Good morning,

thanks for the patch.

Did you try reverting this one and test if things like
"pakfirehub01.i.ipfire.org" resolve again? I have seen that there is some
changes for qname minimisation.

I just tested after adding "qname-minimisation: yes" and
"harden-below-nxdomain: yes" to '/etc/unbound/unbound.conf', but neither
"pakfirehub01.i.ipfire.org" nor its ip-address "172.28.1.165" answered.

No connection through browser, ping loss on both = 100%.

With or without, I get the following answer with 'dig':

...

Hi,

that server is not available from the internet. But that you get that IP address
is enough for me. That didn't happen before.

I will revert that commit and we will see in the testing if this raises any
problems again...

Best,

Hi,

unbound 1.6.0 - with reverted commit - is running here since a few hours
without seen problems so far - we'll see.

One question, being curious:

Could it make sense to compile 'unbound' using '--with-pthreads' for
threading support?

I got the following in '_build.ipfire.log' right now:

...
checking for the pthreads library -lpthreads... no
checking whether pthreads work without any flags... no
checking whether pthreads work with -Kthread... no
checking whether pthreads work with -kthread... no
checking for the pthreads library -llthread... no
checking whether pthreads work with -pthread... yes
checking for joinable pthread attribute... PTHREAD_CREATE_JOINABLE
checking if more special flags are required for pthreads... no
checking for PTHREAD_PRIO_INHERIT... yes
checking for pthread_spinlock_t... yes
checking for pthread_rwlock_t... yes
checking if -pthread unused during linking... no
...

In this regard, I read
https://www.unbound.net/documentation/howto_optimise.html, but I'm not
so skilled in programming to judge whether this would lead to any
advantages...

Best,
Matthias

What else is it using for threading right now?

Hi,

As far as I can see, it uses one thread per processor as set through the
init-file.

Here, the generated 'tuning.conf' contains "num-threads: 2", which is
ok, the machine has two cores.

The question is, what differences would compiling with '--with-pthreads'
make? This option came to my view, but I don't know if this would make
anything better.

Best,
Matthias

We always set that to the number of active processors, yes.

Try it out them. The number of threads will be the same but it should definitely
use pthreads then which is the fastest implmentation of threads in Linux. There
is a few things outside glibc, but I cannot imagine that unbound is using
anything else but pthreads already.

Hi,

it made absolutely NO difference. Binarys were identical, too.

'configure' contains:

...
# Check whether --with-pthreads was given.
if test "${with_pthreads+set}" = set; then :
  withval=$with_pthreads;
else
   withval="yes"
fi
...

Can it be that its enabled automatically, if no option is given!? *sigh*

Best,
Matthias
