1108975fe0 Initialize eflags in fake frame to default value rather than random one.
The random value sometimes causes macro CLKF_USERMODE to return true
because PSL_VM bit is set and really shoudn't be, this causes statclock()
to execute in wrong path, and further breaks KSE code and kernel crashes
when executing threaded program.

ea6ff0649f Limit our requests to DFLTPHYS, this is generally a good idea for

because we hit a Giant assertion in the free(9) processing if we

2cd3cc377a aic79xx.c:
Include read streaming in the PPR flags we display in diagnostics.

	In ahd_reset(), set the known mode after our initial pause prior to
	setting the mode. We can't just set the mode directly because the
	current mode, after the pause, is most likely unknown and setting the
	mode when the saved mode is unknown will trigger an assertion in
	the mode debug code.

	Complete an audit for SCB RAM reads.  These reads must be performed
	via the special ahd_in?_scbram() methods so we can perform a
	Rev A. PCI-X workaround.

	Remove a superfluous mode save operation that was performed just
	prior to a call to ahd_clear_critical_section().  The saved mode
	was never restored and wouldn't have been valid anyway since the
	mode could change while single stepping out of a critical section.

aic79xx.h:
	Add new BUG definition AHD_PCIX_SCBRAM_RD_BUG.

aic79xx_inline.h:
	Update ahd_inb_scbram routine to check for AHD_PCIX_SCBRAM_RD_BUG
	and only apply the workaround if this bug is active.  The old code
	applied the workaround in all cases.

aic79xx_pci.c:
	Set AHD_PCIX_SCBRAM_RD_BUG for the A4.

	Remove an attempted saved_modes call in ahd_pci_test_register_access().
	Saving the modes can only occur when we are paused, but the call was
	happening before the chip was known to be paused.  Restoring the
	modes doesn't make sense either since the code makes no assumptions
	about the state of the sequencer until the first time the mode is set
	by the driver.  This happens after the registers are successfully
	mapped.

9da590b49b Oops, fix the double faults people were seeing with the recent changes to
witness.  Sleepable locks such as sx locks always come before all mutexes
including Giant.  However, the static lock order list placed Giant before
the proctree and allproc sx locks.  This resulted in witness creating a
cycle in its lock order "tree" (real trees don't have cycles) leading to
infinite recursion and eventually a double fault.  To fix, put Giant after
sx locks in the lock order list.

they were primarily interested in the fact that it was a meta-data
write, not the contents of the write), but would be relevant to
future modules relying on that field.

ee844411e9 Raise the default value of TTYHOG from 1 kB to 8 kB. Since TTYHOG is
an administrative limit on the size of tty/pty input buffers, this is
mostly an inconsequential change.  (slti(4) will allocate an 8 kB
static buffer instead of a 1 kB buffer due to a hack in the driver.)
The increase happens to kludge around a lame limitation of syscons,
which does not allow one to paste more than TTYHOG bytes.

cafd6dbd76 Fix threaded applications on ia64 that are linked dynamicly. We did
not save (restore) the global pointer (GP) in the jmpbuf in setjmp
(longjmp) because it's not needed in general. GP is considered a
scratch register at callsites and hence is always restored after a
call (when it's possible that the call resolves to a symbol in a
different loadmodule; otherwise GP does not have to be saved and
restored at all), including calls to setjmp/longjmp. There's just
one problem with this now that we use setjmp/longjmp for context
switching: A new context must have GP defined properly for the
thread's entry point. This means that we need to put GP in the
jmpbuf and consequently that we have to restore is in longjmp.
This automaticly requires us to save it as well.

When setjmp/longjmp isn't used for context switching, this can be
reverted again.

a402169a8e ABI breaker: Move the J_SIGMASK field in the jmpbuf before
the J_SIG0 field. While here, rename J_SIG0 to J_SIGSET and
remove J_SIG1. The main reason for this change is that the
128-bit sigset_t is now aligned on a 16-byte boundary, which
allows us to use 16-byte atomic loads and stores on CPUs that
support it. The removal of J_SIG1 is done to avoid confusion:
it is never accessed and should not be. Renaming J_SIG0 to
J_SIGSET is the icing on the cake that's better done now than
later.

24deed1aaa - Hold the buf lock while manipulating and inspecting its fields.
- Use gbincore() and not incore() so that we can drop the vnode interlock
   as we acquire the buflock.
 - Use GB_LOCK_NOWAIT when getting bufs for read ahead clusters so that we
   don't block on locked bufs.
 - Convert a while loop to a howmany() that will most likely be faster on
   modern processors.  There is another while loop divide that was left
   near by because it is operating on a 64bit int and is most likely faster.
 - Cleanup the cluster_read() code a little to get rid of a goto and make
   the logic clearer.

