There are two cases here, but in both of them, them PMK (i.e., PSK for WPA-Personal) needs to be set just before the 4-way handshake would start. When using WPA-Personal, the PSK would be set just before (or as part of) association request. When using WPA-Enterprise (WPA-EAP), the PMK would be set after having completed IEEE 802.1X/EAP authentication (and the driver/firmware would then take care of 4-way handshake). Both cases will end up disabling the user space supplicant from taking part in 4-way handshake, i.e., it will ignore EAPOL-Key frames should they be delivered through the netdev and expects the driver/firmware to process them. -- 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
