NSD 4.10.0

Download:: nsd-4.10.0.tar.gz | sha1 | sha256 | pgp sig
Date:: 13 June, 2024

Features

Merge #278: Replace Flex+Bison based zone parser with simdzone. Performance of loading zones and IXFRs is greatly improved by using the simdzone project by NLnet Labs. The optimized presentation format parser leverages SIMD instructions in modern CPUs to improve throughput. Right now SSE4.2 and AVX2 instruction sets are supported, other instruction sets will use the fallback implementation, which still is a decent improvement over the Flex+Bison based parser.

Bug Fixes

Fix that when the server truncates the pidfile, it does not follow symbolic links.

NSD 4.9.0

Download:: nsd-4.9.0.tar.gz | sha1 | sha256 | pgp sig
Date:: 3 April, 2024

Features

Merge #315: Allow SOA apex queries to otherwise with allow-query protected zones for clients matching a provide-xfr rule, because clients that are allowed to transfer the zone need to be able to query SOA at the apex preceding the actual transfer.
Merge #304: Support for Catalog zones version "2" as specified in RFC 9432. Both the consumer as well as the producer role are implemented, but only a single catalog consumer zone is allowed. The "coo" property, only relevant with multiple catalog consumer, is therefore not supported. The "group" property is supported. Have a look at the nsd.conf man page for details on how to configure and use catalog zones.

Bug Fixes

Fix #313: nsd 4.8 stats with implausible spikes.
Fix compile with memclean for xfrd nsd.db close.
In xfrd del secondary zone, the timer could perhaps have event_added, and if so, it would not be event_del if a tcp connection is active at the time. This could cause the libevent event lists to fail. Also fix to make sure to set event_added for the nsd-control ssl nonblocking handshake and check event_added there too, for extra certainty.
Merge #316: Fix to reap defunct children by the reload process that emerged when some serve child processes were still serving TCP request while the others had already quit, while the reload process was waiting for the signal from the backup/old main process that all children exited.
Fix (also from Merge #316) to reap exited children more frequently from server main loop for processes that exited during reload, but missed the initial reaping at start of the main loop because they took somewhat longer to exit.

NSD 4.5.0

Download:: nsd-4.5.0.tar.gz | sha1 | sha256 | pgp sig
Date:: 13 May, 2022

Features

Merge PR #209: IXFR out This adds IXFR out functionality to NSD. NSD can copy IXFRs from upstream to downstream clients, or create IXFRs from zonefiles. The options store-ixfr: yes and create-ixfr: yes can be used to turn this on. Default is turned off. The options ixfr-number and ixfr-size can be used to tune the number of IXFR transfers and total data size stored. This is configured per zone, the IXFRs are served to the hosts that are allowed to perform zone transfers. And if TSIG is configured, signed with the same key. The content is stored to file if a zonefile is configured for the zone, in the zonefile.ixfr and zonefile.ixfr.2, .. files. They contain readable text format. The number of IXFRs is num.rixfr in statistics output, also per zone if per zone statistics are enabled. If offline, nsd-checkzone -i can create ixfr files. NSD already supports requesting IXFRs, this addition allows NSD to serve IXFR transfers to clients. NSD stops responding with NOTIMPL to IXFR requests, also for zones that do not have IXFR enabled. The clients gets a full zone reply or a status reply if the serial is up to date.

Bug Fixes

NSD 3.2.11

Download:: nsd-3.2.11.tar.gz | sha1
Date:: 09 Jul, 2012

Features

Fallback to AXFR if IXFR is unknown at the primary. NSD considers IXFR unknown at the primary if there is a negative response for the IXFR RRtype. This does not override the value for 'allow-axfr-fallback'.
Allow for reading in new DNSKEY algorithm mnemonics (RFC5155, RFC5702, RFC5933, and RFC6605 (ECDSA)).
Zone statistics, enable with --enable-zone-stats. This stores the BIND8 stats per zone in a configurable statistics file. This option does not scale and should therefore not be enabled when serving many zones.
Support for TLSA RRtype (DANE).

Bug Fixes

Fix for qtype ANY for a wildcard domain in NSEC signed zone: Don't add the wildcard domain NSEC into the answer section. Instead, put the wildcard expanded NSEC into the answer section and keep the wildcard domain NSEC in the authority section.

NSD 3.2.9

Download:: nsd-3.2.9.tar.gz | sha1
Date:: 23 Nov, 2011

Features

Minimize responses to reduce truncation: NSD will only add optional records to the authority and additional sections when the response size does not exceed the minimal response size. _p()The minimal response size is 512 (no-EDNS), 1480 (EDNS/IPv4), 1220 (EDNS/IPv6), or the advertized EDNS buffer size if that is smaller than the EDNS default. _p()The feature is enabled by default. You can disable it by configuring NSD with --disable-minimal-responses. _p()
Less NSEC3 prehashing. This will make NSD handle zone transfers faster, but will decrease the performance of NXDOMAIN and wildcard NODATA responses. Full prehashing is enabled by default. If you want less NSEC3 prehashing, configure NSD with --disable-full-prehash. Thanks Secure64 for the patch.

Small speedup where xfrd could briefly be busy-waiting.
If master sends IXFR with glue that is already present in the zone this is silently accepted. Printed in debug mode -L 2. To make the log file smaller.
Exponential backoff for zones that never worked to max of 4 hours. For expired zones the SOA retry values are used.
allow-notify acl entries 'NOKEY' match only queries without TSIG.
Answers to valid notifies contained wrong RR counts in the header. The notifies were processed correctly, but now the acknowledgement reply is in correct DNS format.

NSD 2.2.0

Download:: nsd-2.2.0.tar.gz | md5
Date:: 18 Jan, 2005

Features

nsd-xfer: replacement program for named-xfer to perform zone transfers using AXFR. TSIG is supported by nsd-xfer but not yet by the nsd server. DNSSEC is also supported. TSIG requires OpenSSL version 0.9.7 or higher, configure using --disable-tsig if you do not have OpenSSL installed. Configure using --with-ssl=path if OpenSSL is not installed at a standard location.

Bug Fixes

Fixed endian problem in WKS record.
Protocol can now be specified numerically in WKS record.
Allow escape sequences (\DDD) in TTL, RR class, and RR type.
The zone compiler now accepts many more characters in unquoted strings such as domain name labels. The characters no longer need to be escaped with a backslash.
Close included files after reading.
Maximum TCP message size is now 65535 bytes. AXFR response packets are still limited to 16383 bytes for optimal compression of dnames.
The TSIG key for AXFRs can now also be stored in the file <zonename>.tsiginfo. This makes it possible to use TSIG with multiple master servers.
Signals are no longer blocked while performing I/O so the server should respond quicker to signals.
Fixed parsing of LOC rdata. Fractions and altitude were not handled correctly.
