ef17620fc8 MFV r245512:
* Illumos zfs issue #3035 [1] LZ4 compression support in ZFS.

LZ4 is a new high-speed BSD-licensed compression algorithm created
by Yann Collet that delivers very high compression and decompression
performance compared to lzjb (>50% faster on compression, >80% faster
on decompression and around 3x faster on compression of incompressible
data), while giving better compression ratio [1].

This version of LZ4 corresponds to upstream's [2] revision 85.

Please note that for obvious reasons this is not backward read
compatible.  This means once a pool have LZ4 compressed data, these
data can no longer be read by older ZFS implementations.

Local changes:

 - On-stack hash table disabled and using kernel slab allocator
   instead, at this time.  This requires larger kernel thread stack
   for zio workers.  This may change in the future should we adjusted
   the zio workers' thread stack size.
 - likely and unlikely will be undefined if they are already defined,
   this is required for i386 XEN build.
 - Removed De Bruijn sequence based __builtin_ctz family of builtins
   in favor of the latter.  Both GCC and clang supports these builtins.
 - Changed the way the LZ4 code detects endianness.
 - Manual pages modifications to mention the feature based on Illumos
   counterpart.
 - Boot loader changes to make it support LZ4 decompression.

1a125d6d85 ext2fs: make e2fs_maxcontig local and remove tautological check.
e2fs_maxcontig was modelled after UFS when bringing the
"Orlov allocator" to ext2. On UFS fs_maxcontig is kept in the
superblock and is used by userland tools (fsck and growfs),

In ext2 this information is volatile so it is not available
for userland tools, so in this case it doesn't have sense
to carry it in the in-memory superblock.

Also remove a pointless check for MAX(1, x) > 0.

d03904f1db Fix a corner case that I noticed with the AR5416 (and it's currently
crappy 802.11n performance, sigh.)

With the AR5416, aggregates need to be limited to 8KiB if RTS/CTS is
enabled.  However, larger aggregates were going out with RTSCTS enabled.
The following was going on:

* The first buffer in the list would have RTS/CTS enabled in
  bf->bf_state.txflags;
* The aggregate would be formed;
* The "copy over the txflags from the first buffer" logic that I added
  blanked the RTS/CTS TX flags fields, and then copied the bf_first
  RTS/CTS flags over;
* .. but that'd cause bf_first to be blanked out! And thus the flag
  was cleared;
* So the rest of the aggregate formation would run with those flags
  cleared, and thus > 8KiB aggregates were formed.

The driver is now (again) correctly limiting aggregate formation for
the AR5416 but there are still other pending issues to resolve.

Tested:

* AR5416, STA mode

4c4f4aa0f3 HWMP: ic->raw_xmit didn't always point to correct ni.
This is a code re-write. ic->raw_xmit need a pointer to ieee80211_node
for the destination node (da). I have reorganized the code so that
a pointer to the da node is searched for in the end & in one place.

* Make mesh_find_txnode public to be used by HWMP, renamed to
  ieee80211_mesh_finx_txnode;
* changed the argument from ieee80211_node to ieee80211vap for all
  hwmp_send_* functions;
* removed the 'sa' argument from hwmp_send_* functions as all HWMP frames
  have the source address equal to vap->iv_myaddr;
* Modified hwmp_send_action so that if da is MULTCAST ni=vap->iv_bss
  otherwise we called ieee80211_mesh_find_txnode. Also no need to hold
  a reference in this functions if da is not MULTICAST as by finding the
  node it became referenced in ieee80211_find_txnode;

ed0b544066 Mesh update: add base Mesh Gate functionality.
A Mesh Gate should transmit a Mesh Action frame containing
ieee80211_meshgann_ie as its only information element periodically
every ieee80211_mesh_gateint ms. Unless the mesh gate is also configure
as a ROOT, then these frames should not be send.
This is according to 802.11 2012 standard;

