https://fedoraproject.org/wiki/Changes/BIND_9.18

This document represents a proposed Change. As part of the Changes
process, proposals are publicly announced in order to receive
community feedback. This proposal will only be implemented if approved

== Summary ==
(not provided)

== Owner ==
* Name: [[User:pemensik| Petr Menšík]]
* Email: <pemensik(a)redhat.com&gt;


== Detailed Description ==
ISC BIND9 will be upgraded to new major release version 9.18.x. It
introduces new features and changes. It will also remove some packages
provided before.


== Benefit to Fedora ==
The most recent major release will be provided, with some notable features:

* Support to DNS over TLS and DNS over HTTPS servers. Both
authoritative and resolver modes.
* Reworked internal connection handling using libuv
* RNDC channel does not support unix sockets
[https://gitlab.isc.org/isc-projects/bind9/-/issues/1759]
* Zone transfers over
[https://datatracker.ietf.org/doc/html/rfc9103.html 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


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

* Other developers: Any developers
* Change pull request:
[https://src.fedoraproject.org/rpms/bind/pull-request/13 bind PR#13]

* Release engineering:
* Policies and guidelines: N/A (not needed for this Change)
* Trademark approval: N/A (not needed for this Change)
* Alignment with Objectives:


== 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
[https://bind9.readthedocs.io/en/v9_18_4/reference.html#dnssec-policy-grammar
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.

=== Removed options ===

Previously deprecated options were removed and are no longer accepted
in ''/etc/named.conf''. Their full list can be found on
[https://bind9.readthedocs.io/en/v9_18_4/notes.html#removed-features
removed features] release notes in Upstream.

== How To Test ==
(not supplied)


== 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.

== Contingency Plan ==
* Contingency mechanism: (What to do?  Who will do it?) N/A (not a
System Wide Change)
* Contingency deadline: N/A (not a System Wide Change)
* Blocks release? N/A (not a System Wide Change), Yes/No


== Documentation ==
N/A (not a System Wide Change)
