In order to support pre-populating the P1K cache in iwlwifi hardware for WoWLAN, we need to calculate the P1K for the current IV32. Allow drivers to get the P1K for any given IV32 instead of for a given packet, but keep the packet-based version around as an inline.

In order to implement GTK rekeying, the device needs to be able to encrypt frames with the right PN/IV and check the PN/IV in RX frames. To be able to tell it about all those counters, we need to be able to get them from mac80211, this adds the required API.

The current rx->queue value is slightly confusing. It is set to 16 on non-QoS frames, including data, and then used for sequence number and PN/IV checks. Until recently, we had a TKIP IV checking bug that had been introduced in 2008 to fix a seqno issue. Before that, we always used TID 0 for checking the PN or IV on non-QoS packets. Go back to the old status for PN/IV checks using the TID 0 counter for non-QoS by splitting up the rx->queue value into "seqno_idx" and "security_idx" in order to avoid confusion in the future. They each have special rules on the value used for non- QoS data frames. Since the handling is now unified, also revert the special TKIP handling from my patch "mac80211: fix TKIP replay vulnerability".

Just like TKIP and CCMP, CMAC has the PN race. It might not actually be possible to hit it now since there aren't multiple ACs for management frames, but fix it anyway. Also move scratch buffers onto the stack. Signed-off-by: NJohannes Berg <johannes.berg@intel.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

Since we can process multiple packets at the same time for different ACs, but the PN is allocated from a single counter, we need to use an atomic value there. Use atomic64_t to make this cheaper on 64-bit platforms, other platforms will support this through software emulation, see lib/atomic64.c. We also need to use an on-stack scratch buf so that multiple packets won't corrupt each others scratch buffers. Signed-off-by: NJohannes Berg <johannes.berg@intel.com> Signed-off-by: NJohn W.

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.

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: NArik Nemtsov <arik@wizery.com> Signed-off-by: NLuciano Coelho <coelho@ti.com>

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.

The functions that create the tx descriptor structure do not operate on a queue entry at all. Signal this fact in the code by not providing a queue entry as a parameter, but the rt2x00 device structure and the skb directly. This patch is a preparation for reducing the time a queue is locked for a tx operation.

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.
