There is a possible issue with the use, or lack thereof of sk_refcnt and sk_wmem_alloc in the wifi ack status functionality. Specifically if a socket were to request acknowledgements, and the socket were to have sk_refcnt drop to 0 resulting in it waiting on sk_wmem_alloc to reach 0 it would be possible to have sock_queue_err_skb orphan the last buffer, resulting in __sk_free being called on the socket. After this the buffer is enqueued on sk_error_queue, however the queue has already been flushed resulting in at least a memory leak, if not a data corruption.
