From 1a1caca99dbda5c28c557e11084501dc94a63516 Mon Sep 17 00:00:00 2001 From: Raghav Pillai <me@raghav.sh> Date: Mon, 23 Feb 2026 18:24:14 +0200 Subject: [PATCH 16/59] Add cmux CLI relay and tests - Introduce CLI client (cmux) to relay v1 text and v2 JSON-RPC commands over Unix/TCP sockets - Implement command specs, flag parsing, v1/v2 round-trips, TCP retry with address refresh - Add browser subcommand mapping and rpc passthrough support - Support busybox-style invocation when argv[0]=="cmux" and add 'cli' subcommand - Add comprehensive unit tests for socket dialing, CLI commands, flag-to-param mapping, and env defaults - Add socket_addr file fallback reader and random request id generation --- daemon/remote/cmd/cmuxd-remote/cli.go | 530 +++++++++++++++++++++

18700b0515fedb515f05345e86bf47750b667fe2 Mon Sep 17 00:00:00 2001 From: Raghav Pillai <me@raghav.sh> Date: Mon, 23 Feb 2026 18:24:25 +0200 Subject: [PATCH 17/59] Add SSH reverse relay for local Unix socket - Add support for spawning an SSH reverse relay that forwards a remote TCP port to a local cmux Unix socket - Generate random ephemeral relay port and propagate via CLI, workspace config, and JSON payloads - Start/monitor background relay Process in WorkspaceRemoteSessionController with stderr handling and auto-restart - Filter probe-reported ephemeral ports and avoid treating relay ports as user service ports - Create remote cmux symlink and write remote ~/.cmux/socket_addr for relay discovery - Kill orphaned relay processes on startup to avoid conflicts - Add helpers to check loopback port reachability and adjust forward/SSH options (ControlPath, ExitOnForwardFailure) --- CLI/cmux.swift | 27 +++- Sources/TerminalController.swift | 6 +- Sources/Workspace.swift | 223

Socket API Contract Notes + +### 10.1 `workspace.remote.configure` Port Fields +1. `port` and `local_proxy_port` accept integer values and numeric strings. +2. Explicit `null` clears each field. +3. Out-of-range values and invalid types (for example booleans/non-numeric strings/fractional numbers) return `invalid_params`. +4. `local_proxy_port` is an internal deterministic test hook to force local bind conflicts in regression coverage. + +### 10.2 SSH Option Precedence +1. `StrictHostKeyChecking` default (`accept-new`) is only injected when no user override is present. +2. Control-socket defaults (`ControlMaster`, `ControlPersist`, `ControlPath`) are only injected when missing. +3. SSH option key matching is case-insensitive for precedence checks in both CLI-built commands and remote configure payloads. + +### 10.3 SSH Docker E2E Harness Knobs +1. `CMUX_SSH_TEST_DOCKER_HOST` sets the SSH destination host/IP used by docker-backed SSH fixtures (default `127.0.0.1`). +2. `CMUX_SSH_TEST_DOCKER_BIND_ADDR` sets the bind address used in fixture container publish mappings (default `127.0.0.1`). +3.

Uses TCP instead of Unix socket forwarding because many servers have `AllowStreamLocalForwarding` disabled. +- `DONE` background `ssh -N -R 127.0.0.1:PORT:127.0.0.1:LOCAL_RELAY_PORT` process reverse-forwards a TCP port to a dedicated authenticated local relay server. Uses TCP instead of Unix socket forwarding because many servers have `AllowStreamLocalForwarding` disabled. - `DONE` relay process uses `ControlPath=none` (avoids ControlMaster multiplexing and inherited `RemoteForward` directives) and `ExitOnForwardFailure=no` (inherited forwards from user ssh config failing should not kill the relay). - `DONE` relay address written to `~/.cmux/socket_addr` on the remote with a 3s delay after the relay process starts, giving SSH time to establish the `-R` forward. - `DONE` Go CLI re-reads `~/.cmux/socket_addr` on each TCP retry to pick up updated relay ports when multiple workspaces overwrite the file. - `DONE` `cmux ssh` startup exports session-local `CMUX_SOCKET_PATH=127.0.0.1:<relay_port>` so parallel sessions pin to their own relay instead of racing on shared socket_addr. - `DONE` relay startup writes `~/.cmux/relay/<relay_port>.daemon_path`; remote `cmux` wrapper uses this to select the right daemon binary per session, including mixed local cmux versions. +- `DONE` relay startup writes `~/.cmux/relay/<relay_port>.auth` with a relay ID and token; the local relay requires HMAC-SHA256 challenge-response before forwarding any command to the real local socket. - `DONE` ephemeral port range (49152-65535) filtered from probe results to exclude relay ports from other workspaces. - `DONE` multi-workspace port conflict detection uses TCP connect check (`isLoopbackPortReachable`) so ports already forwarded by another workspace are silently skipped instead of flagged as conflicts. - `DONE` orphaned relay SSH processes from previous app sessions are cleaned up before starting a new relay. +### 3.6 Artifact Trust +- `DONE` release and nightly workflows publish `cmuxd-remote` assets for `darwin/linux × arm64/amd64`. +- `DONE` release and nightly apps embed a compact `CMUXRemoteDaemonManifestJSON` in `Info.plist` with exact asset URLs and SHA-256 digests. +- `DONE` `cmux remote-daemon-status` exposes the current manifest entry, local cache verification state, release download command, and GitHub attestation verification command. + ### 3.3 Error Surfacing - `DONE` remote errors are surfaced in sidebar status + logs + notifications. - `DONE` reconnect retry count/time is included in surfaced error text (for example, `retry 1 in 4s`). diff --git a/scripts/build_remote_daemon_release_assets.sh b/scripts/build_remote_daemon_release_assets.sh new file mode 100755 index 00000000..a6be6fc6 --- /dev/null +++ b/scripts/build_remote_daemon_release_assets.sh @@ -0,0 +1,140 @@ +#!/usr/bin/env bash +set -euo pipefail + +usage() { + cat <<'EOF' +Usage: scripts/build_remote_daemon_release_assets.sh \ + --version <app-version> \ + --release-tag <tag> \ + --repo <owner/repo> \ + --output-dir <dir> + +Builds cmuxd-remote release assets for the supported remote platforms and emits: + cmuxd-remote-<goos>-<goarch> + cmuxd-remote-checksums.txt + cmuxd-remote-manifest.json +EOF +} + +VERSION="" +RELEASE_TAG="" +REPO="" +OUTPUT_DIR="" + +while [[ $# -gt 0 ]];
