Merge OpenBSM 1.2-alpha3 from head to stable/9, upgrading from the previous
OpenBSM 1.1p2:

OpenBSM 1.2 alpha 3

- Various minor tweaks to the auditdistd build to make it fit the FreeBSD
build environment better.
- AUE_WAIT6 merged from FreeBSD 9.

OpenBSM 1.2 alpha 2

- auditdistd, a distributed audit trail management daemon, has now been
merged. This allows trail files to be securely and reliably synced from
audited hosts to an audit server, and employs TLS encryption. Where
available, it uses Capsicum to sandbox the service. This work was
contributed by Pawel Jakub Dawidek under sponsorship from the FreeBSD
Foundation.

OpenBSM 1.2 alpha 1

- Add Capsicum-related error numbers for FreeBSD: ENOTCAPABLE, ECAPMODE.
- Add Capsicum, process descriptor audit events for FreeBSD.
- Allow 0% minspace.
- Fixes from the clang static analyser.
- Fix expiration of trail files when the host parameter is used.
- Various typo fixes.
- Support for Solaris privilege and privilege set tokens.
- Documentation for getachost(), improvements for getacfilesz().
- Fix a directory descriptor leak that happened when audit trail partitions
filled.
- Support for more Linux distributions with a partial contemporary endian.h.
- Improved escaping of XML-encapsulated BSM.
- A variety of minor documentation, style, and functional.

A separate commit will merge build changes to enable auditdistd, etc.

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.
