Description Sergiusz Urbaniak 2022-01-05 11:03:01 UTC
+++ This bug was initially created as a clone of Bug #2037272 +++

Starting with Go 1.17 support for invalid certificates is going to be removed, see https://go.dev/doc/go1.17. This means that legacy certificates not having a SAN field but relying on the CN field will not be accepted by Go 1.17 based TLS clients any more.

The temporary `GODEBUG=x509ignoreCN=0` environment variable has been removed as of Go 1.17.

--- Additional comment from Sergiusz Urbaniak on 2022-01-05 11:01:43 UTC ---

Closing as with CURRENTRELEASE resolution as we can only implement preventive fixes in 4.9 only.

Comment 8 Yash Tripathi 2022-02-07 12:47:12 UTC
As discussed, this bz needs further comprehensive verification

Comment 9 Xingxing Xia 2022-02-08 16:01:21 UTC
Hoo, this bug is more like a complex epic! It contains so many OpenShift PRs and OEP https://github.com/openshift/enhancements/pull/980 ! I read through them and digested them now. To verify it, needs customize various certs like KAS cert, Apiserver webhook cert, aggregated apiserver cert, component routes like oauth route cert, various Auth external IDP servers' certs like OpenID server certs and test them all. Big test work!
Apiserver webhook cert and aggregated cert detection is from upstream k8s, and may need Apiserver QE teammates to provide help to test apiserver_webhooks_x509_missing_san_total and apiserver_kube_aggregator_x509_missing_san_total, Sergiusz, do you think we need to test them again?
For today, after investigating the PRs and code, time is only enough for me to test one of them, the test steps are lengthy, see next comment.

Comment 10 Xingxing Xia 2022-02-08 16:02:47 UTC
Continuing previous comment for Auth IDP no-SAN cert:
Prepare cert without SAN:
mkdir test_cert_no_san
cd test_cert_no_san
openssl genrsa -out serverKey.pem 2048

Make the cert used in Auth OpenID server:
oc new-project keycloak
oc process -f https://raw.githubusercontent.com/keycloak/keycloak-quickstarts/latest/openshift-examples/keycloak.yaml \
    -p KEYCLOAK_USER=admin \
    -p KEYCLOAK_PASSWORD=SNIPPED \

oc set volume dc/keycloak --add --name volume1 -t secret -m /etc/x509/https --secret-name keycloak-x509-https

Login keycloak admin UI, create a client like OCP-41149 keycloak case.
echo -n 'KEYCLOAK_CLIENT_SECRET' > keycloak-oidc-secret.txt
oc create secret generic keycloak-oidc-secret --from-file=clientSecret=keycloak-oidc-secret.txt -n openshift-config
oc create configmap keycloak-oidc-ca --from-file=ca.crt=caCert.pem -n openshift-config

Login to Prometheus UI, check openshift_auth_x509_missing_san_total, there is a non-zero count for OpenID:
...
openshift_auth_x509_missing_san_total{container="oauth-openshift", endpoint="https", instance="10.129.0.48:6443", job="oauth-openshift", namespace="openshift-authentication", pod="oauth-openshift-68dd878759-kng5z", provider="LDAP", service="oauth-openshift"}

...

That is, invalid Auth IDP cert is detected and Upgradeable is False to prevent user to upgrade to 4.10, this verifies the auth PRs.

Comment 12 Xingxing Xia 2022-02-09 10:44:15 UTC
Tested oauth-openshift route cert customization, filed separate bug 2052467 to track it after confirming with Dev.
For apiserver_webhooks_x509_missing_san_total and apiserver_kube_aggregator_x509_missing_san_total test, asked Apiserver QE guys to help test, testing is on going.

Comment 14 jmekkatt 2022-02-11 10:30:41 UTC
Recover tests confirmed that the kube-apiserver fails to recover when server certificates without SAN detected in webhooks replaced by certificates with SAN.

kube-apiserver has set to "upgradable:false" as the server certificates without SAN detected in webhooks.
To recover from this sitaition, replaced the certificate with SAN and waited the status to clear from the kube-apiserver.
kube-apiserver fails to clear the status "upgradable:false" even after longer wait.
It has also noted that the mertic "apiserver_webhooks_x509_missing_san_total" value hasn't reset to zero during above situation.

Please find the steps to reproduce the issue below.

