This was found during smoketesting as thoase started to repeadingly fail in the last weeks
File "/usr/libexec/vyos/tests/smoke/cli/test_interfaces_wireless.py", line 534, in test_wireless_security_station_address
self.assertTrue(process_named_running('hostapd'))
AssertionError: None is not true
Digging into this revealed that this is NOT related to the smoketest coding but
to hostapd/systemd instead. With a configured WIFI interface and calling:
"sudo systemctl reload-or-restart hostapd@wlan1" multiple times in a short
period caused systemd to report:
"Jul 18 16:15:32 systemd[1]: hostapd@wlan1.service: Deactivated successfully."
According to the internal systemd logic used in our version this is explained by:
/* If there's a stop job queued before we enter the DEAD state, we shouldn't act on Restart=, in order to not
* undo what has already been enqueued. */
if (unit_stop_pending(UNIT(s)))
allow_restart = false;
if (s->result == SERVICE_SUCCESS)
s->result = f;
if (s->result == SERVICE_SUCCESS) {
unit_log_success(UNIT(s));
end_state = SERVICE_DEAD;`
Where unit_log_success() generates the log message in question.
Improve the restart login in the wireless interface script and an upgrade to
hostapd solved the issue.
