Description Steve Grubb 2005-06-15 16:02:23 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.0.4-1.3.1 Firefox/1.0.4

Description of problem:
When file system watches are set on block devices and triggered, it overflows the backlog many, many times. Block devices do not need to be watched and something may be done to disallow monitoring them. This also points out a case where some rate limiting on syscall exit may be done.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. New feature

There's a more generic problem here with the backlog overflowing.

We can slow down the process being audited by making it wait for space on the
backlog queue instead of just failing. This is done in audit.63.
