This also infers that arch/lib will be broken most of the time as
every time the networking stack references a new symbol it
has to be duplicated into arch/lib.

But this does not mean that your idea is bad, all I want to say that
I'm not sure whether arch/lib is the right approach.
Maybe Arnd has a better idea.

Exactly why I look forward to getting this in-tree.  Jeremy Kerr and I
wrote nfsim back in 2005(!) which stubbed around the netfilter
infrastructure; with failtest and valgrind it found some nasty bugs.  It
was too much hassle to maintain out-of-tree though :(

I look forward to a flood of great bugfixes from this work :)

IIRC, the ability to run UML under valgrind was also one of its key features?
And that's not limited to networking.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
