Automatic merge from submit-queue [WIP] Skip resize of nf_conntrack/parameters/hashsize if not necessary **What this PR does / why we need it**: Linux does not support writing to `/sys/module/nf_conntrack/parameters/hashsize` when the writer process is not in the initial network namespace (https://github.com/torvalds/linux/blob/v4.10/net/netfilter/nf_conntrack_core.c#L1795-L1796). Usually that's fine. But in some configurations such as with https://github.com/kinvolk/kubeadm-nspawn, kube-proxy is in another netns. Therefore, check if writing in hashsize is necessary and skip the writing if not. **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes # **Special notes for your reviewer**: **Release note**: ```release-note ``` |
