    • +Some vendors distribute binary modules (i.e. modules without available +source code under a free software license). +As the source is not freely available, any bugs uncovered whilst such +modules are loaded cannot be investigated by the kernel hackers. All +problems discovered whilst such a module is loaded must be reported +to the vendor of that module, not the Linux kernel hackers and +the linux-kernel mailing list. The tainting scheme is used to identify +bug reports from kernels with binary modules loaded: such kernels are +marked as "tainted" by means of the MODULE_LICENSE tag. If a +module is loaded that does not specify an approved license, the kernel +is marked as tainted. The canonical list of approved license strings +is in linux/include/module.h.
      +"oops" reports marked as tainted are of no use to the kernel developers +and will be ignored. A warning is output when such a module is loaded. +Note that you may come across module source that is under a compatible +license, but does not have a suitable MODULE_LICENSE tag. If you +see a warning from modprobe or insmod for a module +under a compatible license, please report this bug to the maintainers of +the module, so that they can add the necessary tag. +
