Adrian Schmutzler a9703db720 mvebu: fix sysupgrade experience for early DSA-adopters
Conceptually, the compat-version during sysupgrade is meant to
describe the config. Therefore, if somebody starts with a device on
19.07 and swconfig, and that person does a forceful upgrade into a
DSA-based firmware without wiping his/her config, then the local
compat-version should stay at 1.0 according to the config present
(and not get updated).

However, this poses a problem for those people that early-adopted
DSA in master, as they already have adjusted their config for DSA,
but it still is "1.0" as far as sysupgrade is concerned. This can
be healed by a simple

   uci set system.@system[0].compat_version="1.1"
   uci commit system

But this needs to be applied _after_ the upgrade (as the "old" fwtool
on the old installation does not know about compat_version) and it
requires access via SSH (i.e. no pure GUI solution is available for
this group of people, apart from wiping their config _again_ for
no technical reason). Despite, the situation will not become
obvious to those just upgrading via GUI, they will just have the
experience of a "broken upgrade".

This is a conflict which cannot be resolved by achieving both goals,
we have to decide to either keep the strict concept or improve the
situation for early adopters.

In this patch, we address the issue by providing a uci-defaults
script that will raise the compat_version for _all_ people upgrading
into a 1.1 image, no matter whether they have reset config or not.
The idea is to implement this as a _temporary_ solution, so early
adopters can upgrade into the new mechanism without issues, and
after a few weeks/months we could remove the uci-defaults script
again.

If we e.g. remove the script just before 20.xx.0-rc1, early adopters
should have moved on by then, and existing stable users would still
get the intended experience.

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!

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.

gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev

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.
