[PATCH rdma-core] Improve global COPYING files

[PATCH rdma-core] Improve global COPYING files

[Jason Gunthorpe]

Upon deeper analysis it seems there are two variations of the 'OpenIB.org BSD
license', I am calling them the MIT and FreeBSD variants. They differ only in
the text of the disclaimer. The MIT version is used widely as the source
license so that version should be the 'default' in the source tree, not the
FreeBSD version I had selected initially.

Retain the FreeBSD version as we will refer to it in future commits.

Elaborate the COPYING file to discuss the license situation in
more depth.

I have reviewed most of the files now for copyright considerations to
make sure our licensing is in order.

This is my proposal for the top level COPYING file, and it contains a
summary of my findings on licensing.

Due to various mistakes in the past things are overly complex, I would
appreciate any patches to reduce the complexity. eg ensuring that all
files have a license reference and the removal of the sub dir COPYING
files.

It would be appreciated if those who hold the copyrights can adjust
their licenses to match the so-called 'Default Dual License', eg by
patching the remaining COPYING files to use the correct disclaimer.

Here is my first jab at simplifying:

I doubt that we have appropriate knowledge to come into meaningful
conclusion after "discussion". It is legal issue which should be
handled by relevant legal departments.

Hi Leon,

I think the commit message was not clear, let me try again:

[PATCH] Document copyright situation and select default license

This patch is not intended to change the copyright or license
situation of any of the original code.

Documentation is provided that identifies the various licenses we
have in the source tree.

The default license for new items after the 'Initial commit' merge is
corrected to match the majority license already in use. This is the
license we recommend all new code use. This corrects a mistake I made
in the 'Unified CMake build system' patch which selected the wrong
license file.

Also provide specific guidance on how the 18 different COPYING files
and per-file copyright headers are intended to be interpreted
within the merged tree.

=======

As you know I've sent emails to various parties on licensing issues,
as those issues are corrected we can update the tree and the copying
summary.

We've already had success correcting one mistake from Intel and
Chelsio, thank you very much to those companies.

It is important we clearly document the current situation so our
downstreams can properly distribute this code.

Jason

I sure that this question will sound dumb for you, but can we unify all
code under OFA's licenses (dual-license)? I don't feel comfortable with
this multi-license situation.

If this combined repo is intended to support the plumbing for the linux-rdma subsystem, then I think it must support code that is submitted under GPL only.  Much of the tradition code can remain dual-license, but new provider code, for example, should be submit-able under GPL.

Hum, I don't think that follows.

My expectation in the kernel is that the entire RDMA subystem and
drivers follows the overall licensing model of the kernel and does not
require userspace to follow any specific license, and certainly does
not require userspace to follow the GPLv2.

I do not support that recommendation.

The FSF has made very clear their position on GPL licensing of plugins
(see https://www.gnu.org/licenses/gpl-faq.en.html), and allowing a
GPLv2 only plugin or library code would break our community's promise
to our customers - that the library core is usable in any application.

It would be a complicated discussion if someone proposed a GPLv2 only
provider.

A LGPLv2-only provider would be more acceptable, and I would encourage
anyone who wishes to have the protections of the GPLv2 in their
provider to go that route. I suspect it would still be controversial.

I would prefer to see us continue with the dual license approach, and
obviously all OFA member companies have agreed to do that.

I agree with Jason here.  Dual license or at least LGPL is needed on
providers because they will be linked to by other programs.  Libraries
shouldn't taint user programs.  But we do have some leaf code in the
overall rdma-core repo.  Things like iwpmd and ibacm.  These could be
licensed GPL only and still be OK.  So I think it's OK for the repo to
support GPL only, we just have to be clear about the fact that GPL only
is not the default as this repo is more about libraries than leaf utilities.

It is an excellent question.

To do this we would need the OFA to talk to each of the member
companies and get them to sign some kind of legal change of copyright
document. Assuming all of the member companies agree, and all the
member companies are the exhaustive copyright owners then the code can
be placed under a single uniform license.

