Package: wpasupplicant Version: 2.3-2 Severity: normal File: /sbin/wpa_supplicant
Dear Maintainer, While trying to debug issues related to systemd unmounting NFS shares way after the network has gone down, I ran into problems trying to stop services before wpa_supplicant initiated deauth. Even tying my service (autofs.service) to NetworkManager with After=NetworkManager.service didn't work, wireless would get disconnected before it could unmount over the net. This is because wpa_supplicant will shutdown when the dbus is disconnected, as seen in these logs: wpa_supplicant[919]: dbus: bus disconnected, terminating wpa_supplicant[919]: wlan0: Removing interface wlan0 wpa_supplicant[919]: wlan0: Request to deauthenticate - bssid=REDACTED pending_bssid=00:00:00:00:00:00 reason=3 state=COMPLETED wpa_supplicant[919]: TDLS: Tear down peers wpa_supplicant[919]: wpa_driver_nl80211_deauthenticate(addr=REDACTED reason_code=3) wpa_supplicant[919]: wlan0: Event DEAUTH (12) received wpa_supplicant[919]: wlan0: Deauthentication notification wpa_supplicant[919]: wlan0: * reason 3 (locally generated) wpa_supplicant[919]: Deauthentication frame IE(s) - hexdump(len=0): [NULL] wpa_supplicant[919]: wlan0: CTRL-EVENT-DISCONNECTED bssid=REDACTED reason=3 locally_generated=1 Since this relationship is not set in the systemd configuration, the only way to correctly shutdown services that require wireless connection is to set After=dbus.service in them. Of course, this is not evident in any way, and it can cause bugs such as #761909. I'm not sure what the solution would be in this case, I'm cc'ing the systemd maintainers since it seems to me they have tackled this kind of problems with wlan before.
