This is activated when H2O is build with `cmake -DBUILD_FUZZER=ON`, it also needs `clang` as compiler.
Those were generated with the unit tests and `fuzz/gather-data.patch` set.
that we don't get in the way of the backtracer.
Instead of spawning a thread for each client request, instantiate one at the start of the fuzzer, then feed the client via `job_queue`.
- Add a 10s timeout for proxy IO - Have epoll timeout every 10ms to inspect the fd sooner
a fixed version (29d1659edabe4ba2396f9697915bb7a0880cbd2f) for now

Awesome pull request! I have a FreeBSD box that sits around mostly Idle for continuous integration. Il try and get this running on that later this weekend, might as well use those cores for something useful. |

@hbowden thanks! Please note that I haven't tested a wide variety of compilers. We've been using clang-3.9. |

Thank you for the great PR! |

This PR adds two fuzzers (one that accepts HTTP/1, another that accepts HTTP/2), using http://llvm.org/docs/LibFuzzer.html. They use a seed corpus (found under
fuzz/http{1,2}-corpus) that was collected by running the unit tests.The fuzzer consists of a client thread that accepts input from libFuzzer and uses it to communicate with h2o.
We use the
BUILD_FUZZERcmake directive in order to compile it (it's off by default).fuzz/README.mdfile contains the detailed instructions for compiling and running the fuzzer.The intent is to submit this for use with https://github.com/google/oss-fuzz
