|
.Fn mac_prepare_process_label "mac_t *mac"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
family of functions allocates the appropriate amount of storage and initializes
|
|
.Fa *mac
|
|
for use by
|
|
.Xr mac_get 3 .
|
|
When the resulting label is passed into the
|
|
.Xr mac_get 3
|
|
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
|
|
.Dv ?
|
|
character to indicate that a failure by the kernel to retrieve that
|
|
element should not be considered fatal.
|
|
.Pp
|
|
The
|
|
.Fn 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
|
|
.Xr mac.conf 5
|
|
instead of an explicit
|
|
.Va elements
|
|
argument, deriving the default from the specified object type.
|
|
.Pp
|
|
.Fn mac_prepare_type
|
|
allocates the storage to fit an object label of the type specified by
|
|
the
|
|
.Va name
|
|
argument.
|
|
The
|
|
.Fn mac_prepare_file_label ,
|
|
.Fn mac_prepare_ifnet_label ,
|
|
and
|
|
.Fn mac_prepare_process_label
|
|
functions are equivalent to invocations of
|
|
.Fn mac_prepare_type
|
|
with arguments of
|
|
.Qq file ,
|
|
.Qq ifnet ,
|
|
and
|
|
.Qq process
|
|
respectively.

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