    - 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

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

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.

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.

Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This is the long overdue conversion of sparc64 over to
the generic IRQ layer.

The kernel image is slightly larger, but the BSS is ~60K
smaller due to the reduced size of struct ino_bucket.

A lot of IRQ implementation details, including ino_bucket,
were moved out of asm-sparc64/irq.h and are now private to
arch/sparc64/kernel/irq.c, and most of the code in irq.c
totally disappeared.

One thing that's different at the moment is IRQ distribution,
we do it at enable_irq() time.  If the cpu mask is ALL then
we round-robin using a global rotating cpu counter, else
we pick the first cpu in the mask to support single cpu
targetting.  This is similar to what powerpc's XICS IRQ
support code does.

This works fine on my UP SB1000, and the SMP build goes
fine and runs on that machine, but lots of testing on
different setups is needed.
