Subject: [PATCH 0/10 v2] audit: Fix various races when tagging and untagging mounts
Date: Tue, 10 Jul 2018 12:02:06 +0200 [thread overview]
Message-ID: <20180710100217.12866-1-jack@suse.cz> (raw)
Hello,
this is a second revision of the series that addresses problems I have
identified when trying to understand how exactly is kernel/audit_tree.c using
generic fsnotify framework. I hope I have understood all the interactions right
but careful review is certainly welcome.
The patches have been tested by a stress test I have written which mounts &
unmounts filesystems in the directory tree while adding and removing audit
rules for this tree in parallel and accessing the tree to generate events.
Still some real-world testing would be welcome.
Changes since v1:
* Split the last patch to ease review
* Rewrite test script so that it can be included in audit testsuite
* Some cleanups and improvements suggested by Amir
Honza
