     mac_test - MAC framework testing policy

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

           options MAC
           options MAC_TEST

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

           options MAC

     and in loader.conf(5):


     The mac_test policy module implements a testing facility for the MAC
     framework.  Among other things, mac_test will try to catch corrupt labels
     the system is attempting to destroy and drop to the debugger.
     Additionally, a set of statistics regarding the number of times various
     MAC framework entry points have been called is stored in the
     security.mac.test sysctl(8) tree.

   Label Format
     No labels are defined for mac_test.

     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(9)

     The mac_test policy module first appeared in FreeBSD 5.0 and was
     developed by the TrustedBSD Project.

     This software was contributed to the FreeBSD Project by Network
     Associates 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.

     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.
