02b199f158 Link ALTQ to the build and break with ABI for struct ifnet. Please recompile
your (network) modules as well as any userland that might make sense of
sizeof(struct ifnet).
This does not change the queueing yet. These changes will follow in a
seperate commit. Same with the driver changes, which need case by case
evaluation.

__FreeBSD_version bump will follow.

b8b3323469 Add a new driver to support IP over firewire. This driver is intended to
conform to the rfc2734 and rfc3146 standard for IP over firewire and
should eventually supercede the fwe driver. Right now the broadcast
channel number is hardwired and we don't support MCAP for multicast
channel allocation - more infrastructure is required in the firewire
code itself to fix these problems.

1da2ceea66 Get rid of UMA zones and instead allocate all ecb's up front and track them
in a TAILQ.  Re-arrange some of the ecb elements so that they can stay
stable through alloc/free cycles while the rest get bzero'd.

- Use the tag_id from the ecb rather than fro the ccb.  The latter is only
for target mode.

- Honor the ccb flags for tag_action when deciding whether to do a tagged
or untagged transaction.

- Re-arrange autosense completion so that it works correctly in failure
cases.

- Turn on the PI_TAG_ABLE flag so that CAM will send us tagged transactions.

This enables tagged queueing in the driver.

359fdba7a7 Missed directory in previous commit; need to hold SOCK_LOCK(so)
before calling sotryfree().

-- Body of earlier bulk commit this belonged with --

  Log:
  Extend coverage of SOCK_LOCK(so) to include so_count, the socket
  reference count:

  - Assert SOCK_LOCK(so) macros that directly manipulate so_count:
    soref(), sorele().

  - Assert SOCK_LOCK(so) in macros/functions that rely on the state of
    so_count: sofree(), sotryfree().

  - Acquire SOCK_LOCK(so) before calling these functions or macros in
    various contexts in the stack, both at the socket and protocol
    layers.

  - In some cases, perform soisdisconnected() before sotryfree(), as
    this could result in frobbing of a non-present socket if
    sotryfree() actually frees the socket.

  - Note that sofree()/sotryfree() will release the socket lock even if
    they don't free the socket.

6ef5ab3cb5 Add an additional queue which will be "owned by the driver". This allows to
rig a PREPEND macro for ALTQ as the POLL/DEQUEUE semantic is very bad in
terms of locking. We make this a full functional queue to allow "bulk
dequeue" which will further reduce the locking overhead (for non-altq
enabled devices). Drivers will access this via the following macros, which
will show up in <net/if_var.h> once we expose ALTQ to the build:

IFQ_DRV_DEQUEUE(ifq, m)	- takes a mbuf off the queue (driver queue first)
IFQ_DRV_PREPEND(ifq, m)	- pushes a mbuf back to the driver queue
IFQ_DRV_PURGE(ifq)	- drops all packets in both queues
IFQ_DRV_IS_EMPTY(ifq)	- checks for pending mbufs in either queue

One has to make sure that the first three are protected by a driver mutex.
At the moment most network drivers still require Giant, so this is not an
issue. Even those that have thier own mutex usually hold it in if_start and
the like, so this requirement is almost always satisfied.

This evolved from a discussion with Andrew Gallatin.

f6c0cce6d9 Introduce a mutex into struct sockbuf, sb_mtx, which will be used to
protect fields in the socket buffer.  Add accessor macros to use the
mutex (SOCKBUF_*()).  Initialize the mutex in soalloc(), and destroy
it in sodealloc().  Add addition, add SOCK_*() access macros which
will protect most remaining fields in the socket; for the time being,
use the receive socket buffer mutex to implement socket level locking
to reduce memory overhead.

5321c2a9b0 Check pending signals, if there is signal will be unblocked by
sigsuspend, thread shouldn't wait, in old code, it may be
ignored.
When a signal handler is invoked in sigsuspend, thread gets
two different signal masks, one is in thread structure,
sigprocmask() can retrieve it, another is in ucontext
which is a third parameter of signal handler, the former is
the result of sigsuspend mask ORed with sigaction's sa_mask
and current signal, the later is the mask in thread structure
before sigsuspend is called. After signal handler is called,
the mask in ucontext should be copied into thread structure,
and becomes CURRENT signal mask, then sigsuspend returns to
user code.

6d43605d86 FreeBSD-ify ALTQ:
- add locking
 - disable ALTQ3_COMPAT by default (do not remove the code to keep the diff
   towards KAME small)
 - put some more code under ALTQ3 conditional compilation as it should be
 - account for if_xname
 - some more minor compile fixes

As people started wondering:
The strange path layout "altq/altq" is there to avoid "-Isys/contrib" and
make it "-Isys/contrib/altq" instead, as we will need at least <altq/altq.h>
and <altq/if_altq.h> for kernel compilation.

The "freebsd4_..." in the privious commit is just the best tag name in the
KAME tree I could find to classify this in order to track its history. It
does *not* mean that this will go to 4-STABLE or anything of that kind.

a2f5f9a397 Import parts of the ALTQ framework from latest KAME snapshot (which is up to
HEAD at this point). This will not exactly live in a vendor branch, but have
the vendor backing to make it easier to exchange diffs.

This will be followed by a diff which takes most of the .c files off the
vendor branch in order to:
 - add locking
 - disable ALTQ3_COMPAT code (which is outdated and "un-lockable")

There is work in progress to refine the configuration API. Import this "as
is" now to have more exposure time before 5-STABLE.

This is only the import, it will be some more days until you will actually
be able to compile ALTQ support into your kernel so don't hold your breath.
HEADUPs will be posted on current@ and net@ before this is actually enabled.

d316f2cf4f Modify ip fw so that whenever UID or GID constraints exist in a
ruleset, the pcb is looked up once per ipfw_chk() activation.

This is done by extracting the required information out of the PCB
and caching it to the ipfw_chk() stack. This should greatly reduce
PCB looking contention and speed up the processing of UID/GID based
firewall rules (especially with large UID/GID rulesets).

Some very basic benchmarks were taken which compares the number
of in_pcblookup_hash(9) activations to the number of firewall
rules containing UID/GID based contraints before and after this patch.

The results can be viewed here:
