2011-09-13iwlagn: fix stack corruptionJohannes Berg
Alexander reported a strange crash in iwlagn that Meenakshi and Wey couldn't reproduce. I just ran into the same issue and tracked it down to stack corruption. This fixes it. The problem was introduced in commit 4b8b99b6e650d0527f3a123744b7459976581d14 Author: Wey-Yi Guy <wey-yi.w.guy@intel.com> Date: Fri Jul 8 14:29:48 2011 -0700 iwlagn: radio sensor offset in le16 format Cc: Wey-Yi Guy <wey-yi.w.guy@intel.com> Cc: Meenakshi Venkataraman <meenakshi.venkataraman@intel.com> Reported-by: Alexander Diewald <alex@diewald.cc> Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2011-09-13ath9k: Fix kernel panic on unplugging the deviceMohammed Shafi Shajakhan
when the device is yanked out ath_pci_remove starts doing the cleanups, unregistering the hardware etc. so we should bail out immediately when we get drv_flush callback from mac80211 when the card is being unplugged. the panic occurs after we had associated to an AP.

2011-09-06ath6kl: Fix AP mode connect event parsing and TIM updatesJouni Malinen
This cleans up the connect event parsing by defining a union in struct wmi_connect_event to match with the three possible sets of fields that the target uses depending on which type of connect event is being indicated. In addition, two AP cases are now separated from ath6kl_connect_event() so that correct field names can be used to make it actually possible to understand what the code is doing. The bug hiding in the previous mess was in parsing the AID incorrectly when processing the new station connecting event in AP mode. The fix here for that is also fixing TIM updates for PS buffering to use the correct AID. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2011-09-05athk6l: Fix channel list processing in scan requestsJouni Malinen
Limit the length of the channel list to WMI_MAX_CHANNELS to avoid rejection of the request in wmi.c. Since there is not really much point in using a specific list of more than 32 channels, drop the channel list if more channels are specified and scan all channels. Fix cfg80211 scan API use: ar->scan_req must be set only if returning success from scan() handler. The previous version would result in use of freed memory and likely kernel panic should the scan request fail to be sent to the target.

A well-placed interrupt between writing the index register and reading the data register could change the index register on us, which will return wrong data. Add the necessary lock.

2011-09-02ath6kl: read fwlog from firmware ring bufferKalle Valo
Firmare sends the logs only when it's internal ring buffer is full. But if firmware crashes we need to retrieve the latest logs through diagnose window. This is now done everytime the debugfs file is read. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-09-02ath6kl: cleanup diagnose window read and write functionsKalle Valo
Just to make them a bit easier to read and unify naming. 32 suffix in the function name means that it will be a 32 bit transfer. If there's no number a buffer is transfered instead.
