60b42b1c00 Don't free ressources that haven't been allocated. This should fix
the "disappearing subdisks" problem when new subdisks can't be created
due to some errors.

This is in fact an ugly hack, but a more elegant solution would probably
require a redesign of vinum in several places.

b49d824e8b Add the SF_NODISKIO flag to sendfile. This flag causes sendfile to be
mindful of blocking on disk I/O and instead return EBUSY when such
blocking would occur.

Results from the DeBox project indicate that blocking on disk I/O
can slow the performance of a kqueue/poll based webserver.  Using
a flag such as SF_NODISKIO and throwing connections that would block
to helper processes/threads helped increase performance.

Currently, only the Flash webserver uses this flag, although it could
probably be applied to thttpd with relative ease.

4102d44b77 If a command has to be deferred because there are no more resources for it
on the card, unmap it first.  This allows it to be picked up properly when
the queue gets kicked again.  This was the root problem for the lost command
(i.e. stuck in getblk/vinvalb) problem.  While here, panic if commands don't
map correctly instead of just silently ignoring the problem and dropping
command.  Also slow down the dynamic allocation of new commands.

It should be safe to go back into the aac waters.  Thanks to everyone who
suffered through this and provided good feedback.

9ec5585585 Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772
802.11b chipset work. This chip is present on the SMC2602W version 3
NIC, which is what was used for testing. This driver creates kernel
threads (12 of them!) for various purposes, and required the following
routines:

PsCreateSystemThread()
PsTerminateSystemThread()
KeInitializeEvent()
KeSetEvent()
KeResetEvent()
KeInitializeMutex()
KeReleaseMutex()
KeWaitForSingleObject()
KeWaitForMultipleObjects()
IoGetDeviceProperty()

and several more. Also, this driver abuses the fact that NDIS events
and timers are actually Windows events and timers, and uses NDIS events
with KeWaitForSingleObject(). The NDIS event routines have been rewritten
to interface with the ntoskrnl module. Many routines with incorrect
prototypes have been cleaned up.

Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem())
which block on events, and this interferes with the operation of
NdisMAllocateSharedMemoryAsync(), which was also being put on the
NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync()
is now performed in the NDIS SWI thread instead.

There's still room for some cleanups here, and I really should implement
KeInitializeTimer() and friends.

8f6a5435e7 Reduce AAC_MAX_FIBS to work around some yet-unidentified bugs in the
handling of resources shortages.  The driver is now so fast that it can
completely fill all 512 slots on the card, but for some reason only 511
slots are being allocated.  Anything that tries to go into the 512th
slot gets silently lost.   Both bugs need to be fixed at a later date,
but this should fix the reports of hangs in getblk and vinvalb.

- Try to grab a command before dequeueing the bio from the bioq.  The old

  wrong.  This should be fixed in the future to check the bioq head without
  automatically dequeueing the bio.

91d5354a2c Locking for the per-process resource limits structure.
- struct plimit includes a mutex to protect a reference count.  The plimit
  structure is treated similarly to struct ucred in that is is always copy
  on write, so having a reference to a structure is sufficient to read from
  it without needing a further lock.
- The proc lock protects the p_limit pointer and must be held while reading
  limits from a process to keep the limit structure from changing out from
  under you while reading from it.
- Various global limits that are ints are not protected by a lock since
  int writes are atomic on all the archs we support and thus a lock
  wouldn't buy us anything.
- All accesses to individual resource limits from a process are abstracted
  behind a simple lim_rlimit(), lim_max(), and lim_cur() API that return
  either an rlimit, or the current or max individual limit of the specified
  resource from a process.
- dosetrlimit() was renamed to kern_setrlimit() to match existing style of
  other similar syscall helper functions.
- The alpha OSF/1 compat layer no longer calls getrlimit() and setrlimit()
  (it didn't used the stackgap when it should have) but uses lim_rlimit()
  and kern_setrlimit() instead.
- The svr4 compat no longer uses the stackgap for resource limits calls,
  but uses lim_rlimit() and kern_setrlimit() instead.
- The ibcs2 compat no longer uses the stackgap for resource limits.  It
  also no longer uses the stackgap for accessing sysctl's for the
  ibcs2_sysconf() syscall but uses kernel_sysctl() instead.  As a result,
  ibcs2_sysconf() no longer needs Giant.
- The p_rlimit macro no longer exists.

