History
Robert Watson 95fab37ea8 Begin committing support for Mandatory Access Control and extensible 
kernel access control.  The MAC framework permits loadable kernel
modules to link to the kernel at compile-time, boot-time, or run-time,
and augment the system security policy.  This commit includes the
initial kernel implementation, although the interface with the userland
components of the oeprating system is still under work, and not all
kernel subsystems are supported.  Later in this commit sequence,
documentation of which kernel subsystems will not work correctly with
a kernel compiled with MAC support will be added.

kern_mac.c contains the body of the MAC framework.  Kernel and
user APIs defined in mac.h are implemented here, providing a front end
to loaded security modules.  This code implements a module registration
service, state (label) management, security configuration and policy
composition.
