Saving and Restoring Processes with CRIU: The Challenge of Shadow Stacks on ARM64

This talk introduces CRIU, the tool behind process checkpoint/restore and container live migration, and explores what happens when future CPU features meet current software.

Igor shares his work extending CRIU to support the upcoming Arm64 Guarded Control Stack (GCS), explaining why it breaks existing restore logic, how he made it work, and what he learned by digging into process state, signal frames, and other OS mechanisms CRIU leverages.
