TARGET_ARCH and TARGET. This is problematic when one has the =
(unconditional) type of assigment for CPUTYPE in /etc/make.conf.
(This would override what was set on the command line to "make
buildworld".)
Add a (horrible) kludge to Makefile.inc1 to check the type of
assignment for CPUTYPE (only for those who attempts to set it to
a different value). Fix an example make.conf. Fix the kernel's
build-tools target (aicasm only at the moment) to catch up with
bsd.cpu.mk,v 1.15 (BOOTSTRAPPING replaced with NO_CPU_CFLAGS in
Makefile.inc1's BMAKE).

Provide ugidfw, a utility to manage the ruleset provided by

Provide a library to manage user file system firewall-like rules
supported by the mac_bsdextended.ko security model. The kernel
module exports the current rule set using sysctl, and this
library provides a front end that includes support for retrieving
and setting rules, as well as printing and parsing them.
Note: as with other userland components, this is a WIP. However,
when used in combination with the soon-to-be-committed ugidfw,
it can actually be quite useful in multi-user environments to
allow the administrator to limit inter-user file operations without
resorting to heavier weight labeled security policies.

Teach mount(8) to understand the MNT_MULTILABEL flag, which is used
to determine whether a file system operates with individual per-vnode
labels, or treats the entire file system as a single object with a
single (mount) label. The behavior here will probably evolve some
now that nmount(2) is available and can more flexibly support mount
options.

Invoke appropriate MAC entry points for a number of VFS-related
operations in the Linux ABI module. In particular, handle uselib
in a manner similar to open() (more work is probably needed here),
as well as handle statfs(), and linux readdir()-like calls.

Hook up various policy modules to the kernel build.
Note that a number of these modules require futher entry point commits
in the remainder of the kernel to become fully functional, but enough
of the pieces are in place to allow experimentation.
Note also that it would be desirable to not build the mac_*.ko modules
if 'options MAC' is not defined in the kernel configuration, because
the resulting modules are not useful without the kernel option. There
doesn't appear to be precedent for a way to do this -- for example,
we allow ipfw.ko to be built even if 'options NETINET' isn't defined.
Suggests welcomed on the "best" way to do this.
