Hi,
I was doing some testing and noticed that when the audit system was disabled,
I was still getting messages about the loginuid being set. The following patch
makes audit_set_loginuid look at in_syscall to determine if it should create
an audit event. The loginuid will continue to be set as long as there is a context.

When an audit event involves changes to a directory entry, include
a PATH record for the directory itself. A few other notable changes:
- fixed audit_inode_child() hooks in fsnotify_move()
- removed unused flags arg from audit_inode()
- added audit log routines for logging a portion of a string
Here's some sample output.

Clear AUDIT_FILTER_PREPEND flag after adding rule to list. This
fixes three problems when a rule is added with the -A syntax:
- auditctl displays filter list as "(null)"
- the rule cannot be removed using -d
- a duplicate rule can be added with -a

In this implementation, audit registers inotify watches on the parent
directories of paths specified in audit rules. When audit's inotify
event handler is called, it updates any affected rules based on the
filesystem event. If the parent directory is renamed, removed, or its
filesystem is unmounted, audit removes all rules referencing that
inotify watch.
To keep things simple, this implementation limits location-based
auditing to the directory entries in an existing directory. Given
a path-based rule for /foo/bar/passwd, the following table applies:
passwd modified -- audit event logged
passwd replaced -- audit event logged, rules list updated
bar renamed -- rule removed
foo renamed -- untracked, meaning that the rule now applies to
the new location
Audit users typically want to have many rules referencing filesystem
objects, which can significantly impact filtering performance. This
patch also adds an inode-number-based rule hash to mitigate this
situation.
The patch is relative to the audit git tree:
http://kernel.org/git/?p=linux/kernel/git/viro/audit-current.git;a=summary
and uses the inotify kernel API:

This patch adds audit support to POSIX message queues. It applies cleanly to
the lspp.b15 branch of Al Viro's git tree. There are new auxiliary data
structures, and collection and emission routines in kernel/auditsc.c. New hooks
in ipc/mqueue.c collect arguments from the syscalls.
I tested the patch by building the examples from the POSIX MQ library tarball.
Build them -lrt, not against the old MQ library in the tarball. Here's the URL:
http://www.geocities.com/wronski12/posix_ipc/libmqueue-4.41.tar.gz
Do auditctl -a exit,always -S for mq_open, mq_timedsend, mq_timedreceive,
mq_notify, mq_getsetattr. mq_unlink has no new hooks. Please see the
corresponding userspace patch to get correct output from auditd for the new
record types.

The following patch addresses most of the issues with the IPC_SET_PERM
records as described in:
https://www.redhat.com/archives/linux-audit/2006-May/msg00010.html
and addresses the comments I received on the record field names.
To summarize, I made the following changes:
1. Changed sys_msgctl() and semctl_down() so that an IPC_SET_PERM
record is emitted in the failure case as well as the success case.
This matches the behavior in sys_shmctl(). I could simplify the
code in sys_msgctl() and semctl_down() slightly but it would mean
that in some error cases we could get an IPC_SET_PERM record
without an IPC record and that seemed odd.
2. No change to the IPC record type, given no feedback on the backward
compatibility question.
3. Removed the qbytes field from the IPC record. It wasn't being
set and when audit_ipc_obj() is called from ipcperms(), the
information isn't available. If we want the information in the IPC
record, more extensive changes will be necessary. Since it only
applies to message queues and it isn't really permission related, it
doesn't seem worth it.
4. Removed the obj field from the IPC_SET_PERM record. This means that
the kern_ipc_perm argument is no longer needed.
5. Removed the spaces and renamed the IPC_SET_PERM field names. Replaced iuid and
igid fields with ouid and ogid in the IPC record.
I tested this with the lspp.22 kernel on an x86_64 box. I believe it
applies cleanly on the latest kernel.

Just a few minor proposed updates. Only the last one will
actually affect behavior. The rest are just misleading
code.
Several AUDIT_SET functions return 'old' value, but only
return value <0 is checked for. So just return 0.
propagate audit_set_rate_limit and audit_set_backlog_limit
error values
In audit_buffer_free, the audit_freelist_count was being
incremented even when we discard the return buffer, so
audit_freelist_count can end up wrong. This could cause
the actual freelist to shrink over time, eventually
threatening to degrate audit performance.

We should not send a pile of replies while holding audit_netlink_mutex
since we hold the same mutex when we receive commands. As the result,
we can get blocked while sending and sit there holding the mutex while
auditctl is unable to send the next command and get around to receiving
what we'd sent.
Solution: create skb and put them into a queue instead of sending;
once we are done, send what we've got on the list. The former can
be done synchronously while we are handling AUDIT_LIST or AUDIT_LIST_RULES;
we are holding audit_netlink_mutex at that point. The latter is done
asynchronously and without messing with audit_netlink_mutex.

Add inotify_init_watch() so caller can use inotify_watch refcounts
before calling inotify_add_watch().
Add inotify_find_watch() to find an existing watch for an (ih,inode)
pair. This is similar to inotify_find_update_watch(), but does not
update the watch's mask if one is found.
Add inotify_rm_watch() to remove a watch via the watch pointer instead
of the watch descriptor.

The following series of patches introduces a kernel API for inotify,
making it possible for kernel modules to benefit from inotify's
mechanism for watching inodes. With these patches, inotify will
maintain for each caller a list of watches (via an embedded struct
inotify_watch), where each inotify_watch is associated with a
corresponding struct inode. The caller registers an event handler and
specifies for which filesystem events their event handler should be
called per inotify_watch.

Historically plat_mem_setup did the entire platform initialization. This
was rather impractical because it meant plat_mem_setup had to get away
without any kind of memory allocator. To keep old code from breaking
plat_setup was just renamed to plat_setup and a second platform
initialization hook for anything else was introduced.
