Hello, I'm trying to understand if Knot can solve our performance problem with big scale dynamic DNS deployment. Currently we use BIND and the performance of Dynamic Updates is insufficient for our requirements. Doing some research I understood that BIND processes updates sequentially and can't really benefit from SMP. I understand how RCU allows parallel reads with updates. But reads is not an issue in our deployment. My question is, does Knot able to process multiple updates in parallel (and not sequentially) and provide a better scale for _updates_? As far as I understand it depends on data structure hierarchy implemented in Knot. -- Alex Massover | Telefónica Digital Architect M +972-54-2279512 alex(a)jajah.com<mailto:alex@jajah.com>

Knot DNS 1.4.6 patch release

by Jan Kadlec

Hello List! Today, we release Knot DNS 1.4.6 with two minor fixes. First issue we've fixed would only occur when doing DNSSEC key rollover using the key metadata (via the dnssec-settime tool, for example) - there was a possibility that the server would try to sign the zone continuously for a limited amount of time. DNSSEC data would stay valid all the time though. The other fix concerns mainly RRL users with recvmmsg enabled - when using SLIP other than 1, responses that should have been dropped were actually sent as empty UDP datagrams. Such responses would not be helpful to the attacker, as they are actually smaller than the queries, but they could confuse legitimate clients. This applies for the responses to malformed query messages as well, even if the RRL is disabled. All in all, if you do not use the automatic DNSSEC or RRL, there's probably no need to update. Hopefully, this is the last release before the 1.5RC1 comes out, so stay tuned.
