MAC_STUB(4) FreeBSD Kernel Interfaces Manual MAC_STUB(4)
NAME
mac_stub - MAC policy stub module
SYNOPSIS
To compile the stub policy into your kernel, place the following lines in
your kernel configuration file:
options MAC
options MAC_STUB
Alternately, to load the stub module at boot time, place the following
line in your kernel configuration file:
options MAC
and in loader.conf(5):
mac_stub_load="YES"
DESCRIPTION
The mac_stub policy module implements a stub MAC policy that has no
effect on access control in the system. Unlike mac_none(4), each MAC
entry point is defined as a "no-op", so the policy module will be entered
for each event, but no change in system behavior should result.
Label Format
No labels are defined for mac_stub.

AUTHORS
This software was contributed to the FreeBSD Project by Network

the DARPA CHATS research program.
BUGS
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.
