.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:
|
|
.Bd -ragged -offset indent
|
|
.Cd "options MAC"
|
|
.Cd "options MAC_PARTITION"
|
|
.Ed
|
|
.Pp
|
|
Alternately, to load the process partition module at boot time,
|
|
place the following line in your kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "options MAC"
|
|
.Ed
|
|
.Pp
|
|
and in
|
|
.Xr loader.conf 5 :
|
|
.Bd -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:
|
|
.Pp
|
|
.Sm off
|
|
.Dl Li partition / Ar value
|
|
.Sm on
|
|
.Pp
|
|
Where
|
|
.Ar value
|
|
can be any integer value or
|
|
.Dq Li none .
|
|
For example:
|
|
.Bd -literal -offset indent
|
|
partition/1
|
|
partition/20
|
|
partition/none

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
policy module first appeared in
|
|
.Fx 5.0
|
|
and was developed by the
|
|
.Tn TrustedBSD
|
|
Project.

|
|
.Sh BUGS
|
|
See
|
|
.Xr mac 9
|
|
concerning appropriateness for production use.
|
|
The
|
|
.Tn TrustedBSD
|
|
MAC Framework is considered experimental in
|
|
.Fx .
|
|
.Pp
|
|
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.
