OpenWrt(fromopen wireless router) is an open-source project forembedded operating systemsbased onLinux,primarily used onembedded devicestoroutenetwork traffic. The main components are Linux,util-linux,musl,[4]andBusyBox.All components have been optimized to be small enough to fit into the limited storage and memory available in home routers.

OpenWrt is configured using acommand-line interface(ashshell) or a web interface (LuCI). There are about 8000 optionalsoftware packagesavailable for installation via theopkgpackage management system.

OpenWrt can run on various types of devices, includingCPErouters,residential gateways,smartphones,pocket computers(e.g.,Ben NanoNote). It is also possible to run OpenWrt onpersonal computersandlaptops.

History[edit]

The OpenWrt project was started in 2004 afterLinksyshad built thefirmwarefor theirWRT54G seriesof wireless routers with code licensed under theGNU General Public License.[5]Under the terms of that license, Linksys was required to make the source code of its modified version available under the same license,[6][7]which enabled independent developers to create derivative versions. Support was originally limited to the WRT54G series, but has since been expanded to include many other routers and devices from many different manufacturers.

Using this code as a base and later as a reference, developers created aLinux distributionthat offers many features not previously found in consumer-level routers. Early on some features required proprietary software. For example, prior to OpenWrt 8.09 (based on Linux 2.6.25 and theb43kernel module) WLAN for manyBroadcom-based routers could only be had via the proprietarywl.omodule (and which required Linux 2.4.x).

OpenWrt releases were historically named after cocktails, such asWhite Russian,Kamikaze,Backfire, Attitude Adjustment, Barrier Breaker and Chaos Calmer, and their recipes were included in themessage of the day (motd)displayed after logging in using thecommand-line interface.

In May 2016, OpenWrt was forked by a group of core OpenWrt contributors due to disagreements on internal process.[8]The fork was dubbedLinux Embedded Development Environment(LEDE). The schism was reconciled a year later.[9]Following the remerger, announced in January 2018,[10]the OpenWrt branding is preserved, with many of the LEDE processes and rules used. The LEDE project name was used for v17.01, with development versions of 18.01 branded OpenWrt, dropping the original cocktail based naming scheme.[11]

TheLinux Embedded Development Environment(LEDE) project was aforkof the OpenWrt project and shared many of the same goals.[46][47][48][49][50]It was created in May 2016 by a group of core OpenWrt contributors due to disagreements on OpenWrt internal processes.[47]The schism was nominally reconciled a year later in May 2017 pending approval of the LEDE developers.[51]The remerger preserves the OpenWrt branding, but uses many of the LEDE processes and rules. The remerge proposal vote was passed by LEDE developers in June 2017,[52]and formally announced in January 2018.[53]The merging process was completed before the OpenWrt 18.06 release.[54]

Features[edit]

OpenWrt features a writeableroot file system,enabling users to modify any file and easily install additional software. This is in contrast with other firmware based on read-only file systems which don't allow modifying installed software without rebuilding and flashing a complete firmware image. This is accomplished by overlaying a read-only compressedSquashFSfile system with a writeableJFFS2file system usingoverlayfs.[62][63]Additional software can be installed with theopkgpackage manager and the package repository contains approximately 8000 packages (by 2022).

LuCI

OpenWrt can be configured through either acommand-line interfaceor a web interface called LuCI. OpenWrt provides set of scripts called UCI (unified configuration interface) to unify and simplify configuration through the command-line interface.[64]Additional web interfaces, such asGargoyle,are also available.

OpenWrt provides regular bug fixes and security updates even for devices that are no longer supported by their manufacturers.

OpenWrt provides exhaustive possibilities to configure common network-related features, likeIPv4,IPv6,DNS,DHCP,routing,firewall,NAT,port forwardingandWPA.

Other features include:

Development[edit]

OpenWrt's development environment and build system, known together asOpenWrt Buildroot,are based on a heavily modifiedBuildrootsystem. OpenWrt Buildroot is a set ofMakefilesandpatchesthat automates the process of building a complete Linux-based OpenWrt system for an embedded device, by building and using an appropriatecross-compilationtoolchain.[67][68]

Embedded devices usually use a different processor than the one found in host computers used for building their OpenWrt system images, requiring a cross-compilation toolchain. Such a compilation toolchain runs on a host system but generates code for a targeted embedded device and its processor'sinstruction set architecture(ISA). For example, if a host system usesx86and a target system usesMIPS32,the regular compilation toolchain of the host runs on x86 and generates code for x86 architecture, while the cross-compilation toolchain runs on x86 and generates code for the MIPS32 architecture. OpenWrt Buildroot automates this whole process to work on the instruction set architectures of most embedded devices and host systems.[67][69]

OpenWrt Buildroot provides the following features:[67][69]

  • Makes it easy to port software across architectures
  • Uses kconfig (Linux kernelmenuconfig) for the configuration of all options
  • Provides an integrated cross-compiler toolchain (gcc,ld,uClibcetc.)
  • Provides an abstraction forautotools(automake,autoconf),CMakeandSCons
  • Handles standard OpenWrt image build workflow: downloading, patching, configuration, compilation and packaging
  • Provides a number of common fixes for known badly behaving packages

Besides building system images, OpenWrt development environment also provides a mechanism for simplified cross-platform building of OpenWrt software packages. Source code for each software package is required to provide a Makefile-like set of building instructions, and an optional set of patches for bug fixes or footprint optimizations.[70]

Hardware compatibility[edit]

OpenWrt runs many different routers and includes a table of compatible hardware on its website.[71]In its buyer's guide,[72]it notes that users recommend devices equipped with wireless chips from either Qualcomm'sAtheros,Ralink (nowMediaTek) or any vendor with open source drivers and specifications. It specifically avoidsBroadcomchipsets as the feature set is very limited due to having no open drivers. OpenWrt also recommends choosing a device with a minimum of 16 MB of flash and 128 MB of RAM, preferably higher amounts.[73]

Adoption[edit]

OpenWrt, especially its Buildroot build system, has been adopted as the structure for other efforts. For example

  • AltiWi"one-time-fee-only" replacement for Cloudtrax.
  • Bufferbloat.net (Cerowrt)
  • Freifunkand other mesh network communities
  • IETFIPv6 integration projects HIPnet and HomeNet are OpenWrt-based
  • prplOS, carrier-grade framework designed to powerISPsrouters and gateways made byPrpl Foundation
  • SIMET Box, developed byNIC.br,is OpenWrt-based[74]

Derivative projects[edit]

  • AREDNTheAmateur RadioEmergency Data Network uses a firmware based on OpenWrt:GitHub Project
  • CeroWrt– (2011—2014) project to resolve bufferbloat in home networking, support IPv6, integrate DNSSEC, for wired and wireless, to complement the debloat-testing kernel tree and provide a platform for real-world testing ofbufferbloatfixes.[75]The CeroWRT project is completely by 2014, when the finalized fixes were merged into OpenWRT. The "Bufferbloat project" behind CeroWRT went on to research new methods such asCAKE.[76]
  • Coova chilli – OpenWrt-based with focus on wireless hotspots, a fork of chillifire with focus on wireless hotspot management
