| * ath9k: clean up / fix aggregation session flushFelix Fietkau2010-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tid aggregation cleanup is a bit fragile, as it discards failed subframes in some places, and retransmits them in others. This could block the cleanup of an existing aggregation session, if a retransmission for a tid is issued, yet the tid is never scheduled again because of the cleanup state. Fix this by getting rid of as many subframes as possible, as early as possible, and immediately transmitting pending subframes as regular HT frames instead of waiting for the cleanup to complete. Drop all pending subframes while keeping track of the Block ACK window during aggregate tx completion to prevent sending out stale subframes, which could confuse the receiver side.

| * ath9k: fix an aggregation start related race conditionFelix Fietkau2010-09-21
| | | | | | | | | | | | | | | | | | | | | | | | A new aggregation session start can be issued by mac80211, even when the cleanup of the previous session has not completed yet. Since the data structure for the session is not recreated, this could corrupt the block ack window and lock up the aggregation session. Fix this by delaying the new session until the old one has been cleaned up. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W.

| * ath5k: Keep last descriptor in queueBruno Randolf2010-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we return a TX descriptor to the pool of available descriptors, while a queues TXDP still points to it we could potentially run into all sorts of troube. It has been suggested that there is hardware which can set the descriptors done bit before it reads ds_link and moves on to the next descriptor. While the documentation says this is not true for newer chipsets (the descriptor contents are copied to some internal memory), we don't know about older hardware. To be safe, we always keep the last descriptor in the queue, and avoid dangling TXDP pointers. Unfortunately this does not fully resolve the problem - queues still get stuck! This is similar to what ath9k does. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * ath5k: Use four hardware queuesBruno Randolf2010-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare ath5k for WME by using four hardware queues. The way we set up our queues matches the mac80211 queue priority 1:1, so we don't have to do any mapping for queue numbers. Every queue uses 50 of the total 200 available transmit buffers, so the DMA memory usage does not increase with this patch, but it might be good to fine-tune the number of buffers per queue later (depending on the CPU speed and load, and the speed of the medium access, it might not be big enough).

| * ath9k: fix enabling ANI / tx monitor after bg scanLuis R. Rodriguez2010-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ath9k's entire logic with SC_OP_SCANNING is incorrect due to the way mac80211 currently implements the scan complete callback and we handle it in ath9k. This patch removes the flag completely in preference for the SC_OP_OFFCHANNEL which is really what we wanted. The scanning flag was used to ensure we reset ANI to the old values when we go back to the home channel, but if we are offchannel we use some defaults. The flag was also used to re-enable the TX monitor. Without this patch we simply never re-enabled ANI and the TX monitor after going offchannel. This means that after one background scan we are prone to noise issues and if we had a TX hang we would not recover. To get this to work properly we must enable ANI after we have configured the beacon timers, otherwise hardware acts really oddly. This patch has stable fixes which apply down to [2.6.36+], there *may* be a to fix this on older kernels but requires a bit of work since this patch relies on the new mac80211 flag IEEE80211_CONF_OFFCHANNEL which was introduced as of 2.6.36.

| * ath9k: fix regression on beacon loss after bgscanLuis R. Rodriguez2010-09-16

There are also other reasons why we would get a reset and if we are not off channel we always need to resynch our beacon timers, because a reset will clear them. This bug is a regression introduced on 2.6.36. The order of the changes are as follows: 5ee08656 - Sat Jul 31 - ath9k: prevent calibration during off-channel activity a0daa0e7 - Tue Jul 27 - Revert "mac80211: fix sw scan bracketing" 543708be - Fri Jun 18 - mac80211: fix sw scan bracketing mcgrof@tux ~/linux-2.6-allstable (git::master)$ git describe \ --contains 5ee0865615f65f84e6ee9174771a6716c29e08e1 v2.6.36-rc1~43^2~34^2~22 mcgrof@tux ~/linux-2.6-allstable (git::master)$ git describe \ --contains a0daa0e7592ada797d6835f11529097aabc27ad2 v2.6.36-rc1~571^2~64^2~13 mcgrof@tux ~/linux-2.6-allstable (git::master)$ git describe \ --contains 543708be320d7df692d24b349ca01a947b340764 v2.6.36-rc1~571^2~107^2~187 So 5ee08656 would have worked if a0daa0e7 was not committed but it was so this means 5ee08656 was broken since it assumed that when we were in the channel change routine the scan flag would be lifted. As it turns out the scan flag will be set when we are already on the home channel. For more details refer to: http://code.google.com/p/chromium-os/issues/detail?id=5715 These issues will need to be considered for our solution on reshifting the scan complete callback location on mac80211 on current development kernel work.

