| * ath9k: fix the return value of ath_stoprecvFelix Fietkau2011-04-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The patch 'ath9k_hw: fix stopping rx DMA during resets' added code to detect a condition where rx DMA was stopped, but the MAC failed to enter the idle state. This condition requires a hardware reset, however the return value of ath_stoprecv was 'true' in that case, which allowed it to skip the reset when issuing a fast channel change.

| * ath9k_hw: fix stopping rx DMA during resetsFelix Fietkau2011-04-124-16/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During PHY errors, the MAC can sometimes fail to enter an idle state on older hardware (before AR9380) after an rx stop has been requested. This typically shows up in the kernel log with messages like these: ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath9k/recv.c:504 ath_stoprecv+0xcc/0xf0 [ath9k]() Call Trace: [<8023f0e8>] dump_stack+0x8/0x34 [<80075050>] warn_slowpath_common+0x78/0xa4 [<80075094>] warn_slowpath_null+0x18/0x24 [<80d66d60>] ath_stoprecv+0xcc/0xf0 [ath9k] [<80d642cc>] ath_set_channel+0xbc/0x270 [ath9k] [<80d65254>] ath_radio_disable+0x4a4/0x7fc [ath9k] When this happens, the state that the MAC enters is easy to identify and does not result in bogus DMA traffic, however to ensure a working state after a channel change, the hardware should still be reset. This patch adds detection for this specific MAC state, after which the above warnings completely disappear in my tests.

| | | | | | | | | | | | | | | | | | | | | | | | | | Some clients seem to rely upon the reception of BlockAckReqs to flush their rx reorder buffer. In order to fix aggregation for these clients carl9170 should set IEEE80211_TX_STAT_AMPDU_NO_BACK to generate a BlockAckReq if the transmission of an AMPDU subframe fails.

* ath9k: Fix kernel panic caused by invalid rate index access.Senthil Balasubramanian2011-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the recent tx status optimization in mac80211, we bail out as and and when invalid rate index is found. So the behavior of resetting rate idx to -1 and count to 0 has changed for the rate indexes that were not part of the driver's retry series. This has resulted in ath9k using incorrect rate table index which caused the system to panic. Ideally ath9k need to loop only for the indexes that were part of the retry series and so simply use hw->max_rates as the loop counter. Pasted the stack trace of the panic issue for reference.

| | | | | | | | | | | | | | | | | | | | | | Some clients seems to keep track of their reorder window even after an aggregation session has been disabled. This causes issues if there are still retried but not completed frames pending for the TID.

| * ath9k: improve reliability of beacon transmission and stuck beacon handlingFelix Fietkau2011-03-143-74/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ath9k calls ath9k_hw_stoptxdma every time it sends a beacon, however there is not much point in doing that if the previous beacon and mcast traffic went out properly. On AR9380, calling that function too often can result in an increase of stuck beacons due to differences in the handling of the queue enable/disable functionality. With this patch, the queue will only be explicitly stopped if the previous data frames were not sent successfully. With the beacon code being the only remaining user of ath9k_hw_stoptxdma, this function can be simplified in order to remove the now pointless attempts at waiting for transmission completion, which would never happen at this point due to the different method of tx scheduling of the beacon queue.

This patch uses a few MAC features to abort DMA globally instead of iterating over all hardware queues and attempting to stop them individually. Not only is that faster and works with a shorter timeout, it also makes the process much more reliable. With this change, I can no longer trigger these messages on AR9380, and on AR9280 they become much more rare. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

| * ath9k: remove support for the FIF_PROMISC_IN_BSS filter flagFelix Fietkau2011-03-111-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware rx filter flag triggered by FIF_PROMISC_IN_BSS is overly broad and covers even frames with PHY errors. When this flag is enabled, this message shows up frequently during scanning or hardware resets: ath: Could not stop RX, we could be confusing the DMA engine when we start RX up Since promiscuous mode is usually not particularly useful, yet enabled by default by bridging (either used normally in 4-addr mode, or with hacks for various virtualization software), we should sacrifice it for better reliability during normal operation. This patch leaves it enabled if there are active monitor mode interfaces, since it's very useful for debugging.

| | | | | | | | | | | | | | | | | | | | It seems ath5k has issues receiving broadcast packets (ARPs) when using multiple STA interfaces associated with multiple APs.

| * mac80211: make tx() operation return voidJohannes Berg2011-02-259-24/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.
