iwlwifi: pci: add a few more PCI subvendor IDs for the 7265 series

2015-11-09T22:37:31+00:00

commit f08f625876476b6c4a87834dc86e3b927f4697d2 upstream.

Add 3 new subdevice IDs for the 0x095A device ID and 2 for the 0x095B
device ID.

iwlwifi: mvm: flush fw_dump_wk when mvm fails to start

2015-11-09T22:37:30+00:00

commit dbf73d4a8bb8f4e1d1f3edd3be825692279e2ef3 upstream.

FW dump may be triggered when running init ucode, for example due to a
sysassert. In this case fw_dump_wk may run after mvm is freed, resulting
in a kernel panic.
Fix it by flushing the work.

iwlwifi: mvm: init card correctly on ctkill exit check

2015-11-09T22:37:30+00:00

commit 1a3fe0b2b6778b7866e2b3f5c9a299d5e9bbd89c upstream.

During the CT-kill exit flow, the card is powered up and partially
initialized to check if the temperature is already low enough.
Unfortunately the init bails early because the CT-kill flag is set.
Make the code bail early only for HW RF-kill, as was intended by the
author. CT-kill is self-imposed and is not really RF-kill.

iwlwifi: mvm: fix D3 firmware PN programming

2015-11-09T22:37:30+00:00

commit 2cf5eb3ab7bb7f2e3a70edcef236cd62c87db030 upstream.

The code to send the RX PN data (for each TID) to the firmware
has a devastating bug: it overwrites the data for TID 0 with
all the TID data, leaving the remaining TIDs zeroed. This will
allow replays to actually be accepted by the firmware, which
could allow waking up the system.

iwlwifi: mvm: fix D3 CCMP TX PN assignment

2015-11-09T22:37:30+00:00

commit 6645d5e441db9121793421d477255f4242b3dbf3 upstream.

When going into/coming out of D3, the TX PN must be programmed into
and restored from the firmware respectively. The restore was broken
due to my previous commit to move PN assignment into the driver.
Sending the PN to the firmware still worked since we now use the
counter that's shared with mac80211, but accessing it through the
mac80211 API makes no sense now.

Fix this by reading/writing the counter directly. This actually
simplifies the code since we don't need to round-trip through the
key_seq structure.

iwlwifi: mvm: clear csa countdown when AP is stopped

2015-11-09T22:37:30+00:00

commit e9cb0327b26dd7ba43a3b7a05b4b62219decf42d upstream.

The csa_countdown flag was not cleared when the AP is stopped.
As a result, if the AP was stopped after csa_countdown had started,
all the folowing channel switch commands would fail.
Fix that by clearing the csa_countdown flag when the AP is stopped.

rtlwifi: rtl8821ae: Fix system lockups on boot

2015-11-09T22:37:30+00:00

commit 54328e64047a54b8fc2362c2e1f0fa16c90f739f upstream.

In commit 1277fa2ab2f9 ("rtlwifi: Remove the clear interrupt routine from all
drivers"), the code that cleared all interrupt enable bits before setting them
was removed for all PCI drivers. This fixed an issue that caused TX to be
blocked for 3-5 seconds. On some RTL8821AE units, this change causes soft
lockups to occur on boot. For that reason, the portion of the earlier commit
that applied to rtl8821ae is reverted. Kernels 4.1 and newer are affected.

See http://marc.info/?l=linux-wireless&m=144373370103285&w=2 and
https://bugzilla.opensuse.org/show_bug.cgi?id=944978 for two cases where
this regression affected user systems. Note that this bug does not appear on
any of the developer's setups. For those users whose systems are affected
by the TX blockage, but do not lock up on boot, a module parameter is added
to disable the interrupt clear

iwlwifi: fix firmware filename for 3160

commit b5a48134f8af08f5243328f8a0b05fc5ae7cf343 upstream.

The MODULE_FIRMWARE() for 3160 should be using the 7260 version as
it's done in the device configuration struct instead of referencing
IWL3160_UCODE_API_OK which doesn't even exist.

ath9k: declare required extra tx headroom

2015-11-09T22:37:30+00:00

commit 029cd0370241641eb70235d205aa0b90c84dce44 upstream.

ath9k inserts padding between the 802.11 header and the data area (to
align it). Since it didn't declare this extra required headroom, this
led to some nasty issues like randomly dropped packets in some setups.
