Description of problem:
Whereabouts doesn't allow the use of network interface names that are not preceded by the prefix "net", see https://github.com/k8snetworkplumbingwg/whereabouts/issues/130.
Version-Release number of selected component (if applicable):
How reproducible:
Always
Steps to Reproduce:
1. Define two Pods, one with the interface name 'port1' and the other with 'net-port1':
test-ip-removal-port1: k8s.v1.cni.cncf.io/networks: [ { "name": "test-sriovnd", "interface": "port1", "namespace": "default" } ] test-ip-removal-net-port1: k8s.v1.cni.cncf.io/networks: [ { "name": "test-sriovnd", "interface": "net-port1", "namespace": "default" } ]
2. IP allocated in the IPPool:
kind: IPPool ... spec: allocations: "16": id: ... podref: test-ecoloma-1/test-ip-removal-port1 "17": id: ... podref: test-ecoloma-1/test-ip-removal-net-port1
3. When the ip-reconciler job is run, the allocation for the port with the interface name 'port1' is removed:
[13:29][]$ oc get cronjob -n openshift-multus
NAME SCHEDULE SUSPEND ACTIVE LAST SCHEDULE AGE
ip-reconciler */15 * * * * False 0 14m 11d
[13:29][]$ oc get ippools.whereabouts.cni.cncf.io -n openshift-multus 2001-1b70-820d-2610---64 -o yaml
apiVersion: whereabouts.cni.cncf.io/v1alpha1
kind: IPPool
metadata:
...
spec:
allocations:
"17":
id: ...
podref: test-ecoloma-1/test-ip-removal-net-port1
range: 2001:1b70:820d:2610::/64
[13:30][]$ oc get cronjob -n openshift-multus
NAME SCHEDULE SUSPEND ACTIVE LAST SCHEDULE AGE
ip-reconciler */15 * * * * False 0 9s 11d
Actual results:
The network interface with a name that doesn't have a 'net' prefix is removed from the ip-reconciler cronjob.
Expected results:
The network interface must not be removed, regardless of the name.
