Improving fuzzing coverage and fixing bugs
OSS-Fuzz is now reporting 99.5% function coverage and ~94% region coverage. Furthermore there is now fuzzing of large parts of uSockets thanks to libEpollFuzzer - about 80% of non-SSL use. Overall this is a major improvement in fuzzing coverage and has led to new bugs being discovered and fixed.
- TopicTree has seen two bug fixes; one stack overflow when trimming large trees, and one CPU hang when publishing to a large tree using wildcards (which is ill-use according to MQTT).
- Minor misuse of HTTP header BloomFilter has been corrected.
