KFLAT - Selective Kernel Memory Serialization for Security and Debugging

Explore a novel tool for fine-grained Linux kernel memory serialization in this 48-minute conference talk by Bartosz Zator and Paweł Wieczorek from Samsung Poland Research Institute. Learn about KFLAT, a tool that allows selective copying of kernel memory for specific variables and structures, enabling efficient debugging and testing. Discover how KFLAT produces flattened memory images for quick loading and high test throughput. Compare KFLAT with other Linux memory serialization tools and understand its benefits for kernel testing and debugging processes. Delve into implementation details, interesting problems, and solutions. Examine how KFLAT serves as the foundation for state initialization in the Auto Off-Target (AoT) project and its application in fuzzing Linux kernel entry points in userspace.
