## Changelog since v1.18.17

## Important Security Information

This release contains changes that address the following vulnerabilities:

### CVE-2021-25735: Validating Admission Webhook does not observe some previous fields

A security issue was discovered in kube-apiserver that could allow node
updates to bypass a Validating Admission Webhook. You are only affected
by this vulnerability if you run a Validating Admission Webhook for Nodes
that denies admission based at least partially on the old state of the
Node object.

**Note**: This only impacts validating admission plugins that rely on old
values in certain fields, and does not impact calls from kubelets that go
through the built-in NodeRestriction admission plugin.

**Affected Versions**:
  - kube-apiserver v1.20.0 - v1.20.5
  - kube-apiserver v1.19.0 - v1.19.9
  - kube-apiserver <= v1.18.17

**Fixed Versions**:
  - kube-apiserver v1.21.0
  - kube-apiserver v1.20.6
  - kube-apiserver v1.19.10
  - kube-apiserver v1.18.18

This vulnerability was reported by Rogerio Bastos & Ari Lima from RedHat


**CVSS Rating:** Medium (6.5) [CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H)

## Changes by Kind

### API Change

- Fixes using server-side apply with APIService resources ([#100715](https://github.com/kubernetes/kubernetes/pull/100715), [@kevindelgado](https://github.com/kevindelgado)) [SIG API Machinery, Apps, CLI and Testing]
- Regenerate protobuf code to fix CVE-2021-3121 ([#100514](https://github.com/kubernetes/kubernetes/pull/100514), [@joelsmith](https://github.com/joelsmith)) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Node]

### Feature

- AWS cloudprovider will ignore provisioning load balancers if the annotation service.beta.kubernetes.io/aws-load-balancer-type is external or nlb-ip ([#97973](https://github.com/kubernetes/kubernetes/pull/97973), [@kishorj](https://github.com/kishorj)) [SIG Cloud Provider]

### Bug or Regression

- Fixed a bug where a high churn of events was causing master instability by reducing the maximum number of objects (events) attached to a single etcd lease. ([#100452](https://github.com/kubernetes/kubernetes/pull/100452), [@mborsz](https://github.com/mborsz)) [SIG API Machinery and Instrumentation]
- Fixed a race condition on API server startup ensuring previously created webhook configurations are effective before the first write request is admitted. ([#95783](https://github.com/kubernetes/kubernetes/pull/95783), [@roycaihw](https://github.com/roycaihw)) [SIG API Machinery]
- Fixes a data race issue in the priority and fairness API server filter ([#100670](https://github.com/kubernetes/kubernetes/pull/100670), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]
- HTTP/2 connection health check is enabled by default in all Kubernetes clients to fix persistently broken connections (https://github.com/kubernetes/client-go/issues/374). If needed, users can tune the feature via the HTTP2_READ_IDLE_TIMEOUT_SECONDS and HTTP2_PING_TIMEOUT_SECONDS environment variables. The feature is disabled if HTTP2_READ_IDLE_TIMEOUT_SECONDS is set to 0. ([#100376](https://github.com/kubernetes/kubernetes/pull/100376), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Node]
- Reverts breaking change to inline AzureFile volumes in v1.18.15-v1.18.17; referenced secrets are now correctly searched for in the same namespace as the pod as in previous releases. ([#100397](https://github.com/kubernetes/kubernetes/pull/100397), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- The maximum number of ports allowed in EndpointSlices has been increased from 100 to 20,000 ([#99795](https://github.com/kubernetes/kubernetes/pull/99795), [@robscott](https://github.com/robscott)) [SIG Network]

## Changelog since v1.18.5

## Urgent Upgrade Notes

### (No, really, you MUST read this before you upgrade)

 - CVE-2020-8559 (Medium): Privilege escalation from compromised node to cluster. See https://github.com/kubernetes/kubernetes/issues/92914 for more details.
  The API Server will no longer proxy non-101 responses for upgrade requests. This could break proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code. ([#92941](https://github.com/kubernetes/kubernetes/pull/92941), [@tallclair](https://github.com/tallclair)) [SIG API Machinery]
 
