MAC_STUB(4)	       FreeBSD Kernel Interfaces Manual		   MAC_STUB(4)

NAME
     mac_stub -- MAC policy stub module

SYNOPSIS
     To	compile	the stub policy	into your kernel, place	the following lines in
     your kernel configuration file:

	   options MAC
	   options MAC_STUB

     Alternately, to load the stub module at boot time,	place the following
     line in your kernel configuration file:

	   options MAC

     and in loader.conf(5):

	   mac_stub_load="YES"

DESCRIPTION
     The mac_stub policy module	implements a stub MAC policy that has no
     effect on access control in the system.  Unlike mac_none(4), each MAC
     entry point is defined as a ``no-op'', so the policy module will be
     entered for each event, but no change in system behavior should result.

   Label Format
     No	labels are defined for mac_stub.

SEE ALSO
     mac(4), mac_biba(4), mac_bsdextended(4), mac_ifoff(4), mac_lomac(4),
     mac_mls(4), mac_none(4), mac_partition(4),	mac_portacl(4),
     mac_seeotheruids(4), mac_test(4), mac(9)

HISTORY
     The mac_stub policy module	first appeared in FreeBSD 5.1 and was devel-
     oped by the TrustedBSD Project.

AUTHORS
     This software was contributed to the FreeBSD Project by Network Asso-
     ciates Labs, the Security Research	Division of Network Associates Inc.
     under DARPA/SPAWAR	contract N66001-01-C-8035 (``CBOSS''), as part of the
     DARPA CHATS research program.

BUGS
     See mac(9)	concerning appropriateness for production use.	The TrustedBSD
     MAC Framework is considered experimental in FreeBSD.

     While the MAC Framework design is intended	to support the containment of
     the root user, not	all attack channels are	currently protected by entry
     point checks.  As such, MAC Framework policies should not be relied on,
     in	isolation, to protect against a	malicious privileged user.
