Now, if we do want to disallow gpl module loading after ndis-wrapper has
been used then fine

The problem is we do the dynamic link at module load time. We would have
to unlink the module if it tried to taint itself, which is clearly not
what the end user needs to suffer. Having the taint function actually
taint and printk + return a "Linked gplonly you can't" error seems the
better solution.

Really ndiswrapper shouldn't be using _GPLONLY symbols, that would
actually make it useful to the binary driver afflicted again and more
likely to be legal.

I'm confused on the discussion:
legal? I don't find how a windo$e driver can be "derived work" of Linux,
and anyway they use a "standard" interface. So it is acceptable for GPL
(IMHO and IANAL). so it is not a legal problem.

I see only a development question:
should we allow untrusted module to know and modify the
"intimate" part of kernel, and cause compability and other large
amount of problems into kernel developers, distribution and users?

So it is a political question, not a legal question!
