18835ea4fb During work to port isci(4) to stable/7 I noted that the maxio portion of
struct ccb_pathinq from sys/cam/cam_ccb.h wasn't added to stable/7 at all
and didn't appear in stable/8 until svn R195534.  Since __FreeBSD_version
did not get bumped until svn R195634, assume that maxio is valid at 800102
or higher.

0f8150f67b Enforce some consistent ordering and handling of interrupt disable/enable
with RX/TX halting.

* Always disable/enable interrupts during a channel change, just to simply
  things.

* Ensure that the ath taskqueue has completed and is paused before
  continuing.

This dramatically reduces the instances of overlapping RX and reset
conditions.

dcdb23291f Merge multi-FIB IPv6 support from projects/multi-fibv6/head/:
Extend the so far IPv4-only support for multiple routing tables (FIBs)
introduced in r178888 to IPv6 providing feature parity.

This includes an extended rtalloc(9) KPI for IPv6, the necessary
adjustments to the network stack, and user land support as in netstat.

a50c43eae7 Fix a bug in the calculation of the maximum I/O request size.
The previous code did not limit the I/O request size based on
the maximum number of segments supported by the back-end.  In
current practice, since the only back-end supporting chained
requests is the FreeBSD implementation, this limit was never
exceeded.

sys/dev/xen/blkfront/block.h:
	Add two macros, XBF_SEGS_TO_SIZE() and XBF_SIZE_TO_SEGS(),
	to centralize the logic of reserving a segment to deal with
	non-page-aligned I/Os.

sys/dev/xen/blkfront/blkfront.c:
	o When negotiating transfer parameters, limit the
	  max_request_size we use and publish, if it is greater
	  than the maximum, unaligned, I/O we can support with
	  the number of segments advertised by the backend.
	o Don't unilaterally reduce the I/O size published to
	  the disk layer by a single page.  max_request_size
	  is already properly limited in the transfer parameter
	  negotiation code.
	o Fix typos in printf strings:
		"max_requests_segments" -> "max_request_segments"
		"specificed" -> "specified"

da3ed1879e Refactor the name hash and the ID hash, that are used to address nodes:
- Make hash sizes growable, to satisfy users running large mpd
  installations, having thousands of nodes.
- NG_NAMEHASH() proved to give a very bad distribution in real life
  name sets, while generic hash32_str(name, HASHINIT) proved to give
  an even one, so you the latter for name hash.
- Do not store unnamed nodes in slot 0 of name hash, no reason for that.
- Use the ID hash in cases when we need to run through all nodes: the
  NGM_LISTNODES command and in the vnet_netgraph_uninit().
- Implement NGM_LISTNODES and NGM_LISTNAMES as separate code, the former
  iterates through the ID hash, and the latter through the name hash.
- Keep count of all nodes and of named nodes, so that we don't need
  to count nodes in NGM_LISTNODES and NGM_LISTNAMES. The counters are
  also used to estimate whether we need to grow hashes.
- Close a race between two threads running ng_name_node() assigning same
  name to different nodes.

1ms < x < 1s per tick as mandated by RFC1323, leading to connection

Always use a granularity of 1ms using getmicrouptime() making all but
relevant callouts independent of hz.

Use getmicrouptime(), not getmicrotime() as the latter may make a jump
possibly breaking TCP nfsroot mounts having our timestamps move forward

	o Defer connection shutdown processing until the front-end
	  enters the closed state.  This avoids prematurely tearing
	  down the connection when buggy front-ends transition to the

	  veto the close request from the tool stack.
	o Add nodes for maximum request size and the number of active

	o Miscelaneous style cleanup.

set all three of the kernel, supervisor, and user-mode 64-bit mode
flags.  While FreeBSD does not currently use the supervisor ring (and
hence this is effectively a NOP on most systems), doing this avoids
triggering an exception on 64-bit MIPS CPUs that don't support 32-bit
compatibility mode, and therefore don't allow clearing the SX bit.

  Also not that this quirk entry currently doesn't affect the devices

panic due to a destroyed semaphore.

Instead, ensure that the callout is done first, via callout_drain.