## Changes by Kind

### API Change

- Fix bug in reflector that couldn't recover from "Too large resource version" errors ([#92537](https://github.com/kubernetes/kubernetes/pull/92537), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]

### Bug or Regression

- CVE-2020-8557 (Medium): Node-local denial of service via container /etc/hosts file. See https://github.com/kubernetes/kubernetes/issues/93032 for more details. ([#92916](https://github.com/kubernetes/kubernetes/pull/92916), [@joelsmith](https://github.com/joelsmith)) [SIG Node]
- Containers which specify a `startupProbe` but not a `readinessProbe` were previously considered "ready" before the `startupProbe` completed, but are now considered "not-ready". ([#92196](https://github.com/kubernetes/kubernetes/pull/92196), [@thockin](https://github.com/thockin)) [SIG Node]
- Extend kube-apiserver /readyz with new "informer-sync" check ensuring that internal informers are synced. ([#92644](https://github.com/kubernetes/kubernetes/pull/92644), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Testing]
- Fix throttling issues when Azure VM computer name prefix is different from VMSS name ([#92793](https://github.com/kubernetes/kubernetes/pull/92793), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]
- Fix: GetLabelsForVolume panic issue for azure disk PV ([#92166](https://github.com/kubernetes/kubernetes/pull/92166), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]
- Fix: don't use docker config cache if it's empty ([#92330](https://github.com/kubernetes/kubernetes/pull/92330), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]
- Fix: use force detach for azure disk ([#91948](https://github.com/kubernetes/kubernetes/pull/91948), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]
- Fixes a problem with 63-second or 1-second connection delays with some VXLAN-based
  network plugins which was first widely noticed in 1.16 (though some users saw it
  earlier than that, possibly only with specific network plugins). If you were previously
  using ethtool to disable checksum offload on your primary network interface, you should
  now be able to stop doing that. ([#92035](https://github.com/kubernetes/kubernetes/pull/92035), [@danwinship](https://github.com/danwinship)) [SIG Network and Node]
- Kubeadm: add the deprecated flag --port=0 to kube-controller-manager and kube-scheduler manifests to disable insecure serving. Without this flag the components by default serve (e.g. /metrics) insecurely on the default node interface (controlled by --address). Users that wish to override this behavior and enable insecure serving can pass a custom --port=X via kubeadm's "extraArgs" mechanic for these components. ([#92720](https://github.com/kubernetes/kubernetes/pull/92720), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: during "join", don't re-add an etcd member if it already exists in the cluster. ([#92118](https://github.com/kubernetes/kubernetes/pull/92118), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- hyperkube: Use debian-hyperkube-base@v1.1.1 image
  
    Includes iproute2 to fix a regression in hyperkube images
    when using hyperkube as a kubelet ([#92624](https://github.com/kubernetes/kubernetes/pull/92624), [@justaugustus](https://github.com/justaugustus)) [SIG Cluster Lifecycle, Network and Release]

## Changelog since v1.18.4

## Changes by Kind

### API Change

- Fixed: log timestamps now include trailing zeros to maintain a fixed width ([#91207](https://github.com/kubernetes/kubernetes/pull/91207), [@iamchuckss](https://github.com/iamchuckss)) [SIG Apps and Node]

### Bug or Regression

- Fixes CSI volume attachment scaling issue by using informers. ([#91307](https://github.com/kubernetes/kubernetes/pull/91307), [@yuga711](https://github.com/yuga711)) [SIG API Machinery, Apps, Node, Storage and Testing]
- Kubeadm increased to 5 minutes its timeout for the TLS bootstrapping process to complete upon join ([#89735](https://github.com/kubernetes/kubernetes/pull/89735), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]
- hyperkube: Use debian-hyperkube-base@v1.1.0 image
  
    A previous release built hyperkube using the debian-hyperkube-base@v1.0.0,
    which was updated to address a CVE in the CNI plugins.
    
    A side-effect of using this new image was that the networking packages
    (namely `iptables`) drifted from the versions used in the kube-proxy images.
  
