|
||
|
||
| 项目 | 结果 | 证据 |

|
||
| TC009-statfs-basic | BLOCKED / NOT RUN | 仅在 TC001 通过后执行；TC001 未执行 |
|
||
|
||
## 1. 初始 SSH 验证
|
||
|
||
首次按题目给出的普通 SSH 方式验证，端口可达，但 guest 不接受宿主默认公钥。
|
||
|
||
实际命令：
|
||
|
||
```sh
|
||
ssh -o BatchMode=yes -o StrictHostKeyChecking=accept-new \
|
||
-o ConnectTimeout=8 -p 9222 [email protected] \
|
||
'echo "== identity =="; id; echo "== uname =="; uname -a'
|
||
```
|
||
|
||
实际输出：
|
||
|
||
```text
|
||
Warning: Permanently added '[127.0.0.1]:9222' (ED25519) to the list of known hosts.
|
||
[email protected]: Permission denied (publickey,keyboard-interactive).
|
||
```
|
||
|
||
检查现有 VM 基线文档后，确认该 guest 使用固定测试密码和
|
||
`keyboard-interactive,password`。宿主没有 `sshpass`，因此创建了仅用于 SSH/SCP
|
||
认证的临时 `/tmp/repo22-ssh-askpass.sh`；它不是测试 wrapper，未写入仓库。
|
||
|
||
实际命令：
|
||
|
||
```sh
|
||
cat > /tmp/repo22-ssh-askpass.sh <<'EOF'
|
||
#!/bin/sh
|
||
printf '%s\n' '<固定测试密码>'
|
||
EOF
|
||
chmod 700 /tmp/repo22-ssh-askpass.sh
|
||
```
|
||
|
||
随后所有 SSH/SCP 命令使用以下认证前缀和选项：
|
||
|
||
```sh
|
||
DISPLAY=:0 SSH_ASKPASS=/tmp/repo22-ssh-askpass.sh \
|
||
SSH_ASKPASS_REQUIRE=force setsid -w ssh \
|
||
-o StrictHostKeyChecking=no \
|
||
-o UserKnownHostsFile=/dev/null \
|
||
-o PreferredAuthentications=keyboard-interactive,password \
|
||
-o PubkeyAuthentication=no \
|
||
-p 9222 [email protected] '<guest command>'
|
||
```
|
||
|
||
## 2. Guest 环境验证
|
||
|
||
实际 guest 命令：
|
||
|
||
```sh
|
||
echo "== UTC date =="; date -u "+%Y-%m-%dT%H:%M:%SZ"
|
||
echo "== identity =="; id
|
||
echo "== uname =="; uname -a
|
||
echo "== freebsd-version =="; freebsd-version -ku 2>&1
|
||
echo "== hostname =="; hostname
|
||
echo "== architecture =="; uname -m; sysctl -n hw.machine_arch 2>&1
|
||
echo "== securelevel =="; sysctl kern.securelevel
|
||
echo "== module tools =="; command -v kldload; command -v kldstat; command -v kldunload
|
||
echo "== filesystem tools =="; command -v mdconfig; command -v mount; command -v umount; command -v sha256; command -v stat
|
||
echo "== existing erofs module/mount/md =="; kldstat | grep -i erofs || true; mount | grep -i erofs || true; mdconfig -l
|
||
echo "== temp space =="; df -h /tmp /root
|
||
```
|
||
|
||
实际输出：
|
||
|
||
```text
|
||
Warning: Permanently added '[127.0.0.1]:9222' (ED25519) to the list of known hosts.

