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.
