merge).
OpenBSM history for imported revision below for reference.

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.

history notes since the last import:
OpenBSM 1.0 alpha 14
- Fix endian issues when processing IPv6 addresses for extended subject
and process tokens.
- gcc41 warnings clean.
- Teach audit_submit(3) about getaudit_addr(2).
- Add support for zonename tokens.
OpenBSM 1.0 alpha 13
- compat/clock_gettime.h now provides a compatibility implementation of
clock_gettime(), which fixes building on Mac OS X.
- Countless man page improvements, markup fixes, content fixs, etc.
- XML printing support via "praudit -x".
- audit.log.5 expanded to include additional BSM token types.
- Added encoding and decoding routines for process64_ex, process32_ex,
subject32_ex, header64, and attr64 tokens.
- Additional audit event identifiers for listen, mlockall/munlockall,
getpath, POSIX message queues, and mandatory access control.

notes since the last import:
OpenBSM 1.0 alpha 11
- Reclassify certain read/write operations as having no class rather than the
fr/fw class; our default classes audit intent (open) not operations (read,
write).
- Introduce AUE_SYSCTL_WRITE event so that BSD/Darwin systems can audit reads
and writes of sysctls as separate events. Add additional kernel
environment and jail events for FreeBSD.
- Break AUDIT_TRIGGER_OPEN_NEW into two events, AUDIT_TRIGGER_ROTATE_USER
(issued by the user audit(8) tool) and AUDIT_TRIGGER_ROTATE_KERNEL (issued
by the kernel audit implementation) so that they can be distinguished.
- Disable rate limiting of rotate requests; as the kernel doesn't retransmit
a dropped request, the log file will otherwise grow indefinitely if the
trigger is dropped.
- Improve auditd debugging output.
- Fix a number of threading related bugs in audit_control file reading
routines.
- Add APIs au_poltostr() and au_strtopol() to convert between text
representations of audit_control policy flags and the flags passed to
auditon(A_SETPOLICY) and retrieved from auditon(A_GETPOLICY).
- Add API getacpol() to return the 'policy:' entry from audit_control, an
extension to the Solaris file format to allow specification of policy
persistent flags.
- Update audump to print the audit_control policy field.
- Update auditd to read the audit_control policy field and set the kernel
policy to match it when configuring/reconfiguring. Remove the -s and -h
arguments as these policies are now set via the configuration file. If a
policy line is not found in the configuration file, continue with the
current default of setting AUDIT_CNT.
- Fix bugs in the parsing of large execve(2) arguments and environmental
variable tokens; increase maximum parsed argument and variable count.
- configure now detects strlcat(), used by policy-related functions.
- Reference token and record sample files added to test tree.

- Remove "audit" user example from audit_user, as it's not present on most
systems.
- Add cannot_audit() function non-Darwin systems that wraps auditon();
required by OpenSSH BSM support. Convert Darwin cannot_audit() into a
function rather than a macro.
- Library build fixed on Darwin following include file tweaks. The native
Darwin sys/audit.h conflicts with bsm/audit.h due to duplicate types, so
for now we force bsm_wrappers.c to not perform a nested include of
sys/audit.h.

1.0 alpha 1, an implementation of the documented Sun Basic Security
Module (BSM) Audit API and file format, as well as local extensions to
support the Mac OS X and FreeBSD operating systems. Also included are
command line tools for audit trail reduction and conversion to text,
as well as documentation of the commands, file format, and APIs. This
distribution is the foundation for the TrustedBSD Audit implementation,
and is a pre-release.
This is the first in a series of commits to introduce support for
Common Criteria CAPP security event audit support.
This software has been made possible through the generous
contributions of Apple Computer, Inc., SPARTA, Inc., as well as
members of the TrustedBSD Project, including Wayne Salamon <wsalamon>
and Tom Rhodes <trhodes>. The original OpenBSM implementation was
created by McAfee Research under contract to Apple Computer, Inc., as
part of their CC CAPP security evaluation.
