Emmanuel Grumbach 984ecb9293 iwlagn: fix a race in the unmapping of the TFDs
While inspecting the code, I saw that iwl_tx_queue_unmap modifies
the read pointer of the Tx queue without taking any locks. This means
that it can race with the reclaim flow. This can possibly lead to
a DMA warning complaining that we unmap the same buffer twice.

This is more a W/A than a fix since it is really weird to take
sta_lock inside iwl_tx_queue_unmap, but it can help until we revamp
the locking model in the transport layer.

Johannes Berg d36120c625 iwlagn: stop interrupts when suspending
Occasionally, the device will send interrupts
while it is resuming, at a point where we are
not set up again to handle them. This causes
the core IRQ handling to completely disable
the IRQ, and then the driver won't work again
until it is reloaded/rebound.

To fix this issue disable the IRQ on suspend,
this will cause us to only get interrupts
again after we've setup everything on resume.

Updating the beacon every time right after one was
transmitted is pointless, most of the time we might
not even have to update it. We will update it every
time it changes, which includes from set_tim(), a
callback iwlwifi didn't implement so far.

This also reduces latency for clients, previously
we would update the beacon right after the previous
one was transmitted, and then a TIM change would
only take effect after that again -- updating the
beacon right after the TIM changes makes the TIM
change go out to the air faster.

Felix Fietkau 846d936350 ath9k_hw: fix a regression in key miss handling
The commit "ath9k_hw: Fix incorrect key_miss handling" changed the code
to only report key miss errors if a MIC error wasn't reported.
When checking the flags in that order in the MAC code, it might miss some
real events, because the value of the MIC error flag is undefined under
some conditions.

The primary issue addressed by the previous commit is making sure that
MIC errors are properly reported on the STA side. This can be fixed in
a better way by adding a separate rx status flag for key miss and
ignoring it for multicast frames.

This fix slightly improves stability in AP mode on some older hardware,
like AR9132.

th5k_hw_setup_tx_queue() returns a valid offset into the ah->ah_txq[]

Both have AR5K_NUM_TX_QUEUES elements.  So this error handling code

Also it's wrong.  The call to ath5k_hw_release_tx_queue() with a qnum

Thadeu Lima de Souza Cascardo c5d6136e10 mlx4_en: fix endianness with blue frame support
The doorbell register was being unconditionally swapped. In x86, that
meant it was being swapped to BE and written to the descriptor and to
memory, depending on the case of blue frame support or writing to
doorbell register. On PPC, this meant it was being swapped to LE and
then swapped back to BE while writing to the register. But in the blue
frame case, it was being written as LE to the descriptor.

The fix is not to swap doorbell unconditionally, write it to the
register as BE and convert it to BE when writing it to the descriptor.

Thomas Gleixner (tglx) reported that e1000 was delaying for many milliseconds

Mika Lansirinne 860502bf68 ixgbe: get pauseparam autoneg
There is a problem in the ixgbe driver with the reporting of the flow
control parameters. The autoneg parameter is shown to be of if
*either* it really is off, or current modes for both tx and rx are off.

The problem is seen when the parameters are read or set when the link
is down. In this case, the driver sees that tx and rx are currently off
and therefore autoneg parameter is incorrectly reported to be off too.
Also, the ethtool binary can not set the autoneg off since it sees that
it already is. When a link later comes up, the autonegotiation is
carried out normally and the driver later on reports the autoneg
parameter to be on (as it is) and then it can also be changed with
ethtool.

The patch is made against v3.0 kernel, but the problem seems to be there
since v2.6.30-rc1.

Reviewer comments: What we are trying to do is to disable flow control
while the cable is disconnected. Since ixgbe defaults to full flow
control, we call ethtool -A autoneg off rx off tx off while the cable
is disconnected. This doesn't work, because the driver sets
hw->fc.current_mode = ixgbe_fc_none if the cable is unplugged.
ixgbe_get_pauseparam() then reports to ethtool that nothing needs to be
done. The code fixes this, but it might have some unknown consequences.

Daniel Drake 8f641d93c3 libertas: detect TX lockups and reset hardware
Recent patches added support for resetting the SD8686 hardware when
commands time out, which seems to happen quite frequently soon after
resuming the system from a Wake-on-WLAN-triggered resume.

