12Notes for BIND 9.18.15
13----------------------
14
15Bug Fixes
16~~~~~~~~~
17
18- The :any:`max-transfer-time-in` and :any:`max-transfer-idle-in`
19  statements have not had any effect since the BIND 9 networking stack
20  was refactored in version 9.16. The missing functionality has been
21  re-implemented and incoming zone transfers now time out properly when
22  not progressing. :gl:`#4004`
23
24- The read timeout in :iscman:`rndc` is now 60 seconds, matching the
25  behavior in BIND 9.16 and earlier. It had previously been lowered to
26  30 seconds by mistake. :gl:`#4046`
27
28- When the ``ISC_R_INVALIDPROTO`` (``ENOPROTOOPT``, ``EPROTONOSUPPORT``)
29  error code is returned by libuv, it is now treated as a network
30  failure: the server for which that error code is returned gets marked
31  as broken and is not contacted again during a given resolution
32  process. :gl:`#4005`
33
34- When removing delegations from an opt-out range, empty-non-terminal
35  NSEC3 records generated by those delegations were not cleaned up. This
36  has been fixed. :gl:`#4027`
37
38- Log file rotation code did not clean up older versions of log files
39  when the logging :any:`channel` had an absolute path configured as a
40  ``file`` destination. This has been fixed. :gl:`#3991`
41
42Known Issues
43~~~~~~~~~~~~
44
45- Sending NOTIFY messages silently fails when the source port specified
46  in the :any:`notify-source` statement is already in use. This can
47  happen e.g. when multiple servers are configured as NOTIFY targets for
48  a zone and some of them are unresponsive. This issue can be worked
49  around by not specifying the source port for NOTIFY messages in the
50  :any:`notify-source` statement; note that source port configuration is
51  already `deprecated`_ and will be removed altogether in a future
52  release. :gl:`#4002`
53
54- See :ref:`above <relnotes_known_issues>` for a list of all known
55  issues affecting this BIND 9 branch.
