RADSan: A Realtime-Safety Sanitizer - David Trevelyan & Ali Barker - ADC23
"ERROR: RealtimeSanitizer: call to malloc detected during execution of realtime function SketchyAlgorithm::process!"
We present RADSan, a realtime-safety sanitizer integrated into the LLVM project. Activated with a single argument to clang, RADSan allows developers to mark any function with a [[realtime]] attribute. At run time, realtime functions will error if RADSan detects activity that it knows is not realtime-safe.
Our talk will include:
• an introduction to sanitizers; what they do and how they work,
• an exploration of the realtime-safety testing problem space; what is (and what isn't) possible, and how this influenced RADSan's design,
• a deep-dive into the components of RADSan and how they work together
• a demonstration of how to use RADSan to mark functions as realtime and test a system's realtime safety
• an open discussion on how to best share this idea with the wider community
