[PATCH 0/2] Drop suggestions of alternative acceptable licenses

[PATCH 0/2] Drop suggestions of alternative acceptable licenses

[Leif Lindholm]

(Echoing https://bugzilla.tianocore.org/show_bug.cgi?id=2834:)
In the past, the TianoCore Contribution Agreement provided equal to what
the (+patent) gives us, but also for all the alternative licenses listed
under "Code Contributions". When the contribution agreement was dropped,
no conversation was had about this aspect.

Until this issue is resolved, only code licensed under edk2+patent should
be accepted into the project.

It is not obvious whether modifications to non-bsd+patent code that *was*
contributed under the TCA can still be accepted.

This set deletes the current version of license checking in PatchCheck.py
that was added in a4cfb842fca9. It also deletes all references to other
acceptable licenses (and public domain).

This gives us a clean slate to make informed decisions on what is and is
not acceptable for this project.

The statement that "Contributions using other licenses might be accepted,
but further review will be required." is intentionally retained.

[PATCH 1/2] Revert "BaseTools/PatchCheck.py: Add LicenseCheck"

[Leif Lindholm]

This reverts commit a4cfb842fca9693a330cb5435284c1ee8bfbbace.
This commit suggests inclusion of non-edk2+license content without
a contribution agreement is something the community has made a
decision on, which is incorrect.

The expression "non-edk2+license" is a typo.

I think you meant "non-BSD-2-Clause-Patent".

I'm OK with commit a4cfb842fca9 being reverted, as this solves the
practical problem of adding generated files.

Acked-by: Laszlo Ersek <lersek@redhat.com>

That said, I *still* don't grasp the more general problem you refer to.

Can we express it as follows (using commits 6b621f958123 and
6f21d772aa6b as reference):

(1) Content under OvmfPkg/Include/IndustryStandard/Xen was introduced
under the MIT license in commit 6b621f958123. That commit was marked with:

> License: This patch adds many files under the MIT licence.
> Contributed-under: TianoCore Contribution Agreement 1.0

and the header files also contained open-coded instances of the MIT
license. (These would later be replaced with SPDX identifiers in commit
6f21d772aa6b.)

As a result, these files effectively granted use and distribution rights
under the MIT license, *plus* a patent grant (per TCA).

(2) If we did the same today (that is, add new MIT-licensed files, but
no "Contributed-under: TCA" line on the commit message), then that would
grant use and distribution rights under the "MIT license", and *no*
patent grant.

Is this the issue you're thinking of?


So are we basically looking to replace (for example):

  SPDX-License-Identifier: MIT

with *something* like:

  SPDX-License-Identifier: MIT-Patent

? (Assuming the latter exists -- which it doesn't, at the moment?)

It doesn't.

For BSD3/BSD4, we can do what the BSD distros do and use (for example)
SPDX-License-Identifier: BSD-3-Clause AND BSD-2-Clause-Patent

It is not clear to me if (for example) "MIT AND BSD-2-Clause-Patent"
is a valid expression. But what about "public domain"? Do we figure
out a jurisdiction in which public domain content can clearly have
arbitrary licenses applied to it and ask someone there to relicense it
to something we can accept?

If we decide the explicit patent grant isn't important, why did we add
it in the first place? If we decide it is important, we need to
actively make a decision on whether we can ever sidestep it, and if so
under what circumstances. (e.g.: "we permit it for tools" - but then
the code generation aspect also needs to be covered)

Leif

Re: [edk2-devel] [PATCH 1/2] Revert "BaseTools/PatchCheck.py: Add LicenseCheck"

[Liming Gao]

Leif:
  Shenglei is working on new patch to add license checker as open CI plug-in (BZ 2833). This way allows to add the exception. So, the autogen file can be handled. Based on current statement, only BSD-2-Clause-Patent license will be allowed. Other license can be added as the exception case if necessary. With new license checker in open CI, I agree to revert this checker in BaseTools/PatchCheck.py.

Thanks

Correct.

It doesn't.

For BSD3/BSD4, we can do what the BSD distros do and use (for example)
SPDX-License-Identifier: BSD-3-Clause AND BSD-2-Clause-Patent

It is not clear to me if (for example) "MIT AND BSD-2-Clause-Patent"
is a valid expression. But what about "public domain"? Do we figure out a jurisdiction in which public domain content can clearly have arbitrary licenses applied to it and ask someone there to relicense it to something we can accept?

If we decide the explicit patent grant isn't important, why did we add it in the first place? If we decide it is important, we need to actively make a decision on whether we can ever sidestep it, and if so under what circumstances. (e.g.: "we permit it for tools" - but then the code generation aspect also needs to be covered)

Leif

[PATCH 2/2] ReadMe.rst: delete statements about other accepted licenses

[Leif Lindholm]

In the past, the TianoCore Contribution Agreement provided equal to what
the (+patent) gives us, but also for all the alternative licenses listed
under "Code Contributions". When the contribution agreement was dropped,
no conversation was had about this aspect.

Until this issue is resolved, only code licensed under edk2+patent should
be accepted into the project.

This addresses, but does not resolve,

*IF* the problem you describe is real (honestly I've never *understood*
the problem statement before), then I think this change reflects that.
So here's a conditional:

I defer to Mike on this though, as Mike drove

Some crucial words seem to be missing from the above paragraph:

- "the TianoCore Contribution Agreement provided [???] equal to" -- do
you mean "rights"?

- "what the [???] (+patent) gives us" -- do you mean "2-clause BSDL"?

Thanks
