ath9k_htc: fix random decryption failure

2014-10-05T20:41:08+00:00

commit d21ccfd0a60ea3dece3e1d142f52694abf87a0b1 upstream.

In v3.15 the driver stopped to accept network packets after successful
authentification, which could be worked around by passing the
nohwcrypt=1 module parameter.  This was not reproducible by
everyone, and showed random behaviour in some tests.
It was caused by an uninitialized variable introduced
in 4ed1a8d4a257 ("ath9k_htc: use ath9k_cmn_rx_accept") and
used in 341b29b9cd2f ("ath9k_htc: use ath9k_cmn_rx_skb_postprocess").

brcmfmac: handle IF event for P2P_DEVICE interface

2014-10-05T20:41:07+00:00

commit 87c4790330810fe5caf0172d9320cf24ef19cebe upstream.

The firmware notifies about interface changes through the IF event
which has a NO_IF flag that means host can ignore the event. This
behaviour was introduced in the driver by:

  commit 2ee8382fc6c763c76396a6aaff77a27089eed3aa
  Author: Arend van Spriel 
  Date:   Sat Aug 10 12:27:24 2013 +0200

      brcmfmac: ignore IF event if firmware indicates it

It turns out that the IF event for the P2P_DEVICE also has this
flag set, but the event should not be ignored in this scenario.
The mentioned commit caused a regression in 3.12 kernel in creation
of the P2P_DEVICE interface.

iwlwifi: mvm: set MAC_FILTER_IN_BEACON correctly for STA/P2P client

2014-10-05T20:41:05+00:00

commit 7c8b3bc688bdcfd7789efbd17da4d85b104ad351 upstream.

In commit cad3f08c (iwlwifi: mvm: enable MAC_FILTER_IN_BEACON when
forced_assoc_off is set) the code to set the MAC_FILTER_IN_BEACON flag
was accidentally moved to the main block of the if statement, while it
should be in the else block instead.  Move it to the right place.

iwlwifi: mvm: treat EAPOLs like mgmt frames wrt rate

2014-10-05T20:41:05+00:00

commit aa11bbf3df026d6b1c6b528bef634fd9de7c2619 upstream.

Using the LQ table which is initially set according to
the rssi could lead to EAPOLs being sent in high legacy
rates like 54mbps.
It's better to avoid sending EAPOLs in high rates as it reduces
the chances of a successful 4-Way handshake.
Avoid this and treat them like other mgmt frames which would
initially get sent at the basic rate.

iwlwifi: mvm: fix endianity issues with Smart Fifo commands

commit 86974bff066dd8b98be46d7c7d3aba89034f0833 upstream.

This code was broken on big endian systems. Sparse didn't
catch the bug since the firmware command was not tagged as
little endian.
Fix the bug for big endian systems and tag the field in the
firmware command to prevent such issues in the future.

commit cbd5228199d8be45d895d9d0cc2b8ce53835fc21 upstream.

Hidden away in the last 8 bytes of the buffer_list page is a solitary
statistic. It needs to be byte swapped or else ethtool -S will
produce numbers that terrify the user.

Since we do this in multiple places, create a helper function with a
comment explaining what is going on.

carl9170: fix sending URBs with wrong type when using full-speed

2014-10-05T20:40:50+00:00

commit 671796dd96b6cd85b75fba9d3007bcf7e5f7c309 upstream.

The driver assumes that endpoint 4 is always an interrupt endpoint.
Unfortunately the type differs between high-speed and full-speed
configurations while in the former case it is indeed an interrupt
endpoint this is not true for the latter case - here it is a bulk
endpoint. When sending URBs with the wrong type the kernel will
generate a warning message including backtrace. In this specific
case there will be a huge amount of warnings which can bring the system
to freeze.

To fix this we are now sending URBs to endpoint 4 using the type
found in the endpoint descriptor.

A side note: The carl9170 firmware currently specifies endpoint 4 as
interrupt endpoint even in the full-speed configuration but this has
no relevance because before this firmware is loaded the endpoint type
is as described above and after the firmware is running the stick is not
reenumerated and so the old descriptor is used.
