Re: compatibility of OpenSSL and GPL'ed plugins

2004-07-17 Thread Florian Weimer 
* Marco d'Itri:

 Let's consider a program, released under a MIT/X11 license and linked
 with OpenSSL. Some GPL'ed plugins (which are dlopen'ed at run time) are
 distributed with the program.
 Is distribution of this package a GPL violation?

If the plug-in is written from scratch (so it doesn't contain 3rd
party GPLed code) and it's specifically written as a plug-in to the
program, I'd suppose that the author implicitly gives permission to
dynamically link it to the program (and other plug-ins).

If one of the conditions don't apply, it's a tough question. 8-)

Or, it may be the author's intent to only permit source distribution.
Assuming that the author doesn't understand the consequences of his
chosen license is not a sound legal strategy.

 If they are distributed with the program (in the same tarball) and
implement important features of the program, the terms of the GPL would
apply to the whole package, so there would be a license incompatibility.

The plugins are actually a modified version of standalone applications,
so I'm not sure if they could be considered derived works of the
program, but then I'm not sure if this is relevant at all.

Let's consider what program?

As I understand it, there's unlikely to be a problem unless the 
originally GPL'd plugins are accessing the OpenSSL library's functions 
and data structures and even that looks like a lawyerbomb rather than 
certain. http://www.gnu.org/licenses/gpl-faq.html might help you, or 
[EMAIL PROTECTED] if there's a GNU package involved.