    The following issues were filed on kube-proxy failures when using hyperkube:
    - https://github.com/kubernetes/kubernetes/issues/92275
    - https://github.com/kubernetes/kubernetes/issues/92272
    - https://github.com/kubernetes/kubernetes/issues/92250
  
    To address this, the new debian-hyperkube-base image (v1.1.0) uses the
    debian-iptables base image (v12.1.0), which includes iptables-wrapper, a
    script used to determine the correct iptables mode to run in. ([#92493](https://github.com/kubernetes/kubernetes/pull/92493), [@justaugustus](https://github.com/justaugustus)) [SIG Cluster Lifecycle and Release]

feedback!

## What’s New (Major Themes)

### Kubernetes Topology Manager Moves to Beta - Align Up!

A beta feature of Kubernetes in release 1.18, the [Topology Manager feature](https://github.com/nolancon/website/blob/f4200307260ea3234540ef13ed80de325e1a7267/content/en/docs/tasks/administer-cluster/topology-manager.md) enables NUMA alignment of CPU and devices (such as SR-IOV VFs) that will allow your workload to run in an environment optimized for low-latency. Prior to the introduction of the Topology Manager, the CPU and Device Manager would make resource allocation decisions independent of each other. This could result in undesirable allocations on multi-socket systems, causing degraded performance on latency critical applications.

### Serverside Apply - Beta 2

Server-side Apply was promoted to Beta in 1.16, but is now introducing a second Beta in 1.18. This new version will track and manage changes to fields of all new Kubernetes objects, allowing you to know what changed your resources and when.

### Extending Ingress with and replacing a deprecated annotation with IngressClass

In Kubernetes 1.18, there are two significant additions to Ingress: A new `pathType` field and a new `IngressClass` resource. The `pathType` field allows specifying how paths should be matched. In addition to the default `ImplementationSpecific` type, there are new `Exact` and `Prefix` path types. 

The `IngressClass` resource is used to describe a type of Ingress within a Kubernetes cluster. Ingresses can specify the class they are associated with by using a new `ingressClassName` field on Ingresses. This new resource and field replace the deprecated `kubernetes.io/ingress.class` annotation.

### SIG CLI introduces kubectl debug

SIG CLI was debating the need for a debug utility for quite some time already. With the development of [ephemeral containers](https://kubernetes.io/docs/concepts/workloads/pods/ephemeral-containers/), it became more obvious how we can support developers with tooling built on top of `kubectl exec`. The addition of the `kubectl debug` [command](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cli/1441-kubectl-debug/README.md) (it is alpha but your feedback is more than welcome), allows developers to easily debug their Pods inside the cluster. We think this addition is invaluable.  This command allows one to create a temporary container which runs next to the Pod one is trying to examine, but also attaches to the console for interactive troubleshooting.

### Introducing Windows CSI support alpha for Kubernetes

With the release of Kubernetes 1.18, an alpha version of CSI Proxy for Windows is getting released. CSI proxy enables non-privileged (pre-approved) containers to perform privileged storage operations on Windows. CSI drivers can now be supported in Windows by leveraging CSI proxy.
SIG Storage made a lot of progress in the 1.18 release.
In particular, the following storage features are moving to GA in Kubernetes 1.18:
- Raw Block Support: Allow volumes to be surfaced as block devices inside containers instead of just mounted filesystems.
- Volume Cloning: Duplicate a PersistentVolumeClaim and underlying storage volume using the Kubernetes API via CSI.
- CSIDriver Kubernetes API Object: Simplifies CSI driver discovery and allows CSI Drivers to customize Kubernetes behavior.

SIG Storage is also introducing the following new storage features as alpha in Kubernetes 1.18:
- Windows CSI Support: Enabling containerized CSI node plugins in Windows via new [CSIProxy](https://github.com/kubernetes-csi/csi-proxy)
- Recursive Volume Ownership OnRootMismatch Option: Add a new “OnRootMismatch” policy that can help shorten the mount time for volumes that require ownership change and have many directories and files.

