Peter Zijlstra 24ec839c43 [PATCH] tty: ->signal->tty locking
Fix the locking of signal->tty.

Use ->sighand->siglock to protect ->signal->tty; this lock is already used
by most other members of ->signal/->sighand.  And unless we are 'current'
or the tasklist_lock is held we need ->siglock to access ->signal anyway.

(NOTE: sys_unshare() is broken wrt ->sighand locking rules)

Note that tty_mutex is held over tty destruction, so while holding
tty_mutex any tty pointer remains valid.  Otherwise the lifetime of ttys
are governed by their open file handles.  This leaves some holes for tty
access from signal->tty (or any other non file related tty access).

It solves the tty SLAB scribbles we were seeing.

(NOTE: the change from group_send_sig_info to __group_send_sig_info needs to
       be examined by someone familiar with the security framework, I think
       it is safe given the SEND_SIG_PRIV from other __group_send_sig_info
       invocations)

Amy Griffis 5adc8a6adc [PATCH] add rule filterkey
Add support for a rule key, which can be used to tie audit records to audit
rules.  This is useful when a watched file is accessed through a link or
symlink, as well as for general audit log analysis.

Because this patch uses a string key instead of an integer key, there is a bit
of extra overhead to do the kstrdup() when a rule fires.  However, we're also
allocating memory for the audit record buffer, so it's probably not that
significant.  I went ahead with a string key because it seems more
user-friendly.

Note that the user must ensure that filterkeys are unique.  The kernel only
checks for duplicate rules.

    - 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.

Amy Griffis f368c07d72 [PATCH] audit: path-based rules
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:

George C. Wilson 20ca73bc79 [PATCH] Audit of POSIX Message Queue Syscalls v.2
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.

Linda Knippers ac03221a4f [PATCH] update of IPC audit record cleanup
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.

Steve Grubb 073115d6b2 [PATCH] Rework of IPC auditing
1) The audit_ipc_perms() function has been split into two different
functions:
        - audit_ipc_obj()
        - audit_ipc_set_perm()

There's a key shift here...  The audit_ipc_obj() collects the uid, gid,
mode, and SElinux context label of the current ipc object.  This
audit_ipc_obj() hook is now found in several places.  Most notably, it
is hooked in ipcperms(), which is called in various places around the
ipc code permforming a MAC check.  Additionally there are several places
where *checkid() is used to validate that an operation is being
performed on a valid object while not necessarily having a nearby
ipcperms() call.  In these locations, audit_ipc_obj() is called to
ensure that the information is captured by the audit system.

The audit_set_new_perm() function is called any time the permissions on
the ipc object changes.  In this case, the NEW permissions are recorded
(and note that an audit_ipc_obj() call exists just a few lines before
each instance).

2) Support for an AUDIT_IPC_SET_PERM audit message type.  This allows
for separate auxiliary audit records for normal operations on an IPC
object and permissions changes.  Note that the same struct
audit_aux_data_ipcctl is used and populated, however there are separate
audit_log_format statements based on the type of the message.  Finally,
the AUDIT_IPC block of code in audit_free_aux() was extended to handle
aux messages of this new type.  No more mem leaks I hope ;-)

now we can do that - all callers are process-synchronous and do not hold
any locks.

Al Viro 45d9bb0e37 [PATCH] deal with deadlocks in audit_free()
Don't assume that audit_log_exit() et.al. are called for the context of
current; pass task explictly.

Ingo Molnar 4023e02080 [PATCH] simplify audit_free() locking
Simplify audit_free()'s locking: no need to lock a task that we are tearing
down.  [the extra locking also caused false positives in the lock
validator]

Amy Griffis 93315ed6dd [PATCH] audit string fields interface + consumer
Updated patch to dynamically allocate audit rule fields in kernel's
internal representation.  Added unlikely() calls for testing memory
allocation result.

Dustin Kirkland 7306a0b9b3 [PATCH] Miscellaneous bug and warning fixes
This patch fixes a couple of bugs revealed in new features recently
added to -mm1:
* fixes warnings due to inconsistent use of const struct inode *inode
* fixes bug that prevent a kernel from booting with audit on, and SELinux off
  due to a missing function in security/dummy.c
* fixes a bug that throws spurious audit_panic() messages due to a missing
  return just before an error_path label
* some reasonable house cleaning in audit_ipc_context(),
  audit_inode_context(), and audit_log_task_context()
