If anyone has any objections, please let me know. ------------------ From: Eliad Peller commit dac211ec10d268b9d09000093a9fa2ac1773894f upstream. ieee80211_rx_mgmt_auth() doesn't handle denied authentication properly - it authenticates the station and waits for association (for 5 seconds) instead of failing the authentication. Fix it by destroying auth_data and bailing out instead. Signed-off-by: Eliad Peller Acked-by: Johannes Berg Signed-off-by: John W.
