When we do a GetProfile lookup for an opaque port on an unmeshed pod, we attempt to look up the inbound listen port of that pod's proxy. Since that pod has no proxy, this fails and we return an error to the GetProfile API call. This causes the proxy to fail to be able to resolve the profile and be unable to route the traffic. We revert to the previous behavior of only logging when we cannot look up the inbound listen port instead of returning an error. Signed-off-by: Alex Leong <[email protected]>
## stable-2.14.3 This stable release fixes an issue in the Destination controller that was forbidding to route traffic to opaque ports on unmeshed pods. Also, it increases the log level from debug to warning when the outbound proxy faces this type of events. * Fixed `GetProfiles` error when address is opaque and unmeshed ([#11556], fixes[#11555]) * Started logging at warning level when the controller clients receive an error ([#2499]) [#11556]: #11556 [#11555]: #11555 [#2499]: linkerd/linkerd2-proxy#2499

There was a problem hiding this comment.
Looks good. Had a nit but it's not blocking by any means. Thanks!
