A Proof of Error in `python-libnmap-0.7.2`

4

1. A docker environment to show the proof of the error. 2. wrappers to feed inputs to `python-libnmap-0.7.2`.

Set LIB_FUZZING_ENGINE for arrow_parquet-arrow-fuzz

1

Link env variable `LIB_FUZZING_ENGINE` to Centipede's lib file, as required by benchmark `arrow_parquet-arrow-fuzz`. Unfortunately, this does not solve the `undefined reference to '__sanitizer_cov_load8'` error.

`arrow_parquet-arrow-fuzz` does not use `FUZZER_LIB`

3

How do fuzzers who requires `FUZZER_LIB` work with benchmark `arrow_parquet-arrow-fuzz`? The [build script of that benchmark](https://github.com/google/fuzzbench/blob/master/benchmarks/arrow_parquet-arrow-fuzz/build.sh) does not seem to make use of `FUZZER_LIB`.

`Centipede` integration (engine)

Implements the fuzzing engine interface of `Centipede`, as the first of a series of PRs for `Centipede` integration.

Centipede modes

1

Add different modes of `Centipede` for coverage experiments: * [Default](https://github.com/google/fuzzbench/blob/master/fuzzers/centipede/fuzzer.py#L71) (no extra flags) * `--use_counter_features=1` * `--use_corpus_weights=0` * `--use_coverage_frontier=1` * `--max_corpus_size=1000` * `--max_corpus_size=10000` * `--use_cmp_features=0` * `--path_level=5` * `--path_level=10` *...

As we start to have many reports (from daily, one-off, pr), I wanted to use sub-directory as an easy way to visually categorize reports to keep the directory more organized....
