test(fuzzing): add internal fuzzing infra support - CHAOSPLT-1355 by edznux-dd · Pull Request #15685 · DataDog/dd-trace-py

edznux-dd · 2025-12-17T16:26:05Z

Description

This is a V1 (especially the fuzz_infra.py) because we are lacking some capabilities (see the further improvement section)

This PR adds support for the building and sending fuzzing binaries to our internal fuzzing infra on a schedule from main.
It aims to be run on a scheduled pipeline every day on main.

The goal is to fuzz important part of dd-trace-py on a daily schedule. Other important library like libddwaf and libdatadog are already onboarded!

Reporting of bugs will be done via a slack message (and datadog error tracking!) with context enrichment and bug-fix proposal!

Findings

shift exponent 36 is too large for 32-bit type 'int'

(old, not sure if it's still valid as of January 14th)
This code

_read_varint(unsigned char* table, ssize_t size, ssize_t* i)
{
    ssize_t guard = size - 1;
    if (*i >= guard)
        return 0;

    int val = table[++*i] & 63;
    int shift = 0;
    while (table[*i] & 64 && *i < guard) {
        shift += 6;
        val |= (table[++*i] & 63) << shift;
    }
    return val;
}

causes:

/src/ddtrace/internal/datadog/profiling/stack/src/echion/frame.cc:30:35: runtime error: shift exponent 36 is too large for 32-bit type 'int'

Stack overflow

After a few seconds of run, it looks like there's an infinite loop causing a stack overflow?

The crashing input can be seen as the following:

$ xxd crash-bb3bf4e4f3b69d011d393be9efcfdea8526f929d 
00000000: 0000 0010 0000 0000 1000 0000 0000 0000  ................
00000010: 0000 0000 0000 0000 0000 0000 0000 000a  ................

How do I get these findings?

Download the crash:

fuzzydog crash get --input dd-trace-py-fuzz-echion-remote-read 241ff84a464909a768523292e09a1239f9077b535e7105a570122a78a8e30532

Download the binary that was running the fuzz test (or recompile it locally)

fuzzydog build get dd-trace-py-fuzz-echion-remote-read 4df9391d51325e8d0bc81520e2bbb5ecb19e4825

Run the fuzz test only on the crashing input

./241ff84a464909a768523292e09a1239f9077b535e7105a570122a78a8e30532 ./4df9391d51325e8d0bc81520e2bbb5ecb19e4825

You can then use GDB to debug the issues.

Testing the PR

Testing locally

docker build -f docker/Dockerfile.fuzz -t ddtrace-py-stack-fuzz .
docker run -it ddtrace-py-stack-fuzz

Infra test procedure:

Manually gitlab's fuzzing pipeline of that PR. Example here
Check the datadog log for execution here
Assess that no runtime error was seen in the fuzzing execution.

Further improvements

The current process, for C codebase is quite finicky in part because of the toolchain (CMake) flexibility.
There are improvements planned in our infrastructure that would allow for end user to use Dockerfile directly with the same discovery of harness, but it's not ready yet.

Risks

This is tests only, no customer facing risk. It may find interesting bugs to be fixed.

Additional Notes

We have more extensive doc in confluence here for our fuzzing infra.
