2020-07-30Remove redundant F_SETSIG call from process forkStefan Bucur
Setting the signal on a file descriptor to SIGIO should be redundant, according to the POSIX specification. Moreover, this system call currently prevents Honggfuzz from running inside a gVisor sandbox.

2018-01-21Support external fuzzer and provide code coveragedobin
Aka The FFW honggfuzz patch. This proposed patch for honggfuzz is used by the fuzzing for worms (FFW) framework available here: github.com/dobin/ffw This patch makes it possible to use honggfuzz as a code coverage tool for long-living (network-) servers. It provides the following functionality: * A socket interface for an external fuzzer * Support for code coverage of long living processes The socket interface supports the following messages: * Honggfuzz -> Fuzzer: "Fuzz": Send fuzz data to target * Honggfuzz -> Fuzzer: "Cras": Target crashed * Honggfuzz -> Fuzzer: "New!": New basic block reached * Fuzzer -> Honggfuzz: "okay": Fuzzer sent his stuff to target * Fuzzer -> Honggfuzz: "bad!": The server is unreachable Honggfuzz will implement the following tasks: * Start the target * Restart the target if it crashes * Restart the target if a crash/hang is detected by the fuzzer * Provide code coverage information about new basic blocks An example vulnerable server plus tests have been provided in the `socketfuzzer/` directory.
