Subject: [PATCH v1 00/27] Convert server-side NFSv2 XDR to use xdrgen
Date: Wed, 16 Sep 2026 12:28:29 -0400 [thread overview]
Message-ID: <20260916162859.2051-1-cel@kernel.org> (raw)
Replace NFSD's NFSv2 XDR encoders and decoders with code that is
mechanically generated directly from the NFSv2 RPC language
specification.
The benefits for NFSv2 are marginal. When we eventually 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.
These patches have been lightly tested with fstests run against an
xfs export.
Chuck Lever (27):
Documentation: Add the RPC language description of NFSv2
NFSD: Add infrastructure for generating NFSv2 XDR encoders and
decoders
NFSD: Use xdrgen-generated NFSv2 protocol definitions
NFSD: Remove '#include "xdr.h"' from fs/nfsd/xdr3.h
NFSD: Relocate the NFSv2 XDR storage union into nfsproc.c
NFSD: Use xdrgen XDR functions for the NFSv2 NULL procedure
NFSD: Use xdrgen XDR functions for NFSv2 GETATTR procedure
