Introduce support for Mandatory Access Control and extensible
kernel access control. 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.
