From 678ba25dfdcdf31221bb333fb1b77deb24a4b71d Mon Sep 17 00:00:00 2001 From: Yuriy Andamasov Date: Sun, 10 May 2026 22:02:09 +0300 Subject: ci: AI Validation rewrite — MyST + split-job + branch map MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rewrites .github/workflows/ai-validation.yml to align with the docs current→rolling rename and the RST→MyST migration. The body is a byte-for-byte copy of the canonical reference at VyOS-Networks/vyos-docs-opus-reviewer/scripts/ai-validation.yml at tag reviewer-v1.0.0 (header stripped on copy). Key changes vs the previously deployed (and currently disabled) workflow: - Trigger pull_request → pull_request_target (required for fork PRs to access secrets) with a split prepare/validate job pattern that preserves the trust boundary. - prepare job: NO secrets referenced; checks out the PR merge ref with persist-credentials:false; emits NUL-delimited diffs + bundles changed .md files into _changed_md/ via xargs cp. - validate job: secrets-availability check; sparse-checkout of branches.json from the reviewer repo (pinned via REVIEWER_REF env var, default reviewer-v1.0.0); fail-fast resolution of docs branch → vyos-1x branch via jq lookup; mapped vyos-1x checkout; reference-DB download (best-effort); fail-closed gate when MyST files are in the diff but the DB is missing; Pass 1 runs from inside _changed_md/ so diff-relative paths resolve; Pass 2 via claude-code-action with hardened prompt (untrusted-content ringfence, narrow tool allowlist). - Concurrency: PR-scoped concurrency cancels superseded runs. - Runners: [self-hosted, web] (org-level VyOS runner pool). - Action versions bumped for Node-24 compat: - actions/create-github-app-token@v2 - actions/setup-python@v6 - robinraju/release-downloader@ Required secrets in vyos/vyos-documentation: ANTHROPIC_API_KEY, VYOS_APP_ID, VYOS_APP_PRIVATE_KEY Implements: - VyOS-Networks/vyos-docs-opus-reviewer docs/superpowers/specs/2026-05-10-myst-parser-and-workflow-fix-design.md Workflow remains disabled_manually while this PR is in review.

Added `--diff-filter=ACMRT` to both name-only diffs so deletions are excluded from the cp source list. Deletions still appear in diff-md.patch (which uses the unfiltered full diff) so Pass 1's --pr-diff input still sees them via the patch hunk. 2. line 103 (reviewer sparse-checkout): The App token was being persisted into reviewer/.git/config as an http extraheader by default. The Pass 2 claude-code-action step has Read/Glob/Grep allowed, so a prompt-injection attempt could exfiltrate the token from the workspace. Added `persist-credentials: false`. The sparse-checkout fetched only branches.json which is a one-shot read, no further git ops needed in this job. 3. line 127 (vyos-1x checkout): Same persist-credentials concern. The vyos-1x clone is read by claude-code-action for Pass 2 source inspection — exactly the step where filesystem read tools are exposed to LLM-driven shell behavior. Added `persist-credentials: false`. The vyos-1x tree is only read after this checkout (`Read,Glob,Grep` over `.vyos-1x/`); we don't run any git commands against it that would need the token. Suppressed-by-Copilot finding (line 64, id-token: write): Pushback. claude-code-action@v1 uses OIDC internally (verified by commit b18a399c on the previously-deployed workflow).

The previous `xargs cp` would follow the symlink and copy the *target's* content (/etc/passwd, runner secrets, ssh keys, the App's PEM if accessible) into the pr-input artifact. The validate job downloads that artifact and exposes it to the Pass 2 claude-code-action step (which has Read,Glob,Grep tools), so a prompt-injection attempt could exfiltrate runner state via inline review comments. Mitigation: replace the cp loop with `git show HEAD:` extraction. This pulls bytes directly from the merge commit's tree blob. For a symlink entry, git show returns the textual target path (a string like "/etc/passwd"), NOT the target's filesystem content. The artifact's worst-case is a text file containing a path string, which has no exfiltration value. Implementation: - Read NUL-delimited paths from changed-md.z (preserves filename safety). - For each path, check ls-tree mode: 100644/100755 = normal file, accept; 120000 = symlink, skip with ::warning::; 160000 = submodule, skip; anything else, skip. - Use `git show HEAD:` to write blob content into _changed_md/. - All variable expansions are within double-quotes (no word-splitting, no glob, no recursive parse of $() in the substituted value). The xargs cp option-injection defense (`-- ` end-of-options) is no longer needed since cp is gone. The --diff-filter=ACMRT and persist-credentials fixes from edd903d remain. Suppressed-by-Copilot finding (line 68, id-token: write): Same as previous round — pushback. claude-code-action@v1 uses OIDC internally (verified via vyos/vyos-documentation commit b18a399c, where the permission was removed and immediately restored after the action broke).

