That is, if there's a BSD licensed module for device FOO, and I port it to the Linux kernel, that will need to have a GPL added to it to be included in Linux. But the original BSD code is not affected. If a fix is made to the GPL Linux version, I'm assuming (because I've been asked when doing something like this), that the author of that fix will have to give it a dual license to be used back in the original BSD only code. Correct? I'm just trying to understand this. From what would make sense to me (but may or may not to a court of law, where it counts), is that the code added to Linux must be under GPL. But using that code depends on where you get it from. If you use BSD source, it stays under BSD. But any fixes to the GPL version will require permission to be put back to the BSD version. A change to the GPL version doesn't automatically get allowed back to the BSD only version? -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
