## Why Allowing a hostname must not bypass deny or review rules on its resolved IP addresses. Forwarding DNS resolution to an upstream proxy also requires checking whether those address restrictions can still be enforced. ## What changed - Add `TcpUpstreamProxy` and `set_tcp_upstream_proxy` to require a configured HTTP `CONNECT` next hop for opaque SOCKS TCP traffic. Wait for a successful response before forwarding payloads and preserve bytes read past the response headers. - Enforce resolved IP deny and review rules at direct connection time, carry destination-scoped authorization through HTTP, SOCKS, and MITM forwarding, and report blocked resolutions as policy denials. - Recognize equivalent numeric IP spellings for restrictive rules. Permit remote TCP DNS only when local binding is allowed and no deny or review pattern can restrict IP addresses; reject upstream proxy loops. - Restrict Linux proxy bridges to managed proxy environment keys and supplied loopback ports. Bound concurrent bridge workers and release them after connection failures while allowing queued responses to drain. - Add test-only Linux DNS name mapping and SOCKS relay helpers with stable synthetic addresses and validation before opening upstream connections. ## Testing Add regression coverage for CONNECT refusal and buffered tunnel data, resolved-address policy denials, approval handling across policy refreshes, equivalent IP literals, DNS mapping stability, rejected relay requests, and bridge cleanup after resets.

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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
The standalone installers download from https://releases.openai.com/codex by default and fall back to GitHub Releases if a metadata or asset download is unavailable. To force GitHub Releases, set CODEX_INSTALLER_USE_RELEASES_OPENAI_COM to false (0 and no are also accepted):
curl -fsSL https://chatgpt.com/codex/install.sh | CODEX_INSTALLER_USE_RELEASES_OPENAI_COM=false sh
$env:CODEX_INSTALLER_USE_RELEASES_OPENAI_COM='false'; irm https://chatgpt.com/codex/install.ps1 | iex
Codex CLI can also be installed via the following package managers:
# 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.
