Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ceph: blocklist the kclient when receiving corrupted snap trace<br /> <br /> When received corrupted snap trace we don&amp;#39;t know what exactly has<br /> happened in MDS side. And we shouldn&amp;#39;t continue IOs and metadatas<br /> access to MDS, which may corrupt or get incorrect contents.<br /> <br /> This patch will just block all the further IO/MDS requests<br /> immediately and then evict the kclient itself.<br /> <br /> The reason why we still need to evict the kclient just after<br /> blocking all the further IOs is that the MDS could revoke the caps<br /> faster.
