Netfilter Architecture

Hi,

Was reading your writeup about the netfilter architecture

http://www.netfilter.org/documentation/HOWTO//netfilter-hacking-HOWTO.html

 

I was not able to figure out whether all this functionality is done in the context of a single ISR for each IP Packet or is the traffic cached and opperated on in the back ground?

 

Wondering if you could provide me links and potential issues/ performance guidlines if you are operating in the context of an ISR.

 

thanks,
