Merge tag 'selinux-pr-20181115' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull SELinux fixes from Paul Moore:
"Two small SELinux fixes for v4.20.
Ondrej's patch adds a check on user input, and my patch ensures we
don't look past the end of a buffer.
Both patches are quite small and pass the selinux-testsuite"
* tag 'selinux-pr-20181115' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux:
selinux: fix non-MLS handling in mls_context_to_sid()
selinux: check length properly in SCTP bind hook
