As in earlier Addison-Wesley books on the UNIX-based BSD operating system, Kirk McKusick and George Neville-Neil deliver here the most comprehensive, up-to-date, and authoritative technical information on the internal structure of open source FreeBSD. Readers involved in technical and sales support can learn the capabilities and limitations of the system; applications developers can learn effectively and efficiently how to interface to the system; system administrators can learn how to maintain, tune, and configure the system; and systems programmers can learn how to extend, enhance, and interface to the system. The authors provide a concise overview of FreeBSD's design and implementation. Then, while explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing the systems facilities. As a result, readers can use this book as both a practical reference and an in-depth study of a contemporary, portable, open source operating system. This book: * Details the many performance improvements in the virtual memory system * Describes the new symmetric multiprocessor support * Includes new sections on threads and their scheduling * Introduces the new jail facility to ease the hosting of multiple domains * Updates information on networking and interprocess communication Already widely used for Internet services and firewalls, high-availability servers, and general timesharing systems, the lean quality of FreeBSD also suits the growing area of embedded systems. Unlike Linux, FreeBSD does not require users to publicize any changes they make to the source code.

Über den Autor
Marshall Kirk McKusick writes books and articles, consults, and teaches classes on UNIX- and BSD-related subjects. While at the University of California at Berkeley, he implemented the 4.2BSD fast file system, and was the research computer scientist at the Berkeley Computer Systems Research Group (CSRG) overseeing the development and release of 4.3BSD and 4.4BSD. He has twice served as the president of the board of the Usenix Association. George V. Neville-Neil works on network and operating system code for fun and profit and teaches programming. He also serves on the editorial board of Queue magazine and is a member of the Usenix Association, ACM, and IEEE.

More or less, "Design and Implementation of the FreeBSD Operating System" is the third edition of the successful "Design and Implementation of the 4.3/4.4BSD Operating System", dating from 1991 and 1996, respectively. The authors did a great job updating the existing material to the state of the art, thereby taking care of the shift in importance of certain topics (e.g. more networking, less character-terminal handling). Stuff not existing in 4.4BSD, like layered device driver approaches for block devices and the FreeBSD "jail" functionality, is explained thoroughly - you can see that the authors spents significant time working on the code itself (McKusick was a member of the original OS research group at Berkeley) and analyzing the developments of the last 8 years.
A bit of additional information on SMP and related concepts would have been great, but nevertheless this book is a must for any programmer and kernel hacker who wants to know what's going on under the hood of a modern Unix-like operating system.

This is my definitve guide how a UNIX system and especially FreeBSD works in general.
It doesn't just give you a broad overview of the FreeBSD kernel, but also explains every kernel concept in detail, like virtual memory (shadow objects, private and public memory areas ...) and filesystems (filesystem stacking, soft updates and fsck in the background).
After reading this book you can go right ahead and read the kernel source by yourself, since every important function is explained, sometimes even in pseudo code.
You should be already familiar with basic operating system and computer architecture concepts, though, like virtual memory(MMU, paging), scheduling (semaphores, multilevel feedback queues), network protocols (TCP/IP) and I/O(buses, DMA)
Virtual memory and filesystems are covered in great detail, due to the fact that Kirk himself wrote these two subsystems.

This book is a must read for every FreeBSD kernel fan. The book gives detailed knowledge about all relevant subsystems of the kernel (processes, memory management, file systems, networking, ...).
Especially the chapter about the BSD Fast File System with Soft Updates is very detailed and informative. McKusick is one of the authors of the FFS and the Soft Updates Code in the kernel.
