Notes for BIND 9.17.11
|
|
----------------------
|
|
|
|
New Features
|
|
~~~~~~~~~~~~
|
|
|
|
- ``dig`` has been extended to support DNS-over-HTTPS (DoH) queries,
|
|
using ``dig +https`` and related options. [GL #1641]
|
|
|
|
- A new ``purge-keys`` option has been added to ``dnssec-policy``. It
|
|
sets the period of time that key files are retained after becoming
|
|
obsolete due to a key rollover; the default is 90 days. This feature
|
|
can be disabled by setting ``purge-keys`` to 0. [GL #2408]
|
|
|
|
Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- To prevent users from inadvertently configuring unencrypted
|
|
DNS-over-HTTPS (DoH) in BIND 9, ``listen-on`` and ``listen-on-v6``
|
|
statements using the ``http`` parameter must now also specify the
|
|
``tls`` parameter. ``tls none`` can be used to explicitly allow
|
|
unencrypted HTTP connections. [GL #2472]
|
|
|
|
- ``http default`` can now be specified in ``listen-on`` and
|
|
``listen-on-v6`` statements to use the default HTTP endpoint of
|
|
``/dns-query``. It is no longer necessary to include an ``http``
|
|
statement in ``named.conf`` unless overriding this value. [GL #2472]
|
|
|
|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- Zone journal (``.jnl``) files created by versions of ``named`` prior
|
|
to 9.16.12 were no longer compatible; this could cause problems when
|
|
upgrading if journal files were not synchronized first. This has been
|
|
corrected: older journal files can now be read when starting up. When
|
|
an old-style journal file is detected, it is updated to the new format
|
|
immediately after loading.
|
|
|
|
Note that journals created by the current version of ``named`` are not
|
|
usable by versions prior to 9.16.12. Before downgrading to a prior
|
|
release, users are advised to ensure that all dynamic zones have been
|
|
synchronized using ``rndc sync -clean``.
|
|
|
|
A journal file's format can be changed manually by running
|
|
``named-journalprint -d`` (downgrade) or ``named-journalprint -u``
|
|
(upgrade). Note that this *must not* be done while ``named`` is
|
|
running. [GL #2505]
|
|
|
|
- ``named`` crashed when it was allowed to serve stale answers and
|
|
``stale-answer-client-timeout`` was triggered without any (stale) data
|
|
available in the cache to answer the query. [GL #2503]
|
|
|
|
- If an outgoing packet exceeded ``max-udp-size``, ``named`` dropped it
|
|
instead of sending back a proper response. To prevent this problem,
|
|
the ``IP_DONTFRAG`` option is no longer set on UDP sockets, which has
|
|
been happening since BIND 9.17.6. [GL #2466]
|
|
|
|
- NSEC3 records were not immediately created when signing a dynamic zone
|
|
using ``dnssec-policy`` with ``nsec3param``. This has been fixed.
|
|
[GL #2498]
|
|
|
|
- A memory leak occurred when ``named`` was reconfigured after adding an
|
|
inline-signed zone with ``auto-dnssec maintain`` enabled. This has
|
|
been fixed. [GL #2041]
|
|
|
|
- An invalid direction field (not one of ``N``, ``S``, ``E``, ``W``) in
|
|
a LOC record resulted in an INSIST failure when a zone file containing
|
|
such a record was loaded. [GL #2499]
|
|
|
|
- If an invalid key name (e.g. ``a..b``) was specified in a
|
|
``primaries`` list in ``named.conf``, the wrong size was passed to
|
|
``isc_mem_put()``, which resulted in the returned memory being put on
|
|
the wrong free list and prevented ``named`` from starting up. This has
|
|
been fixed. [GL #2460]
|
|
|
|
- ``libtool`` was inadvertently introduced as a build-time requirement
|
|
when the build system was revamped in BIND 9.17.2. This unnecessarily
|
|
prevented hosts without that tool from building BIND 9 from source
|
|
tarballs. A standalone ``libtool`` script no longer needs to be
|
|
present in ``PATH`` to build BIND 9 from a source tarball. [GL #2504]
