- docker-compose.yml: run peer-a and peer-b with TS_USERSPACE=false +
/dev/net/tun device + cap_add. Pin peer-a's WG listen port to 41641
via TS_TAILSCALED_EXTRA_ARGS and publish it to the host so direct
UDP from outside docker has somewhere to land.
- run.sh: use an ephemeral pre-auth key for the test client so
Headscale auto-deletes the test node when its map stream drops
(instead of accumulating hundreds of stale entries that eventually
slow netmap propagation to a crawl). Disable shields-up on both
peers so the kernel firewall doesn't drop inbound tailnet TCP. Tweak
the JSON key extraction to handle pretty-printed output.
- integration.rs: add `test_e2e_tcp_through_tunnel` that brings up
the daemon, dials peer-a's echo server through the proxy, and
asserts the echo body comes back. Currently `#[ignore]`d — the
docker stack runs Headscale over plain HTTP, but Tailscale's client
unconditionally tries TLS to DERP relays ("tls: first record does
not look like a TLS handshake"), so peer-a can never receive
packets we forward via the relay. Unblocking needs either TLS
termination on the docker DERP or running the test inside the same
docker network as peer-a. Test stays in the tree because everything
it tests up to the read timeout is real verified behavior.
