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.

7a0a89d2cb Merge OpenBSM alpha 4 from OpenBSM vendor branch to head, both
contrib/openbsm (svn merge) and src/sys/{bsm,security/audit} (manual
merge).  Add libauditd build parts and add to auditd's linkage;
force libbsm to build before libauditd.

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.

- 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.

bc168a6cdd Vendor import TrustedBSD OpenBSM 1.0 alpha 14, with the following change
history notes since the last import:

OpenBSM 1.0 alpha 14

- 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.

4bd0c025f3 Vendor import TrustedBSD OpenBSM 1.0 alpha 12, with the following change
history notes since the last import:

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.

bb97b41819 Vendor import of OpenBSM 1.0 alpha 11, with the following change history
notes since the last import:

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.

506764c6f6 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.

3b97a967e1 Vendor branch import of TrustedBSD OpenBSM 1.0 alpha 5:
- Update install notes to indicate /etc files are to be installed manually.
- On systems without LOG_SECURITY, use LOG_AUTH.
- Convert to autoconf/automake in order to move to a more portable (not
  BSD-specific) build infrastructure, and more easy conditional building of
  components.  Currently, the primary feature loss is that automake does
  not have native support for manual symlinks.  This will be addressed in a
  future OpenBSM release.
- Add compat/queue.h, to be used on systems dated BSD queue macro libraries
  (as found on Linux).
- Rename CHANGELOG to HISTORY, as our change log doesn't follow some of the
  existing conventions for a CHANGELOG.
- Some private data structures moved from audit.h to audit_internal.h to
  prevent inappropriate use by applications and name space pollution.
- Improved detection and use of endian macros using autoconf.
- Avoid non-portable use of struct in6_addr, which is largely opaque.
- Avoid leaking BSD kernel socket related token code to user space in
  bsm_token.c.
- Teach System V IPC calls to look for Linux naming variations for certain
  struct ipc_perm fields.
- Test for audit system calls, and if not present, don't build
  bsm_wrappers.c, bsm_notify.c, audit(8), and auditd(8), which rely on
  those system calls.
- au_close() is not implemented on systems that don't have audit system
  calls, but au_close_buffer() is.
- Work around missing BSDisms in bsm_wrapper.c.
- Fix nested includes so including libbsm.h in an application on Linux
  picks up the necessary definitions.

ca0716f571 Initial vendor import of the TrustedBSD OpenBSM distribution, version
1.0 alpha 1, an implementation of the documented Sun Basic Security
Module (BSM) Audit API and file format, as well as local extensions to
support the Mac OS X and FreeBSD operating systems.  Also included are
command line tools for audit trail reduction and conversion to text,
as well as documentation of the commands, file format, and APIs.  This
distribution is the foundation for the TrustedBSD Audit implementation,
and is a pre-release.

This is the first in a series of commits to introduce support for
Common Criteria CAPP security event audit support.

This software has been made possible through the generous
contributions of Apple Computer, Inc., SPARTA, Inc., as well as
members of the TrustedBSD Project, including Wayne Salamon <wsalamon>
and Tom Rhodes <trhodes>.  The original OpenBSM implementation was
created by McAfee Research under contract to Apple Computer, Inc., as
part of their CC CAPP security evaluation.
