Changelog:
This release adds the zone verification support from the CreDNS code.
There are also some bug fixes in the ixfr out code.
Zone verification can start a verifier program that reads the new zone
data. It can reject the update. Or process the new zone data. The intent
is for a DNSSEC verifier to inspect the zone before it is passed on with
zone transfer or served to clients.
The zone verification can be enabled with enable: yes in the verify
section in nsd.conf. You can then list the interfaces the NSD listens on
while the verifier is active, so it can send queries for the new zone
contents. With verify-zones: yes zones are verified by default. The
command that is executed can be set with the verifier: ldns-verify-zone
option. With verifier-count the max number of concurrent verifiers can
be set. With the verifier-feed-zone: yes option the zone can be input
on stdin to the verifier program. A timeout to stop the verifier can be
set with the verifier-timeout option.
Per zone options can also be set for a pattern or for a zone, for zone
verification. With verify-zone the zone verification can be enabled
per zone. The verifier can be set per zone. And the verifier-feed-zone
and verifier-timeout options can be controlled per zone.
FEATURES:
Port zone-verification from CreDNS to NSD4.
BUG FIXES:
Fix static analyzer reports on ixfrcreate temp file.
Fixup wrong ixfrcreate fread return check.

Changelog:
6 May 2022: Wouter
- Merge #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.

nsd-control print_tsig, update_tsig, add_tsig, assoc_tsig
and del_tsig. These changes are gone after reload, edit the
config file (or a file included from it) to make changes that
last after restart.

- Fix #590: rrl log does not print wildcard as a star but escaped.
- Fix #591: rrl log messages at verbosity level 1.
- fix strptime implicit declaration error on OpenBSD.
- Fix -O3 compile flag to -O2 to avoid miscompilations.
- Allow user to override the -g -O2 CFLAGS in ./configure.
- Fix endian.h include for OpenBSD.
- Fix #600: document that provide-xfr provides AXFR and not IXFR.
- Fix rising-load-average or memory-leaks in OSes (Linux since 2.6),

for them. Fix makes it so there is no very deep string of
process parents.
- Remove .LP after .SH in man pages.

Bug Fixes:
- Fix nsd.db unclean close check. Previous databases are considered
unclean by the code and are created anew.
- Adds nsd.db larger than 400Tb check for sanity. Also test if
filesize as documented in the file is correct.
- nsd waits for tasks to complete on stop, prevents nsd.db corruption.
- fix to not delete tmpdir too early in shutdown process.
- disabled udb checking functionality that made it very slow,
this was enabled when enable-checking was turned on.

Bug Fixes:
* Fix expired zones to give SERVFAIL, also when parent zone loaded.
* documented nsd-control zonestatus output in nsd-control manpage.
* remove mention of nsdc from nsd-checkconf manpage.
* Disabled recvmmsg and sendmmsg usage by default because kernel
versions have implementation issues: ipv6 ignored, security issues.
* Detect libevent2 install automatically by configure, and use
event2 header files if necessary.
* Fix #551: change Regent to Copyright holder in the LICENSE,
to match the definition on opensource.org for the BSD License.
* Fix #552: zonefile loads on nsd-control reconfig when the name
of the file has changed.
* Fix leak of zone name after zonefile read and fix malloc too
large that would be leaked in the radix tree.

|
|
Features:
* recognizes ip-address and interface as synonyms for convenience.
* Support for EUI48 and EUI64 RR types enabled by default (RFC 7043).
* Support for CAA RRtype (RFC 6844).
* NSID can be set with "ascii_somestring" in ascii.
Bug fixes:
* Fix xfrd when zone transfer TCP contains zero length packets.
* Fix for NSEC3 zones where parent zone is co-hosted, also NSEC3,
because AXFRs overwrote nsec3 administration in the child zone.
* Fix that bad IXFR updates do not result in double SOA records,
and that an AXFR is started (attempted) when the zone state seems
to be inconsistent with the master's zone state.
* Log ip address for sendto and sendmmsg failures.
* Fix segfaults after read of zones with rr type WKS from zonefile.
* Seed PRNG for openssl at start of daemon, fixes SSL connection issue.

