cfg80211_conn_scan allows disabled channels at scan request. Hence probe request was seen at the disabled one. This patch ensures that disabled channel never be added into the scan request's channel list. Acked-by:

When the driver (or most likely firmware) decides which AP to use for roaming based on internal scan result processing, user space needs to be notified of PMKSA caching candidates to allow RSN pre-authentication to be used. Signed-off-by:

The commit "mac80211: stop tx before doing hw config and rate update" stops the tx queue and call drv_flush so frequently whenever a beacon got received with 11n htcap. This leads to massive "Failed to stop TX DMA" logspam on embedded hw. So the queue stop and flush should be called if and only if there is a change in the channel type. Reported-by:

Since the dawn of its time, iwlwifi has used interruptible waits to wait for synchronous commands and firmware loading. This leads to "interesting" bugs, because it can't actually handle the interruptions; for example when a command sending is interrupted it will assume the command completed fully, and then leave it pending, which leads to all kinds of trouble when the command finishes later. Since there's no easy way to gracefully deal with interruptions, fix the driver to not use interruptible waits. This at least fixes the error iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD' I have seen in P2P testing, but it is likely that there are other errors caused by this.

From time to time, we hit a WARN_ON in iwl_mac_remove_interface. This basically means that we got out of sync with mac80211: the vif we hold differs from the vif 80211 passes as parameter. Try to get some data that will help to debug this. Signed-off-by:

When a non-empty Tx queueis freed, the buffer it contains must be freed too. Since the Tx cmd are now allocated from a pool, the Tx cmd must be freed too. This patch avoids to destroy a non-empty pool of Tx cmd. Signed-off-by:

If the driver is unloaded while there is still a host command in flight, its tfd will be freed by iwl_tx_queue_free. This function is called for both types of queues: Tx queues and cmd queue. This didn't take in count the fact that in Tx queues, tfds are mapped as TO_DEVICE (besides the first TB), whereas in cmd queue, all TBs are mapped as BIDI. Hence, tx_queue_free unmapped the second (and higher) TB of each tfd in the cmd queue as TO_DEVICE, whereas they must be freed as BIDI. This means that if a multi TFD is in flight while we unload the driver (which is quite unlikely but can happen), we will get the warning below. This patch fixes this.

The way we check if there is host command that should be reclaimed is way too complicated. We should have a clear indication from the fw. The fw is expected to set the SEQ_RX_FRAME bit if the frame was originated by the fw which indicates to the driver that there is no host command to free. Somehow, there seem to have been buggy fw out there, hence the very old comment. This code checks if we have still buggy fw out there. Signed-off-by:
