contrib/openbsm (svn merge) and src/sys/{bsm,security/audit} (manual
merge). Add libauditd build parts and add to auditd's linkage;
force libbsm to build before libauditd.
OpenBSM history for imported revisions below for reference.

OpenBSM 1.1 alpha 4
- With the addition of BSM error number mapping, we also need to map the
local error number passed to audit_submit(3) to a BSM error number,
rather than have the caller perform that conversion.
- Reallocate user audit events to avoid collisions with Solaris; adopt a
more formal allocation scheme, and add some events allocated in Solaris
that will be of immediate use on other platforms.
- Add an event for Calife.
- Add au_strerror(3), which allows generating strings for BSM errors
directly, rather than requiring applications to map to the local error
space, which might not be able to entirely represent the BSM error
number space.
- Major auditd rewrite for launchd(8) support. Add libauditd library
that is shared between launchd and auditd.
- Add AUDIT_TRIGGER_INITIALIZE trigger (sent via 'audit -i') for
(re)starting auditing under launchd(8) on Mac OS X.
- Add 'current' symlink to active audit trail.
- Add crash recovery of previous audit trail file when detected on audit
startup that it has not been properly terminated.
- Add the event AUE_audit_recovery to indicated when an audit trail file
has been recovered from not being properly terminated. This event is
stored in the new audit trail file and includes the path of recovered
audit trail file.
- Mac OS X and FreeBSD dependent code in auditd.c is separated into
auditd_darwin.c and auditd_fbsd.c files.
- Add an event for the posix_spawn(2) and fsgetpath(2) Mac OS X system
calls.
- For Mac OS X, we use ASL(3) instead of syslog(3) for logging.
- Add support for NOTICE level logging.
OpenBSM 1.1 alpha 3
- Add two new functions, au_bsm_to_errno() and au_errno_to_bsm(), to map
between BSM error numbers (largely the Solaris definitions) and local
errno(2) values for 32-bit and 64-bit return tokens. This is required
as operating systems don't agree on some of the values of more recent
error numbers.
- Fix a bug how au_to_exec_args(3) and au_to_exec_env(3) calculates the
total size for the token. This buge.
- Deprecated Darwin constants, such as TRAILER_PAD_MAGIC, removed.

.Sh SYNOPSIS
|
|
.In bsm/libbsm.h
|
|
.Ft int
|
|
.Fn au_bsm_to_errno "u_char bsm_error" "int *errorp"
|

.Fn au_errno_to_bsm "int error"
|

.Ft const char *
|
|
.Fn au_strerror "int bsm_error"
|
|
.Sh DESCRIPTION
|
|
These interfaces may be used to convert between the local (
|
|
.Xr errno 2 )
|
|
and BSM error number spaces found in BSM return tokens.
|
|
.Pp
|
|
The
|
|
.Fn au_bsm_to_errno
|
|
function accepts a BSM error value,
|
|
.Fa bsm_error,
|
|
and converts it to an
|
|
.Xr errno 2
|
|
that will be stored in the integer pointed to by
|
|
.Fa errorp
|
|
if successful.
|
|
This call will fail if the BSM error cannot be mapped into a local error
|
|
number, which may occur if the return token was generated on another
|
|
operating system.
|
|
.Pp
|
|
.Fn au_errno_to_bsm
|
|
function accepts a local
|
|
.Xr errno 2
|
|
value, and returns the BSM error number for it.
|
|
This call cannot fail, and instead returns a BSM error number indicating to
|
|
a later decoder that the error could not be encoded.
|
|
.Pp
|
|
The
|
|
.Fn au_strerror
|
|
converts a BSM error value to a string, generally by converting first to a
|
|
local error number and using the local
|
|
.Xr strerror 3
|
|
function, but will also work for errors that are not locally defined.
|
|
.Sh RETURN VALULES
|
|
On success,
|
|
.Fn au_bsm_to_errno
|
|
returns 0 and a converted error value; on failure, it returns -1 but does not
|
|
set
|
|
.Xr errno 2 .
|
|
.Pp
|
|
On success,
|
|
.Fn au_strerror
|
|
returns a pointer to an error string; on failure it will return
|
|
.Dv NULL .

.Sh HISTORY
|
|
.Fn au_bsm_to_errno
|
|
and
|
|
.Fn au_errno_to_bsm
|
|
were introduced in OpenBSM 1.1.

|
.Sh AUTHORS
|
|
These functions were implemented by
|
|
.An Robert Watson
|
|
under contract to Apple Inc.
|
|
.Pp
|
|
The Basic Security Module (BSM) interface to audit records and audit event
|
|
stream format were defined by Sun Microsystems.
|
|
.Sh BUGS
|
|
.Nm au_strerror
|
|
is unable to provide localized strings for errors not available in the local
|
|
operating system.
