It is not ideal to work without including the WPS IE in Probe Request, but the Registrar should be able to do similar detection for session overlap using M1. If you want something better, all you need to do is to move from using WEXT to nl80211.. ;-) The spec is somewhat unclear on this, but there are couple of places which indicate that the WPS IE may not always be included in Probe Request (e.g., APs must not reject WPS based on missing WPS IE in Probe Request). -- 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