At http://dev.laptop.org/ticket/10969 we see the same thing happen
with transmits. In this case, the hardware will fail to respond to
a frame passed for transmission, and libertas (correctly) will block
all further commands and transmissions as the hardware can only
deal with one thing at a time. This results in a lockup while the
system waits indefinitely for the dead card to respond.

Hook up a TX lockup timer to detect this and reset the hardware.

The commit "mwifiex: remove list traversal.."(fcf2176c87..)
wrongly modifies AMSDU aggregation check. Due to this even though
packet size for iperf traffic is already large, we unnecessarily
try to aggregate them which adds some delay. If Tx iperf is started
on UUT for 30 seconds, UUT keeps sending Tx packets for few more
seconds.

That commit is reverted to fix the problem.
Also, MIN_NUM_AMSDU check is moved inside the loop to optimize the

If a VM is saved and restored (or migrated) the netback driver will no
longer process any Tx packets from the frontend.  xenvif_up() does not

just adds Tx requests to the ring without raising an event (until the
ring is full).

This was caused by 47103041e9 (net:

Andy Gospodarek a0db2dad09 bonding: properly stop queuing work when requested
During a test where a pair of bonding interfaces using ARP monitoring
were both brought up and torn down (with an rmmod) repeatedly, a panic
in the timer code was noticed.  I tracked this down and determined that
any of the bonding functions that ran as workqueue handlers and requeued
more work might not properly exit when the module was removed.

There was a flag protected by the bond lock called kill_timers that is
set when the interface goes down or the module is removed, but many of
the functions that monitor link status now unlock the bond lock to take
rtnl first.  There is a chance that another CPU running the rmmod could
get the lock and set kill_timers after the first check has passed.

This patch does not allow any function to queue work that will make
itself run unless kill_timers is not set.  I also noticed while doing
this work that bond_resend_igmp_join_requests did not have a check for
kill_timers, so I added the needed call there as well.

Add uAPSD support to mac80211. This is probably not
possible with all devices, so advertising it with
the cfg80211 flag will be left up to drivers that
want it.

Due to my previous patches it is now a fairly
straight-forward extension. Drivers need to have
accurate TX status reporting for the EOSP frame.
For drivers that buffer themselves, the provided
APIs allow releasing the right number of frames,
but then drivers need to set EOSP and more-data
themselves. This is documented in more detail in
the new code itself.

Johannes Berg 042ec45337 mac80211: let drivers inform it about per TID buffered frames
For uAPSD implementation, it is necessary to know on
which ACs frames are buffered. mac80211 obviously
knows about the frames it has buffered itself, but
with aggregation many drivers buffer frames. Thus,
mac80211 needs to be informed about this.

For now, since we don't have APSD in any form, this
will unconditionally set the TIM bit for the station
but later with uAPSD only some ACs might cause the
TIM bit to be set.

ath9k is the only driver using this API and I only
modify it in the most basic way, it won't be able
to implement uAPSD with this yet. But it can't do
that anyway since there's no way to selectively
release frames to the peer yet.

Since drivers will buffer frames per TID, let them
inform mac80211 on a per TID basis, mac80211 will
then sort out the AC mapping itself.

Rasesh Mody 5bcf6ac036 bna: Add Callback to Fix RXQ Stop
Change details:
 - Add a callback in the BNA, which is called before sending FW command to stop
   RxQs. After this callback is called, driver should not post anymore Rx
   buffers to the RxQ. This addresses a small window where driver posts Rx
   buffers while FW is stopping/has stopped the RxQ.
 - Registering callback function, rx_stall_cbfn, during bna_rx_create.
   Invoking callback function, rx_stall_cbfn, before sending rx_cfg_clr
   command to FW
 - Bnad_cb_rx_stall implementation - set a flag in the Rxq to mark buffer
   posting disabled state. While posting buffers check for the above flag.

Revise high and low threshold marks wrt flow control to account
for the X540 devices and latency introduced by the loopback
switch.

Without this it was in theory possible to drop frames on a
supposedly lossless link with X540 or SR-IOV enabled.

Previously we used a magic number in a define to calculate the
threshold values. This made it difficult to sort out exactly
which latencies were or were not being accounted for. Here
I was overly explicit and tried to used #define names that would
be recognizable after reading the IEEE 802.1Qbb specification.

