Linux Internals Supplements

The book contains the full transcript of Software Diagnostics Services training. Learn disassembly, execution history reconstruction, and binary reversing techniques for better software diagnostics, troubleshooting, debugging, memory forensics, vulnerability, and malware analysis on x64 (x86_64) and A64 (ARM64, AArch64) Linux platforms. The course uses a unique and innovative pattern language approach to speed up the learning curve. The training consists of practical step-by-step, hands-on exercises using GDB and Linux core memory dumps. Covered more than 25 ADDR patterns originally introduced for the x64 Windows platform, and many concepts are illustrated with Memory Cell Diagrams. The prerequisites for this training are a working knowledge of C and C++ programming languages. Operating system internals and assembly language concepts are explained when necessary. The primary audience for this training is software technical support and escalation engineers who analyze memory dumps from complex software environments and need to go deeper in their analysis of abnormal software structure and behavior. The course is also useful for software engineers, quality assurance, and software maintenance engineers who debug software running on diverse cloud and endpoint computer environments, SRE and DevSecOps, security and vulnerability researchers, and malware and memory forensics analysts who have never used GDB for analysis of computer memory. The book also features ADDR pattern descriptions summarized after each exercise. The second edition includes a review of relevant assembly language fundamentals and relevant differences between GCC and Clang.
