panic したので保存された crash dump を mdb で解析してもらい原因を突き止めてもらうセッションログ

[satokaz]

(原因はある程度当たりがつく) panic が発生したので、ちょうど良いやと codex を使って原因を突き止めてもらったログ (codex のsession log から生成)。
どういう流れで作業するのか眺めたく(クソ長い

結論:

解析結果です。結論から言うと、今回の panic は tun/tap カーネルモジュール起因です。

• 発生: 2026-03-12 13:35:49 JST
• UUID: 6f01e6d3-ebee-46fe-8bf0-ac6cf2d74e8b
• panic: BAD TRAP: type=7 (#nm Device not available)

根拠:

1. panic スタックが tun:tunchmsg.constprop.0 -> tun:tunwsrv
2. trap 時の CR0 に TS ビットが立っている (...<...,ts,...>)
3. dump 内 RIP (0xfffffffff42a4991) の逆アセンブルで movd %rdx,%xmm0 など SIMD 命令が見える
4. panic 直前に tun/tap 読み込み時の署名検証失敗警告あり
   • WARNING: Signature verification of module /usr/kernel/drv/amd64/tun failed
   • .../tap failed
5. /usr/kernel/drv/amd64/tun と tap は IPS 管理外（pkg contents でヒットなし）かつ署名なし（elfsign verify）

**Explaining disassembly command hang**

[06:09:41Z] ASSISTANT FINAL
詰まっていたのは mdb の逆アセンブル (::dis) です。
/tmp/crash_analyze_6f01e6d3/vmcore.0（約 6.5GB）に対して tuntunchmsg.constprop.0` 周辺を展開する処理が長引き、戻りが来る前に中断されました。

補足:

• 既に panic スタック取得までは完了しています。
• 詰まったのは「追加の命令列解析」だけで、原因候補の関数特定まではできています。

*
* SYSTEM SPECIFICATION FILE
*

* It is highly recommened not to edit this file directly but instead
* to deliver fragments into files in /etc/system.d/
*
* The recommended naming for files in /etc/system.d/ is to use the IPS
* package name with the '/' converted to a ':' for example:
* 	pkg:/mycompany/db-server/hr-db delivers content as
* 	/etc/system.d/mycompany:db-server:hr-db
*
* When the system boot archive is generated the contents of /etc/system.d
* are placed into a secondary /etc/system file that the kernel will read
* before it reads /etc/system.



* root device and root filesystem configuration:
*
*	The following may be used to override the defaults provided by
*	the boot program:
*
*	rootfs:		Set the filesystem type of the root.
*
*	rootdev:	Set the root device.  This should be a fully
*			expanded physical pathname.  The default is the
*			physical pathname of the device where the boot
*			program resides.  The physical pathname is
*			highly platform and configuration dependent.
*
*	Example:
*		rootfs:ufs
*		rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a
*
*	(Swap device configuration should be specified in /etc/vfstab.)



* exclude:
*
*	Modules appearing in the moddir path which are NOT to be loaded,
*	even if referenced. Note that `exclude' accepts either a module name,
*	or a filename which includes the directory.
*
*	Examples:
*		exclude: win
*		exclude: sys/shmsys



* forceload:
*
*	Cause these modules to be loaded at boot time, (just before mounting
*	the root filesystem) rather than at first reference. Note that
* 	forceload expects a filename which includes the directory. Also
*	note that loading a module does not necessarily imply that it will
*	be installed.
*
*	Example:
*		forceload: drv/foo



* set:
*
*	Set an integer variable in the kernel or a module to a new value.
*	This facility should be used with caution.  See system(5).
*
*	Examples:
*
*	To set variables in 'unix':
*
*		set nautopush=32
*		set maxusers=40
*
*	To set a variable named 'debug' in the module named 'test_module'
*
*		set test_module:debug = 0x13

12. 実機検証で見つかった不整合の修正（Solaris 11.4）
- `tun.c`:
  - `tun_attach_req()` の `str->ppa` ガードを見直し、同一PPAへの `DL_ATTACH_REQ` を許可。
  - これにより `IF_UNITSEL` の `ENXIO` を解消し、`tunctl -t tun0/tap0` が成功することを確認。
- `tun-test/test.sh`:
  - `cleanup` 中の再 `unplumb` 失敗で `failed=1` が残り、成功時でも `exit 1` になる問題を修正。
  - `main()` の成功パスで `return 0` を明示。
- `tun-test/regression-test.sh`:
  - `DL_ATTACH_REQ` 互換ガード（`str->ppa != NULL && str->ppa != ppa`）の存在チェックを追加。

