[B.A.T.M.A.N.] [PATCH 0/6] alfred: License cleanup

[Sven Eckelmann]

Hi,

the kernel community is currently trying to make the licensing status more
clear in each file. This is mostly done by adding SPDX license identifiers
and defining a set of rules how these license related information has to
be stored.

I've used this opportunity to also go through all files of alfred (for
example with FSFE's `reuse lint`) and to annotate the files according to
the "Linux licensing rules" and FSFE's REUSE practices.

There are two things which could be seen as controversial:

* change of batman_adv.h to the Linux preferred license
  (I am waiting for Acks in the batman-adv patchset)
* explicitly mark remaining files as licensed under the GPL-2.0

Kind regards,
	Sven

[B.A.T.M.A.N.] [PATCH 1/6] alfred: Rename LICENSE to Linux's LICENSES/preferred/GPL-2.0

[Sven Eckelmann]

The alfred project shares files with other projects hosted on open-mesh.org
and kernel.org. These other projects use the filename
LICENSES/preferred/GPL-2.0 for the GPL-2.0 license. It is therefore
required to also use the same name for the license file when these files
reference this in their license header.

The SPDX header was imported from Linux but the actual GPL-2.0 text was
downloaded from https://www.gnu.org/licenses/gpl-2.0.txt

[B.A.T.M.A.N.] [PATCH 2/6] alfred: Add License-Filename to GPL-2.0 files

[Sven Eckelmann]

The FSFE REUSE practices [1] recommend to add a "License-Filename" tag to
files which don't contain the complete license text. The GPL-2.0 files
usually only have a small notice at the beginning of the file. The longer
license is usually stored in a separate file and therefore should be
referenced accordingly.

[B.A.T.M.A.N.] [PATCH 4/6] alfred: Add SPDX license identifier above copyright header

[Sven Eckelmann]

The "Linux kernel licensing rules" require that each file has a SPDX
license identifier as first line (and sometimes as second line). Since
alfred shares source files with the Linux kernel, it is appropriate to use
the same identifier.

The FSFE REUSE practices [1] would also require the same tags but have no
restrictions on the placement in the source file. Using the "Linux kernel
licensing rules" is therefore also fulfilling the FSFE REUSE practices
requirements at the same time.

[B.A.T.M.A.N.] [PATCH 5/6] alfred: Mark remaining files as GPL-2.0

[Sven Eckelmann]

Some files were not explicitly marked with any license. It is therefore
assumed that these are licensed under the GPL-2.0. Make this unambiguous by
adding this information direct to the file using the SPDX license
identifier. The FSFE REUSE *.license annotation file is used for files
which don't allow comments.

[B.A.T.M.A.N.] [PATCH 6/6] alfred: Change batman_adv.h license to MIT

[Sven Eckelmann]

The ISC license is considered as not recommended in "Linux kernel licensing
rules". It should only be used for existing code or for importing code from
a different project with that license.

But the kernel still has the similar sounding MIT/Expat license under the
preferred licenses. Switching to this license for this relatively new file
should therefore allow batman-adv to better follow the new licensing rules.

Signed-off-by: Sven Eckelmann <sven@narfation.org>

Only apply this change after the change was applied in batman-adv.

Please check

* https://www.gnu.org/licenses/license-list.html