This patch is meant to help cleanup the interrupt throttle rate logic by
storing the interrupt throttle rate as a value in microseconds instead of
interrupts per second.  The advantage to this approach is that the value
can now be stored in an 16 bit field and doesn't require as much math to
flip the value back and forth since the hardware already used microseconds
when setting the rate.

Dean Nelson d5bc77a223 e1000: don't enable dma receives until after dma address has been setup
Doing an 'ifconfig ethN down' followed by an 'ifconfig ethN up' on a qemu-kvm
guest system configured with two e1000 NICs can result in an 'unable to handle
kernel paging request at 0000000100000000' or 'bad page map in process ...' or
something similar.

These result from a 4096-byte page being corrupted with the following two-word
pattern (16-bytes) repeated throughout the entire page:

  0x0000000000000000
  0x0000000100000000

There can be other bits set as well. What is a constant is that the 2nd word
has the 32nd bit set. So one could see:

        :
  0x0000000000000000
  0x0000000100000000
  0x0000000000000000
  0x0000000172adc067    <<< bad pte
  0x800000006ec60067
  0x0000000700000040
  0x0000000000000000
  0x0000000100000000
        :

Which came from from a process' page table I dumped out when the marked line
was seen as bad by print_bad_pte().

The repeating pattern represents the e1000's two-word receive descriptor:

struct e1000_rx_desc {
        __le64 buffer_addr;   /* Address of the descriptor's data buffer */
        __le16 length;        /* Length of data DMAed into data buffer */
        __le16 csum;          /* Packet checksum */
        u8 status;            /* Descriptor status */
        u8 errors;            /* Descriptor Errors */
        __le16 special;
};

And the 32nd bit of the 2nd word maps to the 'u8 status' member, and
corresponds to E1000_RXD_STAT_DD which indicates the descriptor is done.

The corruption appears to result from the following...

 . An 'ifconfig ethN down' gets us into e1000_close(), which through a number
   of subfunctions results in:
     1. E1000_RCTL_EN being cleared in RCTL register.  [e1000_down()]
     2. dma_free_coherent() being called.  [e1000_free_rx_resources()]

 . An 'ifconfig ethN up' gets us into e1000_open(), which through a number of
   subfunctions results in:
     1. dma_alloc_coherent() being called.  [e1000_setup_rx_resources()]
     2. E1000_RCTL_EN being set in RCTL register.  [e1000_setup_rctl()]
     3. E1000_RCTL_EN being cleared in RCTL register.  [e1000_configure_rx()]
     4. RDLEN, RDBAH and RDBAL registers being set to reflect the dma page
        allocated in step 1.  [e1000_configure_rx()]
     5. E1000_RCTL_EN being set in RCTL register.  [e1000_configure_rx()]

During the 'ifconfig ethN up' there is a window opened, starting in step 2
where the receives are enabled up until they are disabled in step 3, in which
the address of the receive descriptor dma page known by the NIC is still the
previous one which was freed during the 'ifconfig ethN down'. If this memory
has been reallocated for some other use and the NIC feels so inclined, it will
write to that former dma page with predictably unpleasant results.

I realize that in the guest, we're dealing with an e1000 NIC that is software
emulated by qemu-kvm. The problem doesn't appear to occur on bare-metal. Andy
suspects that this is because in the emulator link-up is essentially instant
and traffic can start flowing immediately. Whereas on bare-metal, link-up
usually seems to take at least a few milliseconds. And this might be enough
to prevent traffic from flowing into the device inside the window where
E1000_RCTL_EN is set.

So perhaps a modification needs to be made to the qemu-kvm e1000 NIC emulator
to delay the link-up. But in defense of the emulator, it seems like a bad idea
to enable dma operations before the address of the memory to be involved has
been made known.

The following patch no longer enables receives in e1000_setup_rctl() but leaves
them however they were. It only enables receives in e1000_configure_rx(), and
only after the dma address has been made known to the hardware.

There are two places where e1000_setup_rctl() gets called. The one in
e1000_configure() is followed immediately by a call to e1000_configure_rx(), so
there's really no change functionally (except for the removal of the problem
window. The other is in __e1000_shutdown() and is not followed by a call to
e1000_configure_rx(), so there is a change functionally. But consider...