As I understand it all OFA members were required to agree to use a
specific licensing scheme, including specific license text when they
signed the OFA membership agreement. What we are seeing here is that
the corporate legal side agreed to something but the developers made
small errors along the way, and those errors were later copied by
other developers and spread widely. So the OFA has a basis for
requests of this nature.

For instance, a legal statement from Mellanox that all code they
contributed is available under the GPLv2 or *either* MIT or FreeBSD
license varient would allow immediately placing all Mellanox
copyrighted code under the single Default License. I expect this is
what Mellanox intended to do anyhow, the fact that ibverbs and all
their providers had an error in the COPYING file is simply
an unfortunate mistake.

These sorts of license issues are typical in historical code bases. I
would say we are in pretty good shape, from what I can tell absolutely
everything is unambiguously licensed under at least the GPLv2, or a
compatible license.

Almost everything is alternatively licensed under some kind of BSD
license. The notable exception is ipathverbs and rxe. It is also
unfortunate we have so many BSD variants.

Further, almost all C code is licensed under the dual GPLv2/OpenIB.org
(MIT) license. The kernel is similar, almost all C code is using the
MIT variant. Hence my desire to make that the license for new code in
the tree.

I would say this is a pretty good result.

My ultimate suggestion is that we push the non-default copyright into
the impacted files, eg add short licenses headers to the man pages,
etc, and then delete the extraneous COPYING files once every single
file has a correct license statement. From that point we can look at
switching individual files based on the above Legal process to the
Default License, or just leave them as is - a historical quirk.

It looks like a lot of work to do and it can be handled by anyone.
Can OPA handle this?

Openib.org doesn't exist.  Can we just drop that term from the files?

Maybe? I don't know, that is starting to go down the path that Leon
alluded to regarding getting legal advice.

That would be a different patch, IMHO.

Normally I'd say to avoid confusion it is good to stick with the
historical names, but in this case there are three things calling
themselves the openib.org bsd license, so I don't know :|

Yeah, because Leon doesn't understand (and doesn't want to understand)
this legal crap.

Re: [PATCH rdma-core] Improve global COPYING files

[Christoph Hellwig]

Hi Jason,

any chance you could simply follow the modern debian copyright file
format:


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

This format lists the copyright applying to each file while allowing
grouping for multiple files.  I think that's the best way to document
the licensing situation for a project that hasa few different licenses.

The catchall in this format also gives a good statement on what the
default for the repository should be.

I was thinking about doing that.. But choose not to for this first
draft.

1) I'd have to go and unwind on a file by file basis exactly what
   every licnese is. Right now I've just done a survey. There are many
   copyrightable files with no license text, and many potentially
   non-copyrightable files with no license text as well. All that
   needs to be figured out first.

   I would like to add at least short license headers to every file.
2) It seems to require listing the copyright owners for every file,
   this is a royal pain, IMHO. Many copyrightable files do not have
   copyright data, so it would have to be mined out of git. I have
   a script that does that someplace..

My thinking was to start small, document the survey results (and agree
my interpetation is sensible), then work on achiveing full copyright
headers, then use that to build the debian format.

I'd appreciate help, eg patches moving toward #1 and eliminating the
free COPYING files and unlicnesed items. I think it will take a bit to
get there, I still have a bit wack of patches to get applied on other
topics..

I just merged a pull request of yours, and that was the last outstanding
pull request in the github.  I still have to sort through patches on the
list that aren't in the github interface...but at least 20 or so of your
outstanding patches were taken in today.

Yep thanks, making progress, sent another 13 or so, I think there are
about 10 left now. Most of what remains in my preview tree needs a bit
more work I think.

The last big useful item is the directory rename/flatting patches, eg
to move libX/src/ to under providers/ and to flatten other directories.

Oh, and the packaging files..