Note that this fix applies to the "old" ata(4) and so isn't applicable
to the default configuration in HEAD.  It is still applicable to

635374749a Attempt to address some potential vap->iv_bss race conditions.
There are unfortunately a number of situations where vap->iv_bss is changed
or freed by some code in net80211.  Because multiple threads can concurrently
be doing work (and the vap->iv_bss access isn't at all done behind any kind
of lock), it's quite possible that:

* a change will occur in one thread - eg, by a call through
  ieee80211_sta_join1();
* a state change occurs in another thread - eg an RX is scheduled
  in the ath tasklet and it calls ieee80211_input_mimo_all(), which
  does dereference vap->iv_bss;
* these two executing concurrently, causing things to explode.

Another instance is ath_beacon_alloc() which takes an ieee80211_node *.
It's called with the vap->iv_bss node from ath_newstate(). If the node has
changed in the meantime (say it's been freed elsewhere) the reference
that it grabbed _before_ refcounting it may be stale.

I would _prefer_ that these sorts of things were serialised somewhere but
that may be a bit much to ask.  Instead, the best we can (currently) hope
is that the underlying bss node is still (somewhat) valid.

There is a related PR (kern/164382) described by the first case above.
That should be fixed by properly serialising the RX path and reset path
so an RX can't occur at the same time as the vap free/shutdown path.

This is inspired by some related fixes in r212127.

- The I/O port resource may not be available with these. However, given
  that we actually only need this resource for some controllers that
  require their firmware to be up- and downloaded (which excludes the

ae00704002 Historically when an application wrote an entire block of a file,
the kernel allocated a buffer but did not zero it as it was about
to be completely filled by a uiomove() from the user's buffer.
However, if the uiomove() failed, the old contents of the buffer
could be exposed especially if the file was being mmap'ed. The
fix was to always zero the buffer when it was allocated.

This change first attempts the uiomove() to the newly allocated
(and dirty) buffer and only zeros it if the uiomove() fails. The
effect is to eliminate the gratuitous zeroing of the buffer in
the usual case where the uiomove() successfully fills it.

56527fa077 Bring in a number of mps(4) driver fixes from LSI:
1.  Fixed timeout specification for the msleep in mps_wait_command().
    Added 30 second timeout for mps_wait_command() calls in mps_user.c.

2.  Make sure we call mps_detach_user() from the kldunload path.

3.  Raid Hotplug behavior change.

    The driver now removes a volume when it goes to a failed state,
    so we also need to add volume back to the OS when it goes to
    opitimal/degraded/online from failed/missing.

    Handle raid volume add and remove from the IR_Volume event.
4.  Added some more debugging information.

5.  Replace xpt_async(AC_LOST_DEVICE, path, NULL) with
    mpssas_rescan_target().

    This is to work around a panic in CAM that shows up when adding a
    drive with a rescan and removing another device from the driver thread
    with an AC_LOST_DEVICE async notification.

    This problem was encountered in testing with the LSI sas2ircu utility,
    which was used to create a RAID volume from physical disks.  The driver
    has to create the RAID volume target and remove the physical disk
    targets, and triggered a panic in the process.

    The CAM issue needs to be fully diagnosed and fixed, but this works
    around the issue for now.

6.  Fix some memory initialization issues in mps_free_command().

7.  Resolve the "devq freeze forever" issue.  This was caused by the
    internal read capacity command issued in the non-head version of the
    driver.  When the command completed with an error, the driver wasn't
    unfreezing thd device queue.

    The version in head uses the CAM infrastructure for getting the read
    capacity information, and therefore doesn't have the same issue.

8.  Bump the version to 13.00.00.00-fbsd. (this is very close to LSI's
    internal stable driver 13.00.00.00)

3619d603a7 In the original days of BSD, a sync was issued on every filesystem
every 30 seconds. This spike in I/O caused the system to pause every
30 seconds which was quite annoying. So, the way that sync worked
was changed so that when a vnode was first dirtied, it was put on
a 30-second cleaning queue (see the syncer_workitem_pending queues
in kern/vfs_subr.c). If the file has not been written or deleted
after 30 seconds, the syncer pushes it out. As the syncer runs once
per second, dirty files are trickled out slowly over the 30-second
period instead of all at once by a call to sync(2).

