2012-02-20mac80211: timeout a single frame in the rx reorder bufferEliad Peller1-1/+1
commit 07ae2dfcf4f7143ce191c6436da1c33f179af0d6 upstream. The current code checks for stored_mpdu_num > 1, causing the reorder_timer to be triggered indefinitely, but the frame is never timed-out (until the next packet is received) Signed-off-by: Eliad Peller <eliad@wizery.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2012-02-03mac80211: fix work removal on deauth requestJohannes Berg1-11/+27
commit bc4934bc61d0a11fd62c5187ff83645628f8be8b upstream. When deauth is requested while an auth or assoc work item is in progress, we currently delete it without regard for any state it might need to clean up. Fix it by cleaning up for those items. In the case Pontus found, the problem manifested itself as such: authenticate with 00:23:69:aa:dd:7b (try 1) authenticated failed to insert Dummy STA entry for the AP (error -17) deauthenticating from 00:23:69:aa:dd:7b by local choice (reason=2) It could also happen differently if the driver uses the tx_sync callback. We can't just call the ->done() method of the work items because that will lock up due to the locking in cfg80211. This fix isn't very clean, but that seems acceptable since I have patches pending to remove this code completely.

2012-01-25mac80211: revert on-channel work optimisationsJohannes Berg7-221/+85
commit e76aadc572288a158ae18ae1c10fe395c7bca066 upstream. Backport note: This patch it's a full revert of commit b23b025f "mac80211: Optimize scans on current operating channel.". On upstrem revert e76aadc5 we keep some bits from that commit, which are needed for upstream version of mac80211. The on-channel work optimisations have caused a number of issues, and the code is unfortunately very complex and almost impossible to follow. Instead of attempting to put in more workarounds let's just remove those optimisations, we can work on them again later, after we change the whole auth/assoc design.

Since: commit 816c04fe7ef01dd9649f5ccfe796474db8708be5 Author: Christian Lamparter <chunkeey@googlemail.com> Date: Sat Apr 30 15:24:30 2011 +0200 mac80211: consolidate MIC failure report handling is possible to that we dereference rx->key == NULL when driver set RX_FLAG_MMIC_STRIPPED and not RX_FLAG_IV_STRIPPED and we are in promiscuous mode. This happen with rt73usb and rt61pci at least. Before the commit we always check rx->key against NULL, so I assume fix should be done in mac80211 (also mic_fail path has similar check).

2011-12-07mac80211: fix another race in aggregation startJohannes Berg1-45/+41
Emmanuel noticed that when mac80211 stops the queues for aggregation that can leave a packet pending. This packet will be given to the driver after the AMPDU callback, but as a non-aggregated packet which messes up the sequence number etc. I also noticed by looking at the code that if packets are being processed while we clear the WANT_START bit, they might see it cleared already and queue up on tid_tx->pending. If the driver then rejects the new aggregation session we leak the packet. Fix both of these issues by changing this code to not stop the queues at all. Instead, let packets queue up on the tid_tx->pending queue instead of letting them get to the driver, and add code to recover properly in case the driver rejects the session. (The patch looks large because it has to move two functions to before their new use.)

2011-11-28mac80211: fix race between the AGG SM and the Tx data pathEmmanuel Grumbach1-0/+14
When a packet is supposed to sent be as an a-MPDU, mac80211 sets IEEE80211_TX_CTL_AMPDU to let the driver know. On the other hand, mac80211 configures the driver for aggregration with the ampdu_action callback. There is race between these two mechanisms since the following scenario can occur when the BA agreement is torn down: Tx softIRQ drv configuration ========== ================= check OPERATIONAL bit Set the TX_CTL_AMPDU bit in the packet clear OPERATIONAL bit stop Tx AGG Pass Tx packet to the driver. In that case the driver would get a packet with TX_CTL_AMPDU set although it has already been notified that the BA session has been torn down. To fix this, we need to synchronize all the Qdisc activity after we cleared the OPERATIONAL bit. After that step, all the following packets will be buffered until the driver reports it is ready to get new packets for this RA / TID. This buffering allows not to run into another race that would send packets with TX_CTL_AMPDU unset while the driver hasn't been requested to tear down the BA session yet. This race occurs in practice and iwlwifi complains with a WARN_ON when it happens.

This was another workaround for truesize "bugs". The reason we did this was that when we orphaned the SKB it wouldn't be truesize-checked later. Now that the check is gone (and we just charge the former smaller size to the socket) there's no longer a reason to orphan the skb here.
