68e8e04e93 Update 802.11 wireless support:
o major overhaul of the way channels are handled: channels are now
  fully enumerated and uniquely identify the operating characteristics;
  these changes are visible to user applications which require changes
o make scanning support independent of the state machine to enable
  background scanning and roaming
o move scanning support into loadable modules based on the operating
  mode to enable different policies and reduce the memory footprint
  on systems w/ constrained resources
o add background scanning in station mode (no support for adhoc/ibss
  mode yet)
o significantly speedup sta mode scanning with a variety of techniques
o add roaming support when background scanning is supported; for now
  we use a simple algorithm to trigger a roam: we threshold the rssi
  and tx rate, if either drops too low we try to roam to a new ap
o add tx fragmentation support
o add first cut at 802.11n support: this code works with forthcoming
  drivers but is incomplete; it's included now to establish a baseline
  for other drivers to be developed and for user applications
o adjust max_linkhdr et. al. to reflect 802.11 requirements; this eliminates
  prepending mbufs for traffic generated locally
o add support for Atheros protocol extensions; mainly the fast frames
  encapsulation (note this can be used with any card that can tx+rx
  large frames correctly)
o add sta support for ap's that beacon both WPA1+2 support
o change all data types from bsd-style to posix-style
o propagate noise floor data from drivers to net80211 and on to user apps
o correct various issues in the sta mode state machine related to handling
  authentication and association failures
o enable the addition of sta mode power save support for drivers that need
  net80211 support (not in this commit)
o remove old WI compatibility ioctls (wicontrol is officially dead)
o change the data structures returned for get sta info and get scan
  results so future additions will not break user apps
o fixed tx rate is now maintained internally as an ieee rate and not an
  index into the rate set; this needs to be extended to deal with
  multi-mode operation
o add extended channel specifications to radiotap to enable 11n sniffing

Drivers:
o ath: add support for bg scanning, tx fragmentation, fast frames,
       dynamic turbo (lightly tested), 11n (sniffing only and needs
       new hal)
o awi: compile tested only
o ndis: lightly tested
o ipw: lightly tested
o iwi: add support for bg scanning (well tested but may have some
       rough edges)
o ral, ural, rum: add suppoort for bg scanning, calibrate rssi data
o wi: lightly tested

This work is based on contributions by Atheros, kmacy, sephe, thompsa,
mlaier, kevlo, and others.  Much of the scanning work was supported by
Atheros.  The 11n work was supported by Marvell.

f194524fb1 Fix a case in tcp_do_segment() where tcp_update_sack_list() would
be called with an incorrect segment end value.  tcp_reass() may
trim segments when they overlap with already existing ones in the
reassembly queue.  Instead of saving the segment end value before
the call to tcp_reass() compute it on the fly based on the effective
segment length afterwards.

This bug was not really problematic as no information got lost and
the eventual SACK information computation was correct nontheless.

9cd40e64b4 Now pam_nologin(8) will provide an account management function
instead of an authentication function.  There are a design reason
and a practical reason for that.  First, the module belongs in
account management because it checks availability of the account
and does no authentication.  Second, there are existing and potential
PAM consumers that skip PAM authentication for good or for bad.
E.g., sshd(8) just prefers internal routines for public key auth;
OTOH, cron(8) and atrun(8) do implicit authentication when running
a job on behalf of its owner, so their inability to use PAM auth
is fundamental, but they can benefit from PAM account management.

Document this change in the manpage.

Modify /etc/pam.d files accordingly, so that pam_nologin.so is listed
under the "account" function class.

Bump __FreeBSD_version (mostly for ports, as this change should be
invisible to C code outside pam_nologin.)

6ceeb2bc16 Work around a firmware bug in the HP rx2660, where in ACPI an I/O port
is really a memory mapped I/O address. The bug is in the GAS that
describes the address and in particular the SpaceId field. The field
should not say the address is an I/O port when it clearly is not.

With an additional check for the IA64_BUS_SPACE_IO case in the bus
access functions, and the fact that I/O ports pretty much not used
in general on ia64, make the calculation of the I/O port address a
function. This avoids inlining the work-around into every driver,
and also helps reduce overall code bloat.

11752d88a2 Add a new physical memory allocator. However, do not yet connect it
to the build.

This allocator uses a binary buddy system with a twist.  First and
foremost, this allocator is required to support the implementation of
superpages.  As a side effect, it enables a more robust implementation
of contigmalloc(9).  Moreover, this reimplementation of
contigmalloc(9) eliminates the acquisition of Giant by
contigmalloc(..., M_NOWAIT, ...).

