content.
commit 122224d32894a8465a09561fc0a5220f5bb9c2c7
Author: Justus Winter <address@hidden>
Date: Thu May 22 20:25:22 2014 +0200
Implement /proc/slabinfo
Add a node 'slabinfo' to the root directory that contains information
about the slab allocator used in GNU Mach.
The formatting code has been taken from Richard Braun's standalone
client available here:
git://darnassus.sceen.net/rbraun/slabinfo.git
* rootdir.c (rootdir_gc_slabinfo): New function.
(rootdir_entries): Add node 'slabinfo'.

Author: Richard Braun <address@hidden>
Date: Fri Oct 4 20:27:45 2013 +0200
Fix mtab translator leak
The node structure for the `mounts' entry is created and destroyed on
each access, despite the fact a translator is activated on it. Fix the
issue by caching it.
* rootdir.c (rootdir_mounts_node): New variable.
(rootdir_mounts_node_lock): Likewise.
(rootdir_mounts_make_node): New function.

(rootdir_mounts_get_translator): New function.
(rootdir_mounts_exists): New function.
(rootdir_translator_make_node): Likewise.
(rootdir_entries): Add "mounts" node.
commit 690beb4d6679c66f45d09883408cb860337e31c2
Author: Justus Winter <address@hidden>
Date: Mon Aug 5 12:11:30 2013 +0200
Make start_code and end_code available in /proc/*/stat
This makes killall5 actually kill any processes not marked as
important.
* process.c (process_file_gc_stat): Fix {start,end}_code.
commit 883e9a3bcbd0de620272c79b6a081b42b0832ef4
Author: Justus Winter <address@hidden>
Date: Fri Jun 28 18:37:45 2013 +0200
procfs: provide a more meaningful response to fsys_get_options
Implement our own netfs_append_args function that provides the
appropriate command line flags if the current values differ from the
default values.
* procfs/main.c (netfs_append_args): New function.
commit 2f13ab11aa71a2b8fb6e045a9ff81b7b2252cbe0
Author: Justus Winter <address@hidden>
Date: Fri Jun 28 18:37:44 2013 +0200
procfs: define macros for the default argument values
Define a macro for the default value of each command line
parameter. This allows one to generate a minimal response to
fsys_get_options requests.
* procfs/main.c: New macro definitions for default values.
commit 2baaf773daa797048ea96573fa01786d129f00fb
Author: Justus Winter <address@hidden>
Date: Fri Jun 28 18:37:43 2013 +0200
procfs: handle the --update parameter
Split the argument handling into a common part and one for
fsys_update_options. Handle the --update parameter; for procfs this is
a no-op.
* procfs/main.c (common_options): New variable.
(runtime_argp_parser): Handle --update.
(startup_argp): New variable.
(netfs_runtime_argp_): New variable.
commit eda9e61107ed34a5f7a566fe6835a48c48aec1d3
Author: Justus Winter <address@hidden>
Date: Mon Aug 26 19:32:24 2013 +0200
Fix argument parsing
The switch statement was missing the default case returning
ARGP_ERR_UNKNOWN. This patch adds that.
* main.c (argp_parser): Add default case.
commit fc7055f2461fa92bc17d67f02058399dca5736ae
Author: Justus Winter <address@hidden>
Date: Mon Jul 22 17:54:38 2013 +0200
rootdir.c: Fix declaration of rootdir_fakeself_exists.
* rootdir.c (rootdir_fakeself_exists): Use the correct arguments for
this kind of function.
commit 7802531da03626cfded497239e29a8ec2e4a3285
Author: Justus Winter <address@hidden>
Date: Mon Jul 22 17:54:37 2013 +0200
rootdir.c: Fix compiler warning

