Network File System (NFS) Version 4
External Data Representation Standard (XDR) Description
Abstract
The Network File System (NFS) version 4 protocol is a distributed
file system protocol that owes its heritage to NFS protocol version 2
(RFC 1094) and version 3 (RFC 1813). Unlike earlier versions, the
NFS version 4 protocol supports traditional file access while
integrating support for file locking and the MOUNT protocol. In
addition, support for strong security (and its negotiation), COMPOUND
operations, client caching, and internationalization has been added.
Of course, attention has been applied to making NFS version 4 operate
well in an Internet environment.
RFC 7530 formally obsoletes RFC 3530. This document, together with
RFC 7530, replaces RFC 3530 as the definition of the NFS version 4
protocol.

1. Introduction
This document contains the External Data Representation (XDR)
[RFC4506] description of the NFSv4.0 protocol [RFC7530].
2. XDR Description of NFSv4.0
The XDR description is provided in this document in a way that makes
it simple for the reader to extract it into a form that is ready to
compile. The reader can feed this document in the following shell
script to produce the machine-readable XDR description of NFSv4.0:
#!/bin/sh
grep "^ *///" | sed 's?^ */// ??' | sed 's?^ *///$??'
That is, if the above script is stored in a file called "extract.sh",
and this document is in a file called "spec.txt", then the reader
can do:
sh extract.sh < spec.txt > nfs4_prot.x
The effect of the script is to remove leading white space from each
line, plus a sentinel sequence of "///".
The XDR description, with the sentinel sequence, follows:
