88bb82e511 Do not create a hardware IPv6 server if the listen address is not
in6addr_any and is not in the CLIP table either.  This fixes a reported
TOE+IPv6 NULL-dereference panic in do_pass_open_rpl().

While here, stop creating hardware servers for any loopback address.
It's just a waste of server tids.

4c631db3cc Fix several panics when initialization of an ISA or PC-CARD device fails:
o  Assign sc->an_dev in an_probe() (which isn't really a probe function in
   the standard newbus sense) as we may need it for printing errors.
o  Use device_printf() rather than if_printf() in an_reset() - this is
   called from an_probe() long before the ifp structure is initialised
   in an_attach().
o  Initialize the ifp structure early in an_attach() as we use if_printf()
   in cases where allocation of descriptors etc fails.

sys/cdefs.h.  In particular, in case of COMPAT_43, param.h includes
sys/types.h, which includes sys/select.h, which includes
sys/_sigset.h.  The _sigset.h customizes the provided definions based
on COMPAT_43, eliminating osigset_t if symbol is not defined.  The
sys/proc.h is included after opt_compat.h and needs osigset_t.

Move opt_compat.h inclusion into the right place.

Make the scan state optional - we'll obviously need a vap, but we now

92d7ab9562 Begin fleshing out some code to handle tracking PLCP error rates
in preparation for the scan based retune logic.

The linux iwlwifi driver does a rescan (onto a non-active channel)
to force an RF retune when the PLCP error rates exceed a certain threshold.

* Add code to track HT PLCP rate errors;
* Separate out the PLCP error count fetch and update so the delta
  can be used when checking for PLCP error rates;
* Implement the PLCP error logic from iwlwifi;
* For now, just print out whenever the error rate exceeds the
  threshold.

The actual scan based retune will take a bit more effort; the scan
command code right now assumes that a scan state is passed in.
This does need to change to be more flexible (both for this and
in preparation for scanning multiple channels at once.)

* 5100 (STA mode)

fee842aa2a Overhaul the iwn(4) scan infrastructure to be slightly more "correct"
for these chipsets.

* Correctly set the active/passive flag in the scan request - this is
  NOT a "is the channel active|passive"; it's to do with whether we
  have an SSID to actively scan for or not.  The firmware takes care
  of the active/passive setup of the channel.

* Calculate the active/passive dwell time based on the beacon interval
  and the channel mode, rather than using a hard coded value.

* For now, hardcode the scan service_time.  It's defined as:

  31:22 - number of beacon intervals to come back onto the home channel
          for;
  0:21  - time (microseconds) to come back onto the home channel for.

  When doing an active scan when the NIC is active (whether we're associated
  or not - it only matters if we've setup the NIC to a destination or not)
  this determines how much time to stay on the home channel for when
  scanning.  We can tune this based on the amount of active traffic.

  For now it's 4 beacon intervals and 100 microseconds.

* Fix the "good crc threshold" setting.  It differs based on the NIC
  firmware.  Some older firmware required a workaround; the later
  firmware instead treats the field as a flag.

* Enforce that we are not sending a scan command if one is already
  pending.  Any time this is done is a bug and it absolutely needs
  to be fixed - so be very loud.

* Add the SCAN flag to a few debug messages that are scan related but
  only occuring under STATE.

Now, this does get noisy when you're scanning in an actively busy 2GHz
network as the firmware (for reason I don't quite yet understand) seems
hell bent on staying on some passive channels longer than it should.
However, it should eventually recover and complete the scan.

This is a work in progress; please let me know if things get stuck or
if things improve!

c6f810c6a4 Add some code to double-check whether we're correctly populating the
TX ring according to what the firmware requires.

The firmware requires A-MPDU sub-frames to be at a very specific ring
offset - that is, the ring slot offset should be (seqno % 256.)

This holds for every NIC I've tested thus far except the 4965,
which starts erroring out here shortly before the firmware panics.
Which is good, it's doing what it's supposed to (read: capture that
we've screwed up somewhere.)

The specifics about getting this stuff right:

* the initial seqno allocation should match up with the ringid.
* .. yes, this means we can start at a ring offset that isn't zero.
* .. because we program the start seqno in the firmware message
  to setup the AC.
* The initial seqno allocation may be non-zero _and_ frames may be
  being transmitted during a-mpdu negotiation.  I faced similar
  issues on ath(4) and had to software queue frames to that node+TID
  during A-MPDU negotiation.
* seqno allocation should be in lockstep with ring increments.
* If we fail to transmit some segment, no, we shouldn't reuse that
  ring slot.  We should just transmit a BAR (which we aren't yet
  doing, sigh) and move onto the next seqno.
* In theory there shouldn't be any holes in the seqno space when
  we are transmitting frames.

