Do kernel modules have to be GPL?
Some would hold that all kernel modules are derived works of the kernel, so have to be GPLed regardless of header inclusion. Alternatively your closed module derives from the GPL module, and the GPL module derives from the kernel, so the closed module has to also be GPL.
Are BSD and GPL compatible?
This is the original BSD license, modified by removal of the advertising clause. It is a lax, permissive non-copyleft free software license, compatible with the GNU GPL. This license is sometimes referred to as the 3-clause BSD license.
Can I stop others from using my program under terms of GPL?
Both versions of the GPL have an exception to their copyleft, commonly called the system library exception. But if you want to use parts of other GPL-covered programs by other authors in your code, you cannot authorize the exception for them. You have to get the approval of the copyright holders of those programs.
How does gplv2 license work?
The GPL is a free software license, and therefore it permits people to use and even redistribute the software without being required to pay anyone a fee for doing so. You can charge people a fee to get a copy from you. You can’t require people to pay you when they get a copy from someone else.
Is Linux a GPL?
The Linux Kernel is provided under the terms of the GNU General Public License version 2 only (GPL-2.0), as published by the Free Software Foundation, and provided in the COPYING file.
Which license is released Linux kernel?
the GNU General Public License version 2
Linux as a whole is released under the GNU General Public License version 2 only (GPL-2.0-only) with an explicit syscall exception (Linux-syscall-note), but it also contains several files under other compatible licenses.
What is the difference between GPLV2 and GPLV3?
GPLV3 is longer compared to the GPLV2 since it almost tried to cover the same issues with the former license. 3. GPLV3 has more clarity on patent licenses, mostly on the wording of the license as it cannot be interpreted as “too broad.” It also applies to the protection of the patents unlike the GPLV2.
Is CDDL compatible with Apache?
In addition to that, both Apache 2.0 and BSD are considered compatible with the GNU GPL, unlike CDDL. However, the CDDL is compatible with both the Apache and the BSD licenses.
Why is GPL bad?
Many consider the GPL a “business-unfriendly” license because of its so-called viral nature: All software derived from GPL-licensed code must in turn be licensed under the GPL. If the GPL doesn’t work for you, you can purchase the software under an alternative commercial license.
Under which version of the GPL is the Linux kernel distributed?
GPLv2
Developers can omit it when licensing their software; the Linux kernel, for instance, is licensed under GPLv2 without the “any later version” clause.
How are [L]GPL licenses with the ‘or later’ option constructed?
License identifiers for licenses like [L]GPL with the ‘or later’ option are constructed by using a “+” for indicating the ‘or later’ option.: WITH should be used when there is a modifier to a license needed. For example, the linux kernel UAPI files use the expression: Other examples using WITH exceptions found in the kernel are:
Is the mpl-1 1 compatible with GPL2?
The MPL-1.1 is not GPL2 compatible. It may only be used for dual-licensed files where the other license is GPL2 compatible. If you end up using this it MUST be used together with a GPL2 compatible license using “OR”.
What license information is required for loadloadable kernel modules?
Loadable kernel modules also require a MODULE_LICENSE () tag. This tag is neither a replacement for proper source code license information (SPDX-License-Identifier) nor in any way relevant for expressing or determining the exact license under which the source code of the module is provided.
What is the license for modulemodule?
Module is licensed under GPL version 2. This does not express any distinction between GPL-2.0-only or GPL-2.0-or-later. The exact license information can only be determined via the license information in the corresponding source files. Same as “GPL”. It exists for historic reasons.
