2013-08-11iwlwifi: mvm: refuse connection to APs with BI < 16Johannes Berg
commit 48bc13072109ea58465542aa1ee31b4e1065468a upstream. Due to a firmware bug, it crashes when the beacon interval is smaller than 16. Avoid this by refusing the station state change creating the AP station, causing mac80211 to abandon the attempt to connect to the AP, and eventually wpa_s to blacklist it.

2013-05-16iwlwifi: mvm: fix aggregation drain flowEmmanuel Grumbach
Move the counter for non-AMPDU frames to mvm. It is needed for the drain flow which happens once the ieee80211_sta has been freed, so keeping it in iwl_mvm_sta which is embed into ieee80211_sta is not a good idea. Also, since its purpose it to remove the STA in the fw only after all the frames for this station have exited the shared Tx queues, we need to decrement it in the reclaim flow. This flow can happen after ieee80211_sta has been removed, which means that we have no iwl_mvm_sta there. So we can't know what is the vif type. Hence, we know audit these frames for all the vif types. In order to avoid spawning sta_drained_wk all the time, we now check that we are in a flow in which draining might happen - only when mvmsta is NULL. This is better than previous code that would spawn sta_drained_wk all the time in AP mode.

2013-04-03iwlwifi: mvm: clean up invalid station handlingEmmanuel Grumbach
Using IWL_MVM_STATION_COUNT and IWL_INVALID_STATION together isn't a good idea as they have different values. Always use IWL_MVM_STATION_COUNT for an invalid station in MVM and move the definition of the IWL_INVALID_STATION constant into the DVM driver to avoid making such mistakes again. The one use in the transport code can be hard-coded to -1 instead as the station ID is passed as an integer there.

2013-04-03iwlwifi: mvm: don't disable power management due to P2P deviceAlexander Bondar
Currently power management is supported only when only a single virtual interface is present. The driver verifies number of created interfaces and disables power management when multiple interfaces present. However, this rule does not extend to a P2P device that is handled differently in the firmware. If a P2P device is added power management can remain enabled.

Increase the maximal remain on channel time as longer remain on channel requests are handled by the FW using fragmented time events. This reduces the number of user/kernel space iterations during flows such as p2p_listen. In addition it is currently required for flows which require longer duration such as p2p_sd.

2013-03-06iwlwifi: mvm: implement remote wakeJohannes Berg
With remote wake, the firmware creates a TCP connection and sends some configurable data on it, until a special TCP data packet from the server is received that triggers a wakeup. The configuration is a bit tricky because it is based on packet pattern matching but this is hidden in the driver and the exposed API in cfg80211 is just based on the required TCP connection parameters.

2013-03-06iwlwifi: mvm: support IEEE80211_AMPDU_TX_STOP_FLUSHEmmanuel Grumbach
mac80211 tells us when we need to dump the frames from the AGG queue instead of releasing them as single MPDUs. Being able to differentiate between the different cases (IEEE80211_AMPDU_TX_STOP_*) allows us to handle races better. When the station is removed, mac80211 asks to flush and removes the station right away. This allows to avoid a case where we still have frames in AGG queues, but the station has been remove already. Note that we can have frames on the shared queues, but this is not a problem: the station in the fw will be kept until all the frames on the shared queues have been drained. AGG queues are a special case since they are dynamically allocated. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-02-26iwlwifi: mvm: fix AP/GO mode station removalJohannes Berg
When stations are removed while packets are in the queue, we drain the queues first, and then remove the stations. If this happens in AP mode while the interface is removed the MAC context might be removed from the firmware before we removed the station(s), resulting in a SYSASSERT 3421. This is because we remove the MAC context from the FW in stop_ap(), but only flush the station drain work later in remove_interface(). Refactor the code a bit to have a common MAC context removal preparation first to solve this.

In managed mode, the HT/VHT capabilities aren't set when the station is initially added, so update the station when it is marked associated. In AP/GO mode, the station will typically be added with full capabilities today, but an upcoming change in hostapd may mean a similar scenario as for managed mode, therefore do the update unconditionally.

2013-02-12iwlwifi: mvm: don't delay the association until after beaconJohannes Berg
If we haven't heard a beacon before we associate we can still start the association process and set the MAC in the firmware to associated only after having received a beacon with DTIM period by reacting to the new change flag (BSS_CHANGED_DTIM_PERIOD) from mac80211.