* Introduce new SYSCTL net.wlan.mesh.gateint, with 10s default;
* Add two new functions mesh_gatemode_setup and mesh_gatemode_cb. This
  is similar to how HWMP setups up a callout;
* Add two new action handlers mesh_recv_action_meshgate and
  mesh_send_action_meshgate;
* Added ieee80211_add_meshgate to ieee80211_mesh.h;
* Modified mesh_send_action to look similar to hwmp_send_action. This is
  because we need to send out broadcast management frames.
* Introduced a new flag for mesh state IEEE80211_MESHFLAGS_ROOT. This flag
  is now set by HWMP code when a mesh STA is configured as a ROOT. This
  is then checked by mesh_gatemode_cb before scheduling a new callout;
* Added to new field to ieee80211_mesh_state:
    + struct callout                  ms_gatetimer

888d4d4f86 When vforked child is traced, the debugging events are not generated
until child performs exec().  The behaviour is reasonable when a
debugger is the real parent, because the parent is stopped until
exec(), and sending a debugging event to the debugger would deadlock
both parent and child.

On the other hand, when debugger is not the parent of the vforked
child, not sending debugging signals makes it impossible to debug
across vfork.

Fix the issue by declining generating debug signals only when vfork()
was done and child called ptrace(PT_TRACEME).  Set a new process flag
P_PPTRACE from the attach code for PT_TRACEME, if P_PPWAIT flag is
set, which indicates that the process was created with vfork() and
still did not execed. Check P_PPTRACE from issignal(), instead of
refusing the trace outright for the P_PPWAIT case.  The scope of
P_PPTRACE is exactly contained in the scope of P_PPWAIT.

ded5ea6a25 This fixes a out-of-order problem with several
of the newer drivers. The basic problem was
that the driver was pulling the mbuf off the
drbr ring and then when sending with xmit(), encounting
a full transmit ring. Thus the lower layer
xmit() function would return an error, and the
drivers would then append the data back on to the ring.
For TCP this is a horrible scenario sure to bring
on a fast-retransmit.

The fix is to use drbr_peek() to pull the data pointer
but not remove it from the ring. If it fails then
we either call the new drbr_putback or drbr_advance
method. Advance moves it forward (we do this sometimes
when the xmit() function frees the mbuf). When
we succeed we always call advance. The
putback will always copy the mbuf back to the top
of the ring. Note that the putback *cannot* be used
with a drbr_dequeue() only with drbr_peek(). We most
of the time, in putback, would not need to copy it
back since most likey the mbuf is still the same, but
sometimes xmit() functions will change the mbuf via
a pullup or other call. So the optimial case for
the single consumer is to always copy it back. If
we ever do a multiple_consumer (for lagg?) we
will  need a test and atomic in the put back possibly
a seperate putback_mc() in the ring buf.

a120a7a3cd Rework the handling of stop signals in the NFS client. The changes in
195702, 195703, and 195821 prevented a thread from suspending while holding
locks inside of NFS by forcing the thread to fail sleeps with EINTR or
ERESTART but defer the thread suspension to the user boundary.  However,
this had the effect that stopping a process during an NFS request could
abort the request and trigger EINTR errors that were visible to userland
processes (previously the thread would have suspended and completed the
request once it was resumed).

This change instead effectively masks stop signals while in the NFS client.
It uses the existing TDF_SBDRY flag to effect this since SIGSTOP cannot
be masked directly.  Also, instead of setting PBDRY on individual sleeps,
the NFS client now sets the TDF_SBDRY flag around each NFS request and
stop signals are masked for all sleeps during that region (the previous
change missed sleeps in lockmgr locks).  The end result is that stop
signals sent to threads performing an NFS request are completely
ignored until after the NFS request has finished processing and the
thread prepares to return to userland.  This restores the behavior of
stop signals being transparent to userland processes while still
preventing threads from suspending while holding NFS locks.

If NKPT is defined in the kernel configuration file then it overrides the

088dd4b78a Rework jumbo frame handling. QAC confirmed that the controller
requires 8 bytes alignment on RX buffer.  Given that non-jumbo
frame works on any alignments I guess this DMA limitation for RX
buffer could be jumbo frame specific one.  Also I'm not sure
whether this DMA limitation is related with 64bit DMA.  Previously
age(4) disabled 64bit DMA addressing due to silent data corruption.
So we may need more testing on re-enabling 64bit DMA in future.

