kernel taint

kernel taint

[Qin Tao]

Hi,

I am using redhat7.3 (kernel 2.4.18-3). When I tried to insert a
kernel module, I got the following warning message:

"Warning: loading mymodule.o will taint the kernel: forced load"

I didn't see this problem when I inserted the module to some earlier
version kernels, such as 2.4.15. Does anybody know what does the warning
message mean and how can I modify my module code to avoid that?

Thanks in advance.

  If this is a module in the RH kernel this may just be due to
mislabeling of the license string.  What's the module?

I think you can add : MODULE_LICENSE("GPL"); to avoid to taint the
kernel.

you can find others license in the linux source code.
Restrictive licence or unknown license may taint the kernel too.
