This provides a mapping from a + domain name to a cryptographic currency wallet. Multiple mappings can + exist if multiple records exist. :gl:`#4947` :gl:`!9555` + +Feature Changes +~~~~~~~~~~~~~~~ + +- Allow IXFR-to-AXFR fallback on DNS_R_TOOMANYRECORDS. ``1d6465ff169`` + + This change allows fallback from an IXFR failure to AXFR when the + reason is `DNS_R_TOOMANYRECORDS`. This is because this error condition + could be temporary only in an intermediate version of IXFR + transactions and it's possible that the latest version of the zone + doesn't have that condition. In such a case, the secondary would never + be able to update the zone (even if it could) without this fallback. + + This fallback behavior is particularly useful with the recently + introduced `max-records-per-type` and `max-types-per-name` options: + the primary may not have these limitations and may temporarily + introduce "too many" records, breaking IXFR. If the primary side + subsequently deletes these records, this fallback will help recover + the zone transfer failure automatically; without it, the secondary + side would first need to increase the limit, which requires more + operational overhead and has its own adverse effect. :gl:`#4928` + :gl:`!9472` + +- Remove statslock from dnssec-signzone. ``5c51e044c42`` + + Silence Coverity CID 468757 and 468767 (DATA RACE read not locked) by + converting dnssec-signzone to use atomics for statistics counters + rather than using a lock. :gl:`#4939` :gl:`!9501` + +- Use release memory ordering when incrementing reference counter. + ``b2bbceecfe8`` + + As the relaxed memory ordering doesn't ensure any memory + synchronization, it is possible that the increment will succeed even + in the case when it should not - there is a race between + atomic_fetch_sub(..., acq_rel) and atomic_fetch_add(..., relaxed). + Only the result is consistent, but the previous value for both calls + could be same when both calls are executed at the same time. + :gl:`!9568` + +Bug Fixes +~~~~~~~~~ + +- Fix a statistics channel counter bug when 'forward only' zones are + used. ``5a6c5218ad1`` + + When resolving a zone with a 'forward only' policy, and finding out + that all the forwarders are marked as "bad", the 'ServerQuota' counter + of the statistics channel was incorrectly increased. This has been + fixed. :gl:`#1793` :gl:`!9503` + +- Fix a bug in the static-stub implementation. ``1e5bc23921e`` + + Static-stub addresses and addresses from other sources were being + mixed together, resulting in static-stub queries going to addresses + not specified in the configuration, or alternatively, static-stub + addresses being used instead of the correct server addresses. + :gl:`#4850` :gl:`!9572` + +- Don't allow statistics-channel if libxml2 and libjson-c are + unsupported. ``e8c2c9c9dca`` + + When the libxml2 and libjson-c libraries are not supported, the + statistics channel can't return anything useful, so it is now + disabled. Use of `statistics-channel` in `named.conf` is a fatal + error. :gl:`#4895` :gl:`!9487` + +- Limit the outgoing UDP send queue size. ``6c1fc4ae544`` + + If the operating system UDP queue gets full and the outgoing UDP + sending starts to be delayed, BIND 9 could exhibit memory spikes as it + tries to enqueue all the outgoing UDP messages. Try a bit harder to + deliver the outgoing UDP messages synchronously and if that fails, + drop the outgoing DNS message that would get queued up and then + timeout on the client side. :gl:`#4930` :gl:`!9512` + +- Do not set SO_INCOMING_CPU. ``694cb11a173`` + + We currently set SO_INCOMING_CPU incorrectly, and testing by Ondrej + shows that fixing the issue by setting affinities is worse than + letting the kernel schedule threads without constraints. So we should + not set SO_INCOMING_CPU anymore. :gl:`#4936` :gl:`!9505` + +- Don't enable REUSEADDR on outgoing UDP sockets. ``b902a4e214a`` + + The outgoing UDP sockets enabled `SO_REUSEADDR` that allows sharing of + the UDP sockets, but with one big caveat - the socket that was opened + the last would get all traffic. The dispatch code would ignore the + invalid responses in the dns_dispatch, but this could lead to + unexpected results. :gl:`!9584` + + diff --git a/doc/notes/notes-9.18.31.rst b/doc/notes/notes-9.18.31.rst new file mode 100644 index 0000000000..691a792d90 --- /dev/null +++ b/doc/notes/notes-9.18.31.rst @@ -0,0 +1,78 @@ +..
