Simon J. Gerraty 1554ba03b6 Add mac_grantbylabel
This module allows controlled privilege escallation via mac labels
securely associated with a process via mac_veriexec.

There are over 700 PRIV_* but we can compress many of them into
a single GBL_* thus constraining the size of gbl labels.

The goal is to allow a daemon to run as an unprivileged process while
still being able a set of privileged operations needed.

We add APIs to libveriexec so that userland processes can check labels
and an exec_script API that allows a suitably labeled process to run
something like a python interpreter directly if necessary;
overcomming the 'indirect' flag applied to the interpreter.

Add -l option to sbin/veriexec to report labels.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
