Are all bugs discovered pushed upstream?

@biapalmeiro, Could you clarify your question?

Did you mean something like: Are issues filed for bugs here, https://github.com/clearlinux/distribution, and addressed on upstream/mainline?

Well, yes, discovered upstream bugs are pushed back to upstream packages.

I can not tell which of them are not pushed upstream, but usually all
are pushed back to upstream. Even more some enhancement are pushed to
upstream too.