|
||
```
|
||
|
||
结论：guest 连接及基础环境 PASS；开始时没有已加载 EROFS 模块、EROFS 挂载或 md 设备。
|
||
|
||
## 3. 等待 ABI 提交
|
||
|
||
轮询条件：HEAD 必须晚于测试开始时的 `db524d69f`，且
|
||
`git status --porcelain -- repo-community/repo22` 行数必须为 0。
|
||
|
||
实际命令：
|
||
|
||
```sh
|
||
baseline=db524d69f
|
||
for attempt in $(seq 1 40); do
|
||
now=$(date -u '+%Y-%m-%dT%H:%M:%SZ')
|
||
head=$(git rev-parse --short HEAD)
|
||
subject=$(git log -1 --pretty=%s)
|
||
dirty=$(git status --porcelain -- repo-community/repo22 | wc -l)
|
||
printf '%s attempt=%02d HEAD=%s dirty_repo22=%s subject=%s\n' \
|
||
"$now" "$attempt" "$head" "$dirty" "$subject"
|
||
if [ "$head" != "$baseline" ] && [ "$dirty" -eq 0 ]; then
|
||
echo 'READY: repo22 has a newer commit and its scoped worktree is clean'
|
||
git log --date=iso-strict -5 --pretty=format:'%h %ad %an %s'
|
||
echo
|
||
exit 0
|
||
fi
|
||
sleep 15
|
||
done
|
||
```
|
||
|
||
实际输出：
|
||
|
||
```text

```
|
||
|
||
## 4. 宿主构建 repo22 erofs.ko
|
||
|
||
实际命令（工作目录 `/work/repo-community/repo22`）：
|
||
|
||
```sh
|
||
date -u '+%Y-%m-%dT%H:%M:%SZ'
|
||
git rev-parse HEAD
|
||
clang --version | head -1
|
||
FREEBSD_SRC=/work/dev-freebsd-releng ./build.sh
|
||
echo "build_exit=$?"
|
||
ls -l --full-time build/erofs.ko
|
||
sha256sum build/erofs.ko
|
||
```
|
||
|
||
实际输出（编译器对 FreeBSD 内核头文件产生了多组重复的 builtin redeclaration
|
||
warning；构建未使用 `-Werror`，没有编译或链接 error）：
|
||
|
||

||

|
||
|
||
## 5. SCP 模块到 guest
|
||
|
||
实际命令（密码由临时 askpass 提供）：
|
||
|
||
```sh
|
||
DISPLAY=:0 SSH_ASKPASS=/tmp/repo22-ssh-askpass.sh \
|
||
SSH_ASKPASS_REQUIRE=force setsid -w scp -O \
|
||
-o StrictHostKeyChecking=no \
|
||
-o UserKnownHostsFile=/dev/null \
|
||
-o PreferredAuthentications=keyboard-interactive,password \
|
||
-o PubkeyAuthentication=no \
|
||
-P 9222 build/erofs.ko [email protected]:/root/repo22-erofs.ko
|
||
echo "scp_exit=$?"
|
||
```
|
||
|
||
实际输出：
|
||
|
||
```text
|
||
Warning: Permanently added '[127.0.0.1]:9222' (ED25519) to the list of known hosts.
|
||
scp_exit=0
|
||
```
|
||
|
||
guest 校验命令：
|
||
|
||
```sh
|
||
ls -l /root/repo22-erofs.ko
|
||
sha256 /root/repo22-erofs.ko
|
||
```
|
||
|
||
实际输出：
|
||
|
||
```text
|
||
-rw-r--r-- 1 root wheel 45088 Aug 8 11:13 /root/repo22-erofs.ko
|
||
SHA256 (/root/repo22-erofs.ko) = f119bb2c902bf6e221b532b1c8e7668caaa5c744c46b4eac8f9f105cd7494e9f
|
||
```
|
||
|
||
结论：复制成功且字节身份一致。
|
||
|
||
## 6. Guest 手工模块加载测试
|
||
|
||
### 6.1 加载前状态与 dmesg
|
||
|
||
实际命令：
|
||
|
||
```sh
|
||
kldstat | grep -i erofs
|
||
echo "pre_kldstat_grep_exit=$?"
|
||
dmesg | tail -30
|
||
```
|
||
|
||
实际输出：
|
||
|
||
```text
|
||

|
||
```
|
||
|
||
### 6.2 kldload
|
||
|
||
实际命令：
|
||
|
||
```sh
|
||
kldload /root/repo22-erofs.ko
|
||
echo "kldload_exit=$?"
|
||
```
|
||
|
||
实际输出：
|
||
|
||
```text
|
||
kldload: an error occurred while loading module /root/repo22-erofs.ko. Please check dmesg(8) for more details.
