Si estamos redirigiendo el skb y a\u00fan no hemos llamado a tcf_mirred_forward(), necesitamos para decirle al n\u00facleo que suelte el skb configurando el c\u00f3digo de retecci\u00f3n en SHOT. Sin embargo, si hemos llamado a tcf_mirred_forward(), el skb est\u00e1 fuera de nuestras manos y devolver SHOT conducir\u00e1 a UaF.
