2011-07-08mac80211: fix TKIP races, make API easier to useJohannes Berg3-6/+3
Our current TKIP code races against itself on TX since we can process multiple packets at the same time on different ACs, but they all share the TX context for TKIP. This can lead to bad IVs etc. Also, the crypto offload helper code just obtains the P1K/P2K from the cache, and can update it as well, but there's no guarantee that packets are really processed in order. To fix these issues, first introduce a spinlock that will protect the IV16/IV32 values in the TX context. This first step makes sure that we don't assign the same IV multiple times or get confused in other ways. Secondly, change the way the P1K cache works. I add a field "p1k_iv32" that stores the value of the IV32 when the P1K was last recomputed, and if different from the last time, then a new P1K is recomputed. This can cause the P1K computation to flip back and forth if packets are processed out of order. All this also happens under the new spinlock. Finally, because there are argument differences, split up the ieee80211_get_tkip_key() API into ieee80211_get_tkip_p1k() and ieee80211_get_tkip_p2k() and give them the correct arguments.

2011-07-08wl12xx: start/stop queues according to global per-AC countersArik Nemtsov6-24/+51
Split tx_queue_count to count per-AC skb's queued, instead of relying on the skb-queue len. The skb queues used were only valid in STA-mode, as AP-mode uses per-link queues. This fixes a major regression in AP-mode, caused by the patch "wl12xx: implement Tx watermarks per AC". With that patch applied, we effectively had no regulation of Tx queues in AP-mode. Therefore a sustained high rate of Tx could cause exhaustion of the skb memory pool. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-07-07rt2x00: Implement tx_frames_pending mac80211 callback function.Gertjan van Wingerde9-0/+22
Implementing this callback function will cause mac80211 refrain from going to powersave state when there are still untransmitted TX frames in the queues. This would exactly mimic the behaviour of the legacy vendor driver which also doesn't go in powersave mode if there are still TX frames that are not transmitted. This should make powersaving and rt2x00 a better couple.

Signal this fact in the code by not providing a queue entry as a parameter, but the rt2x00 device structure and the skb directly.

2011-07-07rt2x00: Serialize TX operations on a queue.Gertjan van Wingerde2-5/+18
The rt2x00 driver gets frequent occurrences of the following error message when operating under load: phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 2. This is caused by simultaneous attempts from mac80211 to send a frame via rt2x00, which are not properly serialized inside rt2x00queue_write_tx_frame, causing the second frame to fail sending with the above mentioned error message. Fix this by introducing a per-queue spinlock to serialize the TX operations on that queue.
