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.

.Dt AU_BSM_TO_DOMAIN 3
.Os
.Sh NAME
.Nm au_bsm_to_domain ,
.Nm au_domain_to_bsm
.Nd "convert between BSM and local protocol domains"
.Sh LIBRARY
.Lb libbsm
.Sh SYNOPSIS
.In bsm/libbsm.h
.Ft int
.Fn au_bsm_to_domain "u_short bsm_domain" "int *local_domainp"
.Ft u_short
.Fn au_domain_to_bsm "int local_domain"
.Sh DESCRIPTION
These interfaces may be used to convert between the local and BSM protocol
domains.
The
.Fn au_bsm_to_domain
function accepts a BSM domain,
.Fa bsm_domain ,
and converts it to a local domain, such as those passed to
.Xr socket 2 ,
that will be stored in the integer pointed to by
.Fa local_domainp
if successful.
This call will fail if the BSM domain cannot be mapped into a local domain,
which may occur if the socket token was generated on another operating
system.
.Pp
The
.Fn au_domain_to_bsm
function accepts a local domain, and returns the BSM domain for it.
This call cannot fail, and instead returns a BSM domain indicating to a later
decoder that the domain could not be encoded.
.Sh RETURN VALULES
On success,
.Fn au_bsm_to_domain
returns 0 and a converted domain; on failure, it returns -1 but does not set
.Xr errno 2 .
.Sh SEE ALSO
.Xr au_bsm_to_socket_type 3 ,
.Xr au_socket_type_to_bsm 3 ,
.Xr au_to_socket_ex 3 ,
.Xr libbsm 3
.Sh HISTORY
.Fn au_bsm_to_domain
and
.Fn au_domain_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.
