This update for nsd fixes the following issues :
nsd was updated to the new upstream release 4.3.4
FEATURES :
BUG FIXES :
Fix that symlink does not interfere with chown of pidfile (boo#1179191, CVE-2020-28935)
Fix #128: Fix that the invalid port number is logged for sendmmsg failed: Invalid argument.

New upstream release 4.3.3 :
FEATURES :
Follow DNS flag day 2020 advice and set default EDNS message size to 1232.
Merged PR #113 with fixes. Instead of listing an IP-address to listen on, an interface name can be specified in nsd.conf, with ip-address: eth0. The IP-addresses for that interface are then used.
New upstream release 4.3.2
FEATURES :
Fix #96: log-only-syslog: yes sets to only use syslog, fixes that the default configuration and systemd results in duplicate log messages.
Fix #107: nsd -v shows configure line, openssl version and libevent version.

BUG FIXES :
Fix to omit the listen-on lines from log at startup, unless verbose.
Fix #97: EDNS unknown version: query not in response.
Fix #99: Fix copying of socket properties with reuseport enabled.
Document default value for tcp-timeout.
Merge PR#102 from and0x000: add missing default in documentation for drop-updates.
Fix unlink of pidfile warning if not possible due to permissions, nsd can display the message at high verbosity levels.
Removed contrib/nsd.service, example is too complicated and not useful.
Merge #108 from Nomis: Make the max-retry-time description clearer.
Retry when udp send buffer is full to wait until buffer space is available.
Remove errno reset behaviour from sendmmsg and recvmmsg replacement functions.
Fix unit test for different nsd-control-setup -h exit code.

New upstream release 4.3.1
BUG FIXES :
New upstream release 4.3.0
FEATURES :
Fix to use getrandom() for randomness, if available.

Add feature to drop queries with opcode UPDATE.
BUG FIXES :
Fix whitespace in nsd.conf.sample.in, patch from Paul Wouters.
use-systemd is ignored in nsd.conf, when NSD is compiled with libsystemd it always signals readiness, if possible.
Note that use-systemd is not necessary and ignored in man page.
Fix responses for IXFR so that the authority section is not echoed in the response.
Fix that the retry wait does not exceed one day for zone transfers.
Update keyring as per https://nlnetlabs.nl/people/
New upstream release 4.2.3 :
confine-to-zone configures NSD to not return out-of-zone additional information.
pidfile ‘’ allows to run NSD without a pidfile

fix excessive logging of ixfr failures, it stops the log when fallback to axfr is possible. log is enabled at high verbosity.
The nsd.conf includes are sorted ascending, for include statements with a ‘*’ from glob.
Fix log address and failure reason with tls handshake errors, squelches (the same as unbound) some unless high verbosity is used.
Number of different UDP handlers has been reduced to one. recvmmsg and sendmmsg implementations are now used on all platforms.
Socket options are now set in designated functions for easy reuse.
Socket setup has been simplified for easy reuse.
Configuration parser is now aware of the context in which an option was specified.
document that remote-control is a top-level nsd.conf attribute.

New upstream release 4.2.2 :
Fix #20: CVE-2019-13207 Stack-based Buffer Overflow in the dname_concatenate() function. Reported by Frederic Cambus. It causes the zone parser to crash on a malformed zone file, with assertions enabled, an assertion catches it.
Fix #19: Out-of-bounds read caused by improper validation of array index. Reported by Frederic Cambus.
The zone parser fails on type SIG because of mismatched definition with RRSIG.
PR #23: Fix typo in nsd.conf man-page.
Fix that NSD warns for wrong length of the hash in SSHFP records.
Fix #25: NSD doesn’t refresh zones after extended downtime, it refreshes the old zones.
Set no renegotiation on the SSL context to stop client session renegotiation.
Fix #29: SSHFP check NULL pointer dereference.
Fix #30: SSHFP check failure due to missing domain name.

New upstream release 4.2.1 :
FEATURES :
Added num.tls and num.tls6 stat counters.
PR #12: send-buffer-size, receive-buffer-size, tcp-reject-overflow options for nsd.conf, from Jeroen Koekkoek.
Fix #14, tcp connections have 1/10 to be active and have to work every second, and then they get time to complete during a reload, this is a process that lingers with the old version during a version update.
BUG FIXES :
Fix #13: Stray dot at the end of some log entries, removes dot after updated serial number in log entry.
Fix TLS cipher selection, the previous was redundant, prefers CHACHA20-POLY1305 over AESGCM and was not as readable as it could be.
Fix #15: crash in SSL library, initialize variables for TCP access when TLS is configured.
Fix tls handshake event callback function mistake, reported by Mykhailo Danylenko.
Fix output of nsd-checkconf -h.
New upstream release 4.2.0 :
Implement TCP fast open
Added DNS over TLS

New option hide-identity can be used in nsd.conf to stop NSD from responding with the hostname for probe queries that elicit the chaos class response, this is conform RFC4892
Disable TLS1.0, TLS1.1 and weak ciphers, enable CIPHER_SERVER_PREFERENCE
Update to upstream release 4.1.27 :
FEATURES :
Deny ANY with only one RR in response, by default. Patch from Daisuke Higashi. The deny-any statement in nsd.conf sets ANY queries over UDP to be further moved to TCP as well. Also no additional section processig for type ANY, reducing the response size.

BUG FIXES :
Fix #4194: Zone file parser derailed by non-FQDN names in RHS of DNSSEC RRs.
Fix #4202: nsd-control delzone incorrect exit code on error.
Fix to not set GLOB_NOSORT so the nsd.conf include:
files are sorted and in a predictable order.
Fix #3433: document that reconfig does not change per-zone stats.
Update to upstream release 4.1.25 :
FEATURES :
nsd-control prints neater errors for file failures.
BUG FIXES :
Fix that nsec3 precompile deletion happens before the RRs of the zone are deleted.

Fix nsd-checkconf fail on bad zone name.
Annotate exit functions with noreturn.
Remove unused if clause during server service startup.

Update to upstream release 4.1.24 :
Features
#4102: control interface via local socket
configure --enable-systemd (needs pkg-config and libsystemd) can be used to then use-systemd: yes in nsd.conf and have readiness signalling with systemd.
RFC8162 support, for record type SMIMEA.
Bug Fixes
Patch to fix openwrt for mac os build darwin detection in configure.
Fix that first control-interface determines if TLS is used. Warn when IP address interfaces are used without TLS.
#4106: Fix that stats printed from nsd-control are recast from unsigned long to unsigned (remote.c).
Fix that type CAA (and URI) in the zone file can contain dots when not in quotes.
#4133: Fix that when IXFR contains a zone with broken NSEC3PARAM chain, NSD leniently attempts to find a working NSEC3PARAM.
