[PATCH 0/8] SPDX conversion for cryptographic algorithms

[PATCH 0/8] SPDX conversion for cryptographic algorithms

[Bagas Sanjaya]

I prompted to create this series when reviewing trivial,
checkpatch-fixing patches from Franziska Naepelt [1]. When
reviewing crypto ones and looking on SPDX changes, I felt that
these could be better sent as separate patch series covering
whole crypto/ directory instead. So here is the series and
happy reviewing!

This is at least the fourth or fifth time (I'm losing track) where you
have incorrectly assumed a particular non-GPL license text matches a
particular SPDX identifier without (apparently) checking.

Bagas, I urge that you learn more about the nature of SPDX identifiers
before submitting any further patches at least involving replacement
of non-GPL notices with SPDX identifiers. For this unprecedented
license notice replacement initiative to have any legitimacy it must
attempt to apply SPDX identifiers correctly.

This is not BSD-3-Clause as defined by SPDX. It may be a match to
`Brian-Gladman-3-Clause` but I haven't checked closely.

The BSD portion of this license notice is not a match to BSD-3-Clause
(see my comment on another patch which I think had the same license
text).

At the time, I guessed that boilerplate wording have the same meaning as
the actual BSD 3-Clause license.

(And no wonder why this file missed previous SPDX batches).

tglx, I'm adding you to Cc:. Please have a look on this (and following
below) BSD wording variants.

The first clause also addes disclaimer perseverance as in the second;
and the third clause is worded differently (but same meaning).

See my above reply.

Stephan (original author), was your intention to license these files
under BSD 3-Clause?

Thanks for reviewing.

What exactly does 'checking' entail here? There is no guidance in
Documentation/process/license-rules.rst on how to perform this
comparison.

Also, checkpatch now complains about missing SPDX identifiers, which
is what triggered this effort. Should it stop doing that?

Since we're in language pedantic mode: it must do more than attempt,
it must apply them correctly, period.

Arguably, this is an 'attempt to apply SPDX identifiers correctly' on
Bagas's part, which apparently falls short (and I may be guilty of the
same for some arch crypto code)

So what is the ambition here: do we just leave the ambiguous ones as-is?

I recommend yes, leave them as-is until the legal people who actually
care about having SPDX lines in all of the files take the time to do the
work to resolve these issues.

Remember, they are the ones asking for it, no need for us to do their
work for them :)

[PATCH 2/8] crypto: fcrypt: Replace dual BSD 3-Clause/GPL 2.0+ boilerplate with SPDX identifier

[Bagas Sanjaya]

fcrypt implementation (crypto/fcrypt.c) have license boilerplate
for GPL 2.0+ (as implemented in the kernel) and BSD 3-Clause
(from original Royal Institute of Technology code). Replace the
boilerplate text with corresponding SPDX license tag. As there
is no wording that allows using either license alternatively,
use AND operator.

The non-GPL portion of this notice does not match BSD-3-Clause as
currently defined by SPDX (see:
https://github.com/spdx/license-list-XML/blob/main/src/BSD-3-Clause.xml).
This is at least the third time in your recent patches that you have
assumed that a non-GPL license matches a particular SPDX identifier
without (apparently) checking.

That's assuming it's appropriate to represent this as a dual license
and omit the 'ALTERNATIVELY' parenthetical. I'm not sure how I feel
about that.

I missed the point of first clause of this BSD boilerplate, for which
I had to not delete the boilerplate. I can keep the SPDX tag if Stephan
(original author) or at least Greg agree with this BSD wording variant.

Do you mean the SPDX tag should have been with AND instead?

Thanks for reviewing.

[PATCH 8/8] crypto: cts: Convert MIT boilerplate to corresponding SPDX license identifier

[Bagas Sanjaya]

License boilerplate in CTS mode implementation (crypto/cts.c) looks like
MIT license with advertising clause. Replace it with correspondig
SPDX tag.

This is not the MIT license (as defined by SPDX) - there may not be an
SPDX identifier covering this license text.

This is at least the second time in your recent patches where you have
assumed that a non-GPL license corresponds to a particular SPDX
identifier without (apparently) checking.

I was thought of interpolating license tags (heuristic matching) in
cases like this. In this case, the UoMi license was adapted from
(and roughly resembled) MIT (hence I thought of MIT variant).

Greg, is Richard's comment right? If so, I'll drop this patch.

Thanks!

Nope, licenses don't always work that way, sorry.

Yes it is, please ask for all of these to not be applied.

There's a reason that we didn't do all of these in the first big sweep
of the kernel tree, as you are finding out :(

Did you mean this whole series? Other patches have not been reviewed
yet. Maybe Herbert can apply these rest of patches if there is
no objection.

Based on the review of these, I would drop them all until you can get a
review from someone with lots of license experience to add their
reviewed-by to them.

Heh.

Richard is the only person on thread who is a Lawyer with a Wikipedia
page.  https://en.wikipedia.org/wiki/Richard_Fontana Let's just assume
everything he says is 100% correct.