The one drawback to this is that it does not cover the filesystem
metadata. To handle the metadata, vfs_allocate_syncvnode() is called
to create a "filesystem syncer vnode" at mount time which cycles
around the cleaning queue being sync'ed every 30 seconds. In the
original design, the only things it would sync for UFS were the
filesystem metadata: inode blocks, cylinder group bitmaps, and the
superblock (e.g., by VOP_FSYNC'ing devvp, the device vnode from
which the filesystem is mounted).

Somewhere in its path to integration with FreeBSD the flushing of
the filesystem syncer vnode got changed to sync every vnode associated
with the filesystem. The result of this change is to return to the
old filesystem-wide flush every 30-seconds behavior and makes the
whole 30-second delay per vnode useless.

This change goes back to the originally intended trickle out sync
behavior. Key to ensuring that all the intended semantics are
preserved (e.g., that all inode updates get flushed within a bounded
period of time) is that all inode modifications get pushed to their
corresponding inode blocks so that the metadata flush by the
filesystem syncer vnode gets them to the disk in a timely way.
Thanks to Konstantin Belousov (kib@) for doing the audit and commit
-r231122 which ensures that all of these updates are being made.

c9e28aac3f r228827 fixed a problem where copying of NFSv4 open credentials into
a credential structure would corrupt it. This happened when the
p argument was != NULL. However, I now realize that the copying of
open credentials should only happen for p == NULL, since that indicates
that it is a read-ahead or write-behind. This patch fixes this.
After this commit, r228827 could be reverted, but I think the code is
clearer and safer with the patch, so I am going to leave it in.
Without this patch, it was possible that a NFSv4 VOP_SETATTR() could have
changed the credentials of the caller. This would have happened if
the process doing the VOP_SETATTR() did not have the file open, but
some other process running as a different uid had the file open for writing
at the same time.

021c66f70f Contribute some example code which demonstrates how to initialise the
radar parameters for the AR5416 and later NICs.

These parameters have been tested on the following NICs:

* AR5416
* AR9160
* AR9220
* AR9280

And yes, these will return radar pulse parameters and (for AR9160 and later)
radar FFT information as PHY errors.

This is again not enough to do radar detection, it's just here to faciliate
development and validation of radar detection algorithms.

The (pulse, not FFT) decoding code for AR5212, AR5416 and later NICs exist
in the HAL.

This code is disabled for now as generating radar PHY errors can quickly
cause issues in busy environment.s  Some further debugging of the RX path
is needed.

Finally, these parameters are likely not useful for the AR5212 era NICs.
The madwifi-dfs branch should have suitable example parameters for the
11a era NICs.

52c17430bc Current implementations of sync(2) and syncer vnode fsync() VOP uses
mnt_noasync counter to temporary remove MNTK_ASYNC mount option, which
is needed to guarantee a synchronous completion of the initiated i/o
before syscall or VOP return.  Global removal of MNTK_ASYNC option is
harmful because not only i/o started from corresponding thread becomes
synchronous, but all i/o is synchronous on the filesystem which is
initiated during sync(2) or syncer activity.

Instead of removing MNTK_ASYNC from mnt_kern_flag, provide a local
thread flag to disable async i/o for current thread only. Use the
opportunity to move DOINGASYNC() macro into sys/vnode.h and
consistently use it through places which tested for MNTK_ASYNC.

Some testing demonstrated 60-70% improvements in run time for the
metadata-intensive operations on async-mounted UFS volumes, but still
with great deviation due to other reasons.

68b6eb44b6 Make sound(4) more flexible in setting soft buffer and block sizes when
hardware imposes strict limitations on hard buffer and block sizes.

Previous code set soft buffer to be no smaller then hard buffer. On some
cards with fixed 64K physical buffer that caused up to 800ms play latency.
New code allows to set soft buffer size down to just two blocks of the hard
buffer and to not write more then that size ahead to the hardware buffer.
As result of that change I was able to reduce full practically measured
record-playback loop delay in those conditions down to only about 115ms
with theoretical playback latency of only about 50ms.

