Merge tag 'selinux-pr-20180403' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull SELinux updates from Paul Moore:
 "A bigger than usual pull request for SELinux, 13 patches (lucky!)
  along with a scary looking diffstat.

  Although if you look a bit closer, excluding the usual minor
  tweaks/fixes, there are really only two significant changes in this
  pull request: the addition of proper SELinux access controls for SCTP
  and the encapsulation of a lot of internal SELinux state.

  The SCTP changes are the result of a multi-month effort (maybe even a
  year or longer?) between the SELinux folks and the SCTP folks to add
  proper SELinux controls. A special thanks go to Richard for seeing
  this through and keeping the effort moving forward.

  The state encapsulation work is a bit of janitorial work that came out
  of some early work on SELinux namespacing. The question of namespacing
  is still an open one, but I believe there is some real value in the
  encapsulation work so we've split that out and are now sending that up
  to you"
