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.
The function pow() in libmp(3) clashes with pow(3) in libm. We could
rename this single function, but we can just take the same approach as
the Solaris folks did, which is to prefix all function names with mp_.
libmp(3) isn't really popular nowadays. I suspect not a single
application in ports depends on it. There's still a chance, so I've
increased the SHLIB_MAJOR and __FreeBSD_version.

alignment requirement, while rt_msghdr has a 4 byte alignment
requirement. The root cause is that if_msghdr has an struct if_data
which has an 8-byte alignment requirement due to a time_t that's
embedded in it. On MIPS, time_t is a 64-bit number, so must be 64-bit
aligned.
Since we don't access ifm_data.ifi_epoch, a simple cast is all that's
necessary here. It is likely the case that ifi_epoch should *NOT* be
a time_t because it is an uptime (time delta) an not an absolute time
since 1970. u_long is likely sufficient there since that gives an
uptime of 136 years will suffice for the foreseeable future.

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.

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.
1. separating L2 tables (ARP, NDP) from the L3 routing tables
2. removing as much locking dependencies among these layers as
possible to allow for some parallelism in the search operations
3. simplify the logic in the routing code,
The most notable end result is the obsolescent of the route
cloning (RTF_CLONING) concept, which translated into code reduction
in both IPv4 ARP and IPv6 NDP related modules, and size reduction in
struct rtentry{}. The change in design obsoletes the semantics of
RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland
applications such as "arp" and "ndp" have been modified to reflect
those changes. The output from "netstat -r" shows only the routing
entries.
Quite a few developers have contributed to this project in the
past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and
Andre Oppermann. And most recently:
- Kip Macy revised the locking code completely, thus completing
the last piece of the puzzle, Kip has also been conducting
active functional testing
- Sam Leffler has helped me improving/refactoring the code, and
provided valuable reviews
- Julian Elischer setup the perforce tree for me and has helped
me maintaining that branch before the svn conversion
- Instead of including protocol info in diffs, strip them before adding
deltatext and take this into account when applying the diff later.
- Don't use strlen when the string in the RCS file may contain garbage. This got
caught in the checksumming before, but was not fixed until now. Instead of
using strlen, pass the token length when adding log and text entries to a
delta. Add an extra length parameter to duptext() to record the token length.
- When adding new branches to a file, add them in at the tail instead of the
head of the list to get correct ordering when writing out.
- Input stream when diffing was opened twice.
- Don't expand keywords in diffs between deltas.
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.
- Handle the case where a repository may have been copied, and the symlinks have
not been preserved. CVSup removes the files and creates the symlinks, so
enable this behaviour in csup as well.
- While there, fix comments and style issues.
- Use internal xmalloc instead of malloc.
- Include missing header after warnings.
- Fix unneeded printouts.
- Fix a bug when checking the CO_NORSYNC flag.
- This also removes $FreeBSD$ from two now unmodifed source files
ncurses/tinfo/lib_raw.c and ncurses/tinfo/lib_baudrate.c

Some time ago I got some reports MPSAFE TTY broke telnetd(8). Even
though it turned out to be a different problem within the TTY code, I
spotted a small issue with telnetd(8). Instead of allocating PTY's using
openpty(3) or posix_openpt(2), it used its own PTY allocation routine.
This means that telnetd(8) still uses /dev/ptyXX-style devices.
I've also increased the size of line[]. Even though 16 should be enough,
we already use 13 bytes ("/dev/pts/999", including '\0'). 32 bytes gives
us a little more freedom.
Also enable -DSTREAMSPTY. Otherwise telnetd(8) strips the PTY's pathname
to the latest slash instead of just removing "/dev/" (e.g. /dev/pts/0 ->
0, instead of pts/0).

own purposes. To pull this off, it defines _KERNEL before including the
headers where these structures are defined. This leads to no end of
trouble when some of these headers, or other headers that they include,
change, as demonstrated by r180755.
The quick fix in this particular case is to define _WANT_FILE instead of
_KERNEL, conditional on __FreeBSD__. A better long-term fix is left as
an exercise to the reader.
The xgetpass() function pushes a cleanup entry for &osa, but then
attempts to flush the stack until an entry matching &sa. The two
object pointers do not match, so the stack is popped too much,
and then cleanup_until calls abort() when it unexpectedly hits
the bottom of the cleanup stack.

the patch from ISC for lib/bind9/check.c and deletion of unused

This version will by default randomize the UDP query source port
(and sequence number of course) for every query.
In order to take advantage of this randomization users MUST have an
appropriate firewall configuration to allow UDP queries to be sent and
answers to be received on random ports; and users MUST NOT specify a
port number using the query-source[-v6] options.
The avoid-v[46]-udp-ports options exist for users who wish to eliminate
certain port numbers from being chosen by named for this purpose. See
the ARM Chatper 6 for more information.
Also please note, this issue applies only to UDP query ports. A random
ephemeral port is always chosen for TCP queries.
This issue applies primarily to name servers whose main purpose is to
resolve random queries (sometimes referred to as "caching" servers, or
more properly as "resolving" servers), although even an "authoritative"
name server will make some queries, primarily at startup time.
All users of BIND are strongly encouraged to upgrade to the latest
version, and to utilize the source port randomization feature.
