Cloud VMs: private per-user Freestyle VPC + WireGuard tunnel from the cmux app - #11602
Conversation
One VPC per (user, provider), provisioned idempotently on first machine create and recorded in cloud_vm_networks. New Freestyle machines join it, state outbound-only firewall rules (no public inbound port at all), and attach at their private VPC address: ws://[<vpc ipv6>]:1337/v1/link. The VPC's single members-reach-each-other rule is what admits the owner's other machines and WireGuard tunnels to the daemon port. The user's computers join the same network over WireGuard tunnels minted at POST /api/vm/tunnel: the client generates the keypair and sends only the public half, so the backend never sees a private key. Enrollment is idempotent per device fingerprint; a mismatched key rotates the tunnel in place, keeping the device's address on the network. Tunnels and the network are deleted on account deletion after the machines are destroyed. CMUX_VM_PRIVATE_NETWORK_ENABLED=0 is the complete rollback: later creates revert to the public-IPv6 posture, and existing machines keep working either way because reachability is resolved per machine from the addresses it actually holds. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The app owns this Mac's membership in the user's private Cloud VM network: VMTunnelManager mints a Curve25519 keypair (private half never leaves ~/.cmuxterm/wireguard, 0600) and a stable device fingerprint, enrolls idempotently through POST /api/vm/tunnel, and writes the completed wg-quick config to ~/.cmuxterm/wireguard/cmux.conf. Bring-up is `cmux vpn up|down|status|revoke` over the new vm.tunnel_config/status/revoke socket verbs. up runs sudo wg-quick against the app-written config — sudo in the user's terminal is the honest privilege prompt while the NetworkExtension entitlement is pending. The entitlement path is gated at runtime (VMTunnelManager.networkExtensionAvailable, advertised to the CLI as network_extension_available), so a build signed with the packet-tunnel entitlement later steers cmux vpn to an app-managed tunnel with no CLI release. User-facing strings are localized (en/ja) and the tunnel-manager tests are wired into the test target. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Foundation's Process detaches its child into a new process group, so the sudo wg-quick that cmux vpn up spawns was stopped with SIGTTIN the moment it read the tty for a password, and the command hung silently. Foreground the child's group for its lifetime (waking it with SIGCONT if it already stopped) and restore the caller's group after — the same dance the feed TUI does for its interactive subprocess. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…file /var/run/wireguard/<name>.name is root-only (0400) on macOS, so the status check read "down" while the tunnel was up. Ask the question the network can answer without privileges instead: does any interface hold one of the tunnel's own [Interface] Addresses from the config we wrote? Those are fixed platform-side addresses unique to the tunnel, so a match is the tunnel and nothing else. AllowedIPs ranges are deliberately never matched — any 10.x interface would read as "up". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Base open/reset/reopen created machines through finishBaseCreate, which skipped the private-network placement createVm got — so the first machine most users touch was the only publicly exposed one, and on a Mac without public IPv6 its daemon was unreachable outright. Resolve the owner's network there too (services handed in explicitly: finishBaseCreate takes its dependencies as parameters, so the context-reading resolver gets them provided rather than widening the function's environment). The stats poll answered a retryable 502 on providers without getStats, so the activity panel polled forever. Throw the typed unsupported error so the route answers 501 and clients stop. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A machine destroyed mid-setup left the approve poll running until its
5-minute deadline, flooding the control plane with 404s — the machine
cannot come back under that id, so a 404 ends the loop.
The remove-blaxel migration compared enum literals ('blaxel') that a
fresh-database replay rejects with "unsafe use of new value" (the value
was added earlier in the same migration batch). Compare as text instead:
equivalent, and replay-safe.

📝 WalkthroughWalkthroughChangesPrivate VM networking now uses per-owner VPCs and WireGuard tunnels. The change adds provider, database, workflow, API, macOS, and CLI support, plus account-deletion cleanup and tests. Private VM networking
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The PR moves VM access behind private VPCs and WireGuard tunnels, but the current implementation has security and availability issues that should be fixed before merge: tunnel deletion may not identify the device being revoked, concurrent enrollment can leave provider tunnels untracked, and account deletion can partially remove access while restoring the account.

invoke its lifecycle up command and avoid the wg-quick lookup; otherwise
preserve the existing wg-quick path. Ensure the advertised handoff contract

underlying launch failure details in the FileHandle.standardError message.
- Line 59: Update the VPN CLI localization in the surrounding VPN command flow
to resolve the “cli.vpn.alreadyUp” key through

