Como se describe en el informe de Gerrard [1], existen casos de uso en los que una qdisc secundaria netem hará que la devolución de llamada de encolado de la qdisc primaria sea reentrante. En el caso de ets, no habrá un UAF, pero el código agregará el mismo clasificador a la lista dos veces, lo que causará corrupción de memoria. Además de verificar que qlen sea cero, este parche verifica si la clase ya se agregó a active_list (cl_is_active) antes de realizar la adición para atender el caso reentrante.