While I'm here, change mbuf chaining algorithm to use fixed sized
buffer and force software checksum if controller reports length
error. According to QAC, RFD is not updated at all for jumbo frame
so it works just like alc(4) controllers.  This change also added
alignment fixup for strict alignment architectures.  Because I'm
not aware of any non-x86 machines that use age(4) controllers it's
just for completeness at this moment.

Wit this change, jumbo frame should work with age(4).

c7d346f269 zfs: fix, improve and re-organize page_lookup and page_unlock
Now they are split into two pairs: page_hold/page_unhold for mappedread
and page_busy/page_unbusy for update_pages.

For mappedread we simply hold a page that is to be used as a source if it
is resident and valid (and not busy).  This is sufficient since we are
only doing page -> user buffer copying.  There is no page <-> backing
storage I/O involved.

update_pages is now better split to properly handle the putpages case
(page -> arc) and the regular write case (arc -> page).

For the latter we use complete protocol of marking an object with
paging-in-progress and marking a page with io_start (busy count).
Also, in this case we remove the write bit from all page mappings and
clear dirty bits of the pages, the former is needed to ensure that the
latter does the right thing.
Additionally we update a page if it is cached instead of just freeing it
as was done before.  This needs to be verified.

A minor detail: ZFS-backed pages should always be either fully valid
or fully invalid.  Assert this and use simpler API that does not deal
with sub-page blocks.

9ec062dddd The directory entry for dotdot was corrupted in the FAT32 case when moving
a directory to a subdir of the root directory from somewhere else.

For all directory moves that change the parent directory, the dotdot
entry must be fixed up.  For msdosfs, the root directory is magic for
non-FAT32.  It is less magic for FAT32, but needs the same magic for
the dotdot fixup.  It didn't have it.

Both chkdsk and fsck_msdosfs fix the corrupt directory entries with no
problems.

The fix is to use the same magic for dotdot in msdosfs_rename() as in
msdosfs_mkdir().

For msdosfs_mkdir(), document the magic. When writing the dotdot entry
in mkdir, use explicitly set pcl variable instead on relying on the
start cluster of the root directory typically has a value < 65536.

48efa33b49 The mountmsdosfs() function had an insane sanity test, remove it.
Trying FAT32 on a small partition failed to mount because
pmp->pm_Sectors was nonzero.  Normally, FAT32 file systems are so
large that the 16-bit pm_Sectors can't hold the size.  This is
indicated by setting it to 0 and using only pm_HugeSectors.  But at
least old versions of newfs_msdos use the 16-bit field if possible,
and msdosfs supports this except for breaking its own support in the
sanity check.  This is quite different from the handling of pm_FATsecs
-- now the 16-bit value is always ignored for FAT32 except for
checking that it is 0, and newfs_msdos doesn't use the 16-bit value
for FAT32.

8caac1d5ba Delete the "blackhole" driver - it is not needed anymore.
The "blackhole" driver was used in conjunction with bhyve to sequester
pci devices intended for passthru until vmm.ko was loaded. This was
useful at one point because vmm.ko could not be loaded at boot time.

The same functionality can now be achieved by loading vmm.ko via the
loader along with the kernel.

2b89a04496 Fix a broken assumption in the passthru implementation that the MSI-X table
can only be located at the beginning or the end of the BAR.

If the MSI-table is located in the middle of a BAR then we will split the
BAR into two and create two mappings - one before the table and one after
the table - leaving a hole in place of the table so accesses to it can be
trapped and emulated.

07044a96d8 Increase the number of passthru devices supported by bhyve.
The maximum length of an environment variable puts a limitation on the
number of passthru devices that can be specified via a single variable.
The workaround is to allow user to specify passthru devices via multiple
environment variables instead of a single one.

9711a168b9 Retire struct sockaddr_inarp.
Since ARP and routing are separated, "proxy only" entries
don't have any meaning, thus we don't need additional field
in sockaddr to pass SIN_PROXY flag.

