NSD 4.13.0
This release enables some commonly used features by default, and
introduces experimental support for AF_XDP sockets that can be
enabled with the --enable-xdp feature flag (see
https://nsd.docs.nlnetlabs.nl/en/latest/xdp.html).
4.13.0
FEATURES:
Use '(all)' and '(none)' for the socket server affinity
log output instead of '*' and '-'.
The --enable-bind8-stats feature, was already enabled by default,
is described as enabled by default in usage.
The --enable-zone-stats feature is enabled by default. It can be
turned on with config like zonestats: "%s".
The --enable-ratelimit feature is enabled by default. The
ratelimit value is off by default. It can be turned on with
config like rrl-ratelimit: 200.
The --enable-dnstap feature is enabled by default. If fstrm-devel
or protobuf-c are not found by configure it prints an error.
It can be turned on with config like dnstap-enable: yes.
Change default for send-buffer-size to 4m, to mitigate a
cross-layer issue where the UDP socket send buffers are
exhausted waiting for ARP/NDP resolution. Thanks to Reflyable
for the report.
Disable TLSv1.2 if TLSv1.3 is available.
Merge #449: Add useful logging for XoT transfers.

NSD_4_11_1_REL: NSD 4.11.1
NSD version 4.11.0 had a serious bug in which applying updates to
zones (and other modifications that require a reload, such as adding
and deleting zones), could stop entirely after reception of a broken
or corrupted update via zone transfer. We believe that this broken
state would appear as one of the NSD processes consuming 100% CPU.
Version 4.11.1 has this corrected as well as some other smaller
non-critical bugs.
We strongly advise to not run NSD version 4.11.0, and if you have
it deployed already, upgrade to 4.11.1 at the earliest possible
opportunity.
Many thanks to the people at SUNET and netnod (Fredrik and Arvid
and all the others) that helped us to get to the bottom of this
critical issue!
nsd 4.11.1
BUG FIXES:
Fix #415: Fix out of tree builds. Thanks Florian Obser (@fobser).
Fix #414: XoT interoperability with BIND and Knot
Fix #421: old-main can quit before the reload process received
from old-main that it is done on the reload_listener pipe.
Thanks Otto Retter.
Fix whitespace in comment.
Fix #424: Stalled updates after corrupt transfer.
simdzone 0.2.1
BUG FIXES:
Cleanup westmere and haswell object files (#244) Thanks @fobser
Out of tree builds (#415)
Fix function declarations for fallback detection routine in
isadetection.h.

NSD 4.11.0
This release has various small features and bugfixes.
One notable feature is that configuration can be reloaded and
evaluated on SIGHUP, when enabled with the new "reload-config"
option. Also new is that cookie secrets will be reevaluated from
config too.
One notable bugfix is to process and apply non transfer tasks before
transfer tasks during reloads. Before, non transfer tasks (such as
adding or deleting zones) would be lost when batched together with
a transfer task that would fail to apply.
NSD 4.11.0
FEATURES:
Support reloading configuration on SIGHUP.
Fix #383: log timestamps in ISO8601 format with timezone.
This adds the option log-time-iso: yes that logs in ISO8601
format.
Updated cookie secrets management.
The default cookie secret file location can be set at compile time
with the --with-cookiesecretsfile=path option to configure. The
default location is changed to {dbdir}/cookiesecrets.txt. The
previous default location will be checked at startup when there is
no cookie secrets file at the new default location.
A staging cookie can now also be configured in the configuration
file and secrets configured in the configuration file now take
precedence over those read from file.
All DNS related setting in the configuration file will be reevaluated
and effectuated after nsd-control reconfig.
Merge #398: RFC 9660 The DNS Zone Version (ZONEVERSION) Option
Merge #406: ohttp and tls-supported-groups SvcParam suppor
Merge #408: NINFO, RKEY, RESINFO, WALLET, CLA and TA RR types
Merge #409: Writing of NSAP-PTR, GPOS and HIP RR types
Merge #407: Better balanced verbosity levels for logging.
BUG FIXES:
Fix title underline and declaration after statement warnings.
Add cross platform freebsd, openbsd and netbsd to github ci.
Update simdzone to include fix for netbsd double bswap declarations,
and also semantic checks for DS and ZONEMD. And CFLAGS has -march
prepended to fix detection.
Merge #376: Point the user towards tcpdump for logging individual
queries.
Track $INCLUDEs in zone files.
Fix ci to update macos-12 to the macos-15 runner image.
Merge #390: Apply non-xfr tasks before xfr tasks.
This fixes an issue where non-xfr tasks are lost when they are
batch processed together with non-xfr tasks.
This merge also changes that notifies are passed on from the serve
processes to the xfrd directly instead of via main. This was
necessary to allow applying the non-xfr tasks without forking a
backup-main for the sole purpose of forwarding notifies.
Merge #391: Update copyright lines (in version output).
Fix #392: Inconsistent documentation about control-interface.
Merge #395: Explain the zonefile example better.
Merge #394: Fix the path to use doc/manual/.
Fix analyzer issue in do_print_cookie_secrets to check for failure.
Merge #404: Introducing Sphinx substitution in code blocks.
As well as other fixes with Sphinx build.
Update Copyright lines in help output
Merge #395: Explain zonefile example better
Merge #394: Fix doc path (fixes "Edit on GitHub" button in the docs)
Fix Makefile for parallel build failure around bison rule.
Fix #405: Fix typo in documentation.
Treat a mismatch in RRset TTLs as a warning.
simdzone 0.2.0
FEATURES:
Add semantic checks for DS and ZONEMD digests (#205).
Support registering a callback for $INCLUDE entries
(#229).
Add tls-supported-groups SvcParam support.
Check iana registries for unimplemented (new) RR types and
SvcParamKeys.
Add support for NINFO, RKEY, RESINFO, WALLET, CLA and TA RR types.
BUG FIXES:
Prepend -march to CFLAGS to fix architecture detection
(#372).
Fix propagation of implicit TTLs (#375).
Fix detection of Westmere architecture by checking for CLMUL too.
Fix compilation on NetBSD (#233).
Fix reading specialized symbolic links (#380).

