.In bsm/libbsm.h
|
||
|
|
.Ft int
|
||
|
|
.Fn au_get_state "void"

|
||
|
|
.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm au_notify
|
||
|
|
audit notification API tracks audit state in a form permitting efficient
|
||
|
|
update, avoiding frequent system calls to check the kernel audit state.
|
||
|
|
It is implemented only for Darwin/Mac OS X.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Fn au_get_state
|
||
|
|
function provides a lightweight way to check whether or not auditing is
|
||
|
|
enabled.
|
||
|
|
If a client wants to use this function to determine whether an entire
|
||
|
|
series of audit calls should be made -- as in the common case of a caller
|
||
|
|
building a set of tokens, then writing them -- it should cache the audit
|
||
|
|
status in a local variable.
|
||
|
|
This function always returns the current state of auditing.
|
||
|
|
If audit notification has not already been initialized by calling
|
||
|
|
.Fn au_notify_initialize
|
||
|
|
it will be automatically initialized on the first call of
|
||
|
|
this function.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Fn au_notify_initialize
|
||
|
|
function initializes audit notification.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Fn au_notify_terminate
|
||
|
|
function cancels audit notification and frees the resources associated with it.
|
||
|
|
Responsible code that no longer needs to use
|
||
|
|
.Fn au_get_state
|
||
|
|
should call this function.
|
||
|
|
.Sh RETURN VALUES
|
||
|
|
If no error occurred the
|
||
|
|
.Fn au_get_state
|
||
|
|
function returns
|
||
|
|
.Dv AUC_NOAUDIT
|
||
|
|
if auditing is disabled or suspended, and
|
||
|
|
.Dv AUC_AUDITING
|
||
|
|
if auditing is enabled and active.
|
||
|
|
Otherwise, the function can return any of the errno values defined for
|
||
|
|
.Xr setaudit 2 ,
|
||
|
|
or
|
||
|
|
.Dv AU_UNIMPL
|
||
|
|
if audit does not appear to be supported by the system.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Fn au_notify_initialize
|
||
|
|
function returns 0 on success,
|
||
|
|
.Dv AU_UNIMPL
|
||
|
|
if audit does not appear to be supported by the system,
|
||
|
|
or one of the status codes defined in
|
||
|
|
.In notify.h
|
||
|
|
on Mac OS X to indicate the error.
|
||
|
|
.Pp
|
||
|
|
The
|
||
|
|
.Fn au_notify_terminate
|
||
|
|
function returns 0 on success, or \-1 on failure.

.Sh HISTORY
|
||
|
|
The OpenBSM implementation was created by McAfee Research, the security

division of McAfee Inc., under contract to Apple Computer, Inc., in 2004.
|
||
|
|
It was subsequently adopted by the TrustedBSD Project as the foundation for
|
||
|
|
the OpenBSM distribution.