New kernel is binary compatible with old tools, since sizes
of sockaddr_inarp and sockaddr_in match, and sa_family are
filled with same value.

The structure declaration is left for compatibility with
third party software, but in tree code no longer use it.

b8f355bf50 Work around some rather unfortunate race conditions inside net80211.
Right now, ic_curchan seems to be updated rather quickly (ie, during
the ioctl) and before the driver gets notified of what's going on.
So what I was seeing was:

* NIC was in channel X;
* It generates PHY errors for channel X;
* an ioctl comes along from userland and changes things to channel Y;
* .. this updates ic_curchan, but hasn't yet reset the hardware;
* in parallel, RX is occuring and it looks at ic_curchan;
* .. which is channel Y, so events get stamped with that now.

Sigh.

d2b99310b1 Modify the FreeBSD USB kernel code so that it can be compiled directly
into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems
or embedded platforms. This is also useful for out of the system compilation
of the FreeBSD USB stack for various purposes. The USB kernel files can
now optionally include a global header file which should include all needed
definitions required to compile the FreeBSD USB stack. When the global USB
header file is included, no other USB header files will be included by
default.

Add new file containing the USB stack configuration for the
FreeBSD loader build.

Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all
USB files follow the same style.

Use cases:
 - console in loader via USB
 - loading kernel via USB

82c3d173cc Reduce default shift used to calculate the max frequency for the TSC
timecounter to 1, and correspondingly increase the precision of the
gettimeofday(2) and related functions in the default configuration.

The motivation for the TSC-low timecounter, as described in the
r222866, seems to provide a workaround for the non-serializing
behaviour of the RDTSC on some Intel hardware.  Tests demonstrate that
even with the pre-shift of 8, the cross-core non-monotonicity of the
RDTSC is still observed reliably, e.g. on the Nehalems.  The r238755
and r238973 implemented the proper fix for the issue.

The pre-shift of 1 is applied to keep TSC not overflowing for the
frequency of hardclock down to 2 sec/intr.  The pre-shift is made a
tunable to allow the easy debugging of the issues users could see with
the shift being too low.

32c7ac38ed Fix off-by-one errors in low-level arm9 and arm10 cache maintenance routines.
In all the routines that loop through a range of virtual addresses, the loop
is controlled by subtracting the cache line size from the total length of the
request.  After the subtract, a 'bpl' instruction was used, which branches if
the result of the subtraction is zero or greater, but we need to exit the
loop when the count hits zero.  Thus, all the bpl instructions in those loops
have been changed to 'bhi' (branch if greater than zero).

In addition, the two routines that walk through the cache using set-and-index
were correct, but confusing.  The loop control for those has been simplified,
just so that it's easier to see by examination that the code is correct.

Routines for other arm architectures and generations still have the bpl
instruction, but compensate for the off-by-one situation by decrementing
the count register by one before entering the loop.

d71a1f7ae4 Initial cut at making IBSS support 802.11n aware.
* Add HTINFO field decoding to ieee80211_ies_expand() - it's likely not
  100% correct as it's not looking at the draft 11n HTINFO location,
  but I don't think anyone will care.

* When doing an IBSS join make sure the 11n channel configuration
  is used - otherwise the 11a/11bg channel will be used
  and there won't be any chance for an upgrade to 11n.

* When creating an IBSS network, ensure the channel is updated to an
  11n channel so other 11n nodes can see it and speak to it with MCS
  rates.

* Add a bit of code that's disabled for now which handles the HT
  field updating.  This won't work out very well with lots of adhoc
  nodes as we'd end up ping-ponging between the HT configuration for
  each node.  Instead, we should likely only pay attention to the
  "master" node we initially associated against and then ensure we
  propagate that information forward in our subsequent beacons.  However,
  due to the nature of IBSS (ie, there's no specific "master" node in
  the specification) it's unclear which node we should lift the HT
  parameters from.

  So for now this assumes the HT parameters are squirreled away in the
  initial beacon/probe response.

