[k8s 1.32/golang 1.23] Breaking changes for CSI drivers on Windows

[Michelle Au]

Hi everyone,

golang 1.23 has made some significant changes to how Windows mount points are reported. We are still evaluating the impact, so until we fully understand what fixes we may need to make, CSI drivers and csi-proxy should either:

1. Hold off on upgrading to golang 1.23 until we provide further guidance. This also means refraining from updating k8s.io/mount-utils to v0.32.0

2. If upgrading to golang 1.23, add the "godebug winsymlink=0" flag to the go.mod file to disable these changes.

See https://github.com/kubernetes/kubernetes/issues/129080 for more details.

Thanks,

Michelle

Thanks for sharing, there's an equivalent k8s.io/mount-utils binary for Windows called CSI Proxy which uses the go filesystem API. I recently saw a PR that's a sync from CSI release tools that bumped the go runtime to 1.23. I'm following option 2 through https://github.com/kubernetes-csi/csi-proxy/pull/363 to use set the min go version to 1.23 and to have `godebug winsymlink=0` in go.mod.

Best,

Mauricio
