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
|
|
<replaceable>address:port</replaceable> pair for
|
|
<command>listen-on(-v6)</command> statements as for
|
|
<command>notify-source(-v6)</command> or
|
|
<command>transfer-source(-v6)</command>. 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.

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
|
|

|
|
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 <command>--disable-pthread-rwlock</command> until a fixed
|
|
version of glibc is available. [GL !3125]
