Building the Fedora Linux Kernel with Rust Support

I've been using Fedora Linux for a couple years now, and this week I wanted to write a kernel module for some reasons. Of course, I try to write all software I possibly can in Rust, and Linux recently has support for writing modules, including out of tree modules, in Rust! Great, so it should be really easy, just copy the rust-out-of-tree-module Makefile and Kbuild, run make, and

Note 1

Your Config.in file...it needs to have a newline after endmenu, if you have menu. So basically:

menu "Kernel Modules"
    source "$BR2_EXTERNAL_TEST_KERNEL_MODULES_PATH/package/kernel-modules/test-mod/Config.in"
endmenu

I used to have a site bookmarked with a table of all these functions, but the link is dead. Here's a matrix of Option and Result conversion functions. These become second nature once you have used Rust for any significant length of time, but it's useful to have a table reference.

For each of the below:

• T is the value possibly contained in an input Ok Result or Some Option.
• U is a new value created by transforming or replacing an input T. Note that when U appears in methods like map, U ?= T, for example by calling

Rust's expected/produced library naming

What rustc/your linker expects

Rust handles libraries that it links with in a somewhat "magical" way, in that if you want to link to libpixman-1.so.0 you would just write:

println!("cargo:rustc-link-lib=pixman-1");

RPATH vs RUNPATH

I'm doing some ELF parsing and I need to simulate ld.so's lookup routine (man ld.so). To do that, I need to grab RPATH as well as RUNPATH from binaries, so to test my tool I naturally need to make some binaries with each of those. Here's how you do it.

cat <<EOF > /tmp/a.c
int main(){}
EOF
