[HELP] Advising on GPL license issue

Bogdan-Andrei Iancu-2
Hi all,

As I'm not an expert in this, I'm looking for someone to advise on a
more complex issue regarding GPLv2 license.

Shortly - developing an opensips module that needs to link to a non-GPL
(and not compatible) library (available for public in binary format,
with proprietary license).

For details or whatever feel free to contact me offline, not a problem.

Help will be highly appreciate not only be me, but by the project and
community (as a really nice feature depends on finding a solution here).

Regards,

Hi Binan,

Already when through that page, but not 100% clear.

As I understand it, to make it possible you should :
    1) the copyright holders of the GPL code should agree on an exception to link against the non-GPL lib
    2) owner of the non-GPL lib you give you the permission to use it (if not fully public).

Hi Binan,

And this exception clause (btw, found something similar here http://lists.debian.org/debian-legal/2004/05/msg00595.html), needs to be stated by the copyright holders of this new opensips module (that will link to the lib) or by all copyright holders from core + module ? This is the tricky part :)

Re: [OpenSIPS-Devel] [HELP] Advising on GPL license issue

Binan83
Hi Bogdan,

I think Opensips modules are considered derivative to the core ( OpenSIPS module needs "help" from the core. It is not stand alone  ). 

Special exception clauses can only be applied to an original  work and never a derivative. If the core is linked to the lib then all the copyright holders of the core states the exception.

You can go around this by considering this module as part of original work not derivative. In this case we backed to above (All must state the exception).

This must be confirmed by IP lawyer.

Re: [OpenSIPS-Devel] [HELP] Advising on GPL license issue

Bogdan-Andrei Iancu-2
Hi Binan,

Just to clarify on the "module" thing - an OpenSIPS module is a shared library that is dynamically loaded by OpenSIPS core at runtime. So, there is no linking between core and modules, but they share and use code.

Secondly, the non-GPL lib will link only to an OpenSIPS module, without being linked or used at all by the core part.

Maybe this will help a bit .

Hi Binan,

I found that page in the very beginning of my search and, indeed, it provides really useful information on this case.

About the statement, I understand that "affected code" is the code that uses (directly or indirectly), compiles or links against the library - which will be the opensips module. Correct ?

Hi Brett,

Well, looking on the Todo list for 1.9, it may be clear what is about - the Sangoma driver module. There is not need for anyone to die here ;)

The suspense is killing me! :)  Bogdan, would love to hear more about your endeavor here. :)

Hi Binan,

I found that page in the very beginning of my search and, indeed, it provides really useful information on this case.

About the statement, I understand that "affected code" is the code that uses (directly or indirectly), compiles or links against the library - which will be the opensips module. Correct ?

Hi Bogdan,
So OpenSIPS module is not derivative.

I have found this page : http://people.gnome.org/%7Emarkmc/openssl-and-the-gpl.html
and at the end : "all the copyright holders for the affected code agree"
and

Hi Binan,

Just to clarify on the "module" thing - an OpenSIPS module is a shared library that is dynamically loaded by OpenSIPS core at runtime. So, there is no linking between core and modules, but they share and use code.

Secondly, the non-GPL lib will link only to an OpenSIPS module, without being linked or used at all by the core part.

Maybe this will help a bit .

Hi Bogdan,

I think Opensips modules are considered derivative to the core ( OpenSIPS module needs "help" from the core. It is not stand alone  ). 

Special exception clauses can only be applied to an original  work and never a derivative. If the core is linked to the lib then all the copyright holders of the core states the exception.

You can go around this by considering this module as part of original work not derivative. In this case we backed to above (All must state the exception).

This must be confirmed by IP lawyer.

Hi Binan,

And this exception clause (btw, found something similar here http://lists.debian.org/debian-legal/2004/05/msg00595.html), needs to be stated by the copyright holders of this new opensips module (that will link to the lib) or by all copyright holders from core + module ? This is the tricky part :)

Yes .
Special exception clauses allows this combination (linking). This is what i know.

Hi Binan,

Already when through that page, but not 100% clear.

As I understand it, to make it possible you should :
    1) the copyright holders of the GPL code should agree on an exception to link against the non-GPL lib
    2) owner of the non-GPL lib you give you the permission to use it (if not fully public).

?

Hi all,

As I'm not an expert in this, I'm looking for someone to advise on a more complex issue regarding GPLv2 license.

Shortly - developing an opensips module that needs to link to a non-GPL (and not compatible) library (available for public in binary format, with proprietary license).

For details or whatever feel free to contact me offline, not a problem.

Help will be highly appreciate not only be me, but by the project and community (as a really nice feature depends on finding a solution here).

Regards,
