Title:
  Regression: Kernel update breaks all lxc-containers lxc-start failing
  with  (apparmor="DENIED" operation="mount")

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hello,
  The following recent kernel update completely break our lxc-start usage on 
precise both with precise original kernel 3.2 + also the trusty-lts-stack using 
3.13

  After installing those new kernel updates all lxc-start of a container fail 
with:
  "Permission denied - mount failed '/dev/pts/ptmx'->'/dev/ptmx'"

  with strace pointing to:
  13695 mount("/dev/pts/ptmx", "/dev/ptmx", 0x7f4d68c85d37, MS_BIND, NULL) = -1 
EACCES (Permission denied)

  and dmesg showing:
  Oct 20 10:59:00 titan226 kernel: [  663.508664] type=1400 
                  audit(1445331540.807:29): apparmor="DENIED" operation="mount" 
                  info="failed type match" error=-13 
profile="/usr/bin/lxc-start" 
                  name="/dev/ptmx" pid=2897 comm="lxc-start" 
                  srcname="/dev/pts/ptmx" flags="rw, bind"

  After downgrading kernel version the problem immediately dissappeared
  and the lxc-start for containers works again as before.

  Bad versions:
  ii  linux-image-3.13.0-66-generic    3.13.0-66.108~precise1            Linux 
kernel image for version 3.13.0 on 64 bit x86 SMP
  ii  linux-image-3.2.0-92-generic     3.2.0-92.130                      Linux 
kernel image for version 3.2.0 on 64 bit x86 SMP

  
  Good versions:
  ii  linux-image-3.13.0-61-generic    3.13.0-61.100~precise1            Linux 
kernel image for version 3.13.0 on 64 bit x86 SMP
  ii  linux-image-3.2.0-88-generic     3.2.0-88.126                      Linux 
kernel image for version 3.2.0 on 64 bit x86 SMP

  From kernel changelog maybe this other issue here maybe causing it but not 
verified:
    * SAUCE: (no-up) apparmor: fix mount not handling disconnected paths
