All server-side code (OSD, Monitor and so on) is licensed under the terms of |
|
|
|
Vitastor Network Public License 1.1 (VNPL 1.1), a copyleft license based on |
|
|
|
GNU GPLv3.0 with the additional "Network Interaction" clause which requires |
|
|
|
opensourcing all programs directly or indirectly interacting with Vitastor |
|
|
|
through a computer network and expressly designed to be used in conjunction |
|
|
|
with it ("Proxy Programs"). Proxy Programs may be made public not only under |
|
|
|
the terms of the same license, but also under the terms of any GPL-Compatible |
|
|
|
Free Software License, as listed by the Free Software Foundation. |
|
|
|
This is a stricter copyleft license than the Affero GPL. |
|
|
|
|
|
|
|
Please note that VNPL doesn't require you to open the code of proprietary |
|
|
|
software running inside a VM if it's not specially designed to be used with |
|
|
|
Vitastor. |
|
|
|
|
|
|
|
Basically, you can't use the software in a proprietary environment to provide |
|
|
|
its functionality to users without opensourcing all intermediary components |
|
|
|
standing between the user and Vitastor or purchasing a commercial license |
|
|
|
from the author 😀. |
|
|
|
|
|
|
|
Client libraries (cluster_client and so on) are dual-licensed under the same |
|
|
|
VNPL 1.1 and also GNU GPL 2.0 or later to allow for compatibility with GPLed |
|
|
|
software like QEMU and fio. |
|
|
|
|
|
|
|
You can find the full text of VNPL-1.1 in the file [VNPL-1.1.txt](VNPL-1.1.txt). |
|
|
|
GPL 2.0 is also included in this repository as [GPL-2.0.txt](GPL-2.0.txt). |
