STANDARDS    [Toc]    [Back]

     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    [Toc]    [Back]

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

BUGS    [Toc]    [Back]

     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 that type, and must
     not be used to free the character strings returned from mac_to_text().
     Doing so may result in undefined behavior, including application failure.
