Etienne Champetier b0bd6599e8 iptables: rework ip(6)tables-nft dependencies 
according to iptables-nft man page,
"These tools use the libxtables framework extensions and hook to the nf_tables
kernel subsystem using the nft_compat module."

This means that to work, iptables-nft needs the same modules as
iptables legacy except the ip(6)table-{filter,mangle,nat,raw}
ip_tables, ip6tables.
When those modules are loaded iptables-nft-save output contains
"# Warning: iptables-legacy tables present, use iptables-legacy-save to see them"
But as long as it's empty it should not be a problem.

To have nft properly display the rules created by ip(6)tables-nft we need
all iptables targets and matches to be built as extension and not built-in
(/usr/lib/iptables/libip(6)t_*.so)

When switching a package to iptables-nft, you need to keep the
iptables-mod-* dependencies

This patch does minimal changes:
- remove the direct iptables-nft -> iptables dependency
- and more important add nft-compat dependency

The rule
iptables-nft -A OUTPUT -d 8.8.8.8 -m comment --comment "aaa" -j REJECT
becomes
table ip filter {
	chain OUTPUT {
		type filter hook output priority filter; policy accept;
		ip daddr 8.8.8.8 # xt_comment counter packets 0 bytes 0 # xt_REJECT
	}
}

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!

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 python3.6+ 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.

Related Repositories

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).
