Robert Watson 5e386598a6 Merge OpenBSM 1.2-alpha5 from vendor branch to FreeBSD -CURRENT: 
- Add a new "qsize" parameter in audit_control and the getacqsize(3) API to
  query it, allowing to set the kernel's maximum audit queue length.
- Add support to push a mapping between audit event names and event numbers
  into the kernel (where supported) using new A_GETEVENT and A_SETEVENT
  auditon(2) operations.
- Add audit event identifiers for a number of new (and not-so-new) FreeBSD
  system calls including those for asynchronous I/O, thread management, SCTP,
  jails, multi-FIB support, and misc. POSIX interfaces such as
  posix_fallocate(2) and posix_fadvise(2).
- On operating systems supporting Capsicum, auditreduce(1) and praudit(1) now
  run sandboxed.
- Empty "flags" and "naflags" fields are now permitted in audit_control(5).

Many thanks to Christian Brueffer for producing the OpenBSM release and
importing/tagging it in the vendor branch.  This release will allow improved
auditing of a range of new FreeBSD functionality, as well as non-traditional
events (e.g., fine-grained I/O auditing) not required by the Orange Book or
Common Criteria.

.Sh DESCRIPTION
These interfaces support the allocation of BSM audit tokens, represented by
.Vt token_t ,
for various data types.
.Pp
.Xr au_errno_to_bsm 3
must be used to convert local
.Xr errno 2
errors to BSM error numbers before they are passed to
.Fn au_to_return ,
.Fn au_to_return32 ,
and
.Fn au_to_return64 .
.Sh RETURN VALUES
On success, a pointer to a
.Vt token_t
will be returned; the allocated
.Vt token_t
can be freed via a call to
.Xr au_free_token 3 .
On failure,
.Dv NULL
will be returned, and an error condition returned via
.Va errno .
.Sh SEE ALSO
.Xr au_errno_to_bsm 3 ,
.Xr libbsm 3
.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.
