Darren Reed, l'auteur de IPFilter, très controversé ce temps ci, vient de changer sa licence :

"The licence is intended to mean that people can use (which includes
modify or patch or tune, as seen fit) IPFilter as found within FreeBSD/NetBSD for whatever purpose they desire"

Il a bien entendu oublié open, bsd/i, mac os, et les autres "embedded".

Vous pouvez mieux cerner le personnage, en cherchant par exemple, la raison pour la quelle IPFilter s'est arrêté sur la 2.0 de Linux ;-)

    N'oubliez pas de garder une petite place sur LinuxFR pour le prochain changement de licence. A ce rythme, cela devrait arriver d'ici 3 ou 4 jours :o)

    Il n'y a vraiment rien de mieux qu'une bonne GNU GPL.

          On pourrait meme aller plus loin en se demandant pourquoi certains choisissent d'autres licence que la GNU GPL, s'ils désirent publier un logiciel libre selon les normes du GNU...

          Pour pouvoir retourner leur veste ? Ambiguité par hasard ou pas ?

            Darren says so, however "angry words" are not what are at issue. What
            is happening is this:

            All the various licenses on ipf (there are a couple now) make it clear
            that it is not Open Source (www.opensource.org) or Free Software (ask
            the FSF). Go read the rules for yourself.

            If source code does not permit _modification_ and _distribution_ by
            any and all parties for any and all purposes, it is not completely
            free.

            Come on, go to www.opensource.org and read the rules!

            And, if it not completely free, then it does not belong in any project
            that claims to only include free code.

            That includes all the BSD projects and also many Linux projects.

            This isn't something new; it is just a mistake that was made. Other
            things with similar licenses are being resolved now, for instance: tcp
            wrappers (from Wietse), yacc test stuff, cron's popen.c file,
            login_fbtab (from Wietse's logdaemon code), and md5 from RSA. All of
            these have already been fixed now either by replacing the code or by
            the authors changing the license. Others have to be fixed too: the
            multicast daemon toolsets (Xerox, Stanford, USD), rpc.pcnfsd (Sun),
            slstats and pppstats (LBL), pppd and ppp code (various copyright
            holders), and parts of tcpdump and lex. It's going to be a lot of work.

            But we make a promise that we try to release free code. I am sure
            that most of the authors of the above packages had no idea that
            modification has to be explicity granted for stuff to really be free
            software; and like Wietse once they become aware they will react with
            "Oh, of course I wanted it to be free, here is a new license that permits
            modification".

            Darren has chosen not to change his license to permit modification.
            That is OK; it is HIS decision for a license on HIS work.

            We are not forcing him at all. There's no point in talking to him
            about this (and why would I want to, since he's all over various chat
            forums doing character assasination of me and the OpenBSD project,
            suggesting that we tried to "force" him).

            > the reasons I even use BSD. But this is my opinion. Where do the project
            > leaders see this issue going? Is Darren's license so unreasonable?

            No, his license is completely reasonable. It's his software. He can
            set his license to anything he wants. However, it conflicts with the
            license on software that is included in OpenBSD. Hence, out of
            respect for his wishes as written in his license, we are not permitted
            by our Open Source/Free Software rules from including ipf in the
            future.

            > Is it
            > different from the copyright held by Theo on the layout of the cd?

            Outside of what copyright law says, this is very different. The
            copyright on the CD is on layout and paid-for artwork. The intent of
            using copyright law to retain ownership varies from work to work: In
            our case, this is to discourage other vendors from simply taking our
            layout efforts which we go through every 6 months, and distributing
            CDs using that layout; our project needs to see money from our
            product. We need that money. It ensures that we keep doing that. We
            make stuff available on the FTP sites. (What do YOU give me for free?)

            > this thing just be resolved amicably so both parties are happy? I am sure

            It cannot be resolved. It is not our right to bother Darren with
            pleas or other comments as to his license. I suppose you people can,
            since it bothers you. It doesn't bother us: we had no option, since
            the rules are clear.

