582434bd08 Fix some nasty race conditions in the VIA-CUDA driver that ended up preventing
my right mouse button and keyboard LEDs from working due to mangled
configuration packets. Fixed several other races and associated problems in the
main ADB stack that were exposed while fixing this.

eb67f31a1b Implement suspend/resume for mmc and mmcsd drivers.
Now it is possible to suspend/resume with inserted and active card.

To reinitialize card on resume and to detect card change while suspended,
implement bus rescan routines. It can also be used by controllers without
card presence detection signals or with multiple cards per slot support.

While there, cleanup msleep() usage. We have no any rights to exit without
"request done" signal from driver as it could lead to modify after free.

f45dd01002 Add a -L option to wc(1), for finger compatibility with the GNU
wc utility.  The -L option can be used to report the length of
the longest line wc has seen in one or more files.  It is
disabled by default, and wc uses the standard `-lwc'.

RTFREE_LOCKED() here.  This macro makes sure the reference count
on the route is being managed properly.  This elimates another

830d754d52 Code from the hack-session known as the IETF (and a
bit of debugging afterwards):
- Fix protection code for notification generation.
- Decouple associd from vtag
- Allow vtags to have less strigent requirements in non-uniqueness.
   o don't pre-hash them when you issue one in a cookie.
   o Allow duplicates and use addresses and ports to
     discriminate amongst the duplicates during lookup.
- Add support for the NAT draft draft-ietf-behave-sctpnat-00, this
  is still experimental and needs more extensive testing with the
  Jason Butt ipfw changes.
- Support for the SENDER_DRY event to get DTLS in OpenSSL working
  with a set of patches from Michael Tuexen (hopefully heading to OpenSSL soon).
- Update the support of SCTP-AUTH by Peter Lei.
- Use macros for refcounting.
- Fix MTU for UDP encapsulation.
- Fix reporting back of unsent data.
- Update assoc send counter handling to be consistent with endpoint sent counter.
- Fix a bug in PR-SCTP.
- Fix so we only send another FWD-TSN when a SACK arrives IF and only
  if the adv-peer-ack point progressed. However we still make sure
  a timer is running if we do have an adv_peer_ack point.
- Fix PR-SCTP bug where chunks were retransmitted if they are sent
  unreliable but not abandoned yet.

b1ff9c25b8 MfP4: Big read filter refactoring.
This is an attempt to eliminate a lot of redundant
code from the read ("decompression") filters by
changing them to juggle arbitrary-sized blocks
and consolidate reblocking code at a single point
in archive_read.c.

Along the way, I've changed the internal read/consume
API used by the format handlers to a slightly
different style originally suggested by des@.  It
does seem to simplify a lot of common cases.

The most dramatic change is, of course, to
archive_read_support_compression_none(), which
has just evaporated into a no-op as the blocking
code this used to hold has all been moved up
a level.

There's at least one more big round of refactoring
yet to come before the individual filters are as
straightforward as I think they should be...

2640173120 Unconditionally use locked addition of zero to tip of the stack for
memory barriers on i386. It works as a serialization instruction on
all IA32 CPUs.

Alternative solution of using {s,l,}fence requires run-time checking
of the presense of the corresponding SSE or SSE2 extensions, and
possible boot-time patching of the kernel text.

aeb325719a Several threads in a process may do vfork() simultaneously. Then, all
parent threads sleep on the parent' struct proc until corresponding
child releases the vmspace. Each sleep is interlocked with proc mutex of
the child, that triggers assertion in the sleepq_add(). The assertion
requires that at any time, all simultaneous sleepers for the channel use
the same interlock.

Silent the assertion by using conditional variable allocated in the
child. Broadcast the variable event on exec() and exit().

Since struct proc * sleep wait channel is overloaded for several
unrelated events, I was unable to remove wakeups from the places where
cv_broadcast() is added, except exec().

7e8cc2bd03 Some libstand/bootp.c extension (written by Danny Braniss, slightly
revised/modified by me) to store dhcp options into kenv variables,
so the information is available to the boot loader and can be used
to customize the boot process.

The change is totally unintrusive, essentially made of a single
function to be called while parsing a dhcp response, and a couple
of tables to classify options.  The values extracted from dhcp
options are stored in the kenv environment in one of these forms:

 + options whose name and type is known are saved as
        dhcp.name = value     (string, or number/ip addresses lists)

 + unknown options are assumed to be strings and saved as
        dhcp.option-NNN = "value"

 + options listed as '__INDIR' and sent on the wire as e.g.
        option unknown-252 "some.name=the actual value"
   are saved as
        some.name = "the actual value"

 + options listed as '__ILIST' and sent on the wire as e.g.
        option unknown-249 "a.b=foo bar; c.d= 123; e.f=done"
   are saved as multiple values
        a.b="foo bar"
        c.d="123"
        e.f="done"

As you can see there is quite a bit of flexibility on what can
be passed to the loader or the kernel.

For the time being the vendor-specific table is mostly disabled,
because there is no standard set of options for FreeBSD, and I don't
know all the pxe-specific vendor options.

Also, applications using libstand may live in memory-constrained
environments, so it makes sense to keep these tables as small as
possible, especially considering that one can generate arbitrary
name=value pairs using site-specific options of type __INDIR or
__ILIST (there are 4 __ILIST and 5 __INDIR in the table, numbered
246..249 and 250..254).

Actually, considering that probably 75% of the standard dhcp options
are totally useless, it might make sense to remove them as well.

75444a8590 When the SYSINIT() to load a module invokes the MOD_LOAD event successfully,
move that module to the head of the associated linker file's list of modules.
The end result is that once all the modules are loaded, they are sorted in
the reverse of their load order.  This causes the kernel linker to invoke
the MOD_QUIESCE and MOD_UNLOAD events in the reverse of the order that
MOD_LOAD was invoked.  This means that the ordering of MOD_LOAD events that
is set by the SI_* paramters to DECLARE_MODULE() are now honored in the same
order they would be for SYSUNINIT() for the MOD_QUIESCE and MOD_UNLOAD
events.
