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. Changes in v2: - Include the generated NFSv3 header directly in nfsfh.c and nfsctl.c. - Remove the unused struct nfsd3_createargs in the MKDIR patch. - Regenerate the READDIR and READDIRPLUS result decoders. - Drop the decode-hook stubs the regenerated decoders no longer call. - Link to v1: https://lore.kernel.org/linux-nfs/20260923132811.244160-1-cel@kernel.org/ 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 NFSD: Replace the nfsd3_createres macro NFSD: Relocate the NFSv3 XDR storage union into nfs3proc.c NFSD: Use xdrgen XDR functions for the NFSv3 NULL procedure NFSD: Use xdrgen XDR functions for NFSv3 GETATTR procedure NFSD: Use xdrgen XDR functions for NFSv3 SETATTR procedure NFSD: Use xdrgen XDR functions for the NFSv3 LOOKUP procedure NFSD: Use xdrgen XDR functions for NFSv3 ACCESS procedure NFSD: Use xdrgen XDR functions for NFSv3 READLINK procedure NFSD: Use xdrgen XDR functions for NFSv3 READ procedure NFSD: Use xdrgen XDR functions for NFSv3 WRITE procedure NFSD: Use xdrgen XDR functions for NFSv3 CREATE procedure NFSD: Use xdrgen XDR functions for NFSv3 MKDIR procedure NFSD: Use xdrgen XDR functions for NFSv3 SYMLINK procedure NFSD: Use xdrgen XDR functions for NFSv3 MKNOD procedure NFSD: Use xdrgen XDR functions for the NFSv3 REMOVE procedure NFSD: Use xdrgen XDR functions for the NFSv3 RMDIR procedure NFSD: Use xdrgen XDR functions for the NFSv3 RENAME procedure NFSD: Use xdrgen XDR functions for the NFSv3 LINK procedure NFSD: Use xdrgen XDR functions for the NFSv3 FSSTAT procedure NFSD: Use xdrgen XDR functions for the NFSv3 FSINFO procedure NFSD: Use xdrgen XDR functions for the NFSv3 PATHCONF procedure NFSD: Use xdrgen XDR functions for the NFSv3 COMMIT procedure NFSD: Use xdrgen XDR functions for NFSv3 READDIR arguments NFSD: Use xdrgen XDR functions for NFSv3 READDIRPLUS arguments NFSD: Refactor NFSv3 directory cookie encoding NFSD: Refactor NFSv3 directory entry encoding NFSD: Split struct nfsd3_readdirres NFSD: Use xdrgen XDR functions for NFSv3 READDIR results NFSD: Use xdrgen XDR functions for NFSv3 READDIRPLUS results Documentation/sunrpc/xdr/nfs3.x | 839 ++++++ fs/nfsd/Makefile | 15 +- fs/nfsd/nfs2acl.c | 41 +- fs/nfsd/nfs3acl.c | 12 +- fs/nfsd/nfs3proc.c | 2545 +++++++++++++------ fs/nfsd/nfs3xdr.c | 1369 +++------- fs/nfsd/nfs3xdr_gen.c | 3808 ++++++++++++++++++++++++++++ fs/nfsd/nfs3xdr_gen.h | 82 + fs/nfsd/nfsctl.c | 2 +- fs/nfsd/nfserr.h | 2 +- fs/nfsd/nfsfh.c | 2 +- fs/nfsd/vfs.c | 76 +- fs/nfsd/xdr3.h | 300 +-- include/linux/nfs3.h | 3 - include/linux/sunrpc/xdrgen/nfs3.h | 1092 ++++++++ 15 files changed, 8021 insertions(+), 2167 deletions(-) create mode 100644 Documentation/sunrpc/xdr/nfs3.x create mode 100644 fs/nfsd/nfs3xdr_gen.c create mode 100644 fs/nfsd/nfs3xdr_gen.h create mode 100644 include/linux/sunrpc/xdrgen/nfs3.h base-commit: 21c66e2ece97c0ac8139b44051d565b29574f821 -- 2.55.0
