However upon review of other callers I found what I believe to be a possible reference count issue in the path for handling "wifi ack" packets. To address this I have applied the same logic that is currently in place so that the sk_refcnt will be forced to stay at least 1, or we will not provide an skb to return in the sk_error_queue. ==================== Signed-off-by: David S.
