…Route matching TranslateTCPRoute/TranslateUDPRoute emitted a single StreamRoute with no match criteria, so every TCP/UDP connection on any stream listener matched it. All L4 routes collided onto one backend, ignoring parentRefs.sectionName and per-listener port routing. The controllers now populate tctx.Listeners from the listeners ParseRouteParentRefs matched for each parentRef (honoring sectionName, port, protocol and allowedRoutes). The translator derives StreamRoute.server_port from the matched listener port(s), emitting one StreamRoute per port with a port-qualified name/ID so listeners no longer collide. Injection is gated locally (explicit sectionName/port targeting, or more than one distinct listener port); otherwise the previous single portless StreamRoute is kept for backward compatibility. L4 e2e listeners are updated to APISIX's real stream ports (TCP 9100, UDP 9200) so server_port isolation is exercised. Sync from apache/apisix-ingress-controller#2818 (fixes #2802)

What this PR does / why we need it:
Sync from apache/apisix-ingress-controller#2818 (fixes apache/apisix-ingress-controller#2802).
TranslateTCPRoute/TranslateUDPRouteemitted a singleStreamRoutewith no match criteria (the old// TODO: ... server_port). In APISIX stream mode a StreamRoute withoutserver_portmatches every connection on any stream listener, so all L4 routes across all Gateways collided onto one backend —parentRefs.sectionName/ per-listener port routing were ignored.Fix:
tcproute_controller.go,udproute_controller.go): populatetctx.Listenersfrom the listenersParseRouteParentRefsmatched for each parentRef (honoringsectionName, port, protocol,allowedRoutes).internal/controller/context.go+utils.go:RouteParentRefContextgains an additiveListenersslice;ParseRouteParentRefsrecords the matched listener(s); adds anappendListenershelper. The existing single-Listenerfield and match/break behavior are left intact (no HTTPRoute behavior change).tcproute.go,udproute.go): setStreamRoute.server_portfrom the matched listener port(s), one StreamRoute per port with a port-qualified name/ID.Gating (self-contained): EE has no
listener_port_match_mode, so injection is decided locally — injectserver_porton explicitsectionName/porttargeting, or when more than one listener port is matched; otherwise keep the previous single portless StreamRoute (backward compatible).Tests:
l4route_serverport_test.go): explicit sectionName injects the matching port; multi-listener fans out to distinct ServerPorts; dedup; single-listener-without-explicit stays portless; no-listener fallback. TCP + UDP.9100, UDP9200) soserver_portisolation is exercised.Scope: TLSRoute not included (has SNI as its L4 discriminator). Multi-listener fan-out from a single parentRef is not populated by
ParseRouteParentRefshere (EE keeps its match-and-break loop; the OSS hostname-helper refactor that removes the break was intentionally not ported to avoid changing HTTPRoute hostname behavior); fan-out across multiple parentRefs/gateways still works, and the sectionName isolation from the bug report is fully fixed.Pre-submission checklist:
