From ae750570b6f8d9d2b723eefd136896a2dbdfa0d2 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Mon, 24 Feb 2020 20:04:21 +0200 Subject: [PATCH] tests: WPS PBC session overlap detection with single BSSID selected Update grpform_pbc_overlap not to require PBC session overlap to be detected since in this sequence a single BSSID is specified and other APs can be ignored while checking for session overlap. Add other test cases to explicitly check for the PBC session overlap detection in non-P2P and P2P cases when the BSSID is specified.