| * ath9k: fix power save race conditionsLuis R. Rodriguez2010-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ath9k has a race on putting the chip into network sleep and having registers read from hardware. The race occurs because although ath9k_ps_restore() locks its own callers it makes use of some variables which get altered in the driver at different code paths. The variables are the ps_enabled and ps_flags. This is easily reprodicible in large network environments when roaming with the wpa_supplicant simple bgscan. You'd get some 0xdeadbeef read out on certain registers such as: ath: timeout (100000 us) on reg 0x806c: 0xdeadbeef & 0x01f00000 != 0x00000000 ath: RX failed to go idle in 10 ms RXSM=0xdeadbeef ath: timeout (100000 us) on reg 0x7000: 0xdeadbeef & 0x00000003 != 0x00000000 ath: Chip reset failed The fix is to protect the ath9k_config(hw, IEEE80211_CONF_CHANGE_PS) calls with a spin_lock_irqsave() which will disable contendors for these variables from interrupt context, timers, re-entry from mac80211 on the same callback, and most importantly from ath9k_ps_restore() which is the only call which will put the device into network sleep.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use common ath key management functions in ath5k. This fixes problems with HW encryption in AP mode, which was broken in the ath5k implementation. Before (with the ath5k implementation) only one client could connect to the AP using HW encryption and WPA. When a second client connected, the first client was not able to send/receive any more packets. Because of the problems with HW encryption, software encryption was always used in AP mode, which resulted in a high CPU load (and/or low thruput) on embedded devices. Instead of trying to fix the implementation in ath5k it makes more sense to share the code with ath9k. This also enables HW encryption for AP mode again.

Minor changes have been made: - renamed ath9k_* to ath_* - replaced ah->caps.keycache_size with common->keymax - removed ATH9K_IS_MIC_ENABLED since it is always true. - the AR_PCU_MIC_NEW_LOC_ENA flag is replaced with (splitmic == 0).

| * ath9k_hw: handle rx key missFelix Fietkau2010-09-14
| | | | | | | | | | | | | | | | | | | | | | | | If AR_KeyMiss is set in the rx descriptor and AR_RxFrameOK is unset, the hardware could not locate a valid key during a decryption attempt. In this case, the frame must not be reported as decrypted, otherwise mac80211 sees only random garbage. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W.

| * ath9k: fix BSSID mask calculationFelix Fietkau2010-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the time the .add_interface driver op is called, the interface has not been marked as running yet, so ieee80211_iterate_active_interfaces will not pass it to the iterator function. Because of this, the calculated BSSID mask is wrong, which breaks multi-BSS operation. Additionally, the current way of comparing all addresses against each other is pointless, as the hardware only uses the hardware MAC address and the BSSID mask for matching the destination address, so all the address array reallocation is completely unnecessary. This patch simplifies the logic by setting the initial mask bytes to 0xff and removing all bits in the iterator call that don't match the hardware MAC address. It also calls the iterator for the vif that was passed to add_interface() Signed-off-by: Felix Fietkau <nbd@openwrt.org> Tested-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W.

| * ath9k_htc: Fix CPU usage issue during scan periodRajkumar Manoharan2010-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The CPU consumption during the scan period is high, since the register write go over Interrupt endpoint. On downloading the firmware to the target, the USB descriptors are 'patched' to change the type of the endpoints from Interrupt to Bulk. With this fix, the CPU usage during a scan run comes down to acceptable levels. Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
