From 62bab77bd57237d6814703531f75808966003c11 Mon Sep 17 00:00:00 2001 From: Jawed khelil Date: Mon, 11 May 2026 14:05:47 +0200 Subject: [PATCH] feat(tls): make central TLS opt-out and enable ML-KEM for console plugin Change EnableCentralTLSConfig from an opt-in bool to an opt-out *bool so central TLS configuration is active by default on all OpenShift clusters (SRVKP-9615). SetDefaults now sets EnableCentralTLSConfig = true when the field is nil (e.g. existing CRs on upgrade). Users who need to manage TLS manually can set enableCentralTLSConfig: false to opt out. ResolveCentralTLSToEnvVars and GetPlatformData are updated to treat nil as enabled; only an explicit false suppresses TLS injection. Also add ssl_conf_command Groups X25519MLKEM768:X25519 to the nginx TLS directive builder for the console plugin. This enables the ML-KEM hybrid key exchange group required for PQC readiness whenever TLS 1.3 is in scope (which is always the case, since convertTLSVersionToNginx always includes TLSv1.3). Fixes the PQC TLS scan failure: PQC: ML-KEM not supported (no x25519mlkem768 or mlkem768) Signed-off-by: Jawed khelil Assisted-by: Claude Sonnet 4.6 (via Cursor) Co-authored-by: Cursor --- .../operator/v1alpha1/openshift_platform.go | 17 +++++++------- .../v1alpha1/tektonconfig_defaults.go | 6 +++++ .../v1alpha1/zz_generated.deepcopy.go | 5 ++++ pkg/reconciler/openshift/common/tlsprofile.go | 5 +++- .../openshift/common/tlsprofile_test.go | 23 +++++++++++++++++-- .../openshift/tektonconfig/extension.go | 3 ++- 6 files changed, 46 insertions(+), 13 deletions(-) diff --git a/pkg/apis/operator/v1alpha1/openshift_platform.go b/pkg/apis/operator/v1alpha1/openshift_platform.go index 19493b5a74..daa9b8b0a2 100644 --- a/pkg/apis/operator/v1alpha1/openshift_platform.go +++ b/pkg/apis/operator/v1alpha1/openshift_platform.go @@ -23,16 +23,15 @@ type OpenShift struct { // SCC allows configuring security context constraints used by workloads // +optional SCC *SCC `json:"scc,omitempty"` - // EnableCentralTLSConfig enables TLS configuration inheritance from - // the cluster's APIServer TLS security profile.
