Hello,
I've discovered another situation where audit is still auditing
itself. When I have audit enabled but I'm not running the daemon, and
add rules like:
# auditctl -a entry,always -S open
# auditctl -a entry,always -S close
Doing something like 'auditctl -l' floods the console with audit
records.
Has anyone else seen this? I'm running the .81 kernel.
Thanks,
Amy

This could be normal depending on your rules and what pid it's reporting. If
it reports the auditd pid, we have a problem. If it reports auditctl's pid,
this might be expected.

If there's no auditd running, then I don't think the kernel will know
which process/threads to exclude since its using auditd's pid to decide
that. Even then, wouldn't auditctl's open/close syscalls be audited
with the rules you're using? What would cause them to be excluded?
What do the audit records look like?

I wouldn't worry too much about this effect, since unconditionally
auditing all open and close calls is a really bad idea anyway; you'll
usually want "entry,possible" combined with watches instead. So unless it
goes into an infinite loop of audit records triggered by printing audit
records I'd consider this to be an acceptable oddity.

That was a bad diagnosis. The problem I see is an effect of running
sudo with this rule:
auditctl -a entry,always -S close
Using the following set of rules produces normal-looking behavior,
i.e. no audit record floods.
auditctl -w /usr/bin/sudo -p x
auditctl -a entry,possible -S close
My apologies for the false alarm.
