    Summary: Istio may not check inbound TCP connections against istio-policy

    Details: Istio 1.1.x through 1.1.6 has Incorrect Access Control. When `disablePolicyChecks` is set to `false`, inbound TCP connections do not generate Check requests to istio-policy and external authorization is not applied. This behavior is a result of a change to `istio/pilot/pkg/networking/plugin/mixer/mixer.go` in 1.1.
