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.
It is copyright infringement. Nvidia (and everyone writing kernel modules) has to choose between:
Remember that the kernel is maintained by volunteers and by engineers funded by/working for many companies, including Nvidia’s direct competitors, and Nvidia is worth billions of dollars. Nvidia is incredibly obnoxious to infringe on the kernel’s copyright. To me it is 100% the appropriate response to show them zero tolerance for their copyright infringement.
