@aanm According to #16479 (comment) @pchaigno thinks this may be a different issue. I got the same Failed to retrieve iface by IP addr from error for two different test cases: (K8sDatapathConfig Encapsulation Check connectivity with VXLAN encapsulation and K8sDatapathConfig Encapsulation Check connectivity with Geneve encapsulation, see https://jenkins.cilium.io/job/Cilium-PR-K8s-1.19-kernel-5.4/738/). The error in #16479 is Failed to retrieve iface by IP addr: Failed to exec.

Hit it in #18031.

The cmd ip -j a s | jq -r '.[] | select(.addr_info[] | .local == \"192.168.56.11\") | .ifname' return empty string, while ip -j a s output seems to be correct (logged afterwards):

> cat /tmp/iface.json
