Las reglas de RCU son que primero debemos borrar sk->sk_dst_cache y luego llamar a dst_release(old_dst). Tenga en cuenta que sk_dst_reset(sk) implementa este protocolo correctamente, mientras que __dst_negative_advice() utiliza el orden incorrecto. Dado que ip6_negative_advice() tiene una lógica especial contra RTF_CACHE, esto significa que cada uno de los tres ->negative_advice() métodos existentes debe realizar sk_dst_reset() ellos mismos. Tenga en cuenta que la verificación de NULL dst está centralizada en __dst_negative_advice(), no es necesario duplicarla en varias devoluciones de llamada. Muchas gracias a Clement Lecigne por dar seguimiento a este problema. Este antiguo error se hizo visible después de la confirmación culpada, utilizando sockets
