Mientras rfcomm_sock_connect adquiere el bloqueo sk y espera el bloqueo rfcomm, rfcomm_sock_release podr\u00eda tener el bloqueo rfcomm y llegar a un bloqueo para adquirir el bloqueo sk. Aqu\u00ed hay un flujo simplificado: rfcomm_sock_connect: lock_sock(sk) rfcomm_dlc_open: rfcomm_lock() rfcomm_sock_release: rfcomm_sock_shutdown: rfcomm_lock() __rfcomm_dlc_close: rfcomm_k_state_change: lock_sock(sk) Este parche elimina el bloqueo de sk antes de llamar a rfcomm_dlc_open para evitar el posible bloqueo y mantiene el recuento de referencia de sk para evitar el use-after-free despu\u00e9s de que se completa rfcomm_dlc_open."
