Kevin Darbyshire-Bryant d7f378796f dnsmasq: Support nftables nftsets
Add build option for nftables sets. By default disable iptables ipset
support.  By default enable nftable nftset support since this is what
fw4 uses.

dnsmasq: nftset: serve from ipset config

Use existing ipset configs as source for nftsets to be compatible with
existing configs. As the OS can either have iptables XOR nftables
support, it's fine to provide both to dnsmasq. dnsmasq will silently
fail for the present one. Depending on the dnsmasq compile time options,
the ipsets or nftsets option will not be added to the dnsmasq config
file.

dnsmasq will try to add the IP addresses to all sets, regardless of the
IP version defined for the set. Adding an IPv6 to an IPv4 set and vice
versa will silently fail.

dnsmasq: support populating nftsets in addition to ipsets

Tell dnsmasq to populate nftsets instead of ipsets, if firewall4 is present in
the system. Keep the same configuration syntax in /etc/config/dhcp, for
compatibility purposes.

Huge thanks to Jo-Philipp Wich for basically writing the function.

dnsmasq: obtain nftset ip family from nft

Unfortunately dnsmasq nft is noisy if an attempt to add a mismatched ip address
family to an nft set is made.

Heuristic to guess which ip family a nft set might belong by inferring
from the set name.

In order of preference:

If setname ends with standalone '4' or '6' use that, else
if setname has '4' or '6' delimited by '-' or '_' use that (eg
foo-4-bar) else
If setname begins with '4' or '6' standalone use that.

By standalone I mean not as part of a larger number eg. 24

If the above fails then use the existing nft set query mechanism and if
that fails, well you're stuffed!

With-thanks-to: Jo-Philipp Wich <jo@mein.io> who improved my regexp
knowledge.

dnsmasq: specify firewall table for nftset

Permit ipsets to specify an nftables table for the set.  New config
parameter is 'table'.  If not specified the default of 'fw4' is used.

config ipset
	list name 'BK_4,BK_6'
	option table 'dscpclassify'
	option table_family 'ip'
	option family '4'
	list domain 'ms-acdc.office.com'
	list domain 'windowsupdate.com'
	list domain 'update.microsoft.com'
	list domain 'graph.microsoft.com'
	list domain '1drv.ms'
	list domain '1drv.com'

The table family can also be specified, usually 'ip' or 'ip6' else the
default 'inet' capable of both ipv4 & ipv6 is used.

If the table family is not specified then finally a family option is
available to specify either '4' or '6' for ipv4 or ipv6 respectively.

This is all in addition to the existing heuristic that will look in the
nftset name for an ip family clue, or in total desperation, query the
value from the nftset itself.

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 python3.6+ 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.

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).
