Defendant: my module doesn't use any GPL-only export! Plaintiff: but using XXX normal symbol is a violation too! D: so why have you created that _GPL thing exactly? Additionally: D: top of the COPYING file explicity states binary modules are ok. This is of course fine if we consider normal use of non-GPL-only symbols ok. > They serve as a warning and, as a practical matter, may make it a bit more > difficult to violate the license. Technically only. I have to agree with Alan that the list of non-GPL modules only is quite tiny nowadays. Madwifi is in terminal state, ATI is opening the docs and working on GPL driver, modem drivers are mostly thing of the past, NVidias will probably be supported by the open source driver soon even if they don't open their code. Embedded devices have full Linux, not just modules. -- Krzysztof Halasa -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