	Convert the COMPLETE_DMA_SCB list to an "stailq".  This allows us to

	the head of the list while processing completions off of the bus.  The
	newly completed SCBs are appended to the tail of the queue.   In the
	past, we just dequeued the SCB that was in flight from the list, but
	this could result in a lost completion should the host perform certain
	types of error recovery that must cancel all in-flight SCB DMA operations.

	Switch from using a 16bit completion entry, holding just the tag and the
	completion valid bit, to a 64bit completion entry that also contains a
	"status packet valid" indicator.  This solves two problems:
	  o The SCB DMA engine on at least Rev B. silicon does not properly deal
	    with a PCI disconnect that occurs at a non-64bit aligned offset in the
	    chips "source buffer".  When the transfer is resumed, the DMA engine
	    continues at the correct offset, but may wrap to the head of the buffer
	    causing duplicate completions to be reported to the host.  By using a
	    completion buffer in host memory that is 64bit aligned and using 64bit
	    completion entries, such disconnects should only occur at aligned addresses.
	    This assumes that the host bridge will only disconnect on cache-line
	    boundaries and that cache-lines are multpiles of 64bits.

	  o By embedding the status information in the completion entry we can avoid
	    an extra memory reference to the HSCB for commands that complete without
	    error.

	Use the comparison of a "host freeze count" and a "sequencer freeze count"
	to allow the host to process most SCBs that complete with non-zero status
	without having to clear critical sections.  Instead the host can just pause the
	sequencer, performs any necessary cleanup in the waiting for selection list,
	increments its freeze count on the controller, and unpauses.  This is only
	possible because the sequencer defers completions of SCBs with bad status
	until after all pending selections have completed.  The sequencer then avoids
	referencing any data structures the host may touch during completion of the
	SCB until the freeze counts match.

aic79xx.c:
	Change the strategy for allocating our sentinal HSCB for the QINFIFO.  In
	the past, this allocation was tacked onto the QOUTFIFO allocation.  Now that
	the qoutfifo has grown to accomodate larger completion entries, the old
	approach will result in a 64byte allocation that costs an extra page of
	coherent memory.  We now do this extra allocation via ahd_alloc_scbs()
	where the "unused space" can be used to allocate "normal" HSCBs.

	In our packetized busfree handler, use the ENSELO bit to differentiate
	between packetized and non-packetized unexpected busfree events that
	occur just after selection, but before the sequencer has had the oportunity
	to service the selection.

	When cleaning out the waiting for selection list, use the SCSI mode
	instead of the command channel mode.  The SCB pointer in the command
	channel mode may be referenced by the SCB dma engine even while the
	sequencer is paused, whereas the SCSI mode SCB pointer is only accessed
	by the sequencer.

	Print the "complete on qfreeze" sequencer SCB completion list in
	ahd_dump_card_state().  This list holds all SCB completions that are deferred
	until a pending select-out qfreeze event has taken effect.

aic79xx.h:
	Add definitions and structures to handle the new SCB completion scheme.

	Add a controller flag that indicates if the controller is in HostRAID
	mode.

aic79xx.reg:
	Remove macros used for toggling from one data fifo mode to the other.
	They have not been in use for some time.

	Add scratch ram fields for our new qfreeze count scheme, converting
	the complete dma list into an "stailq", and providing for the "complete
	on qfreeze" SCB completion list.  Some other fields were moved to retain
	proper field alignment (alignment >= field size in bytes).

aic79xx.seq:
	Add code to our idle loop to:
	  o Process deferred completions once a qfreeze event has taken full
	    effect.
	  o Thaw the queue once the sequencer and host qfreeze counts match.

