-Subject: [PATCH] mac80211: properly free requested-but-not-started TX agg
- sessions
-
-When deleting a station or otherwise tearing down all aggregation
-sessions, make sure to delete requested but not yet started ones,
-to avoid the following scenario:
-
- * session is requested, added to tid_start_tx[]
- * ieee80211_ba_session_work() runs, gets past BLOCK_BA check
- * ieee80211_sta_tear_down_BA_sessions() runs, locks &sta->ampdu_mlme.mtx,
-   e.g. while deleting the station - deleting all active sessions
- * ieee80211_ba_session_work() continues since tear down flushes it, and
-   calls ieee80211_tx_ba_session_handle_start() for the new session, arms
-   the timer for it
- * station deletion continues to __cleanup_single_sta() and frees the
-   session struct, while the timer is armed
