## Summary - preserve logical symlink paths during permission normalization and config cwd handling - bind real targets for symlinked readable/writable roots in bwrap and remap carveouts and unreadable roots there - add regressions for symlinked carveouts and nested symlink escape masking ## Root cause Permission normalization canonicalized symlinked writable roots and cwd to their real targets too early. That drifted policy checks away from the logical paths the sandboxed process can actually address, while bwrap still needed the real targets for mounts. The mismatch caused shell and apply_patch failures on symlinked writable roots. ## Impact Fixes #15781. Also fixes #17079: - #17079 is the protected symlinked carveout side: bwrap now binds the real symlinked writable-root target and remaps carveouts before masking. Related to #15157: - #15157 is the broader permission-check side of this path-identity problem. This PR addresses the shared logical-vs-canonical normalization issue, but the reported Darwin prompt behavior should be validated separately before auto-closing it. This should also fix #14672, #14694, #14715, and #15725: - #14672, #14694, and #14715 are the same Linux symlinked-writable-root/bwrap family as #15781. - #15725 is the protected symlinked workspace path variant; the PR preserves the protected logical path in policy space while bwrap applies read-only or unreadable treatment to the resolved target so file-vs-directory bind mismatches do not abort sandbox setup. ## Notes - Added Linux-only regressions for symlinked writable ancestors and protected symlinked directory targets, including nested symlink escape masking without rebinding the escape target writable. --------- Co-authored-by: Codex <noreply@openai.com>
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
