# repo22 ACL/xattr integration smoke report

- Date: 2026-08-08 UTC
- Source baseline before this batch: `8e629bb9f798f0c76497bd2b623329a0aff430b9`
- FreeBSD guest: 15.0-RELEASE-p8 amd64, QEMU TCG
- Module SHA256: `18967bd32e89b08a2363241ed4b9b67344b7bfb555f1f77daa64f382925e4fda`
- Scope: ACL/xattr worktree integration, build/link validation, and minimal
  Markdown-directed manual smoke tests

## Results

| Check | Result | Evidence |
|---|---|---|
| `./build.sh` | PASS | `build/erofs.ko` generated without errors |
| unresolved `bcmp` | PASS | `nm -u build/erofs.ko` contains no `bcmp` |
| ACL kernel dependency | PASS | module declares `acl_posix1e`; `kldload` succeeds |
| module lifecycle | PASS | `kldload`, `kldstat`, and exact module-ID `kldunload` succeed |
| TC005 user xattr smoke | PASS | `user.comment` lists and reads as `repo22-user-xattr` |
| TC082 access ACL smoke | PASS | system xattr lists `posix_acl_access`; raw ACL reads successfully |
| FreeBSD ACL decode | PASS | `getfacl` reports named user, group, mask, and other entries |
| TC060 ACL capability | PASS | `getconf ACL_EXTENDED` returns `1` |
| read-only access smoke | PASS | read succeeds and write access is denied |
| cleanup | PASS | no EROFS module, mount, or md device remains |

The ACL fixture contained a real extended POSIX.1e access ACL with a named
user and mask, so Linux did not collapse it into mode bits. `dump.erofs`
reported 88 bytes of inode xattrs. FreeBSD returned:

```text
user::rw-
user:ntpd:r--
group::r--
mask::r--
other::---
```

The fixture image, source directory, kernel module, VM overlay, and generated
objects remained under `/work/build` or `repo22/build` and were not staged.

## Remaining scope

- Default-directory ACL retrieval and access checks under multiple credentials
  were not exercised in this smoke batch.
- Shared-xattr base calculation, long/packed prefixes, xattr filters, malformed
  xattr bounds, and metabox-backed shared xattrs still require dedicated tests.
- Multi-device work is outside this ACL/xattr integration batch.
