iwlwifi: mvm: bail out if CTDP start operation fails

2016-10-31T11:02:14+00:00

commit 75cfe338b8a6fadaa28879a969047554701a7589 upstream.

We were assigning the return value of iwl_mvm_ctdp_command() to a
variable, but never checking it.  If this command fails, we should not
allow the interface up process to proceed, since it is potentially
dangerous to ignore thermal management requirements.

iwlwifi: mvm: disable P2P queue on mac context release

commit 341d7eb8223bdd48bdf75729487a2de5e01623b3 upstream.

AP queue is properly released, but P2P queue isn't.

iwlwifi: mvm: support BAR in reorder buffer

2016-10-31T11:02:14+00:00

commit 9a73a7d24d51eaf9e43c771c53cf7b594e5b5334 upstream.

On default queue we will not receive frame release notification,
but the BAR itself.
Upon receiving the BAR driver should look at the NSSN and adjust
window accordingly.

iwlwifi: mvm: free reserved queue on STA removal

2016-10-31T11:02:14+00:00

commit a0315dea9091d1ebc1534f6129b3fc9942b8ca99 upstream.

When a STA is removed in DQA mode, if no traffic went through
its reserved queue, the txq continues to be marked as
reserved and no STA can use it.

Make sure that in such a case the reserved queue is marked
as free when the STA is removed.

iwlwifi: mvm: call a different txq_enable function

2016-10-31T11:02:13+00:00

commit ca3b9c6b6d4db9a8ba5fc8b95664e75468c59f9f upstream.

Since the SCD_QUEUE_CFG command was introduced the driver
calls iwl_trans_txq_enable_cfg() with a NULL for scd_cfg
parameter.
This makes the transport avoid writing to the SCD pointers,
since it can cause races with firmware, which is also accessing
the registers.
The transport only updates the write pointer in that case.
Fix a wrong call to iwl_trans_txq_enable() which caused a
scd_cfg parameter to be sent to transport, resulting with an
access to SCD registers.

iwlwifi: mvm: fix pending frames tracking on tx resp

2016-10-31T11:02:13+00:00

commit 7585c354637bb003ce612dd22f5047c015545ef4 upstream.

In iwl_mvm_rx_tx_cmd_single(), when checking if a given TID is
aggregated, the driver doesn't check whether or not the queue
itself can be aggregated. For example, a management queue might
be marked as aggregated if TID 0 is aggregated on a (different)
data queue.

Make sure that mgmt frames are sent with TID IWL_TID_NON_QOS,
and in this way make sure no mixups of this sort happen.

iwlwifi: check for valid ethernet address provided by OEM

2016-10-31T11:02:13+00:00

commit a6c934b364948cd4de5bd9ab055bb65206ec70f3 upstream.

In 9000 family products we added an option to let the OEM fuse the
mac address via registers. If these registers are zeroed we use the OTP
address instead. Make sure that the address provided by the OEM is valid
and, if not, fall back to the OTP address as well.

iwlwifi: mvm: update TX queue before making a copy of the skb

2016-09-15T15:35:20+00:00

Off-channel action frames (such as ANQP frames) must be sent either on
the AUX queue or on the offchannel queue, otherwise the firmware will
cause a SYSASSERT.

In the current implementation, the queue to be used is correctly set in
the original skb, but this is done after it is copied.  Thus the copy
remains with the original, incorrect queue.

Fix this by setting the queue in the original skb before copying it.
