FYI, I have just completed the merge of the OpenBSM 1.0 alpha 12 release to
RELENG_6. This is very likely the version of OpenBSM that will ship in
6.2-RELEASE. Most of the changes are bug fixes based on the feedback from
users (thanks!), but there are a couple of minor features. The four important
ones are:
- extensions to the /etc/security/audit_control file format to allow
specification of policy flags persistently there (such as the argv and envv
flags, which control the level of auditing for execve(2) events),
- the filesz paramater, which controls automated rotation of the audit log
based on file size, and
- A tweak to the audit_user(5) invocation event set to include an event for
audit log rotate. This makes it easy to do things like configure automatic
compression of archiving of terminated trails, etc.
- auditreduce can now filter paths using regular expressions, not just simple
string matching.
Please report any bugs/problems. The above/below changes will appear in
6.2-BETA2, and should already be available via cvsup.
Thanks,

Log:
Merge OpenBSM 1.0 alpha 12 from HEAD to RELENG_6, which includes a broad
range of bug fixes made as a result of reports on 6.x, as well as some
minor enhancements:
OpenBSM 1.0 alpha 12
- Correct bug in auditreduce which prevented the -c option from working
correctly when the user specifies to process successful or failed events.
The problem stemmed from not having access to the return token at the time
the initial preselection occurred, but now a second preselection process
occurs while processing the return token.
- getacfilesz(3) API added to read new audit_control(5) filesz setting,
which auditd(8) now sets the kernel audit trail rotation size to.
- auditreduce(1) now uses stdin if no file names are specified on the command
line; this was the documented behavior previously, but it was not
implemented. Be more specific in auditreduce(1)'s examples section
about
what might be done with the output of auditreduce.
- Add audit_warn(5) closefile event so that administrators can hook
termination of an audit trail file. For example, this might be used to
compress the trail file after it is closed.
- auditreduce(1) now uses regular expressions for pathname matching. Users
can
now supply one or more (comma delimited) regular expressions for searching
the pathnames. If one of the regular expressions is prefixed with a tilde
(~), and a path matches, it will be excluded from the search results.
OpenBSM 1.0 alpha 11
- Reclassify certain read/write operations as having no class rather than the
fr/fw class; our default classes audit intent (open) not operations (read,
write).
- Introduce AUE_SYSCTL_WRITE event so that BSD/Darwin systems can audit reads
and writes of sysctls as separate events. Add additional kernel
environment and jail events for FreeBSD.
- Break AUDIT_TRIGGER_OPEN_NEW into two events, AUDIT_TRIGGER_ROTATE_USER
(issued by the user audit(8) tool) and AUDIT_TRIGGER_ROTATE_KERNEL (issued
by the kernel audit implementation) so that they can be distinguished.
- Disable rate limiting of rotate requests; as the kernel doesn't
retransmit
a dropped request, the log file will otherwise grow indefinitely if the
trigger is dropped.
- Improve auditd debugging output.
- Fix a number of threading related bugs in audit_control file reading
routines.
- Add APIs au_poltostr() and au_strtopol() to convert between text
representations of audit_control policy flags and the flags passed to
auditon(A_SETPOLICY) and retrieved from auditon(A_GETPOLICY).
- Add API getacpol() to return the 'policy:' entry from
audit_control, an
extension to the Solaris file format to allow specification of policy
persistent flags.
- Update audump to print the audit_control policy field.
- Update auditd to read the audit_control policy field and set the kernel
policy to match it when configuring/reconfiguring. Remove the -s and -h
arguments as these policies are now set via the configuration file. If a
policy line is not found in the configuration file, continue with the
current default of setting AUDIT_CNT.
- Fix bugs in the parsing of large execve(2) arguments and environmental
variable tokens; increase maximum parsed argument and variable count.
- configure now detects strlcat(), used by policy-related functions.
- Reference token and record sample files added to test tree.
