Get up and running with system programming concepts in Linux Key Features Acquire insight on Linux system architecture and its programming interfaces Get to grips with core concepts such as process management, signalling and pthreads Packed with industry best practices and dozens of code examples Book DescriptionThe Linux OS and its embedded and server applications are critical components of today’s software infrastructure in a decentralized, networked universe. The industry's demand for proficient Linux developers is only rising with time. Hands-On System Programming with Linux gives you a solid theoretical base and practical industry-relevant descriptions, and covers the Linux system programming domain. It delves into the art and science of Linux application programming— system architecture, process memory and management, signaling, timers, pthreads, and file IO. This book goes beyond the use API X to do Y approach; it explains the concepts and theories required to understand programming interfaces and design decisions, the tradeoffs made by experienced developers when using them, and the rationale behind them. Troubleshooting tips and techniques are included in the concluding chapter. By the end of this book, you will have gained essential conceptual design knowledge and hands-on experience working with Linux system programming interfaces.What you will learn Explore the theoretical underpinnings of Linux system architecture Understand why modern OSes use virtual memory and dynamic memory APIs Get to grips with dynamic memory issues and effectively debug them Learn key concepts and powerful system APIs related to process management Effectively perform file IO and use signaling and timers Deeply understand multithreading concepts, pthreads APIs, synchronization and scheduling Who this book is for Hands-On System Programming with Linux is for Linux system engineers, programmers, or anyone who wants to go beyond using an API set to understanding the theoretical underpinnings and concepts behind powerful Linux system programming APIs. To get the most out of this book, you should be familiar with Linux at the user-level logging in, using shell via the command line interface, the ability to use tools such as find, grep, and sort. Working knowledge of the C programming language is required. No prior experience with Linux systems programming is assumed.
System Programming in Linux

Learn to write real Linux software—not just run it. Most programmers never learn how Linux really works. Why? Because system programming is rarely taught, and the tools can be intimidating without the right guidance. As a result, many developers stick to high-level languages and frameworks—writing code that runs on Linux without understanding how it interacts with Linux. In today’s world, that’s not enough to stand out. Especially as more companies turn to AI to write their software, the question becomes: How do you stay relevant in an AI-driven world? You learn how things really work. If you’ve ever wondered how processes are created, how memory and files are managed, or how programs communicate in a Unix environment, System Programming in Linux will make it all make sense. This is a hands-on guide to writing software that interfaces directly with the Linux operating system. You’ll go beyond shell commands and abstractions to understand what the kernel is doing—and how to leverage it through your own code. Rather than telling you how to solve each problem, Professor Stewart N. Weiss guides you through the process of discovering the solution yourself. Start with the core concepts of Unix and Linux, then work your way up to advanced topics like process control, signals, interprocess communication, threading, and non-blocking I/O. Each chapter includes conceptual diagrams, annotated source code, and practical projects to help you immediately apply what you’ve learned. You’ll explore topics such as: The structure of Unix and Linux operating systems—and why it matters Using system calls to create and manage processes The mechanics of signals, timers, and interprocess communication Using synchronization tools to write multithreaded programs Interacting with filesystems, devices, and terminals Building text-based user interfaces using ncurses Developing programs that are robust, efficient, and portable At Hunter College, Professor Weiss built the course this book is based on, and he has helped thousands of students go from confusion to confidence in his over 40 years of teaching programming. His clear, conversational style; technical depth; and focus on real-world application make this one of the most approachable and powerful system programming books available. As Linux continues to dominate development, server, and embedded environments, understanding the system behind your software isn’t just helpful; it’s essential. Whether you’re a student, developer, or sysadmin, this book gives you the tools to work directly with Linux and the insight to understand what’s really happening under the hood.

Learn how to write high-quality kernel module code, solve common Linux kernel programming issues, and understand the fundamentals of Linux kernel internals Key Features Discover how to write kernel code using the Loadable Kernel Module framework Explore industry-grade techniques to perform efficient memory allocation and data synchronization within the kernel Understand the essentials of key internals topics such as kernel architecture, memory management, CPU scheduling, and kernel synchronization Book DescriptionLinux Kernel Programming is a comprehensive introduction for those new to Linux kernel and module development. This easy-to-follow guide will have you up and running with writing kernel code in next-to-no time. This book uses the latest 5.4 Long-Term Support (LTS) Linux kernel, which will be maintained from November 2019 through to December 2025. By working with the 5.4 LTS kernel throughout the book, you can be confident that your knowledge will continue to be valid for years to come. You’ll start the journey by learning how to build the kernel from the source. Next, you’ll write your first kernel module using the powerful Loadable Kernel Module (LKM) framework. The following chapters will cover key kernel internals topics including Linux kernel architecture, memory management, and CPU scheduling. During the course of this book, you’ll delve into the fairly complex topic of concurrency within the kernel, understand the issues it can cause, and learn how they can be addressed with various locking technologies (mutexes, spinlocks, atomic, and refcount operators). You’ll also benefit from more advanced material on cache effects, a primer on lock-free techniques within the kernel, deadlock avoidance (with lockdep), and kernel lock debugging techniques. By the end of this kernel book, you’ll have a detailed understanding of the fundamentals of writing Linux kernel module code for real-world projects and products.What you will learn Write high-quality modular kernel code (LKM framework) for 5.x kernels Configure and build a kernel from source Explore the Linux kernel architecture Get to grips with key internals regarding memory management within the kernel Understand and work with various dynamic kernel memory alloc/dealloc APIs Discover key internals aspects regarding CPU scheduling within the kernel Gain an understanding of kernel concurrency issues Find out how to work with key kernel synchronization primitives Who this book is for This book is for Linux programmers beginning to find their way with Linux kernel development. If you’re a Linux kernel and driver developer looking to overcome frequent and common kernel development issues, or understand kernel intervals, you’ll find plenty of useful information. You’ll need a solid foundation of Linux CLI and C programming before you can jump in.
