From c1f4c9ede3c799da9f920c1df9ce524145781637 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 4 Nov 2016 10:27:52 +0100 Subject: mac80211: update A-MPDU flag on tx dequeue MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The sequence number counter is used to derive the starting sequence number. Since that counter is updated on tx dequeue, the A-MPDU flag needs to be up to date at the tme of dequeue as well. This patch prevents sending more A-MPDU frames after the session has been terminated and also ensures that aggregation starts right after the session has been established Fixes: bb42f2d13ffc ("mac80211: Move reorder-sensitive TX handlers to after TXQ dequeue") Signed-off-by: Felix Fietkau Acked-by: Toke Høiland-Jørgensen Signed-off-by: Johannes Berg --- net/mac80211/tx.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'net/mac80211/tx.c') diff --git a/net/mac80211/tx.c b/net/mac80211/tx.c index 1c56abc49627..d08a8492a846 100644 --- a/net/mac80211/tx.c +++ b/net/mac80211/tx.c @@ -3426,6 +3426,11 @@ begin: goto begin; } + if (test_bit(IEEE80211_TXQ_AMPDU, &txqi->flags)) + info->flags |= IEEE80211_TX_CTL_AMPDU; + else + info->flags &= ~IEEE80211_TX_CTL_AMPDU; + if (info->control.flags & IEEE80211_TX_CTRL_FAST_XMIT) { struct sta_info *sta = container_of(txq->sta, struct sta_info, sta); -- cgit v1.2.3
