199 * "Proprietary" [Non free products]
201 * Both "GPL v2" and "GPL" (the latter also in dual licensed strings) are
202 * merely stating that the module is licensed under the GPL v2, but are not
203 * telling whether "GPL v2 only" or "GPL v2 or later". The reason why there
204 * are two variants is a historic and failed attempt to convey more
205 * information in the MODULE_LICENSE string. For module loading the
206 * "only/or later" distinction is completely irrelevant and does neither
207 * replace the proper license identifiers in the corresponding source file
208 * nor amends them in any way. The sole purpose is to make the
209 * 'Proprietary' flagging work and to refuse to bind symbols which are
210 * exported with EXPORT_SYMBOL_GPL when a non free module is loaded.
212 * In the same way "BSD" is not a clear license information. It merely
213 * states, that the module is licensed under one of the compatible BSD
214 * license variants. The detailed and correct license information is again
215 * to be found in the corresponding source files.
217 * There are dual licensed components, but when running with Linux it is the
218 * GPL that is relevant so this is a non issue. Similarly LGPL linked with GPL
219 * is a GPL combined work.
221 * This exists for several reasons
222 * 1. So modinfo can show license info for users wanting to vet their setup
224 * 2. So the community can ignore bug reports including proprietary modules
225 * 3. So vendors can do likewise based on their own policies
