Linux Kernel Module in Rust

Old introduction: See old readme.

System requirements

• kernel version: 6.6 or 6.8

Building hello-world

1. Install clang, kernel headers, and the rust-src and rustfmt components from rustup:

apt-get install llvm clang linux-headers-"$(uname -r)" # or the equivalent for your OS
rustup component add --toolchain=nightly rust-src rustfmt

2. cd to one of the examples

cd tests/hello-world

3. Build the kernel module using the Linux kernel build system (kbuild), this will invoke cargo to build the Rust code

make

4. Load and unload the module!

sudo insmod helloworld.ko
sudo rmmod helloworld
dmesg | tail
