[0] La reproducci\u00f3n primero crea un oyente con SO_REUSEPORT. Luego, crea otro oyente en el mismo puerto y al mismo tiempo cierra el primer oyente. El segundo listen() llama a reuseport_add_sock() con el primer oyente como sk2, donde no se espera que sk2-\u0026gt;sk_reuseport_cb se borre al mismo tiempo, pero close() lo borra mediante reuseport_detach_sock(). El problema es que SCTP no sincroniza correctamente reuseport_alloc(), reuseport_add_sock() y reuseport_detach_sock(). La persona que llama a reuseport_alloc() y reuseport_{add,detach}_sock() debe proporcionar sincronizaci\u00f3n para los sockets que est\u00e1n clasificados en el mismo grupo de reuseport.
