I love your UDP packet flow tool, kudos for making that! I've always wondered how packets move through an OS. Also interesting how many gotos I see all over the place, even though everyone says "goto is the devil". Then again maybe this code was written long before that "proverb" came into existence.

Since you mentioned you love that, I will mention this netfilter packet flowchart by Jan Engelhardt [1]

Thanks! I suggest to have a look at a 'live' debugger session video here: https://github.com/dmkskd/linux-kernel-debugging-on-mac?tab=... given your interest

if you have an ARM64 mac (sorry for only supporting this OS at the moment) it should be easy to set this up on your end
