The Linux kernel stands as the foundational component of modern computing infrastructure. It powers the vast majority of servers in data centers, cloud platforms operated by major providers, embedded systems in Internet of Things devices, smartphones through Android, and even the world's most powerful supercomputers. As the core of Linux-based operating systems, the kernel manages hardware resources, facilitates communication between software and physical components, and ensures secure and efficient execution of user applications. Understanding its internal workings distinguishes proficient system users from genuine experts capable of diagnosing complex issues, optimizing performance under heavy loads, and developing extensions that integrate seamlessly with the operating system.This book targets software engineers, system programmers, DevOps professionals, and operating system enthusiasts who seek practical, in-depth mastery of Linux internals. Rather than presenting abstract theoretical discussions in isolation, the content emphasizes applied knowledge through real-world scenarios, detailed step-by-step workflows, annotated code examples in the C programming language, and hands-on exercises using essential debugging and profiling tools. Readers will explore kernel architecture, process and memory management, filesystem operations, device driver development, networking internals, performance tuning, advanced debugging techniques, and security hardening strategies. By engaging with these topics, professionals gain the ability to troubleshoot production environments effectively, write reliable kernel modules, analyze system bottlenecks, and implement optimizations that scale to enterprise demands.
