contrib/openbsm (svn merge) and sys/{bsm,security/audit} (manual merge).
- Add OpenBSM contrib tree to include paths for audit(8) and auditd(8).
- Merge support for new tokens, fixes to existing token generation to
audit_bsm_token.c.
- Synchronize bsm includes and definitions.

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.

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 9
- Rename many OpenBSM-specific constants and API elements containing the
strings "BSM" and "bsm" to "AUDIT" and "audit", observing that this is true
for almost all existing constants and APIs.
- Instead of passing a per-instance cookie directly into all audit filter
APIs, pass in the audit filter daemon state pointer, which is then used by
the module using an audit_filter_{get,set}cookie() API. This will allow
future service APIs provided by the filter daemon to maintain their own
state -- for example, per-module preselection state.
OpenBSM 1.0 alpha 8
- Correct typo in definition of AUR_INT.
- Adopt OpenSolaris constant values for AUDIT_* configuration flags.
- Arguments to au_to_exec_args() and au_to_exec_env() no longer const.
- Add kernel versions of au_to_exec_args() and au_to_exec_env().
- Fix exec argument type that is printed for env strings from 'arg' to 'env'.
- New OpenBSM token version number assigned, constants added for other
commonly seen version numbers.
- OpenBSM-specific events assigned numbers in the 43xxx range to avoid future
collisions with Solaris. Darwin events renamed to AUE_DARWIN_foo, as they
are now deprecated numberings.
- autoconf now detects clock_gettime(), which is not available on Darwin.
- praudit output fixes relating to arg32 and arg64 tokens.
- Maximum record size updated to 64k-1 to match Solaris record size limit.
- Various style and comment cleanups in include files.
This is an MFC candidate to RELENG_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.
