contrib/openbsm (svn merge) and src/sys/{bsm,security/audit} (manual
merge). Hook up bsm_domain.c and bsm_socket_type.c to the libbsm
build along with man pages, add audit_bsm_domain.c and
audit_bsm_socket_type.c to the kernel environment.

OpenBSM 1.1 alpha 5
- Stub libauditd(3) man page added.
- All BSM error number constants with BSM_ERRNO_.
- Interfaces to convert between local and BSM socket types and protocol
families have been added: au_bsm_to_domain(3), au_bsm_to_socket_type(3),
au_domain_to_bsm(3), and au_socket_type_to_bsm(3), along with definitions
of constants in audit_domain.h and audit_socket_type.h. This improves
interoperability by converting local constant spaces, which vary by OS, to
and from Solaris constants (where available) or OpenBSM constants for
protocol domains not present in Solaris (a fair number). These routines
should be used when generating and interpreting extended socket tokens.
- Fix build warnings with full gcc warnings enabled on most supported
platforms.
- Don't compile error strings into bsm_errno.c when building it in the kernel
environment.
- When started by launchd, use the label com.apple.auditd rather than
org.trustedbsd.auditd.
for jumbo frame.
o Nuke unneeded jlist lock which was used to protect jumbo buffer
management in local allocator.
o Added a new tunable hw.mskc.jumbo_disable to disable jumbo
frame support for the driver. The tunable could be set for
systems that do not need to use jumbo frames and it would
save (9K * number of Rx descriptors) bytes kernel memory.
o Jumbo buffer allocation failure is no longer critical error
for the operation of msk(4). If msk(4) encounter the allocation
failure it just disables jumbo frame support and continues to
work without your intervention.
Using local allocator had several drawbacks such as requirement of
large amount of continuous kernel memory and fixed (small) number
of available buffers. The need for large continuous memory resulted
in failure of loading driver with kldload on running systems.
Also small number of buffer used in local allocator showed poor
performance for some applications.
+ Remove a dead field of a struct. It serves no purpose anymore.
+ Remove a \n at the end of the format string of err(); the err()
function already adds a \n ;
+ remove many unnecessary casts which obfuscate the code.
This file has a huge number of indentation bugs, but I'd rather fix
them when/if we happen to modify the relevant parts of the code.

Add missing set frame data pointer call. The
function call was missed when zero copy was
introduced in UMASS.

Remove dependancy towards the USB config thread in
the USB serial core. Use USB process msignalling
instead. Saves a little memory and hopefully makes
the code more understandable.

Remove "vbus_interrupt" method from bus methods and use
a global function instead for the various drivers using it.
The reason for the removal is to simplify the code.

Reduce the number of callback processes to 4 per
USB controller. There are two rough categories:
1) Giant locked USB transfers.
2) Non-Giant locked USB transfers.
On a real system with many USB devices plugged in the
number of processes reported by "ps auxw | grep USBPROC"
was reduced from 40 to 18.

This change is about removing three fields from "struct usb2_xfer"
which can be reached from "struct usb2_xfer_root" instead and cleaning
up the code after this change. The fields are "xfer->udev",
"xfer->xfer_mtx" and "xfer->usb2_sc". In this process the following
changes were also made:
Rename "usb2_root" to "xroot" which is short for "xfer root".
Rename "priv_mtx" to "xfer_mtx" in USB core.
The USB_XFER_LOCK and USB_XFER_UNLOCK macros should only be used in
the USB core due to dependency towards "xroot". Substitute macros
for the real lock in two USB device drivers.

Factor out roothub process into the USB bus structure for
all USB controller drivers. Essentially I am trying to
save some processes on the root HUB and get away
from the config thread pradigm. There will be a follow up
commit where the root HUB control and interrupt callback
will be moved over to run from the roothub process.
Total win: 3 processes become 1 for every USB controller.

Initial version of ATMEGA USB device controller
driver. Has not been tested on real hardware yet.
The driver is based upon the AT91DCI driver.

- Callwheels traced via KTR_CALLOUT. Each CPU is assigned a callwheel
source. The events on this source are the execution of individual callout
routines. Each routine shows up as a green rectangle while it is executed
and the event details include the function pointer and argument.
- Locks traced via KTR_LOCK. Currently, each lock name is assigned an event
source (since the existing KTR_LOCK traces only include lock names and
not pointers). This does mean that if multiple locks of the same name are
manipulated, the source line for that name may be confusing. However, for
many cases this can be useful. Locks are blue when they are held and
purple when contested. The contention support is a bit weak due to
limitations in the rw_rlock() and mtx_lock_spin() logging messages
currently. I also have not added support for contention on lockmgr,
sx, or rmlocks yet. What is there now can be profitably used to examine
activity on Giant however.
- Expand the width of the event source names column a bit to allow for some
of the longer names of these new source types.
(threads, CPU load counters, etc.). Each source is tagged with a group
and an order similar to the SYSINIT SI_SUB_* and SI_ORDER_*. After
the file is parsed, all the sources are then sorted. Currently, the only
affects of this are that the CPU loads are now sorted by CPU ID (so
CPU 0 is always first). However, this makes it easier to add new types
of event sources in the future and have them all clustered together
instead of intertwined with threads.
- Python lists perform insertions at the tail much faster than insertions
at the head. For a trace that had a lot of events for a single event
source, the constant insertions of new events to the head of the
per-source event list caused a noticable slow down. To compensate,
append new events to the end of the list during parsing and then
reverse the list prior to drawing.
- Somewhere in the tkinter internals the coordinates of a canvas are
stored in a signed 32-bit integer. As a result, if an the box for
an event spans 2^31, it would actually end up having a negative
X offset at one end. The result was a single box that covered the
entire event source. Kris worked around this for some traces by
bumping up the initial ticks/pixel ratio from 1 to 10. However, a
divisor of 10 can still be too small for large tracefiles (e.g.
with 4 million entries). Instead of hardcoding the initial scaling
ratio, calculate it from the time span of the trace file.
- Add support for using the mouse wheel to scroll the graph window
up and down.
