Refactor cage_map to allow concurrent access by Yaxuan-w · Pull Request #1156 · Lind-Project/lind-wasm

Yaxuan-w · 2026-05-04T14:42:16Z

Resolves #1050

This PR replaces the unsynchronized mutable slot with ArcSwapOption<Cage>, so each cage table entry can be atomically loaded, replaced, or cleared. This removes the data race between concurrent lookup and removal while preserving O(1) indexed lookup by cage ID.

Performance Impact

This change does introduce measurable overhead on lightweight metadata syscall paths where cage lookup dominates the operation cost. The overhead is most visible in very lightweight syscalls such as getpid(), getppid(), getuid(), and geteuid(), because these calls do little work besides runtime metadata lookup.

The fork + waitpid lifecycle benchmark does not show a measurable regression.

Future Optimization

There is still room to optimize cage lookup after the remaining exit-handling issues #1072 are resolved. In particular, once we can guarantee cage lifetime through 3i. For example, by ensuring that a cage cannot be removed while a grate dispatch or syscall path is still using it, we may be able to optimize hot-path lookup further.
