Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ceph: blocklist the kclient when receiving corrupted snap trace

When received corrupted snap trace we don't know what exactly has
happened in MDS side. And we shouldn't continue IOs and metadatas
access to MDS, which may corrupt or get incorrect contents.

This patch will just block all the further IO/MDS requests
immediately and then evict the kclient itself.

The reason why we still need to evict the kclient just after
blocking all the further IOs is that the MDS could revoke the caps
faster.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ceph: lista de bloqueo del kclient cuando se recibe un seguimiento instantáneo corrupto. Cuando recibimos un seguimiento instantáneo corrupto, no sabemos qué ha sucedido exactamente en el lado MDS. Y no debemos continuar con el acceso de IO y metadatos a MDS, lo que puede dañar u obtener contenidos incorrectos. Este parche simplemente bloqueará todas las solicitudes IO/MDS adicionales inmediatamente y luego expulsará al propio kclient. La razón por la que todavía necesitamos desalojar al kclient justo después de bloquear todas las IO adicionales es que el MDS podría revocar los límites más rápido.
