Library for coverage-guided fuzz testing

LibFuzzer is a library for in-process, coverage-guided, evolutionary fuzzing of other libraries.

LibFuzzer is similar in concept to American Fuzzy Lop (AFL), but it performs all of its fuzzing inside a single process. This in-process fuzzing can be more restrictive and fragile, but is potentially much faster as there is no overhead for process start-up.

The fuzzer is linked with the library under test, and feeds fuzzed inputs to the library via a specific fuzzing entrypoint (aka 'target function'); the fuzzer then tracks which areas of the code are reached, and generates mutations on the corpus of input data in order to maximize the code coverage. The code coverage information for libFuzzer is provided by LLVM's SanitizerCoverage instrumentation.