The twist is that this allocator tries to reduce the number of TLB
misses incurred by accesses through a direct map to small, UMA-managed
objects and page table pages.  Roughly speaking, the physical pages
that are allocated for such purposes are clustered together in the
physical address space.  The performance benefits vary.  In the most
extreme case, a uniprocessor kernel running on an Opteron, I measured
an 18% reduction in system time during a buildworld.

This allocator does not implement page coloring.  The reason is that
superpages have much the same effect.  The contiguous physical memory
allocation necessary for a superpage is inherently colored.

Finally, the one caveat is that this allocator does not effectively
support prezeroed pages.  I hope this is temporary.  On i386, this is
a slight pessimization.  However, on amd64, the beneficial effects of
the direct-map optimization outweigh the ill effects.  I speculate
that this is true in general of machines with a direct map.

A change to dconschat(8) will follow so that it can bomb

Though this method is just a hack and far from perfection,
it should be useful if you don't want to go machine room

9953c34ca6 Poll bus resets on FireWire while kdb/gdb is active.
Now, it's safe to call the fwohci interrupt(polling) routine while ddb/gdb
is active. After this change, a dcons connnection over FireWire can survive
bus resets even in kernel debugger.

This means that it is not too late to plug a FireWire cable after a panic
to investigate the problem.

Actually there is a small window(between a jump to kernel from loader and
initialization of dcons_crom) in which no one can take care of a bus reset.
Except that window, firewire console should keep working
from loader to reboot even with a panic and a bus reset.

f545763cbd Eliminate pmap_install(), which was used to wrap pmap_switch() and
grab sched_lock. This would serialize calls to pmap_switch from
cpu_switch(). With the introduction of thread_lock, this is not
possible anymore, because thread_lock is not a single lock. It
varies.  Secondly and most importantly, it's not needed at all. The
only requirement for pmap_switch() is that it's not preempted
while in the middle of updating the CPU and PCPU. In other words,
it's a critical region. No locking required.

   each architecture.  This also allows the scheduler to use any locking it
   may want to.
 - Use the thread_lock() rather than sched_lock when preempting.
 - The scheduler lock is not required to synchronize release_aps.

2502c107ba Commit 3/14 of sched_lock decomposition.
- Add a per-turnstile spinlock to solve potential priority propagation
   deadlocks that are possible with thread_lock().
 - The turnstile lock order is defined as the exact opposite of the
   lock order used with the sleep locks they represent.  This allows us
   to walk in reverse order in priority_propagate and this is the only
   place we wish to multiply acquire turnstile locks.
 - Use the turnstile_chain lock to protect assigning mutexes to turnstiles.
 - Change the turnstile interface to pass back turnstile pointers to the
   consumers.  This allows us to reduce some locking and makes it easier
   to cancel turnstile assignment while the turnstile chain lock is held.

- Adapt sleepqueues to the new thread_lock() mechanism.
 - Delay assigning the sleep queue spinlock as the thread lock until after
   we've checked for signals.  It is illegal for a thread to return in
   mi_switch() with any lock assigned to td_lock other than the scheduler
   locks.
 - Change sleepq_catch_signals() to do the switch if necessary to simplify
   the callers.
 - Simplify timeout handling now that locking a sleeping thread has the
   side-effect of locking the sleepqueue.  Some previous races are no
   longer possible.

7b20fb19fb Commit 1/14 of sched_lock decomposition.
- Move all scheduler locking into the schedulers utilizing a technique
   similar to solaris's container locking.
 - A per-process spinlock is now used to protect the queue of threads,
   thread count, suspension count, p_sflags, and other process
   related scheduling fields.
 - The new thread lock is actually a pointer to a spinlock for the
   container that the thread is currently owned by.  The container may
   be a turnstile, sleepqueue, or run queue.
 - thread_lock() is now used to protect access to thread related scheduling
   fields.  thread_unlock() unlocks the lock and thread_set_lock()
   implements the transition from one lock to another.
 - A new "blocked_lock" is used in cases where it is not safe to hold the
   actual thread's lock yet we must prevent access to the thread.
 - sched_throw() and sched_fork_exit() are introduced to allow the
   schedulers to fix-up locking at these points.
 - Add some minor infrastructure for optionally exporting scheduler
   statistics that were invaluable in solving performance problems with
   this patch.  Generally these statistics allow you to differentiate
   between different causes of context switches.

041b706b2f Despite several examples in the kernel, the third argument of
sysctl_handle_int is not sizeof the int type you want to export.
The type must always be an int or an unsigned int.

Remove the instances where a sizeof(variable) is passed to stop
people accidently cut and pasting these examples.

In a few places this was sysctl_handle_int was being used on 64 bit
types, which would truncate the value to be exported.  In these
cases use sysctl_handle_quad to export them and change the format
to Q so that sysctl(1) can still print them.

