Mastering Linux Kernel Development

By: CH Raghav Maruthi

Overview of this book

Mastering Linux Kernel Development looks at the Linux kernel, its internal arrangement and design, and various core subsystems, helping you to gain significant understanding of this open source marvel. You will look at how the Linux kernel, which possesses a kind of collective intelligence thanks to its scores of contributors, remains so elegant owing to its great design. This book also looks at all the key kernel code, core data structures, functions, and macros, giving you a comprehensive foundation of the implementation details of the kernel’s core services and mechanisms. You will also look at the Linux kernel as well-designed software, which gives us insights into software design in general that are easily scalable yet fundamentally strong and safe. By the end of this book, you will have considerable understanding of and appreciation for the Linux kernel.

Chapter 1. Comprehending Processes, Address Space, and Threads

When kernel services are invoked in the current process context, its layout throws open the right path for exploring kernels in more detail. Our effort in this chapter is centered around comprehending processes and the underlying ecosystem the kernel provides for them. We will explore the following concepts in this chapter:

  • Program to process
  • Process layout
  • Virtual address spaces
  • Kernel and user space
  • Process APIs
  • Process descriptors
  • Kernel stack management
  • Threads
  • Linux thread API
  • Data structures
  • Namespace and cgroups
