Local experiment issue : ERRO[0612] error waiting for container: unexpected EOF - [SOLVED]

[Microsvuln]

Hi.

I have a problem running local experiments, I get the following error while building benchmarks after running this :

(.venv) arash@fuzzbench-scale1:~/new/fuzzbench$ PYTHONPATH=. python3 experiment/run_experiment.py --experiment-config experiment-config.yaml --benchmarks bloaty_fuzz_target harfbuzz-1.3.2 libjpeg-turbo-07-2017 libpcap_fuzz_both libpng-1.2.56 libxml2-v2.9.2 --experiment-name $EXPERIMENT_NAME --fuzzers afl aflql

And the error log (summarized) :

I don't know why this is happening but the number of fuzzers is 2 and the number of benchmarks is 6, even though I want to run many more of fuzzers and benchmarks.

Any solution to this?

Thanks.

What are the specs of your machine? How many cores and how much RAM?
I think this issue is moby/moby#36324
If this is the case, adding in some resource control to local experiments should help.

[Microsvuln]

@jonathanmetzman

96 Cores of CPU and 64GB of RAM.

Had no problem with this machine before, I don't know if fuzzbench updates affect this.

Will try this and let you know about it.

[jonathanmetzman]

Hmmm...Maybe not then.
One possible issue with builds on a single machine could be that each docker build might use as many cores as possible (e.g. make -j $NPROC). Maybe we need to limit this?

[Microsvuln]

@jonathanmetzman

Nope, I can confirm that I found how to reproduce this and how to solve this problem.

Description
A fuzzbench local experiment would not be run successfully and will raise the ERROR[0585] error waiting for container: unexpected EOF error if the following condition is met :

If you add your private fuzzer to the fuzzbench fuzzer directory BEFORE you install the fuzzbench using the following commands:

$ make install-dependencies
$ source .venv/bin/activate
$ make presubmit

Here we assume that the Fuzzbench user has a customized/private fuzzer and aims to add his fuzzer to fuzzbench and run a local experiment.

Solution

1. Clone the fuzzbench github repository
2. Make sure that you didn't add anything to fuzzbench before installing it.
3. Try to install the fuzzbench as mentioned in the documentation.
4. After you installed the fuzzbench successfully, then try to add your fuzzer directory to fuzzer directory of fuzzbench and check it using the following commands :

$ make format
$ make presubmit

Now the experiment will be run successfully.

P.S 1 . Please make sure that your fuzzer has been added to fuzzbench AFTER the fuzzbench installation process.

P.S 2 . I managed to solve most of the local experiment issues I faced, if you like I can open a troubleshooting section in the fuzzbench documentation and add them along with solutions so a fuzzbench user has the chance to find the solution more quickly.

Problem solved, issue closed.

Thanks.

I need to understand what happened here, so reopening.

I can see the same issue on my side with this commit (ed0dba7) when use the run script to start the experiment. But the command "make-debug--" runs fine.

@chenju2k6 - can you please provide steps to reproduce.

[chenju2k6]

Sure. This error happens if I add customized new fuzzers: exp_fuzzer1, exp_fuzzer2 . However, the unit testing "make-exp_fuzzer1-xxx" runs fine. I am wondering if there are any other sanity checks we can run before we schedule an experiment?

Any news on this? I am experiencing the problem and I am willing to help debugging. I have tried the procedure suggested above, but it did not help. What does help is reducing the number of benchmarks being targeted.

It depends on how many benchmarks and fuzzers I choose. I don't use custom fuzzers only supported once.
For example this run string fails:

PYTHONPATH=. python3 experiment/run_experiment.py \
--experiment-config ../experiment-config.yaml \
--benchmarks lcms-2017-03-21 freetype2-2017 libpng-1.2.56 \
--experiment-name test-local-fuzzbench \
--fuzzers aflplusplus libfuzzer fuzzolic_aflplusplus_z3

But this string works fine (removed one benchmark):

PYTHONPATH=. python3 experiment/run_experiment.py \
--experiment-config ../experiment-config.yaml \
--benchmarks lcms-2017-03-21 freetype2-2017  \
--experiment-name test-local-fuzzbench \
--fuzzers aflplusplus libfuzzer fuzzolic_aflplusplus_z3

My machine has 128cpu 500gb memory.
