A new patch series posted today to the Linux kernel mailing list would block kernel modules/drivers from TUXEDO Computers from accessing GPL-only symbols in the kernel.
TUXEDO Computers maintains a set of kernel drivers currently out-of-tree for their various laptops for additional functionality around power profiles, keyboard backlight controls, WMI, sensor monitoring, the embedded controller, and other functionality. They have said they want to eventually mainline these drivers but in the name of allowing for rapid hardware support they maintain them out-of-tree and ship them with their Ubuntu-based TUXEDO OS and also have the driver sources available via GitLab.
The issue at hand though is that these kernel drivers marked as GPLv3+ and that conflicts with the upstream Linux kernel code licensed as GPLv2. There was a commit to change the driver license from GPLv3 to GPL(v2) but was reverted by TUXEDO Computers on the basis of “until the legal stuff is sorted out.”
GPLv3 is less proprietary than GPLv2, in the sense that it does a better job at protecting end-users from being abused by device makers that would try to close up their Linux-based system.
Only if those device makers are willing to use it. And that has always been the tightrope linux has walked.
Its very history as a x86 platform means it has needed to develop drivers where hardware providers did not care. So that code needed to run on closed hardware.
It was bloody rare in the early days that any manufacturer cared to help. And still today its a case of rare hardware that needs no non free firmware.
Free hardware is something I’ll support. But it is stallman et als fight not the linux kernel developers. They started out having to deal with patented hardware before any one cared.
