## Stack 1. Base PR: #18443 stops granting ACLs on `USERPROFILE`. 2. This PR: filters additional SSH-owned profile roots discovered from SSH config. ## Bug The base PR removes the broadest bad grant: `USERPROFILE` itself. That still leaves one important case. A user profile child can be SSH-owned even when its name is not one of our fixed exclusions. For example: ```sshconfig Host devbox IdentityFile ~/.keys/devbox CertificateFile ~/.certs/devbox-cert.pub UserKnownHostsFile ~/.known_hosts_custom Include ~/.ssh/conf.d/*.conf ``` After profile expansion, the sandbox might see these as normal profile children: ```text C:\Users\me\.keys C:\Users\me\.certs C:\Users\me\.known_hosts_custom C:\Users\me\.ssh ``` Those paths have another owner: OpenSSH and the tools that manage SSH identity and host-key state. Codex should not add sandbox ACLs to them. OpenSSH describes this dependency tree in [`ssh_config(5)`](https://man.openbsd.org/ssh_config.5), and the client parser follows the same shape in `readconf.c`: - `Include` recursively reads more config files and expands globs - `IdentityFile` and `CertificateFile` name authentication files - `UserKnownHostsFile`, `GlobalKnownHostsFile`, and `RevokedHostKeys` name host-key files - `ControlPath` and `IdentityAgent` can name profile-owned sockets or control files - these path directives can use forms such as `~`, `%d`, and `${HOME}` ## Change This PR adds a small SSH config dependency scanner. It starts at: ```text ~/.ssh/config ``` Then it returns concrete paths named by `Include` and by path-valued SSH config directives: ```text IdentityFile CertificateFile UserKnownHostsFile GlobalKnownHostsFile RevokedHostKeys ControlPath IdentityAgent ``` For example: ```sshconfig IdentityFile ~/.keys/devbox CertificateFile ~/.certs/devbox-cert.pub Include ~/.ssh/conf.d/*.conf ``` returns paths like: ```text C:\Users\me\.keys\devbox C:\Users\me\.certs\devbox-cert.pub C:\Users\me\.ssh\conf.d\devbox.conf ``` The setup code then maps those paths back to their top-level `USERPROFILE` child and filters matching sandbox roots out of both the writable and readable root lists. ## Why this shape The parser reports what SSH config references. The sandbox setup code decides which `USERPROFILE` roots are unsafe to grant. That keeps the policy simple: 1. expand broad profile grants 2. remove the profile root 3. remove fixed sensitive profile folders 4. remove profile folders referenced by SSH config dependencies If a path has two possible owners, the sandbox steps back. SSH keeps control of SSH config, keys, certificates, known-hosts files, sockets, and included config files. ## Tests - `cargo test -p codex-windows-sandbox --lib` - `just bazel-lock-check` - `just fix -p codex-windows-sandbox` - `git diff --check`
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.
