Several packages are only used while running the e2e suite. These packages are less important to update, as the they can not influence the final executable that is part of the Ceph-CSI container-image. By moving these dependencies out of the main Ceph-CSI go.mod, it is easier to identify if a reported CVE affects Ceph-CSI, or only the testing (like most of the Kubernetes CVEs).

// readerWrapper delegates to an io.Reader so that only the io.Reader interface is implemented,

// to keep io.Copy from doing things we don't want when copying from the reader to the data stream.
|

//
|
|
// If the Stdin io.Reader provided to remotecommand implements a WriteTo function (like bytes.Buffer does[1]),
|
|
// io.Copy calls that method[2] to attempt to write the entire buffer to the stream in one call.
|
|
// That results in an oversized call to spdystream.Stream#Write [3],
|
|
// which results in a single oversized data frame[4] that is too large.
