All of them are caused by missing field initialization.</p> <p>In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0.</p> <p>htc_issue_send() does not initialize htc_frame_hdr::control array.
