In order to generate source code to encode and decode NLMv4 protocol elements, include a copy of the RPC language description of NLMv4 for xdrgen to process. The language description is an amalgam of RFC 1813 and the Open Group's XNFS specification: https://pubs.opengroup.org/onlinepubs/9629799/chap10.htm The C code committed here was generated from the new nlm4.x file using tools/net/sunrpc/xdrgen/xdrgen. The goals of replacing hand-written XDR functions with ones that are tool-generated are to improve memory safety and make XDR encoding and decoding less brittle to maintain. The xdrgen utility derives both the type definitions and the encode/decode functions directly from protocol specifications, using names and symbols familiar to anyone who knows those specs. Unlike hand-written code that can inadvertently diverge from the specification, xdrgen guarantees that the generated code matches the specification exactly. We would eventually like xdrgen to generate Rust code as well, making the conversion of the kernel's NFS stacks to use Rust just a little easier for us.
