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