These patches have been built on Fedora 27 with kernel-4.16.0-0.rc1 plus
the following userspace patches to enable testing:

1) Updates to libsepol 2.7 to support the sctp portcon statement.
   The patch is available from:
         http://arctic.selinuxproject.org/~rhaines/selinux-sctp/
         selinux-Add-support-for-the-SCTP-portcon-keyword.patch

2) Updates to the SELinux Test Suite adding SCTP tests. Please read the
   selinux-testsuite/README.sctp for details. The patch is available from:
         http://arctic.selinuxproject.org/~rhaines/selinux-sctp/
         selinux-testsuite-Add-SCTP-test-support.patch

3) Updates to lksctp-tools that show SELinux info in sctp_darn and
   sctp_test. It also contains a minor patch for test_1_to_1_connect.c
   as when CIPSO/CALIPSO configured, NetLabel returns a different error
   code for illegal addresses in test 5. The patch is available from:
         http://arctic.selinuxproject.org/~rhaines/selinux-sctp/
         lksctp-tools-Add-SELinux-support-to-sctp_test-and-sc.patch

All SCTP lksctp-tools/src/func_tests run correctly in enforcing mode.

All SCTP regression tests "./sctp-tests run" run correctly in enforcing
mode. These tests are obtained from: https://github.com/sctp/sctp-tests

The selinux-testsuite patch also adds remote tests (that need some manual
configuration). These are useful for testing CIPSO/CALIPSO over a network
with a number of categories to produce large ip option fields with various
message sizes forcing fragmentation etc..

Changes since RFC Patch:
Removed the NetLabel patch (was [RFC PATCH 4/5] netlabel: Add SCTP support)
as re-engineered. However this patchset will require the NetLabel
patch at [1] to fully run the SCTP selinux-testsuite.

V1 Changes:
PATCH 1/4
Remove unused parameter from security_sctp_assoc_request().
Reformat and update LSM-sctp.rst documentation.
PATCH 2/4
Add variables and RCU locks as requested in [2] to support IP options.
PATCH 3/4
Added security_sctp_assoc_request() hook to sctp_sf_do_unexpected_init()
and sctp_sf_do_5_2_4_dupcook().
Removed security_sctp_assoc_request() hook from sctp_sf_do_5_1C_ack() as
no longer required.
PATCH 4/4
Reformat and update SELinux-sctp.rst documentation.
Remove bindx and connectx permissions.
Rework selinux_socket_connect() and selinux_netlbl_socket_connect() to
utilise helpers for code reuse.
Add spinlock to selinux_sctp_assoc_request().
Remove unused parameter from security_sctp_assoc_request().
Use address->sa_family == AF_INET in *_bind and *_connect to ensure
correct address type.
Minor cleanups.

V2 Changes:
PATCH 4/4 - Remove spin lock from selinux_sctp_assoc_request()
PATCH 4/4 - Fix selinux_sctp_sk_clone() kbuild test robot catch [3]

V3 Changes:
PATCH 2/4 - Account for IP options length in sctp.h sctp_frag_point() by
Marcelo

V4 Changes:
PATCH 1/4 - Move specific SELinux descriptions from LSM-sctp.rst and
lsm_hooks.h to SELinux-sctp.rst in PATCH 4/4
PATCH 4/4 - Rename selinux_netlbl_sctp_socket_connect() to
selinux_netlbl_socket_connect_locked() and move description comments to
selinux_sctp_bind_connect()

V5 Change: Rework selinux_netlbl_socket_connect() and
selinux_netlbl_socket_connect_locked as requested by Paul.

V6 Changes:
Rework SCTP patches 2/4 and 3/4 as there have been major SCTP updates since
kernel 4.14.

[3] https://marc.info/?l=selinux&m=151198281817779&w=2

Richard Haines (4):
  security: Add support for SCTP security hooks
  sctp: Add ip option support
  sctp: Add LSM hooks
  selinux: Add SCTP support

Marcelo, or any other SCTP folks, do the SCTP changes still look okay
to you?  I'd like to merge these into the selinux/next tree by the end
of the week ...

I had a few comments that I just posted.
