Title:
  Running tasks are not subject to reloaded policies

Status in AppArmor Linux application security framework:
  Fix Released
Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Saucy:
  Fix Committed
Status in “linux” source package in Trusty:
  Fix Released

Bug description:
  As of saucy, if you start /usr/bin/foo under an existing policy defined
  in /etc/apparmor.d/usr.bin.foo, then reload /etc/apparmor.d/usr.bin.foo
  with updated permissions, then the running tasks is not subject to the
  new permissions.

  A testcase is at http://people.canonical.com/~serge/aa_exec.tgz .  This
  passes in precise, and fails in saucy.

  This came up in the libvirt regression testsuite.  When it tries to
  virsh attach-device, then the existing libvirt task's policy must be
  updated to allow it to access the new device image file.  The test fails
  with EACCESS trying to open the image file after loading the new policy.
