The CSI specification for `ValidateVolumeCapability` says that we shall "reconcile successful capability-validation responses by comparing the validated capabilities with those that it had originally requested" but leaves the details of that reconcilation unspecified. This API is not implemented in Kubernetes, so controller plugins don't have a real-world implementation to verify their behavior against. We have found that CSI plugins in the wild may return "successful" but incomplete `VolumeCapability` responses, so we can't require that all capabilities we expect have been validated, only that the ones that have been validated match. This appears to violate the CSI specification but until that's been resolved in upstream we have to loosen our validation requirements. The tradeoff is that we're more likely to have runtime errors during `NodeStageVolume` instead of at the time of volume registration. |
