+ interfaces
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The TXQ teardown code can reference the vif data structures that are
+stored in the netdev private memory area if there are still packets on
+the queue when it is being freed. Since the TXQ teardown code is run
+after the netdevs are freed, this can lead to a use-after-free. Fix this
+by moving the TXQ teardown code to earlier in ieee80211_unregister_hw().

+Subject: [PATCH] mac80211: avoid kernel panic when building AMSDU from
+ non-linear SKB
+
+When building building AMSDU from non-linear SKB, we hit a
+kernel panic when trying to push the padding to the tail.
+Instead, put the padding at the head of the next subframe.
+This also fixes the A-MSDU subframes to not have the padding
+accounted in the length field and not have pad at all for
+the last subframe, both required by the spec.

+Subject: [PATCH] mac80211: always account for A-MSDU header changes
+
+In the error path of changing the SKB headroom of the second
+A-MSDU subframe, we would not account for the already-changed
+length of the first frame that just got converted to be in
+A-MSDU format and thus is a bit longer now.
+
+Fix this by doing the necessary accounting.
+
+It would be possible to reorder the operations, but that would
+make the code more complex (to calculate the necessary pad),
+and the headroom expansion should not fail frequently enough
+to make that worthwhile.

+Subject: [PATCH] mac80211: fix a race between restart and CSA flows
+
+We hit a problem with iwlwifi that was caused by a bug in
+mac80211. A bug in iwlwifi caused the firwmare to crash in
+certain cases in channel switch. Because of that bug,
+drv_pre_channel_switch would fail and trigger the restart
+flow.
+Now we had the hw restart worker which runs on the system's
+workqueue and the csa_connection_drop_work worker that runs
+on mac80211's workqueue that can run together. This is
+obviously problematic since the restart work wants to
+reconfigure the connection, while the csa_connection_drop_work
+worker does the exact opposite: it tries to disconnect.
+
+Fix this by cancelling the csa_connection_drop_work worker
+in the restart worker.
+

+<FW CRASH!>
+-CS FAILED-->
+ | |
+ | cancel_work(CSA)
+ schedule |
+ CSA work |
+ | |
+ Race between those 2
+
+But this is not possible because we flush the workqueue
+in the restart worker before we cancel the CSA worker.
+That would be bullet proof if we could guarantee that
+we schedule the CSA worker only from the iface_work
+which runs on the workqueue (and not on the system's
+workqueue), but unfortunately we do have an instance
+in which we schedule the CSA work outside the context
+of the workqueue (ieee80211_chswitch_done).
+
+Note also that we should probably cancel other workers
+like beacon_connection_loss_work and possibly others
+for different types of interfaces, at the very least,
+IBSS should suffer from the exact same problem, but for
+now, do the minimum to fix the actual bug that was actually
+experienced and reproduced.

+Subject: [PATCH] mac80211: Fix station bandwidth setting after channel
+ switch
+
+When performing a channel switch flow for a managed interface, the
+flow did not update the bandwidth of the AP station and the rate
+scale algorithm. In case of a channel width downgrade, this would
+result with the rate scale algorithm using a bandwidth that does not
+match the interface channel configuration.
+
+Fix this by updating the AP station bandwidth and rate scaling algorithm
+before the actual channel change in case of a bandwidth downgrade, or
+after the actual channel change in case of a bandwidth upgrade.

+Subject: [PATCH] mac80211: don't Tx a deauth frame if the AP forbade Tx
+
+If the driver fails to properly prepare for the channel
+switch, mac80211 will disconnect. If the CSA IE had mode
+set to 1, it means that the clients are not allowed to send
+any Tx on the current channel, and that includes the
+deauthentication frame.
+
+Make sure that we don't send the deauthentication frame in
+this case.
+
+In iwlwifi, this caused a failure to flush queues since the
+firmware already closed the queues after having parsed the
+CSA IE. Then mac80211 would wait until the deauthentication
+frame would go out (drv_flush(drop=false)) and that would
+never happen.