5be25877a1 Add in a couple of things:
-	In the ioctl path let command get queued up and return
	when complete _without_ blocking the driving waiting for
	the response.  This way the driver doesn't "lock up" for
	~30s during a flash command.  Submitted by scottl.
      -	Add a guard so that if a DCMD of 0 is sent down the ioctl
	path don't send it to the controller.  Return with a
	status of OK.  This is a little strange since MegaCli
	doesn't seem to like something and will issue some DCMD
	of 0.  This doesn't happen under Linux.  So the emulation
	needs to be improved but I'm not sure what.  Another strange
	thing is that when a DCMD of 0 gets issued under i386 the
	controller returns OK but in amd64 the context is messed
	up.
      -	Add a guard so the context has to be with-in the legal
	limit so we get a reasonable error assertion versus random
	panic.

It's going to be a challenge to figure out why MegaCli is not totally
happy and then sends some bogus commands.  This means that flashing
firmware via the Linux tool won't work since it generates a DCMD of
0 when it should be opening the firmware for a flash update.  Without
this problem flashing works fine.  This means there is no publicly
available tool to upgrade the RAID firmware under FreeBSD right now.

include the SCSI pass-through changes.

12fb0330d8 o Implemented Rx/Tx checksum offload. The simple checksum logic in
GEMs is unable to discriminate UDP from TCP packets such that
  it can generate 0x0000 checksum value for the UDP datagram. So the
  UDP checksum offload was disabled by default. You can enable it
  by setting link0 flag with ifconfig(8).
o bus_dma(9) clean up. It now correctly set number of required DMA
  segments/size and removed incorrect use of BUS_DMA_ALLOCNOW flag
  in static allocations done via bus_dmamem_alloc(9).
o Implemented ALTQ(9) support.
o Implemented Tx side bus_dmamap_load_mbuf_sg(9) which can remove
  several book keeping chores orginated from call-back mechanism.
  Therefore gem_txdma_callback() was removed and its functionality
  was reimplemented in gem_load_txmbuf().
o Don't set GEM_TD_START_OF_PACKET flag until all remaining mbuf
  chains are set. I think it was a long standing bug and it caused
  fluctuating interrupts/CPU usage patterns while netperf test
  is in progress. Previously it seems that we race with the device.
  Because I don't have a documentation for GEM I'm not sure this is
  correct but almost all other documentations I have stated this
  implications on setting SOP mark in descriptor ring(e.g. hme(4)).
o Borrowed gem_defrag() from ath(4) which is supposed to be much
  faster than m_defrag(9) since it's not need to defrag all
  mbuf chains.
o gem_load_txmbuf() was changed to allow passed mbuf chains to free.
  Caller of gem_load_txmbuf() correctly handles freed mbuf chains.
o In gem_start_locked(), added checks for availability of Tx
  descriptors before trying to load DMA maps which could save CPU
  cycles when number of available descriptors are low. Also, simplyfy
  IFF_DRV_OACTIVE detection logic.
o Removed hard-coded function names in CTR macros and replaced it
  with __func__.
o Moved statistics counter register access to gem_tick() to reduce
  number of PCI bus accesses. There is no reason to update statistics
  counters in interrupt handler.
o Removed unnecessary call of gem_start_locked() in gem_ioctl().

35440dd3e9 AcpiAcquireGlobalLock() can sometimes sleep if the mutex is contested.
The global lock is a memory region shared with the BIOS and thus
has some strange behavior like the fact that the sleep is 1 ms max.
We use standard mutexes to synchronize with the SCI so acquiring
the global lock after locking the mutex resulted in a witness
warning.

To deal with this for now, acquire the global lock before all other
locks, similar to Giant.  This should fix the witness "sleeping
with mutex held" issue on boot that occurred after the last ACPI-CA
import.  In the future, we hope to move to the new mutex interface
in ACPI-CA instead of the pseudo-semaphore version we have now.

ad21a36485 - Take out the broken table-id concept. Panda Routers have a M-VRF
concept that is NOT well thought out for a multi-homed transport
  protocol. So the useless table-id entries passed around need to

1c4bcd050a - Move rusage from being per-process in struct pstats to per-thread in
td_ru.  This removes the requirement for per-process synchronization in
   statclock() and mi_switch().  This was previously supported by
   sched_lock which is going away.  All modifications to rusage are now
   done in the context of the owning thread.  reads proceed without locks.
 - Aggregate exiting threads rusage in thread_exit() such that the exiting
   thread's rusage is not lost.
 - Provide a new routine, rufetch() to fetch an aggregate of all rusage
   structures from all threads in a process.  This routine must be used
   in any place requiring a rusage from a process prior to it's exit.  The
   exited process's rusage is still available via p_ru.
 - Aggregate tick statistics only on demand via rufetch() or when a thread
   exits.  Tick statistics are kept in the thread and protected by sched_lock
   until it exits.