1. Pre-condition : Create kube-apiserver status "upgradable:false" by referring certificates without SAN.
Follow the steps in https://bugzilla.redhat.com/show_bug.cgi?id=2037274#c13

2.Create certificates with SAN

openssl genrsa -out caKey.pem 2048
openssl req -x509 -new -nodes -key caKey.pem -days 100000 -out caCert.pem -subj "/CN=wb_ca"
openssl genrsa -out serverKey.pem 2048
cat > server.conf << EOF
[req]
req_extensions = v3_req
distinguished_name = req_distinguished_name
[req_distinguished_name]
[ v3_req ]
basicConstraints = CA:FALSE
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
extendedKeyUsage = clientAuth, serverAuth
subjectAltName = @alt_names
[alt_names]
IP.1 = 127.0.0.1
DNS.1 = opa.opa.svc
EOF
openssl req -new -key serverKey.pem -out serverWithSAN.csr -subj "/CN=opa.opa.svc" -config server.conf
openssl x509 -req -in serverWithSAN.csr -CA caCert.pem -CAkey caKey.pem -CAcreateserial -out serverCertWithSAN.pem -days 100000 -extensions v3_req -extfile server.conf

3. Delete existing tls secret
oc delete secrets opa-server -n opa

4. Create new secret with SAN cert
oc create secret tls opa-server --cert=serverCertWithSAN.pem --key=serverKey.pem -n opa

5. Delete webhook and recreate with certificates with SAN
$ oc delete ValidatingWebhookConfiguration opa-validating-webhook
$ cat > webhook-configuration.yaml <<EOF
 kind: ValidatingWebhookConfiguration
 apiVersion: admissionregistration.k8s.io/v1
 metadata:

         scope: 'Namespaced'
     clientConfig:
       caBundle: $(cat serverCertWithSAN.pem | base64 | tr -d '\n')
       service:
         namespace: opa
         name: opa
EOF
$ oc apply -f webhook-configuration.yaml

6. Restart the opa pods to get the new secret changes.
$ oc delete replicaset <replica_name> -n opa

7. Describe the kube-apiserver to see the status.
$ oc describe co/kube-apiserver

Name:         kube-apiserver
    ........
    Last Transition Time:  2022-02-11T06:58:15Z

    Reason:                InvalidCerts_InvalidCertsDetected
    Status:                False
    Type:                  Upgradeable
  Extension:               <nil>

Check  prometheus UI, for apiserver_webhooks_x509_missing_san_total matric value.

apiserver_webhooks_x509_missing_san_total{apiserver="kube-apiserver", endpoint="https", instance="10.0.0.6:6443", job="apiserver", namespace="default", service="kubernetes"}
9
apiserver_webhooks_x509_missing_san_total{apiserver="kube-apiserver", endpoint="https", instance="10.0.0.7:6443", job="apiserver", namespace="default", service="kubernetes"}
4
apiserver_webhooks_x509_missing_san_total{apiserver="kube-apiserver", endpoint="https", instance="10.0.0.8:6443", job="apiserver", namespace="default", service="kubernetes"}
33

As you see above, the kube-apiserver failed to recover from the current status (i.e. upgradable:false due to certificates without SAN in webhook even after replaced by certificates with SAN).
Also note that in prometheus UI, the apiserver_webhooks_x509_missing_san_total count wasn't reset to zero.

For apiserver_kube_aggregator_x509_missing_san_total test, retested comment 15 with latest 4.9 payload, got the same results as expected.

Will verify the cert with SAN for aggregator apiserver,

- Check prometheus UI, for apiserver_kube_aggregator_x509_missing_san_total matric value, and wait more than 5m, check it again, the count still keeps the same results without any changes.

apiserver_kube_aggregator_x509_missing_san_total	kube-apiserver		https	10.0.155.45:6443	apiserver	default		openshift-monitoring/k8s	kubernetes	72
apiserver_kube_aggregator_x509_missing_san_total	kube-apiserver		https	10.0.171.167:6443	apiserver	default		openshift-monitoring/k8s	kubernetes	111

Based on above, the kube-apiserver verified the aggregator apiserver using cert w or w/o SAN as expected.

Verified openshift_auth_x509_missing_san_total in 4.9.0-0.nightly-2022-03-15-215745 . To avoid the bug is further too crowded and lengthy, the verification steps are put in doc https://docs.google.com/document/d/1E0s2jp_zpeJGPOZ-iSBe1sYFvK1C659Ut-X0y7JpQ6c/edit#heading=h.aipr2g1orltn "Verification for openshift_auth_x509_missing_san_total" section. Conclusion: when SAN-less cert is used in IDP server, ' sum by (provider) (increase(openshift_auth_x509_missing_san_total{job="oauth-openshift",namespace="openshift-authentication"}[30m])) or on() vector(0) ' is positive and will trigger Upgradeable as False; when the IDP server is updated with SAN cert, and wait for 30mins, the query is down to zero and Upgradeable turns to True again.
Note: the fix has a flaw, that is, even if we do nothing but just wait for 30 mins, the operator's Upgradeable can still turn to True. This should be a flaw that can't be fixed in theory.
