It looks like some Windows NDIS drivers (e.g., Intel) do not clear the PMKID list even when wpa_supplicant explicitly sets the list to be empty. In such a case, the driver ends up trying to use PMKSA caching with the AP and wpa_supplicant may not have the PMK that would be needed to complete 4-way handshake. RSN processing already had some code for aborting PMKSA caching by sending EAPOL-Start. However, this was not triggered in this particular case where the driver generates the RSN IE. With this change, this case is included, too, and the failed PMKSA caching attempt is cleanly canceled and wpa_supplicant can fall back to full EAP authentication.
wpa_supplicant and hostapd v0.6.x --------------------------------- Copyright (c) 2002-2007, Jouni Malinen <j@w1.fi> and contributors All Rights Reserved. These program is dual-licensed under both the GPL version 2 and BSD license. Either license may be used at your option. This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files have been moved around in v0.6.x releases and compared to earlier releases, the programs are now build by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