	Generate 64bit completion entries passing the SCB_SGPTR field as the
	"good status" indicator.  The first bit in this field is only set if
	we have a valid status packet to send to the host.

	Convert the COMPLETE_DMA_SCB list to an "stailq".

	When using "setjmp" to register an idle loop handler, do not combine
	the "ret" with the block move to pop the stack address in the same
	instruction.  At least on the A, this results in a return to the setjmp
	caller, not to the new address at the top of the stack.  Since we want
	the latter (we want the newly registered handler to only be invoked from
	the idle loop), we must use a separate ret instruction.

	Add a few missing critical sections.

	Close a race condition that can occur on Rev A. silicon.  If both FIFOs
	happen to be allocated before the sequencer has a chance to service the
	FIFO that was allocated first, we must take special care to service the
	FIFO that is not active on the SCSI bus first.  This guarantees that a
	FIFO will be freed to handle any snapshot requests for the FIFO that is
	still on the bus.  Chosing the incorrect FIFO will result in deadlock.

	Update comments.

aic79xx_inline.h
	Correct the offset calculation for the syncing of our qoutfifo.

	Update ahd_check_cmdcmpltqueues() for the larger completion entries.

aic79xx_pci.c:
	Attach to HostRAID controllers by default.  In the future I may add a
	sysctl to modify the behavior, but since FreeBSD does not have any
	HostRAID drivers, failing to attach just results in more email and
	bug reports for the author.

0ee6dbd789 Remove pmap_pvo_allocf zone alloc function. It was a way of
using the direct-mapping of physmem to force PTE data structures
to be physically addressable so the interrupt-time real-mode
DSI trap handler could perform PTE spills. However, the memory
may have been > 256Mb, which would have caused a BAT spill and
double-interrupt.

The new trap code no longer handles PTE spills, so the requirement
that these pages be direct-mapped no longer applies. The irony is
UMA_MD_SMALL_ALLOC will return direct mappings for these structs :-)

 - The temporary register save area has been shifted from
   unused exception vector space to the per-cpu data area.
   This allows interrupts to be delivered to multiple CPUs
 - ISI traps no longer spill to BAT tables. It is assumed
   that all of kernel instruction memory is pinned.
 - shift from 'ldmw/stmw' instructions to individual register

b783c5e972 Correct/improve the implementation of NdisMAllocateSharedMemoryAsync().
Since we have a worker thread now, we can actually do the allocation
asynchronously in that thread's context. Also, we need to return a
status value: if we're unable to queue up the async allocation, we
return NDIS_STATUS_FAILURE, otherwise we return NDIS_STATUS_PENDING
to indicate the allocation has been queued and will occur later.

This replaces the kludge where we just invoked the callback routine
right away in the current context.

36c19a572a Add the kernel side of network interface renaming support.
The basic process is to send a routing socket announcement that the
interface has departed, change if_xname, update the sockaddr_dl
associated with the interface, and announce the arrival of the interface
on the routing socket.

As part of this change, ifunit() is greatly simplified by testing
if_xname directly.  if_clone_destroy() now uses if_dname to look up the
cloner for the interface and if_dunit to identify the unit number.

cea179a3fe Implement support for single packet sends. The Intel Centrino driver
that Asus provides on its CDs has both a MiniportSend() routine
and a MiniportSendPackets() function. The Microsoft NDIS docs say
that if a driver has both, only the MiniportSendPackets() routine
will be used. Although I think I implemented the support correctly,
calling the MiniportSend() routine seems to result in no packets going
out on the air, even though no error status is returned. The
MiniportSendPackets() function does work though, so at least in
this case it doesn't matter.

In if_ndis.c:ndis_getstate_80211(), if ndis_get_assoc() returns
an error, don't bother trying to obtain any other state since the
calls may fail, or worse cause the underlying driver to crash.

