Linux Kernel Enforcement Statement
----------------------------------
As developers of the Linux kernel, we have a keen interest in how our software
is used and how the license for our software is enforced. Compliance with the
reciprocal sharing obligations of GPL-2.0 is critical to the long-term
sustainability of our software and community.
Although there is a right to enforce the separate copyright interests in the
contributions made to our community, we share an interest in ensuring that
individual enforcement actions are conducted in a manner that benefits our
community and do not have an unintended negative impact on the health and
growth of our software ecosystem. In order to deter unhelpful enforcement
actions, we agree that it is in the best interests of our development
community to undertake the following commitment to users of the Linux kernel
on behalf of ourselves and any successors to our copyright interests:
Notwithstanding the termination provisions of the GPL-2.0, we agree that
it is in the best interests of our development community to adopt the
following provisions of GPL-3.0 as additional permissions under our
license with respect to any non-defensive assertion of rights under the
license.
However, if you cease all violation of this License, then your license
from a particular copyright holder is reinstated (a) provisionally,
unless and until the copyright holder explicitly and finally
terminates your license, and (b) permanently, if the copyright holder
fails to notify you of the violation by some reasonable means prior to
60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Our intent in providing these assurances is to encourage more use of the
software. We want companies and individuals to use, modify and distribute
this software. We want to work with users in an open and transparent way to
eliminate any uncertainty about our expectations regarding compliance or
enforcement that might limit adoption of our software. We view legal action
as a last resort, to be initiated only when other community efforts have
failed to resolve the problem.
Finally, once a non-compliance issue is resolved, we hope the user will feel
welcome to join us in our efforts on this project. Working together, we will
be stronger.
Except where noted below, we speak only for ourselves, and not for any company
we might work for today, have in the past, or will in the future.
