Introduce fuzzing for payjoin by benalleng · Pull Request #1153 · payjoin/rust-payjoin

benalleng · 2025-10-07T19:27:36Z

This adds fuzzing infrastructure for payjoin with the inclusion
of three engine options, cargo-fuzz (libfuzzer-sys), afl++, and honggfuzz. These
two were chosen as they come with seperate tradeoffs in regards to speed
and error handling.

Because these two fuzzers are setup as mutually exclusive fuzzers within
the same target file fuzzing cannot reasonably be built with
--all-features.

In addition honggfuzz and afl are seemingly broken on nix so I don't think it is reasonably
possible at this time to nixify our fuzzing crate.

The readme for reading pleasure https://github.com/benalleng/rust-payjoin/blob/fuzzing/payjoin-fuzz/README.md

NB The tests that I have written are not guaranteed as good fuzzing targets and that I my hope for the mob coding session on Wednesday 1/14 next week to shore up before this is merge-able

Following the summit I thought it would be a good idea to try and follow the way that rust-lightning builds their fuzz infra https://github.com/lightningdevkit/rust-lightning/tree/main/fuzz with multiple fuzz suites, however I cannot get honggfuzz running on my machine for the life of me, maybe a personal nix problem but I also found this comment rust-fuzz/honggfuzz-rs#106 so I am not totally sure if there is a larger issue with hongfuzz at the moment.

benalleng · 2026-01-06T23:06:11Z

I excluded fuzzing from linting as the crate does not follow --all-features namely looking for a user to choose the fuzzing engine with a specific feature flag

benalleng · 2026-01-15T16:05:09Z

I have added these 2 pre-configurations to the fuzz shells as it seems easier for most people to simply skip these optimizations but if we want to have a more efficient we probably need to address these.

Your system is configured to send core dump notifications to an
    external utility. This will cause issues: there will be an extended delay
    between stumbling upon a crash and having this information relayed to the
    fuzzer via the standard waitpid() API.
    If you're just experimenting, set 'AFL_I_DONT_CARE_ABOUT_MISSING_CRASHES=1'.

    To avoid having crashes misinterpreted as timeouts, please 
    temporarily modify /proc/sys/kernel/core_pattern, like so:

    echo core | sudo tee /proc/sys/kernel/core_pattern

and

Whoops, your system uses on-demand CPU frequency scaling, adjusted
    between 1075 and 5139 MHz. Unfortunately, the scaling algorithm in the
    kernel is imperfect and can miss the short-lived processes spawned by
    afl-fuzz. To keep things moving, run these commands as root:

    cd /sys/devices/system/cpu
    echo performance | sudo tee cpu*/cpufreq/scaling_governor

    You can later go back to the original state by replacing 'performance'
    with 'ondemand' or 'powersave'. If you don't want to change the settings,
    set AFL_SKIP_CPUFREQ to make afl-fuzz skip this check - but expect some
    performance drop.

[-] PROGRAM ABORT : Suboptimal CPU scaling governor
         Location : check_cpu_governor(), src/afl-fuzz-init.c:2753

Again I don't these are critical for CI fuzzing or just running the ./fuzz.sh script but I do believe that if we want say a long-running fuzzer these could result in significant performace holdups.

The docs are less helpful than I would hope https://afl-1.readthedocs.io/en/latest/user_guide.html#settings-for-afl-fuzz

If you are Jakub, you may need AFL_I_DONT_CARE_ABOUT_MISSING_CRASHES. Others need not apply.

Edit: Maybe just a readme step telling users to follow those 2 steps as setup for afl is sufficient

nothingmuch

these changes partially fix:

cargo-honggfuzz package name
applying the overlay instead of only re-exporting it as an output of our flake
adding this package to the environment
crate & honggfuzz version mismatch

however, bash fuzz.sh hfuzz still fails to build, due to a C compilation error:

we should probably copy fedimint's homework here

Is this mostly blocked on review (ignoring that CI timeout)? Open 4 mo is quite a while for something that we're sure we want some MVP of at least.

benalleng · 2026-01-29T14:24:17Z

I would say the true blocker is the dev shell needing some upstream updates to make it a more one-click experience. It could definitely use a review in its current state as I believe some enhancements can be made after merge. The most I would like is an update to the readme to point out that the nix develop shell does not actually work for all engines at the moment. Testing is probably best done using libfuzzer (cargo fuzz)

This commit adds fuzzing infrastructure for payjoin with the inclusion of three engine options, cargo-fuzz (libfuzzer-sys), afl++, and honggfuzz. These two were chosen as they come with seperate tradeoffs in regards to speed and error handling. Because these two fuzzers are setup as mutually exclusive fuzzers within the same target file fuzzing cannot reasonably be built with `--all-features`. In addition honggfuzz and afl are seemingly broken on nix so I don't think it is reasonably possible at this time to nixify our fuzzing crate.

DanGould · 2026-02-03T06:29:39Z

This comment is very confusing to me. If dev shell upstream updates is a blocker, how can this be merged? Is the only blocker actually review?

three or two? Which tradeoffs apply to our project in such a significant way you didn't just pick one? The why is almost there but missing enough detail for the next person to pick up where you left off to understand why this decision was made in comparison with others available.

DanGould · 2026-02-03T06:33:56Z

honggfuzz and afl are seemingly broken on nix

If hongfuzz is broken on nix why are we including it here? Or is this different because it is cargo-hongfuzz.

Please document open questions and commit the tiny uncontroversial set of changes so that we can just merge and stop spinning wheels.