(The above two changes make the Asus-supplied Centrino work.)

Also, when calling the OID_802_11_CONFIGURATION OID, remember
to initialize the structure lengths correctly.

In subr_ndis.c:ndis_open_file(), set the current working directory
to rootvnode if we're in a thread that doesn't have a current

ab2bf9ff6a Removed bogus checks that (PCPU_GET(curpcb) != NULL). Rev.1.586 of
machdep.c fixed the missing early initialization of curpcb, so curpcb
is now always set together with curthread and it cannot be NULL except
before the IDT has been set up (so trap() is unreachable) or after a
memory error.  In any case, it was often used without checking.

curcpb shouldn't exist anyway.  It doesn't exist for most non-i386 arches.
It just caches curthread->td_pcb in a global.  This was a better idea
before it was per-cpu.  trap() and some other places can get at it more
efficiently using td->td_pcb instead of PCPU_GET(curpcb).  The main
exception is support.s which mostly wants only curpcb->pcb_onfault.

322141f1e2 If the temperature is at _HOT or _CRT for 3 sequential readings, shutdown
the system.  Also, decrease the poll interval to 10 seconds from 30
seconds.  This is needed because some systems will report an invalid high
temperature for one poll cycle.  It is suspected this is due to the
embedded controller timing out.  A typical value is 138C for one cycle on a
system that is otherwise 65C.  This prevents the system from prematurely
shutting down after one invalid reading.  It will still shut down after 30
seconds of high temperature, which is the same as previous default

f0aed0dbd0 Use the OID_802_11_CONFIGURATION OID when deciding if the underlying driver
is for an 802.11 device or not. At least one driver I have does not
support the OID_802_11_NETWORK_TYPES_SUPPORTED OID.

Also, for now, don't do anything special in the ndis_suspend() method.
I originally wanted to shut down the NIC but leave the IFF_UP flag alone
since technically the interface is meant to remain up, but an interrupt
may be delivered to the ISR on suspend, and if this happens while the
NIC is halted, we will crash, since none of the miniport driver methods
will function.

8600a4122a Eliminate all TLB shootdowns by pmap_pte_quick(): By temporarily pinning
the thread that calls pmap_pte_quick() and by virtue of the page queues
lock being held, we can manage PADDR1/PMAP1 as a CPU private mapping.

The most common effect of this change is to reduce the overhead of the page
daemon on multiprocessors.

beb699c7ba Rewrite sendfile's header support so that headers are now sent in the first
packet along with data, instead of in their own packet.  When serving files
of size (packetsize - headersize) or smaller, this will result in one less
packet crossing the network.  Quick testing with thttpd and http_load has
shown a noticeable performance improvement in this case (350 vs 330 fetches
per second.)

Included in this commit are two support routines, iov_to_uio, and m_uiotombuf;
these routines are used by sendfile to construct the header mbuf chain that
will be linked to the rest of the data in the socket buffer.

4795b82c13 Coalesce pipe allocations and frees. Previously, the pipe code
would allocate two 'struct pipe's from the pipe zone, and malloc a
mutex.

- Create a new "struct pipepair" object holding the two 'struct
  pipe' instances, struct mutex, and struct label reference.  Pipe
  structures now have a back-pointer to the pipe pair, and a
  'pipe_present' flag to indicate whether the half has been
  closed.

- Perform mutex init/destroy in zone init/destroy, avoiding
  reallocating the mutex for each pipe.  Perform most pipe structure
  setup in zone constructor.

- VM memory mappings for pageable buffers are still done outside of
  the UMA zone.

- Change MAC API to speak 'struct pipepair' instead of 'struct pipe',
  update many policies.  MAC labels are also handled outside of the
  UMA zone for now.  Label-only policy modules don't have to be
  recompiled, but if a module is recompiled, its pipe entry points
  will need to be updated.  If a module actually reached into the
  pipe structures (unlikely), that would also need to be modified.