|
|
Features:
* documented in doc/NSD-4-features. Change configuration without restart,
direct nameserver control with nsd-control, support a higher number of zones.
Higher performance (compared to NSD3).
* nsdc is gone. Use kill -HUP for reload (also checks if zonefiles have
changed and rereads them), and kill -TERM for quit. Or use nsd-control
for detailed control.
* cron job for nsdc patch is gone. nsd-control write creates zonefiles.
* nsd.db has a new format that compacts itself when it is changed,
thus nsdc patch is no longer necessary.
* nsd.db is memory mapped, NSD needs (part of) that mmap in ram.
* tcp-count can go above 1000; epoll/kqueue support with libevent.
* nsd-control reconfig for updates with no restart (zones, keys, ..)
* nsd-control-setup to create keys for nsd-control (enable nsd-control
with remote-control: yes in nsd.conf).
|
|
Features:

outgoing-interface is set, or vice versa.
* RRtypes ASFDB, RP, RT should not compress dnames.
* Check that zone directory is within chroot directory.

NSD 3.2.12
Bugfixes
Fix for VU#624931 CVE-2012-2978: NSD denial of service
vulnerability from non-standard DNS packet from any host on
the internet.
NSD 3.2.11
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).
Bugfixes
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.
Fix for accept spinning reported by OpenBSD.
Fix restart failed due to bad ixfr packet because of zone
removed from nsd.conf.
Bugfix #453: typo in nsdc man page.
Operational notes
NSD uses the query name for dname compression again (Fix #235
had as side effect that this didn't happen anymore and is hereby
undone).

Bugfixes:
* Bugfix #421: Truncate pidfile on shutdown, before unlink.
* Bugfix #423: Fix slow zone transfer processing due to
'Fix is_existing flag for ENT' bugfix.
* Bugfix #430: Fix segfault when MAX_INTERFACES set to more than 65K.
* Fix configure.ac strptime check for gcc 4.6.2, acx_nlnetlabs.m4 update
NSD 3.2.9
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.
* 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.
* The feature is enabled by default. You can disable it by configuring NSD
with --disable-minimal-responses.
* 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.
Bugfixes:
* Bugfix #302: nsd accepts XFR but refuses to re-read the slave zone.
* Bugfix #365: set patch style and zonec verbose for nsdc.
* First step of bug #369: RRSIG DNSKEY sets zone to be treated DNSSEC.
* Bugfix #375: typos in nsd.conf.5.
* Bugfix #381: Binary escaped and transfers.
* Bugfix #397: Don't allow relative domain names as origin in $INCLUDE
directives.
* Fix printout of IPSECKEY by nsd-patch.
* Fix is_existing flag for ENT when domain that has a shared ENT is deleted
by IXFR. (ENT == Empty Non-Terminal)
* Fix bug if the zonefile is changed for a secondary but stored transfers
are applied, and stop it from applying ixfr to empty zone. The zone is
flagged with error and AXFR-ed.
* Fix to have no authority NS set processing for CNAMEs.
* Fix nsd-checkconf to check tsig algorithms properly.
* Set the AA bit on responses that have an authoritative CNAME.
* Fix denial of existence response for empty non-terminal that looks like
a NSEC3-only domain (but has data below it).
Operational notes:
nsd.db version number increased because NSD 3.2.7 and earlier zonec is not
compatible due to the TXT strings change. Please run nsdc rebuild before
running NSD 3.2.9 and later versions.

Bugfixes:
* Do setusercontext before chroot, otherwise login.conf etc. are required inside chroot.
* Bugfix #216: Fix leak of compressiontable when the domain table increases in size.
* Bugfix #348: Don't include header/library path if OpenSSL is in /usr.

* Bugfix: nsd-checkconf -o outgoing-interface omits NOKEY.
* Undo Bugfix #235: Don't skip dname compression, messes up packets that do need compression.
Operational notes:
* Use 'make clean' to clean up files that make created.
* Use 'make realclean' to also clean up files that were generated by running ./configure.
* Use 'make devclean' to also clean up autoconf, autoheader files.
NSD 3.2.7:
Bugfixes:
* Bugfix #253: Don't put NS RRs in a response with QTYPE=DS.
* Bugfix #320: use arcrandom(4) for QID generation if available.
* Bugfix #328: nsd-checkconf overrun.
* Bugfix #343: nsdc update fix.
* Bugfix #347: Wrong NSEC3 returned for nodata response QTYPE=DS no delegation.
* Bugfix: Allow for huge amount of strings in TXT (and other) records.
* Bugfix: nsdc can now deal with tsig algorithms other than hmac-md5.
* Fixed several parts in the documentation, including #306, #345.
