Description nwaizer 2022-03-10 17:00:35 UTC 
Description of problem:
Hw-event-proxy is unreachable in a single stack ipv6 environment 

Version-Release number of selected component (if applicable):
hw-event-proxy 4.10

How reproducible:


Steps to Reproduce:
1. Deploy according to https://github.com/jzding/notes/tree/main/hw-event-proxy-operator
2. get app url using : oc get route
|-> hw-event-proxy-hw-event-proxy-operator-system.apps.kni-qe-2.lab.eng.rdu2.redhat.com

3. from a host in the ipv6 issue this request:
curl -k -X POST -d '' https://hw-event-proxy-hw-event-proxy-operator-system.apps.kni-qe-2.lab.eng.rdu2.redhat.com/webook




Actual results:
503 error

Expected results:
20x OK

Additional info:
When connecting to the app and issuing curl [::1]:9087 I get an error response.
curl 127.0.0.1:9087 gives ok

And from inside the cluster:
[kni ~]$ oc -n hw-event-proxy-operator-system exec -it hw-event-proxy-9bdb586d8-bxbqm -- curl http://127.0.0.1:9087 -I

Comment 1 nwaizer 2022-03-10 17:32:26 UTC 
yes, only ipv4 is avail now
Comment 2 Jack Ding 2022-03-11 14:04:40 UTC 
I confirm this is an issue with included fasthttp library in hw-event-proxy.
fasthttp server only listens to tcp4 sockets. 
https://github.com/valyala/fasthttp/blob/master/server.go#L1592

Will work on a fix ASAP.

Yet when submitting test event, no event appears in the app's log
Comment 5 nwaizer 2022-03-14 17:33:05 UTC 
when issuing this from a host in the ipv6 network 
$ curl -v -k -X POST -d '' https://hw-event-proxy-hw-event-proxy-operator-system.apps.kni-qe-2.lab.eng.rdu2.redhat.com/webhook

I get 503 error as before
Comment 6 nwaizer 2022-03-14 17:39:25 UTC 
when ssh to the app container I see it still does not answer local ipv6. It does answer ipv4:

Comment 7 Jack Ding 2022-03-14 18:35:48 UTC 
The image you used does not contain the fix since the fix was merged in mainstream, not in 4.10. I need it QE verified before cherry-picking it to 4.10.

     "image": "registry.kni-qe-0.lab.eng.rdu2.redhat.com:5000/openshift/origin-baremetal-hardware-event-proxy:4.10",

Please use image quay.io/openshift/origin-baremetal-hardware-event-proxy:latest
Comment 8 Jack Ding 2022-03-14 22:50:17 UTC 
You should be able to see this if the image is correct:

$ oc exec -it hw-event-proxy-5c4cf9b7c8-p25x9 -c hw-event-proxy -- curl -X POST [::1]:9087/webhook -I

Comment 9 nwaizer 2022-03-16 07:34:58 UTC 
New image installed on the disconnected IPv6 node, and indeed the command above works.
I also see the events, that I generate using SubmitTestEvent arriving at the app and sent to the message queue.
How ever the consumer installed according to https://github.com/jzding/notes/blob/main/hw-event-proxy-operator/consumer.yaml
Does not receive the events.
I notice the consumer is using IPV4 to connect to the broker, and asked Aneesh Puttur if I can use IPv6 for the AMQ.
He claims that IPv6 was never tested.
Will the user use IPV4 in the cluster for the message queue , and this is what I should test?
Or, should the AMQ be configured to use IPv6 and I should test that?
