DESCRIPTION
The
family of functions allocates the appropriate amount of storage and initializes
Fa *mac
for use by
mac_get3.
When the resulting label is passed into the
mac_get3
functions, the kernel will attempt to fill in the label elements specified
when the label was prepared.
Elements are specified in a nul-terminated string, using commas to
delimit fields.
Element names may be prefixed with the
?
character to indicate that a failure by the kernel to retrieve that
element should not be considered fatal.
The
mac_prepare ();
function accepts a list of policy names as a parameter, and allocates the
storage to fit those label elements accordingly.
The remaining functions in the family make use of system defaults defined
in
mac.conf5
instead of an explicit
elements
argument, deriving the default from the specified object type.
mac_prepare_type ();
allocates the storage to fit an object label of the type specified by
the
name
argument.
The
mac_prepare_file_label (,);
mac_prepare_ifnet_label (,);
and
mac_prepare_process_label ();
functions are equivalent to invocations of
mac_prepare_type ();
with arguments of
Qq file ,
Qq ifnet ,
and
Qq process
respectively.
POSIX.1e is described in IEEE POSIX.1e draft 17.
Discussion of the draft
continues on the cross-platform POSIX.1e implementation mailing list.

HISTORY
Support for Mandatory Access Control was introduced in
Fx 5.0
as part of the
TrustedBSD
Project.
Support for generic object types first appeared in
Fx 5.2 .
