1. Introduction
This document provides the External Data Representation Standard
(XDR) description for Network File System version 4 (NFSv4) minor
version 1.
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [1].
1.2. Code Components Licensing Notice
The XDR description and scripts for extracting the XDR description
are Code Components as described in Section 4 of "Legal Provisions
Relating to IETF Documents" [2].
2. XDR Description of NFSv4.1
This document contains the XDR ([3]) description of NFSv4.1 protocol
([4]). In order to facilitate implementations that support both
NFSv4.0 and NFSv4.1, the description includes operations and other
features of NFSv4.0 that do not apply to NFSv4.1.
The XDR description is provided in this document in a way that makes
it simple for the reader to extract into ready-to-compile form. The
reader can feed this document in the following shell script to
produce the machine readable XDR description of NFSv4.1:
Shepler, et al. Standards Track [Page 2]RFC 5662 NFSv4.1 XDR Description January 2010
<CODE BEGINS>
#!/bin/sh
grep '^ *///' | sed 's?^ */// ??' | sed 's?^ *///$??'
<CODE ENDS>
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:
<CODE BEGINS>
sh extract.sh < spec.txt > nfs4_prot.x
<CODE ENDS>
Shepler, et al. Standards Track [Page 3]RFC 5662 NFSv4.1 XDR Description January 2010
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:
