[Bug 1215386] [NEW] lxc-start tries to change apparmor profile to unconfined

[Andre Nathan]

Public bug reported:

When starting a container that has 'lxc.aa_profile = unconfined' on its
configuration file, lxc-start fails with

  lxc-start: Read-only file system - failed to change apparmor profile
to unconfined

This happens because the buffer used by lxc-start to read the process'
apparmor profile from /proc/<PID>/attr/current is not properly NULL-
terminated. A patch for this has been applied upstream and is available
at
https://github.com/lxc/lxc/commit/626ad11bfee3e12e675f51e92920030a6f383b19

Ubuntu Release: Ubuntu 13.04