35580ede37 A small overhaul of witness:
- Add a comment about special lock order rules and Giant near the top of
  subr_witness.c.  Specifically, this documents and explains the real lock
  order relationship between Giant and sleepable locks (i.e. lockmgr locks
  and sx locks).  Basically, Giant can be safely acquired either before or
  after sleepable locks and the case of Giant before a sleepable lock is
  exempted as a special case.
- Add a new static function 'witness_list_lock()' that displays a single
  line of information about a struct lock_instance.  This is used to
  make the output of witness messages more consistent and reduce some code
  duplication.
- Fixup a few comments in witness_lock().
- Properly handle the Giant-before-sleepable-lock lock order exception in
  a more general fashion and remove the no longer needed LI_SLEPT flag.
- Break up the last condition before assuming a reversal a bit to try
  and make the logic less confusing in witness_lock().
- Axe WITNESS_SLEEP() now that LI_SLEPT is no longer needed and replace it
  with a more general WITNESS_WARN() macro/function combination.
  WITNESS_WARN() allows you to output a customized message out to the
  console along with a list of held locks.  It will optionally drop into
  the debugger as well.  You can exempt a single lock from the check by
  passing it in as the second argument.  You can also use flags to specify
  if Giant should be exempt from the check, if all sleepable locks should
  be exempt from the check, and if witness should panic if any non-exempt
  locks are found.
- Make the witness_list() function static.  Other areas of the kernel
  should use the new WITNESS_WARN() instead.

65c8760dbf - Shift the tick count by 10 and back around sched_pctcpu_update()
calculations.  Keep this changes local to the function so the tick count
   is in its natural form otherwise.  Previously 1000 was added each time
   a tick fired and we divided by 1000 when it was reported.  This is done
   to reduce rounding errors.

dcae7539cb Defer allowing async. requests after self ID's have received.
This should fix some problem of SBP2 device probing.

Prior to rev 1.41, we keep writing the register while bus reset phase.
But in rev 1.41, we ignore successive bus reset events and some chips seem to
clear the register after we write to it.

03d031626d A cute yet small MAC policy that provides a simple ACL mechanism to
permit users and groups to bind ports for TCP or UDP, and is intended
to be combined with the recently committed support for
net.inet.ip.portrange.reservedhigh.  The policy is twiddled using
sysctl(8).  To use this module, you will need to compile in MAC
support, and probably set reservedhigh to 0, then twiddle
security.mac.portacl.rules to set things as desired.  This policy
module only restricts ports explicitly bound using bind(), not
implicitly bound ports where the port number is selected by the
IP stack.  It appears to work properly in my local configuration,
but needs more broad testing.

A sample policy might be:

  # sysctl security.mac.portacl.rules="uid:425:tcp:80,uid:425:tcp:79"

This permits uid 425 to bind TCP sockets to ports 79 and 80.  Currently
no distinction is made for incoming vs. outgoing ports with TCP,
although that would probably be easy to add.

5dfe609dd1 Add two loader tuneables that allow one to change the maximum number of
queue items that can be allocated by netgraph and the number of free queue
items that are cached on a private list.

Netgraph places an upper limit on the number of queue items it may allocate.
When there is a large number of netgraph messages travelling through the
system (100k/sec and more) there is a high probability, that messages get
queued at the nodes and netgraph runs out of queue items. In this case the data
flow through netgraph gets blocked. The tuneable for the number of free
items lets one trade memory for performance.

The tunables are also available as read-only sysctls.

acae33b029 aic79xx.c:
Clear the LQICRC_NLQ status should it pop up after we have
	already handled the SCSIPERR.  During some streaming operations
	this status can be delayed until the stream ends.  Without this
	change, the driver would complain about a "Missing case in
	ahd_handle_scsiint".

	In the LQOBUSFREE handler...

		Don't return the LQOMGR back to the idle state until after
		we have cleaned up ENSELO and any status related to this
		selection.  The last thing we need is the LQO manager starting
		another select-out before we have updated the execution queue.
		It is not clear whether the LQOMGR would, or would not
		start a new selection early.

		Make sure ENSELO is off prior to clearing SELDO by flushing
		device writes.

		Move assignment of the next target SCB pointer inside of
		an if to make the code clearer.  The effect is the same.

	Dump card state in both "Unexpected PKT busfree" paths.

	In ahd_reset(), set the chip to SCSI mode before reading SXFRCTL1.
	That register only exists in the SCSI mode.  Also set the mode
	explicitly to the SCSI mode after chip reset due to paranoia.
	Re-arrange code so that SXFRCTL1 is restored as quickly after the
	chip reset as possible.

	S/G structurs must be 8byte aligned.  Make this official by saying
	so in our DMA tag.

	Disable CIO bus stretch on MDFFSTAT if SHVALID is about to come
	true.  This can cause a CIO bus lockup if a PCI or PCI-X error
	occurs while the stretch is occurring - the host cannot service
	the PCI-X error since the CIO bus is locked out and SHVALID will
	never resolve.  The stretch was added in the Rev B to simplify the
	wait for SHVALID to resolve, but the code to do this in the open
	source sequencer is so simple it was never removed.

