summary

A walkthrough of investigating and fixing a six-year-old Linux kernel network bug: the talk explains how the presenters discovered the issue, performed troubleshooting and diagnosis inside the Linux kernel codebase, implemented a minimal two-line fix, and submitted that patch to the kernel community. It emphasizes practical steps and learning-from-zero so attendees without prior kernel experience can follow the debugging, patching, and contribution process.
