## Summary This PR installs a first wave of WFP (Windows Filtering Platform) filters that reduce the surface area of network egress vulnerabilities for the Windows Sandbox. - Add persistent Windows Filtering Platform provider, sublayer, and filters for the Windows sandbox offline account. - Install WFP filters during elevated full setup, log failures non-fatally, and emit setup metrics when analytics are enabled. - Bump the Windows sandbox setup version so existing users rerun full setup and receive the new filters. ## What WFP is Windows Filtering Platform (WFP) is the low-level Windows networking policy engine underneath things like Windows Firewall. It lets privileged code install persistent filtering rules at specific network stack layers, with conditions like "only traffic from this Windows account" or "only this remote port," and an action like block. In this change, we create a Codex-owned persistent WFP provider and sublayer, then install block filters scoped to the Windows sandbox's offline user account via `ALE_USER_ID`. That means the filters are targeted at sandboxed processes running as that account, rather than globally affecting the host. ## Initial filter set We are starting with 12 concrete WFP filters across a few high-value bypass surfaces. The table below describes the filter families rather than one filter per row: | Area | Concrete filters | Purpose | | --- | --- | --- | | ICMP | 4 filters: ICMP v4/v6 on `ALE_AUTH_CONNECT` and `ALE_RESOURCE_ASSIGNMENT` | Block direct ping-style network reachability checks from the offline account. | | DNS | 2 filters: remote port `53` on `ALE_AUTH_CONNECT_V4/V6` | Block direct DNS queries that bypass our intended proxy/offline path. | | DNS-over-TLS | 2 filters: remote port `853` on `ALE_AUTH_CONNECT_V4/V6` | Block encrypted DNS attempts that could bypass ordinary DNS interception. | | SMB / NetBIOS | 4 filters: remote ports `445` and `139` on `ALE_AUTH_CONNECT_V4/V6` | Block Windows file-sharing/network share traffic from sandboxed processes. | For IPv4/IPv6 coverage, the port-based filters are installed on both `ALE_AUTH_CONNECT_V4` and `ALE_AUTH_CONNECT_V6`. ICMP also gets both connect-layer and resource-assignment-layer coverage because ICMP traffic is shaped differently from ordinary TCP/UDP port traffic. ## Validation - `cargo fmt -p codex-windows-sandbox` (completed with existing stable-rustfmt warnings about `imports_granularity = Item`) - `cargo test -p codex-windows-sandbox wfp::tests` - `cargo test -p codex-windows-sandbox` (fails in existing legacy PowerShell sandbox tests because `Microsoft.PowerShell.Utility` could not be loaded; WFP tests passed before that failure)

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.
