Envoy can assert fail if local close reason is not set: envoy bug failure: !local_close_reason.empty(). Details: Local Close Reason was not set! Set error detail on local close to prevent this. Also Flush on proxylib close so that any remaining data is not cut off. Signed-off-by: Jarno Rajahalme <[email protected]>
Add enforce_policy_on_l7_lb to bpf_metadata config to maintain backwards compatibility by explicitly turning on policy enforcement on Ingress to support older Cilium releases on the same Envoy build. Store the original source identity for enforcing ingress policy for Ingress, that otherwise only enforces the egress policy, as it operates on the egress path. Now both ingress and egress policies for the ingress identity are enforced when enforce_policy_on_l7_lb is configured as 'true'. Ingress arrives to Cilium nodes at node ports, which are meaningless for Cilium Network Policies. To remedy this the destination port of the selected backend is used also in ingress path policy enforcement. Note that this destination port may be different from the one the traffic was first received at the external load balancer.

Refactor Config::getMetadata() processing of L7 LB config to be more explicit and to error out on invalid config so that invalid traffic does not accidentally slip through. Adjust tests accordingly and add new tests to cover the new 'enforce_policy_on_l7lb' option. Signed-off-by: Jarno Rajahalme <[email protected]>
