2016-09-19iwlwifi: mvm: support BAR in reorder bufferSara Sharon1-3/+9
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.

2016-09-19iwlwifi: mvm: fix DQA AP mode station assumptionSara Sharon1-7/+28
There was recently a Full AP mode feature added where hostap adds the station at auth stage, and not assoc. However, when running with legacy hostapd, we get the auth response before station was added, and tx_skb_non_sta fails to allocate a queue, resulting in a complete failure of association. Take care of this situation as well. Add a warning when no valid queue is returned at all and make mvm drop the packet instead of passing it on. Refactor the function a bit while at it.

2016-09-19iwlwifi: check for valid ethernet address provided by OEMHaim Dreyfuss1-5/+10
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.

2016-09-17mwifiex: fix null pointer deference when adapter is nullColin Ian King1-4/+4
If adapter is null the error exit path in mwifiex_shutdown_sw is to down the semaphore sem and print some debug via mwifiex_dbg. However, passing a NULL adapter to mwifiex_dbg causes a null pointer deference when accessing adapter->dev. This fix checks for a null adapter at the start of the function and to exit without the need to up the semaphore and we also skip the debug to avoid the null pointer dereference.

2016-09-17mwifiex: fix error handling in mwifiex_create_custom_regdomainBob Copeland1-5/+8
smatch reports: sta_cmdresp.c:1053 mwifiex_create_custom_regdomain() warn: possible memory leak of 'regd' Indeed, mwifiex_create_custom_regdomain() returns NULL in the case that channel is missing in the TLV without freeing regd. Moreover, some other error paths in this function return ERR_PTR values which are assigned without checking to the regd field in the mwifiex_adapter struct. The latter is only null-checked where used. Fix by freeing regd in the error path, and only update priv->adapter->regd if the returned pointer is valid.

2016-09-16iwlwifi: mvm: make RSS RX more robustJohannes Berg1-1/+1
If the firmware ever decides to send any new/more notifications to the RSS queues, the driver would currently try to interpret those as REPLY_RX_MPDU_CMD and, if the notification was small, access invalid memory. Prevent that by checking for REPLY_RX_MPDU_CMD explicitly which allows ignoring unexpected notifications.

2016-09-16iwlwifi: pcie: Set affinity mask for rx interrupt vectors per cpuHaim Dreyfuss2-1/+33
In order to utilize the host's CPUs in the most efficient way we bind each rx interrupt vector to each CPU on the host. Each rx interrupt is prioritized to execute only on the designated CPU rather than any CPU. Processor affinity takes advantage of the fact that some remnants of a process that was run on a given processor may remain in that processor's memory state for example, data in the CPU cache after another process is run on that CPU. Scheduling that process to execute on the same processor could result in an efficient use of process by reducing performance-degrading situations such as cache misses and parallel processing.

2016-09-16iwlwifi: mvm: free reserved queue on STA removalLiad Kaufman1-1/+23
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.

2016-09-16iwlwifi: mvm: fix pending frames tracking on tx respLiad Kaufman1-1/+5
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.

2016-09-16iwlwifi: pcie: Configure shared interrupt vector in MSIX modeHaim Dreyfuss4-55/+132
In case the OS provides fewer interrupts than requested, different causes will share the same interrupt vector as follow: 1.One interrupt less: non rx causes shared with FBQ. 2.Two interrupts less: non rx causes shared with FBQ and RSS. 3.More than two interrupts: we will use fewer RSS queues.

2016-09-15iwlwifi: mvm: call a different txq_enable functionSara Sharon1-3/+1
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.

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.
