1. Introduction
This document contains the External Data Representation (XDR)
[RFC4506] description of the NFSv4.2 protocol [RFC7862].
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 [RFC2119].
2. XDR Description of NFSv4.2
In order to facilitate implementations that support all of NFSv4.0,
NFSv4.1, and NFSv4.2, the description includes operations and other
features of NFSv4.0 and NFSv4.1 that do not apply to NFSv4.2. This
XDR specification is fully compatible with the specification for
NFSv4.0 [RFC7531], with the exception of the clientaddr4 structure,
which has been replaced by (strictly, aliased to) netaddr4, which has
the same members with the same purposes but the names have changed:
(r_netid -> na_r_netid, r_addr -> na_r_addr)
This effectively fully reconverges the NFSv4.0 [RFC7531] and NFSv4.1
[RFC5662] strands of the XDR.
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 NFSv4.2:
<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>
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:
