If I test it, it would be in Germany, and I really doubt that relicensing one copyleft to another can ever cause puntative damages here. You are only entitled to collect damages here when you have actual losses (that's why Harald Welte never gets a dime except for his defense expenses and voluntary donations to the FSF), but you can demand compliance. That would basically mean that the hypothetical linux-something.subversion-bp with GPLv3 parts in it can't be shipped further, because I can't fulfill all my obligations. It's probably completely hypothetical, but if I really liked to be nasty, I could release the blackfin sound driver I've written for our digital amplifyer under GPLv3 or later. The code I've modified is explicitely under GPLv2 or later. > Just make > sure to test it yourself - giving somebody else an advice that will land > them in trouble is not nice... As a non-lawyer, I can't give anybody legal advice in Germany, and I'd like to extend that to the rest of the world. This is my opinion, my interpretation of the GPLv2 and what's my logical reasoning what these three lines on top of /usr/src/linux/COPYING really mean. And there are only two possibilities: * Either it means what it says, then it's quite likely a copyright infingement done by Linus to all those authors of linux-2.4.0-test8 and before, and you all may need to stop distributing Linux*, since you can't meet your obligations (and restart from linux-2.4.0-test8, which is the last legal version), or * it does not exactly mean what it says, then you still can distribute Linux, but you can't really stop anyone who's updating it to GPLv3 - except for those few files that have explicit version numbers assigned. BTW: If I grep through Linux, I find two files where you have noted your copyright and the release conditions (GPL v2), and I think last time I did the same thing, I found two GPLv2-files, as well - all other files with "Al Viro" in it apparently have multiple authors. These two files may be the same ones, or maybe there are two other files, making it four in total (or some further I missed, the text of v2 only is not as normed as the text for "v2 or later", but in general it's rare). These files clearly have to be rewritten or premission has to be asked when updating COPYING to GPLv3. But that's not a show-stopper. Example, to test the legal issue: /usr/src/linux/drivers/net/bmac.c is Copyright (C) 1998 Randy Gobbel, and was modified by you in 1999, and has no specific GPL license. That's both before 2.4.0-test9, so without the implied "v2 only" of the "tree root". If I take this file up to GPLv3, what can you do against it? Nothing. What can Randy Gobbel do about it? Nothing, either. If you claim, it's "v2 only", Randy Gobbel could do something (e.g. asking puntative damages from you in the US, or denying you the right to redistribute Linux further, because you don't fulfill your obligations). *) e.g. Microsoft lawyers will hunt down all pre-2.4.0-test9 copyright holders and pay the one who's willing to stop Linux a billion. -- Bernd Paysan "If you want it done right, you have to do it yourself" http://www.jwdt.com/~paysan/
