Mastering Linux Kernel Programming: From Kernel Architecture and Device Drivers to eBPF and Rust for Systems Engineers
The Gap Between Good Developers and Kernel Engineers Is Smaller Than You Think
Most engineers spend their careers one layer above the code that actually matters. They build on top of the kernel, debug issues that originate inside it, and hit performance limits they cannot fully explain - because the real decisions are hidden in scheduling, memory allocation, and driver behavior they have never seen.
It does not have to be that way.
Mastering Linux Kernel Programming is a production-focused guide to understanding how the Linux kernel actually works - and how to build inside it. You will go from core architecture and mental models to real-world implementation: device drivers, memory management, concurrency, eBPF observability, Rust in the kernel, and network driver development.
Every chapter is built around working code, real subsystems, and the same patterns used by professional kernel engineers.
This is not a survey. This is a complete engineering path.
What You'll LearnBuild production-quality kernel modules, drivers, and subsystems
Master memory management, from page allocation to DMA
Write correct concurrent kernel code using locks, RCU, and memory barriers
Develop eBPF programs with libbpf and CO-RE for observability and security
Use Rust in the kernel for memory-safe systems programming
Implement high-performance network drivers with NAPI and full stack integration
Validate and prepare code for upstream Linux kernel submission
Who This Book Is ForThis book is for engineers ready to go deeper:
Systems programmers who want to understand what happens below userspace
Embedded engineers building drivers and platform integrations
DevOps and SREs diagnosing performance and production issues
Security engineers working on kernel-level tooling and analysis
Software engineers transitioning into systems and infrastructure roles
You should be comfortable with C and familiar with Linux. No prior kernel experience is required.
Why This Book Is Different
Most kernel books are outdated or stop at toy examples.
This book is built for Linux 6.x and modern production systems:
Uses libbpf and CO-RE, not legacy tooling
Covers in-tree Rust kernel development (Linux 6.1+)
Implements real subsystems, not "hello world" modules
Walks through building and submitting a complete kernel patch series
You don't just learn concepts - you build working systems.
What You Get
Fully working code and QEMU-based development environment
Architecture diagrams and decision guides for real engineering choices
Practical exercises in every chapter
Reference appendices for tools, workflows, and kernel development
Where This Leads
The Linux kernel is one of the most critical systems in modern computing - and one of the least understood.
Engineers who can work at this level are rare.
This book takes you from understanding the kernel to contributing to it - with a complete capstone subsystem, validated tooling, and a clear path into the Linux kernel community.
