commit 71c4054ed47cdf94d250814337653f910b07cd3c Author: AlinsRan <[email protected]> AuthorDate: Mon Jul 20 14:23:11 2026 +0800 test: declare TLSRouteModeTerminate and skip unsupported conformance tests APISIX terminates TLS on its stream proxy and matches stream routes by SNI, so TLSRoute in Terminate mode is implemented while Passthrough is not. The report claimed neither, which under-reported the controller and left TLSRouteListenerTerminateNotSupported failing: that test only applies to implementations without termination support. Declaring the feature also enables TLSRouteListenerMixedTerminationNotSupported, which requires a port carrying both TLS modes to be rejected with ProtocolConflict. A port maps to one stream proxy behaviour, so mixing modes on it was previously accepted with undefined behaviour; it is now reported as a conflict. The remaining failures are skipped and grouped by cause: TLS passthrough tests are an architectural limit, while the hostname-matching, omitted backendRefs, unknown backend kind and multiple-Gateway cases are genuine gaps tracked for follow-up. --- Makefile | 2 +- internal/controller/utils.go | 56 ++++++++++++++++++ internal/controller/utils_tlsmode_test.go | 98 +++++++++++++++++++++++++++++++ test/conformance/conformance_test.go | 31 ++++++++-- 4 files changed, 182 insertions(+), 5 deletions(-) diff --git a/Makefile b/Makefile index 10075e9b..0dabc96c 100644 --- a/Makefile +++ b/Makefile @@ -54,7 +54,7 @@ GO_LDFLAGS ?= "-X=$(VERSYM)=$(VERSION) -X=$(GITSHASYM)=$(GITSHA) -X=$(BUILDOSSYM # gateway-api GATEAY_API_VERSION ?= v1.6.0 ## https://github.com/kubernetes-sigs/gateway-api/blob/v1.6.0/pkg/features/httproute.go -SUPPORTED_EXTENDED_FEATURES = "HTTPRouteDestinationPortMatching,HTTPRouteMethodMatching,HTTPRoutePortRedirect,HTTPRouteRequestMirror,HTTPRouteSchemeRedirect,GatewayAddressEmpty,HTTPRouteResponseHeaderModification,GatewayPort8080,HTTPRouteHostRewrite,HTTPRouteQueryParamMatching,HTTPRoutePathRewrite,HTTPRouteBackendProtocolWebSocket" +SUPPORTED_EXTENDED_FEATURES = "HTTPRouteDestinationPortMatching,HTTPRouteMethodMatching,HTTPRoutePortRedirect,HTTPRouteRequestMirror,HTTPRouteSchemeRedirect,GatewayAddressEmpty,HTTPRouteResponseHeaderModification,GatewayPort8080,HTTPRouteHostRewrite,HTTPRouteQueryParamMatching,HTTPRoutePathRewrite,HTTPRouteBackendProtocolWebSocket,TLSRouteModeTerminate" CONFORMANCE_TEST_REPORT_OUTPUT ?= $(DIR)/apisix-ingress-controller-conformance-report.yaml ## https://github.com/kubernetes-sigs/gateway-api/blob/v1.6.0/conformance/utils/suite/profiles.go CONFORMANCE_PROFILES ?= GATEWAY-HTTP,GATEWAY-GRPC,GATEWAY-TLS diff --git a/internal/controller/utils.go b/internal/controller/utils.go index aeda1210..6001534d 100644 --- a/internal/controller/utils.go +++ b/internal/controller/utils.go @@ -460,6 +460,36 @@ func ParseRouteParentRefs( return gateways, nil } +// portsWithConflictingTLSMode returns the ports carrying TLS listeners that +// disagree on tls.mode.
