Steve,
Please find a patch against 2.3.6 that, when checkpointing, ausearch
will only use the recorded event time in the checkpoint file when
deciding what complete events to display. Basically, it will display all
complete events found after the event time found in the checkpoint file.
Normally, one would use checkpointing in a periodic script that records
all 'new' audit events. Should certain errors occur, we need to recover
and continue to record 'new' audit events. This option allows use to do
a 'brute force' recovery by finding all events since the last recorded
time we have in the checkpoint file.
For example, the core of a periodic script may contain
ausearch --checkpoint /usr/security/auditd_checkpoint.txt -i
_aus=$?
if test ${_aus} -eq 10 -o ${_aus} -eq 11 -o ${_aus} -eq 12
then
ausearch --checkpoint /usr/security/auditd_checkpoint.txt \
--checkpoint-time-only -i
fi

I'd like to look at these two pieces separately. Let's have 1 bug/feature per
patch. This way if something looks good, it can be applied immediately.
Whereas if something needs more discussion, it would block application of the
part that is good.

I suppose it should be. What is in the release is decided by
automake/autoconf. If there are any mistakes in the Makefile.am file, I would
take a patch.

The audit package release is done by a script that pretty much does the
following (its way more complicated than this, but this is the essential
pieces):
mkdir audit
cd audit
svn co
http://svn.fedorahosted.org/svn/audit/trunk .
./autogen.sh
./configure
make -j 8 distcheck
If it finishes saying it created the tar ball, I send it to rawhide to make
sure it builds on a current OS. If that is also successful, then I push it to
my people page and then commit a branch in svn. I also run the development
audit package on all my systems during the whole development cycle to make
sure bugs are fixed, nothing new shows up, and its builds under normal
conditions.
So, anything that is there, is because autotools think it should be there
unless I made a mistake in a Makefile.am. :-) Patches are welcome.
Thanks,
-Steve
