WARNING: this is an unreviewed prototype; please do not assume this
works or is correct
The daemon's startBackendLocked reimplemented tsnet/tsnet.go's start()
nearly line-for-line — same tsd.NewSystem, netmon.New, tsdial.Dialer,
wgengine.NewUserspaceEngine, netstack.Create, netstack dial-hooks,
store.New, ipnlocal.NewLocalBackend, prefs, NeedsLogin handling, and
localapi.NewHandler. Plus the daemon kept its own GetTCPHandlerForFlow
listener registry, its own LocalAPI handler, and a hand-rolled
tailscaleIPs() reading from NetMapNoPeers.
This is a pure refactor: the daemon now constructs a tsnet.Server and
delegates to it. No tsnet code is touched.
startBackendLocked -> &tsnet.Server{...}.Start()
awaitRunning (Up) -> ts.Up(ctx)
RegisterListener -> ts.Listen + per-listener acceptLoop goroutine
serveDatapath dial -> ts.Dial
serveLocalAPI -> byte-splice via ts.LocalClient().Dial into
tsnet's in-process memnet localapi listener;
Hijacker and Flusher semantics still work
because we're a dumb byte pipe.
whoIs -> ts.LocalClient().WhoIs
tailscaleIPs -> ts.TailscaleIPs
CertDomains -> ts.CertDomains
Deletes the daemon-side getTCPHandlerForFlow / getUDPHandlerForFlow,
the listenerByKey registry, lookupListener, listenAddrFor +
pickEphemeralPort (tsnet's Listen handles port allocation), cmpOr,
the single-conn http.Server listener used to host our own localapi
handler, and the direct wgengine/magicsock/netstack/ipnlocal/
controlclient/tsdial/netmon/tsd/store/ipnauth/ipn/hostinfo imports.
Daemon size: 1160 -> 925 lines (-20%).
Mental surface in the daemon shrinks much more than the line count
because the heavy subsystems are no longer reached at all.
The integration test (TestTsnet2EndToEnd) still passes in ~8s; race
detector is clean. tsnet2/ (the client shim) is unchanged and still
imports zero of wgengine / magicsock / ipnlocal / netstack / localapi
/ controlclient (verified via go list -deps), so Goal 2 of the design
(WireGuard out of the app process) is preserved.
Minor behavior change: state file is now <state-dir>/tailscaled.state
instead of <state-dir>/tsnet2.state, because tsnet.Server picks the
filename. No v1 consumer depends on this.
Deferred: forwarding tsnet.Server.UserLogf (auth URLs etc.) over the
control channel to the app's UserLogf. tsnet logs them to its own
log.Printf for now.
