GWP-ASan: Sampling-Based Detection of Memory-Safety Bugs in Production
This paper describes a family of tools that detect these two classes of memory-safety bugs, while running in production, at near-zero overhead. These tools combine page-granular guarded allocation and low-rate sampling. In other words, we added an “if” statement to a 36-year-old idea and made it work at scale
