kernel: update deprecated license information Update the deprecated license information from GPL-2.0 to GPL-2.0-only as written in the COPYING file of the linux source tree. Also add the 'COPYING' file to the PKG_LICENSE_FILES variable. Signed-off-by: Florian Eckert <fe@dev.tdt.de> (cherry picked from commit 879826154fd3e5ec353117a9c00cecf5e38c4a16) Link: https://github.com/openwrt/openwrt/pull/15918 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> 2024-03-21 11:55:01 +00:00			`PKG_LICENSE:=GPL-2.0-only`

licensing: Add licensing metadata to many packages Two new variables are introduces to many packages, namely PKG_LICENSE and PKG_LICENSE_FILES - there may be more than one license applied to packages, and these are listed in the PKG_LICENSE variable and separated by spaces. All relevant license files are also added to the PKG_LICENSE_FILES variable, also space separated. The licensing metadata is put into the bin/<platform>/packages/Packages file for later parsing. A script for that is on it's way! SVN-Revision: 33861 2012-10-19 15:34:28 +00:00

build: introduce $(MKHASH) Before this commit, it was assumed that mkhash is in the PATH. While this was fine for the normal build workflow, this led to some issues if make TOPDIR="$(pwd)" -C "$pkgdir" compile was called manually. In most of the cases, I just saw warnings like this: make: Entering directory '/home/.../package/gluon-status-page' bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found [...] While these were only warnings and the package still compiled sucessfully, I also observed that some package even fail to build because of this. After applying this commit, the variable $(MKHASH) is introduced. This variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the correct path.

include: calculate md5sum over sorted kernel config symbol list and incorperate it into the kernel metapackage version, make kmods depend on this specific version. The aim of this change is to invalidate kmods which are built against a different kernel config on the opkg metadata level. Manual copying and insmod of custom *.ko files, e.g. for development purpose, is still possible.
