Just print a warning instead of exiting with an error if no version has
been specified at build-time. This was pointless and just annoying at
development time when doing builds with go directly.
This adds support for making selected labels extended resources.
Labels which have integer values, can be promoted to Kubernetes extended
resources by listing them to the added command line flag
`--resource-labels`. These labels won't then show in the node label
section, they will appear only as extended resources.

- Implement the 'custom' feature source utilizing the
match rules implemented in previous commit.
- Add a static custom feature list for:
1. rdma.capable - marks a node where devices that support
RDMA are present.
2. rdma.enabled - marks a node where rdma modules have
been loaded.
A user may extend these features with additional match rules via
NFD configuration file.
- Add a Rule interface to help describe the contract
between a match rule and the Custom source that uses it.
- Add PciIdRule - a rule that matches on the PCI attributes:
class, vendor, device. Each is provided as a list of elements(strings).
Match operation: OR will be performed per element and AND will be
performed per attribute.
An empty attribute will not be included in the matching process.
Example:
{
"class": ["0200"]
"vendor": ["15b3"]
"device": ["1014", "1016"]
}
- Add LoadedKmodRule - a rule that matches a list of kernel
modules with the kernel modules currently loaded in the node.
Example:
{
["rdma_cm", "ib_core"]
}
This will enable code reuse across sources while preventing
packages which are not under 'source' to import it.
subsequent commits will introduce the 'custom' source which
will use the logic.
Use the contents of 'E2E_TEST_CONFIG_DATA' environment variable as the
e2e-test-config, enabling wider end-to-end test converage (assuming
E2E_TEST_CONFIG_DATA is properly populated).
Implement an end-to-end test with all feature sources enabled. The new
test runs nfd-worker as a daemonset on all (schedulable) nodes of the
test cluster which makes it possible to cover a wide range features,
assuming the test cluster is heterogenous containing nodes with varying
system configurations.
The features available depends on the node(s) the e2e testa are run on.
Thus, some runtime parameterization of the tests is needed. The patch
adds a new command line test flag 'nfd.e2e-config' that is used to
specify the per-node feature labels and annotations that is expected to
be present in the cluster. An example configuration file is provided
with the patch. The pod spec of nfd-worker deployment is changed to
better correspond the default deployment and thus enable wider feature
discovery. This means using hostnetwork and adding mounts for /sys /boot
and /etc/os-release.
The patch changes node object management so that all nfd-related labels
are removed after each test (not just the ones the test is expected to
add). Also, all nfd-related annotations are now removed.
SR-IOV is a PCI attribute and also non-NIC PCI devices can have it. Therefore,
it is useful to label all PCI devices with that capability.
After this commit the following labels for Intel NICs are overlapping:
feature.node.kubernetes.io/pci-0200_8086.sriov.capable=true
feature.node.kubernetes.io/network-sriov.capable=true

Assumes the test cluster to be hosted in AWS. The following environment
variables need to be properly configured in the CI in order to
successfully run the tests:
AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY
AWS_REGION
KUBECONFIG_AWS
Also, the following are probably needed in order for the script to be be
able to push the container image to the remote registry:
IMAGE_REPO
IMAGE_REPO_PASSWORD
IMAGE_REPO_USER
Speeds up local builds considerably as the deps are cached (instead of
downloading them all on every build) - as long as go.mod and go.sum are
not changed.
Due to the constraint, pretty old version is being used. Update
the cpuid package to the latest master to get, e.g., AVX512_VNNI
and VMX detection.
