 2018-11-17 18:22:33 +01:00
Lorenzo BianconiandFelix Fietkau fa7335bbe3 mt76: fix potential NULL pointer dereference in mt76_stop_tx_queues 
Starting from mac80211 commit adf8ed01e4fd ("mac80211: add an optional
TXQ for other PS-buffered frames") and commit 0eeb2b674f05 ("mac80211:
add an option for station management TXQ") a new per-sta queue has been
introduced for bufferable management frames.
sta->txq[IEEE80211_NUM_TIDS] is initialized just if the driver reports
the following hw flags:
- IEEE80211_HW_STA_MMPDU_TXQ
- IEEE80211_HW_BUFF_MMPDU_TXQ
This can produce a NULL pointer dereference in mt76_stop_tx_queues
since mt76 iterates on all available sta tx queues assuming they are
initialized by mac80211. This issue has been spotted analyzing the code
(it has not triggered any crash yet)

Felix Fietkau 67458301fd mt76: fix race condition in station removal 
If there are still pending packets in the tx queue when removing a station,
it could possibly lead to a call to further attempts to pull packets from
the mac80211 tx queue after it has already been removed from the scheduling
list.
Prevent this from happening by calling synchronize_rcu after deleting the
wcid pointer before further cleaning up the tx queues.
To be extra careful, ensure that mtxq->list is always initialized properly.

Also drop the useless call to mt76x02_mac_wcid_setup, which only re-assigns
the bss index of the wcid entry, but does not help with the cleanup in any
way.
