OCPBUGS-109578: proof pr to bump library-go to fix oc macos hcp insecure login - #2391
ehearne-redhat wants to merge 2 commits into
Conversation
This commit bumps library-go to include the latest changes. This fixes an issue seen when oc client is used to login to a HCP cluster on macOS. This allows oc to login successfully. `verifyServerCertChain()` now has a check that returns an unknown authority error when it detects macOS and a string based x509 error. It falls back to kubeconfig CA when a string based x509 error is observed on the macOS platform.

This fix resolves a major issue introduced in a recent change where logging in using oc on macos to a hcp client with insecure flag was used. On other clusters where there was no error, the check now panics on strings.HasPrefix(err.Error(), ...) as there was no check to see if err != nil. This was flagged by coderabbitai in library-go bump pr in oc. openshift/oc#2391 (comment) This change move darwin cert verify logic out of verifyServerCertChain, and additionally, adds a unit test that actually tests the error logic for darwin based systems.

This commit also simplifies the error checking process by wrapping the error in a custom error for better readability. it also simplifies the error checking and unit tests for this problem. It does this by moving the error conversion and error check for the unknown x509 error type to the default switch case. this should mitigate the concern about error type conversions when all other typed error checks have not been exhausted. by moving it further down, we can ensure the error stays intact only until we have exhausted already existing typed error checks. at this stage we can assume the error in question is likely the string based x5099 unknown error which we can convert to the desired type.

Do not keep the fork as the long-term production dependency.
This replacement executes forked code in the oc binary. The pinned pseudo-version and go.sum checksums protect the downloaded bytes, but they do not establish upstream authorization or signed release provenance. Keep the fork behind the proof-PR gate, then switch to the merged upstream revision before release and generate the required SBOM and provenance attestation.
