Hi, So ... I have no idea why you're CC'ing all kinds of people who never had anything to do with this driver, or haven't worked on WiFi in like a decade or so ... Please don't. Even I should've been CC'ed with a different address, at most. I also have no idea who's maintaining this driver now though, if anyone. I have hardware if someone wants it ;-) > In order to avoid potential data races and leading dereference of a NULL > pointer, acquire the queue lock before any work with the queue is done and > replace all skb_* calls with their lockless version. You should explain why the locking changes are OK. johannes
