Subject: [PATCH] mac80211: fix setting IEEE80211_KEY_FLAG_RX_MGMT for AP mode keys
Date: Sat, 29 Sep 2018 16:01:58 +0200 [thread overview]
Message-ID: <20180929140158.98894-1-nbd@nbd.name> (raw)
key->sta is only valid after ieee80211_key_link, which is called later
in this function. Because of that, the IEEE80211_KEY_FLAG_RX_MGMT is
never set when management frame protection is enabled.
Fixes: e548c49e6dc6b ("mac80211: add key flag for management keys")