### Other notable announcements

SIG Network is moving IPv6 to Beta in Kubernetes 1.18, after incrementing significantly the test coverage with new CI jobs.

NodeLocal DNSCache is an add-on that runs a dnsCache pod as a daemonset to improve clusterDNS performance and reliability. The feature has been in Alpha since 1.13 release. The SIG Network is announcing the GA graduation of Node Local DNSCache [#1351](https://github.com/kubernetes/enhancements/pull/1351)

## Known Issues

No Known Issues Reported

## Urgent Upgrade Notes

### (No, really, you MUST read this before you upgrade)

#### kube-apiserver:
- in an `--encryption-provider-config` config file, an explicit `cacheSize: 0` parameter previously silently defaulted to caching 1000 keys. In Kubernetes 1.18, this now returns a config validation error. To disable caching, you can specify a negative cacheSize value in Kubernetes 1.18+.
- consumers of the 'certificatesigningrequests/approval' API must now have permission to 'approve' CSRs for the specific signer requested by the CSR. More information on the new signerName field and the required authorization can be found at https://kubernetes.io/docs/reference/access-authn-authz/certificate-signing-requests#authorization ([#88246](https://github.com/kubernetes/kubernetes/pull/88246), [@munnerz](https://github.com/munnerz)) [SIG API Machinery, Apps, Auth, CLI, Node and Testing]
- The following features are unconditionally enabled and the corresponding `--feature-gates` flags have been removed: `PodPriority`, `TaintNodesByCondition`, `ResourceQuotaScopeSelectors` and `ScheduleDaemonSetPods` ([#86210](https://github.com/kubernetes/kubernetes/pull/86210), [@draveness](https://github.com/draveness)) [SIG Apps and Scheduling]

#### kubelet:
- `--enable-cadvisor-json-endpoints` is now disabled by default. If you need access to the cAdvisor v1 Json API please enable it explicitly in the kubelet command line. Please note that this flag was deprecated in 1.15 and will be removed in 1.19. ([#87440](https://github.com/kubernetes/kubernetes/pull/87440), [@dims](https://github.com/dims)) [SIG Instrumentation, Node and Testing]
- Promote CSIMigrationOpenStack to Beta (off by default since it requires installation of the OpenStack Cinder CSI Driver. The in-tree AWS OpenStack Cinder driver "kubernetes.io/cinder" was deprecated in 1.16 and will be removed in 1.20. Users should enable CSIMigration + CSIMigrationOpenStack features and install the OpenStack Cinder CSI Driver (https://github.com/kubernetes/cloud-provider-openstack) to avoid disruption to existing Pod and PVC objects at that time. Users should start using the OpenStack Cinder CSI Driver directly for any new volumes. ([#85637](https://github.com/kubernetes/kubernetes/pull/85637), [@dims](https://github.com/dims)) [SIG Cloud Provider]

#### kubectl:
- `kubectl` and k8s.io/client-go no longer default to a server address of `http://localhost:8080`. If you own one of these legacy clusters, you are *strongly* encouraged to secure your server. If you cannot secure your server, you can set the `$KUBERNETES_MASTER` environment variable to `http://localhost:8080` to continue defaulting the server address. `kubectl` users can also set the server address using the `--server` flag, or in a kubeconfig file specified via `--kubeconfig` or `$KUBECONFIG`.

#### client-go:
- Signatures on methods in generated clientsets, dynamic, metadata, and scale clients have been modified to accept `context.Context` as a first argument. Signatures of Create, Update, and Patch methods have been updated to accept CreateOptions, UpdateOptions and PatchOptions respectively. Signatures of Delete and DeleteCollection methods now accept DeleteOptions by value instead of by reference. Generated clientsets with the previous interface have been added in new "deprecated" packages to allow incremental migration to the new APIs. The deprecated packages will be removed in the 1.21 release. A tool is available at http://sigs.k8s.io/clientgofix to rewrite method invocations to the new signatures.

