[Wireshark-dev] American Fuzzy Lop - Menagerie Minimization
Gerald and I have (independently) started playing with the American Fuzzy Lop fuzzer recently [1] as a possibly more intelligent alternative or complement to our current fuzzing set-up. It includes a tool afl-cmin that uses its instrumentation to find unnecessary files in a set of inputs (i.e. files that don't exercise any new paths compared to the rest of the inputs). As an experiment, I ran this tool against tshark -nr on our currently available public menagerie folder and it cut it about in half. Before: 5726 files, 1.8G After: 2423 files, 764M I suspect with tshark -nxVr there are more paths and fewer duplicates (and it would also take a lot longer to run the script) but it may be worth investigating regardless. If anybody else is curious about the results I've made the minimized file list available at [2].
