[Bug 1375416] Re: AppArmor leaks kernel memory during profile reloads
possibly trusty, though I did do a kmemleak check at the time and didn't
notice anything. There where leaks during its dev cycle but I got at
least most of them.
Lucid and precise are very different in their code base, and while I
won't claim there aren't leaks, they are much less likely. The list
management and reference counting are simpler, nor do they have the rcu
changes etc.

Title:
AppArmor leaks kernel memory during profile reloads
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
The kmemleak kernel debugging system indicates that AppArmor leaks
kernel memory during profile reloads.
I've attached a script (test.sh) that I can consistently reproduce the
kmemleak report with.
I've also attached the output of the script, which includes the
kmemleak report.
These leaks can be reproduced with debug kernel builds of
Ubuntu-3.16.0-16.22 and Ubuntu-3.16.0-19.26, meaning that it is
present before and after the apparmor 3 RC 1 sync.