|
||
kldload_exit=1
|
||
```
|
||
|
||
失败后的实际 dmesg 命令：
|
||
|
||
```sh
|
||
dmesg | tail -80
|
||
```
|
||
|
||
实际输出末尾（失败相关行）：
|
||
|
||
```text
|
||
link_elf_obj: symbol bcmp undefined
|
||
linker_load_file: /root/repo22-erofs.ko - unsupported file type
|
||
```
|
||
|
||
最终复核命令：
|
||
|
||
```sh
|
||
date -u "+%Y-%m-%dT%H:%M:%SZ"
|
||
kldstat | grep -i erofs
|
||
echo "kldstat_grep_exit=$?"
|
||
mount | grep -i erofs
|
||
echo "mount_grep_exit=$?"
|
||
mdconfig -l
|
||
dmesg | grep -E "bcmp|repo22-erofs|linker_load_file" | tail -20
|
||
ls -l /root/repo22-erofs.ko
|
||
sha256 /root/repo22-erofs.ko
|
||
```
|
||
|
||
实际输出：
|
||
|
||
```text
|
||
2026-08-08T11:14:44Z
|
||
kldstat_grep_exit=1
|
||
mount_grep_exit=1
|
||
link_elf_obj: symbol bcmp undefined
|
||
linker_load_file: /root/repo22-erofs.ko - unsupported file type
|
||
-rw-r--r-- 1 root wheel 45088 Aug 8 11:13 /root/repo22-erofs.ko
|
||
SHA256 (/root/repo22-erofs.ko) = f119bb2c902bf6e221b532b1c8e7668caaa5c744c46b4eac8f9f105cd7494e9f
|
||
```
|
||
|
||
结论：**模块加载 FAIL**。失败不是 SCP 损坏导致，因为宿主和 guest 哈希完全一致。
|
||
FreeBSD 内核链接器无法解析模块引用的 `bcmp` 符号。
|
||
|
||
### 6.3 kldstat 与 kldunload
|
||
|
||
- 加载后的 `kldstat` 验证：**BLOCKED**。加载操作返回 1，最终复核也确认没有 EROFS 模块。
|
||
- `kldunload erofs`：**BLOCKED / NOT RUN**。模块从未成功加载；执行卸载不能构成有效卸载测试。
|
||
- 已按“任何步骤失败立即记录并停止”要求停止，没有尝试替换模块、修改 guest、绕过未解析符号或继续文件系统测试。
|
||
|
||
## 7. mkfs.erofs 与 plain 镜像
|
||
|
||
宿主工具前置检查实际命令：
|
||
|
||
```sh
|
||
command -v mkfs.erofs
|
||
mkfs.erofs -V
|
||
```
|
||
|
||
实际输出：
|
||
|
||
```text
|
||
/usr/bin/mkfs.erofs
|
||
mkfs.erofs (erofs-utils) 1.8.6
|
||
available compressors: lz4, lz4hc, lzma, deflate, libdeflate, zstd
|
||
```
|
||
|
||
状态：**NOT RUN**。工具版本满足要求，但 `kldload` 已失败，因此没有生成源数据、
|
||
没有生成 plain 镜像、没有复制镜像到 guest。这样避免在首个失败后继续推进并产生误导性结果。
|
||
|
||
## 8. TC001-mount-basic
|
||
|
||
状态：**BLOCKED / NOT RUN**。
|
||
|
||
阻塞原因：`TC001-mount-basic.md` 的前置条件要求 FreeBSD 系统已加载 EROFS 内核模块；
|
||
本轮 `kldload /root/repo22-erofs.ko` 返回 1。因而以下命令均未执行：
|
||
|
||
```sh
|
||

## 9. TC009-statfs-basic
|
||
|
||
状态：**BLOCKED / NOT RUN**。
|
||
|
||
用户要求仅在 TC001 通过后执行 TC009。TC001 因模块加载失败没有进入测试步骤，故
|
||
`df -h`、`df -i`、`stat -f` 和只读标志检查均未执行。
|
||
|
||
## 10. 工作树与提交状态
|
||
|
||
ABI 提交完成后的实际确认：
|
||
|
||
```text
|
||
HEAD=f2caaae2890a910d0f11547d9ff5f7cf92c062a2
|
||
git status --porcelain -- repo-community/repo22
|
||
<无输出>
|
||
```
|
||
|
