.Dd December 1, 2002 .Dt MAC_STUB 4 .Os .Sh NAME .Nm mac_stub .Nd "MAC policy stub module" .Sh SYNOPSIS To compile the stub policy into your kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "options MAC" .Cd "options MAC_STUB" .Ed
p Alternately, to load the stub module at boot time, place the following line in your kernel configuration file: d -ragged -offset indent .Cd "options MAC" .Ed
p and in .Xr loader.conf 5 : d -literal -offset indent mac_stub_load="YES" .Ed .Sh DESCRIPTION The .Nm policy module implements a stub MAC policy that has no effect on access control in the system. Unlike .Xr mac_none 4 , each MAC entry point is defined as a .Dq no-op , so the policy module will be entered for each event, but no change in system behavior should result. .Ss Label Format No labels are defined for .Nm . .Sh SEE ALSO .Xr mac 4 , .Xr mac_biba 4 , .Xr mac_bsdextended 4 , .Xr mac_ifoff 4 , .Xr mac_lomac 4 , .Xr mac_mls 4 , .Xr mac_none 4 , .Xr mac_partition 4 , .Xr mac_portacl 4 , .Xr mac_seeotheruids 4 , .Xr mac_test 4 , .Xr mac 9 .Sh HISTORY The .Nm policy module first appeared in .Fx 5.1 and was developed by the .Tn TrustedBSD Project. .Sh AUTHORS This software was contributed to the .Fx Project by Network Associates Labs, the Security Research Division of Network Associates Inc. under DARPA/SPAWAR contract N66001-01-C-8035
q Dq CBOSS , as part of the DARPA CHATS research program. .Sh BUGS See .Xr mac 9 concerning appropriateness for production use. The .Tn TrustedBSD MAC Framework is considered experimental in .Fx .
p 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.
