Luis Chamberlain sent out the modules changes today for the Linux 6.6 merge window. Most notable with the modules update is a change that better builds up the defenses against NVIDIA’s proprietary kernel driver from using GPL-only symbols. Or in other words, bits that only true open-source drivers should be utilizing and not proprietary kernel drivers like NVIDIA’s default Linux driver in respecting the original kernel code author’s intent.
Back in 2020 when the original defense was added, NVIDIA recommended avoiding the Linux 5.9 for the time being. They ended up having a supported driver several weeks later. It will be interesting to see this time how long Linux 6.6+ thwarts their kernel driver.
There are lots of problems here. First, if you have to “hack” something to get the code, then it likely invalidates your own defense that you thought you were allowed to release it. Second, even if you can prove that nVidia knows that they should have to GPL their code, you still have no legal right to hack something to get it. If the hacking is illegal, then it’s illegal, even if it’s done to enable an otherwise legal activity.
