Just mention something about how the bug happens please, at least. > 2+3) The issue is not that the station is not known, it's that > wl_sta->wl was null. > wl member is now completely removed from wl_sta (PATCH 2/2) and hw is > sent directly from mac80211 to the driver (so it can get hw->priv). Right, I understand that wl_sta->wl was NULL. But the driver must have some code to assign wl_sta->wl, right? And that would be called in add_sta or sta_state. Thus the reason for the crash would be that the station wasn't actually known to the driver yet. Even if that wasn't quite the reason here, I think we need to take it into account and check sta->uploaded before calling the driver, so I'd like you to submit a patch for that. johannes
