Update mocked implementation of
k8s.io/kubelet/pkg/apis/podresources/v1.PodResourcesListerClient. The
mocked implementation is moved to a separate "mocks" subpackage as it's
for an external interface.
This patch also adds code for auto-generation for the mocked interface.
Eliminate all context.TODO() from the e2e tests and use ginkgo context
instead. This ensures that calls involving context are properly
cancelled and return fast in case the tests get aborted.
This patch add SEV ASIDs and the related (but distinct) SEV Encrypted State
(SEV-ES) IDs as two quantities to be exposed via extended resources.
In a kernel built with CONFIG_CGROUP_MISC on a suitably equipped AMD CPU, the
root control group will have a misc.capacity file that shows the number of
available IDs in each category.
The added extended resources are:
- sev.asids
- sev.encrypted_state_ids

Previously we were using the default, which even if equal to 0, still
means 10 minute timout in practice (with the way we run the tests with
invoking go test directly). With the addition of latest e2e tests we
hit the limit and got bitten by it. Set the timeout to 1 hour which
should be enough for anyone...
Change the NFD API handler to re-try on node update failures. Will work
around transient failures, making sure that failed nodes (i.e. nodes
that we failed to update) don't need to wait for the 1 hour resync
period before being tried again.
This PR adds the combination of dynamic and builtin kernel modules into
one feature called `kernel.enabledmodule`. It's a superset of the
`kernel.loadedmodule` feature.

Mark the -resource-labels flag (and the corresponding resourceLabels
config option) as deprecated. We now support managing extended resources
via NodeFeatureRule objects. This kludge deserves to go, eventually.
Increase the NFD API controller resync period from 5 minutes to 1 hour.
The resync causes nfd-master to replay all NodeFeature and
NodeFeatureRule objects, being effectively a "big hammer reset all"
button. This should only be needed as an "insurance" to fix labels et al
in case they have been manually tampered (outside NFD) and against
certain bugs in nfd itself. NFD is not supposed to manage anything
fast-changing so 1 hour should be enough.
This change only affects behavior when the NodeFeature API has been
enabled (with -enable-nodefeature-api).
Add support for management of Extended Resources via the
NodeFeatureRule CRD API.
There are usage scenarios where users want to advertise features
as extended resources instead of labels (or annotations).
This patch enables the discovery of extended resources, via annotation
and patch of node.status.capacity and node.status.allocatable. By using
the NodeFeatureRule API.

Update node status before node metadata. This fixes a problem where we
lose track of NFD-managed extended resources in case patching node
status fails. Previously we removed all labels and annotations
(including the one listing our ERs) and only after that updated node
status. If node status update failed we had lost the annotation but
extended resources were still there, leaving them orphaned.
Disallow taints having a key with "kubernetes.io/" or "*.kubernetes.io/"
prefix. This is a precaution to protect the user from messing up with
the "official" well-known taints from Kubernetes itself. The only
exception is that the "nfd.node.kubernetes.io/" prefix is allowed.
However, there is one allowed NFD-specific namespace (and its
sub-namespaces) i.e. "feature.node.kubernetes.io" under the
kubernetes.io domain that can be used for NFD-managed taints.
Also disallow unprefixed taint keys. We don't add a default prefix to
unprefixed taints (like we do for labels) from NodeFeatureRules. This is
to prevent unpleasant surprises to users that need to manage matching
tolerations for their workloads.
Make the default master pod run with no special options. Move the
customizations of the master pod to the setup functions of the tests
that actually need it.
Also, cleanup the configuration of nfd-worker of some tests.
Wait for the deletion of NFD CRDs to complete before trying to re-create
them. Prevents errors in case CRDs already exist on the cluster when
e2e-tests are launched.
