[Libguestfs] [PATCH nbdkit 0/2] Implement fuzzing using Clang's libFuzzer.

libFuzzer is Clang's fuzzer, and alternative to using AFL: https://llvm.org/docs/LibFuzzer.html I implemented an alternative method of fuzzing for libnbd earlier today and it's pretty simple: https://github.com/libguestfs/libnbd/commit/c19a6fbae9a21a7d4693418706c59... However it's considerably more difficult to use libFuzzer with non-library code -- in this case nbdkit. I think the first patch in this series has some merit on its own. The second patch does a lot of pretty ugly stuff to turn nbdkit into a long-running process as required by libFuzzer. It does kind of work, although it leaks a few MB of memory for each minute that you run the fuzzer which is less than ideal. Rich.
