Session
This talk presents a behavior-based fault injection approach for OpenBMC firmware. By injecting faults at the I/O layer and using real-world failure models, we enhance grey-box testing coverage without modifying code or restarting services. Leveraging tools like Frida and eBPF, our method enables efficient, interpretable, and cross-environment validation of BMC robustness.
