Description Steve Grubb 2008-04-15 15:00:18 UTC 
Description of problem:
Audit rules with >= get converted to != by libaudit. For example, the rule:
auditctl -a always,exit -S open -F 'auid>=500'

when you run auditctl -l, the was sent into the kernel as auid!=500 which is not
what is intended.

Also, there is a memory leak on EOE records. The 5.3 kernel will start sending
EOE records so this should be fixed in case they upgrade the kernel and not the
audit daemon.

Comment 4 Steve Grubb 2008-04-20 21:22:50 UTC 
audit-1.6.5-9.el5 was built to address this problem.
Comment 6 Eduard Benes 2008-04-22 13:58:59 UTC 
Steve, I'm not able to reproduce the '!=' bug using older audit packages. Do 
you have any idea what could be causing this? Here is a log using old audit-
1.6.5-6.el5 packages, it should FAIL but as you can see it passes on all archs. 
Tried 1.6.5-{6,7,8,9} and all passed.

Sample log:
