Patch from upstream

Description of problem:

For DNSSEC to be secure, dynamically modified zones must be kept separate from zones with static content. That requires the _acme-challenge name to be in its own, separate, dynamic zone. This is supported by the ACME protocol, but certbot 0.22.x or lower has a bug in this area.

THIS IS FIXED UPSTREAM IN CERTBOT 0.23.

The patch from the upstream repo (attached) can also be applied separately to the 0.22 codebase.

Version-Release number of selected component (if applicable):

python3-certbot-dns-rfc2136-0.22.2-1

How reproducible:

100%


Steps to Reproduce:

1. Set up a DNS structure with _acme-challenge as a separate modified zone
2. Try to configure it with certbot
3.

Actual results:

Error message

Expected results:

Zone update
