It's possible for wpa_supplicant to exit with an outstanding requested_scan pending. This can lead to a stall condition where scanning no longer occurs. https://mail.gnome.org/archives/networkmanager-list/2016-June/msg00117.html (cherry picked from commit 899d7e5cb1eb3bddaf92de3644c49c9f634b675e) --- >From eed8fd2e43d244caa856d9993e750ff19ba62fd7 Mon Sep 17 00:00:00 2001 > > From: Tony Espy <[email protected]> Date: Thu, 16 Jun 2016 15:07:32 -0400 Subject: [PATCH] wifi: clear WiFi requested_scan if suppl goes INACTIVE It's possible for wpa_supplicant to transition to INACTIVE state with an outstanding requested_scan pending.
