Please note that this comment in ieee80211_rx_h_sta_process() is only after having went through association state validation in ieee80211_rx_h_check(). However, it looks like the sending of deauth/disassoc based on Class 2/3 frames being received in wrong state (IEEE 802.11, Clause 5.5) has been broken at some point.. mac80211 is supposed to notify userspace (hostapd) of this and hostapd would then reply with disassoc/deauth depending on the current state of the STA. The current mac80211 implementation is just silently dropping the frames. The way this used to work was by sending the ieee80211_msg_sta_not_assoc message with ieee80211_rx_mgmt() in ieee80211_rx_h_check(). -- Jouni Malinen PGP id EFC895FA - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
