In this situation the kernel is sending a low RSSI event which netdev picks up, but since we set netdev->connected so early the event is forwarded to station before IWD has fully connected. Station then tries to get a neighbor report, which may fail and cause a known frequency scan. If this is a new network the frequency scan tries to get any known frequencies in network_info which will be unset and cause a segfault. This can be avoided by ensuring that we are connected inside station_cannot_roam() rather than checking that we aren't roaming. This modification will ensure both connected and not roaming before doing a roam. --- src/station.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/station.c b/src/station.c index c532319a..5b0e7fd4 100644 --- a/src/station.c +++ b/src/station.c @@ -2007,7 +2007,7 @@ static bool station_cannot_roam(struct station *station) disabled = false; return disabled || station->preparing_roam || - station->state == STATION_STATE_ROAMING; + station->state != STATION_STATE_CONNECTED; } static void station_lost_beacon(struct station *station) -- 2.21.1
