- 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.
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.

- 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.
