I have the following in my test audit configuration on RHEL4 U5:

-a entry,always -S exit -S exit_group -S execve -S fork -S vfork -S
clone

My first observation is that I've never seen an audit record with pid=1.
It's fairly easy to reproduce this one. Log in at the console, then log
out. You'll see a process execve() a new mingetty, but you won't see the
fork, vfork or clone which created it.

My second observation is a bit more complex. I have a box running Oracle
RAC. RAC runs some particularly nasty scripts on a regular basis (once
per second). In outline, it does this:

In inittab:
respawn:init.cssd

In init.cssd:
while true; do
    init.cssd runcheck
done

I see that a process execs 'init.cssd runcheck' once per second.
However, I do not see a process fork, vfork or clone that process. This
suggests that audit data isn't being produced for the top level
init.cssd job.

Does this ring any bells? Is there some other method of process creation
I'm not aware of? Is init intentionally not audited, and if so, how do I
audit it?

Thanks,

Matt
