hello. please forgive me if the question were asked before. after some research on netfilter there are few loose ends that i cant comprehend.
- where is the memory of the queue is and how is it being handled?
- when you are using the queue is it being copied to the userspace or that you map the memory and how it influences the system performance.
I would appreciate it if you could answer these questions but directing me to a good reference would be fine too.
