Explore advanced debugging techniques for third-party C++ code in Free Range Routing (FRR), a widely used open source routing protocol software for building networking applications and Network Operating Systems (NOS). Learn to perform root cause analysis of complex routing protocol bugs using Undo's UDB time travel debugging tool, focusing on real-world scalability issues and performance problems affecting static routes. Discover how to analyze software performance in networking environments through practical demonstrations of debugging embedded systems and routing software implementations. Master the use of developer tools including flame graphs to pinpoint performance bottlenecks and identify root causes of software bugs in complex networking stacks. Gain insights into effective troubleshooting methodologies for C++ routing protocol implementations, covering topics from initial problem identification through final bug resolution. Understand how time travel debugging revolutionizes the debugging process by allowing you to step backwards through code execution to trace the exact sequence of events leading to software failures. Apply these debugging techniques to improve software reliability in Linux environments while developing practical skills in performance analysis and root cause investigation for both software engineering and network engineering applications.
