Uses the Running Operation as the Main Thread Difficulty in understanding an operating system (OS) lies not in the technical aspects, but in the complex relationships inside the operating systems. The Art of Linux Kernel Design: Illustrating the Operating System Design Principle and Implementation addresses this complexity. Written from the perspective of the designer of an operating system, this book tackles important issues and practical problems on how to understand an operating system completely and systematically. It removes the mystery, revealing operating system design guidelines, explaining the BIOS code directly related to the operating system, and simplifying the relationships and guiding ideology behind it all. Based on the Source Code of a Real Multi-Process Operating System Using the 0.11 edition source code as a representation of the Linux basic design, the book illustrates the real states of an operating system in actual operations. It provides a complete, systematic analysis of the operating system source code, as well as a direct and complete understanding of the real operating system run-time structure. The author includes run-time memory structure diagrams, and an accompanying essay to help readers grasp the dynamics behind Linux and similar software systems. Identifies through diagrams the location of the key operating system data structures that lie in the memory Indicates through diagrams the current operating status information which helps users understand the interrupt state, and left time slice of processes Examines the relationship between process and memory, memory and file, file and process, and the kernel Explores the essential association, preparation, and transition, which is the vital part of operating system Develop a System of Your Own This text offers an in-dep

MicroC/OS II Second Edition describes the design and implementation of the MicroC/OS-II real-time operating system (RTOS). In addition to its value as a reference to the kernel, it is an extremely detailed and highly readable design study particularly useful to the embedded systems student. While documenting the design and implementation of the kernel, the book also walks the reader through the many related development issues: how to adapt the kernel for a new microprocessor, how to install the kernel, and how to structure the applications that run on the kernel. This edition features documentation for several important new features of the software, including new real-time services, floating points, and coding conventions. The accompanying CDROM includes complete code for the MicroC/OS-II kernel.

A Guide to Kernel Exploitation: Attacking the Core discusses the theoretical techniques and approaches needed to develop reliable and effective kernel-level exploits, and applies them to different operating systems, namely, UNIX derivatives, Mac OS X, and Windows. Concepts and tactics are presented categorically so that even when a specifically detailed vulnerability has been patched, the foundational information provided will help hackers in writing a newer, better attack; or help pen testers, auditors, and the like develop a more concrete design and defensive structure. The book is organized into four parts. Part I introduces the kernel and sets out the theoretical basis on which to build the rest of the book. Part II focuses on different operating systems and describes exploits for them that target various bug classes. Part III on remote kernel exploitation analyzes the effects of the remote scenario and presents new techniques to target remote issues. It includes a step-by-step analysis of the development of a reliable, one-shot, remote exploit for a real vulnerabilitya bug affecting the SCTP subsystem found in the Linux kernel. Finally, Part IV wraps up the analysis on kernel exploitation and looks at what the future may hold.Covers a range of operating system families ― UNIX derivatives, Mac OS X, WindowsDetails common scenarios such as generic memory corruption (stack overflow, heap overflow, etc.) issues, logical bugs and race conditionsDelivers the reader from user-land exploitation to the world of kernel-land (OS) exploits/attacks, with a particular focus on the steps that lead to the creation of successful techniques, in order to give to the reader something more than just a set of tricks

This book explains the design and implementation of C/OS [pronounced "MicroC/OS"], the Micro-Controller Operating System, a portable, ROMable, preemptive, real-time, multitasking kernel for microprocessors. The system is written in C with assembly language code for the target microprocessor kept to a minimum. It can be ported to any microprocessor that provides a stack pointer and allows the CPU registers to be pushed onto and popped from the stack. The C compiler must be ANSI compatible and provide in-line assembly or language extensions that allow you to enable and disable interrupts. The system can manage up to 63 tasks, with performance comparable to many commercially available kernels. An earlier version of C/OS was published in the May and June 1992 issues of Embedded Systems Programming magazine. The code available from that article on bulletin board systems is uncommented. The code provided in "C/OS" the book is fully commented. The current release of the companion code disk V 1.08 has been updated in response to reader response. See the author's Release Notes for more information on revisions to the code. The text explains the fundamentals of multitasking real-time systems, details the design decisions of this kernel, and includes a user's manual for the system. Appendices provide complete code for the system, a port for the Intel 80186/80188 chip, a survey of real-time kernel manufacturers, and references to the technical literature on real-time and embedded systems. Source code is provided, so you can add your own custom features. Integrating C/OS in your application can be done in less than one day. C/OS can be ported to a different microprocessor within a few days, because assembly code has been kept to a minimum. Audience: To use the book, you should be familiar with the ANSI standard for C, and have at least a minimum understanding of assembly language for the Intel 80x86 family of microprccessors.

Though rootkits have a fairly negative image, they can be used for both good and evil. Designing BSD Rootkits arms you with the knowledge you need to write offensive rootkits, to defend against malicious ones, and to explore the FreeBSD kernel and operating system in the process.Organized as a tutorial, Designing BSD Rootkits will teach you the fundamentals of programming and developing rootkits under the FreeBSD operating system. Author Joseph Kong's goal is to make you smarter, not to teach you how to write exploits or launch attacks. You'll learn how to maintain root access long after gaining access to a computer and how to hack FreeBSD.Kongs liberal use of examples assumes no prior kernel-hacking experience but doesn't water down the information. All code is thoroughly described and analyzed, and each chapter contains at least one real-world application.Included:The fundamentals of FreeBSD kernel module programmingUsing call hooking to subvert the FreeBSD kernelDirectly manipulating the objects the kernel depends upon for its internal record-keepingPatching kernel code resident in main memory; in other words, altering the kernel's logic while it's still runningHow to defend against the attacks describedHack the FreeBSD kernel for yourself!

Analyzing how hacks are done, so as to stop them in the future Reverse engineering is the process of analyzing hardware or software and understanding it, without having access to the source code or design documents. Hackers are able to reverse engineer systems and exploit what they find with scary results. Now the good guys can use the same tools to thwart these threats. Practical Reverse Engineering goes under the hood of reverse engineering for security analysts, security engineers, and system programmers, so they can learn how to use these same processes to stop hackers in their tracks. The book covers x86, x64, and ARM (the first book to cover all three); Windows kernel-mode code rootkits and drivers; virtual machine protection techniques; and much more.