13. E2E テストスクリプトの追加
- `tun-test/e2e-openvpn.sh`:
  - 2ホスト構成で OpenVPN static-key を使った E2E 疎通テストを実行するスクリプトを追加。
  - `--peer`, `--local-transport-ip`, `--remote-transport-ip` を必須引数として、ローカル/リモートの `tunN` を作成・起動・疎通・クリーンアップまで自動化。
- `tun-test/Makefile.in` / `Makefile.in`:
  - `test-e2e-openvpn` ターゲットを追加し、`E2E_ARGS` 経由で引数を渡せるようにした。
- `tun-test/regression-test.sh`:
  - `e2e-openvpn.sh` の存在・構文の静的チェックを追加。
- `README.md`:
  - E2E 実行方法（必須依存とコマンド例）を追記。

14. 依存なしミニ relay E2E 経路の追加
- `tun-test/tunrelay.c`（新規）:
  - `TUNSETPPA` と `DLIOCRAW` で既存 `tunN/tapN` へ接続し、`poll()` で TUN/TAP と UDP を双方向転送する最小 relay を追加。
  - OpenVPN 等に依存せず、単体バイナリで E2E 経路検証が可能。
- `tun-test/e2e-relay.sh`（新規）:
  - 2ホストの `tunN` 作成、`ifconfig` 設定、relay 起動、`ping` 疎通、後始末までを自動化。
  - `--peer`, `--local-transport-ip`, `--remote-transport-ip` を必須引数として実行する。
- `tun-test/Makefile.in` / `Makefile.in`:
  - `tunrelay` ビルドターゲットを追加。
  - `test-e2e-relay` ターゲットを追加し、`E2E_RELAY_ARGS`（未指定時は `E2E_ARGS`）を relay スクリプトへ引き渡す。
  - `test-e2e` のデフォルトを dependency-free relay 経路へ変更。
- `tun-test/regression-test.sh`:
  - `tunrelay.c` の `TUNSETPPA` / `DLIOCRAW` / `poll()` の存在チェックを追加。
  - `test-e2e` の relay 既定化と引数フォールバック導線の静的チェックを追加。

15. 実機 panic（2026-03-12 13:35:49 JST）の原因解析と対処
- 事象:
  - 実機でドライバ動作中に panic。`panicstr` は `BAD TRAP: type=7 (#nm Device not available)`。
  - `fmdump -Vp -u 6f01e6d3-ebee-46fe-8bf0-ac6cf2d74e8b` の stack は `tun:tunchmsg.constprop.0 -> tun:tunwsrv`。
- 原因:
  - `configure.in` には no-FPU/no-SSE フラグ修正を入れていたが、生成済み `configure` が古いままで未同期。
  - その結果、実機で `./configure` 後の `Makefile` `KCFLAGS` に `-mno-mmx -mno-sse -mno-sse2 -msoft-float` が入らず、カーネルモジュールに不適切な命令列が混入した可能性が高い。
- 対処:
  - `configure` 本体へ no-FPU/no-SSE フラグ反映（`NOFP_KCFLAGS_GCC` / `NOFP_KCFLAGS_STUDIO`）。
  - amd64/GCC 分岐の条件を `MINOR_VERSION` ではなく `GCC_MINOR_VERSION` へ修正。
  - `tun-test/regression-test.sh` に `configure` 本体の静的検証（no-FPU flags と条件式）を追加し、再発防止。
- 修正後確認:
  - 実機で再 `./configure` 後、`KCFLAGS` に `-mno-mmx -mno-sse -mno-sse2 -mno-80387 -msoft-float` が含まれることを確認。
  - 実機で `gmake clean && gmake && sudo gmake install` 後、`tunctl -t tun0 -b` / `tunctl -d tun0 -b` の smoke 実行時に新規 panic は発生せず。