New code works fine for both vchans and direct cases. In both cases sound(4)
tries to follow hw.snd.latency_profile and hw.snd.latency values and
application-requested buffer and block sizes as much as limitation of two
hardware blocks allows.

replaces VOP_ACCESS(..VWRITE..) with one appropriate to
the lock operation. It allows unlock and lock cancellation
to be done without a check of VOP_ACCESS(), so that files

52801b5562 Add a DFS debugging mode which is useful when doing automated DFS
compliance testing.

In order to allow for radar pattern matching to occur, the DFS CAC/NOL
handling needs to be made configurable.  This commit introduces a new
sysctl, "net.wlan.dfs_debug", which controls which DFS debug mode
net80211 is in.

* 0 = default, CSA/NOL handling as per normal.
* 1 = announce a CSA, but don't add the channel to the non-occupy list
  (NOL.)
* 2 = disable both CSA and NOL - only print that a radar event occured.

This code is not compiled/enabled by default as it breaks regulatory
handling.  A user must enable IEEE80211_DFS_DEBUG in their kernel
configuration file for this option to become available.

read(2) has completed to purge just-read data.  The write(2) path continues

16da82cb91 As it turns out r227960 may still be insufficient with PREEMPTION
so try harder to get the CDMA sync interrupt delivered and also in
a more efficient way:
- wrap the whole process of sending and receiving the CDMA sync
  interrupt in a critical section so we don't get preempted,
- send the CDMA sync interrupt to the CPU that is actually waiting
  for it to happen so we don't take a detour via another CPU,
- instead of waiting for up to 15 seconds for the interrupt to
  trigger try the whole process for up to 15 times using a one
  second timeout (the code was also changed to just ignore belated
  interrupts of a previous tries should they appear).

According to testing done by Peter Jeremy with the debugging also
added as part of this commit the first two changes apparently are
sufficient to now properly get the CDMA sync interrupts delivered
at the first try though.

87d49c606e Fully disable interrupts while we fiddle with the FP context in the
VIS-based block copy/zero implementations. While with 4BSD it's
sufficient to just disable the tick interrupts, with ULE+PREEMPTION
it's otherwise also possible that these are preempted via IPIs.

59383c87dd Two changes from my DFS work:
* Grab the net80211com lock when calling ieee80211_dfs_notify_radar().
* Use the tsf extend function to turn the 64 bit base TSF into a per-
  frame 64 bit TSF.  This will improve radiotap logging (which will
  now have a (more) correct per-frame TSF, rather then the single TSF64
  value read at the beginning of ath_rx_proc().

1521eb4479 Avoid to check the same cache line/variable from all the locking
primitives by breaking stop_scheduler into a per-thread variable.
Also, store the new td_stopsched very close to td_*locks members as
they will be accessed mostly in the same codepaths as td_stopsched and
this results in avoiding a further cache-line pollution, possibly.

STOP_SCHEDULER() was pondered to use a new 'thread' argument, in order to
take advantage of already cached curthread, but in the end there should
not really be a performance benefit, while introducing a KPI breakage.

8ec59afebb Now that we have a working OF_printf() since r230631 and a OF_panic()
helper since r230632, use these for output and panicing during the
early cycles and move cninit() until after the static per-CPU data
has been set up. This solves a couple of issue regarding the non-
availability of the static per-CPU data:
- panic() not working and only making things worse when called,
- having to supply a special DELAY() implementation to the low-level
  console drivers,
- curthread accesses of mutex(9) usage in low-level console drivers
  that aren't conditional due to compiler optimizations (basically,
  this is the problem described in r227537 but in this case for
  keyboards attached via uart(4)). [1]

f3dd9013de For machines where the kernel address space is unrestricted increase
VM_KMEM_SIZE_SCALE to 2, awaiting more insight from alc@. As it turns
out, the VM apparently has problems with machines that have large holes
in the physical address space, causing the kmem_suballoc() call in
kmeminit() to fail with a VM_KMEM_SIZE_SCALE of 1. Using a value of 2
allows these, namely Blade 1500 with 2GB of RAM, to boot.
