Subject: [PATCH v1 00/33] Convert server-side NFSv3 XDR to use xdrgen
Date: Wed, 23 Sep 2026 09:27:38 -0400 [thread overview]
Message-ID: <20260923132811.244160-1-cel@kernel.org> (raw)
Replace NFSD's NFSv3 XDR encoders and decoders with code that is
mechanically generated directly from the NFSv3 RPC language
specification. Unlike NFSv2, where there are at least two
incomplete language specifications and much lore, nfs3.x here is
based closely on RFC 1813.
As we convert newer NFS versions to use xdrgen, I expect a reduction
in human coding errors, improved spec compliance, and better memory
safety for those more complex NFS programs.
Chuck Lever (33):
NFSD: Report a first-batch readdir error in the reply status
Documentation: Add the RPC language description of NFSv3
NFSD: Add infrastructure for generating NFSv3 XDR encoders and
decoders
NFSD: Replace nfs3.h with nfs3xdr_gen.h