So there's some trickiness here.

With ap/sta pairing, the probe response just populates a legacy node
and the association request/response is what is used for negotiation
11n-ness (and upgrading things as needed.)

With ibss networks, the pairing is done with probe request/response,
with discovery being done by creating nodes when new beacons in the
IBSS / BSSID are heard.  There's no assoc request/response frames going on.

So the trick here has been to figure out where to upgrade things.
I don't like how I just taught ieee80211_sta_join() to "speak" HT -
I'd rather there be an upgrade path when an IBSS node joins and there
are HT parameters present.  Once I've done that, I'll kill this
HT special casing that's going on in ieee80211_sta_join().

Tested:

* AR9280, AR5416, AR5212 - basic iperf and ping interoperability tests
  whilst in a non-encrypted adhoc network.

TODO:

* Fix up the HT upgrade path for IBSS nodes rather than adding code
  in ieee80211_sta_join(), then remove my code from there.

* When associating, there's a concept of a "master" node in the IBSS
  which is the node you first joined the network through.  It's possible
  the correct thing to do is to listen to HT updates and configure WME
  parameters from that node.  However, once that node goes away, which
  node(s) should be listened to for configuration changes?

  For things like HT channel width, it's likely going to be ok to
  just associate as HT40 and then use the per-neighbor rate control
  and HTINFO/HTCAP fields to figure out which rates and configuration
  to speak.  Ie, for a 20MHz 11n node, just speak 20MHz rates to
  it.  It shouldn't "change", like what goes on in AP/STA configurations.

f28a552089 Migrate the TX sending code out from under the ath0 taskq and into
the separate ath0 TX taskq.

Whilst here, make sure that the TX software scheduler is also
running out of the TX task, rather than the ath0 taskqueue.

Make sure that the tx taskqueue is blocked/unblocked as necessary.

This allows for a little more parallelism on multi-core machines,
as well as (eventually) supporting a higher task priority for TX
tasks, allowing said TX task to preempt an already running RX or
TX completion task.

Tested:

* AR5416, AR9280 hostap and STA modes

- Sanitize bge_probe() a bit (don't hardcode buffer sizes, allow
  bge_lookup_vendor() to return NULL so the excessive panic() three
  can be removed there, etc.) and return BUS_PROBE_DEFAULT rather than
  hardcoding 0.

4364ec0852 Move lle_event to if_llatbl.h
lle_event replaced arp_update_event after the ARP rewrite and ended up
in if_ether.h simply because arp_update_event used to be there too.
IPv6 neighbor discovery is going to grow lle_event support and this is a
good time to move it to if_llatbl.h.

The two in-tree consumers of this event - OFED and toecore - are not

718c2b5b11 Revert the part of r239864 which removed obtaining the SMP mutex around
reading registers from other CPUs. As it turns out, the hardware doesn't
really like concurrent IPI'ing causing adverse effects. Also the thought
deadlock when using this spin lock here and the targeted CPU(s) are also
holding or in case of nested locks can't actually happen. This is due to
the fact that on sparc64, spinlock_enter() only raises the PIL but doesn't
disable interrupts completely. Thus direct cross calls as used for the
register reading (and all other MD IPI needs) still will be executed by
the targeted CPU(s) in that case.

091fd0ab54 Add support for transparent mode while in netmap.
By setting dev.netmap.fwd=1 (or enabling the feature with a per-ring flag),
packets are forwarded between the NIC and the host stack unless the
netmap client clears the NS_FORWARD flag on the individual descriptors.

This feature greatly simplifies applications where some traffic
(think of ARP, control traffic, ssh sessions...) must be processed
by the host stack, whereas the bulk is handled by the netmap process
which simply (un)marks packets that should not be forwarded.
The default is chosen so that now a netmap receiver operates
in a mode very similar to bpf.

Of course there is no free lunch: traffic to/from the host stack
still operates at OS speed (or less, as there is one extra copy in
one direction).
HOWEVER, since traffic goes to the user process before being
reinjected, and reinjection occurs in a user context, you get some
form of livelock protection for free.
