Normal UPDATE 42m nginx-ingress-controller ConfigMap ingress-nginx/ingress-nginx-controller

What happened:
We have webservices with self-signed certificates which we would like to access using ingress/nginx. When we enable TLSv1.2 on the webservices everything works, however when it is disabled the following error message occurs:

2022/02/18 10:33:26 [error] 2188#2188: *31100206 peer closed connection in SSL handshake while SSL handshaking to upstream, client: 10.244.3.1, server: intranetws.k8s-intra-rd.local, request: "GET /intranetws/ HTTP/2.0", upstream: "https://10.244.2.250:8081/intranetws/", host: "intranetws.k8s-intra-rd.local"

This happens even when ssl-protocols is set to TLSv1.3 only in the ingress controller config. It appears that ingress uses TLSv1.2 no matter the settings.

What you expected to happen:
We expected ingress/nginx to use TLSv1.3 if the application supports it and when configured to only use TLSv1.3.

How to reproduce it:
I'm assuming this can be reproduced using any application which supports only TLSv.1.3, but I have not yet tried it.

Anything else we need to know:

@bh-tt: This issue is currently awaiting triage.

If Ingress contributors determines this is a relevant issue, they will accept it by applying the triage/accepted label and provide further guidance.

The triage/accepted label can be added by org members by writing /triage accepted in a comment.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

longwuyuan · 2022-02-19T17:18:10Z

I am reading here https://www.cloudflare.com/learning/ssl/why-use-tls-1.3/ and if that means that using TLS 1.3 disables use of TLS 1.2 then backward compatibility breaks.

I am not a developer and a developer needs to comment.

rikatz · 2022-02-20T21:16:48Z

As far as I remember, TLS v1.3 has a lot of compatibility changes, that means that it cannot co-exist with TLS v1.2. I might be wrong and need to re-read about it.

Have you tried in your specific ingress setting:

nginx.ingress.kubernetes.io/proxy-ssl-protocols: TLSv1.3

?

It might be that the ciphers are incorrect:

#8507 (comment)

#7084 might also be related. Seems that even though I set proxy-ssl-ciphers it's probably not doing anything since it only works when proxy-ssl-secret is set.

chancez · 2022-08-24T20:02:08Z

For gRPC it might also be that grpc_ssl_ciphers isn't being set, but even when I try configuring it as a server-snippet/configuration-snippet, it doesn't change anything.

nginx.ingress.kubernetes.io/backend-protocol: HTTPS
nginx.ingress.kubernetes.io/configuration-snippet: |
  proxy_ssl_protocols TLSv1.3;

This work.

longwuyuan · 2024-04-30T09:28:09Z

the original issue-description is really badly formatted and its hard to get the small tiny required details there
there is a post that setting backend-protocol to HTTPS and using snippet to set TLSv1.3 worked
there is no traction on the issue since months
there are too many open issues that are inactive and do not provide a action-item for the project to track

So I am closing this issue for now. THe original creator of the issue can re-open the issue if data is posted here that shows a problem in the controller or implies a action0item on the project

thanks

That's fine, we have migrated to istio quite a while ago which supports it all just fine.

Tommyf · 2024-05-30T19:36:02Z

Could this be re-opened?

Yes, it works with the configuration-snippet, but that has recently become disabled by default (#10393). It's not advised to enable this setting due to CVE-2021-25742.

This all means that in order to adhere to good security practices (Use TLSv1.3), you need to ignore the CVE mitigation by enabling, and using, the configuration snippets.

It would be ideal if nginx.ingress.kubernetes.io/proxy-ssl-protocols: TLSv1.3 would work as expected.

This issue was mentioned briefly here but then someone mentions that there "are open issues" relating to this annotation. As best as I can figure out, this issue is the only one dealing with it, and it's been closed.

longwuyuan · 2024-05-30T19:43:13Z

@Tommyf can you paste every small detail using kubectl commands, curl commands, other commands, on a kind/minikube cluster with backend-protocol set to HTTPS and proxy-ssl-protocols annotation set to tlsv1.3
