we had a phone discussion with Antonio, Marek, Sven and myself how to move forward with netlink and namespace support.
We concluded that having proper netlink support would be the more future proof option. We would then keep debugfs but slowly phase it out in the next coming years. New features would also be adopted in the netlink implementation.
It was also our impression that having the namespace support within netlink would be the cleaner approach, although it takes more work because it requires the netlink and appropriate userspace changes.
Andrew, what do you think? Would you like to check and rebase on Matthias' patchset?
I agree about debugfs. As i already said, i've played with netlink and netns. I changed my debugfs patch, so that it only creates files for the default netns. For all other netns, debugfs operations become a NOP, and you need to use netns.
