2026-01-26	xdrgen: Fix struct prefix for typedef types in program wrappers	Chuck Lever
	The program templates for decoder/argument.j2 and encoder/result.j2 unconditionally add 'struct' prefix to all types. This is incorrect when an RPC protocol specification lists a typedef'd basic type or an enum as a procedure argument or result (e.g., NFSv2's fhandle or stat), resulting in compiler errors when building generated C code.

2024-09-20	tools: Add xdrgen	Chuck Lever
	Add a Python-based tool for translating XDR specifications into XDR encoder and decoder functions written in the Linux kernel's C coding style. The generator attempts to match the usual C coding style of the Linux kernel's SunRPC consumers. This approach is similar to the netlink code generator in tools/net/ynl . The maintainability benefits of machine-generated XDR code include: - Stronger type checking - Reduces the number of bugs introduced by human error - Makes the XDR code easier to audit and analyze - Enables rapid prototyping of new RPC-based protocols - Hardens the layering between protocol logic and marshaling - Makes it easier to add observability on demand - Unit tests might be built for both the tool and (automatically) for the generated code In addition, converting the XDR layer to use memory-safe languages such as Rust will be easier if much of the code can be converted automatically.