4f3349076d Couple of the fixes needed revising. The ICH8 autoneg was still broken,
this change both simplifies the code and plugs a hole where the devise
was reset without keeping the management controller at bay :) Second,
the 82571 LAA reset problem was incomplete, this addition is necessary.

3401f2c1df In some particular cases (like in pccard and pccbb), the real device
handler is wrapped in a couple of functions - a filter wrapper and an
ithread wrapper. In this case (and just in this case), the filter
wrapper could ask the system to schedule the ithread and mask the
interrupt source if the wrapped handler is composed of just an ithread
handler: modify the "old" interrupt code to make it support
this situation, while the "new" interrupt code is already ok.

bba4862c64 Last major commit and updates for RELENG_7:
- Rework the entire pcm_channel structure:
  * Remove rarely used link placeholder, instead, make each pcm_channel
    as head/link of each own/each other. Unlock - Lock sequence due to
    sleep malloc has been reduced.
  * Implement "busy" queue which will contain list of busy/active
    channels. This greatly reduce locking contention for example while
    servicing interrupt for hardware with many channels or when virtual
    channels reach its 256 peak channels.

- So I heard you like v chan ... O RLY?
  Welcome to Virtual **Record** Channels (vrec, rec vchans, vchans for
  recording, Rec-Chan, you decide), the ultimate solutions for your
  nagging O_RDWR full-duplex wannabe (note: flash plugins) monopolizing
  single record channel causing EBUSY.  Vrec works exactly like Vchans
  (or, should I rename it to "Vplay" :) , except that it operates on the
  opposite direction (recording). Up to 256 vrecs (like vchans) are
  possible.

  Notes:
   * Relocate dev.pcm.%d.{vchans,vchanformat,vchanrate} to each of its
     respective node/direction:
       dev.pcm.%d.play.* for "play"   (cdev = dsp%d.vp%d)
       dev.pcm.%d.rec.*  for "record" (cdev = dsp%d.vr%d)
   * Don't expect that it will magically give you ability to split
     "recording source" (eg: 1 channel for cdrom, 1 channel for mic,
     etc). Just admit that you only have a *single* recording source /
     channel. Please bug your hardware vendor instead :)

- Bump maxautovchans from 4 to 16. For a full-fledged multimedia
  desktop/workstation with too many soundservers installed (esound,
  artsd, jackd, pulse/polypaudio, ding-dong pling plong mudkip fuh fuh,
  etc), 4 seems inadequate. There will be no memory penalty here, since
  virtual channels are allocate only by demand.

- Nuke/Rework the entire statically created cdev entries. Everything is
  clonable through snd own clone manager which designed to withstand many
  kind of abusive devfs droids such as:
      * while : ; do /bin/test -e /dev/dsp ; done
      * jot 16777216 0 | while read x ; do ls /dev/dsp0.$x ; done
      * hundreds (could be thousands) concurrent threads/process opening
	"/dev/dsp" (previously, this might result EBUSY even with just
	3 contesting threads/procs).
  o Reusable clone objects (instead of creating new one like there's no
    tomorrow) after certain expiration deadline. The clone allocator will
    decide whether to reuse, share, or creating new clone.
  o Automatic garbage collector.

- Dynamic unit magic allocator. Maximum attached soundcards can be tuned
  using tunable "hw.snd.maxunit" (Default to 512). Minimum is 16, and
  maximum is 2048.

- ..other fixes, mostly related to concurrency issues.

joel@ will do the manpage updates on sound(4).

Have fun.

049c3b6cdf Now that sx(9) locks support an interruptible lock acquire primitive,
properly observe the SB_NOINTR flag in sblock.  This restores the
required behavior that lock acquisition be interruptible on the socket
buffer I/O serialization lock to allow threads waiting for I/O to be
signaled even if they aren't the thread currently holding the I/O lock.
With this change, the sblock regression test is again passed.

f9819486e5 Add functions sx_xlock_sig() and sx_slock_sig().
These functions are intended to do the same actions of sx_xlock() and
sx_slock() but with the difference to perform an interruptible sleep, so
that sleep can be interrupted by external events.
In order to support these new featueres, some code renstruction is needed,
but external API won't be affected at all.

Note: use "void" cast for "int" returning functions in order to avoid tools
like Coverity prevents to whine.

- Coverity Prevent(tm) CID 1906 a bogus use of bzero where unneeded.
 - ICH8 systems autoneg to 100 rather than 1000, this can also be

 - On new 82575 quadports half duplex tx speed is slow... this was due
