Hi Liming,
Yes, the license is not a problem.
My concern is that third party code, regardless of license,
contributed while the TianoCore Contribution agreement was used was
covered by the clause:
* Contributor grants a license (with the right to sublicense) under
claims of Contributor's patents that Contributor can license that
are infringed by the Contribution (as delivered by Contributor) to
make, use, distribute, sell, offer for sale, and import the
Contribution and derivative works thereof solely to the minimum
extent necessary for licensee to exercise the granted copyright
license; this patent license applies solely to those portions of
the Contribution that are unmodified. No hardware per se is
licensed.
whereas code that is contributed now under a bsd+patent license is
covered by:
---
Subject to the terms and conditions of this license, each copyright holder
and contributor hereby grants to those receiving rights under this license
a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except for failure to satisfy the conditions of this license) patent
license to make, have made, use, offer to sell, sell, import, and otherwise
transfer this software, where such license applies only to those patent
claims, already acquired or hereafter acquired, licensable by such copyright
holder or contributor that are necessarily infringed by:
(a) their Contribution(s) (the licensed copyrights of copyright holders and
non-copyrightable additions of contributors, in source or binary form)
alone; or
(b) combination of their Contribution(s) with the work of authorship to
which such Contribution(s) was added by such copyright holder or
contributor, if, at the time the Contribution is added, such addition
causes such combination to be necessarily infringed. The patent license
shall not apply to any other combinations which include the
Contribution.
Except as expressly stated above, no rights or licenses from any copyright
holder or contributor is granted under this license, whether expressly, by
implication, estoppel or otherwise.
---
Non-bsd+patent contributions being brought into the tree after we
dropped the contribution agreement is not covered by any such explicit
patent grants.
And I think we need to have an official view on that - whether that
view is
- that's not a problem
- that can be problematic, but we can decide on a case by case basis,
and may request {extra steps} as part of the contribution
- that is not acceptable
And I think that view should be encoded in Readme.md, next to the list
of licenses we are willing to consider for inclusion.
Best Regards,
Leif