16. 実機 panic（2026-03-12 14:04:40 JST）の追加解析
- 事象:
  - `fmdump -Vp` の UUID `6ce6b4dd-98e6-4cbd-8656-db6a95f7bc2e` で `BAD TRAP: type=7 (#nm Device not available)` を確認。
  - stack は前回と同じく `tun:tunchmsg.constprop.0 -> tun:tunwsrv`。
- 直接原因:
  - panic時に使われた `tun` バイナリを `dis` すると、`tunchmsg.constprop.0` ほかに `xmm` 命令（`movdqa`, `movups`, `punpcklqdq`）が存在。
  - カーネル内で SSE 命令実行により `#nm` が発生したと判断。
- なぜ混入したか:
  - 実機ビルドログが `Nothing to be done for 'all'` で、古い生成物（`tun`/`tap`）を再コンパイルせずに `install` していた。
  - その結果、no-FPU/no-SSE フラグ未適用の stale バイナリが導入された。
- 併発要因:
  - `e2e-relay.sh` / `e2e-openvpn.sh` の既定 `PPA_INDEX` が `92/90` で、`TUNMAXPPA=20` の範囲外。
  - `tunctl -t tun92` 失敗経路で `tunchmsg` が通り、panic を引き起こしやすい条件になっていた。
- 対処:
  - `e2e-relay.sh` / `e2e-openvpn.sh` の既定 `PPA_INDEX` を `9` に変更。
  - `MAX_PPA_INDEX=19` の上限ガードを追加し、範囲外値は即エラー終了。
  - `tun-test/regression-test.sh` に既定値・上限チェックの静的検証を追加。

## 追加テスト
`tun-test/regression-test.sh` を追加し、今回の修正ポイントに対する静的回帰チェックを実装。

チェック内容:
- 境界チェック修正の残存確認
- `ioctl` ペイロード検証コードの存在確認
- 二重アタッチ防止コードの存在確認
- `DL_BADADDR` / `pullupmsg` ガードの存在確認
- `test.sh` typo 修正確認
- `tunctl.c` のリーク原因ループ除去確認
- `sh -n tun-test/test.sh` 実行
- `configure.in` のカーネル向けレジスタ制約フラグ確認（GCC/Studio）
- `test.sh` の失敗伝播・非対話 sudo・構文検証
- `TUNNEWPPA` のロールバック有無（静的確認）
- `./configure` 実行（`Makefile` 再生成）
- `make` 実行（再試行後に成功）
- `make -C /export/home/kazus/Gits/tuntap tun tap` 実行（成功）
- `make -C /export/home/kazus/Gits/tuntap/tun-test tunrelay` 実行（成功）
- 実機（Solaris 11.4）で `gmake -C tun-test tunrelay` 実行（成功）
- 実機（Solaris 11.4）で `gmake -C tun-test test-regression` 実行（成功）
- 実機（Solaris 11.4）で `fmdump -Vp -u <panic UUID>` により panic stack を確認
- 実機で修正済み `configure` による `KCFLAGS` 再検証（no-FPU/no-SSE フラグ入り）を実施

[07:19:37Z] ASSISTANT FINAL
解析結果です。結論から言うと、今回の panic は tun/tap カーネルモジュール起因です。

• 発生: 2026-03-12 13:35:49 JST
• UUID: 6f01e6d3-ebee-46fe-8bf0-ac6cf2d74e8b
• panic: BAD TRAP: type=7 (#nm Device not available)

根拠:

1. panic スタックが tun:tunchmsg.constprop.0 -> tun:tunwsrv
2. trap 時の CR0 に TS ビットが立っている (...<...,ts,...>)
3. dump 内 RIP (0xfffffffff42a4991) の逆アセンブルで movd %rdx,%xmm0 など SIMD 命令が見える
4. panic 直前に tun/tap 読み込み時の署名検証失敗警告あり
   • WARNING: Signature verification of module /usr/kernel/drv/amd64/tun failed
   • .../tap failed
5. /usr/kernel/drv/amd64/tun と tap は IPS 管理外（pkg contents でヒットなし）かつ署名なし（elfsign verify）

補足:

• 現在の tun/tap は 2026-03-12 14:29:09 JST に再配置されており、panic 時バイナリと一致しない可能性があります。
• ローカルのビルドログでは、再ビルド版は -mno-mmx -mno-sse -mno-sse2 -mno-80387 -msoft-float 付きでビルドされています（tuntap-build-resume.log）。
• 同件の詳細メモも存在します（REVIEW_SOLARIS11.4.md）。

実務的な対処:

1. tun/tap は「no-FPU/no-SSE フラグ付きでクリーン再ビルドした版」のみを導入する。
2. install 前に dis /usr/kernel/drv/amd64/tun | egrep 'xmm|mm[0-7]' が空であることを確認する。
3. 署名なしモジュール運用を続けるなら、導入手順を固定して stale バイナリ混入を防ぐ。

必要なら、このまま再発防止チェック手順をスクリプト化して置きます。
