Go mod automatically ignores the /testdata directory.
This change ensures that the rootfs for source/pci tests are not
included in the module definition.

Disable AVX10 as unnecessary as AVX10_LEVEL is better suited for
checking AVX10 compatibility. There is not yet any hardware with the
feature so disabling it shouldn't cause problems for users.
Add new cpuid label "feature.node.kubernetes.io/cpu-cpuid.AVX10_VERSION"
that advertises the supported version of AVX10 vector ISA.
Correspondingly, the patch adds AVX10_VERSION to the "cpu.cpuid" feature
for NodeFeatureRules to consume.
This makes cpu.cpuid on amd64 architecture a "multi-type" feature in
that it contains "flags" and potentially also "attributes" (the only
cpuid attribute so far is the AVX10_VERSION).

Change the custom feature source of nfd-worker to use the newly added
internal config API for its own configuration. It now uses the internal
types for json/yaml unmarshalling but converts them to external
nfdv1alpha1 API to do the actual rule matching as the internal API does
not duplicate that functionality.
Add internal API for the nfd-worker custom feature source rule
configuration. This API has already diverged from the NFD
NodeFeatureRule API in that annotations, extended resources or taints
are not supported. This patch basically copies the Rule type (and it's
sub-types) from the nfdv1alpha1 package. It also adds conversion
functions from the internal rule API to the "external" nfdv1alpha1 API.
This is done to use the same rule matching functionality (from the
nfdv1alpha1 package).
One notable remark is that the feature source rule config supports some
custom formatting (short forms, multi-type fields) that relies on
special json/yaml unmarshalling functions that are better to nuke from
the nfdv1alpha1 package (in another patch). These (legacy) syntax
specialities are most probably used by nobody but let's keep them as
they're already there. Unit tests to cover the custom json
unmarshalling are now added.
Extend the format of feature matcher terms (the elements of the
arrayspecified under under matchFeatures field) with new matchName
field. The value of this field is an expression that is evaluated
against the names of feature elements instead of their values (values
are matched with the matchExpressions field, instead).
The matchName field is useful e.g. in template rules for creating
per-feature-element labels based on feature names (instead of values)
and in non-template rules for checking if (at least) one of certain
feature element names are present.
If both matchExpressions and matchName for certain feature matcher term
is specified, they both must match in order to get an overall match.
Also, in this case the list of matched features (used in templating) is
the union of the results from matchExpressions and matchName.
An example of creating an "avx512" label if any AVX512* CPUID feature is
present:
- name: "avx wildcard rule"
labels:
avx512: "true"
matchFeatures:
- feature: cpu.cpuid
matchName: {op: InRegexp, value: ["^AVX512"]}
An example of a template rule creating a dynamic set of labels based on
the existence of certain kconfig options.
- name: "kconfig template rule"
labelsTemplate: |
{{ range .kernel.config }}kconfig-{{ .Name }}={{ .Value }}
{{ end }}
matchFeatures:
- feature: kernel.config
matchName: {op: In, value: ["SWAP", "X86", "ARM"]}
NOTE: this patch changes the corner case of nil/null match expressions
with instance features (i.e. "matchExpressions: null"). Previously, we
returned all instances for templating but now a nil match expression is
not evaluated and no instances for templating are returned.
Drop the creation helper functions as one step in an effort to tidy up
the api package. These functions were not much used outside unit tests
anyway, the static rules of the nfd-worker custom feature source being
the only exception (and if those happened to be invalid we'd catch that
e.g. in the e2e-tests).
Drop the deprecated cpu-sgx.enabled and cpu-se.enabled labels and the
corresponding "raw" features. These have been replaced by
cpu-security.sgx.enabled and cpu-security.se.enabled.
