Optimal target analysis

Remaining optimal interesting functions

The following table shows a list of functions that are optimal targets. Optimal targets are identified by finding the functions that in combination, yield a high code coverage.

Implementing fuzzers that target the above functions will improve reachability such that it becomes:

All functions overview

If you implement fuzzers for these functions, the status of all functions in the project will be:

This sections provides heuristics that can be used as input to a fuzz engine when running a given fuzz target. The current focus is on providing input that is usable by libFuzzer.
