5* Copyright policy
|
||||
-_-_-_-_-_-_-_-_-_-_
|
||||
|
||||
The developers of libssh have a policy of asking for contributions to be made
|
||||
under the personal copyright of the contributor, instead of a corporate
|
||||
copyright.
|
||||
libssh is a project with distributed copyright ownership, which means we prefer
|
||||
the copyright on parts of libssh to be held by individuals rather than
|
||||
corporations if possible. There are historical legal reasons for this, but one
|
||||
of the best ways to explain it is that it’s much easier to work with
|
||||
individuals who have ownership than corporate legal departments if we ever need
|
||||
to make reasonable compromises with people using and working with libssh.
|
||||
|
||||
There are some reasons for the establishment of this policy:
|
||||
We track the ownership of every part of libssh via git, our source code control
|
||||
system, so we know the provenance of every piece of code that is committed to
|
||||
libssh.
|
||||
|
||||
* Individual copyrights make copyright registration in the US a simpler
|
||||
process.
|
||||
* If libssh is copyrighted by individuals rather than corporations,
|
||||
decisions regarding enforcement and protection of copyright will, more
|
||||
likely, be made in the interests of the project, and not in the interests
|
||||
of any corporation’s shareholders.
|
||||
* If we ever need to relicense a portion of the code contacting individuals
|
||||
for permission to do so is much easier than contacting a company.
|
||||
So if possible, if you’re doing libssh changes on behalf of a company who
|
||||
normally owns all the work you do please get them to assign personal copyright
|
||||
ownership of your changes to you as an individual, that makes things very easy
|
||||
for us to work with and avoids bringing corporate legal departments into the
|
||||
picture.
|
||||
|
||||
If you can’t do this we can still accept patches from you owned by your
|
||||
employer under a standard employment contract with corporate copyright
|
||||
ownership. It just requires a simple set-up process first.
|
||||
|
||||
We use a process very similar to the way things are done in the Linux Kernel
|
||||
community, so it should be very easy to get a sign off from your corporate
|
||||
legal department. The only changes we’ve made are to accommodate the license we
|
||||
use, which is LGPLv2 (or later) whereas the Linux kernel uses GPLv2.
|
||||
|
||||
The process is called signing.
|
||||
|
||||
How to sign your work
|
||||
----------------------
|
||||
|
||||
Once you have permission to contribute to libssh from your employer, simply
|
||||
email a copy of the following text from your corporate email address to:
|
||||
|
||||
contributing@libssh.org
|

libssh Developer's Certificate of Origin. Version 1.0

|
||||
By making a contribution to this project, I certify that:
|
||||
|
||||
(a) The contribution was created in whole or in part by me and I
|
||||
have the right to submit it under the appropriate
|
||||
version of the GNU General Public License; or
|
||||
|
||||
(b) The contribution is based upon previous work that, to the best of
|
||||
my knowledge, is covered under an appropriate open source license
|
||||
and I have the right under that license to submit that work with
|
||||
modifications, whether created in whole or in part by me, under
|
||||
the GNU General Public License, in the appropriate version; or
|
||||
|
||||
(c) The contribution was provided directly to me by some other
|
||||
person who certified (a) or (b) and I have not modified it.
|
||||
|
||||
(d) I understand and agree that this project and the contribution are
|
||||
public and that a record of the contribution (including all
|
||||
metadata and personal information I submit with it, including my
|
||||
sign-off) is maintained indefinitely and may be redistributed
|
||||
consistent with the libssh Team's policies and the requirements of
|
||||
the GNU GPL where they are relevant.
|
||||
|
||||
(e) I am granting this work to this project under the terms of the
|
||||
GNU Lesser General Public License as published by the
|
||||
Free Software Foundation; either version 2.1 of
|
||||
the License, or (at the option of the project) any later version.

|
||||
--------------------------------------------------------------------------
|
||||
|
||||
We will maintain a copy of that email as a record that you have the rights to
|
||||
contribute code to libssh under the required licenses whilst working for the
|
||||
company where the email came from.
|
||||
|
||||
Then when sending in a patch via the normal mechanisms described above, add a
|
||||
line that states:
|
||||
|
||||
|
||||
Signed-off-by: Random J Developer <random@developer.example.org>
|
||||
|
||||
|
||||
using your real name and the email address you sent the original email you used
|
||||
to send the libssh Developer’s Certificate of Origin to us (sorry, no
|
||||
pseudonyms or anonymous contributions.)
|
||||
|
||||
That’s it! Such code can then quite happily contain changes that have copyright
|
||||
messages such as:
|
||||
|
||||
|
||||
(c) Example Corporation.
|
||||
|
||||
|
||||
and can be merged into the libssh codebase in the same way as patches from any
|
||||
other individual. You don’t need to send in a copy of the libssh Developer’s
|
||||
Certificate of Origin for each patch, or inside each patch. Just the sign-off
|
||||
message is all that is required once we’ve received the initial email.
|
||||
|
||||
Have fun and happy libssh hacking!

We will maintain a copy of that email as a record that you have the rights to

contribute code to libssh under the required licenses whilst working for the

company where the email came from.
|

|

Then when sending in a patch via the normal mechanisms described above, add a

line that states:

|

to send the libssh Developer’s Certificate of Origin to us (sorry, no
|

pseudonyms or anonymous contributions.)
|

|
||||
That’s it! Such code can then quite happily contain changes that have copyright
|
||||
messages such as:
|
||||
|
||||
@verbatim
|
||||
(c) Example Corporation.
|
||||
@endverbatim
|
||||
|
||||
and can be merged into the libssh codebase in the same way as patches from any
|
||||
other individual. You don’t need to send in a copy of the libssh Developer’s
|
||||
Certificate of Origin for each patch, or inside each patch. Just the sign-off
|
||||
message is all that is required once we’ve received the initial email.
|

Have fun and happy libssh hacking!
