Always initialize sc_ekey, because as of r238116 it is always used.

If GELI provider was created on FreeBSD HEAD r238116 or later (but before this
change), it is using very weak keys and the data is not protected.
The bug was introduced on 4th July 2012.

One can verify if its provider was created with weak keys by running:

	# geli dump <provider> | grep version

If the version is 7 and the system didn't include this fix when provider was
initialized, then the data has to be backed up, underlying provider overwritten
with random data, system upgraded and provider recreated.

Begin fleshing out the TX FIFO support.

* Add ATH_TXQ_FIRST() for easy tasting of what's on the list;
* Add an "axq_fifo_depth" for easy tracking of how deep the current
  FIFO is;
* Flesh out the handoff (mcast, hw) functions;
* Begin fleshing out a TX ISR proc, which tastes the TX status FIFO.

The legacy hardware stuffs the TX completion at the end of the final frame
descriptor (or final sub-frame when doing aggregate.)  So it's feasible
to do a per-TXQ drain and process, as the needed info is right there.

For EDMA hardware, there's a separate TX completion FIFO.  So the TX
process routine needs to read the single FIFO and then process the
frames in each hardware queue.

This makes it difficult to do a per-queue process, as you'll end up with
frames in the TX completion FIFO for a different TXQ to the one you've
passed to ath_tx_draintxq() or ath_tx_processq().

Testing:

I've tested the TX queue and TX completion code in hostap mode on an
AR9380.  Beacon frames successfully transmit and the completion routine
is called.  Occasional data frames end up in TXQ 1 and are also
successfully completed.

However, this requires some changes to the beacon code path as:

* The AR9380 beacon configuration API is now in TU/8, rather than
  TU;
* The AR9380 TX API requires the rate control is setup using a call
  to setup11nratescenario, rather than having the try0 series setup
  (rate/tries for the first series); so the beacon won't go out.

I'll follow this up with commits to the beacon code.

I was having TX hang issues, which I root caused to having the

setup code.  This meant that rate control information wasn't being
put into frames, causing the MAC to stall/hang.

Extend the beacon code slightly to support AP mode beaconing for the
EDMA HAL hardware.

* The EDMA HAL code assumes the nexttbtt and intval values are in TU/8
  units, rather than TU.  For now, just "hack" around that here, at least
  until I code up something to translate it in the HAL.
* Setup some different TXQ flags for EDMA hardware.
* The EDMA HAL doesn't support setting the first rate series via
  ath_hal_setuptxdesc() - instead, a call to ath_hal_set11nratescenario()
  is always required.  So for now, just do an 11n rate series setup
  for EDMA beacon frames.

This allows my AR9380 to successfully transmit beacon frames.

However, CABQ TX and all normal data frame TX and TX completion is
still not functional and will require some more significant code churn
to make work.

Break out ath_draintxq() into a method and un-methodize ath_tx_processq().

Now that I understand what's going on with this, I've realised that
it's going to be quite difficult to implement a processq method in
the EDMA case.  Because there's a separate TX status FIFO, I can't
just run processq() on each EDMA TXQ to see what's finished.
i have to actually run the TX status queue and handle individual
TXQs.

So:

* unmethodize ath_tx_processq();
* leave ath_tx_draintxq() as a method, as it only uses the completion status
  for debugging rather than actively completing the frames (ie, all frames
  here are failed);
* Methodize ath_draintxq().

The EDMA ath_draintxq() will have to take care of running the TX
completion FIFO before (potentially) freeing frames in the queue.

The only two places where ath_tx_draintxq() (on a single TXQ) are used:

* ath_draintxq(); and
* the CABQ handling in the beacon setup code - it drains the CABQ before
  populating the CABQ with frames for a new beacon (when doing multi-VAP
  operation.)

So it's quite possible that once I methodize the CABQ and beacon handling,
I can just drop ath_tx_draintxq() in its entirety.

Finally, it's also quite possible that I can remove ath_tx_draintxq()
in the future and just "teach" it to not check the status when doing
EDMA.

Revert the ath_tx_draintxq() method, and instead teach it the minimum
necessary to "do" EDMA.

It was just using the TX completion status for logging information about
the descriptor completion.  Since with EDMA we don't know this without
checking the TX completion FIFO, we can't provide this information.
So don't.

