the kernel modules provided by Tuxedo on
https://gitlab.com/tuxedocomputers/development/packages/tuxedo-drivers
are licensed under GPLv3 or later. This is incompatible with the
kernel's license and so makes it impossible for distributions and other
third parties to support these at least in pre-compiled form and so
limits user experience and the possibilities to work on mainlining these
drivers.
This incompatibility is created on purpose to control the upstream
process. See https://fosstodon.org/@kernellogger/113423314337991594 for
a nice summary of the situation and some further links about the issue.
Note that the pull request that fixed the MODULE_LICENSE invocations to
stop claiming GPL(v2) compatibility was accepted and then immediately
reverted "for the time being until the legal stuff is sorted out"
(https://gitlab.com/tuxedocomputers/development/packages/tuxedo-
drivers/-/commit/a8c09b6c2ce6393fe39d8652d133af9f06cfb427).
As already being implied by that commit message, this is sadly not an
issue that can be sorted out over night.
We ended up in this situation as MODULE_LICENSE("GPL") on its own does
not hint at GPL v2, if one is not aware of the license definition table
in the documentation.
That statement isn't consistent with you saying to pick GPLv3 as an
explicitly incompatible license to control the mainlining process. So
you knew that it's legally at least questionable to combine these licenses.
The only thing I could accept here is that you were surprised that the
incompatibility has some technical enforcement resulting in your modules
to become nonfunctional. But that's like a thieve in a supermarket who
asks for forgiveness because while he was aware that steeling is not
allowed, wasn't aware there is video surveillance that might actually
catch him.
So I'd claim MODULE_LICENSE("GPL") not being explicit to not apply for
GPLv3 code is not a valid excuse. (Which doesn't mean the kernel
couldn't improve here.)
Best regards
Uwe
