From: Jouni Malinen Date: Sun, 8 Mar 2020 11:11:50 +0000 (+0200) Subject: RSN: Stop 4-way handshake if scan results are not available X-Git-Tag: hostap_2_10~1655 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c7d293024b8f122fcfc7d0474730299b98c1087e;p=thirdparty%2Fhostap.git RSN: Stop 4-way handshake if scan results are not available While there may have initially been cases where the RSNE from Beacon/Probe Response frames was not available from some drivers, it is now more valuable to notice if such a case were to be hit with drivers that are always expected to have such information available. As such, make it a fatal error if the scan results for the current AP are not available to check the RSNE/RSNXE in EAPOL-Key msg 3/4.
