log messages
by Bill Tangren
When I restart my auditd daemon, I get a number of messages in
/var/log/messages that look like this:
Nov 2 10:27:25 charon kernel: audit(1194013645.793:6808): auid=500
removed an audit rule
What does this mean? Does it mean that some of my rules in
/etc/audit.rules are improper, and the server is removing them?
TIA,

I am running audit-1.0.15-3.EL4 on a RHEL ES 4 system, fully patched. I am
trying to learn the meaning of the output of aureport. For example, if I
want to look at failed events, could you tell me what the following means?
That is, how do I know from this what is failing, and why?
[root@doggett ~]# /sbin/aureport -e --failed -ts yesterday 00:00:00 -te
today 00:00:00
Event Report

# date time event type auid

[PATCH] audit: clear thread flag for new children
by Tony Jones
From: Tony Jones <tonyj(a)suse.de>
Minor performance enhancement.
Thread flag TIF_SYSCALL_AUDIT is not cleared for new children when audit
context creation has been disabled (auditctl -e0). This can cause new children
forked from a parent created when audit was enabled to not take the fastest
syscall path thru entry.S
