Whitelists are not working #9402

KevinKlinger · 2018-10-18T14:37:48Z

Describe the bug
I performed all actions as described in the docs.
The thing is I can get reviews with stars, which is definitely not intended.

It seems like all of my whitelists are not working since I tried others like the one described in #7766

Expected behavior
For the example in the docs I expected to see the productpage without stars, if I am not logged in as user jason.
For the example of #7766 I expected to get a 404 until I send requests with the correct x-api-key header.

Both configurations don't have any effect to the system.

Version
Istio: 1.0.2
K8s: 1.11.3

Installation
helm template install/kubernetes/helm/istio --name istio --namespace istio-system \
--set global.configValidation=false \
--set sidecarInjectorWebhook.enabled=false \
--set tracing.enabled=true \
--set tracing.jaeger.enabled=true \
--set kiali.enabled=false \
--set grafana.enabled=true

Environment
K8s, AWS

I encountered this problem on 1.0.0 too.

clyang82 · 2018-11-08T08:55:07Z

@KevinKlinger & @oulinbao I have tried 1.0.2 and 1.0.3. they are not working. But it works in istio-1.1.0-snapshot.2. so this issue should be fixed in release-1.1. I cannot test release-1.1, because there is a blocking issue - #9593. We can have a try after unblocking.

kyessenov · 2018-11-08T18:55:45Z

/assign @kyessenov
I'll take a look at this. @mandarjog given that 1.0.4 is imminent, we should back-port the fix.

kyessenov · 2018-11-08T22:57:36Z

I have tried the task but failed to reproduce the issue on 1.0.3. After creating the handler/instance/rule, I can see black starts only when I login as user "jason", and no stars, otherwise. A few things that can help us to debug further:

make sure to create handler/instance/rule in the same namespace as bookinfo application
it would help us to get complete policy logs:

Bump up logging level by editing kubectl edit deployment istio-policy -n istio-system, and adding --log_output_level=api:debug to mixer container, e.g.:

      - args:
        - --address
        - unix:///sock/mixer.socket
        - --configStoreURL=k8s://
        - --configDefaultNamespace=istio-system
        - --trace_zipkin_url=http://zipkin:9411/api/v1/spans
        - --log_output_level=api:debug

After observing the misbehavior, report the logs from policy mixer: kubectl logs -l istio-mixer-type=policy -n istio-system -c mixer

clyang82 · 2018-11-09T09:45:59Z

I guess that is relevant with the cache. I meet this issue in the first time, it works after. Then I delete kubectl delete -f /tmp/whitelist-handler.yaml ; kubectl delete -f /tmp/appversion-instance.yaml ; kubectl delete -f /tmp/checkversion-rule.yaml . the page is still shown Ratings service is currently unavailable. it works after 5 or more minutes.

clyang82 · 2018-11-09T09:48:42Z

Logout the productpage. re-apply the whitelist handler, it still show red stars. Here are logs:

kyessenov · 2018-11-09T19:12:14Z

Thanks for the logs. The log line that stands out to me is at the bottom "Publishing 3 events". It seems that Mixer received the config deletion events fairly late in the log. That means Mixer was operating with the old config state prior to receiving the events. This happens with a loaded API server that introduces a significant latency between kubectl commands and clients actually receiving the new state.

Note that check decisions are indeed cached:

Mixer has a central check cache. This doesn't happen here (you should see "Check approved from cache" if the cache is hit)
Each adapter also sets a caching interval for proxies. By default, it is 5 minutes for listchecker adapter:

istio/mixer/adapter/list/list.go

Line 269 in 405f47f

CachingInterval: 300 * time.Second,

You can change it with caching_duration field in params.

clyang82 · 2018-11-12T05:15:49Z

@kyessenov Thanks for your explanations.

kyessenov · 2018-11-12T21:13:39Z

Is there still an issue observed if we eliminate API server latency and caching duration?

clyang82 · 2018-11-13T01:24:55Z

There is no an issue from my view. I think we can close this issue if the Author (@KevinKlinger ) has no concerns.

KevinKlinger · 2018-11-13T12:54:14Z

I'm fine with your explanation.
Thank you for stating out the issue.
