     mac(4), mac(9)

STANDARDS
     POSIX.1e is described in IEEE POSIX.1e draft 17.  Discussion of the draft
     continues on the cross-platform POSIX.1e implementation mailing list.  To
     join this list, see the FreeBSD POSIX.1e implementation page for more
     information.

HISTORY
     Support for Mandatory Access Control was introduced in FreeBSD 5.0 as
     part of the TrustedBSD Project.

BUGS
     POSIX.1e specifies that mac_free() will be used to free text strings
     created using mac_to_text(3).  Because mac_t is a complex structure in
     the TrustedBSD implementation, mac_free() is specific to mac_3, and must
     not be used to free the character strings returned from mac_to_text().
     Doing so may result in undefined behavior.
