- Update to release 9.18.13
New Features:
* RPZ updates are now run on specialized “offload” threads to
reduce the amount of time they block query processing on the
main networking threads. This increases the responsiveness of
named when RPZ updates are being applied after an RPZ zone has
been successfully transferred.
Feature Changes:
* Catalog zone updates are now run on specialized “offload”
threads to reduce the amount of time they block query
processing on the main networking threads. This increases the
responsiveness of named when catalog zone updates are being
applied after a catalog zone has been successfully transferred.
* libuv support for receiving multiple UDP messages in a single
recvmmsg() system call has been tweaked several times between
libuv versions 1.35.0 and 1.40.0; the current recommended libuv
version is 1.40.0 or higher. New rules are now in effect for
running with a different version of libuv than the one used at
compilation time. These rules may trigger a fatal error at
startup:
- Building against or running with libuv versions 1.35.0 and
1.36.0 is now a fatal error.
- Running with libuv version higher than 1.34.2 is now a
fatal error when named is built against libuv version
1.34.2 or lower.
- Running with libuv version higher than 1.39.0 is now a
fatal error when named is built against libuv version
1.37.0, 1.38.0, 1.38.1, or 1.39.0.
* This prevents the use of libuv versions that may trigger an
assertion failure when receiving multiple UDP messages in a
single system call.
Bug Fixes:
* named could crash with an assertion failure when adding a new
zone into the configuration file for a name which was already
configured as a member zone for a catalog zone. This has been
fixed.
* When named starts up, it sends a query for the DNSSEC key for
each configured trust anchor to determine whether the key has
changed. In some unusual cases, the query might depend on a
zone for which the server is itself authoritative, and would
have failed if it were sent before the zone was fully loaded.
This has now been fixed by delaying the key queries until all
zones have finished loading.
