Root and + top-level domain servers are no longer exempt from the + ``max-recursion-queries`` limit. Fetches for missing name server + address records are limited to 4 for any domain. This issue was + disclosed in CVE-2020-8616. :gl:`#1388` + +- Replaying a TSIG BADTIME response as a request could trigger an + assertion failure. This was disclosed in CVE-2020-8617. :gl:`#1703` + +Known Issues +~~~~~~~~~~~~ + +- BIND crashes on startup when linked against libuv 1.36. This issue + is related to ``recvmmsg()`` support in libuv, which was first + included in libuv 1.35. The problem was addressed in libuv 1.37, but + the relevant libuv code change requires a special flag to be set + during library initialization in order for ``recvmmsg()`` support to + be enabled. This BIND release sets that special flag when required, + so ``recvmmsg()`` support is now enabled when BIND is compiled + against either libuv 1.35 or libuv 1.37+; libuv 1.36 is still not + usable with BIND. :gl:`#1761` :gl:`#1797` + +- See :ref:`above <relnotes_known_issues>` for a list of all known + issues affecting this BIND 9 branch. + +Feature Changes +~~~~~~~~~~~~~~~ + +- BIND 9 no longer sets receive/send buffer sizes for UDP sockets, + relying on system defaults instead. :gl:`#1713` + +- The default rwlock implementation has been changed back to the native + BIND 9 rwlock implementation. :gl:`#1753` + +- The native PKCS#11 EdDSA implementation has been updated to PKCS#11 + v3.0 and thus made operational again. Contributed by Aaron Thompson. + :gl:`!3326` + +- The OpenSSL ECDSA implementation has been updated to support PKCS#11 + via OpenSSL engine (see engine_pkcs11 from libp11 project). + :gl:`#1534` + +- The OpenSSL EdDSA implementation has been updated to support PKCS#11 + via OpenSSL engine. Please note that an EdDSA-capable OpenSSL engine + is required and thus this code is only a proof-of-concept for the + time being. Contributed by Aaron Thompson. :gl:`#1763` + +- Message IDs in inbound AXFR transfers are now checked for + consistency. Log messages are emitted for streams with inconsistent + message IDs. :gl:`#1674` + +- The zone timers are now exported to the statistics channel. For the + primary zones, only the loaded time is exported. For the secondary + zones, the exported timers also include expire and refresh times. + Contributed by Paul Frieden, Verizon Media. :gl:`#1232` + +Bug Fixes +~~~~~~~~~ + +- A bug in dnstap initialization could prevent some dnstap data from + being logged, especially on recursive resolvers. :gl:`#1795` + +- When running on a system with support for Linux capabilities, + ``named`` drops root privileges very soon after system startup. This + was causing a spurious log message, ``unable to set effective uid to + 0: Operation not permitted``, which has now been silenced. + :gl:`#1042` :gl:`#1090` + +- When ``named-checkconf -z`` was run, it would sometimes incorrectly set + its exit code. It reflected only the status of the last view found; + any errors found for other configured views were not reported. Thanks + to Graham Clinch. :gl:`#1807` + +- When built without LMDB support, ``named`` failed to restart after a + zone with a double quote (") in its name was added with + ``rndc addzone``. Thanks to Alberto Fernández. :gl:`#1695` |