Add support for the so-called streams feature of BULK endpoints
in SUPER-speed mode, USB 3.0.

This feature has not been tested yet, due to lack of hardware.

This feature is useful when implementing protocols like UASP,
USB attached SCSI which promises higher USB mass storage throughput.

This patch also implements support for hardware processing of endpoints
for increased performance. The switching to hardware processing
of an endpoint is done via a callback to the USB controller driver. The
stream feature is implemented like a variant of a hardware USB protocol.

USB controller drivers implementing device mode needs to be updated to
implement the new "xfer_stall" USB controller method and remove the
"xfer" argument from the "set_stall" method.

The API's toward existing USB drivers are preserved. To setup a USB transfer
in stream mode, set the "stream_id" field of the USB config structure to
the desired value.

The maximum number of BULK streams is currently hardcoded and limited to 8
via a define in usb_freebsd.h.

All USB drivers should be re-compiled after this change.

LibUSB will be updated next week to support streams mode. A new IOCTL to
setup BULK streams as already been implemented. The ugen device nodes
currently only supports stream ID zero.

The FreeBSD version has been bumped.

Port the new PV entry allocator from amd64/i386.  This allocator has two
advantages.  First, PV entries are roughly half the size.  Second, this
allocator doesn't access the paging queues, and thus it will allow for the
removal of the page queues lock from this pmap.

Fix a rather serious bug in pmap_remove_write().  After removing write
access from the specified page's first mapping, pmap_remove_write() then
used the wrong "next" pointer.  Consequently, the page's second, third,
etc. mappings were not write protected.

Add locking to the twe(4) driver and make it MPSAFE:
- Add per-controller configuration (sx) and I/O (mutex) locks.  The
  configuration lock protects the relationship of volumes and drives
  while the I/O lock protects access to the controller's registers and
  the main I/O path.
- Remove some checks for M_WAITOK malloc()'s failing.
- Remove the explicit bus space tag/handle from the softc and use
  bus_*() rather than bus_space_*().
- Reuse the existing new-bus sysctl context instead of creating a
  new one.
- Remove compat shims for FreeBSD 4.x.
- Use pci_enable_busmaster() rather than doing it by hand, and rely
  on bus_alloc_resource() to enable PCI I/O decoding.

Do not leave invalid pages in the object after the short read for a
network file systems (not only NFS proper). Short reads cause pages
other then the requested one, which were not filled by read response,
to stay invalid.

Change the vm_page_readahead_finish() interface to not take the error
code, but instead to make a decision to free or to (de)activate the
page only by its validity. As result, not requested invalid pages are
freed even if the read RPC indicated success.

r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions.  In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
 * GCC to default to arm1176jz-s
 * GCC to predefine __FreeBSD_ARCH_armv6__
 * gas to default to ARM_ARCH_V6K
 * uname -p to return 'armv6'
 * make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

Extend the sample mask from 32 bits to 64 bits.

This is required to support > MCS15 as more than 32 bit rate entries are
suddenly available.

This is quite messy - instead of doing typecasts at each mask operation,
this should be migrated to use a macro and have that do the typecast.

Extend the non-aggregate TX descriptor chain routine to be aware of:

* the descriptor ID, and
* the multi-buffer support that the EDMA chips support.

This is required for successful MAC transmission of multi-descriptor
frames.  The MAC simply hangs if there are NULL buffers + 0 length pointers,
but the descriptor did have TxMore set.

This won't be done for the 11n aggregate path, as that will be modified
to use the newer API (ie, ath_hal_filltxdesc() and then set first|middle|
last_aggr), which will deprecate some of the current code.

TODO:

* Populate the numTxMaps field in the HAL, then make sure that's fetched
  by the driver.  Then I can undo that hack.

Tested:

* AR9380, AP mode, TX'ing non-aggregate 802.11n frames;
* AR9280, STA/AP mode, doing aggregate and non-aggregate traffic.

Streamline use of cdevpriv and correct some corner cases.

