Hi folks, A question on how to get the current network namespace. I am porting a driver from 2.6.18 to 2.6.28. We do protocol analysis by the 5 tuples: src IP, dst IP, src port, dst port and transportation protocol. We have code in usr space to pass in these parameters, then kernel space code do search through udp_hash and tcp_hash to locate the exact socks. Since 2.6.18 doesn't support network namespace, this works fine. But as 2.6.28 supports network namespace, search through udp_hash and tcp_hash requires a sixth parameter -- network namespace as well. So the question is, how to get current network namespace in this case? Is it available from user space code and passed to kernel code, or there is function to get it in kernel space? It seems I could go by by using the system init_net, but I want to be new feature friendly at least. Would appreciate your valuable inputs.