	Consistently use MAX_OFFSET for the user max syncrate set from
	non-volatile storage.  This ensures that the offset does not
	conflict with AH?_OFFSET_UNKNOWN.

	Have ahd_pause_and_flushwork set the mode to ensure that it has
	access to the registers it checks.  Also modify the checking of
	intstat so that the check against 0xFF can actually succeed if
	the INT_PEND mask is something other than 0xFF.  Although there
	are no cardbus U320 controllers, this check may be needed to
	recover from a hot-plug PCI removal that occurs without informing
	the driver.

	Fix a typo.  sg_prefetch_cnt -> sg_prefetch_align.  This fixes
	an infinite loop at card initialization if the cacheline size is 0.

aic79xx.h:
	Add AHD_EARLY_REQ_BUG bug flag.

	Fix spelling errors.

	Include the CDB's length just after the CDB pointer in the DMA'ed
	CDB case.

	Change AH?_OFFSET_UNKNOWN to 0xFF.  This is a value that the
	curr->offset can never be, unlike '0' which we previously used.
	This fixes code that only checks for a non-zero offset to
	determine if a sync negotiation is required since it will fire
	in the unknown case even if the goal is async.

aic79xx.reg:
	Add comments for LQISTAT bits indicating their names in the 7902
	data book.  We use slightly different and more descriptive names
	in the firmware.

	Fix spelling errors.

	Include the CDB's length just after the CDB pointer in the DMA'ed
	CDB case.

aic79xx.seq:
	Update comments regarding rundown of the GSFIFO to reflect reality.

	Fix spelling errors.

	Since we use an 8byte address and 1 byte length, shorten the size
	of a block move for the legacy DMA'ed CDB case from 11 to 9 bytes.

	Remove code that, assuming the abort pending feature worked, would
	set MK_MESSAGE in the SCB's control byte on completion to catch
	invalid reselections.  Since we don't see interrupts for completed
	selections, this status update could occur prior to us noticing the
	SELDO.  The "select-out" queue logic will get confused by the
	MK_MESSAGE bit being set as this is used to catch packatized
	connections where we select-out with ATN.  Since the abort pending
	feature doesn't work on any released controllers yet, this code was
	never executed.

	Add support for the AHD_EARLY_REQ_BUG.  Don't ignore persistent REQ
	assertions just because they were asserted within the bus settle delay
	window.  This allows us to tolerate devices like the GEM318 that
	violate the SCSI spec.

	Remove unintentional settnig of SG_CACHE_AVAIL.  Writing this bit
	should have no effect, but who knows...

	On the Rev A, we must wait for HDMAENACK before loading additional
	segments to avoid clobbering the address of the first segment in
	the S/G FIFO.  This resolves data-corruption issues with certain
	IBM (now Hitachi) and Fujitsu U320 drives.

	Rearrange calc_residual to avoid an extra jmp instruction.

	On RevA Silicon, if the target returns us to data-out after we
	have already trained for data-out, it is possible for us to
	transition the free running clock to data-valid before the required
	100ns P1 setup time (8 P1 assertions in fast-160 mode).  This will
	only happen if this L-Q is a continuation of a data transfer for
	which we have already prefetched data into our FIFO (LQ/Data
	followed by LQ/Data for the same write transaction).  This can
	cause some target implementations to miss the first few data
	transfers on the bus.  We detect this situation by noticing that
	this is the first data transfer after an LQ (LQIWORKONLQ true),
	that the data transfer is a continuation of a transfer already
	setup in our FIFO (SAVEPTRS interrupt), and that the transaction
	is a write (DIRECTION set in DFCNTRL). The delay is performed by
	disabling SCSIEN until we see the first REQ from the target.

	Only compile in snapshot savepointers handler for RevA silicon
	where it is enabled.

	Handle the cfg4icmd packetized interrupt.  We just need to load
	the address and count, start the DMA, and CLRCHN once the transfer
	is complete.

	Fix an oversight in the overrun handler for packetized status
	operations.  We need to wait for either CTXTDONE or an overrun
	when checking for an overrun.  The previous code did not wait
	and thus could decide that no overrun had occurred even though
	an overrun will occur on the next data-valid req.  Add some
	comment to this section for clarity.

	Use LAST_SEG_DONE instead of LASTSDONE for testing transfer
	completion in the packetized status case.  LASTSDONE may come up
	more quickly since it only records completion on the SCSI side,
	but since LAST_SEG_DONE is used everywhere else (and needs to be),
	this is less confusing.

	Add a missing invalidation of the longjmp address in the non-pack
	handler.  This code needs additional review.

aic79xx_inline.h:
	Fix spelling error.

aic79xx_osm.c:
	Set the cdb length for CDBs dma'ed from host memory.

	Add a comment indicating that, should CAM start supporting cdbs
	larger than 16bytes, the driver could store the CDB in the status
	buffer.

aic79xx_pci.c:
	Add a table entry for the 39320A.

	Added a missing comma to an error string table.

	Fix spelling errors.