Tested:

* 4965 (throws problems, so yes we have to fix this);
* 5100 (seems ok);
* 6200 (seems ok);
* 2200 (seems ok);
* 2230 (seems ok).

7a22215c53 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

1eafa5d8b0 drm: Dereference pointers given to qsort_r()'s cmp callback
drm_le_cmp() (qsort_r()'s callback) receives pointers to elements in the
array passed to qsort_r(), not the elements themselves.

Before this fix, the use of qsort_r() shuffled the array, not sorted it,
because the compare callback accessed random memory locations, not the
expected elements.

This bug triggered an infinite loop in KDE/xserver:

    1. KDE has a kded module called "randrmonitor" which queries xserver
       for current monitors at startup and then listens to RandR
       notifications from xserver.

    2. xserver handles the query from "randrmonitor" by polling the
       video device using the "drm_mode_getconnector()" ioctl. This
       ioctl returns a list of connectors and, for those with a
       connected monitor, the available modes. Each modes list is sorted
       by the kernel before returning. When xserver gets the connectors
       list, it sorts the modes lists again.

       In the case of this bug, when two modes are equal (in xserver's
       compare function PoV), their order is kept stable (ie. the
       kernel order is kept for those two modes). And because the list
       was shuffled by the kernel, the order of two equal modes was
       frequently changed in the final modes list in xserver.

    3. xserver compares the returned connectors list with the list
       obtained earlier. In particular, it compares the sorted
       modes lists for each connector. If a property of a connector
       changes (eg. modes), xserver sends a "RRNotify_OutputChange"
       notification.

       Because of the change of order between equal modes, xserver sent
       a notification after each polling of the connectors.

    4. "randrmonitor" receives a notification, triggered by its query. The
       notification doesn't contain the new connectors list, therefore, it
       asks for the new list using the same function: go back to step #2.

54366c0bd7 - For kernel compiled only with KDTRACE_HOOKS and not any lock debugging
option, unbreak the lock tracing release semantic by embedding
  calls to LOCKSTAT_PROFILE_RELEASE_LOCK() direclty in the inlined
  version of the releasing functions for mutex, rwlock and sxlock.
  Failing to do so skips the lockstat_probe_func invokation for
  unlocking.
- As part of the LOCKSTAT support is inlined in mutex operation, for
  kernel compiled without lock debugging options, potentially every
  consumer must be compiled including opt_kdtrace.h.
  Fix this by moving KDTRACE_HOOKS into opt_global.h and remove the
  dependency by opt_kdtrace.h for all files, as now only KDTRACE_FRAMES
  is linked there and it is only used as a compile-time stub [0].

[0] immediately shows some new bug as DTRACE-derived support for debug
in sfxge is broken and it was never really tested.  As it was not
including correctly opt_kdtrace.h before it was never enabled so it
was kept broken for a while.  Fix this by using a protection stub,
leaving sfxge driver authors the responsibility for fixing it
appropriately [1].

NIC and pushed up to the driver.  Unfortunately this means there's
no rate control notification done.  Thus, if the rate control code
makes a decision that hits a crappy rate that can't succeed, the
rate code would never lower the rate and packet loss would continue.

4c85fcfa37 On XenServer the "halt" message is used instead of "poweroff", which
makes FreeBSD halt but not poweroff (as expected when issuing a
shutdown from the VM manager). Fix this by using the same handler
for both "halt" and "poweroff".

NB: The "halt" signal seems to be used on XenServer only.  The OSS
    Xen toolstack (xl) uses "poweroff" instead.

fdtbus in most cases. This brings ARM and MIPS more in line with existing
Open Firmware platforms like sparc64 and powerpc, as well as preventing
double-enumeration of the OF tree on embedded PowerPC (first through nexus,
then through fdtbus).

This change is also designed to simplify resource management on FDT platforms
by letting there exist a platform-defined root bus resource_activate() call
instead of replying on fdtbus to do the right thing through fdt_bs_tag.
The OFW_BUS_MAP_INTR() and OFW_BUS_CONFIG_INTR() kobj methods are also

- some new features in the pkt-gen test program

(NETMAP_API has been bumped so you will detect old binaries at runtime).

In particular:
- struct netmap_slot now is 16 bytes to support an extra pointer,
  which may save one data copy when using VALE ports or VMs;

86be9f0dd5 Import the driver for VT-d DMAR hardware, as specified in the revision
1.3 of Intelб╝ Virtualization Technology for Directed I/O Architecture
Specification.  The Extended Context and PASIDs from the rev. 2.2 are
not supported, but I am not aware of any released hardware which
implements them.  Code does not use queued invalidation, see comments
for the reason, and does not provide interrupt remapping services.

