* ath9k: improve reliability of MIC error detectionFelix Fietkau2011-07-151-21/+32
| | | | | | | | | | | | | | For unicast the hardware sometimes reports MIC errors even though the frame that it received actually contains a valid MIC - on some chips this can happen frequently enough to trigger TKIP countermeasures. Fix this issue by not reporting MIC errors for unicast frames with a valid key, letting mac80211 validate the MIC instead. Additionally, strip the MIC for all frames that the hardware considers valid to avoid wasting CPU cycles re-validating it. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

* ath5k: disable 32KHz sleep clock operation by defaultFelix Fietkau2011-07-133-3/+13
| | | | | | | | | | | | | | While 32 KHz sleep clock might provide some power saving benefits, it is also a major source of stability issues, on OpenWrt it produced some reproducible data bus errors on register accesses on several different MIPS platforms. All the Atheros drivers that I can find do not enable this feature, so it makes sense to leave it disabled in ath5k as well.

* ath9k_hw: Fix incorrect key_miss handlingSenthil Balasubramanian2011-07-132-4/+2
| | | | | | | | | | | | | | | | | | | Decryping frames on key_miss handling shouldn't be done for Michael MIC failed frames as h/w would have already decrypted such frames successfully anyway. Also leaving CRC and PHY error(where the frame is going to be dropped anyway), we are left to prcoess Decrypt error for which s/w decrypt is selected anway and so having key_miss as a separate check doesn't serve anything. So making key_miss handling mutually exlusive with other RX status handling makes much more sense. This patch addresses an issue with STA not reporting MIC failure events resulting in STA being disconnected immediately.

* libertas: fix handling of command timeout, completion and interruptionDaniel Drake2011-07-114-17/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When commands time out, corruption ensues. As lbs_complete_command() is called without locking, the command node is mistakenly freed twice. Also fixed up locking here in a few other places. The nature of command timeout may be that the card didn't even acknowledge receipt of the request. Detect this case and reset dnld_sent so that other commands don't hang forever. When cmdnodes are moved between the free list and the pending list, their list heads should be reinitialized. Fixed this. Sometimes commands are completed without actually submitting them or removing them from cmdpendingq. We must remember to remove them from cmdpendingq in these cases, so handle this in lbs_complete_command(). Harmless signals generated during suspend/resume were interrupting lbs_cmd. Convert to an uninterruptible sleep to avoid this. lbs_thread must be woken up every time there is some new work to do. I found that when 2 commands are queued, ther completion of the first command would not wake up lbs_thread to submit the second. Poke lbs_thread at the end of lbs_complete_command() to fix this.

* iwlagn: Enable/disable PS poll based on RSSI and BT coex traffic stateMeenakshi Venkataraman2011-07-116-2/+150
| | | | | | | | | | | | | | | | | | | | | | | WiFi throughput drops drastically when BT is turned on, BT and WiFi are simultaneously transmitting/receiving traffic. This is particularly true when BT has higher priority over WiFi, and hence the device defers TX frames. The AP assumes that the channel is bad and reduces the data rate, implying longer airtime, which exacerbates the problem further, resulting ultimately in what is popularly called the "death-spiral" phenomenon. The use of PS-poll in such scenarios guarantees a low but consistent throughput. Since the death-spiral phenomenon is observed only when the RSSI is low, use PS-poll only when RSSI is low and disable when high, with a known hysterisis. This feature specifies the high and low thresholds and implements the callbacks registered with mac80211, which will be called when threshold events occur. iwlwifi: dynamic pspoll: optimize rssi monitor code Signed-off-by: Meenakshi Venkataraman <meenakshi.venkataraman@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.