Copilot — line 59, mkdir collision after cancellation: `mkdir _changed_md` fails with EEXIST if the directory was left behind by a previous run that concurrency.cancel-in-progress killed before the post-job cleanup step could execute. On a busy PR with rapid synchronize events this is a real non-determinism. Replaced with `rm -rf _changed_md && mkdir -p` so the bundling step is idempotent. 2. CodeRabbit — Major, scripts/ai-validation.yml:244 (mirrored here on the deployed copy): `uv pip install "git+https://x-access-token:${TOKEN}@..."` puts the App token in process argv. On a self-hosted runner anyone able to read /proc//cmdline (any user with the same UID, any root tool, any LSM audit log) sees the secret while uv/git is running. This undercuts the persist-credentials:false hardening on the surrounding checkouts. Replaced the install with a two-step checkout + local-path install: - actions/checkout@v6 with persist-credentials:false fetches the reviewer source into ./reviewer-src using the App token as a transient http extraheader (not argv). - `uv pip install ./reviewer-src` then installs from the local path — no token anywhere on the command line. Net trust boundary: same security posture as the existing sparse-checkout of branches.json (line 100-110); no new attack surface. 🤖 Generated by [robots](https://vyos.io) --- .github/workflows/ai-validation.yml | 28 +++++++++++++++++++++++++--- 1 file changed, 25 insertions(+), 3 deletions(-) (limited to '.github/workflows') diff --git a/.github/workflows/ai-validation.yml b/.github/workflows/ai-validation.yml index 9820f7d4..e93dc886 100644 --- a/.github/workflows/ai-validation.yml +++ b/.github/workflows/ai-validation.yml @@ -56,7 +56,11 @@ jobs: # input. `git show HEAD:` returns the blob directly from the # object database; for a symlink-mode entry it returns the textual # target path, never the target's content. - mkdir _changed_md + # Idempotent: a previous run cancelled by concurrency.cancel-in-progress + # may have left _changed_md/ behind on the self-hosted runner if the + # job was killed before the post-job cleanup ran. rm -rf + mkdir -p + # guarantees a clean target regardless of prior state. + rm -rf _changed_md && mkdir -p _changed_md while IFS= read -r -d '' path; do # Path-traversal hardening: even though git's tree machinery # rejects `..` segments and absolute paths in committed entries @@ -225,10 +229,28 @@ jobs: python-version: '3.12' activate-environment: true - - name: Install reviewer (pinned to REVIEWER_REF) + # Check out the reviewer source instead of installing via + # `uv pip install git+https://x-access-token:@...` — the URL form + # puts the App token in process argv (visible through + # /proc//cmdline on the self-hosted runner while uv or git is + # running). actions/checkout writes the token as a transient http + # extraheader instead, and persist-credentials:false ensures it does + # not linger in reviewer-src/.git/config where the Pass 2 LLM step + # could read it. + - name: Checkout reviewer package source (pinned to REVIEWER_REF) + if: steps.secrets-check.outputs.skip != 'true' + uses: actions/checkout@v6 + with: + repository: VyOS-Networks/vyos-docs-opus-reviewer + ref: ${{ env.REVIEWER_REF }} + token: ${{ steps.app.outputs.token }} + persist-credentials: false + path: reviewer-src + + - name: Install reviewer (from local checkout) if: steps.secrets-check.outputs.skip != 'true' run: | - uv pip install "git+https://x-access-token:${{ steps.app.outputs.token }}@github.com/VyOS-Networks/vyos-docs-opus-reviewer.git@${{ env.REVIEWER_REF }}" + uv pip install ./reviewer-src # Run from inside _changed_md/ so the diff's relative paths # (`docs/...`) resolve to actual files in the artifact tree. -- cgit v1.2.3 From b0fdd079b2d8ebe41a9da436a55f89c1be0dbbbc Mon Sep 17 00:00:00 2001 From: Yuriy Andamasov Date: Sun, 10 May 2026 22:53:37 +0300 Subject: fix(ci): fail-fast on non-regular docs entries in PR diff MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Copilot finding on .github/workflows/ai-validation.yml:86: The bundling loop currently *skips* non-regular tree entries (symlinks mode 120000, submodules 160000) with a `::warning::` and continues. A PR that converts a regular docs/**/*.md into a symlink effectively bypasses both Pass 1 (no file copied into _changed_md/) and Pass 2 (LLM Read/Glob/Grep sees no content) — reducing validation coverage on exactly the kind of change that warrants closer review. Replaced the `continue` with `exit 1` on non-regular mode. The error message instructs the PR author to convert the file back to a regular .md (or get explicit maintainer waiver). Maintainers can still land non-regular doc entries by adjusting the workflow, but the decision becomes visible rather than silent. Combined with the symlink-exfil mitigation (commit 1ea164ff): we no longer copy symlink target content into the artifact AND we no longer silently skip the change. Either it's a regular file we can validate, or the workflow fails loudly. Same change being applied to the canonical reference copy in VyOS-Networks/vyos-docs-opus-reviewer PR #13.

