2011-07-16iwlagn: simplify TX flags assignmentsJohannes Berg
The first assignment of TX_CMD_FLG_SEQ_CTL_MSK for ack-expected mgmt frames is overwritten later in the function, so it's useless. Also, probe response frames, BACK request and others there are mutually exclusive so can be moved into an else branch.

2011-07-16iwlagn: move the Rx dispatching to the upper layerEmmanuel Grumbach
The upper layer receives a pointer to an iwl_rx_mem_buffer. I would prefer the upper layer to receive a pointer to an iwl_rx_packet, but this is impossible since the Rx path needs to add the address of the page to the skb. I may find a solution later. All the pre_rx_handler and notification code has been moved to the upper layer. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2011-07-16iwlagn: move sync_irq to transport layerEmmanuel Grumbach
Since all the irq / tasklet is now handled in the transport layer, it should give an API to ensure that all the irq / tasklet have finished running. This will allow the upper layer to release all its resources. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2011-07-16iwlagn: move the tasklet / irq to the transport layerEmmanuel Grumbach

2011-07-15mac80211: be more careful in suspend/resumeJohannes Berg
When suspending with all netdevs down, the device is stopped but we still call a number of driver callbacks that the driver might not expect. The same happens during resume, we might call a few callbacks without starting the driver. Fix this by checking open_count around more things and exiting quickly if it is 0. Also, while at this I noticed that the coverage class isn't reprogrammed after resume, so add that. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2011-07-15mac80211: allow driver access to TKIP RX P1KJohannes Berg
When the driver wants to pre-program the TKIP RX phase 1 key, it needs to be able to obtain it for the peer's TA. Add API to allow it to generate it. The generation uses a dummy on-stack context since it doesn't know the RX queue. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-07-15ath9k: improve reliability of MIC error detectionFelix Fietkau
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.

2011-07-15nl80211: advertise GTK rekey support, new triggersJohannes Berg
Since we now have the necessary API in place to support GTK rekeying, applications will need to know whether it is supported by a device.

2011-07-13mac80211: allow driver to disconnect after resumeJohannes Berg
In WoWLAN, devices may use crypto keys for TX/RX and could also implement GTK rekeying. If the driver isn't able to retrieve replay counters and similar information from the device upon resume, or if the device isn't responsive due to platform issues, it isn't safe to keep the connection up as GTK rekey messages from during the sleep time could be replayed against it. The only protection against that is disconnecting from the AP. Modifying mac80211 to do that while it is resuming would be very complex and invasive in the case that the driver requires a reconfig, so do it after it has resumed completely. In that case, however, packets might be replayed since it can then only happen after TX/RX are up again, so mark keys for interfaces that need to disconnect as "tainted" and drop all packets that are sent or received with those keys.

2011-07-13ath5k: disable 32KHz sleep clock operation by defaultFelix Fietkau
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.

2011-07-13ath9k_hw: Fix incorrect key_miss handlingSenthil Balasubramanian
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.

2011-07-11libertas: fix handling of command timeout, completion and interruptionDaniel Drake
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.
