[tor-dev] license question



Hello,


I?m currently implementing transparent proxying for tor with Layered Service
Provider feature on windows. Microsoft provides a sample to demonstrate how
to implement an empty LSP (this is a lot of work, even to do nothing). This
sample is distributed under the license attached in this email. I have been
advised on #tor-dev to ask here about its compatibility with 3-clause BSD.

It seems compatible to me but the following restriction may be a problem in
an open source context:

"You may not [...] modify or distribute the source code of any Distributable
Code so that any part of it becomes subject to an Excluded License. An
Excluded License is one that requires, as a condition of use, modification
or distribution, that:
- the code be disclosed or distributed in source code form, or
- others have the right to modify it."

The wording "requires, as a condition of use, modification or distribution"
seems to allow to use the sample in tor, since there is no such requirement
in 3-clause BSD.

Does this seem right to you?


Cheers,
Frederic

9.      APPLICABLE LAW.

a.      United States.  If you acquired the software in the United States, Washington state law governs the interpretation of this agreement and applies to claims for breach of it, regardless of conflict of laws principles.  The laws of the state where you live govern all other claims, including claims under state consumer protection laws, unfair competition laws, and in tort.

11.  DISCLAIMER OF WARRANTY.   The software is licensed “as-is”.  You bear the risk of using it.  Microsoft gives no express warranties, guarantees or conditions.  You may have additional consumer rights under your local laws which this agreement cannot change.  To the extent permitted under your local laws, Microsoft excludes the implied warranties of merchantability, fitness for a particular purpose and non-infringement.

12.  LIMITATION ON AND EXCLUSION OF REMEDIES AND DAMAGES.  You can recover from Microsoft and its suppliers only direct damages up to U.S. $5.00. You cannot recover any other damages, including consequential, lost profits, special, indirect or incidental damages.  This limitation applies to:

·         anything related to the software, services, content (including code) on third party Internet sites, or third party programs, and

·         claims for breach of contract, breach of warranty, guarantee or condition, strict liability, negligence, or other tort to the extent permitted by applicable law.

It also applies even if Microsoft knew or should have known about the possibility of the damages. The above limitation or exclusion may not apply to you because your country may not allow the exclusion or limitation of incidental, consequential or other damages.

Elle s’applique également, même si Microsoft connaissait ou devrait connaître l’éventualité d’un tel dommage.  Si votre pays n’autorise pas l’exclusion ou la limitation de responsabilité pour les dommages indirects, accessoires ou de quelque nature que ce soit, il se peut que la limitation ou l’exclusion ci-dessus ne s’appliquera pas à votre égard.

EFFET JURIDIQUE.  Le présent contrat décrit certains droits juridiques. Vous pourriez avoir d’autres droits prévus par les lois de votre pays.  Le présent contrat ne modifie pas les droits que vous confèrent les lois de votre pays si celles‑ci ne le permettent pas.