NSD 4.10.1rc1
This release consists primarily of bug fixes.
@bilias implemented mutual TLS authentication for zone transfers. Please
consult the nsd.conf manual for details on the newly introduced configuration
options tls-auth-port and tls-auth-xfr-only.
@orlitzky provided integration for the OpenRC init system.
Version 4.10.0 was the first release to integrate simdzone. Build issues on
OpenBSD releases before 5.6, Gentoo and Solaris have been reported and fixed.
The fallback parser, used on systems that lack SSE4.2 and AVX2 instruction
sets, contained some bugs with regards to state keeping and under certain
circumstances a use after free bug was encountered in buffer management.
4.10.1
FEATURES:
Merge #352 from orlitzky: contrib: add OpenRC service script, config
file, and tmpfiles entry.
Merge #337 from bilias: Mutual TLS-AUTH.

NSD 4.10.0
Jun 13, 2024
@wcawijngaards wcawijngaards
NSD_4_10_0_REL

NSD 4.10.0
NSD 4.10.0
Version 4.10.0 integrates simdzone and drops the Flex+Bison zone
parser.
NSD used a Flex+Bison based zone parser since version 1.4.0. The parser
served NSD well, but zones have increased in size and zone loading
performance has been problematic for some users.
With the integration of simdzone
(https://github.com/NLnetLabs/simdzone),
performance of loading zones and IXFRs is drastically improved. Quick
measurements show improvements ranging anywhere from 3.8x to 1.6x,
depending on zone size and database type, though the improvements will
be less noticable for NSEC3 zones due to pre-hashing.
simdzone 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.
The release has additional fixes from the release candidate. The
parse of lowercase type names is fixed and the x86_64 variable is
set to no for other machines.
4.10.0
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.
Fix #317: nsd should not chown its PID file.
For #317: Modify nsd service script to stop NSD from creating a pid
file that systemd is not using.
Fix #324: Clarify the purpose of contrib/bug390.patch.
Fix IXFR requests upstream for zones with a long name. Thanks for the
report to Yuuki Wakisaka from Internet Initiative Japan Inc.
Unit test for dname subdomain test used by xfrd-tcp.c.
Fix #329: TCP accept queues number.
Fix that the reload handler for sigchild uses signal_add, and also
that the signal handler is restored when done.
Fix that when server verify is done it resets the sigchild handler.
Fix makedist.sh for simdzone inclusion.
Fix makedist.sh to remove simdzone git tracking information and
scripting temporaries from tarball.
Fix error output of makedist.sh.
Use simdzone version with name parser fix.
Bump simdzone version to fix OpenBSD build issues.
Bump simdzone to include minor fixes.

over the Flex+Bison based parser.
The release candidate window will be longer this time as simdzone is rather
new and while it has been tested on various architectures and operating
systems, it is likely problems will pop-up due to sheer amount of code. Please
consider giving this release candidate a good run and report any problems.

NSD 4.9.1
NSD 4.9.1
This release fixes the builds scripts in the release of version 4.9.0.
Version 4.9.0 adds support for DNS Catalog Zones (RFC 9432) version "2".
Both producer and consumer roles for catalog zones are implemented, but
only a single consumer zone is allowed. The "coo" property, relevant
when multiple consumer zones can be configured, is therefore not
supported. The "group" property is. Consult the nsd.conf man page for
details on how to configure and use catalog zones.
Thanks to Fredrik Pettai from Sunet for providing feedback and testing
DNS Catalog Zones.
4.9.1
BUG FIXES:
Use rooted temporary path in makedist.sh.

Thanks to Fredrik Pettai from Sunet for providing feedback and testing
DNS Catalog Zones.
4.9.0
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 to sync the tests script file common.sh.
Update test script file common.sh.
Fix #306: Missing AC_SUBST(dbdir) breaks installation with 4.8.0.
Fix for #306: Create directory for xfrd.state and zone.list files
in make install.
Merge #307 from anandb-ripencc: Many improvements to the nsd.conf
man page.
Fix #308: Deprecate "multi-master-check" in favour of
"multi-primary-check".
Merge #309: More RFC 8499 compliance.
Fix control-reconfig-xfrd test for zonestatus primary that is
printed by nsd-control zonestatus.
Move acx_nlnetlabs.m4 to version 47, with crypt32 check.
Move acx_nlnetlabs.m4 to version 48, with ssp and getaddrinfo
include check.
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.
Fix timing sensitivity in ixfr_outsync test.
Test if debug is available in do-tests.
Enforce timeout from NSD in ixfr_gone test.
Update expressions in ixfr_and_restart test.
Make algorithm explicit in control-repattern test.
Switch algorithm to hmac-256 for testplan_mess test.
Replace multiple strcat and strcpy by snprintf.
