This is ongoing work. + +## Launching the fuzzers +The easiest way to launch the fuzzers are to go through OSS-Fuzz. The only prerequisite to this is having Docker installed. + +With Docker installed, the following commands will build and run the fuzzers in this directory: + +``` +git clone https://github.com/google/oss-fuzz +cd oss-fuzz +python3 infra/helper.py build_image librdkafka +python3 infra/helper.py build_fuzzers librdkafka +python3 infra/helper.py run_fuzzer librdkafka FUZZ_NAME +``` +where FUZZ_NAME references the name of the fuzzer. Currently the only fuzzer we have is fuzz_regex + +Notice that the OSS-Fuzz `helper.py` script above will create a Docker image in which the code of librdkafka will be built. As such, depending on how you installed Docker, you may be asked to have root access (i.e. run with `sudo`). + + +## Running a single reproducer + +Download the reproducer file from the OSS-Fuzz issue tracker, then build +the failed test case by running `make` in this directory, and then +run the test case and pass it the reproducer files, e.g: + + $ make + $ ./fuzz_regex ~/Downloads/clusterfuzz-testcase-... + +**Note:** Some test cases, such as fuzz_regex, requires specific librdkafka + build configuration. See the test case source for details. |
