NAK, for both the libxfs patch and the kernel one. I wrote the file and it has no copyright header because it conatians trivial, non-copyrightable code. I don't know why people think they can touch license information on files I've written without even asking me. Seems like this happened to various other files as well. Greg: why do you think you can add licensing information to other peoples files without even talking to them? On Mon, Nov 06, 2017 at 06:06:07PM -0800, Darrick J.

Ok, fine, I don't want to argue nuances, there's lots of exceptions to the rule for stuff like this, let's just say that "most" code is copyrightable and leave it at that :) And that's not what this thread is about, no copyrights got changed at all with this pull request. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Well if Christoph owns the copyright (if there is one) and he has stated he believes it is too trivial to copyright then it needs an SPDX tag that indicates the rightsholder has stated it's too trivial to copyright and (by estoppel) revoked any right they might have to pursue a claim. I'm sure there's a correct SPDX tag for that ;-) Alan -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

If Cristoph has revoked any right to pursue a claim, then he's also legally given up the right to complain if, say, Bradley Kuhn starting distributing a version with a GPLv3 permission statement --- or if Greg K-H adds a GPLv2 SPDX identifier. :-) - Ted > I'm sure there's a correct SPDX tag for that ;-) > > Alan -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Second Christoph really appreciates talking to him when trying to slap on licensing bits on his code. I'm not evil, but I'd really like to understand what you are doing and why, and I might be fairly agreeable if that makes sense. Doing batch annotations of code where you do not the know any of the history of is a receipt for a desaster if we want to use that information anywhere. So Greg, please explain WTF you are trying to do and talk to the people who wrote the code you are "annotating". -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I already described it in the pull request, and in this patch itself, and in this thread already, what is happening, why it was done, and how it was done. I don't know how everyone who was on the original email thread got dropped and the xfs mailing list added, that's just odd... > Doing batch annotations of code where you do not the know any of > the history of is a receipt for a desaster if we want to use that > information anywhere. But we did research the history as well as we could when touching 11k files at a single time. It's been months of research and work, as described in the patch. If we got something wrong, very sorry, not a problem, please, let's put the proper license on the file and all will be good. What file are you concerned about, and what license belongs on it? This patch only touched files without any license header, so again, by default that implied it was GPLv2. Again, no copyright was changed at all. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

We typically have not cared bout this, what has changed for us to want to actually go ahead and do all this work? What happened? It further states: By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. It says a bit about legally binding stuff, that's strong language, however its unclear to me about what it could mean for dual licensed stuff where the goal is for the GPL to apply say on Linux but another license outside of Linux. So what type of legally binding definition was being concocted here, how did such consensus get reached and why did we turn around and decide to embrace it all of a sudden whereas we had not done so before? If you had already described this please let me know, I really tried looking and could not find it on commit b24413180f5600 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license"), a pointer would help.

Many of us have cared about it for years, and nothing "changed" except the fact that Kate and Thomas and Philippe spent about 10 months doing the real work.

The implicit license of files in the kernel that did not have an explicit license in them is GPLv2, all this patch does is explicitly mark them with that license. It has nothing to do with dual licenses at all. However, follow on patches for some subsystems are adding the correct dual license SPDX identifiers for files that are dual licensed. See the patches in the USB git tree for examples of that in places, if you are curious about how that works with SPDX. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Christoph: I am not speaking for Greg but let me highlight some issues and benefits as I chipped in a bit to help: Some data points in the 4.14.rc7 kernel: - there are 64,742 distinct license statements ... in 114,597 blocks of text ... in 42,602 files - license statements represent 480,455 lines of text - licenses are worded in 1,015 different ways - there are about 85 distinct licenses, the bulk being the GPL NB: All of these tallies were computed with scancode-toolkit [1] License text lines represent about 14.7% of all source comments. (using a CLOC to count comment lines) From an engineering perspective this feels to me as pure madness, unless everyone in kernel land is in love with legalese! I like to think of it this way: Licensing is important but repetitive long boilerplate in patches and in every file is just a noisy distraction from the code substance. Imagine if the kernel had 500 versions of a printf() function? Maintainers would refactor the hell of it to use a few functions. Replacing the boilerplate with licensing ids is exactly the same: a sane refactoring to remove duplicated boilerplate. In the end and ideally there should be no more than one line of licensing info per file, so no more than 70Kish: so there are about 400K lines of boilerplate to remove. The benefits now and later: - no distraction with licensing boilerplate cr*p in patches and files - no guessing licensing needed when sending a patch - anyone can grep the kernel tree for licensing, no extra tool needed - Greg must feel really good about deleting so much things for once The downsides: - folks can no longer express their creativity in licensing texts like licensing thermal code under the "therms" of the GPL [2] - legalese lovers need to find another codebase to satisfy their addiction Note also that beside the kernel, U-Boot has adopted the same approach for quite a while, and in the application world the Eclipse Foundation, JavaScript NPMs and Rubygems are some examples that adopted SPDX license ids to simplify and clarify licensing documentation.

I see now Greg deletes things from files he maintains which is even worse, given that the kernel tree doesn't document anywhere what these tags actually mean. So he deletes a lot of license tags and replaces them with tags he puts a great significance on, but which aren't defined.

But for that we don't need a sneaky patch that doesn't talk to kernel contributors. For that we need to a) agree on which licensing schemes we accept for future contributions b) cleary document that policy in the kernel tree c) reject anything that doesn't matter the above policy by manual and/or automated review An automated tag scheme might help with b) and c) above if done properly.