CMUXDiffViewerLocalization pattern, instead of using the standalone CLI’s
default String(localized:defaultValue:) lookup.
In `@Sources/Cloud/VMClient.swift`:
- Line 982: Update request to accept queryItems and assign them to
URLComponents.queryItems rather than embedding the query string in path. In the
tunnel revocation call, pass the plain /api/vm/tunnel path and provide
deviceFingerprint as a query item so the DELETE request includes it.
In `@Sources/Cloud/VMClientSocketCommands.swift`:
- Line 251: Replace the deviceFingerprint() calls in the status and revoke
handling with a non-mutating stored-fingerprint lookup, ensuring these commands
never create or persist a device identity. Keep identity minting exclusively in
enroll, and return the established explicit not-enrolled result or documented
no-op when no stored fingerprint exists.
- Line 269: Update the cleanup path in VMClientSocketCommands to propagate
failures from FileManager.removeItem after successful server revocation, while
treating an already-missing config as successful. Replace the silent try?
handling so callers can distinguish removal errors from a completed local
cleanup.
In `@web/app/api/account/route.ts`:
- Around line 298-304: Update the private-network cleanup flow around
deletePrivateNetworkingForAccountDeletion to report destructive progress through
a per-deletion progress callback, matching the existing afterVmDestroy pattern.
Set destructiveCleanupStarted when a tunnel or network deletion actually

private-network path consistently uses the VPC IPv6 address, while the stable

Resolve VPN CLI strings from the enclosing app bundle.
The standalone CLI has no string catalog. Direct String(localized:defaultValue:) calls therefore use their English defaults. Route the VPN keys through CLIExecutableLocator.enclosingAppBundle(startingAt:), as CMUXDiffViewerLocalization does.

Implement the advertised NetworkExtension handoff.
When the tunnel is down, this branch always requires wg-quick. runVPNUp never reads network_extension_available or invokes an app-managed lifecycle command. An entitled build therefore fails if wg-quick is absent, despite the contract in lines 17-21.
Add the app-managed up path before this lookup, or remove the advertised handoff until that socket command exists.

Preserve the process-launch error description.
Replace error.localizedDescription with String(describing: error). localizedDescription can reduce non-LocalizedError failures to a generic message and hide the launch failure cause.
Based on learnings: CLI error formatting must use String(describing: error) rather than error.localizedDescription.

Pass the device fingerprint as query items.
components.string contains ?deviceFingerprint=..., but request assigns this value to URLComponents.path. The query separator is encoded as path data. The DELETE request does not send deviceFingerprint, so tunnel revocation cannot identify the device.
Add a queryItems parameter to request, assign it to url.queryItems, and call it with the plain /api/vm/tunnel path.

Do not mint a device identity during status or revoke.
deviceFingerprint() creates and writes device-id when no identity exists. Therefore vm.tunnel_status is not read-only, and vm.tunnel_revoke on a fresh install sends a delete request for an identity that was never enrolled.
Add a non-mutating stored-fingerprint lookup. Use minting only from enroll. If no stored identity exists, return an explicit not-enrolled result or documented no-op.

Align the Freestyle route descriptions.
This section says that default Freestyle machines use a private VPC address with no public inbound port. Lines 391-398 still state that Freestyle uses the stable public IPv6 route. Following that route for a default-created machine can make attach fail because the public port is closed. Update both sections to distinguish private-network machines from legacy machines or creates with CMUX_VM_PRIVATE_NETWORK_ENABLED=0.

Serialize first-time tunnel enrollment.
Two concurrent requests can both find no active row, create provider tunnels, and reach this unconditional insert. The unique index then rejects one request. If both provider creates succeed, the rejected request leaves an untracked provider tunnel.
Serialize findTunnel → provider creation → insertTunnel per (userId, deviceFingerprint), or use a provider idempotency operation with conflict recovery and cleanup. Do not resolve this only with an upsert because that can replace the tracked provider tunnel ID.

Add a failure case for private-network cleanup.
The mock always succeeds and always reports { tunnels: 0, networks: 0 }. No test covers a throwing deletePrivateNetworking program, so the route's failure classification for this step is untested. That is the exact path flagged in web/app/api/account/route.ts Lines 298-304.
Add a test that makes this program throw and asserts the response is account_delete_retryable with the partial-cleanup log label.

Assert the cross-service call order.
This test only proves that deleteTunnel and revokeTunnel both ran. It passes if a regression revokes the database row before provider deletion. Record both calls in one shared sequence and assert deleteTunnel precedes revokeTunnel.

Cloud VMs no longer expose any public port. Every Freestyle machine joins the one private VPC that belongs to its owner, and the owner's computers join the same VPC over WireGuard tunnels that the cmux app sets up — so the cmux-tui daemon is reachable only from the owner's own machines and computers.
