2012-03-05wl12xx: configure the correct beacon_intervalEliad Peller1-0/+1
We didn't update the beacon interval on association (or on a change notification when working as sta), so the default interval (100ms) was always used. Update the beacon interval according to the bss_conf before starting the sta role (on association). Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: don't allow scanning while device is in ROCEliad Peller1-4/+2
return EBUSY on scan when there is any role in ROC (not necessarily the one we are going to use) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: don't handle change_channel while associatedEliad Peller1-27/+14
Currently, CHANGE_CHANNEL indication while associated is considered as roaming attempt. However, with the new auth/assoc redesign, we no longer have to handle this case, so remove it. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: set correct vif type in change_interface callbackEliad Peller1-1/+1
In some cases, the wrong vif type was set in the change_interface callback (P2P_CLIENT/P2P_GO instead of STA/AP) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: increment session_counter for device role as wellEliad Peller1-1/+1
The sesssion_counter has to be incremented each time the dev is started (similar to sta role). Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: set authorized AP on sta_state notificationEliad Peller2-97/+23
wl12xx currently looks for AP authorization by registering a netdev notifier and waiting for the IF_OPER_UP notification, which is quite cumbersome. Use the newly introduced sta_state callback (waiting for assoc -> auth notification) instead, in order to simplify it.

2012-03-05wl12xx: implement sta_state callbackEliad Peller1-55/+82
Implement sta_state callback instead of the sta_add/remove callbacks. Update the fw regarding peer state and ht caps only after the station was authorized. Otherwise, the fw might try establishing BA session before the sta is authorized. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: consider bss_conf->idle instead of hw->conf.flagsEliad Peller1-2/+1
On disassociation, check only whether the current vif is idle, instead of checking whether the device is idle. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: don't start dev role on ibss vifsEliad Peller1-4/+2
device role is used for scanning and sending packets before connection. however, since we don't need to send packets before ibss creation, there is no need to start the device on idle-off. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-28wl12xx: increase dynamic PS timeout to 200msArik Nemtsov1-1/+1

2012-02-28wl12xx: flush Tx during suspend and 802.11h chan switchArik Nemtsov1-0/+4
Flush our Tx queues before suspending or changing the channel due to a channel_switch element in the AP beacon. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-28wl12xx: flush all Tx queues on tx_flush timeoutArik Nemtsov1-0/+7
Ensure our queues are empty at the end of a tx_flush(), in case we timeout on passively waiting for them. This makes sure no left-overs are transmitted when we are on the wrong channel. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-28wl12xx: avoid starving the system hlidArik Nemtsov1-4/+13
Re-factor the Tx scheduler so that the system_hlid is taken into account before restarting an iteration over the wlvifs. Previously this hlid had a lower priority and would starve if some wlvif had many packets. In addition avoid iterating over wlvifs past last_wlvif when performing the a second pass. If we had packets in those wlvifs they would have been found earlier. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-28wl12xx: reset link Tx queues when freeing itArik Nemtsov3-4/+17
Before, the link was first freed (invalidating it in the map), and later on vif removal, all valid wlvif-related links were reset. Since these links were already invalid, we failed to reset them. The bug was made worse by op_stop, which set the tx_queue_count to 0 arbitrarily. This resulted in a negative tx_queue_count in some scenarios. Fix this by resetting the Tx-queues of a link when freeing it. Add a WARN_ON and reset all link Tx-queues in op_stop, to avoid a negative tx_queue_count. [changed WARN_ON to WARN_ON_ONCE -- Luca] Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-28wl12xx: change bits in the link_map under spin lockArik Nemtsov1-0/+9
These bits are used in op_tx to determine if a packet should be dropped. As such we should use the spin lock to sync the state. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-28wl12xx: set the ELP entry delay to the FW dyn-ps timeoutArik Nemtsov1-3/+1
With PSM handled in FW, the checks in wl1271_elp_work() are always true. Thus during active traffic we constantly enter and exit ELP (many times per second). As each ELP exit takes ~10ms, this can have an adverse effect on throughput and interactivity. Set the ELP timeout to the dyn-ps timeout. This period is longer and avoids the above problem. It also makes sense to stay out of ELP while we are awake on the network, to minimize delays in Tx/Rx. The same thing was done by the mac80211 dynamic-ps mechanism before the FW DPS changes.

2012-02-27mac80211: fix sta_info_flush() return valueJohannes Berg1-1/+3
The comment for sta_info_flush() states "Returns the number of removed STA entries" but that isn't actually true. Consequently, the warning when a station is still around on interface removal can never trigger and this delayed finding the timer issue the previous patch fixed. Fix the return value here to make that warning useful again. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-02-27mac80211: fix auth/assoc data & timer leakJohannes Berg3-0/+16
When removing an interface while it is in the process of authenticating or associating, we leak the auth_data or assoc_data, and leave the timer pending. The timer then crashes the system when it fires as its data is gone. Fix this by explicitly deleting all the data when the interface is removed. This uncovered another bug -- this problem should have been detected by the sta_info_flush() warning but that function doesn't ever return non-zero, I'll fix that in a separate patch.
