IANAL, but AIUI: if the changes are made the copyright holder then they may do whatever they want. (release the changes only under one licence, both, none, etc..) if small changes are made by a 3rd party (eg a patch) and submitted back to the copyright holder, then it is almost safe to presume that the copyright holder may incorporate those changes without ceding copyright in any way. (then see first point) if major changes are made by a 3rd party then (i think) 3rd party has copyright over their changes, and so, either: -copyright holder of the original work would need to comply with the licence of the derived work. (eg if GPL, then changes can't go back into the BSD version) or: - copyright holder of the original work would need express permission from the copyright holder of the derived work to use it under a different licence. but IANAL most obviously... :) > > Regards > Henning --paulj - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
