This is a new fuzzer that I'd like to test out.

Ops:
Would you mind making a trivial modification to service/gcbrun_experiment.py?
This will allow PR experiments. Here is an example to add a dummy comment : )
Thanks!

Done! Forgot about that sorry

@DonggeLiu Agh, forgot to run make presubmit and the linter had taken issue with my whitespace. I think it needs restarting? The experiment report didn't populate, so I assume it's down to the CI checks failing.

Hi @DanBlackwell
That experiment has launched: The data directory is not empty.
The report normally takes longer to show after FB finishes building the benchmarks and fuzzers.

I've manually terminated all VM instances of that experiment and will relaunch a new one to use the latest code.

The experiment report didn't populate, so I assume it's down to the CI checks failing.

The CI checks won't block PR experiments, they are separated.
But it's good that you double-checked CIs, as sometimes the fuzzer might not be compatible with some benchmarks : )

Hi @DanBlackwell
That experiment has launched: The data directory is not empty.
The report normally takes longer to show after FB finishes building the benchmarks and fuzzers.

My apologies, I thought the experiment-folders and coverage dirs in the data directory normally showed up after 1-2 hours; then when I saw the CI checks failed I jumped to the conclusion that it only ran the build and bailed.

But it's good that you double-checked CIs, as sometimes the fuzzer might not be compatible with some benchmarks : )

This fuzzer will only work on a subset for now, as DFSan requires all dependencies to be compiled with the -fsanitize=dataflow flag set (including the C++ standard library, OpenSSL etc.). If it looks promising then I'll put in some time to figure out how that can be done.

experiment name: `2024-07-08-dgfuzz-1`

Report: here
experiment data: here

DanBlackwell · 2024-07-08T19:28:54Z

@DonggeLiu Hmm, seems like it’s not started the experiment again (no experiment-folders created again). Is it possible that because it’s the only fuzzer in the experiment - and some of the targets did not build?

If so, maybe it could be run with just the 8 targets that do build. I've now added dgfuzz to all the unsupported_fuzzers fields for those that do not build, so in theory it can be run with the same gcb command. (from what I saw here, it looks like gcbrun only lets you do one benchmark at a time, is that correct?)

Additionally, I’ve set the merge_with_nonprivate flag to false just in case running less programs causes any weirdness; it would be best if we could also run libafl as a baseline / control given that it won't merge now.

If it helps, these are the 8 that build ok:

harfbuzz_hb-shape-fuzzer lcms_cms_transform_fuzzer libpcap_fuzz_both mbedtls_fuzz_dtlsclient openthread_ot-ip6-send-fuzzer stb_stbi_read_fuzzer vorbis_decode_fuzzer zlib_zlib_uncompress_fuzzer

PS, if the experiment did start at some point (it's been 5 hours without starting at the time of writing), then ignore all this and let it run through :)

I don't think this will block the experiment. If this happens, then that benchmark will be excluded from the exp without affecting others.

DanBlackwell · 2024-07-10T15:06:34Z

Hi @DonggeLiu , I've pushed up some updates - I think that last run was getting killed due to shared memory not getting freed correctly. Can you run the following:

/gcbrun run_experiment.py -a --experiment-config /opt/fuzzbench/service/experiment-config.yaml --experiment-name 2024-07-10-dgfuzz --fuzzers dgfuzz

DonggeLiu · 2024-07-11T00:22:57Z

@DonggeLiu Just a note that most of these did not build with some apt errors it seems. The following was taken from libpcap_fuzz_both:

Yep, this should be a flaky internet connection failure.
We sometimes see this but cannot do much other than re-run the exp.

Apt is still not playing ball it seems. It's trying to fetch:

http://security.ubuntu.com/ubuntu/pool/main/p/python3.8/libpython3.8_3.8.10-0ubuntu1~20.04.9_amd64.deb

Looking here it seems there is no 20.04.9, but there is 20.04.10 (python3.8-dbg_3.8.10-0ubuntu1~20.04.10_amd64.deb). ~~As to why it is trying to fetch that particular version, I don't know. The particular command that fails is copied from AFL++ builder.Dockerfile, so maybe that will have the same issue?~~

EDIT: it was missing apt-get update; I guess so far I'd got lucky that the base image was new enough that nothing had been replaced yet.

Hmm @DonggeLiu the experiment failed to build (see here) for some reason - but I can't access the logs to see what went wrong, as they're on GCP.

Note that the CI always fails for this PR, but usually the experiment builds fine.

DanBlackwell · 2024-09-05T07:55:34Z

Ok @DonggeLiu , I added the log for retcode in the measurer so I think it's worth adding zlib back in and see if we can catch what was killing it. That last run yesterday failed for some reason as mentioned in the comment above; if there's nothing suspicious in the logs and it was just flakiness then could we run the following instead? (Otherwise I'm happy to try debug if you can send me the logs)

You're right, I made a typo in the commit hash - should have been dgfuzz_22997c rather than dgfuzz_22977c. No worries, the one running now is newer (and hopefully better).
