.Dd December 9, 2002 .Dt MAC_PARTITION 4 .Os .Sh NAME .Nm mac_partition .Nd "process partition policy" .Sh SYNOPSIS To compile the process partition policy into your kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "options MAC" .Cd "options MAC_PARTITION" .Ed
p Alternately, to load the process partition 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_partition_load="YES" .Ed .Sh DESCRIPTION The .Nm policy module implements a process partition policy, which allows administrators to place running processes into .Dq partitions , based on their numeric process partition (specified in the process's MAC label). Processes with a specified partition can only see processes that are in the same partition. If no partition is specified for a process, it can see all other processes in the system (subject to other MAC policy restrictions not defined in this man page). No provisions for placing processes into multiple partitions are available. .Ss Label Format Partition labels take on the following format:
p .Sm off .Dl Li partition / Ar value .Sm on
p Where .Ar value can be any integer value or .Dq Li none . For example: d -literal -offset indent partition/1 partition/20 partition/none .Ed .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_portacl 4 , .Xr mac_seeotheruids 4 , .Xr mac_test 4 , .Xr maclabel 7 , .Xr mac 9 .Sh HISTORY The .Nm policy module first appeared in .Fx 5.0 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.
