A file cannot be deallocated until its last name has been removed
and it is no longer referenced by a user process. The inode for a
file whose name has been removed, but is still referenced at the
time of a crash will still be allocated in the filesystem, but will
have no references (e.g., they will have no names referencing them
from any directory).

With traditional soft updates these unreferenced inodes will be
found and reclaimed when the background fsck is run. When using
journaled soft updates, the kernel must keep track of these inodes
so that it can find and reclaim them during the cleanup process.
Their existence cannot be stored in the journal as the journal only
handles short-term events, and they may persist for days. So, they
are tracked by keeping them in a linked list whose head pointer is
stored in the superblock. The journal tracks them only until their
linked list pointers have been commited to disk. Part of the cleanup
process involves traversing the list of unreferenced inodes and
reclaiming them.

This bug was triggered when confusion arose in the commit steps
of keeping the unreferenced-inode linked list coherent on disk.
Notably, a race between the link() system call adding a link-count
to a file and the unlink() system call removing a link-count to
the file. Here if the unlink() ran after link() had looked up
the file but before link() had incremented the link-count of the
file, the file's link-count would drop to zero before the link()
incremented it back up to one. If the file was referenced by a
user process, the first transition through zero made it appear
that it should be added to the unreferenced-inode list when in
fact it should not have been added. If the new name created by
link() was deleted within a few seconds (with the file still
referenced by a user process) it would legitimately be a candidate
for addition to the unreferenced-inode list. The result was that
there were two attempts to add the same inode to the unreferenced-inode
list which scrambled the unreferenced-inode list's pointers leading
to a panic. The fix is to detect and avoid the false attempt at
adding it to the unreferenced-inode list by having the link()
system call check to see if the link count is zero before it
increments it. If it is, the link() fails with ENOENT (showing that
it has failed the link()/unlink() race).

While tracking down this bug, we have added additional assertions
to detect the problem sooner and also simplified some of the code.

This is a first cut at publishing heavily WIP work to port FreeBSD
64bit to run as a XEN paravirtualised kernel.

It is very early days and therefore only has a guarantee of
compilability on the branch. The following have been deferred for
later review:

 - style nits.
 - comments

What would be really helpful for review would be:
 - design errors
 - bugs
 - file organisation, API use etc.

The primary focus of the branch at this point is functionality.

We use a config(5) option:
options	 	NATIVE

to indicate "baremetal" support. The intent of this option is to
exclude files from the PV kernel that only the "baremetal" kernel
needs. This is similar to how the i386 port implements this. An
alternative method is needed before merge to -current

MFC r233231:
Fix several problems with our ELF filters implementation.

Do not relocate twice an object which happens to be needed by loaded
binary (or dso) and some filtee opened due to symbol resolution when
relocating need objects.  Record the state of the relocation
processing in Obj_Entry and short-circuit relocate_objects() if
current object already processed.

Do not call constructors for filtees loaded during the early
relocation processing before image is initialized enough to run
user-provided code.  Filtees are loaded using dlopen_object(), which
normally performs relocation and initialization.  If filtee is
lazy-loaded during the relocation of dso needed by the main object,
dlopen_object() runs too earlier, when most runtime services are not
yet ready.

Postpone the constructors call to the time when main binary and
depended libraries constructors are run, passing the new flag
RTLD_LO_EARLY to dlopen_object().  Symbol lookups callers inform
symlook_* functions about early stage of initialization with
SYMLOOK_EARLY.  Pass flags through all functions participating in
object relocation.

Use the opportunity and fix flags argument to find_symdef() in
arch-specific reloc.c to use proper name SYMLOOK_IN_PLT instead of
true, which happen to have the same numeric value.

MFC r233777 (by kan):
Do not try to adjust stacks if dlopen_object is called too early.

MFC r233778 (by kan):
Remove extra blank line from revious commit.

MFC note: the ARM and MIPS TLS support is not merged back, so the chunks
from r233231 which fix misuse of flags in calls to find_symdef() in
the corresponding relocation type handlers were not applied. When TLS
support is merged, the rest of r233231 should be applied too.

