    Phoronix: "Very Disruptive" Change Hurts ARM Linux Support

    The Linux kernel is having to remove support for NWFPE and VFP emulation code due to a licensing conflict. Removing NWFPE and VFP from the kernel will effectively render older ARM hardware on Linux useless until a solution is determined...

    Else it would not qualify as successor of GPLv2 or GPLv3, so you could not use code from GPLv2 or later or GPLv3 or later under the hypothetical non-copyleft GPLv3+n.

    Well, answering an edit is hard (we don?t see it?).
    I would love if somebody could explain what would stop the evil company from doing that.

    //EDIT: On the other side if some hole in the GPLv2 gets found and you want the new GPLv4 to apply cause it fixes that hole, who would win in court? You that chooses the option of GPLv4 or some evil company that chooses the option of GPLv2 (cause they simply don't want a later version) to exploit that hole?
    You offered the GPLv2, so they are free to use the GPLv2. A license cannot retroactively take away rights it already granted (and should not, because people might depend on them for good reasons). And if it only gave lime-limited rights, it would not really qualify as free software license?

    But you can use GPLv4 for all future work on the project, so they can only abuse an old version of your code. That?s one of the reasons, why freeBSD is still stuck with GCC 4.2 (as reported here on Phoronix: http://www.phoronix.com/scan.php?pag..._llvmgcc&num=4 ). freeBSD is stuck in GCC code from 2007 and is scrambling for LLVM, because they don?t like the protections GPLv3 offers to users. The same goes for Apple. They have to spend lots of money (=development time) to get the abusable LLVM into a state where it can actually compete with GCC, so by licensing GCC under GPLv3, the GNU folks could actually ensure that abusing users carries a hefty price.

    That wasn't what I wanted to say. But your code would now be dual-licensed under GPLv2 and GPLv4. This would allow Microsoft to use it in proprietary projects.

    Isn't one of the main reasons to use the GPL to prevent your code from being in proprietary projects? Is this no harm for the original developer(s)? But this hypothetical talk is useless:

    It is a clear condition which defines what can be called a revised version, so I?m pretty sure that it has legal meaning.

    But in case you don?t trust judges to see it the same way, GPLv3 includes a second term: You can name a proxy who can take the decision whether a new version of the GPL may be used for your project. But for that you have to use the GPLv3. GPLv2 does not include an option for it.

    Let me give you the full quote:

    Originally posted by http://gnu.org/licenses/gpl
    The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

    Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License ?or any later version? applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.

    If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.

    Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.

    To be fair it says "or (at your option) any later version." - the "at your option" is important, cause that doesn't mean you as copyright holder, it means 3rd parties (the one reading the license text).

    Now look at this (extremely unlikely) scenario:
    1) Microsoft overtakes the FSF.
    2) Microsoft brings out GPLv4, which is just this text: "All codes belong to the Microsoft corp.".
    3) They download your GPLv2 source codes and decide to let GPLv4 apply cause, in their option, it's better than v2.

    //EDIT: On the other side if some hole in the GPLv2 gets found and you want the new GPLv4 to apply cause it fixes that hole, who would win in court?

    Just because Microsoft decides to apply the terms of this new hypothetical GPLv4 to the code doesn't mean that the terms of the GPLv2 under which the code was previously licensed will suddenly become void. That's the whole point of open source, and it's how projects that switched to more closed and restrictive licenses were forked.

    With this, (2) is not (easily) possible: They might call their new License GPLv4, but that would not make it a later version of GPLv3, because it would not be similar in spirit.
    I don't think this has any legal meaning.
