Olliver Schinagl 3561015efd scripts: Kernel bumper script
For years, we have struggled and been frustrated at loosing history of
files in git, due to the 'copy + add' strategy. This could have been
prevented with a double-commit 'mv + add' trick.

On the mailing list [0] the discussion was started to put the
instructions in a wiki. Instead, it is much better to just script it and
put it in the repo.

Instead of doing mv + copy, which leads to two commits, but no history
on the copied files, it uses move, + copy and merge, which results in
three (merge) commits, but keeps the history of all files. As always
with renames, `--follow` will be needed.

The tool is trivial and works either in the OpenWrt git root directory,
or in the actual target directory.

Tested on the `realtek` and generic targets.

Note, that the tool does not do any of the labor needed after the move,
such as updating configs, dropping patches etc.

To make sure this script is easily found by any developer, who just
wants to do a kernel bump, the script is added here and not to
maintainer-tools repo as those scripts are a little bit more specialized.
Bumping a kernel is a trivial task that often regular developers do,
where most do not even know the existence of maintainer tools, are not
part of the main repo they'd clone, not part of the docker container
they'd use and so discoverability is probably much more important.

README.md

OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Download

Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.

If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.

An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:

Development

To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.7+ rsync subversion unzip which

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.

  • LuCI Web Interface: Modern and modular interface to control the device via a web browser.

  • OpenWrt Packages: Community repository of ported packages.

  • OpenWrt Routing: Packages specifically focused on (mesh) routing.

  • OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