Since pf 4.5 import pf(4) has a mechanism to defer
forwarding a packet, that creates state, until
pfsync(4) peer acks state addition (or 10 msec
timeout passes).

This is needed for active-active CARP configurations,
which are poorly supported in FreeBSD and arguably
a good idea at all.

Unfortunately by the time of import this feature in
OpenBSD was turned on, and did not have a switch to
turn it off. This leaked to FreeBSD.

This change make it possible to turn this feature
off via ioctl() and turns it off by default.

MFC r230397, r230438, r232064:

MFC r230397 (pjd):
By default turn off prefetch when listing snapshots.
In my tests it makes listing snapshots 19% faster with cold cache and
47% faster with warm cache.

MFC r230438 (pjd):
Dramatically optimize listing snapshots when user requests only snapshot
names and wants to sort them by name, ie. when executes:

	# zfs list -t snapshot -o name -s name

Because only name is needed we don't have to read all snapshot properties.

Below you can find how long does it take to list 34509 snapshots from a single
disk pool before and after this change with cold and warm cache:

before:

	# time zfs list -t snapshot -o name -s name > /dev/null
	cold cache: 525s
	warm cache: 218s

after:

	# time zfs list -t snapshot -o name -s name > /dev/null
	cold cache: 1.7s
	warm cache: 1.1s

MFC r232064:

Simplify and enhance the window change/update acceptance logic,
especially in the presence of bi-directional data transfers.

snd_wl1 tracks the right edge, including data in the reassembly
queue, of valid incoming data.  This makes it like rcv_nxt plus
reassembly.  It never goes backwards to prevent older, possibly
reordered segments from updating the window.

snd_wl2 tracks the left edge of sent data.  This makes it a duplicate
of snd_una.  However joining them right now is difficult due to
separate update dependencies in different places in the code flow.

snd_wnd tracks the current advertized send window by the peer.  In
tcp_output() the effective window is calculated by subtracting the
already in-flight data, snd_nxt less snd_una, from it.

ACK's become the main clock of window updates and will always update
the window when the left edge of what we sent is advanced.  The ACK
clock is the primary signaling mechanism in ongoing data transfers.
This works reliably even in the presence of reordering, reassembly
and retransmitted segments.  The ACK clock is most important because
it determines how much data we are allowed to inject into the network.

Zero window updates get us out of persistence mode are crucial.  Here
a segment that neither moves ACK nor SEQ but enlarges WND is accepted.

When the ACK clock is not active (that is we're not or no longer
sending any data) any segment that moves the extended right SEQ edge,
including out-of-order segments, updates the window.  This gives us
updates especially during ping-pong transfers where the peer isn't
done consuming the already acknowledged data from the receive buffer
while responding with data.

The SSH protocol is a prime candidate to benefit from the improved
bi-directional window update logic as it has its own windowing
mechanism on top of TCP and is frequently sending back protocol ACK's.

  State expire time is a baseline time ("last active") for expiry
  calculations, and does _not_ denote the time when to expire.  So
  it should never be added to (set into the future).

  Try to reconstruct it with an educated guess on state import and
  just set it to the current time on state updates.

  This fixes a problem on pfsync listeners where the expiry time
  could be double the expected value and cause a lot more states
  to linger.

Correctly handle AR_MoreAggr when assembling multi-descriptor final frames.

Linux ath9k doesn't have this issue as it doesn't try queuing multi-
descriptor frames to the hardware.

Before, I was only setting the first and last descriptor in the final
frame correctly - and that was done by accident. The first descriptor in
the last sub-frame was being correctly updated by ath_tx_setds_11n();
the last descriptor in the last sub-frame was being correctly updated
by ath_buf_set_rate(). But both of those are "incorrect".

The correct behaviour is:

* AR_IsAggr is set for all descriptors for all subframes in an aggregate.
* AR_MoreAggr is set for all descriptors for all non-final sub-frames
  in an aggregate.

