I’ve posted an updated version of my “Karma” patch for HostAP (hostap_0_7_2-775-g9fc6aa9). This patch adds Karma-style automatic probe response, in addition to PEAP/MSCHAPv2 authentication logging (think all-in-one FreeRadius-WPE). See the Wireless page for a link to the old Hostap 0.6.9 patch and the newer version.
