Hi,

NSD 4.3.2rc1 pre-release is available:
https://nlnetlabs.nl/downloads/nsd/nsd-4.3.2rc1.tar.gz
sha256 c99bf7c14b70d92dec53a2e13cbc0f210061e4099471cfdfa54c71c8e0f9fd77
pgp https://nlnetlabs.nl/downloads/nsd/nsd-4.3.2rc1.tar.gz.asc

This is the maintainer's pre-release.

This release has bug fixes and some new options. The new commandline
option for nsd '-v' shows the configure line and library versions. The
log-only-syslog option stops duplicate log messages with systemd if
enabled. And the min-expire-time option stops zones from having an
expire time that is too low, forcing too much effort by zone fetching.

4.3.2

Hello Wouter,

I compiled the new version and noted not one single warning.

But there is no change regarding my current issue.
I reviewed the list archive. The current symtoms (segfault after AXFR) look /very/ similar to a solved issue last year:

just build an run with minimal configuration:

$ ./configure && make

# cat /tmp/nsd.conf
server:
  ip-address: 127.0.0.1@5353
  xfrdir: /tmp/
  xfrdfile: "/tmp/xfrd.state"
  database: ""

I think, on STRG+C no error should happen. Maybe there is any relation to "warning: process terminated with status 11"

Hi Andreas,

You may want to set (export) CFLAGS="-g -O0" before running configure
and then start NSD through valgrind (valgrind nsd ...). The output will
(hopefully) show where NSD accesses already freed or uninitialized
memory as status 11 indicates a segmentation fault.

Cheers,
Jeroen

Hi,

NSD 4.3.2 release is available:

Hello Wouter,

(sorry for reporting an minor issue just after release)

I run ./configure --with-pidfile="" to avoid nsd is dealing with a pidfile.
This was suggested here: https://lists.nlnetlabs.nl/pipermail/nsd-users/2020-May/002868.html

But unfortunately "make install" fail:
...
./install-sh -c -d /usr/local/sbin
./install-sh -c -d /etc/nsd
./install-sh -c -d
install: no input file specified

I guess, it's this: https://github.com/NLnetLabs/nsd/blob/master/Makefile.in#L127

Yes it is. Fixed it in
https://github.com/NLnetLabs/nsd/commit/490bfcb0fd8d7b47e781b633dafee1d83e93cb3a

Thanks for the report.

Best regards, Wouter
