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.

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.

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.

- Restore the behavior of printing the string/text specified while

- Synchronized audit event list to Solaris, picking up the *at(2) system call
definitions, now required for FreeBSD and Linux. Added additional events
for *at(2) system calls not present in Solaris.
- Bugs in auditreduce(8) fixed allowing partial date strings to be used in
filtering events.

Vendor import TrustedBSD OpenBSM 1.0 alpha 14, with the following change
history notes since the last import:

OpenBSM 1.0 alpha 14

- Fix endian issues when processing IPv6 addresses for extended subject
and process tokens.

- Teach audit_submit(3) about getaudit_addr(2).

- 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.

Vendor branch import of TrustedBSD OpenBSM 1.0 alpha 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.
