Descriptions

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix double put of request If a netfs request finishes during the pause loop, it will have the ref
that belongs to the IN_PROGRESS flag removed at that point - however, if it
then goes to the final wait loop, that will *also* put the ref because it
sees that the IN_PROGRESS flag is clear and incorrectly assumes that this
happened when it called the collector. In fact, since IN_PROGRESS is clear, we shouldn't call the collector again
since it's done all the cleanup, such as calling ->ki_complete(). Fix this by making netfs_collect_in_app() just return, indicating that
we're done if IN_PROGRESS is removed.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netfs: Corregir doble put de solicitud Si una solicitud netfs finaliza durante el bucle de pausa, tendrá la referencia que pertenece al indicador IN_PROGRESS eliminada en ese punto; sin embargo, si luego va al bucle de espera final, eso *también* pondrá la referencia porque ve que el indicador IN_PROGRESS está limpio y asume incorrectamente que esto sucedió cuando llamó al recopilador. De hecho, como IN_PROGRESS está limpio, no deberíamos volver a llamar al recopilador ya que ha hecho toda la limpieza, como llamar a ->ki_complete(). Corrija esto haciendo que netfs_collect_in_app() simplemente regrese, lo que indica que hemos terminado si se elimina IN_PROGRESS.
