Control Flow Integrity on RISC-V

Explore the critical topic of Control Flow Integrity (CFI) on RISC-V architecture in this 20-minute conference talk from the Linux Plumbers Conference. Delve into the implications of memory safety issues on program integrity and learn about various software and hardware mechanisms for enforcing CFI. Examine the ongoing efforts to ratify a CFI extension for RISC-V and discuss the approach and design decisions surrounding the CFI patch series. Gain insights into leveraging the CFI extension to enhance kernel control flow integrity on RISC-V systems. Understand the importance of shadow stacks and landing pad instructions in maintaining program safety and discover how mainstream instruction set architectures are addressing these concerns.
