Pull SELinux fix from Paul Moore:
 "One more small fix for SELinux: a small string length fix found by
  KASAN.

  I dislike sending patches this late in the release cycle, but this
  patch fixes a legitimate problem, is very small, limited in scope, and
  well understood.

  There are two threads with more information on the problem, the latest
  is linked below:

  Stephen points out in the thread linked above:

   'Such a setxattr() call can only be performed by a process with
    CAP_MAC_ADMIN that is also allowed mac_admin permission in SELinux
    policy. Consequently, this is never possible on Android (no process
    is allowed mac_admin permission, always enforcing) and is only
    possible in Fedora/RHEL for a few domains (if enforcing)'"