Ie, all descriptors in the last sub-frame of an aggregate must have this
field set to 0.

I still need to do a couple of extra passes to ensure the pad delimiter
field is being correctly handled in all descriptors in the last sub-frame.

Implement BAR TX.

A BAR frame must be transmitted when an frame in an A-MPDU session fails
to transmit - it's retried too often, or it can't be cloned for
re-transmission.  The BAR frame tells the remote side to advance the
left edge of the block-ack window (BAW) to a new value.

In order to do this:

* TX for that particular node/TID must be paused;
* The existing frames in the hardware queue needs to be completed, whether
  they're TXed successfully or otherwise;
* The new left edge of the BAW is then communicated to the remote side
  via a BAR frame;
* Once the BAR frame has been sucessfully TXed, aggregation can resume;
* If the BAR frame can't be successfully TXed, the aggregation session
  is torn down.

This is a first pass that implements the above.  What needs to be done/
tested:

* What happens during say, a channel reset / stuck beacon _and_ BAR
  TX.  It _should_ be correctly buffered and retried once the
  reset has completed.  But if a bgscan occurs (and they shouldn't,
  grr) the BAR frame will be forcibly failed and the aggregation session
  will be torn down.

  Yes, another reason to disable bgscan until I've figured this out.

* There's way too much locking going on here.  I'm going to do a couple
  of further passes of sanitising and refactoring so the (re) locking
  isn't so heavy.  Right now I'm going for correctness, not speed.

* The BAR TX can fail if the hardware TX queue is full.  Since there's
  no "free" space kept for management frames, a full TX queue (from eg
  an iperf test) can race with your ability to allocate ath_buf/mbufs
  and cause issues.  I'll knock this on the head with a subsequent
  commit.

* I need to do some _much_ more thorough testing in hostap mode to ensure
  that many concurrent traffic streams to different end nodes are correctly
  handled.  I'll find and squish whichever bugs show up here.

But, this is an important step to being able to flip on 802.11n by default.
The last issue (besides bug fixes, of course) is HT frame protection and
I'll address that in a subsequent commit.

umtx operation UMTX_OP_MUTEX_WAKE has a side-effect that it accesses
a mutex after a thread has unlocked it, it event writes data to the mutex
memory to clear contention bit, there is a race that other threads
can lock it and unlock it, then destroy it, so it should not write
data to the mutex memory if there isn't any waiter.
The new operation UMTX_OP_MUTEX_WAKE2 try to fix the problem. It
requires thread library to clear the lock word entirely, then
call the WAKE2 operation to check if there is any waiter in kernel,
and try to wake up a thread, if necessary, the contention bit is set again
by the operation. This also mitgates the chance that other threads find
the contention bit and try to enter kernel to compete with each other
to wake up sleeping thread, this is unnecessary. With this change, the
mutex owner is no longer holding the mutex until it reaches a point
where kernel umtx queue is locked, it releases the mutex as soon as
possible.
Performance is improved when the mutex is contensted heavily.  On Intel
i3-2310M, the runtime of a benchmark program is reduced from 26.87 seconds
to 2.39 seconds, it even is better than UMTX_OP_MUTEX_WAKE which is
deprecated now. http://people.freebsd.org/~davidxu/bench/mutex_perf.c

- Improve BPF locking model.

Interface locks and descriptor locks are converted from mutex(9) to rwlock(9).
This greately improves performance: in most common case we need to acquire 1
reader lock instead of 2 mutexes.

- Remove filter(descriptor) (reader) lock in bpf_mtap[2]
This was suggested by glebius@. We protect filter by requesting interface
writer lock on filter change.

- Cover struct bpf_if under BPF_INTERNAL define. This permits including bpf.h
without including rwlock stuff. However, this is is temporary solution,
struct bpf_if should be made opaque for any external caller.

- Improve performace for writer-only BPF users.

