Use the new role :iscman: to replace all occurences or ``binary``
with :iscman:`binary`, creating a hyperlink to the manual page.
Generated using:
find bin -name *.rst | xargs fgrep --files-with-matches '.. iscman' | xargs -I{} -n1 basename {} .rst > /tmp/progs
for PROG in $(cat /tmp/progs); do find -name '*.rst' | xargs sed -i -e "s/\`\`$PROG\`\`/:iscman:\`$PROG\`/g"; done
Additional hand-edits were done mainly around filter-aaaa and
filter-a which are program names and and option names at the
same time. Couple more edits was neede to fix .rst syntax broken by
automatic replacement.

Notes for BIND 9.17.23
|
|
----------------------
|
|
|
|
Security Fixes
|
|
~~~~~~~~~~~~~~
|
|
|
|
- None.
|
|
|
|
Known Issues
|
|
~~~~~~~~~~~~
|
|
|
|
- None.
|
|
|
|
New Features
|
|
~~~~~~~~~~~~
|
|
|
|
- :iscman:`dnssec-verify` and :iscman:`dnssec-signzone` now accept a ``-J`` option to
|
|
specify a journal file to read when loading the zone to be verified or
|
|
signed. :gl:`#2486`
|
|
|
|
Removed Features
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
- The IPv6 sockets are now explicitly restricted to sending and receiving IPv6
|
|
packets only. This renders the :iscman:`dig` option ``+mapped`` non-functioning and
|
|
thus the option has been removed. :gl:`#3093`
|
|
|
|
- The ``keep-order-response`` option has been declared obsolete and the
|
|
functionality has been removed. :iscman:`named` expects DNS clients to be
|
|
fully compliant with :rfc:`7766`. :gl:`#3140`
|
|
|
|
Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- The DLZ API has been updated: EDNS Client-Subnet (ECS) options sent
|
|
by a client are now included in the client information sent to DLZ
|
|
modules when processing queries. :gl:`#3082`
|
|
|
|
- Add DEBUG(1) level messages when starting and ending BIND 9 task exclusive mode
|
|
that stops the normal DNS operation (f.e. for reconfiguration, interface
|
|
scans, and other events that require exclusive access to a shared resources).
|
|
:gl:`#3137`
|
|
|
|
- The limit on the number of simultaneously processed pipelined DNS queries
|
|
received over TCP has been dropped. Previously, it was capped at 23
|
|
queries processed at the same time. :gl:`#3141`
|
|
|
|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- With libuv >= 1.37.0, the recvmmsg support would not be enabled in :iscman:`named`
|
|
reducing the maximum query-response performance. The recvmmsg support would
|
|
be used only in libuv 1.35.0 and 1.36.0. This has been fixed. :gl:`#3095`
|
|
|
|
- A failed view configuration during a named reconfiguration procedure could
|
|
cause inconsistencies in BIND internal structures, causing a crash or other
|
|
unexpected errors. This has been fixed. :gl:`#3060`
|
|
|
|
- Restore logging "quota reached" message when accepting connection is over
|
|
hard quota. :gl:`#3125`
|
|
|
|
- Build errors were introduced in some DLZ modules due to an incomplete
|
|
change in the previous release. This has been fixed. :gl:`#3111`
|
|
|
|
- An error in the processing of the ``blackhole`` ACL could cause some DNS
|
|
requests sent by :iscman:`named` to fail - for example, zone transfer requests
|
|
and SOA refresh queries - if the destination address or prefix was
|
|
specifically excluded from the ACL using ``!``, or if the ACL was set
|
|
to ``none``. ``blackhole`` worked correctly when it was left unset, or
|
|
if only positive-match elements were included. This has now been fixed.
|
|
:gl:`#3157`
|
|
|
|
- TCP connections could hang indefinitely if the TCP write buffers
|
|
were full because of the other party not reading sent data. This has
|
|
been fixed by adding a "write" timer. Connections that are hung
|
|
while writing will now time out after the ``tcp-idle-timeout`` period
|
|
has elapsed. :gl:`#3132`
|
|
|
|
- Client TCP connections are now closed immediately when data received
|
|
cannot be parsed as a valid DNS request. :gl:`#3149`
|
|
|
|
- The ``max-transfer-time-out`` and ``max-transfer-idle-out`` options were
|
|
not implemented when the BIND 9 networking stack was refactored in 9.16.
|
|
The missing functionality has been re-implemented and outgoing zone
|
|
transfers now time out properly when not progressing. :gl:`#1897`
|
|
|
|
- The statistics counter representing the current number of clients
|
|
awaiting recursive resolution results (``RecursClients``) could be
|
|
miscalculated in certain resolution scenarios, potentially causing the
|
|
value of the counter to drop below zero. This has been fixed.
|
|
:gl:`#3147`
|
|
|
|
- Invalid dnssec-policy definitions were being accepted where the
|
|
defined keys did not cover both KSK and ZSK roles for a given
|
|
algorithm. This is now checked for and the dnssec-policy is
|
|
rejected if both roles are not present for all algorithms in use.
|
|
:gl:`#3142`
|
|
|
|
- Handling of the TCP write timeouts has been improved to track timeout
|
|
for each TCP write separately leading to faster connection tear down
|
|
in case the other party is not reading the data. :gl:`#3200`
