* iwlagn: fix a race in the unmapping of the TFDsEmmanuel Grumbach2011-10-141-0/+3
| | | | | | | | | | | | | | | While inspecting the code, I saw that iwl_tx_queue_unmap modifies the read pointer of the Tx queue without taking any locks. This means that it can race with the reclaim flow. This can possibly lead to a DMA warning complaining that we unmap the same buffer twice. This is more a W/A than a fix since it is really weird to take sta_lock inside iwl_tx_queue_unmap, but it can help until we revamp the locking model in the transport layer.

* iwlagn: stop interrupts when suspendingJohannes Berg2011-10-141-1/+6
| | | | | | | | | | | | | | | | | Occasionally, the device will send interrupts while it is resuming, at a point where we are not set up again to handle them. This causes the core IRQ handling to completely disable the IRQ, and then the driver won't work again until it is reloaded/rebound. To fix this issue disable the IRQ on suspend, this will cause us to only get interrupts again after we've setup everything on resume.

* iwlagn: update beacon smarterJohannes Berg2011-10-142-2/+11
| | | | | | | | | | | | | | | | | | | Updating the beacon every time right after one was transmitted is pointless, most of the time we might not even have to update it. We will update it every time it changes, which includes from set_tim(), a callback iwlwifi didn't implement so far. This also reduces latency for clients, previously we would update the beacon right after the previous one was transmitted, and then a TIM change would only take effect after that again -- updating the beacon right after the TIM changes makes the TIM change go out to the air faster.

| | | | | | | | | | | | | | | | | | | Add uAPSD support to mac80211. This is probably not possible with all devices, so advertising it with the cfg80211 flag will be left up to drivers that want it. Due to my previous patches it is now a fairly straight-forward extension. Drivers need to have accurate TX status reporting for the EOSP frame. For drivers that buffer themselves, the provided APIs allow releasing the right number of frames, but then drivers need to set EOSP and more-data themselves. This is documented in more detail in the new code itself. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | When we cancel a scan, the completion runs only from the workqueue. This can cause the remain-on-channel scan to fail when another one was just canceled, because we're still aborting it. To fix this, run the completion inline with the lock still held before returning from iwl_scan_cancel_timeout(). Also, to avoid the scan complete work from completing a new scan prematurely, add a new STATUS_SCAN_COMPLETE bit.

* iwlagn: fix dangling scan requestJohannes Berg2011-09-271-14/+16
| | | | | | | | | | | | | | | | | | | | | | | | If iwl_scan_initiate() fails for any reason, priv->scan_request and priv->scan_vif are left dangling. This can lead to a crash later when iwl_bg_scan_completed() tries to run a pending scan request. In practice, this seems to be very rare due to the STATUS_SCANNING check earlier. That check, however, is wrong -- it should allow a scan to be queued when a reset/roc scan is going on. When a normal scan is already going on, a new one can't be issued by mac80211, so that code can be removed completely. I introduced this bug when adding off-channel support in commit 266af4c745952e9bebf687dd68af58df553cb59d.

While doing that I forgot that the mac header is copied to the TB of the TX cmd in the upper layer before the call to the transport layer. So basically we used the sequence number from mac80211... This was fine for the first assocation but after the second, mac80211 resets its counters while we don't hence a shift that led to terrible impact on performance.