 . An 'ifconfig ethN down' (just as described above).

 . A 'suspend' of the system, which (I'm assuming) will find its way into
   e1000_suspend() which calls __e1000_shutdown() resulting in:
     1. E1000_RCTL_EN being set in RCTL register.  [e1000_setup_rctl()]

And again we've re-opened the problem window for some unknown amount of time.

This patch adds support for SJW user settings to not set the synchronization
jump width (SJW) to 1 in any case when using the in-kernel bittiming
calculation.

The ip-tool from iproute2 already supports to pass the user defined SJW
value. The given SJW value is sanitized with the controller specific sjw_max
and the calculated tseg2 value. As the SJW can have values up to 4 providing
this value will lead to the maximum possible SJW automatically. A higher SJW
allows higher controller oscillator tolerances.

Dan Carpenter 2fb40577b0 wl3501_cs: min_t() cast truncates high bits
wrqu->encoding.length comes from the network administrator.  It's
size u16.  We want to limit "tocopy" to the smallest value of either
"len_keys", "wrqu->encoding.length" or 100.  But because .length
gets cast from u16 to u8 we might use a random, smaller value than
the was desired.  It's probably not very serious, but we may as well
fix it.

Johannes Berg 84b1bec6d7 iwlagn: fix scan complete processing
When we cancel a scan, the completion runs
only from the workqueue. This can cause the
remain-on-channel scan to fail when another
one was just canceled, because we're still
aborting it.

To fix this, run the completion inline with
the lock still held before returning from
iwl_scan_cancel_timeout().

Also, to avoid the scan complete work from
completing a new scan prematurely, add a
new STATUS_SCAN_COMPLETE bit.

Johannes Berg 8bd2c1ead5 iwlagn: fix dangling scan request
If iwl_scan_initiate() fails for any reason,
priv->scan_request and priv->scan_vif are left
dangling. This can lead to a crash later when
iwl_bg_scan_completed() tries to run a pending
scan request.

In practice, this seems to be very rare due to
the STATUS_SCANNING check earlier. That check,
however, is wrong -- it should allow a scan to
be queued when a reset/roc scan is going on.
When a normal scan is already going on, a new
one can't be issued by mac80211, so that code
can be removed completely. I introduced this
bug when adding off-channel support in commit
266af4c745.

Since all the queue logic has been moved to the transport layer,
the sequence number is set in the transport layer.
While doing that I forgot that the mac header is copied to the
TB of the TX cmd in the upper layer before the call to the transport
layer. So basically we used the sequence number from mac80211...
This was fine for the first assocation but after the second, mac80211
resets its counters while we don't hence a shift that led to terrible
impact on performance.

Amitkumar Karwar 5116f3cef2 mwifiex: update bss band information
In recent commit "mwifiex: use cfg80211 dynamic scan..."
(7c6fa2a843..) scan table handling in driver is removed to
make use of cfg80211 dynamic scan table. Now driver sends
beacon buffers found in scanning directly to stack and parse
the buffer for requested BSS only during association.

Beacon buffer doesn't contain bss band information. Driver
gets it from firmware in separate tlv (chan_band_tlv).
Currently since we don't inform stack about bss bandinfo,
there is an issue with 5GHz association.

Use "priv" field of struct cfg80211_bss to store bandinfo.
This fixes 5GHz association issue.

Sometimes association in 5GHz doesn't work. Dmesg log shows
"Can not find requested SSID xyz" error message. Currently
while preparing scan channel list for firmware Null entries
are created for disabled channels. The routine which retrieves
this list ignores channels after Null entry. Hence sometimes
driver doesn't scan the channel of requested AP and association
fails. The issue is fixed by avoiding those NULL entries.

Daniel Drake b4c3f34aff libertas: scan behaviour consistency improvements
When scanning for the broadcast SSID, there is no need to add the
SSID TLV (restoring the behaviour of the driver behaviour in the wext
days, confirmed in Marvell specifications).

If bssid is unspecified, the current scan code will usually fire off an
active scan probing for the specific requested SSID. However, if a scan
is ongoing (or has just finished), those scan results will be used
instead (even if that scan is totally different, e.g. a passive scan on
channel 4 for a different SSID). Fix this inconsistency by always
firing off a scan when associating without a bssid.
