Would this be replacing the SSID of all BSSes in scan results with the SSID for which the latest per-SSID scan was issued? If yes, this does not sound any better than the current behavior. The driver/802.11 code should not replace the SSID value with anything else than the value received from the AP. In case of hidden SSIDs, the 802.11 implementation should maintain a list of BSSes found during the scan(s) and update the SSID (in most cases, by creating a new BSS entry) with the SSID from Probe Response frames. In other words, if the scan is done for a specific SSID (Probe Request includes that SSID), the AP that is using hidden SSIDs will likely include the SSID in Probe Response and data from that Probe Response can be used to fill in the missing pieces for the <BSSID,SSID> pair. Generating false scan results by locally guessing what the SSID could be is just plain wrong. The scan results need to be based on real frames from the APs. -- Jouni Malinen PGP id EFC895FA - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
