SRU
1. Impact of the bug is low for stable releases, unless the user is
having a kernel issue and the kernel team asks the user to run an
upstream kernel.
2. This has not been addressed in the development branch (it isn't open
yet).
3. This is r1430 from the apparmor-2.5 branch, which is part of AppArmor
2.5.1. This patch is not included in the 2.5.1rc1 package in maverick,
but the patch is quite small (see the linked branch). This patch will
cause apparmor_parser to exit with error it can't find the
/sys/kernel/security/apparmor/features file.
4. TEST CASE:
Run an upstream kernel, and try to use the parser. Eg:
$ sudo apparmor_parser -r -W -T /etc/apparmor.d/usr.sbin.cupsd
5. The regression potential of the patch is low, since Ubuntu releases
have the compatibility patch (and therefore
/sys/kernel/security/apparmor/features).
