Ugh... this sounds ugly. This should be forbidden. I mean, what are
things like EXPORT_SYMBOL_GPL for if drivers are allowed to patch
whatever they want?

If the binary blob knows enough about the innards to be able to do binary
patching, it's a derived work and should be GPL.


Unless the offset of an unexported symbol relative to an exported one is simply a "fact" which therefore can't be copyrighted.

This sort of thing would probably be unethical, but it might be legal.
