Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com> Cc: Rafael Mendonca <rafaelmendsr@...il.com>, Johannes Berg <johannes.berg@...el.com>, linux-wireless@...r.kernel.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] wifi: mac80211: mlme: Fix double unlock on assoc success handling Commit 6911458dc428 ("wifi: mac80211: mlme: refactor assoc success handling") moved the per-link setup out of ieee80211_assoc_success() into a new function ieee80211_assoc_config_link() but missed to remove the unlock of 'sta_mtx' in case of HE capability/operation missing on HE AP, which leads to a double unlock: ieee80211_assoc_success() { ... ieee80211_assoc_config_link() { ... if (!(link->u.mgd.conn_flags & IEEE80211_CONN_DISABLE_HE) && (!elems->he_cap || !elems->he_operation)) { mutex_unlock(&sdata->local->sta_mtx); ... } ... } ... mutex_unlock(&sdata->local->sta_mtx); ... } Fixes: 6911458dc428 ("wifi: mac80211: mlme: refactor assoc success handling") Signed-off-by: Rafael Mendonca <rafaelmendsr@...il.com> --- net/mac80211/mlme.c | 1 - 1 file changed, 1 deletion(-) diff --git a/net/mac80211/mlme.c b/net/mac80211/mlme.c index 5265d2b6db12..6ca9c4f2775c 100644 --- a/net/mac80211/mlme.c +++ b/net/mac80211/mlme.c @@ -4040,7 +4040,6 @@ static bool ieee80211_assoc_config_link(struct ieee80211_link_data *link, if (!(link->u.mgd.conn_flags & IEEE80211_CONN_DISABLE_HE) && (!elems->he_cap || !elems->he_operation)) { - mutex_unlock(&sdata->local->sta_mtx); sdata_info(sdata, "HE AP is missing HE capability/operation\n"); ret = false; -- 2.34.1