They are under a licence that is at least as permissive as GPL v2. However they may be under a more permissive licence and as you are not the rightsholder you don't have the right to relicence them mroe restrictvely. For example I find a reference piece of code whose author says it is 'too trivial to copyright'. I (not the author0 place that code in the kernel. The licence on that code is still 'too trivial to copyright' (by estoppel). That's GPL 2 compliant but it is *NOT* GPL. As anyone can contribute third party code that is GPL compliant legitimately you can't assume any unmarked code is GPL, merely 'at least GPL'.

I don't know how everyone who was on the original email > thread got dropped and the xfs mailing list added, that's just odd... This thread is a result of regular efforts to keep the xfsprogs libxfs code roughly in-sync with the kernel libxfs code. That's how the xfs mailing is on cc on this thread. That said, it's pretty obvious from Christoph's reaction that nobody emailed Christoph (the original author of xfs_cksum.h) about the original change to the kernel source. Nobody emailed the XFS maintainers for an ack to the kernel change, and nobody cc'd the linux-xfs mailing list as a heads-up. Neither XFS maintainer were invited to the summit where this change was discussed. I always thought the rules in SubmittingPatches[1] existed to facilitate cooperation with Linux subprojects and I strongly protest your decision to ignore us. Had anyone involved us, I would have suggested fixing the whole XFS tree to use the shortened tag instead of each file containing its own mutations of the GPL, and our broader XFS community could have worked with you on this. --D [1] submitting-patches.rst, section 5: 5) Select the recipients for your patch --------------------------------------- You should always copy the appropriate subsystem maintainer(s) on any patch to code that they maintain; look through the MAINTAINERS file and the source code revision history to see who those maintainers are.

I'll point out here that this file is shared with a userspace package that has a mixed LGPL/GPL code base, so even if we disregard what Christoph says, this file could actually be LGPL (like fs/xfs/libxfs/xfs_fs.h) and not GPL. So from that perspective alone, your process on deciding what license tag should be used is flawed and these changes needed, at minimum, maintainer review. IMO, unannounced, unreviewed tree wide change via a back-door commits sent straight to Linus reek of an attempt to avoid review and oversight. And that is *completely unacceptible* when making claims about important details like licenses for *code you do not know anything about*. We have a documented process for a reason: to stop shit like this from happening. > No copyright was changed, nothing at all happened except we explicitly > list the license of the file, instead of it being "implicit" before. You keep saying "no copyright has changed", despite being given an explicit statement by the code author that this is *exactly what you have done*. Cheers, Dave.

When a file does not have a license, again, all lawyers I have worked with said it is implicitly GPLv2, so we did the best we knew how at the time. If we got a few files wrong, please fix them up, I hit 11k files at once here. And how an internal file is shared with userspace is, to be fair, completely strange, you have to agree :) > We have a documented process for a reason: to stop shit like this > from happening. > > > No copyright was changed, nothing at all happened except we explicitly > > list the license of the file, instead of it being "implicit" before. > > You keep saying "no copyright has changed", despite being given an > explicit statement by the code author that this is *exactly what you > have done*.

Great, I'll gladly send you a patchset to do this, what tree do you want me to base it against? Note, all this original patchset did was hit the 11k files in the tree with no license text in it at all. That required a tree-wide change to resolve everything at once.

The documentation of this process is lagging the patches, as usually happens, sorry about that. Thomas is working on a document to describe the process, and what a file should contain, based on the work he has been doing. This was discussed at the kernel summit, and sorry for it not getting out wider than that audience, things take time, which is why I was only touching my subsystems with the "general license cleanups" at the moment until his document was ready.

It is not an 'industry-wide accepted set of tags' (did you get a company discount on buzzwords). Yes, it it a scheme someone can up with (seems like an industry consortium that happens to employ you, what a coincidence), and from a quick look it even seems like a pretty reasonable scheme. But without backing it with an explanation of those tags in the tree, and explaining people how to use them and how they are relevant it is absolutely useless. And to come up with a scheme we need to have a broad discussion on what we are doing. > sorry for the confusion, it was not intended at all, but it what happens > in time with distributed developers, all working at different rates on > different parts of the tree. Sorry but I call bullshit on this. We have absolutely no problem working together if we try. You clearly did not even try to cooperate with anyone - the clear indicator is that no RFC was posted, no questions were asked but you just sent a pull requests right before the end of the merge window. -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

On the contrary if it was implicitly LGPL you've just exercised the right to make it GPL and messed it up for others.

Thomas and I originally did it first the way with the SPDX line in the big comment block. If you don't like the format, complain and convince him otherwise, you are not getting anywhere by responding to this old topic about it again. Having it be the first line of the file is good, it's obvious, and stands out, which is the point, you want it to, it's a license :) thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Hey, Linus. This // SPDX at the begining of file looks really ugly. Can we get something that looks less bad? And BTW I responded to this uglyness before, but you just tried to make me shut up, and then did not reply. Given what quality you normally expect from patch submitters, you are doing pretty poor job here. > Having it be the first line of the file is good, it's obvious, and > stands out, which is the point, you want it to, it's a license :) What is good about that? License is about the least interesting thing about the file. Point of SPDX conversion (see the mail I was replying to?) was to make license information _less_ intrusive, not more. Tools can find SPDX anywhere in the file for the people that really care. That's how it works in U-Boot, which people are using as example of reasonable SPDX conversion: /* * Copyright (c) 2012 The Chromium OS Authors.

If/when anyone /does/ get to SPDX'ing the xfs files that already have a comment blob at the top, this is my preferred format for doing that.