These changes substantially simplify failure handling in the pipe
code as there are many fewer possible failure modes.

On half-close, pipes no longer free the 'struct pipe' for the closed
half until a full-close takes place.  However, VM mapped buffers
are still released on half-close.

Some code refactoring is now possible to clean up some of the back
references, etc; this patch attempts not to change the structure
of most of the pipe implementation, only allocation/free code
paths, so as to avoid introducing bugs (hopefully).

This cuts about 8%-9% off the cost of sequential pipe allocation
and free in system call tests on UP and SMP in my micro-benchmarks.
May or may not make a difference in macro-benchmarks, but doing
less work is good.

9a44a82b61 Fixed breakage of scheduling in rev.1.29 of subr_4bsd.c. The
"scheduler" here has very little to do with scheduling.  It is actually
the swapper, and it really must be the last SYSINIT'ed item like its
comment says, since proc0 metamorphoses into swapper by calling
scheduler() last in mi_start(), and scheduler() never returns..  Rev.1.29
of subr_4bsd.c broke this by adding another SI_ORDER_FIRST item
(kproc_start() for schedcpu_thread() onto the SI_SUB_RUN_SCHEDULER_LIST.
The sorting of SYSINITs with identical orders (at all levels) is
apparently nondeterministic, so this resulted in schedule() sometimes
being called second last and schedcpu_thread() not being called at all.

This quick fix just changes the code to almost match the comment
(SI_ORDER_FIRST -> SI_ORDER_ANY).  "LAST" is misspelled "ANY", and
there is no way to ensure that there is only 1 very lst SYSINIT.
A more complete fix would remove the SYSINIT obfuscation.

8d768e7676 Rework witness_lock() to make it slightly more useful and flexible.
- witness_lock() is split into two pieces: witness_checkorder() and
  witness_lock().  Witness_checkorder() determines if acquiring a specified
  lock at the time it is called would result in a lock order.  It
  optionally adds a new lock order relationship as well.  witness_lock()
  updates witness's data structures to assume that a lock has been acquired
  by stick a new lock instance in the appropriate lock instance list.
- The mutex and sx lock functions now call checkorder() prior to trying to
  acquire a lock and continue to call witness_lock() after the acquire is
  completed.  This will let witness catch a deadlock before it happens
  rather than trying to do so after the threads have deadlocked (i.e. never
  actually report it).
- A new function witness_defineorder() has been added that adds a lock
  order between two locks at runtime without having to acquire the locks.
  If the lock order cannot be added it will return an error.  This function
  is available to programmers via the WITNESS_DEFINEORDER() macro which
  accepts either two mutexes or two sx locks as its arguments.
- A few simple wrapper macros were added to allow developers to call
  witness_checkorder() anywhere as a way of enforcing locking assertions
  in code that might acquire a certain lock in some situations.  The
  macros are: witness_check_{mutex,shared_sx,exclusive_sx} and take an
  appropriate lock as the sole argument.
- The code to remove a lock instance from a lock list in witness_unlock()
  was unnested by using a goto to vastly improve the readability of this
  function.

12e524a290 Change KASSERT() in feed_vchan16() into an explicit test and call to
panic() so that the buffer overflow just beyond this point is always
caught, even when the code is not compiled with INVARIANTS.

Change chn_setblocksize() buffer reallocation code to attempt to avoid
the feed_vchan16() buffer overflow by attempting to always keep the
bufsoft buffer at least as large as the bufhard buffer.

Print a diagnositic message
	Danger! %s bufsoft size increasing from %d to %d after CHANNEL_SETBLOCKSIZE()
if our best attempts fail.  If feed_vchan16() were to be called by
the interrupt handler while locks are dropped in chn_setblocksize()
to increase the size bufsoft to match the size of bufhard, the panic()
code in feed_vchan16() will be triggered.  If the diagnostic message
is printed, it is a warning that a panic is possible if the system
were to see events in an "unlucky" order.

