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