## Changelog since v1.18.0-beta.1

## Urgent Upgrade Notes

### (No, really, you MUST read this before you upgrade)

- `kubectl` no longer defaults to `http://localhost:8080`.  If you own one of these legacy clusters, you are *strongly- encouraged to secure your server.   If you cannot secure your server, you can set `KUBERNETES_MASTER` if you were relying on that behavior and you're a client-go user. Set `--server`, `--kubeconfig` or `KUBECONFIG` to make it work in `kubectl`. ([#86173](https://github.com/kubernetes/kubernetes/pull/86173), [@soltysh](https://github.com/soltysh)) [SIG API Machinery, CLI and Testing]

## Changelog since v1.18.0-beta.0

## Urgent Upgrade Notes

### (No, really, you MUST read this before you upgrade)

- The StreamingProxyRedirects feature and `--redirect-container-streaming` flag are deprecated, and will be removed in a future release. The default behavior (proxy streaming requests through the kubelet) will be the only supported option.
  If you are setting `--redirect-container-streaming=true`, then you must migrate off this configuration. The flag will no longer be able to be enabled starting in v1.20. If you are not setting the flag, no action is necessary. ([#88290](https://github.com/kubernetes/kubernetes/pull/88290), [@tallclair](https://github.com/tallclair)) [SIG API Machinery and Node]

- Feature Name: Support using network resources (VNet, LB, IP, etc.) in different AAD Tenant and Subscription than those for the cluster.
  
  Changes in Pull Request:
  
    1. Add properties `networkResourceTenantID` and `networkResourceSubscriptionID` in cloud provider auth config section, which indicates the location of network resources.
    2. Add function `GetMultiTenantServicePrincipalToken` to fetch multi-tenant service principal token, which will be used by Azure VM/VMSS Clients in this feature.
    3. Add function `GetNetworkResourceServicePrincipalToken` to fetch network resource service principal token, which will be used by Azure Network Resource (Load Balancer, Public IP, Route Table, Network Security Group and their sub level resources) Clients in this feature.
    4. Related unit tests.

Signatures of generated Create, Update, and Patch methods have been updated to accept CreateOptions, UpdateOptions and PatchOptions respectively. Clientsets that with the previous interface have been added in new "deprecated" packages to allow incremental migration to the new APIs. The deprecated packages will be removed in the 1.21 release. ([#87299](https://github.com/kubernetes/kubernetes/pull/87299), [@mikedanese](https://github.com/mikedanese)) [SIG API Machinery, Apps, Auth, Autoscaling, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Scheduling, Storage, Testing and Windows]
- The k8s.io/node-api component is no longer updated. Instead, use the RuntimeClass types located within k8s.io/api, and the generated clients located within k8s.io/client-go ([#87503](https://github.com/kubernetes/kubernetes/pull/87503), [@liggitt](https://github.com/liggitt)) [SIG Node and Release]

### Feature

- Add indexer for storage cacher ([#85445](https://github.com/kubernetes/kubernetes/pull/85445), [@shaloulcy](https://github.com/shaloulcy)) [SIG API Machinery]
- Add support for mount options to the FC volume plugin ([#87499](https://github.com/kubernetes/kubernetes/pull/87499), [@ejweber](https://github.com/ejweber)) [SIG Storage]
- Added a config-mode flag in azure auth module to enable getting AAD token without spn: prefix in audience claim. When it's not specified, the default behavior doesn't change. ([#87630](https://github.com/kubernetes/kubernetes/pull/87630), [@weinong](https://github.com/weinong)) [SIG API Machinery, Auth, CLI and Cloud Provider]

- Promote CSIMigrationOpenStack to Beta (off by default since it requires installation of the OpenStack Cinder CSI Driver)
  The in-tree AWS OpenStack Cinder "kubernetes.io/cinder" was already deprecated a while ago and will be removed in 1.20. Users should enable CSIMigration + CSIMigrationOpenStack features and install the OpenStack Cinder CSI Driver (https://github.com/kubernetes/cloud-provider-openstack) to avoid disruption to existing Pod and PVC objects at that time.
  Users should start using the OpenStack Cinder CSI Driver directly for any new volumes. ([#85637](https://github.com/kubernetes/kubernetes/pull/85637), [@dims](https://github.com/dims)) [SIG Cloud Provider]

