[PATCH] samples: replace FSF address with web source in license notices

[PATCH] samples: replace FSF address with web source in license notices

[Martin Kepplinger]

A few years ago the FSF moved and "59 Temple Place" is wrong. Having this
still in our source files feels old and unmaintained.

Let's take the license statement serious and not confuse users.

As https://www.gnu.org/licenses/gpl-howto.html suggests, we replace the
postal address with "<http://www.gnu.org/licenses/>" in the samples
directory.

What would be best is to just put the SPDX single line at the top of the
files, and then remove this license "boilerplate" entirely.  I've
started to do that with some subsystems already (drivers/usb/ and
drivers/tty/ are almost finished, see Linus's tree for details), and
I've sent out a patch series for drivers/s390/ yesterday if you want to
see an example of how to do it.

Could you do that here instead of this patch as well?

thanks,

Is there consensus about this? I'm not a layer, but is this clear enough 
for
useres? And what holds against only adding the new SPDX tag line at the 
top?

Other than I don't like mixing // and /**/ comments, it indeed looks
quite clean. Is there consensus about the syntax too?

thanks

What do you mean by "adding a new" line?  That would change the license
of the file, so don't do that :)

And yes, a single SPDX line in the file is determined to be a valid
legal mark of the license of the file according to all of the lawyers I
have been working with from lots of different companies.  See the last
s390 patch series for one such example of that.

See the patch series from Thomas on lkml for the syntax format, the
"consensus" was driven by Linus :)

[PATCH] samples: replace outdated permission statement with SPDX identifiers

[Martin Kepplinger]

This replaces license permission statements that include a wrong postal
address of the FSF with only SPDX license identifiers; in the samples
directory.

Signed-off-by: Martin Kepplinger <martink@posteo.de>

I'll fold this in, in the thread here. I guess this change is what Greg
had in mind? Or would you prefer having including SPDX and removing
permission statement seperately?

thanks

I have been doing them in 2 steps, but only because the files I modified
were in different "chunks" (i.e. add missing SPDX identifiers to a bunch
of files in a directory, and then the second patch would remove the
license identifiers for all files in that directory).  As that type of
patch flow doesn't make sense here, I think what you did was just fine.

So I'll confess to being a little worried about removing the boilerplate:

	And it's important to notice that while adding a SPDX line should
	not really be controversial (as long as you get the license right,
	of course - Greg&co have the CSV files for everything, in case you
	want to check things you maintain), before removing the
	boiler-plate you really need to feel like you "own" the file.
	— Linus (https://lkml.org/lkml/2017/11/2/715)

Are we sure that we're not going to get in trouble with the people who do
"own" those files if we rip out the boilerplate?  It would be good to have
some clarity on when that can be done.

Thanks,

jon

Greg,

I assume you are well aware that I initially simply wanted to correct an
actual mistake in the permission statements with my proposed changed.

I asked whether you know about any consesus met before doing something
like removing people's permission statements. That's because the FSF's
"reuse" project pushing SPDX, for example says "Don't remove any license
texts", see https://reuse.software/practices/ and "Don’t remove existing
headers, but only add to them."

It may well be that that's not the all there's to it and that there's
other ways.

But Greg, people are listening to you. Please don't give advice in
directions that are not clearly correct for Linux. You know you could
have simply ack'd the initial mistake-fix in that case. It wouldn't have
hurt anybody.

just saying because it'd be nice to rely on things you say :)

thanks

Sigh, it wasn't my intent to get Greg in trouble.

Martin...  please don't blame Greg here.  What's going on (IMO) is that
you've stumbled into something that we have just now begun to figure
out.  We very much *want* to rip out all that boilerplate, but we don't
yet have a consensus on the proper way to do it.  We haven't really even
had the discussion yet.  You've just had the poor luck to wander in at
the wrong time and become part of that discussion.

I'll confess that, when I saw your first patch, it crossed my mind to
answer much like Greg did.  But Greg always gets there first :)

The files that you are touching mostly have listed copyright holders in
them.  Should you feel like putting a bit more energy into this, one
thing to do could be to copy them on a new posting of the patch and ask
for acks.  Assuming you get them, we should be able to clean up a bit of
cruft in a way that's clearly supported by the copyright holders.

Thanks,

jon

Alright, noone is in trouble already I hope. Maybe I was a little harsh;
sorry Greg. I know less about law than about programming which might
have made me a little nervous here; In the end I want things to work for
Linux.

Makes sense. Thanks for clearing this up a bit! So as fixing your "own"
files is easier, I'll do that first :)

I have discussed this with many lawyers, and as SPDX is acknowledged as
a valid way to specify the license that a file is released under,
removing the "boilerplate" text is just fine according to all of them.

As a backup to this, I have verification from at the legal department of
at least one very large corporate copyright holder in the kernel that
this is fine with them, and they are glad to see this happen, as now we
will not have 700+ different ways to say "released under the GPL v2" in
the tree.  You can see one of the patch series on lkml where I say I got
their approval as proof.

So yes, this should be fine, but of course, ask the copyright holder of
the file when doing this.  I have been cc:ing the owners of the files
when I do this work, and have gotten no objections so far when doing
this work.

If anyone does object to this change, that's ok too.  I'll be glad not
to merge the patch that does this.  Which is why I have been splitting
the add-spdx and remove-boilerplate patches apart as they are two
different actions.

And if anyone wants me to talk to their lawyers about this, I'm more
than willing to do so, as for some reason I end up being the one doing
this a lot these days...

Hope this helps explain things better,

Please see my response to Jon about this.  I am giving advice that I
have gotten from people I trust to wish to see Linux succeed in a
legally compliant way with all copyright and license laws.

I want to have people rely on it as well, if I'm ever saying anything
that seems contrary to what anyone feels is good for the long-term
success of Linux, please let me know.

Ok that's probably important. Even if not strictly necessary, at least
when I get acks from all copyright holder, I feel this is safe to do for
me or anybody.

Thanks. That's annoying work and I appreciate it.

Linus is simply wrong here. SPDX at first line of file looks extremely
ugly, and basically negates most of the SPDX advantages. I'm sure
Linus will accept replacing the license text with SPDX (so no // crap
at the first line of file), which should look way better, and is what
U-Boot does.
