.Dt MAC_STUB 4
|
|
.Sh NAME
|
|
.Nm mac_stub
|
|
.Nd "MAC policy stub module"
|
|
.Sh SYNOPSIS
|
|
To compile the sample policy
|
|
into your kernel, place the following lines in your kernel
|
|
configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "options MAC"
|
|
.Cd "options MAC_STUB"
|
|
.Ed
|
|
.Pp
|
|
Alternately, to load the sample 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_stub_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
policy module implements a sample 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 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

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 .
|
|
.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.
