- RNDC channel does not support unix sockets [1]
- Zone transfers over DNS over TLS were added, both incoming and outgoing.
- dig is now able to send queries using DNS over TLS
- dig is now able to send queries using DNS over HTTPS

- Proposal owners:
- The update required update of bind-dyndb-ldap package (part of Freeipa suite), but otherwise it is isolated change.

Upgrade/compatibility impact
Upgrade should be smooth from 9.16.x, without significant issues. Incompatibility existed with bind-dyndb-ldap, but that were resolved.
PKCS11 removal
Native PKCS11 builds in separate bind-pkcs11 package and bind-pkcs11-utils will be not longer built. It used to read directly pkcs11 plugins, but it will be supported only indirectly using OpenSSL pkcs11 engine.
Following commands would be removed:
- pkcs11-keygen
- pkcs11-destroy
- pkcs11-list
- pkcs11-tokens
All their actions should be possible using pkcs11-tool from opensc package or p11tool from gnutls-utils package.
- dnssec-*-pkcs11 commands would be removed too, but they have simple replacement using -E pkcs11 parameter to their respective normal dnssec-* tool.
Python isc module
The utilities dnssec-checkds, dnssec-coverage, and dnssec-keymgr have been removed from bind-dnssec-utils package. Also python3-bind python module is no longer supported by ISC upstream and therefore removed from a bind package. DNSSEC features formerly provided by these utilities are now integrated into named. See the dnssec-policy configuration option for more details.
Map file format
Support for the map zone file format (masterfile-format map;) has been removed. Use raw format instead, which has similar performance and less issues. Use named-compilezone -f map -F raw tool to convert the zone to raw format before the upgrade.
Removed options
Previously deprecated options were removed and are no longer accepted in /etc/named.conf. Their full list can be found on removed features release notes in Upstream.
How To Test
User Experience
- Users will get simple tools to query also encrypted DNS servers.
- Recent improvements packaged.
- Simplified DNSSEC maintenance of both keys and signatures via dnssec-policy
Dependencies
bind-dyndb-ldap would be built together with bind package. It were upgraded to version 11.10 to support BIND 9.18 release.
