I am working with a company that wants to utilize librbd in a project to
interact with Ceph storage. For the purposes of this integration,
LGPL-licensed open source code is acceptable, but GPL-licensed code is not.
Well, at least not without other changes to the project, which can be
accomplished if necessary.

The COPYING file distributed with the Ceph source code seems to indicate
that librbd would fall under LGPL 2.1, but some of the source files in
librbd reference GPL 2.1 in their copyright headers.

From what I have found so far, it appears to me that the sources in
question were probably originally LGPL, but were switched to GPL a few
years back to comply with FUSE licensing, which is GPL. Is my understanding
correct that these librbd source files are now GPL? If so and FUSE is the
reason behind it, is it possible to dual-license those files so they could
be LGPL when not used with FUSE?

I just want to make sure I understand the licensing properly. I apologize
if this has been discussed previously. I am new to the list and can't seem
to get the archive search feature to work.

Steve

Which files?  If there are disparities we should correct them. To the best 
of my knowledge everything in librbd is LGPL.

Thanks!

Sorry, my previous reply was rejected by the list because it wasn't in
plain text. Let's try again.

librbd.cc:

librbd.h:

librbd.hpp:

 */

These are the three that I've noticed poking around librbd so far. My
understanding from COPYING is that they should be LGPL, but these
copyright headers obviously state GPL instead. I'm just trying to
understand definitely which it is. :)

If a change is in order, of course I'll be happy to make the change
myself and submit a pull request if you like.

Hi,

The missing "Lesser" is a nice typo :-) There has never been a GPLv2.1 ( https://en.wikipedia.org/wiki/GNU_General_Public_License#Version_2 ) and I guess it helps disambiguate the interpretation.

Cheers

Fair enough. Thanks for clearing it up. Is this something anyone cares
to fix? I'm personally happy to accept it as is with this email chain
as reference, but I will also be happy to add the "Lesser" and submit
a pull request if you want it. I'm not big on changing other peoples'
copyright headers unless they ask for it though. :-)

Ideally the change comes from Josh, who originally put the notice there, 
but I think it shouldn't matter.  We relicensed rbd.cc as LGPL2 a while 
back (it was GPL due to a header we used?) and got confirmations from all 
authors.  It might be worth doing a quick check to make sure there aren't 
committers for the affected headers that we didn't contact earlier.

For reference, the license change commit is 
2206f55761c675b31078dea4e7dd66f2666d7d03.

There's one.

Greg, could you confirm that you consent to licensing your changes to
librbd.h and librbd.hpp under LGPL2.1?

I think it's a good idea to fix the typo so it doesn't cause this
confusion again.
