In order to generate source code to encode and decode NLMv3 protocol elements, include a copy of the RPC language description of NLMv3 for xdrgen to process. The language description is derived from the Open Group's XNFS specification: https://pubs.opengroup.org/onlinepubs/9629799/chap10.htm#tagcjh_11_03 The C code committed here was generated from the new nlm3.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. Parts of the NFSv4 protocol are still being extended actively. Tool-generated XDR code reduces the time it takes to get a working implementation of new protocol elements. 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.
