Description of problem: See https://github.com/kubernetes/kubernetes/issues/102480
Backport patch https://github.com/kubernetes/kubernetes/commit/b14bd44f33d93e1ee64c1d68fa7591d79eac5893 from 1.21.1 needs to be reverted (i.e. take https://github.com/kubernetes/kubernetes/pull/102587)
Version-Release number of selected component (if applicable): OpenShift 4.8 as of 1.21.1 rebase
Not reproducible in OpenShift because CRI-O does not vendor Kubernetes 1.21.1 yet: https://github.com/cri-o/cri-o/blob/478f49d4f5e005226ac7460edcb2ed21d804960f/go.mod#L99
Believe this only affects dockershim currently.
Containerd also has not yet updated code to the affected version: https://github.com/containerd/containerd/blob/261c107ffc4ff681bc73988f64e3f60c32233b37/pkg/cri/streaming/portforward/httpstream.go#L171
We want to back this out ASAP just to be safe.
Steps to Reproduce:
Note: OpenShift 4.7 and 4.6 are not affected, did not take the backports.
Not a release blocker because as far as we know there's no impact on OpenShift/CRI-O. This is a proactive backport of the upstream fix/revert before 4.8 freeze.
