- Add a new "qsize" parameter in audit_control and the getacqsize(3) API to
query it, allowing to set the kernel's maximum audit queue length.
- Add support to push a mapping between audit event names and event numbers
into the kernel (where supported) using new A_GETEVENT and A_SETEVENT
auditon(2) operations.
- Add audit event identifiers for a number of new (and not-so-new) FreeBSD
system calls including those for asynchronous I/O, thread management, SCTP,
jails, multi-FIB support, and misc. POSIX interfaces such as
posix_fallocate(2) and posix_fadvise(2).
- On operating systems supporting Capsicum, auditreduce(1) and praudit(1) now
run sandboxed.
- Empty "flags" and "naflags" fields are now permitted in audit_control(5).
Many thanks to Christian Brueffer for producing the OpenBSM release and
importing/tagging it in the vendor branch. This release will allow improved
auditing of a range of new FreeBSD functionality, as well as non-traditional
events (e.g., fine-grained I/O auditing) not required by the Orange Book or
Common Criteria.

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.

merge).

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.
contrib/openbsm (svn merge) and src/sys/{bsm,security/audit} (manual
merge). Hook up bsm_domain.c and bsm_socket_type.c to the libbsm
build along with man pages, add audit_bsm_domain.c and
audit_bsm_socket_type.c to the kernel environment.

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.
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.
