https://bugzilla.suse.com/show_bug.cgi?id=1194603 https://bugzilla.suse.com/show_bug.cgi?id=1194603#c2 --- Comment #2 from Martin Wilck <martin.wilck@suse.com> --- I have updated TW to the latest code base (20220110), and I can't reproduce this issue. The policy for the "fi.w1.wpa_supplicant1" are defined in /etc/dbus-1/system.d/wpa_supplicant.conf. The policy allows only root to communicate with "fi.w1.wpa_supplicant1". See https://dbus.freedesktop.org/doc/dbus-daemon.1.html So, unless NetworkManager is not running as root, this should work, and it does on my system. You said on IRC that this error was first observed after the update of wpa_supplicant: * Mon Jan 10 2022 Johannes Segitz <jsegitz@suse.com> - Added hardening to systemd service(s) (bsc#1181400). Modified: * wpa_supplicant.service There were some security-related changes in this releas in the systemd service file for wpa_supplicant: ProtectSystem=full ProtectHome=read-only ProtectHostname=true ProtectKernelTunables=true ProtectKernelModules=true ProtectKernelLogs=true ProtectControlGroups=true RestrictRealtime=true But I can't see how those would affect the behavior on dbus, which is controlled by a different file, see above. Please verify that the issue disappears when you revert the update of (just) wpa_supplicant (see https://download.opensuse.org/history/), and occurs again if you apply the update again. Please provide journalctl output for the connection attempts, and describe steps to reproduce (what are you doing to activate the network connection?) -- You are receiving this mail because: You are on the CC list for the bug.
