Operators who cannot sign in currently cannot use the dashboard updater. Add meshpanel update [-c config.yaml] [--check] to check for or stage a signed release from the CLI.

The command reuses the existing signature/checksum verification, respects update configuration, and considers a verified staged version when the installed launcher is older. After a successful download it prints the systemd restart command. Documentation shows execution as the service user to preserve staging-file ownership and explains the initial manual upgrade needed for older binaries.

Validation: go test ./cmd/meshpanel ./internal/update ./internal/web ./internal/auth passed. CLI tests cover check-only behavior, installation, no downgrade, lookup and verification errors, and argument handling.

Summary by CodeRabbit

• New Features
  • Added a CLI command to check for available releases or download and verify a newer release for staging.
  • Check-only mode reports whether an update is available without staging it. The command respects update settings and avoids downgrading to an older release.
  • Staged updates do not restart the service; restart it manually to apply the update.
  • Added setup guidance for running update checks and staging installs from the command line, including options for older launchers. Updates require an absolute database path.

- Line 75: In the test containing t.Chdir, clear the inherited
MESHPANEL_HEADSCALE_API_KEY_PATH, MESHPANEL_SERVER_SESSION_SECRET_PATH, and
MESHPANEL_TELEGRAM_TOKEN_PATH overrides before calling runUpdate. Ensure they
are absent, not merely empty, during the test, and use test-scoped environment
cleanup so the process environment is restored afterward.

Review comments at @README.md:
- Line 192: Update the staging-directory guidance near the absolute `db.path`
instruction to clarify that when the service uses `MESHPANEL_*` environment
overrides, the CLI must receive the same effective overrides so both processes
use the same staging directory.

Walkthrough

The CLI now supports an update command to check for newer releases or stage a newer release without restarting the service. The README documents command use, restart steps, and alternatives for launchers without the command. The direct Tailscale dependency changes to v1.104.4.

Merge Risk: Low · up to 384fe

The update command is broadly mergeable, but matching effective service overrides and clearing inherited secret-path variables would prevent operational confusion and test failures.

Security architecture risk: Low · up to 384fe

The command preserves signed-download verification and startup verification, and activation still requires a service restart. No new executable-authenticity or authorization bypass was established. Remaining uncertainty concerns shared staging, recovery, and whether deployed configuration and permissions match the documented operating procedure.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The intended activation scope is one configured service instance and its database-adjacent update directory. Activation inherits that service’s identity and access, including the shipped headscale supplementary group and writable paths. The CLI adds local invocation, not a network listener or cross-host deployment mechanism.

Trust Boundaries and Controls

• observed — The web update path requires owner permission. The new CLI instead relies on local OS authority and filesystem access to stage files, while preserving artifact verification. The shipped state-directory permissions and documented service-user invocation support this intentional boundary; actual deployment permissions remain unverified.
• observed — The URL-policy proof gap is resolved for the inspected caller. Initial downloads and redirects require HTTPS on github.com, api.github.com, or a githubusercontent.com subdomain. Release metadata must describe a final, parseable version, and executable authenticity is separately checked against the embedded release key.

Resilience and Maintainability Implications

• inferred — An absolute database path prevents working-directory-dependent staging, but does not prove that CLI and service configurations identify the same directory. Configuration loading applies environment overrides in both paths. Production configuration parity therefore remains an operational assumption, not an enforced invariant.

Hardening Proposals

• proposed — As follow-up hardening of the existing updater, publish immutable release generations through one atomic activation reference, serialize staging and cleanup across processes, and bind version identity to the authenticated generation. This would improve interrupted-update recovery without treating the inherited behavior as a newly introduced finding.

Full details: Title check

Explanation

The title "feat: support signed updates from the CLI" matches the main change. The PR adds a meshpanel update CLI command (with --check) that installs verified releases. The changeset includes the update.go command, its tests, usage text in main.go, and README documentation. The title names the primary feature and the verification aspect, and it uses a conventional commit prefix. Its scope is accurate, so it does not need a file list or extra detail.

Clear inherited secret-file overrides in this test.

runUpdate calls config.Load before it checks for an absolute db.path. Load reads any MESHPANEL_*_PATH secret file that the process environment sets. A relative value resolves against the temporary directory after t.Chdir. The read can then fail first, so the test does not reach the assertion it checks.

Document the effective environment requirement.

The shipped service and CLI use the same config file, but MESHPANEL_DB_PATH overrides db.path after YAML loading. If the service uses environment overrides, pass the same effective overrides to the CLI so both processes use the same staging directory.
