      Previously, the AWS EFS driver controller returned a runtime error when it provisioned a new volume on EFS filesystem if pre-existing access points without a POSIX user were present. With this release, the driver has been fixed and the issue has been resolved. (link:https://issues.redhat.com/browse/OCPBUGS-34843[*OCPBUGS-34843*])

      Description of problem:

      After upgrading the OCP cluster from 4.14.22 to 4.15.11 customer started to see the aws-efs-csi-driver-controller pods in crash look back off status in the openshift-cluster-csi-drivers namespace

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

      OCP 4.15.11
AWS EFS CSI Driver v1.7.0

      How reproducible:

      It happens all the time in customer environment  

      Steps to Reproduce:

      1. Upgrade OCP from 4.14 to 4.15, AWS driver version that comes with 4.15 is v1.7.0, while with 4.14 was v1.5.3
2. Try to provision a new volume with AWS EFS CSI driver

      Actual results:

      Provisioning fails with an "invalid memory address or nil pointer dereference"

      Expected results:

      Provisioning should work without issues

      Additional info:

      Issue described seems similar to what was reported in https://github.com/kubernetes-sigs/aws-efs-csi-driver/issues/1164 and https://github.com/kubernetes-sigs/aws-efs-csi-driver/issues/1173
PR with the fix was https://github.com/kubernetes-sigs/aws-efs-csi-driver/pull/1167 but it wasn't merged
According to https://github.com/kubernetes-sigs/aws-efs-csi-driver/issues/1164#issuecomment-1806237765, this was already fixed in v.1.7.1 but this version of the driver isn't available in OCP 4.15.