Change the locking code to avoid the need for MTX_RECURSIVE mutexes.

Add the MTX_DUPOK option to the channel mutexes and change the locking
sequence to always lock the parent channel before its children to avoid
the possibility of deadlock.

Actually implement locking assertions for the channel mutexes and fix
the problems found by the resulting assertion violations.

Clean up the locking code in dsp_ioctl().

Allocate the channel buffers using the malloc() M_WAITOK option instead
of M_NOWAIT so that buffer allocation won't fail.  Drop locks across
the malloc() calls.

Add/modify KASSERTS() in attempt to detect problems early.

Abuse layering by adding a pointer to the snd_dbuf structure that points
back to the pcm_channel that owns it.  This allows sndbuf_resize() to do
proper locking without having to change the its API, which is used by
the hardware drivers.

4158244cc0 Allow the use of a stale p_stops value in STOPEVENT(), grabbing
the proc lock only if we actually need to perform a stop.  This
avoids two locks and unlocks of the process lock each system call,
and wins me about 20% on a simply system call test (getuid(),
which would otherwise require no locking).  This also has a net
improvement of about 10MB/s on some of the SMP bandwidth tests
I'm running.

a8773564ca Cleanup malloc() use in if_attach():
- malloc() returns a void* and does not need a cast
 - when called with M_WAITOK, malloc() can not return NULL so don't
   check for that case.  The result of the check was bogus anyway since
   it would leave the interface broken.

84344f9fbf Rename the kern.vm.kmem.size tunable to the more logical vm.kmem_size. To
assure backward compatibility (conditional on !BURN_BRIDGES), look it up
by its old name first, and log a warning (but accept the setting) if it
was found.  If both the old and new name are defined, the new name takes
precedence.

Also export vm.kmem_size as a read-only sysctl variable; I find it hard to
tune a parameter when I don't know its default value, especially when that
default value is computed at boot time.

823261a3e1 While USB keyboards attach as ukbd[0-9]+, the device node created by
kbd_attach() is called kbd[0-9]+, with a different unit number.  This
makes it impossible to write a devd rule which will automatically
switch to a USB keyboard when one is attached, because there is no way
to guess the correct device node to pass to kbdcontrol.

Therefore, change kbd_attach() to create a device node using the
keyboard device's real name (atkbd0, ukbd0...), and create the
kbd[0-9]+ node as an alias for backward compatibility.

581b0a24bc Reorganize the timer code a little and implement NdisInitializeTimer()
and NdisCancelTimer(). NdisInitializeTimer() doesn't accept an NDIS
miniport context argument, so we have to derive it from the timer
function context (which is supposed to be the adapter private context).
NdisCancelTimer is now an alias for NdisMCancelTimer().

Also add stubs for NdisMRegisterDevice() and NdisMDeregisterDevice().
These are no-ops for now, but will likely get fleshed in once I start
working on the Am1771/Am1772 wireless driver.

afa632035c - Call acpi_Startup() before parsing interrupt-related APIC resources so we
can look at the ACPI tables.  If the startup fails, we panic and tell the
  user to try rebooting with ACPI disabled.  Previously in this case we
  would try to use $PIR interrupt routing which only works for the atpic
  while using the apic to handle interrupts which would result in misrouted
  interrupts and a hang at boot time with no error message.
- Read the SCI out of the FADT instead of hardcoding 9 when checking to see
  if an interrupt override entry is for the SCI.
- Try to work around some BIOS brain damage for the SCI's programming by
  forcing the SCI to be level triggered and active low if it is routed
  to a non-ISA interrupt (greater than 15) or if it is identity mapped with
  edge trigger and active high polarity.  This should fix some of the hangs
  with device apic and ACPI that some people see.

problem here still to be solved: the sockaddr_hci has still a 16 byte
field for the node name. The code currently does not correctly use the
length field in the sockaddr to handle the address length, so
node names get truncated to 15 characters when put into a sockaddr_hci.
