What license is multipath-tools under

What license is multipath-tools under

Hi,

I just ran some compliance tools on multipath and the results weren't very
appealing in regard to licensing and copyright information.

The standard COPYING file mentions LGPL v2.
On the other hand, the majority of the source code has no license mentioned in
its header. Some that do have, mention it as GPLv2, and some as GPLv2+

Please see full license/copyright check below.

"No copyright" or "UNKNOWN" files should be covered by COPYING licence(LGPL v2).
Except:

kpartx/
It comes from partx(util-linux), and these files are under "GPL v2" or
"GPL v2 or later". Independent binary.


libmultipath/prioritizers/ontap.c
It's "GPL v2". But it's a plugin. ???


libmultipath/checkers/cciss_tur.c
Source says "GPL v2 or later", and:
/*
 *  This program originally derived from and inspired by
 *  Christophe Varoqui's tur.c, part of libchecker.
 */
At libmultipath/checkers/tur.c there is no licence, but it's derived from src/sg_turs.c
from sg3_utils. And this one is under "GPL v2 or later". But it's a plugin. ???


libmultipath/memory.c
libmultipath/memory.h
libmultipath/parser.c
libmultipath/parser.h
libmultipath/vector.c
libmultipath/vector.h
These comes from keepalived, and they are under "GPL v2 or later".


libmultipath/version.h:
"GPL v2 or later".


libmultipath/file.c
libmultipath/alias.c
Source says:
/*
 * significant parts of this file were taken from iscsi-bindings.c of the
 * linux-iscsi project.
And they are under "GPL v2 or later".


libmultipath/uevent.c
libmultipath/sysfs.c
These come from udev, and they are "GPL v2".


GPL code can not be mixed with LGPL code. So I guess libmultipath/ files are "GPL v2" ???


multipath/main.c
Under "GPL v2 or later". It's linked with libmultipath.so and libmpathcmd.so.

Thanks Xose, for digging this information. But shouldn't this information go
into respective source files?

Recently, at Debconf, I came aware of Fossology [1]. It is a compliance tool for
license, copyright and export control scans. I have spawned off a job [2] and am
curious of the result. But looks like their server may be having a problem at
the moment.

But it is standard practise in most Free Software projects to define the
licensing proper. And for a project with mixed licenses, it'd be best to have
individual source files mention their license.

If there's a COPYING file, there's no need for individual files to have
a copyright.  The licence of the file defaults to whatever COPYING (or
LICENCE or some recognizable top level file says).  A significant
number of Linux Kernel files don't have individual file header copyrigh
ts, if you want an example of this.

It may be a best practice and even practised by some projects, but if
Linux doesn't do it, it's hard to say it's standard practice.

Yes. But as I understand, the entire Linux [1] code base is GPLv2 only. Whereas
in case of multipath-tools, as Xose mentioned in the previous email, it is a mix
of:

* GPLv2 (only?)
* GPLv2+
* LGPLv2

Having this information in the source repository (not necessarily as individual
source headers) will speak out much clear.

I think something like Debian's Machine-readable copyright format will be a good
fit in this case.

https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/

An example project, with mixed licenses:
http://metadata.ftp-master.debian.org/changelogs/main/libs/libstoragemgmt/unstab
le_copyright

BTW, this topic hit my mind 2 days ago when I looked at the aging (old format)
multipath-tools/debian/copyright in my packaging repo and wanted to fix it.

http://metadata.ftp-master.debian.org/changelogs/main/m/multipath-tools/unstable
_copyright



I have attached a patch for a copyright file, based on what Xose had mentioned
in the email. There still are files, like libmultipath/prioritizers/alua.c,
which mention the license as plain GPL. So, this patch is still not complete.


[1] with some minor exceptions I just noticed.

No it's not: We have a ton of dual licenced files (dual GPL/BSD is the
most common) and quite a few GPLv2+ ones.  Of course, all of those have
headers explaining the difference from COPYING (or at the very least
MODULE_LICENSE tags).

This is also rather common.  Look at the COPYING file of the CRIU
project for instance

https://github.com/xemul/criu/blob/master/COPYING

It has a split GPL/LGPL model depending on which directory the file is
placed in.

That's up to the maintainer of multipath-tools.  I was just point out
that doing this isn't required or even standard practice.
