notes since the last import:
OpenBSM 1.0 alpha 9
- Rename many OpenBSM-specific constants and API elements containing the
strings "BSM" and "bsm" to "AUDIT" and "audit", observing that this is true
for almost all existing constants and APIs.
- Instead of passing a per-instance cookie directly into all audit filter
APIs, pass in the audit filter daemon state pointer, which is then used by
the module using an audit_filter_{get,set}cookie() API. This will allow
future service APIs provided by the filter daemon to maintain their own
state -- for example, per-module preselection state.
OpenBSM 1.0 alpha 8
- Correct typo in definition of AUR_INT.
- Adopt OpenSolaris constant values for AUDIT_* configuration flags.
- Arguments to au_to_exec_args() and au_to_exec_env() no longer const.
- Add kernel versions of au_to_exec_args() and au_to_exec_env().
- Fix exec argument type that is printed for env strings from 'arg' to 'env'.
- New OpenBSM token version number assigned, constants added for other
commonly seen version numbers.
- OpenBSM-specific events assigned numbers in the 43xxx range to avoid future
collisions with Solaris. Darwin events renamed to AUE_DARWIN_foo, as they
are now deprecated numberings.
- autoconf now detects clock_gettime(), which is not available on Darwin.
- praudit output fixes relating to arg32 and arg64 tokens.
- Maximum record size updated to 64k-1 to match Solaris record size limit.
- Various style and comment cleanups in include files.
This is an MFC candidate to RELENG_6.

notes:
- Adopted Solaris-compatible format for subject32_ex and subject64_ex
tokens, which previously did not correctly implement variable length
address storage.
- Prefer inttypes.h to stdint.h; enhance queue.h detection to test for
TAILQ_FOREACH_SAFE(), which is present in recent BSD queue.h's, but not
older ones. OpenBSM now builds on some FreeBSD 4.x version.
- New event types for extended attributes, ACLs, and scheduling.

the CVS import, and suggest removing it for the real import, rather than
suggesting it for testing. This will hopefully prevent me (and others)
from making errors.

IANA's list aggrees with <netinet/ip_icmp.h>.
I've tried to do this in a way which is mostly consistent with
tcptraceroute and Debian's version of traceroute. However, sometimes
a letter is used twice by these versions, so I've gone with:

non-shared object, do not reserve space in .plt and .rela.plt
for regular symbols neither defined nor referenced in shared objects.
This is a backport of rev. 1.101 (sourceware.org repository) to
Binutils 2.15 which fixes the creation of bogus relocations in the
PLT of Firefox and Thunderbird binaries and which in turn caused
them to segfault in rtld(1). This is committed to the vendor branch
as it doesn't represent a local change but the original vendor fix
is from after elf_link_hash_flags was replaced with bitfields.

- 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.
