New Features

|
~~~~~~~~~~~~
|
|
|
|
- Add a new ``rndc`` command, ``rndc dnssec -rollover``, which triggers
|
|
a manual rollover for a specific key. [GL #1749]
|
|
|
|
- New ``rndc`` command ``rndc dumpdb -expired`` that dumps the cache database
|
|
to the dump-file including expired RRsets that are awaiting cleanup, for
|
|
diagnostic purposes. [GL #1870]

Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- [DNS Flag Day 2020]: The default EDNS buffer size has been changed from 4096
|
|
to 1232. According to the measurements done by multiple parties this should
|
|
not be causing any operational problems as most of the Internet "core" is able
|
|
to cope with IP message sizes between 1400-1500 bytes, the 1232 size was
|
|
picked as a conservative minimal number that could be changed by the DNS
|
|
operator to a estimated path MTU minus the estimated header space. In
|
|
practice, the smallest MTU witnessed in the operational DNS community is 1500
|
|
octets, the Ethernet maximum payload size, so a a useful default for maximum
|
|
DNS/UDP payload size on reliable networks would be 1400. [GL #2183]
|

|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- Updating contents of an RPZ zone which contained names spelled using
|
|
varying letter case could cause some processing rules in that RPZ zone
|
|
to be erroneously ignored. [GL #2169]
|
|
|
|
- `named` would report invalid memory size when running in an environment
|
|
that doesn't properly report number of available memory pages or pagesize.
|
|
[GL #2166]
|
|
|
|
- `named` would exit with assertion failure REQUIRE(msg->state == (-1)) in
|
|
message.c due to a possible data race. [GL #2124]
|
|
|
|
- `named` would start continous rollovers for policies that algorithms
|
|
Ed25519 or Ed448 due to a mismatch in created key size and expected key size.
|
|
[GL #2171]
