We now partly drop the support for seccomp annotations which is planned
for v1.25 as part of the KEP:
https://github.com/kubernetes/enhancements/issues/135
Pod security policies are not touched by this change and therefore we
have to keep the annotation key constants.
This means we only allow the usage of the annotations for backwards
compatibility reasons while the synchronization of the field to
annotation is no longer supported. Using the annotations for static pods
is also not supported any more.
Making the annotations fully non-functional will be deferred to a
future release.

GlusterFS is one of the first dynamic provisioner which made into
Kubernetes release v1.4.
https://github.com/kubernetes/kubernetes/pull/30888
When CSI plugins/drivers to start appear, glusterfs' CSI driver
came into existence, however this project is not maintianed at
present and the last release happened few years back.
https://github.com/gluster/gluster-csi-driver/releases/tag/v0.0.9
The possibilities of migration to compatible CSI driver was also
discussed https://github.com/kubernetes/kubernetes/issues/100897
and consensus was to start the deprecation in v1.25.
This commit start the deprecation process of glusterfs plugin from
in-tree drivers.

Terminal pods may continue to report a ready condition of true because
there is a delay in reconciling the ready condition of the containers
from the runtime with the pod status. It should be invalid for kubelet
to report a terminal phase with a true ready condition. To fix the
issue, explicitly override the ready condition to false for terminal
pods during status updates.

CSI spec 1.5 enhanced the spec to add optional secrets field to
NodeExpandVolumeRequest. This commit adds NodeExpandSecret to the
CSI PV source and also derive the expansion secret in csiclient to
send it out as part of the nodeexpand request.

Currently we only care about the sum of sandbox resources, which
includes a pod overhead if defined. We have a need for also calculating
*just* the sum of container requests/limits for CPU / Memory, so let's
do a refactor and expose this new helper function.

This fixes a bug where the test was dependent on the current set of
feature gates. Since AllFeatureEnabledContainers() depends on the
feature gates it must be evaluated after the test case is initialized.
The feature gate gets locked to "true", with the goal to remove it in two
releases.
All code now can assume that the feature is enabled. Tests for "feature
disabled" are no longer needed and get removed.
Some code wasn't using the new helper functions yet. That gets changed while
touching those lines.
Remove the VolumeSubpath feature gate.
Feature gate convention has been updated since this was introduced to
indicate that they "are intended to be deprecated and removed after a
feature becomes GA or is dropped.".
Headless+selectorless -> RequireDualStack
Headless+selector -> SingleStack
Add test cases to cover this and ExternalName and dual-stack init (which
I think can never trigger, but best to be safe).
This scaffolding allows us to assert more on each test case, and more
consistently.
Set input fields from output fields IFF they are expected AND not set on
input. This allows us to verify the "after" state (expected) whether
the test case specified the value or not, and still pass the generic
cmp.Equal.
Use this in a few tests to prove its worth, more to do.
Some of the existing tests that are focused on create and delete can
probably be replaced by these.
This could be used in other test cases that are open-coding a lot of the
same stuff. Later commits.
This includes a few cases.
1) TestCreateIgnoresIPFamilyForExternalName: Prove that ExternalName is
ignored for dual-stack. A small set of test cases were chosen to
demonstrate.
2) TestCreateIgnoresIPFamilyWithoutDualStack: Prove that when the
dual-stack gate is off, all services are ignored for dual-stack. A
small set of test cases were chosen to demonstrate
3) TestCreateInitIPFields: Run over a huge array of test cases for
dual-stack. This was generated by this program:
https://gist.github.com/thockin/cccc9c9a580b4830ee0946ddd43eeafe and
then updated by hand.
Prior to 1.22 a user could change NodePort values within a service
during an update, and the apiserver would allocate values for any that
were not specified.
Consider a YAML like:
```
apiVersion: v1
kind: Service
metadata:
name: foo
spec:
type: NodePort
ports:
- name: p
port: 80
- name: q
port: 81
selector:
app: foo
```
When this is created, nodeport values will be allocated for each port.
Something like:
```
apiVersion: v1
kind: Service
metadata:
name: foo
spec:
clusterIP: 10.0.149.11
type: NodePort
ports:
- name: p
nodePort: 30872
port: 80
protocol: TCP
targetPort: 9376
- name: q
nodePort: 31310
port: 81
protocol: TCP
targetPort: 81
selector:
app: foo
```
If the user PUTs (kubectl replace) the original YAML, we would see that
`.nodePort = 0`, and allocate new ports. This was ugly at best.
In 1.22 we fixed this to not allocate new values if we still had the old
values, but instead re-assign them. Net new ports would still be seen
as `.nodePort = 0` and so new allocations would be made.
This broke a corner case as follows:
Prior to 1.22, the user could PUT this YAML:
```
apiVersion: v1
kind: Service
metadata:
name: foo
spec:
type: NodePort
ports:
- name: p
nodePort: 31310 # note this is the `q` value
port: 80
- name: q
# note this nodePort is not specified
port: 81
selector:
app: foo
```
The `p` port would take the `q` port's value. The `q` port would be
seen as `.nodePort = 0` and a new value allocated. In 1.22 this results
in an error (duplicate value in `p` and `q`).
This is VERY minor but it is an API regression, which we try to avoid,
and the fix is not too horrible.
This commit adds more robust testing of this logic.
This patch adds removal warnings for the deprecated seccomp annotation,
which is targeting removal in v1.25.

It is not uncommon for users to Create a Service and not specify things
like ClusterIP and NodePort, which we then allocate for them. They same
that YAML somewhere and later use it again in an Update, but then it
fails.
That's because we detected them trying to set a ClusterIP from a value
to "", which is not allowed. If it was just NodePort, they would
actually succeed and reallocate a new port.
After this change, we try to "patch" updates where the user did not
specify those values from the old object.
Modify the behavior of the AnyVolumeDataSource alpha feature gate to enable
a new field, DataSourceRef, rather than modifying the behavior of the
existing DataSource field. This allows addition Volume Populators in a way
that doesn't risk breaking backwards compatibility, although it will
result in eventually deprecating the DataSource field.
Fixing this led to finding a bug in how the TestDropProbeGracePeriod
unit tests were written, so this patch also includes a fix for that.