            We either had to remove ipf, or we had to remove comments on our web
            pages which say that we "try to provide an operating system that
            anyone can use for any and all purposes".

            Which would you rather we remove?

            If you don't understand why the level of freedom that we are striving
            for is important, perhaps ask yourself why 99.9% of our source tree
            has licenses that permit anyone to do anything; and only 0.1% doesn't,
            and these are now either being repaired or replaced. This isn't just
            me -- our entire development community believes in the importance of
            this. This freedom came out of the University of California CSRG, and
            it is the foundation that permitted us to take the original code from
            4.4BSD and start working on it; It is also the foundation which
            permits companies like NFR to take OpenBSD and build it into a product
            without having to hire a cadre of laywers "asking for permission"
            component by component. If you don't understand that, then fine --
            this fanatical level of freedom is something that we (CSRG, and now
            the *BSD projects) been striving for for almost 15 years. Accept it.

            Recently Darren has said this in mail:

            > The licence is intended to mean that people can use (which includes modify
            > or patch or tune, as seen fit) IPFilter as found within FreeBSD/NetBSD for
            > whatever purpose they desire - so long as the conditions (due credit and the
            > notice) are met.

            I want to reiterate that this is not an Open Source or Free Software
            compatible license. It specifically says who the software is free
            for; it does not say that it is free for anyone and everyone.

            Have you gone to www.opensource.org yet and carefully read the rules
            for Open Source?

            Don't believe me? Ask Eric Raymond, or Richard Stallman.

            I don't think I will comment on this again; because it is pretty
            boring and taken care of. I have other stuff to do that is far more
            interesting.

            Open Source means some restrictions apply, limits are placed, often quite
            severe. Free Software has _no_ serious restrictions. OpenBSD is Free Software.

            Il n'y a pas que GNU dans la vie. Des licenses telles que LGPL, BSD, Apache ou Artistic garantissent autant que la GPL la liberté d'utilisation, de modification et de redistribution du code.

            Pour ceux qui ne l'aurait pas déjà lu 250000 fois ipf n'a jamais été sous une licence libre puisqu'il n'a jamais été permis de distribué une version modifiée.

            Je ne suis pas sûr non plus que le fait de distribuer un logiciel en GPL interdise à l'auteur de celui-ci de changer de license à un instant donné. Bien sûr cela n'affectera pas les versions précédentes mais je pense que cela peut s'appliquer aux versions après le changement.

              bah si.
              La nouvelle version utilisera des morceaux de l'ancienne version GPL, a ce moment la cette nouvelle version devient GPL...
              A moins de reecrire tout le code differemment, c'est pas trop possible...

                Non, tu devrais relire la GPL.

                Preuve s'il en est, IglooFTP est passé il y a un an de GPL à une autre licence. Va jeter un oeil du côté des archives des liste Debian de cette époque pour voir ce qu'ils en ont dit.
                http://www.geocrawler.com/archives/3/208/1999/7/0/2479511/(...)

                QT est à la fois disponible en GPL et en licence QPL.

                L'auteur décide de faire ce qu'il veut avec sa licence. Il ne peut pas interdire à quelqu'un d'utiliser le code de la version GPL, mais personne ne peut le forcer à continuer à utiliser la GPL car il est celui qui décide de la licence.

    Amusant, Darren Reed s'inquiétait en 1997 au sujet de Linus et du noyau de Linux :

    http://lists.gnac.net/firewalls/mhonarc/firewalls.199711/msg00058.h(...)
    "I'm not sure that this puts Linux in a more favourable light. If he gets hit by a bus or is otherwise incapacitated for a length of time, are you saying that Linux would suffer as a result ?"

    Et quand on lui pose maintenant la même question, voici sa réponse :

    http://false.net/ipfilter/2001_05/0348.html(...)
    ">What will happen to ipfilter
    >if you get hit by a bus?
    I won't care, I'll finally get to RIP."

    Amusant, non ?