Author: Justus Winter <address@hidden>
Date: Mon Jul 22 17:54:36 2013 +0200
Makefile: add -lpthread
* Makefile (LIBS): Link with libpthread.
commit 92132dda0f13b2f4e82048797acfb7c34da2f53f
Author: Samuel Thibault <address@hidden>
Date: Mon Jul 22 22:57:38 2013 +0200

commit 890f987c15029d7e29f7deea0bba0b8d4ecaeaeb
Author: Justus Winter <address@hidden>
Date: Tue Jul 16 10:51:22 2013 +0200
Add the necessary infrastructure to serve passive translators
* netfs.c (netfs_get_translator): New function.
* procfs.c (procfs_get_translator): Likewise.
* procfs.h (struct procfs_node_ops): New field get_translator.
(procfs_get_translator): New function declaration.
commit 641249f6b143c4e22825e18e0dbe22bb04d21138
Author: Justus Winter <address@hidden>
Date: Tue Jul 16 10:51:21 2013 +0200
Fix default file ownership
Formerly all nodes were created so that they were owned by root:root
by default. This causes problems if the procfs translator is running
as unprivileged user and serves passive translator records, because
the file ownership is being used as credentials for starting
translators. This obviously fails if the procfs translator is not root
but is trying to acquire credentials including uid/gid 0.
Fix this by using the uid/gid of the procfs translator by default.
procfs.c (procfs_make_node): Fix default node ownership.
commit b1a3f96a8139c5ed3aac7b8a77b06ba4c0a877c7
Author: Justus Winter <address@hidden>
Date: Tue Jul 16 10:51:20 2013 +0200
Fix procfs_node_chmod
Formerly only the mode_t bits cut out by S_IFMT were preserved, but
this does not include S_IPTRANS. Fix this by preserving everything but
the permission bits.
* procfs.c (procfs_node_chmod): Fix bitmask.
commit 669dadfa07a5e63db8d9e572603872be88db52a3
Author: Justus Winter <address@hidden>
Date: Sat Jul 20 17:47:05 2013 +0200
procfs: Ignore arguments for compatibility with Linux' procfs.
Ignore the --nodev, --noexec and --nosuid arguments.
* procfs/main.c (argp_parser): Ignore some arguments for compatibility.
commit fd1f64a2e9e794a0184238bf3a0c4b7f5c6f963c
Author: Justus Winter <address@hidden>
Date: Sat Jun 29 22:14:13 2013 +0200
procfs: enable fsys_set_options
Make procfs translators handle fsys_set_options requests by pointing
netfs_runtime_argp to our argp struct.
* procfs/main.c (netfs_runtime_argp): New variable.
commit ea6ea2f554bc81b856d5286c23c2b4c8ba303fb9
Author: Justus Winter <address@hidden>
Date: Sat Jun 29 22:13:16 2013 +0200
procfs: keep old config values if the parsing fails
Previously if strtol failed the previous configuration value would get
overwritten. Prevent this by storing the result in a temporary
variable and update the configuration if the argument was parsed
correctly and passed the sanity checks.
* procfs/main.c (argp_parser): Keep old configuration in case a
malformed value is encountered.
commit 26b18d8e7d8bb5f1bf9ae20e40e8b291db3cebd6
Author: Samuel Thibault <address@hidden>
Date: Sat Jun 29 22:10:09 2013 +0200
procfs: fix the error handling in argp_parser
Do not exit using error (1, ..) but gracefully handle the error using
argp_error. Also fix a typo ("the a user") while touching these lines.
* procfs/main.c (argp_parser): Proper error handling.
(argp_parser): Fix typo.

PID stat/status: show only the file name of processes
The Linux /proc fs shows only the file name of processes in the
`stat' and `status' files of every process directory, so adapt also
procfs to show process file names.
Add a new `args_filename` function, much similar to GNU's `basename'
but returning the original string also when the resulting file name
is an empty string.
* process.c (args_filename): New function.
(process_file_gc_stat): Wrap the `proc_stat_args' result with
`args_filename'.
(process_file_gc_status): Likewise.
