b593d384ef [AUDIT] create context if auditing was ever enabled
Disabling audit at runtime by auditctl doesn't mean that we can
stop allocating contexts for new processes; we don't want to miss them
when that sucker is reenabled.

(based on work from Al Viro in the RHEL kernel series)

1a6b9f2317 [AUDIT] make audit=0 really stop audit messages
Some audit messages (namely configuration changes) are still emitted even if
the audit subsystem has been explicitly disabled.  This patch turns those
messages off as well.

de6bbd1d30 [AUDIT] break large execve argument logging into smaller messages
execve arguments can be quite large.  There is no limit on the number of
arguments and a 4G limit on the size of an argument.

this patch prints those aruguments in bite sized pieces.  a userspace size
limitation of 8k was discovered so this keeps messages around 7.5k

single arguments larger than 7.5k in length are split into multiple records
and can be identified as aX[Y]=

e445deb593 [AUDIT] include audit type in audit message when using printk
Currently audit drops the audit type when an audit message goes through
printk instead of the audit deamon.  This is a minor annoyance in
that the audit type is no longer part of the message and the information
the audit type conveys needs to be carried in, or derived from the
message data.

The attached patch includes the type number as part of the printk.
Admittedly it isn't the type name that the audit deamon provides but I
think this is better than dropping the type completely.

6246ccab99 [AUDIT] do not panic on exclude messages in audit_log_pid_context()
If we fail to get an ab in audit_log_pid_context this may be due to an exclude
rule rather than a memory allocation failure.  If it was due to a memory
allocation failue we would have already paniced and no need to do it again.

c0641f28dc [AUDIT] Add End of Event record
This patch adds an end of event record type. It will be sent by the kernel as
the last record when a multi-record event is triggered. This will aid realtime
analysis programs since they will now reliably know they have the last record
to complete an event. The audit daemon filters this and will not write it to
disk.

c2a7780efe [AUDIT] collect uid, loginuid, and comm in OBJ_PID records
Add uid, loginuid, and comm collection to OBJ_PID records.  This just
gives users a little more information about the task that received a
signal.  pid is rather meaningless after the fact, and even though comm
isn't great we can't collect exe reasonably on this code path for
performance reasons.

3bc217ffe6 block: kill swap_io_context()
It blindly copies everything in the io_context, including the lock.
That doesn't work so well for either lock ordering or lockdep.

There seems zero point in swapping io contexts on a request to request
merge, so the best point of action is to just remove it.
