Ah, so Keith has become (self) nominated license God for the kernel?
Being included in the kernel source isn't "general source availability"?
I can see that you want to make this whole tainted-kernel mess work,
but I think you are confusing intent with implementation. The intent
(AFAICS) is to mark the kernel tainted ONLY if a closed-source module
is loaded, rather than to be a "license police" mechanism, especially
for sources that have been included in the kernel for a long time.
Rather than make the MODULE_LICENSE() a string that people just fill in
(which as your example shows also has problems with spelling and such)
you could have a few pre-defined values to make things easier:
#define LICENSE_STRING_GPL "GPL"
#define LICENSE_STRING_DUAL_BSD_GPL "Dual BSD/GPL"
#define LICENSE_STRING_DUAL_MPL_GPL "Dual MPL/GPL"
#define LICENSE_STRING_BSD_KERNEL "BSD without advertising clause, kernel source"
This not only means we avoid problems with spelling (which will mark a
kernel as tainted, even if it says "GNU GPL" or similar, and makes keeping
the values consistent between user-space and kernel space easier. A
NON-TAINTING license string needs to be added for BSD sources that are
part of the kernel.
I totally disagree with the assertion that a module has to be "GPL" in
order to be "OSS free" especially for sources already in the kernel,
so lets not go on a witch hunt for non-GPL licenses in the kernel just
to make this tainted stuff work without adding a new license. There is
enough animosity between the Linux and GPL camps without more fire for
the "GPL is viral, BSD is free" flamewars.
Cheers, Andreas
