597df30e62 Import OpenBSM 1.1p1 from vendor branch to 8-CURRENT, populating
contrib/openbsm and a subset also imported into sys/security/audit.
This patch release addresses several minor issues:

- Fixes to AUT_SOCKUNIX token parsing.
- IPv6 support for au_to_me(3).
- Improved robustness in the parsing of audit_control, especially long
  flags/naflags strings and whitespace in all fields.
- Add missing conversion of a number of FreeBSD/Mac OS X errnos to/from BSM
  error number space.

a751bb7470 Vendor import of OpenBSM 1.1, which incorporates the following changes
since the last imported OpenBSM release:

OpenBSM 1.1

- Change auditon(2) parameters and data structures to be 32/64-bit architecture
  independent.  Add more information to man page about auditon(2) parameters.
- Add wrapper functions for auditon(2) to use legacy commands when the new
  commands are not supported.
- Add default for 'expire-after' in audit_control to expire trail files when
  the audit directory is more than 10 megabytes ('10M').
- Interface to convert between local and BSM fcntl(2) command values has been
  added:  au_bsm_to_fcntl_cmd(3) and au_fcntl_cmd_to_bsm(3), along with
  definitions of constants in audit_fcntl.h.
- A bug, introduced in OpenBSM 1.1 alpha 4, in which AUT_RETURN32 tokens
  generated by audit_submit(3) were improperly encoded has been fixed.
- Fix example in audit_submit(3) man page.  Also, make it clear that we want
  the audit ID as the argument.
- A new audit event class 'aa', for post-login authentication and
  authorization events, has been added.

4df4e33572 Merge OpenBSM 1.1 changes to the FreeBSD 8.x kernel:
- Add and use mapping of fcntl(2) commands to new BSM constant space.
- Adopt (int) rather than (long) arguments to a number of auditon(2)
  commands, as has happened in Solaris, and add compatibility code to
  handle the old comments.

Note that BSM_PF_IEEE80211 is partially but not fully removed, as the
userspace OpenBSM 1.1alpha5 code still depends on it.  Once userspace
is updated, I'll GCC the kernel constant.

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.

OpenBSM 1.1 alpha 5

- Stub libauditd(3) man page added.
- All BSM error number constants with BSM_ERRNO_.
- Interfaces to convert between local and BSM socket types and protocol
  families have been added: au_bsm_to_domain(3), au_bsm_to_socket_type(3),
  au_domain_to_bsm(3), and au_socket_type_to_bsm(3), along with definitions
  of constants in audit_domain.h and audit_socket_type.h.  This improves
  interoperability by converting local constant spaces, which vary by OS, to
  and from Solaris constants (where available) or OpenBSM constants for
  protocol domains not present in Solaris (a fair number).  These routines
  should be used when generating and interpreting extended socket tokens.
- Fix build warnings with full gcc warnings enabled on most supported
  platforms.
- Don't compile error strings into bsm_errno.c when building it in the kernel
  environment.
- When started by launchd, use the label com.apple.auditd rather than
  org.trustedbsd.auditd.

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.

  printed after the exec args/env tokens.
- Support for AUT_SOCKET_EX extended socket tokens, which describe a
  socket using a pair of IPv4/IPv6 and port tuples.
- OpenBSM BSM file header version bumped for 1.1 release.
- Deprecated Darwin constants, such as TRAILER_PAD_MAGIC, removed.

OpenBSM 1.1 alpha 2

- Include files in OpenBSM are now broken out into two parts: library builds
  required solely for user space, and system includes, which may also be
  required for use in the kernels of systems integrating OpenBSM.  Submitted
  by Stacey Son.
- Configure option --with-native-includes allows forcing the use of native
  include for system includes, rather than the versions bundled with OpenBSM.
  This is intended specifically for platforms that ship OpenBSM, have adapted
  versions of the system includes in a kernel source tree, and will use the
  OpenBSM build infrastructure with an unmodified OpenBSM distribution,
  allowing the customized system includes to be used with the OpenBSM build.
  Submitted by Stacey Son.
- Various strcpy()'s/strcat()'s have been changed to strlcpy()'s/strlcat()'s
  or asprintf().  Added compat/strlcpy.h for Linux.
- Remove compatibility defines for old Darwin token constant names; now only
  BSM token names are provided and used.
- Add support for extended header tokens, which contain space for information
  on the host generating the record.
- Add support for setting extended host information in the kernel, which is
  used for setting host information in extended header tokens.  The
  audit_control file now supports a "host" parameter which can be used by
  auditd to set the information; if not present, the kernel parameters won't
  be set and auditd uses unextended headers for records that it generates.

OpenBSM 1.1 alpha 1

- Add option to auditreduce(1) which allows users to invert sense of
  matching, such that BSM records that do not match, are selected.
- Fix bug in audit_write() where we commit an incomplete record in the
  event there is an error writing the subject token.  This was submitted
  by Diego Giagio.
- Build support for Mac OS X 10.5.1 submitted by Eric Hall.
- Fix a bug which resulted in host XML attributes not being arguments so
  that const strings can be passed as arguments to tokens.  This patch was
  submitted by Xin LI.
- Modify the -m option so users can select more then one audit event.
- For Mac OS X, added Mach IPC support for audit trigger messages.
- Fixed a bug in getacna() which resulted in a locking problem on Mac OS X.
- Added LOG_PERROR flag to openlog when -d option is used with auditd.
- AUE events added for Mac OS X Leopard system calls.
