OpenBSM 1.1 beta 1
- The filesz parameter in audit_control(5) now accepts suffixes: 'B' for
Bytes, 'K' for Kilobytes, 'M' for Megabytes, and 'G' for Gigabytes.
For legacy support no suffix defaults to bytes.
- Audit trail log expiration support added. It is configured in
audit_control(5) with the expire-after parameter. If there is no
expire-after parameter in audit_control(5), the default, then the audit
trail files are not expired and removed. See audit_control(5) for
more information.
- Change defaults in audit_control: warn at 5% rather than 20% free for audit
partitions, rotate automatically at 2mb, and set the default policy to
cnt,argv rather than cnt so that execve(2) arguments are captured if
AUE_EXECVE events are audited. These may provide more usable defaults for
many users.
- Use au_domain_to_bsm(3) and au_socket_type_to_bsm(3) to convert
au_to_socket_ex(3) arguments to BSM format.
- Fix error encoding AUT_IPC_PERM tokens.

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