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.
contrib/openbsm (svn merge) and src/sys/{bsm,security/audit} (manual
merge). Add libauditd build parts and add to auditd's linkage;
force libbsm to build before libauditd.

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.
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.
since the last import:
OpenBSM 1.0
- Fix bug in auditreduce(8) which resulted in a memory fault/crash when
the user specified an event name with -m.
- Remove AU_.* hard-coded audit class constants, as udit classes are now
entirely dynamically configured using /etc/security/audit_class.

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.

- 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.

- 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.

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.
