This is a major redesign of how sandbox configuration works and aims to fix https://github.com/openai/codex/issues/1248. Specifically, it replaces `sandbox_permissions` in `config.toml` (and the `-s`/`--sandbox-permission` CLI flags) with a "table" with effectively three variants: ```toml # Safest option: full disk is read-only, but writes and network access are disallowed. [sandbox] mode = "read-only" # The cwd of the Codex task is writable, as well as $TMPDIR on macOS. # writable_roots can be used to specify additional writable folders. [sandbox] mode = "workspace-write" writable_roots = [] # Optional, defaults to the empty list. network_access = false # Optional, defaults to false. # Disable sandboxing: use at your own risk!!! [sandbox] mode = "danger-full-access" ``` This should make sandboxing easier to reason about. While we have dropped support for `-s`, the way it works now is: - no flags => `read-only` - `--full-auto` => `workspace-write` - currently, there is no way to specify `danger-full-access` via a CLI flag, but we will revisit that as part of https://github.com/openai/codex/issues/1254 Outstanding issue: - As noted in the `TODO` on `SandboxPolicy::is_unrestricted()`, we are still conflating sandbox preferences with approval preferences in that case, which needs to be cleaned up.
codex-linux-sandbox
This crate is responsible for producing:
- a
codex-linux-sandboxstandalone executable for Linux that is bundled with the Node.js version of the Codex CLI - a lib crate that exposes the business logic of the executable as
run_main()so that- the
codex-execCLI can check if its arg0 iscodex-linux-sandboxand, if so, execute as if it werecodex-linux-sandbox - this should also be true of the
codexmultitool CLI
- the
