[2224204] [crypto-policy] Connection validation fails for TLS v1.2 with the default tlsSecurityProfile

XMLWordPrintable

    • High
    • None

      Description of problem:
      ------------------------
      With the default tlsSecurityProfile (intermediate profile), connection validation for the components: virt-api, cdi-api, ssp-operator-service, ssp-operator-metrics, hostpath-provisioner-operator-service and kube-macpool-service, fails for TLS v1.2

      sh-5.1# openssl s_client -connect 172.30.29.99:443 -tls1_3 -brief <<< 'Q' 2>&1 | grep 'Protocol version'
      Protocol version: TLSv1.3
      sh-5.1# openssl s_client -connect 172.30.29.99:443 -tls1_2 -brief <<< 'Q' 2>&1 | grep 'Protocol version'
      sh-5.1# openssl s_client -connect 172.30.29.99:443 -tls1_1 -brief <<< 'Q' 2>&1 | grep 'Protocol version'
      sh-5.1#

      Version-Release number of selected component (if applicable):
      --------------------------------------------------------------
      CNV v4.13.3 & CNV 4.14

      How reproducible:
      -----------------
      Always

      Steps to Reproduce:
      -------------------
      0. Create a 6 node cluster ( 3 master + 3 worker ) with FIPS enabled.

      1. Get the IP & port number of a service 'virt-api'

      1. oc get service -n openshift-cnv | grep virt-api
        virt-api ClusterIP 172.30.29.99 <none> 443/TCP 17h2.

      2. Validate the connection from one of the worker node

      1. oc debug node/<worker-node>
      2. chroot /host
      3. openssl s_client -connect 172.30.29.99:443 -tls1_2 -brief <<< 'Q' 2>&1

      Actual results:
      ---------------
      Error when validating the connection with TLS v1.2
      sh-5.1# openssl s_client -connect 172.30.29.99:443 -tls1_2 -brief <<< 'Q' 2>&1
      Can't use SSL_get_servername
      depth=0 CN = virt-api.openshift-cnv.pod.cluster.local
      verify error:num=20:unable to get local issuer certificate
      depth=0 CN = virt-api.openshift-cnv.pod.cluster.local
      verify error:num=21:unable to verify the first certificate
      801BD9D4EC7F0000:error:1C8000E9:Provider routines:kdf_tls1_prf_derive:ems not enabled:providers/implementations/kdfs/tls1_prf.c:194:
      801BD9D4EC7F0000:error:0A08010C:SSL routines:tls1_PRF:unsupported:ssl/t1_enc.c:83:

      Expected results:
      -----------------
      Connection validation should be successful with TLS v1.2, like the same way it happens for TLS v1.3

      sh-5.1# openssl s_client -connect 172.30.29.99:443 -tls1_3 -brief <<< 'Q' 2>&1

      depth=0 CN = virt-api.openshift-cnv.pod.cluster.local
      verify error:num=21:unable to verify the first certificate

      Additional info:
      -----------------
      This issue is also found with CNV v4.14
