Description Miciah Dashiel Butler Masters 2019-10-03 23:52:25 UTC

+++ This bug was initially created as a clone of Bug #1723400 +++

Description of problem:

Even though the EXTENDED_VALIDATION is set to true, adding a certificate to a specific `route` with the wrong key will cause the `router` to fail during re-load which can impact production services as changes within the service are not properly reflected.

With EXTENDED_VALIDATION on, it's expected to decline such route from being created and prevent the `router` from failing.

Version-Release number of selected component (if applicable):

> oc v3.9.74
> kubernetes v1.9.1+a0ce1bc657
> features: Basic-Auth GSSAPI Kerberos SPNEGO
> 
> Server https://openshift.example.com:443
> openshift v3.9.74
> kubernetes v1.9.1+a0ce1bc657

How reproducible:
Always


Steps to Reproduce:
1. Make sure EXTENDED_VALIDATION is set to `true` on the `router`
2. Create a route with Edge termination set and apply a custom certificate.
3. Add a wrong key for the certificate (not matching) and create the route

Actual results:

`router` is failing to reload and thus apply changes within it's configuration. Error reported by `router` is as following.

E0620 09:53:43.202882       1 limiter.go:137] error reloading router: exit status 1

[ALERT] 170/095408 (13581) : Fatal errors found in configuration.

Expected results:

`router` to reject the `route` in order to continue to function properly and simply notify the creator of the `route` that it was not possible to create the `route` due to validation error.
