# SyzFix — Fixed Linux Kernel Bugs, Full Lifecycle

**7,000+ fixed Linux kernel bugs** from [syzbot](https://syzkaller.appspot.com/upstream/fixed),
each captured end-to-end: the raw crash report, syzkaller/C reproducers, every
patch revision posted to lore.kernel.org with its review discussion, and the
final commit merged into `torvalds/linux`.

> **Code & docs:** https://github.com/sysec-uic/syzfix ·
> **Website:** https://sysec-uic.github.io/syzfix/

## What's in the repo

| Path | Contents |
|---|---|
| `data/train-*.parquet` | The structured dataset — one record per bug (schema below) |
| `processed/processed.jsonl.gz` | Full per-bug JSON (~2 GB gz, ~11 GB unpacked): complete mailing-list threads, all crash variants, raw syzbot fields |

## Record schema (main dataset)

| Field | Description |
|---|---|
| `bug_id`, `title`, `status` | syzbot bug identity |
| `crash_report` | Full kernel oops / KASAN / BUG output |
| `c_reproducer`, `syz_reproducer` | Reproducers when available |
| `fix_commit_*` | Hash, title, author, date of the merged fix |
| `final_patch_diff` | The merged patch |
| `patch_evolution` | JSON: v1 → v2 → … diffs with inline discussions |
| `num_patch_versions`, `has_discussion` | Convenience flags |

## Usage

```python
from datasets import load_dataset

ds = load_dataset("xiaoguangwang/syzfix-dataset")   # the structured dataset
print(ds["train"][0]["title"])
```

Full per-bug JSON (for custom processing / re-deriving training tasks):

```bash
pip install "syzfix @ git+https://github.com/sysec-uic/syzfix"
python -m dataset.restore_processed --repo xiaoguangwang/syzfix-dataset
```

## Updates

The dataset tracks syzbot continuously; it is refreshed by an incremental
crawler (`python -m dataset.update` in the GitHub repo).

lore.kernel.org, git.kernel.org and patchwork.kernel.org. Kernel patches and
