Extensions for Opening and Delegating Files in NFSv4.2
RFC 9754, “Extensions for Opening and Delegating Files in NFSv4.2”, is a Proposed Standard document published in March 2025 by T. Haynes, T. Myklebust. The canonical text is published by the RFC Editor.
Abstract
The Network File System v4 (NFSv4) allows a client to both open a file and be granted a delegation of that file. This delegation provides the client the right to authoritatively cache metadata on the file locally. This document presents several extensions for both opening the file and delegating it to the client. This document extends NFSv4.2 (see RFC 7863).
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.