### Design

- Fix regression in statefulset conversion which prevented applying a statefulset multiple times. ([#87706](https://github.com/kubernetes/kubernetes/pull/87706), [@liggitt](https://github.com/liggitt)) [SIG Apps, and SIG Testing]
- fixed two scheduler metrics (pending_pods and schedule_attempts_total) not being recorded ([#87692](https://github.com/kubernetes/kubernetes/pull/87692), [@everpeace](https://github.com/everpeace)) [SIG Scheduling]
- Resolved a performance issue in the node authorizer index maintenance. ([#87693](https://github.com/kubernetes/kubernetes/pull/87693), [@liggitt](https://github.com/liggitt)) [SIG Auth]
- Removed the 'client' label from apiserver_request_total. ([#87669](https://github.com/kubernetes/kubernetes/pull/87669), [@logicalhan](https://github.com/logicalhan)) [SIG API Machinery, and SIG Instrumentation]
- `(*"k8s.io/client-go/rest".Request).{Do,DoRaw,Stream,Watch}` now require callers to pass a `context.Context` as an argument. The context is used for timeout and cancellation signaling and to pass supplementary information to round trippers in the wrapped transport chain. If you don't need any of this functionality, it is sufficient to pass a context created with `context.Background()` to these functions. The `(*"k8s.io/client-go/rest".Request).Context` method is removed now that all methods that execute a request accept a context directly. ([#87597](https://github.com/kubernetes/kubernetes/pull/87597), [@mikedanese](https://github.com/mikedanese)) [SIG API Machinery, SIG Apps, SIG Auth, SIG Autoscaling, SIG CLI, SIG Cloud Provider, SIG Cluster Lifecycle, SIG Instrumentation, SIG Network, SIG Node, SIG Scheduling, SIG Storage, and SIG Testing]

- kubeadm: apply further improvements to the tentative support for concurrent etcd member join. Fixes a bug where multiple members can receive the same hostname. Increase the etcd client dial timeout and retry timeout for add/remove/... operations. ([#87505](https://github.com/kubernetes/kubernetes/pull/87505), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Reverted a kubectl azure auth module change where oidc claim spn: prefix was omitted resulting a breaking behavior with existing Azure AD OIDC enabled api-server ([#87507](https://github.com/kubernetes/kubernetes/pull/87507), [@weinong](https://github.com/weinong)) [SIG API Machinery, SIG Auth, and SIG Cloud Provider]
- Update cri-tools to v1.17.0 ([#86305](https://github.com/kubernetes/kubernetes/pull/86305), [@saschagrunert](https://github.com/saschagrunert)) [SIG Cluster Lifecycle, and SIG Release]
- kubeadm: remove the deprecated CoreDNS feature-gate. It was set to "true" since v1.11 when the feature went GA. In v1.13 it was marked as deprecated and hidden from the CLI. ([#87400](https://github.com/kubernetes/kubernetes/pull/87400), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Shared informers are now more reliable in the face of network disruption. ([#86015](https://github.com/kubernetes/kubernetes/pull/86015), [@squeed](https://github.com/squeed)) [SIG API Machinery]

## Changelog since v1.17.0

### Action Required

* action required ([#85363](https://github.com/kubernetes/kubernetes/pull/85363), [@immutableT](https://github.com/immutableT))
   1. Currently, if users were to explicitly specify CacheSize of 0 for KMS provider, they would end-up with a provider that caches up to 1000 keys. This PR changes this behavior.
      Post this PR, when users supply 0 for CacheSize this will result in a validation error.
   2. CacheSize type was changed from int32 to *int32. This allows defaulting logic to differentiate between cases where users explicitly supplied 0 vs. not supplied any value.
   3. KMS Provider's endpoint (path to Unix socket) is now validated when the EncryptionConfiguration files is loaded. This used to be handled by the GRPCService.
