commit 86ecc3fc9aa88091ac77ec35688d08634567d169
Author: Justus Winter <address@hidden>
Date: Tue Aug 29 23:35:55 2017 +0200
Traverse translator hierarchies using the fsys protocol.
Previously, we used the fs protocol to traverse the translator
hierarchies. This, however, is conceptually flawed, because
translators are bound to nodes, and a node can have zero or more links
in the file system. Therefore, the previous method of returning a
list of paths to the client and expecting them to be able to follow
these to reach the child translators was always unreliable.
Fix this by using the fsys protocol to traverse the hierarchy, and
returning the control ports of all children. This is more robust, and
also conceptually cleaner, because the fsys protocol is about
translator linkage, hence this is the point to implement traversal.
Also move the get source routine over. A per-node source really
does not fit the reality of most translators, while a per-translator
source makes sense in many cases.
* hurd/fs.defs (file_get_children): Drop routine.
(file_get_source): Likewise.
* hurd/fsys.defs (fsys_get_children): New routine.
(fsys_get_source): Likewise.

return list of control ports.

Likewise.

known.
(mtab_populate): Limit depth of recursion, adapt to traversing over
the control ports, simplify.
(open_hook): Remove scary comment, it is not applicable anymore
because we no longer dir_lookup child translators.
commit e08859424e01697fe556e277283e8e1905327ce7
Author: Justus Winter <address@hidden>
Date: Tue Aug 22 13:07:54 2017 +0200
libfshelp: Use node instead of name as key.
Previously, libfshelp used the name of an translator as key in the
hash table. This however is flawed, because a translator is bound to
a node, and a node can have zero or more links in the file system.
Use the nodes address (or rather, the address of the transbox embedded
in the node) as key instead.
* libfshelp/fshelp.h (fshelp_set_active_translator): Instead of the
control port, hand the whole transbox to the function.
* libfshelp/translator-list.c (struct translator): New field 'locp'.
(hash): Hash pointer.
(compare): Compare pointer.
(translator_ihash): Use an location pointer.
(fshelp_set_active_translator): Use the address of the transbox as key.
(fshelp_remove_active_translator): Remove using the location pointer.
* libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Fix callsite.
* libdiskfs/file-set-trans.c (diskfs_S_file_set_translator): Likewise.
* libnetfs/dir-lookup.c (netfs_S_dir_lookup): Likewise.
* libnetfs/file-set-translator.c (netfs_S_file_set_translator):
Likewise.

Fix active translator registration.
* libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Unconditionally
register translators. Previously, we missed translators because
'transbox.active' is not in fact reset if the translator dies.
* libnetfs/dir-lookup.c (netfs_S_dir_lookup): Likewise.
