Hi, after working on this bug for a while, I was able to distill a
minimum code that triggers the segfault. The callback routine invoked
from pcap_loop needs to set a signal handler that it's used during the
callback.
In the fwknopd code, this happens when calling iptab
Faster than what I've expected, I've found what caused the segfault:
Pcap.xs is allowing unsafe signals during the callback. I don't know
why upstream did this, but this has to be discussed with them and
filled as a bug in CPAN.
With the attached patch, my original testcase no longer segfaults.

Meanwhile this is solved, see the attached patch that's useful as a

In the fwknopd code, this happens when calling iptables, which triggers
