d9af45c4c8 Vendor import of OpenBSM 1.0 alpha 7, with the following change history
notes:

- Adopted Solaris-compatible format for subject32_ex and subject64_ex
  tokens, which previously did not correctly implement variable length
  address storage.
- Prefer inttypes.h to stdint.h; enhance queue.h detection to test for
  TAILQ_FOREACH_SAFE(), which is present in recent BSD queue.h's, but not
  older ones.  OpenBSM now builds on some FreeBSD 4.x version.
- New event types for extended attributes, ACLs, and scheduling.

506764c6f6 Vendor branch import of TrustedBSD OpenBSM 1.0 alpha 6:
- Use AU_TO_WRITE and AU_NO_TO_WRITE for the 'keep' argument to au_close();
  previously we used hard-coded 0 and 1 values.
- Add man page for au_open(), au_write(), au_close(), and
  au_close_buffer().
- Support a more complete range of data types for the arbitrary data token:
  add AUR_CHAR (alias to AUR_BYTE), remove AUR_LONG, add AUR_INT32 (alias
  to AUR_INT), add AUR_INT64.
- Add au_close_token(), which allows writing a single token_t to a memory
  buffer.  Not likely to be used much by applications, but useful for
  writing test tools.
- Modify au_to_file() so that it accepts a timeval in user space, not just
  kernel -- this is not a Solaris BSM API so can be modified without
  causing compatibility issues.
- Define a new API, au_to_header32_tm(), which adds a struct timeval
  argument to the ordinary au_to_header32(), which is now implemented by
  wrapping au_to_header32_tm() and calling gettimeofday().  #ifndef KERNEL
  the APIs that invoke gettimeofday(), rather than having a variable
  definition.  Don't try to retrieve time zone information using
  gettimeofday(), as it's not needed, and introduces possible failure
  modes.
- Don't perform byte order transformations on the addr/machine fields of
  the terminal ID that appears in the process32/subject32 tokens.  These
  are assumed to be IP addresses, and as such, to be in network byte
  order.
- Universally, APIs now assume that IP addresses and ports are provided
  in network byte order.  APIs now generally provide these types in
  network byte order when decoding.
- Beginnings of an OpenBSM test framework can now be found in openbsm/test.
  This code is not built or installed by default.
- auditd now assigns more appropriate syslog levels to its debugging and
  error information.
- Support for audit filters introduced: audit filters are dynamically
  loaded shared objects that run in the context of a new daemon,
  auditfilterd.  The daemon reads from an audit pipe and feeds both BSM and
  parsed versions of records to shared objects using a module API.  This
  will provide a framework for the writing of intrusion detection services.
- New utility API, audit_submit(), added to capture common elements of audit
  record submission for many applications.

3b97a967e1 Vendor branch import of TrustedBSD OpenBSM 1.0 alpha 5:
- Update install notes to indicate /etc files are to be installed manually.
- On systems without LOG_SECURITY, use LOG_AUTH.
- Convert to autoconf/automake in order to move to a more portable (not
  BSD-specific) build infrastructure, and more easy conditional building of
  components.  Currently, the primary feature loss is that automake does
  not have native support for manual symlinks.  This will be addressed in a
  future OpenBSM release.
- Add compat/queue.h, to be used on systems dated BSD queue macro libraries
  (as found on Linux).
- Rename CHANGELOG to HISTORY, as our change log doesn't follow some of the
  existing conventions for a CHANGELOG.
- Some private data structures moved from audit.h to audit_internal.h to
  prevent inappropriate use by applications and name space pollution.
- Improved detection and use of endian macros using autoconf.
- Avoid non-portable use of struct in6_addr, which is largely opaque.
- Avoid leaking BSD kernel socket related token code to user space in
  bsm_token.c.
- Teach System V IPC calls to look for Linux naming variations for certain
  struct ipc_perm fields.
- Test for audit system calls, and if not present, don't build
  bsm_wrappers.c, bsm_notify.c, audit(8), and auditd(8), which rely on
  those system calls.
- au_close() is not implemented on systems that don't have audit system
  calls, but au_close_buffer() is.
- Work around missing BSDisms in bsm_wrapper.c.
- Fix nested includes so including libbsm.h in an application on Linux
  picks up the necessary definitions.

f4e380b0ce CVS import OpenBSM 1.0 alpha 4:
- 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.

23bf6e2091 Vendor branch import of OpenBSM 1.0 alpha 3:
- Man page formatting, cross reference, mlinks, and accuracy improvements.
- auditd and tools now compile and run on FreeBSD/arm.
- auditd will now fchown() the trail file to the audit review group, if
  defined at compile-time.
- Added AUE_SYSARCH for FreeBSD.
- Definition of AUE_SETFSGID fixed for Linux.

ca0716f571 Initial vendor import of the TrustedBSD OpenBSM distribution, version
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.
