Guest: FreeBSD 15.0-RELEASE-p8 amd64, QEMU TCG

|
## Scope and Result
|
|
|
|
| Test | Result | Evidence |
|
|
|---|---|---|
|
|
| TC154 per-inode NFS generation | PASS | Same-image remount, same-superblock replacement, malformed replacement |
|
|
| TC155 explicit extent `pa + plen` overflow | PASS | Repeated `ERR#97` and DTrace device-I/O observation |
|
|
| TC156 inode timestamp validation | PASS | Five compact/extended corruption fixtures returned `ERR#97` |
|
|
|
|
## Build Results
|
|
|
|
Both builds ran natively in the guest with
|
|
`FREEBSD_SRC=/tmp/repo22-freebsd15-src` and completed with kernel `-Werror`.
|
|
|
|
| Configuration | Module SHA256 | Result |
|
|
|---|---|---|
|
|
| `WITH_ZSTDIO=0` | `d6e755c7a75dd5043b603d58215ae3e7c8f29318b31dc1885aa9bb070d6e57a5` | PASS |
|
|
| `WITH_ZSTDIO=1` | `b442f9f05af1d1a76801690c83c9a40ec6fc739adb0663e7dacaf837eeb2ecf3` | PASS |
|
|
|
|
The disabled module had no undefined `ZSTD_*` or `bcmp` symbol. The enabled
|
|
module referenced only the expected FreeBSD kernel ZSTD API symbols and no
|
|
`bcmp`.
|
|
|
|
## Fixture Reproduction
|
|
|
|
`python3 tests/review_fixtures.py make` was run twice in independent empty
|
|
directories with erofs-utils 1.8.6. All nine images were byte-identical between
|
|
runs, and both `SHA256SUMS` files self-verified.
|
|
|
|
| Fixture | SHA256 |

|
|
|
|
## TC154
|
|
|
|
Image A reported FID `len=16`, `pad=0`, NID 452, and generation
|
|
`3895653226`; `fhstat`, `stat -f %v`, and the fixture manifest agreed. Reusing
|
|
md90 for an unchanged-image remount preserved the complete handle and the old
|
|
handle remained readable.
|
|
|
|
Image B retained fsid `00000034:000000e0` and NID 452 but reported generation
|
|
`548470773`. Both `fhstat` and `fhopen` on A's handle returned `ESTALE`; B's
|
|
handle succeeded. With the malformed replacement, both old-handle operations
|
|
returned positive FreeBSD errno 45 (`EOPNOTSUPP`).
|
|
|
|
## TC155
|
|
|
|
The fixture mounted and `stat` reported the 1 MiB target. Two direct reads at
|
|
logical offset 4096 exited 1; both independent truss runs showed:
|
|
|
|
```text
|
|
read(..., 1) ERR#97 'Integrity check failed'
|
|
```
|
|
|
|
An `io:::start` DTrace positive control captured a raw md90 read at physical
|
|
offset 4096. The failing EROFS read produced no md90 I/O event, proving the
|
|
wrapped physical address did not reach the provider.
|
|
|
|
## TC156
|
|
|
|
`compact-epoch-wrap` and `compact-nsec-invalid` failed mount directly with rc 1
|
|
and traced `nmount(...)=ERR#97`. `compact-epoch-range` mounted with root mtime
|
|
`INT64_MAX`, while target stat returned `ERR#97`. Both extended target fixtures
|
|
mounted successfully and returned `ERR#97` for invalid nanoseconds and
|
|
`INT64_MAX+1` seconds. Every failing operation was executed directly and again
|
|
under truss.
|
|
|
|
## Harness Notes
|
|
|
|
The first build invocation used absent `/usr/src` and was rerun with the actual
|
|
guest source path. One test attempt used an overly narrow KLD filename match and
|
|
executed no TC step. A second attempt discarded `truss`'s zero wrapper status;
|
|
the qualified runs record direct command status separately from traced syscall
|
|
errno. None of these discarded attempts is counted as PASS evidence.
|
|
|
|
## Cleanup
|
|
|
|
Each qualified run ended with unchanged dmesg line count (`123 -> 123`), zero
|
|
EROFS mounts, no md provider, and zero EROFS modules. Raw transcripts, build
|
|
objects, modules, and generated images remain outside the repository under
|
|
`/work/build` and guest `/tmp` only.
