Title:
  [krillin] apparmor fd_inheritance regression test causes kernel to
  crash

Status in apparmor package in Ubuntu:
  New

Bug description:
  On krillin with vivid-proposed, running the fd_inheritance test from
  the apparmor regression tests causes the kernel to crash and
  spontaneously reboot the device:

  phablet@ubuntu-phablet:~/src/apparmor-2.9.1/tests/regression/apparmor$ logger "running fd_inheritance tests now"
  phablet@ubuntu-phablet:~/src/apparmor-2.9.1/tests/regression/apparmor$ sudo sh -c 'VERBOSE=1 bash fd_inheritance.sh'
  ok: fd inheritance; unconfined -> unconfined
  ok: fd inheritance; confined -> unconfined
  ok: fd inheritance; confined (bad perm) -> unconfined
  ok: fd inheritance; confined (no perm) -> unconfined
  ok: fd inheritance; unconfined -> confined
  ok: fd inheritance; unconfined -> confined (no perm)
  ok: fd inheritance; confined -> confined
  ok: fd inheritance; confined (bad perm) -> confined
  ok: fd inheritance; confined (no perm) -> confined
  ok: fd inheritance; confined -> confined (bad perm)
  [device reboots here]

  This is what syslog sees before it falls over, though nothing after the logger invocation makes it to the disk:

  Note that because krillin is based on a 3.4 kernel, dmesg -w does not
  work to see anything emitted by the kernel before the spontaneous
  reboot.
