2010-02-08mac80211: fix deauth raceJohannes Berg
When userspace requests a deauth while the authentication work is pending in the auth (not probe) state, we do not properly abort the work and then things get confused. Fix that and also improve the checks here to include the correct virtual interface, just in case two virtual interfaces would ever try to connect to the same BSS. Also fix a bug -- need to use list_del_rcu instead of just list_del to free a work item. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2010-02-08iwlwifi: Send broadcast probe request only when asked toSamuel Ortiz
When running directed active scans we currently end up sending both the SSID probe requests and an additional broadcast one. This is due to the fact that we always leave the probe request template SSID IE length to 0. Instead we should set it to the first SSID to scan, and fill the direct_scan array with the remaining SSIDs to scan for. This way we only send what we've been asked to: a broadcast probe request when no directed scan is requested, and directed probe requests otherwise.

2010-02-08iwlwifi: Add chain_noise support for 6050Ben Cahill
Existing iwl6050_ops->iwl6050_hcmd_utils structure had no pointers to chain noise functions (gain_computation and chain_noise_reset). As it turns out, by adding chain_noise_scale (see related patch), there is no need for separate chain noise function, so simply use iwl6000_ops->iwl5000_hcmd_utils, and remove those for 6050.

2010-02-08mac80211: tear down all agg queues when restart/reconfig hwWey-Yi Guy
When there is a need to restart/reconfig hw, tear down all the aggregation queues and let the mac80211 and driver get in-sync to have the opportunity to re-establish the aggregation queues again. Need to wait until driver re-establish all the station information before tear down the aggregation queues, driver(at least iwlwifi driver) will reject the stop aggregation queue request if station is not ready. But also need to make sure the aggregation queues are tear down before waking up the queues, so mac80211 will not sending frames with aggregation bit set.

2010-02-08mac80211: allow station add/remove to sleepJohannes Berg
Many drivers would like to sleep during station addition and removal, and currently have a high complexity there from not being able to. This introduces two new callbacks sta_add() and sta_remove() that drivers can implement instead of using sta_notify() and that can sleep, and the new sta_add() callback is also allowed to fail. The reason we didn't do this previously is that the IBSS code wants to insert stations from the RX path, which is a tasklet, so cannot sleep. This patch will keep the station allocation in that path, but moves adding the station to the driver out of line. Since the addition can now fail, we can have IBSS peer structs the driver rejected -- in that case we still talk to the station but never tell the driver about it in the control.sta pointer. If there will ever be a driver that has a low limit on the number of stations and that cannot talk to any stations that are not known to it, we need to do come up with a new strategy of handling larger IBSSs, maybe quicker expiry or rejecting peers.

For debugging hardware scan trigger/complete functionality, it was useful to have code in hwsim that pretends to do a hardware scan.

2010-02-08mac80211: fix deferred hardware scan requestsJohannes Berg
Reinette found the reason for the warnings that happened occasionally when a hw-offloaded scan finished; her description of the problem: mac80211 will defer the handling of scan requests if it is busy with management work at the time. The scan requests are deferred and run after the work has completed. When this occurs there are currently two problems. * The scan request for hardware scan is not fully populated with the band and channels to scan not initialized. * When the scan is queued the state is not correctly updated to reflect that a scan is in progress. The problem here is that when the driver completes the scan and calls ieee80211_scan_completed() a warning will be triggered since mac80211 was not aware that a scan was in progress. The reason is that the queued scan work will start the hw scan right away when the hw_scan_req struct has already been allocated. However, in the first pass it will not have been filled, which happens at the same time as setting the bits. To fix this, simply move the allocation after the pending work test as well, so that the first iteration of the scan work will call __ieee80211_start_scan() even in the hardware scan case.

2010-02-03b43: Fix throughput regressionLarry Finger
Commit c7ab5ef9bcd281135c21b4732c9be779585181be entitled "b43: implement short slot and basic rate handling" reduced the transmit throughput for my BCM4311 device from 18 Mb/s to 0.7 Mb/s. The basic rate handling portion is OK, the problem is in the short slot handling. Prior to this change, the short slot enable/disable routines were never called. Experimentation showed that the critical part was changing the value at offset 0x0010 in the shared memory. This is supposed to contain the 802.11 Slot Time in usec, but if it is changed from its initial value of zero, performance is destroyed. On the other hand, changing the value in the MMIO register corresponding to the Interframe Slot Time increased performance from 18 to 22 Mb/s. A BCM4306/3 also shows dramatic improvement of the transmit rate from 5.3 to 19.0 Mb/s. Other changes in the patch include removal of the magic number for the MMIO register, and allowing the slot time to be set for any PHY operating in the 2.4 GHz band. Previously, the routine was executed only for G PHYs.

2010-02-01mac80211: fix sta lookup with AP VLAN interfaces and injected framesFelix Fietkau
When injecting frames, mac80211 currently looks for the first AP interface that matches the source address of the injected frame.