Linux and Solaris (at least OpenSolaris) has PF_PACKET socket families to send
raw ethernet frames. The only FreeBSD interface that can be used to send raw frames
is BPF. As a result, many programs like cdpd, lldpd, various dhcp stuff uses
BPF only to send data. This leads us to the situation when software like cdpd,
being run on high-traffic-volume interface significantly reduces overall performance
since we have to acquire additional locks for every packet.

Here we add sysctl that changes BPF behavior in the following way:
If program came and opens BPF socket without explicitly specifyin read filter we
assume it to be write-only and add it to special writer-only per-interface list.
This makes bpf_peers_present() return 0, so no additional overhead is introduced.
After filter is supplied, descriptor is added to original per-interface list permitting
packets to be captured.

Unfortunately, pcap_open_live() sets catch-all filter itself for the purpose of
setting snap length.

Fortunately, most programs explicitly sets (event catch-all) filter after that.
tcpdump(1) is a good example.

So a bit hackis approach is taken: we upgrade description only after second
BIOCSETF is received.

Sysctl is named net.bpf.optimize_writers and is turned off by default.

- While here, document all sysctl variables in bpf.4

retrofit Safe Mode loader menu item actions

The menu item is now made completely independent with the ACPI item - most
modern systems seem to require ACPI and become even more "unsafe"
without it.
Safe Mode no longer disables APIC for the same reason.
kbdmux is not disabled as this feature has proven itself stable.

New actions:
- SMP is disabled in the Safe Mode now
- eventtimers are forced to periodic mode (some real and virtual systems
  seem to have problems otherwise)
- geom extra vigorous integrity checking is disabled, this is to
  facilitate migration from previous versions

Possible short term to do:
- make SMP switch a separate menu item
- restore APIC switch as a separate menu item

Longer term to do:
- turn various tweaks into separate menu items in a Safe Mode sub-menu

Please consider adding a safety tweak to Safe Mode when introducing
new major features or changes that may cause instabilities.

	Since "intr_cpus" is statically initialized to the empty set, and
	all processors, including the BSP, already add themselves to
	"intr_cpus" no special initialization for the BSP is necessary.

On some devices MMC controller numbering starts from 0.
Also it is unreliable to enable clocks based on device_get_unit().

Change the SCSI INQUIRY peripheral qualifier that CTL reports for LUNs
that don't exist.

Anecdotal evidence indicates that it is better to return 011b (bad LUN)
than 001b (LUN offline).  However, this change also gives the user a
sysctl/tunable, kern.cam.ctl.inquiry_pq_no_lun, to override the change
and return to the previous behavior.  (The previous behavior was to
return 001b, or LUN offline.)

ctl.c:		Change the default inquiry peripheral qualifier to 011b,
		and add a sysctl and tunable to allow the user to change
		it back to 001b if needed.

		Don't insert a Copan copyright statement in the inquiry
		data.  The copyright statements on the files are
		sufficient.

ctl_private.h:	Add sysctl variable context to the CTL softc.

ctl_cmd_table.c,
ctl_frontend_internal.c,
ctl_frontend.c,
ctl_backend.c,
ctl_error.c:	Include sys/sysctl.h.

Store away the RTS aggregate limit from the HAL.

This will be used by some upcoming code to ensure that aggregates
are enforced to be a certain size.  The AR5416 has a limitation on
RTS protected aggregates (8KiB).

Enforce the RTS aggregation limit if RTS/CTS protection is enabled;
if any subframes in an aggregate have different protection from the
first frame in the formed aggregate, don't add that frame to the
aggregate.

This is likely a suboptimal method (I think we'll mostly be OK marking
frames that have seqno's with the same protection as normal data frames)
but I'll just be cautious for now.

Fix a bug in remquo{,f,l}, in which the quotient didn't always have the
correct sign when the remainder was 0.

Fix a separate bug in remquo alone, in which the remainder and
quotient were both off by a bit in certain cases involving subnormal
remainders.

The bugs affected all platforms except amd64 and i386, on which the
routines are implemented in assembly.
