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