But an unpatched UML won't work with a newer uml_net binary (for SLIP usage only and only for closing the interface, I mean), right?
Correct. I think uml_net would need to manage a database of who opened what to do what you suggest.
I also looked at the versioning for uml_net, but what happens is that we can
only stop unpatched uml_net from working with newer UML for any protocol, not
anything else. So I won't change that. However, I just saw that we did it
correctly until Version 3 of the uml_net protocol...
I wonder what has happened after.
I'd like to know this too. It is odd that it was only the shutdown of the interface that changed, it worked perfectly well before.
> Agreed, tuntap is a compile time option, slip should be as well. Ok... tuntap is compile-time because of a rough check for host support.
Yes, but uml_net is suid. I may not want my users to be able to set up slip devices on their own (why? I don't know, I'm just paranoid that way).