Code implements the management of the guest address space per domain
and allows to establish and tear down arbitrary mappings, but not
partial unmapping.  The superpages are created as needed, but not
promoted.  Faults are recorded, fault records could be obtained
programmatically, and printed on the console.

Implement the busdma(9) using DMARs.  This busdma backend avoids
bouncing and provides security against misbehaving hardware and driver
bad programming, preventing leaks and corruption of the memory by wild
DMA accesses.

By default, the implementation is compiled into amd64 GENERIC kernel
but disabled; to enable, set hw.dmar.enable=1 loader tunable.  Code is
written to work on i386, but testing there was low priority, and
driver is not enabled in GENERIC.  Even with the DMAR turned on,
individual devices could be directed to use the bounce busdma with the
hw.busdma.pci<domain>:<bus>:<device>:<function>.bounce=1 tunable.  If
DMARs are capable of the pass-through translations, it is used,
otherwise, an identity-mapping page table is constructed.

The driver was tested on Xeon 5400/5500 chipset legacy machine,
Haswell desktop and E5 SandyBridge dual-socket boxes, with ahci(4),
ata(4), bce(4), ehci(4), mfi(4), uhci(4), xhci(4) devices.  It also
works with em(4) and igb(4), but there some fixes are needed for
drivers, which are not committed yet.  Intel GPUs do not work with
DMAR (yet).

Many thanks to John Baldwin, who explained me the newbus integration;
Peter Holm, who did all testing and helped me to discover and
understand several incredible bugs; and to Jim Harris for the access
to the EDS and BWG and for listening when I have to explain my
findings to somebody.

The mvs driver seems to be more functional than mv_sata and is not
causing random interrupt storms during boot.

61a3ac6e27 The MII layer shouldn't care about administrative status of an
interface. Make MII drivers forget about 'struct ifnet'.

Later plan is to provide an administrative downcall from ifnet
layer into drivers, to inform them about administrative status
change. If someone thinks that processing MII events for an
administratively down interface is a big problem, then drivers
would turn MII processing off.

The following MII drivers do evil things, like strcmp() on
driver name, so they still need knowledge of ifnet and thus
include if_var.h. They all need to be fixed:

sys/dev/mii/brgphy.c
sys/dev/mii/e1000phy.c
sys/dev/mii/ip1000phy.c
sys/dev/mii/jmphy.c
sys/dev/mii/nsphy.c
sys/dev/mii/rgephy.c
sys/dev/mii/truephy.c

dce533f390 Be a bit more flexible in how we find the console from the properties on
/chosen, following the list of allowed console properties in ePAPR. Also
do not require that stdin be defined and equal to stdout: stdin is
nonstandard (for ePAPR) and console in an unexpected place is after all
better than no console.

49e368ac48 Wait for DesignWare UART transfers completion before accessing line control
When using DW UART with BUSY detection it is necessary to wait
until all serial transfers are finished before manipulating the
line control. LCR will not be affected when UART is busy.
In addition, if Divisor Latch Access Bit is being set in order to
modify UART divisors:
1. We will get BUSY interrupt if interrupts are enabled.
2. Because LCR will not be affected the THR and (even worse) IER
   contents will be corrupted. This will lead to console hang.

8cf53c1244 Begin fleshing out a knob to enable/disable bluetooth coexistence.
Some firmware versions seem to get very unhappy if they're sent btcoex
commands when they don't actually have bluetooth hardware in them.
So, disable sending them those commands.

Tested:

* 5100 (which has bluetooth, no problems)
* 4965 (which doesn't have bluetooth, but didn't seem to crash)
* 6200 (no bluetooth, seems to get unhappy being sent bluetooth commands.)

2e6fe9b630 Temporarily disable multi-rate retry (link quality) and eliminate rate
index lookups.

* My recent(ish) change to iwn(4) and the net80211 rate control API to
  support 11n rates broke the link quality table use.  So, until I or
  someone else decides to fix it, let's just disable it for now.

* Teach iwn_tx_data_raw() to use the iwn_rate_to_plcp() function.

* Eliminate two uses of the net80211 rate index lookup functions - they
  are only for legacy rates and they're not needed here.

This fixes some invalid looking rate control TX issues that showed up
on my 4965 but it doesn't fix the two TX hangs I've noticed. Those look
like DMA related issues.

Tested:

* 4965, STA mode
* 5100, STA mode

498fa7c1f9 Add a helper routine to search for a compat string in a table that
associates compat strings with arbitrary values that mean something to
the driver.  This is handy for drivers that support several variations
of similar hardware and need to know which one matched.
