Run-time effects of new SIMD code
Hi Anand, Stuart, That is indeed correct. At runtime the CPUID instruction is used to detect which extensions are offered and it chooses based on that. When compiling on x86_64 with SSE4.2 and AVX2 enabled, the binary will actually contain 3 parsers, the most optimal one is used at runtime. Optimized versions can be disabled with --disable-westmere (SSE4.2) and --disable-haswell (AVX2) if

Run-time effects of new SIMD code
Hi Anand, Doing it with "nsd -v" is not implemented right now because it's meant to be transparent to users of the library, but I think you're right and it'd be good to show the info. The kernel is selected when the parse function is called. For NSD it makes sense to select one on startup and always use that one. There's a GH issue for that:

Thanks for the update Jeroen, and for creating the issues to track the suggestions. You didn't answer the parts of my email relating to what happens at compile time, and how the resulting NSD binary is affected depending on what architecture it's compiled on. If you could expand on those, I'd appreciate it. Regards, Anand -------------- next part -------------- An HTML attachment was

query: bad tsig signature for key
hi, At least with a recent version if it is a time sync issue nsd will do a specific log msg that. Laura, can you send over the actual configuration? (maybe replacing the key with a placeholder or rotating the keys afterwards) It sounds strange if nsd checks tsig on the notify, but allow xfr without it.

NSD 4.10.0 compile failure in Homebrew
Hi NSD developers, I submitted a merge request in Homebrew to update NSD to 4.10.0. The compile failed, and I don't know what the error means and how to fix it. Could one of you please take a look? https://github.com/Homebrew/homebrew-core/pull/175796 Regards, Anand

Question about "server-count" config option
Hi there, I have a question about the "server-count" option. nsd.conf(5) simply states that it tells NSD to "start this many NSD servers", with no further commentary. Is there a situation where this value would ever be anything other than 1? Should it equal the number of available CPU cores? Cheers, -- Gavin Brown Chief Technology Officer CentralNic Ltd Innovative,

Question on slave
Hi Jean-Christophe, Anand's answer is entirely correct. Once 4.8.0 is released, zone files will be written once per hour by default.

Question about "store-ixfr"
Hi NSD developers, I have been experimenting with the "store-ixfr" feature in NSD. I have a configuration with: server: zonefiles-write: 0 pattern: store-ixfr: yes With this configuration, NSD transfers zones from a primary, and keeps them in RAM. When the zones are updated, it receives and stores the IXFR in RAM too. I can query NSD with the IXFR qtype, and it replies with

support for ALIAS records
While SVCB/HTTPS provides a better solution for the browsing use case, I see other use cases where ALIAS/ANAME would be ideal, notably in apex RRs. So while fostering SVCB/HTTPS deployment is a good thing, I wouldn?t mind name server software implementing ALIAS. Including NSD, but I reckon it?s much more challenging to do due to NSD architecture than it was to implement it in PowerDNS. But if

SIGSEGV in rbtree_find_less_equal
Hi Chris, I've properly started looking into this yesterday. NSD definitely shouldn't crash, still working on that. However, the provided zone is invalid too(?) I'm not the foremost expert on NSEC3 (or even DNSSEC), but is seems an NSEC3 is missing for bar.foo.com. Empty non-terminals should still have an NSEC3 RR. (Of course, the delegation point should be at bar.foo.com. too and

nsd issue
Hi Jean Claude, The message is printed when the bind operation failed. Why that happens is hard to say, I'd need more information for that. As the message does not say: address already in use (or similar), I'm guessing the address is not configured?
