Hi @artemvmin. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

You may be able to get rid of the replace statement if you put 0.24.1 here

I already tried that and wrestled with this for a while:

I believe that means that some of our dependencies need us to specify the version via replace.

Looks like v11.0.1-0.20190805182717-6502b5e7b1b5+incompatible is arbitrary and doesn't show up in our go.sum file. Pulling the latest version is just a way for go mod tidy to satisfy the require directive syntax.

We need to be careful with updating compute-gen.go.

We had to manually update it for hyperdisk work https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/commits/master/vendor/google.golang.org/api/compute cc @sunnylovestiramisu

sunnylovestiramisu · 2023-03-09T21:29:44Z

Please do not update the compute-gen.go via go mod tidy/vendor. It will remove the hyperdisk feature support. :(

@msau42 I had to add this because of two breaking changes that updated the interface. Could you confirm that it's safe to use the upstream implementation?

https://github.com/kubernetes/mount-utils/blob/master/mount_windows.go#L247-L259

Until we switch to Windows host process #1071, we may not be able to do many mount operations directly. @mauriciopoppe can you confirm?

This file only uses the following exported properties from k8s.io/mount-utils:

mount.NormalizeWindowsPath (method)

mount.MountPoint (struct)

None of these paths use these two methods. I believe it's safe to use the upstream implementation, in Windows we're not doing mount directly yet because #1071 isn't merged, if #1071 is merged these two paths won't be used still.

Does this also fix the CVE-2022-41723? It needs golang.org/x/net update.

If yes, please add this CVE fix information to the release note.

Done! Nice catch.

@sunnylovestiramisu Could you please elaborate? I don't see how this would break hyperdisk. All e2e tests are passing.

I have also confirmed that the generated compute-gen.go is the 2023 version, which includes Disk.ProvisionedThroughput.

We also shouldn't be manually replacing vendor files. The desired effect in af3994a can be achieved by updating https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/blob/master/go.mod#L6 to a newer version. Was the new version not available when we were doing hyperdisk integration?

Maybe we could write the patch to the directory vendor-patches/ to know that this has to be applied to vendor. A check in presubmit would be to have a clean download of vendor/ + applying vendor-patches and this could be diffed with the presubmit vendor/.

Confirmed with the PD team that the current beta model has the hyperdisk fields
