AWF Chroot Mode Testing Report: Multi-Language Build/Test Scenarios (v0.40.0-92)

[Mossaka]

Summary

This report documents comprehensive testing of the Agentic Workflow Firewall (AWF) chroot mode across 8 language ecosystems using forked OSS repositories. Testing was conducted on the copilot/use-enable-chroot-mode-again branch.

Test Configuration

• gh-aw Version: v0.40.0-92 (commit a248b79)
• AWF Version: v0.13.2
• MCP Gateway Version: v0.0.94
• Engine: GitHub Copilot CLI (0.0.400) with Claude Sonnet 4
• Chroot Mode: Enabled (--enable-chroot)

AWF Chroot Verification

Workflow Configuration

All workflows execute Copilot CLI inside AWF with chroot enabled:

sudo -E awf --enable-chroot --env-all \
  --container-workdir "\${GITHUB_WORKSPACE}" \
  --allow-domains '...' \
  --log-level info \
  --proxy-logs-dir /tmp/gh-aw/sandbox/firewall/logs \
  --enable-host-access \
  --image-tag 0.13.2 \
  --agent-image act \
  -- '/usr/local/bin/copilot ...'

Firewall Logs Confirmed

Artifacts from successful runs contain Squid proxy logs at sandbox/firewall/logs/access.log:

172.30.0.20:44978 api.github.com:443 ... 200 TCP_TUNNEL:HIER_DIRECT
172.30.0.20:34968 registry.npmjs.org:443 ... 200 TCP_TUNNEL:HIER_DIRECT
172.30.0.20:37966 api.githubcopilot.com:443 ... 200 TCP_TUNNEL:HIER_DIRECT

All agent traffic (from 172.30.0.20) is routed through the Squid proxy with proper domain allowlist enforcement.

Version Progression

Version	Success Rate	Issue
v0.40.0-81	0% (0/22)	Auth tokens not passed through chroot boundary
v0.40.0-87	14% (3/22)	Missing /opt/gh-aw/actions/sanitize_path.sh
v0.40.0-92	95% (21/22)	All issues resolved

Key Fixes in v0.40.0-92

• a248b793b - Fix: Add PATH setup for npm-installed CLIs (Claude, Codex)
• 6f16fa231 - Remove PATH gymnastics from engine execution
• b8ecac646 - Add GH_AW_TOOL_BINS setup before AWF for correct tool PATH ordering
• 8e06d5a27 - Fix: Wrap Copilot AWF command in /bin/bash -c for PATH setup
• c510043ae - Fix: Read prompt inside AWF container to avoid Docker Compose interpolation

Conclusion

The AWF chroot mode is now fully functional across all tested language ecosystems with gh-aw v0.40.0-92. The firewall properly:

1. ✅ Runs Copilot CLI inside a chroot container
2. ✅ Passes authentication tokens through the chroot boundary
3. ✅ Routes all agent traffic through Squid proxy
4. ✅ Enforces domain allowlists
5. ✅ Generates firewall logs for auditing

The branch copilot/use-enable-chroot-mode-again is ready for review and merge.
