25122f5c5f Add ECAPMODE, "Not permitted in capability mode", a new kernel errno
constant to indicate that a system call (or perhaps an operation requested
via a system call) is not permitted for a capability mode process.

597df30e62 Import OpenBSM 1.1p1 from vendor branch to 8-CURRENT, populating
contrib/openbsm and a subset also imported into sys/security/audit.
This patch release addresses several minor issues:

- Fixes to AUT_SOCKUNIX token parsing.
- IPv6 support for au_to_me(3).
- Improved robustness in the parsing of audit_control, especially long
  flags/naflags strings and whitespace in all fields.
- Add missing conversion of a number of FreeBSD/Mac OS X errnos to/from BSM
  error number space.

c38898116a There is an optimization in chmod(1), that makes it not to call chmod(2)
if the new file mode is the same as it was before; however, this
optimization must be disabled for filesystems that support NFSv4 ACLs.
Chmod uses pathconf(2) to determine whether this is the case - however,
pathconf(2) always follows symbolic links, while the 'chmod -h' doesn't.

This change adds lpathconf(3) to make it possible to solve that problem
in a clean way.

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.

4df4e33572 Merge OpenBSM 1.1 changes to the FreeBSD 8.x kernel:
- Add and use mapping of fcntl(2) commands to new BSM constant space.
- Adopt (int) rather than (long) arguments to a number of auditon(2)
  commands, as has happened in Solaris, and add compatibility code to
  handle the old comments.

Note that BSM_PF_IEEE80211 is partially but not fully removed, as the
userspace OpenBSM 1.1alpha5 code still depends on it.  Once userspace
is updated, I'll GCC the kernel constant.

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

  expire-after parameter in audit_control(5), the default, then the audit
  trail files are not expired and removed.  See audit_control(5) for

- 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

  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

  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.

  between BSM error numbers (largely the Solaris definitions) and local
  errno(2) values for 32-bit and 64-bit return tokens.  This is required

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.

ffbcef5a42 Add support for extended header BSM tokens. Currently we use the
regular header tokens.  The extended header tokens contain an IP
or IPv6 address which makes it possible to identify which host an
audit record came from when audit records are centralized.

If the host information has not been specified, the system will
default to the old style headers.  Otherwise, audit records that
are created as a result of system calls will contain host information.

This implemented has been designed to be consistent with the Solaris
implementation.  Host information is set/retrieved using the A_GETKAUDIT
and A_SETKAUDIT auditon(2) commands.  These commands require that a
pointer to a auditinfo_addr_t object is passed.  Currently only IP and
IPv6 address families are supported.

The users pace bits associated with this change will follow in an
openbsm import.

e484af13ed When MPSAFE ttys were merged, a new BSM audit event identifier was
allocated for posix_openpt(2).  Unfortunately, that identifier
conflicts with other events already allocated to other systems in
OpenBSM.  Assign a new globally unique identifier and conform
better to the AUE_ event naming scheme.

This is a stopgap until a new OpenBSM import is done with the
correct identifier, so we'll maintain this as a local diff in svn
until then.

bc093719ca Integrate the new MPSAFE TTY layer to the FreeBSD operating system.
The last half year I've been working on a replacement TTY layer for the
FreeBSD kernel. The new TTY layer was designed to improve the following:

- Improved driver model:

  The old TTY layer has a driver model that is not abstract enough to
  make it friendly to use. A good example is the output path, where the
  device drivers directly access the output buffers. This means that an
  in-kernel PPP implementation must always convert network buffers into
  TTY buffers.

  If a PPP implementation would be built on top of the new TTY layer
  (still needs a hooks layer, though), it would allow the PPP
  implementation to directly hand the data to the TTY driver.

- Improved hotplugging:

  With the old TTY layer, it isn't entirely safe to destroy TTY's from
  the system. This implementation has a two-step destructing design,
  where the driver first abandons the TTY. After all threads have left
  the TTY, the TTY layer calls a routine in the driver, which can be
  used to free resources (unit numbers, etc).

  The pts(4) driver also implements this feature, which means
  posix_openpt() will now return PTY's that are created on the fly.

- Improved performance:

  One of the major improvements is the per-TTY mutex, which is expected
  to improve scalability when compared to the old Giant locking.
  Another change is the unbuffered copying to userspace, which is both
  used on TTY device nodes and PTY masters.

Upgrading should be quite straightforward. Unlike previous versions,
existing kernel configuration files do not need to be changed, except
when they reference device drivers that are listed in UPDATING.

while the license on the real audit_kevents.h is fixed.
