Subject: [PATCH 0/11 v3] audit: Fix various races when tagging and untagging mounts
Date: Tue,  4 Sep 2018 18:06:20 +0200	[thread overview]
Message-ID: <20180904160632.21210-1-jack@suse.cz> (raw)

Hello,

this is the third 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 v2:
* Fixed up mark freeing to use proper pointer as pointed out by Amir
* Changed some naming based on Paul's review

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
