Linux Systems Programming with C: Build High-Performance, Secure, and Scalable Software for Kernel, Drivers, and Cybersecurity Applications How do you write code that speaks directly to the Linux kernel, code that runs fast, scales effortlessly, and resists failure under the harshest conditions? Linux Systems Programming with C: Build High-Performance, Secure, and Scalable Software for Kernel, Drivers, and Cybersecurity Applications gives you that mastery.
This book is a comprehensive guide for professional software developers, systems engineers, and cybersecurity practitioners who want to go beyond application-level programming and work at the very heart of Linux. It focuses on the real-world skills that make modern systems resilient, observable, and efficient, from compiler-level optimizations to runtime sandboxing and kernel-space integration.
Through practical, production-ready examples and thoroughly tested lab exercises, you'll learn how to:
- Build, configure, and harden C toolchains with GCC, Clang, and modern linkers such as mold and LLD.
- Write secure, memory-safe system components using sanitizers, defensive idioms, and controlled memory allocators.
- Implement asynchronous I/O and high-throughput networking with io_uring, epoll, and multishot submissions.
- Develop and load shared libraries, plugins, and kernel-interfacing code using ELF fundamentals and version scripts.
- Integrate observability with perf, ftrace, and eBPF for real-time profiling, debugging, and tracing.
- Enforce runtime security with Landlock, seccomp, namespaces, and openat2-based path hardening.
- Package, test, and benchmark Linux services with reproducible builds, LTO optimization, and CI-driven fuzzing.
Unlike most system programming texts, this book doesn't stop at theory, it gives you reproducible builds, fully runnable code, and context-rich explanations that mirror the workflows used by modern infrastructure teams. You'll learn not just what each API does, but why it matters, how it interacts with the kernel boundary, and how to use it safely in concurrent and high-load environments. Whether you're building drivers, optimizing daemons, or securing firmware, this book will teach you how to think like a systems architect. You'll see how to connect compiler flags to runtime performance, observability tools to debugging, and kernel interfaces to real-world reliability.
If your goal is to write Linux software that lasts, software that's fast, stable, and secure, this is where your next level begins. Get your copy today and start building systems that stand the test of time.
