Yes, Yes, Yes, and Yes. I'm making the assumption that the common case will be with a veth device in the container and that all of the aforementioned attributes should be copied over. In the future case where we could potentially have a real device in the container, it probably doesn't make sense to copy the mac address.

I'm sure it's possible, but no, I haven't planned out everything for the next year. If you have strong feelings about what should be done in user and kernel space, feel free to share :) DL> Argh ! I was hoping there was something else than the source code The header file makes it pretty clear what is going on, but maybe the Documentation/checkpoint/readme.txt will help. Putting all the details in such a documentation file would be rather silly at the moment, given that new things are being added at a rapid rate and it would duplicate the only description that matters, which is the header file. -- Dan Smith IBM Linux Technology Center email: danms-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
