File System Extended Attributes in NFSv4
RFC 8276, “File System Extended Attributes in NFSv4”, is a Proposed Standard document published in December 2017 by M. Naik, M. Eshel. The canonical text is published by the RFC Editor.
Abstract
This document describes an optional feature extending the NFSv4 protocol. This feature allows extended attributes (hereinafter also referred to as xattrs) to be interrogated and manipulated using NFSv4 clients. Xattrs are provided by a file system to associate opaque metadata, not interpreted by the file system, with files and directories. Such support is present in many modern local file systems. New file attributes are provided to allow clients to query the server for xattr support, with that support consisting of new operations to get and set xattrs on file system objects.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
