Rust for Linux Programming
Build kernel modules, drivers, file systems, networking, and memory using Rust's ownership, traits, and RAII
This book is 100% completeLast updated on 2026-06-17
I wrote this book to show exactly what happens when you add Rust to the kernel. Not as a toy. Not as a single driver in a conference demo. It's a full module that covers process management, memory allocation, file systems, networking, device drivers, inter-process communication, and even machine learning inference. It's all built on safe abstractions, all compiled into one loadable binary, all tested on a running kernel. You'll find that each chapter adds new source files to the same module.

About the Book
What's really cool is this hands-on Rust book takes you inside the Linux kernel and gives you the power to reshape it. It's all about building working kernel subsystems from scratch, covering process management, memory allocation, virtual file systems, networking, device drivers, inter-process communication, and AI-powered inference, and all in Rust. When you're done, you'll have registered procfs and sysfs interfaces, written Netfilter hooks that classify packets with a neural network, constructed RAII wrappers for DMA buffers and interrupt handlers, and implemented a complete in-memory file system on the VFS layer.
Each chapter adds new source files to the same module, so by the time you get to the last chapter, your codebase has grown to various kernel subsystems. This hands-on, trainer-led approach is designed for both those new to Rust and experienced Rust developers looking to get into kernel space. You'll get the skills, patterns and confidence to write top-notch kernel code that's just as fast and safe as its C equivalent.
Key Learnings
- Build and load kernel modules using Rust-for-Linux toolchain
- Wrap unsafe C kernel APIs into safe RAII abstractions
- Manage kernel memory through page allocation, slab caches, and memory pools

About the Author
GitforGits | Asian Publishing House
We are the engineer’s publisher, the coder’s mentor, and the content alchemist—meticulously turning dense tech into practical gold. With a growing library of 100+ titles, we don’t just develop technical books, rather we build roadmaps for professionals across Python, MySQL, DevOps, Rust, AI, Kotlin, Arduino, Golang and everything around the massive IT ecosystem. Every chapter, every script, every project is a tool in the hands of developers who want to get things done.
Where others summarize, we construct step-by-step learning blueprints, cutting through clutter, banning the fluff, and ensuring every paragraph delivers hands-on value. Our audience isn’t learning from scratch—they’re leveling up with purpose, and we stand by them with code-first content, consistent project workflows, and a zero-redundancy approach.
Earn $8 on a $10 Purchase, and $16 on a $20 Purchase
We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.
