New zt-gateway-setup script with subcommands for configuring this
router as a ZeroTier exit gateway: bridge, routing (tables 100/101),
DHCP, hotplug, and persistence. Exposes setup ubus method via backend
with ACL and LuCI panel in overview.
Also fixes two pre-existing test issues:
- overview.spec.ts: active gateway radio is intentionally enabled
(users need to re-trigger switch for the already-selected gateway)
- drain.spec.ts: stubs drain status via page.route() since Docker
has no real conntrack entries; fixed Playwright glob pattern bug
where **/ubus* fails to match /ubus/?timestamp (regex needed)
Adds the luci-app-zt-gateway package: a LuCI app + rpcd/ucode backend +
shell switch script that reconfigures which remote ZeroTier node acts as
the internet exit gateway for WIBLAN clients (10.11.13.0/24).
- Makefile (luci.mk, arch-independent)
- UCI config skeleton with three sample gateways
- rpcd ACL + menu entry
- zt-gateway.uc rpcd backend exposing status / switch / health /
drain_status / cancel_drain ubus methods
- zt-gateway-switch shell script implementing force + graceful modes:
* force: pre-flight ping, atomic route replace, conntrack flush,
UCI/hotplug/rc.local persistence
* graceful: dual-table drain using CONNMARK fwmark 0x100 at
priority 99, background drain monitor with two-consecutive-zero
completion and timeout-forced fallback to force
- LuCI overview.js: gateway radio list, mode select, drain progress
panel, cancel-drain button, health polling
- Docker test harness (docker-compose + Dockerfile.router +
router/gw entrypoints) exercising the switch script against real
iproute2/iptables/conntrack on two simulated exit nodes
Verified against the harness: force switch, graceful drain to natural
completion, pre-flight blocking of unreachable gateways (force + graceful),
and drain-timeout forced fallback.
