# Current Task (2025-11-06)
|
||||
|
||||
## 🎉 デバッグ完了 (2025-11-07)
|
||||
|
||||
結論
|
||||
- HAKMEM allocator は ASan / UBSan で健全性を確認済み。メモリ破壊や未定義動作は検出されず、現状の箱境界は安全に動作。
|
||||
|
||||
検証ルート（便利ターゲット）
|
||||
- ✅ `make asan-preload-run THREADS=4` — メモリ破壊チェック（安定; 非ASan本体+LD_PRELOADでASan先頭）
|
||||
- ✅ `make ubsan-mailbox-run THREADS=4` — Mailbox/Remote 健全性チェック（安定）
|
||||
- ✅ `make asan-preload-mailbox-lite THREADS=4` — 短時間の境界チェック（安定, 5s/CHPT=256, RemoteGuard+Ring）
|
||||
|
||||
補足（運用ガイド）
|
||||
- ASan直リンクの4Tは環境依存で Shadow 予約に失敗するため、当面は PRELOAD 方式を既定とし、Mailbox 有効系は UBSan を用いる。
|
||||
- CI/スクリプトは上記ターゲットを用いることで再起動ループの回避と安定検証が可能。
|
||||
|
||||
## 🆘 最優先: 強制終了/再起動ループの緊急対応（sanitizer/環境周り）
|
||||
|
||||
現象
|
||||
- ベンチ実行や補助プロセス実行中に強制終了（SIGKILL/abort）し、環境全体が再起動ループに入ることがある。
|
||||
- ASan直リンク（`larson_hakmem_asan{,_alloc}`）の4T実行で高頻度に `ReserveShadowMemoryRange failed (ENOMEM)` が発生。
|
||||
- Ready/Mailbox ON + ASan ではプロセスが沈黙/強制終了するケースあり（stderr/outとも0バイト）。
|
||||
|
||||
暫定診断（根本原因候補）
|
||||
- AddressSanitizer の Shadow メモリ確保が他領域と衝突し ENOMEM → ランタイムが abort。
|
||||
- LD_PRELOAD順序/ASLR/マップ数制限（`vm.max_map_count`）/LTO+最適化との相性で、MT下の Shadow 予約が不安定化。
|
||||
- Ready/Mailbox ON でメモリマップ挙動が変化し、ASan の reserve 失敗トリガを踏みやすい。
|
||||
|
||||
安全な回避経路（検証済み）
|
||||
- ASan: 本体は非ASan（`larson_system`）、`LD_PRELOAD=$(gcc -print-file-name=libasan.so):./libhakmem_asan.so` でランタイム先頭ロード。
|
||||
- 4T 安定完走（Ready/Mailbox OFF）: ~3.25M ops/s を確認。
|
||||
- UBSan: `make ubsan-larson-alloc` + Ready/Mailbox ON で 4T 完走（~3.35M ops/s）。
|
||||
|
||||
緊急対応の優先順位（Fail‑Safe）
|
||||
1) 既定の「計測/検証」ルートを sanitizer-safe に切替（当面の安定化）
|
||||
- ASanが必要: `scripts/run_larson_asan_preload.sh 4`（Ready/Mailbox OFF）
|
||||
- Ready/Mailbox ON検証: UBSanに切替 `HAKMEM_WRAP_TINY=1 HAKMEM_TINY_SS_ADOPT=1 ./larson_hakmem_ubsan_alloc …`
|
||||
2) 再起動ループ回避の運用ガード
|
||||
- 長時間ASan 4T禁止、まず短時間/小負荷（例: ch/thread 256, sleep 5）で段階実行。
|
||||
- CI/スクリプトで ASan 直リンク4Tをスキップし、LD_PRELOAD 方式へ統一。
|
||||
3) 根治（後追い・環境依存）
|
||||
- オプション: `ASAN_OPTIONS=quarantine_size_mb=8:malloc_context_size=5` 等でメモリ圧縮（効果限定的）。
|
||||
- `vm.max_map_count` 引き上げ、ASLR制御、最適化/LTO無効化（要環境合意）。
|
||||
|
||||
当面の実行手順（コピペ可）
|
||||
```
|
||||
# ASan（Ready/Mailbox OFF, 4T安定）
|
||||
./scripts/run_larson_asan_preload.sh 4
|
||||
|
||||
# UBSan（Ready/Mailbox ON, 4T安定）
|
||||
make -j ubsan-larson-alloc >/dev/null
|
||||
HAKMEM_WRAP_TINY=1 HAKMEM_TINY_SS_ADOPT=1 ./larson_hakmem_ubsan_alloc 10 8 128 1024 1 12345 4
|
||||
```
|
||||
|
||||
チェックリスト（PR/レビュー時）
|
||||
- [ ] ASan直リンク4Tを実行していない（PRELOAD方式へ誘導）。
|
||||
- [ ] Ready/Mailbox ON の4Tは UBSan で計測している。
|
||||
- [ ] ベンチスクリプトで異常終了時に即時中断しループしない。
|
||||
- [ ] 影響範囲のログ（ワンショット/リング）を残すが常時多出力は避ける。
