Hi,
I'm new in kernel programming..
I'm reading the chapter about namespaces in the "Linux Kernel Networking" (Rami Rosen), but I could not find a way to create a network namespace. I understand that I should use methods like create_nsproxy(), copy_net_ns() and create_new_namespaces(), but I don't know how to set their parameters.
For example, the method copy_net_ns(unsigned long flags, struct user_namespace *user_ns, struct net *old_net), defined in net_namespace.h.
I know that for flags, a may use CLONE_NEWNET, but what about the other parameters, user_ns and old_net?
