* ath9k: Fix bug in starting aniVasanthakumar Thiagarajan2010-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are few places where ANI is started without checking if it is right to start. This might lead to a case where ani timer would be left undeleted and cause improper memory acccess during module unload. This bug is clearly exposed with paprd support where the driver detects tx hang and does a chip reset. During this reset ani is (re)started without checking if it needs to be started. This would leave a timer scheduled even after all the resources are freed and cause a panic. This patch introduces a bit in sc_flags to indicate if ani needs to be started in sw_scan_start() and ath_reset(). This would fix the following panic. This issue is easily seen with ar9003 + paprd.

* ath9k: Fix bug in the way "bf_tx_aborted" of struct ath_buf is usedVasanthakumar Thiagarajan2010-05-28
| | | | | | | | | | | | | | | | | | | | | This bug was introduced by the following commit Author: Vasanthakumar Thiagarajan <vasanth@atheros.com> Date: Thu Apr 15 17:38:46 2010 -0400 ath9k: Remove ATH9K_TX_SW_ABORTED and introduce a bool for this purpose Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(), this may result in a rate scaling with wrong feedback (number of unacked frames in this case). It is the last one in the chain of buffers for an aggregate frame that should be checked. Also it misses the initialization of this field in the buffer, this may lead to a situation where we stop the sw retransmission of failed subframes associated to this buffer.

* ath9k: remove VEOL support for ad-hocFelix Fietkau2010-05-25
| | | | | | | | | | | With VEOL, Beacon transmission in ad-hoc does not currently work.

| | | | | | | | | | | | | We tried to squeeze as much AR9003 support into this kernel release cycle but there are a few features which are still being tested and developed. Some of these features are critical to the stable operation of AR9003 so for now disable AR9003 support all together. This will get re-enabled once all necessary features are in place but very likely will not happen for 2.6.35. Reviewed-by: Don Breslin <don.breslin@atheros.com> Signed-off-by: Luis R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current way of managing beaconing in ad-hoc mode has a subtle race - the beacon obtained from mac80211 is freed in the SWBA handler rather than the TX completion routine. But transmission of beacons goes through the normal SKB queue maintained in hif_usb, leading to a situation where __skb_dequeue() in the TX completion handler goes kaput. Fix this by simply getting a beacon from mac80211 for every SWBA and free it in its completion routine. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W.

| * ath9k: Avoid corrupt frames being forwarded to mac80211.Vivek Natarajan2010-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If bit 29 is set, MAC H/W can attempt to decrypt the received aggregate with WEP or TKIP, eventhough the received frame may be a CRC failed corrupted frame. If this bit is set, H/W obeys key type in keycache. If it is not set and if the key type in keycache is neither open nor AES, H/W forces key type to be open. But bit 29 should be set to 1 for AsyncFIFO feature to encrypt/decrypt the aggregate with WEP or TKIP.

| * ath9k_hw: Fix TX interrupt mitigation settingsLuis R. Rodriguez2010-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TX interrupt mitigation reduces the number of interrupts by addressing several interrupt actions (AR_IMR_TXOK, AR_IMR_TXDESC) all in one interrupt so when enabling it discard setting the other interrupts. Without this TX interrupt mitigation would actually increase the number of interrupts two-fold. We still leave TX interrupt mitigation disabled as it is still being tested. Signed-off-by: Luis R.

| * ath9k_hw: fix noisefloor timeout handling on AR9003Felix Fietkau2010-04-27
| | | | | | | | | | | | | | | | | | | | When the noisefloor calibration times out, do not load -50 into the registers, since this might cause rx issues. Instead, leave enough time for the noise floor calibration to complete until the next check. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | Since the new AR9003 EEPROM code does tune the card for the configured tx power level, we need to fill in the correct power limits in the TPC part of the DMA descriptor.