CRITICAL — line 281, model: input is silently ignored. anthropics/claude-code-action@v1 removed the top-level `model` input; the migration guide says model selection now travels via `claude_args: --model `. With the old form, the action used its DEFAULT model on every run instead of the pinned claude-opus-4-7, defeating the version pin entirely. CR even ran a web query and actionlint to verify (actionlint output: "input 'model' is not defined in action 'anthropics/claude-code-action@v1'"). Moved --model claude-opus-4-7 into claude_args. 2. MAJOR — line 135, secrets template-expanded into shell text. `[ -z "${{ secrets.VYOS_APP_ID }}" ]` lets GH Actions do ${{ ... }} expansion BEFORE bash parses the script. A secret containing a single quote, backtick, or $ would either break the test syntactically or be evaluated by the shell. The same hygiene that justifies the prepare/validate split applies here. Moved the three secrets to an env: mapping; the script now reads "$VYOS_APP_ID" etc., handed to bash as already-quoted env vars. 3. NIT — line 7, concurrency group brittle outside PR events. `github.event.pull_request.number` is empty on workflow_dispatch or schedule; the group would collapse to "ai-validation-" and unrelated runs cancel each other. Defensive fix: fallback to `github.ref`. Today the workflow only fires on pull_request_target so this is purely future-proofing.

Even though the prepare job doesn't execute fork code (it only does git diff / git show / file reads — never pip install, npm install, build, or tests), Copilot's right that running fork content on a self-hosted runner with internal-network access is the wrong default. A future maintainer who innocently adds a "run linter" step to prepare could turn it into an attack vector against the VyOS internal network or a persistence mechanism on the host. Moved prepare to runs-on: ubuntu-latest. GitHub-hosted runners are ephemeral, isolated, and have no path to internal services. The trusted validate job stays on [self-hosted, web]; the split-job artifact bridges the trust boundary as before. Side benefit: removes the runner-side dependency on jq/gh/git for the prepare job (those are pre-installed on ubuntu-latest). 2. line 149 — skip-notice discoverability. When secrets are missing the workflow only emits ::notice:: in the run logs. Contributors checking the PR timeline have no reason to click through to the run page.

The runner pool is Debian 12 self-hosted (web-runner-01, web-runner-02). prepare must run there too. Pushing back on Copilot's defense-in-depth finding (line 35) with explicit threat-model reasoning documented in the workflow comment: - prepare does not execute fork code. Only git fetch / git diff / git show / file reads. No pip install, no npm install, no build, no test. Adding any of these would require a deliberate code change in this file that a reviewer must approve. - No secrets are referenced in prepare. Even a presence-check would leak the value into the runner environment. - persist-credentials: false on the merge-ref checkout keeps the default GITHUB_TOKEN out of fork-readable .git/config. - The atos-actions/clean-self-hosted-runner step (`if: always()`) wipes the workspace after every job regardless of exit state. The split-job artifact still bridges the trust boundary to validate. validate remains the only place where secrets are referenced. The skip-notice `gh pr comment` step from a22df7d is preserved — that's an independent discoverability improvement. 🤖 Generated by [robots](https://vyos.io) --- .github/workflows/ai-validation.yml | 31 +++++++++++++++++++++---------- 1 file changed, 21 insertions(+), 10 deletions(-) (limited to '.github/workflows') diff --git a/.github/workflows/ai-validation.yml b/.github/workflows/ai-validation.yml index 5d1ecf2b..19ebd9f6 100644 --- a/.github/workflows/ai-validation.yml +++ b/.github/workflows/ai-validation.yml @@ -25,17 +25,28 @@ jobs: # expanding the attack surface to any future shell change in this job. # The validate job below performs the secrets-availability check and # skips with a notice if any are missing. - # Untrusted prepare runs on GitHub-hosted ubuntu-latest, NOT the - # self-hosted web pool.
