Title:
  dnsmasq profile incomplete for lxc usage

Status in AppArmor Linux application security framework:
  Fix Released
Status in apparmor package in Ubuntu:
  Fix Released

Bug description:
  [impact]

  This bug prevents the proper functioning of dnsmasq under lxc

  [steps to reproduce]

  1) install lxc
  2) start container, do dns lookups within it
  3) with the fix applied,  dnsmasq in the host os should not generate
  apparmor rejections in syslog

  [regression potential]

  The change in the patch for this bug is a slight loosening of the
  apparmor policy for dnsmasq. The risk of an introduced regression
  is small.

  [original description]

  Hi,

  I am using the dnsmasq profile with lxc, and I am getting DENIED
  messages like:

  Dec 16 22:26:58 superstar kernel: [226445.568383] type=1400
  audit(1418768818.310:865): apparmor="DENIED" operation="truncate"
  profile="/usr/sbin/dnsmasq" name="/var/lib/misc/dnsmasq.lxcbr0.leases"
  pid=1472 comm="dnsmasq" requested_mask="w" denied_mask="w" fsuid=118
  ouid=0

  Adding rw for that path obviously makes it go away, and seems like a
  reasonable change.

  Thanks,

  James
