Driving Safety Forward: Lessons Learned From Deploying OSS in Real-world Automotive
Talkat Open Source Summit Japan + AI_dev: Open Source GenAI & ML Summit + Automotive Linux Summit 2025 · 2025-12-08..12-10·
summary
Shares a production story of shipping EMQ-based stacks into mass-market cars, using multi-party fuzzing and academic toolchains to find concurrency bugs in nanoMQ and broker code, then recording and replaying message flows to make nondeterministic crashes reproducible. Describes an OEM failure caused by MQTT/Paho misuse that exhausts file descriptors, triggers an STR (suspend-to-RAM) bug, and drains batteries, and explains fixes: end-to-end open source stack, buffering/prioritization, improved observability, time sync and filesystem tuning — deployed and effective in the field.
