Bug description:
  The Linux kernel through 3.17.4 does not properly restrict dropping of
  supplemental group memberships in certain namespace scenarios, which
  allows local users to bypass intended file permissions by leveraging a
  POSIX ACL containing an entry for the group category that is more
  restrictive than the entry for the other category, aka a "negative
  groups" issue, related to kernel/groups.c, kernel/uid16.c, and
  kernel/user_namespace.c.
