the input buffer.  Instead we queue packets until buffer
space becomes available again.

This is inspired by virtio-net and e1000 rxbuf handling.

  net: broadcast hub packets if at least one port can receive

In commit 60c07d933c66c4b30a83b7ccbc8a0cb3df1b2d0e ("net: fix
qemu_can_send_packet logic") the "VLAN" broadcast behavior was changed
to queue packets if any net client cannot receive.  It turns out that
this was not actually the right fix and just hides the real bug that
hw/usb/dev-network.c:usbnet_receive() clobbers its receive buffer when
called multiple times in a row.  The commit also introduced a new bug
that "VLAN" packets would not be sent if one of multiple net clients was
down.

The hw/usb/dev-network.c bug has since been fixed, so this patch reverts
broadcast behavior to send packets as long as one net client can
receive.  Packets simply get queued for the net clients that are
temporarily unable to receive.

The net/socket.c net client is not truly asynchronous.  This patch
borrows the qemu_set_fd_handler2() code from net/tap.c as the basis for
proper asynchronous send/receive.

Only read packets from the socket when the peer is able to receive.
This avoids needless queuing.

Later patches implement asynchronous send.

  net: EAGAIN handling for net/socket.c TCP

Replace spinning send_all() with a proper non-blocking send.  When the
socket write buffer limit is reached, we should stop trying to send and
wait for the socket to become writable again.

Non-blocking TCP sockets can return in two different ways when the write
buffer limit is reached:

1. ret = -1 and errno = EAGAIN/EWOULDBLOCK.  No data has been written.

2. ret < total_size.  Short write, only part of the message was
   transmitted.

Handle both cases and keep track of how many bytes have been written in
s->send_index.  (This includes the 'length' header before the actual
payload buffer.)

  qemu-char: BUGFIX, don't call FD_ISSET with negative fd

tcp_chr_connect(), unlike for example udp_chr_update_read_handler() does
not check if the fd it is using is valid (>= 0) before passing it to
qemu_set_fd_handler2().  If using e.g. a TCP serial port, which is not
initially connected, this can result in -1 being passed to FD_ISSET, which
has undefined behaviour.  On x86 it seems to harmlessly return 0, but on
PowerPC, it causes a fortify buffer overflow error to be thrown.

This patch fixes this by putting an extra test in tcp_chr_connect(), and
also adds an assert qemu_set_fd_handler2() to catch other such errors on
all platforms, rather than just some.

  cpu_physical_memory_write_rom() needs to do TB invalidates

cpu_physical_memory_write_rom(), despite the name, can also be used to
write images into RAM - and will often be used that way if the machine
uses load_image_targphys() into RAM addresses.

However, cpu_physical_memory_write_rom(), unlike cpu_physical_memory_rw()
doesn't invalidate any cached TBs which might be affected by the region
written.

This was breaking reset (under full emu) on the pseries machine - we loaded
our firmware image into RAM, and while executing it rewrite the code at
the entry point (correctly causing a TB invalidate/refresh).  When we
reset the firmware image was reloaded, but the TB from the rewrite was
still active and caused us to get an illegal instruction trap.

This patch fixes the bug by duplicating the tb invalidate code from
cpu_physical_memory_rw() in cpu_physical_memory_write_rom().
