I don't think there is requirement for doing a new scan here if recent scan results are available. > > When SIWAP happens, softmac drops association/authentication with the > > current network and then starts a scan for the requested BSSID.

I would say that neither should drop association either until a new association is available or it is clear that current configuration does not allow association to be created. First case would just report a new association (no disassociation reported) and second case would report disassociation to user space. > > Right now, wpa_supplicant does SIWESSID and SIWAP in quick succession, > > which causes softmac to associate twice, and that quickly confuses things. > > (I don't really understand why wpa_supplicant uses SIWAP when a BSSID > isn't specified in the config file, but...) There are two different modes and what is being described here is ap_scan=1, i.e., wpa_supplicant being responsible for requesting scanning and selecting an AP. In this mode, it is actually assumed that the driver does not do extra scans with SIWAP or SIWESSID. wpa_supplicant is telling the driver which channel (SIOCSIWFREQ), SSID, and BSSID to use. In the other mode, ap_scan=2, wpa_supplicant is only configuring the SSID and requesting the driver (or well, kernel side 802.11 management code) to figure out which AP to use. -- 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
