This document specifies an OPTIONAL extension to NFS version 4 minor version 2 that enables Linux Integrity Measurement Architecture metadata (IMA) to be conveyed between NFS version 4.2 servers and clients. Integrity measurement authenticates the creator of a file's content and helps guarantee the content's integrity end-to-end from creation to use.
