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.

3f3bb0d402 Merge OpenBSM 1.0 alpha 15 changes to src/sys/bsm:
- Synchronized audit event list to Solaris, picking up the *at(2) system call
  definitions, now required for FreeBSD and Linux.  Added additional events
  for *at(2) system calls not present in Solaris.

b63c567b6f Change $P4$ ID strings to P4 ID strings so that they are not auto-expanded
when integrated back into Perforce.  This avoids unnecessary conflicts
during the loopback of files maintained in Perforce.

a5081e077b Update src/sys/bsm include files to match OpenBSM (albeit with a
couple of FreeBSD-specific modifications that may be merged out
later).  These include files define the basic audit data
structures, types, and definitions use by the kernel, or shared
by the kernel and user space.

9b9f45231e Add a stub audit_kevents.h, which defines exactly one audit event:
AUE_NULL.  This is a place-holder to allow other audit infrastructure
to be introduced, such as an updated syscalls.master file format,
while the license on the real audit_kevents.h is fixed.
