La herramienta permite guardar el estado de uno o varios procesos y luego continuar desde el punto guardado, incluso despu\u00e9s de reiniciar el sistema o en otro servidor sin interrumpir las conexiones de red ya establecidas. El c\u00f3digo del proyecto est\u00e1 escrito en C y se distribuye bajo la licencia GPLv2. CRIU se utiliza en sistemas de gesti\u00f3n de contenedores como OpenVZ, LXC\/LXD y Docker. Los cambios necesarios para el funcionamiento de CRIU est\u00e1n incluidos en la composici\u00f3n principal del n\u00facleo de Linux.      <\/p>\n<p>Entre las \u00e1reas de aplicaci\u00f3n de la tecnolog\u00eda CRIU se destacan la reinicializaci\u00f3n del sistema operativo sin interrumpir la continuidad de la ejecuci\u00f3n de procesos de larga duraci\u00f3n, la migraci\u00f3n en vivo de contenedores aislados, la aceleraci\u00f3n del inicio de procesos lentos (se puede comenzar a trabajar desde un estado guardado despu\u00e9s de la inicializaci\u00f3n), realizar actualizaciones del n\u00facleo sin reiniciar servicios, guardar peri\u00f3dicamente el estado de tareas computacionales de larga duraci\u00f3n para reanudar el trabajo en caso de un fallo, equilibrar la carga en nodos dentro de cl\u00fasteres, duplicar procesos en otra m\u00e1quina (fork en un sistema remoto) y crear instant\u00e1neas de aplicaciones de usuario en ejecuci\u00f3n para su an\u00e1lisis en otro sistema o en caso de que se necesite deshacer acciones posteriores en el programa.     <\/p>\n<p>En esta nueva versi\u00f3n:  <\/p>\n<ul>\n<li class=\"l\"> Se ha a\u00f1adido soporte para la arquitectura RISC-V.\n<li class=\"l\"> Se ha a\u00f1adido soporte para el mecanismo PIDFD, que permite utilizar identificadores inmutables vinculados a procesos originales (un PID normal puede ser asignado a otro proceso despu\u00e9s de que el proceso asociado a ese PID haya finalizado).\n<li class=\"l\"> Para la plataforma ARM64 se ha implementado el soporte para extensiones de autenticaci\u00f3n de punteros (PAC - Pointer Authentication Code), que proporcionan verificaci\u00f3n de direcciones de retorno utilizando firmas digitales que se almacenan en los bits superiores no utilizados del propio puntero.\n<li class=\"l\"> Se han ampliado las capacidades de guardar y restaurar el estado de aplicaciones que utilizan la tecnolog\u00eda NVIDIA CUDA.\n<li class=\"l\"> Se ha proporcionado la posibilidad de elegir el backend de bloqueo de red en la etapa de construcci\u00f3n, sin necesidad de modificar el c\u00f3digo. El backend se puede cambiar pasando el par\u00e1metro NETWORK_LOCK_DEFAULT a la utilidad make, que admite los valores \u00abNETWORK_LOCK_IPTABLES\u00bb, \u00abNETWORK_LOCK_NFTABLES\u00bb y \u00abNETWORK_LOCK_SKIP\u00bb.\n<li class=\"l\"> Se ha incluido el soporte para la generaci\u00f3n de archivos coredump para las arquitecturas Aarch64 y ARM.    <\/ul>\n<p>Fuente: <a
