Notes for BIND 9.16.1
|
|
---------------------
|
|
|
|
Known Issues
|
|
~~~~~~~~~~~~
|
|
|
|
- UDP network ports used for listening can no longer simultaneously be
|
|
used for sending traffic. An example configuration which triggers
|
|
this issue would be one which uses the same address:port pair for
|
|
``listen-on(-v6)`` statements as for ``notify-source(-v6)`` or
|
|
``transfer-source(-v6)``. While this issue affects all operating
|
|
systems, it only triggers log messages (e.g. "unable to create
|
|
dispatch for reserved port") on some of them. There are currently no
|
|
plans to make such a combination of settings work again.
|
|
|
|
Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- The system-provided POSIX Threads read-write lock implementation is
|
|
now used by default instead of the native BIND 9 implementation.
|
|
Please be aware that glibc versions 2.26 through 2.29 had a
|
|
`bug <https://sourceware.org/bugzilla/show_bug.cgi?id=23844>`__ that
|
|
could cause BIND 9 to deadlock. A fix was released in glibc 2.30, and
|
|
most current Linux distributions have patched or updated glibc, with
|
|
the notable exception of Ubuntu 18.04 (Bionic) which is a work in
|
|
progress. If you are running on an affected operating system, compile
|
|
BIND 9 with ``--disable-pthread-rwlock`` until a fixed version of
|
|
glibc is available. [GL !3125]

Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- Fixed re-signing issues with inline zones which resulted in records
|
|
being re-signed late or not at all.