1) It is not useful to call "devfs_clear_cdevpriv()" from
"d_close" callbacks, hence for example read, write, ioctl and
so on might be sleeping at the time of "d_close" being called
and then then freed private data can still be accessed.
Examples: dtrace, linux_compat, ksyms (all fixed by this patch)

2) In sys/dev/drm* there are some cases in which memory will
be freed twice, if open fails, first by code in the open
routine, secondly by the cdevpriv destructor. Move registration
of the cdevpriv to the end of the drm open routines.

3) devfs_clear_cdevpriv() is not called if the "d_open" callback
registered cdevpriv data and the "d_open" callback function
returned an error. Fix this.

Customer report of a panic on boot due to the old
"m_getjcl:invalid cluster type" that occurred some
time back with the igb driver. This happens often when
booting over the net. I believe the NIC hardware is left
in a warm state when handed over to the driver, and a stray
RX interrupt happens earlier than the code is prepared for
it to happen. This change was verified to fix the problem,
its kind of a bandaid... but it is similar to what was done
in the igb code.

  try to combine physically contiguous pages into regions of these sizes.

- Set the indicate size such that the payload carried in the indicate can
  be copied in the header mbuf (and the 16K rx buffer can be recycled).

- Set DDP threshold to the max payload that the chip will coalesce and
  deliver to the driver (this is ~16K by default, which is also why the
  offload rx queue is backed by 16K buffers).  If the chip is able to
  coalesce up to the max it's allowed to, it's a good sign that the peer
  is transmitting in bulk without any TCP PSH.

Support for TCP DDP (Direct Data Placement) in the T4 TOE module.

Basically, this is automatic rx zero copy when feasible.  TCP payload is
DMA'd directly into the userspace buffer described by the uio submitted
in soreceive by an application.

- Works with sockets that are being handled by the TCP offload engine
  of a T4 chip (you need t4_tom.ko module loaded after cxgbe, and an
  "ifconfig +toe" on the cxgbe interface).
- Does not require any modification to the application.
- Not enabled by default.  Use hw.t4nex.<X>.toe.ddp="1" to enable it.

The TCP PAWS fix for kernels with fast tick rates (r231767) changed the TCP
timestamp related stack variables to reference ms directly instead of ticks.
The h_ertt(4) Khelp module relies on TCP timestamp information in order to
calculate its enhanced RTT estimates, but was not updated as part of r231767.

Consequently, h_ertt has not been calculating correct RTT estimates since
r231767 was comitted, which in turn broke all delay-based congestion control
algorithms because they rely on the h_ertt RTT estimates.

Fix the breakage by switching h_ertt to use tcp_ts_getticks() in place of all
previous uses of the ticks variable. This ensures all timestamp related
variables in h_ertt use the same units as the TCP stack and therefore results in
meaningful comparisons and RTT estimate calculations.

Magic tests containing "search" or "regex" directives were incorrectly

as "troff or preprocessor input, ASCII text".

Fix two problems with pmap_clear_modify().

First, pmap_clear_modify() is write protecting all mappings to the specified
page, not just clearing the modified bit.  Specifically, it sets PTE_RO on
the PTE, which is wrong.  Moreover, it is calling vm_page_dirty(), which is
not the expected behavior for pmap_clear_modify().  Generally speaking, the
machine-independent VM layer masks these mistakes.  For example, setting
PTE_RO will result in additional soft faults, but not a catastrophe.

Second, pmap_clear_modify() may not clear the modified bits because it only
iterates over the PV list when the page has the PV_TABLE_MOD flag set and
elsewhere the pmap clears the PV_TABLE_MOD flag anytime a modified mapping
is write protected or destroyed.  However, the page may still have other
mappings with the modified bit set.

Eliminate a stale comment.

KVM rather than using kmem_alloc_contig().  This avoids requiring

MFC 230547:
Add a timeout on positive name cache entries in the NFS client.  That is,
we will only trust a positive name cache entry for a specified amount of
time before falling back to a LOOKUP RPC, even if the ctime for the file
handle matches the cached copy in the name cache entry.  The timeout is
configured via a global 'vfs.nfs.name_timeout' sysctl and defaults to 60
seconds.  It may be set to zero to disable positive name caching entirely.

Note that this can result in increased NFS traffic under certain workloads.
Increasing the threshold can mitigate this somewhat.  Also, to match the
existing 'vfs.nfs.negative_name_timeout' sysctl in 7, this version uses a
sysctl rather than a mount option as in 8.x and later.
