Hi all,I just started working on packaging fwknop 2.6.9 from scratch when I found this bug. I have spoken to infinity0 today, who would be happy to sponsor the upload as well.
As I only just started reading the Debian maintainers guide I tend to trust your work more than mine, too. I can try and have a look to see if I can identify what's going wrong with hardening flags though.
