Finally, any free program is threatened constantly by software patents.
We wish to avoid the danger that redistributors of a free program will
individually obtain patent licenses, in effect making the program
proprietary. To prevent this, we have made it clear that any patent must
be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and
modification follow.

* Ensure object returned by volume getCloudProvider incorporates cloud config ([#23769](https://github.com/kubernetes/kubernetes/pull/23769), [@saad-ali](https://github.com/saad-ali))
* Add a timeout to the sshDialer to prevent indefinite hangs. ([#23843](https://github.com/kubernetes/kubernetes/pull/23843), [@cjcullen](https://github.com/cjcullen))
