    Posté par . En réponse à la dépêche Sun "libère" 1600 brevets pour les projets sous CDDL. Évalué à 5.

    > licence CDDL (NdRl : cette licence est qualifiée de libre par la FSF).

    Il y a "libre" et "libre". La licence est considéré "Open Source".

    Elle a été "validée" par http://www.opensource.org/(...) (je n'ai pas regardé du côté de la FSF) :

    > cette licence est qualifiée de libre par la FSF

    Il serait bien de mettre un lien pour affirmer ça.

    > Sun "libère" 1600 brevets pour les projets Open Source

    NNOONN !!!

    C'est uniquement pour les logiciels sous CDDL (en tout cas, il y a un gros flou). Or cette licence est incompatible avec la GPL :
    http://lwn.net/Articles/114839/(...)
    This license is GPL-like in its intent, but (as Sun acknowledges up front) it is not compatible with the GPL. There are certain extra terms in the CDDL which, while not necessarily objectionable in their own right, conflict with the GPL's "no additional restrictions" terms. This incompatibility came as a surprise to few people; nobody has ever expected Sun to encourage the mixing of Solaris and Linux kernel code.
    (...)
    The CDDL licenses the copyrights in the code for use, distribution, and modification - the usual free software rights. It also contains a patent grant, but here the language is a bit more constrained:

    (b) under Patent Claims infringed by the making, using or selling of Original Software, to make, have made, use, practice, sell, and offer for sale, and/or otherwise dispose of the Original Software (or portions thereof).


    In other words, the CDDL does not license any patents for use in derived products. Other terms in the license suggest that Sun is concerned about patent infringements caused by modifications, but the above exclusion is not restricted to such infringements.

    (...)

    The CDDL contains patent defense language: if you sue a copyright holder for patent infringement, you can lose your rights to use the code under the license. In any patent litigation settlement talks, the value of the patent license granted by the CDDL must be taken into account - essentially, the party initiating the lawsuit loses any patent license granted by the CDDL. There is one other strange term:

    6.4. In the event of termination under Sections 6.1 or 6.2 above, all end user licenses (excluding distributors and resellers) that have been validly granted by You or any distributor hereunder prior to termination (excluding licenses granted to You by any distributor) shall survive termination.


    So if you are a software distributor, and you got the code from somebody who later turns around and sues Sun, you can lose your rights to the software under the license.

    "The CDDL is not expected to be compatible with the GPL, since it contains requirements that are not in the GPL," Claire Giordano of Sun's CDDL team said in its submission. "Thus, it is likely that files released under the CDDL will not be able to be combined with files released under the GPL to create a larger program."



    Je n'ai pas lu la lkml pour savoir si les développeurs Linux ont un avis.

    Pour ma part. Cette annonce et cette licence a peu ou aucun intérêt pour le logiciel libre. Solaris sous CDDL n'est pas du logiciel libre. C'est du logiciel à "source ouverte" et ce n'est pas la même chose.
    M'enfin, c'est mieux que pas de source du tout. Ne boudont pas le geste de Sun mais il faut bien l'évaluer.
