Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- The new networking code introduced in BIND 9.16 (netmgr) was
|
|
overhauled in order to make it more stable, testable, and
|
|
maintainable. [GL #2321]
|
|
|
|
- Earlier releases of BIND versions 9.16 and newer required the
|
|
operating system to support load-balanced sockets in order for
|
|
``named`` to be able to achieve high performance (by distributing
|
|
incoming queries among multiple threads). However, the only operating
|
|
systems currently known to support load-balanced sockets are Linux and
|
|
FreeBSD 12, which means both UDP and TCP performance were limited to a
|
|
single thread on other systems. As of BIND 9.17.8, ``named`` attempts
|
|
to distribute incoming queries among multiple threads on systems which
|
|
lack support for load-balanced sockets (except Windows). [GL #2137]
|
|
|
|
- When using the ``unixtime`` or ``date`` method to update the SOA
|
|
serial number, ``named`` and ``dnssec-signzone`` silently fell back to
|
|
the ``increment`` method to prevent the new serial number from being
|
|
smaller than the old serial number (using serial number arithmetics).
|
|
``dnsssec-signzone`` now prints a warning message, and ``named`` logs
|
|
a warning, when such a fallback happens. [GL #2058]
