Related reading: https://lwn.net/Articles/860262/ https://lwn.net/Articles/860262/ Key takeaway: > purveyors of proprietary modules have engaged in a number of tricks to get around GPL-only exports There are many technical workarounds possible still. You could scan the kernel binary for byte patterns and build your own export list. How will the kernel maintainers plug that hole? (Maybe they can implement compile-time binary obfuscation, and sacrifice performance to stop proprietary code, wouldn't that be funny?) I think that these efforts to prevent (what the kernel developers see as) "license infringement" through technical means sort of reveals that they don't really think that the line of reasoning would hold up in court.
