Pull selinux updates from Paul Moore:
 "A small pull request this time, just three patches, and one of these
  is just a comment update (swap the FSF physical address for a URL).

  The other two patches are small bug fixes found by szybot/syzkaller;
  they individual patch descriptions should tell you all you ever wanted
  to know"

* tag 'selinux-pr-20180130' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux:
  selinux: skip bounded transition processing if the policy isn't loaded
  selinux: ensure the context is NUL terminated in security_context_to_sid_core()
  security: replace FSF address with web source in license notices
