Fuzzers

To run a fuzzer locally, you need go-fuzz installed.

First build a fuzzing-binary out of the selected package:

(cd ./rlp && CGO_ENABLED=0 go-fuzz-build .)

That command should generate a rlp-fuzz.zip in the rlp/ directory. If you are already in that directory, you can do

[user@work rlp]$ go-fuzz
2019/11/26 13:36:54 workers: 6, corpus: 3 (3s ago), crashers: 0, restarts: 1/0, execs: 0 (0/sec), cover: 0, uptime: 3s

Otherwise:

go-fuzz -bin ./rlp/rlp-fuzz.zip

Notes

Once a 'crasher' is found, the fuzzer tries to avoid reporting the same vector twice, so stores the fault in the suppressions folder. Thus, if you e.g. make changes to fix a bug, you should remove all data from the suppressions-folder, to verify that the issue is indeed resolved.

Also, if you have only one and the same exit-point for multiple different types of test, the suppression can make the fuzzer hide different types of errors. So make sure that each type of failure is unique (for an example, see the rlp fuzzer, where a counter i is used to differentiate between failures:

		if !bytes.Equal(input, output) {
			panic(fmt.Sprintf("case %d: encode-decode is not equal, \ninput : %x\noutput: %x", i, input, output))
		}
