Its even worse - The problem with the tunneling ioctls is that gre, ipip and sit are all using the private ioctls which can not be emulated due to there non uniqueness. To split this up one has to seperate SIOCGETTUNNEL into the SIOCIPIPGET, SIOCGREGET and SIOCSITGET which naturally will break all userspace apps. I just produced a patch which exactly does this BUT provides backward compatibility for the private ioctls. Problem now is that all tunneling ioctls are nearly the same and not that small. One would have to duplicate the already duplicate code into the sysctl32.c which would result in big bloat and bad maintainability. A definitly better solution would be to follow the advise in the ip_gre.c which says to unify the tunnel ioctls in some way into some ip_tunnel.c. By unifying a good point would be to seperate the pure "get_user/put_user" stuff from the "do really something" parts so that the emulation in sysctl32.c could use the parts that really do something without duplication.
