40 To compile the process partition policy into your kernel,
41 place the following lines in your kernel
43 .Bd -ragged -offset indent
45 .Cd "options MAC_PARTITION"
48 Alternately, to load the process partition module at boot time,
49 place the following line in your kernel configuration file:
50 .Bd -ragged -offset indent
56 .Bd -literal -offset indent
57 mac_partition_load="YES"
62 policy module implements a process partition policy,
63 which allows administrators to place running processes into
65 based on their numeric process partition
66 (specified in the process's MAC label).
67 Processes with a specified partition can only see processes that are in the
69 If no partition is specified for a process, it can see all other processes
71 (subject to other MAC policy restrictions not defined in this man page).
72 No provisions for placing processes into multiple partitions are available.
74 Partition labels take on the following format:
77 .Dl Li partition / Ar value
82 can be any integer value or

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