All distros I know of provide full source - GPL requires it for most
packages, and you would have a right to redistibute it, of
course.. This is no different than the kernel.

Right, that is what I ment when I said 'latest rdma-core'

The very best thing you can do for your cusomters is to provide your
changes in a way that the distro itself would be willing to backport
and release as a minor update to their users. eg provide clear commit
messages, a fixes tag, content that is appropriate for stable
backporting and inform the distro via your corporate relationship to
take the patch. This is what Leon is talking about.

This is no different than the process for the kernel.
