[User-mode-linux-devel] Networking via slirp

[Mikko J R. <mjr...@cc...>]

Greetings

I was wondering if anyone has considered adding slirp networking support
to UML? For those who haven't heard of it, slirp is a SLIP/PPP emulator
that works completely in user-space, providing IP-Masqueradish
functionality to a single SLIP/PPP peer. It would sort of complement the
user-space kernel by providing (limited, but for many purposes functional
enough) user-space networking, the obvious bonus being the ability to run
a networked UML completely without root priviledges.

I guess, from glancing at the source, that it'd mostly be a case of
modifying arch/um/drivers/umn_user.c so that instead of calling ifconfig
slirp would be started and its stdin/out used instead of the tty allocated
for the slip line? Any obvious flaws in this?

I'd of course be interested in knowing if anyone has already done or is
doing something to this effect? Who would I bug (Ger Off?) if I get to
scratching my own itch but am not really sure how to best go about doing
it? (Read: not much kernel/low-level programming experience.)
