Download Firmware OpenWrt 19.07.7

A new update for version 19.07 of OpenWrt has been released. OpenWrt is an alternative open source firmware for a large number various routers and embedded devices. By means of the opkg package management system there is the possibility to determine for yourself what the router can and cannot do. Also on GoT there are several people actively working on it, see this topic. You can simply update the version with sysupgrade from the web interface. The main improvements made in this release are listed below.

Main changes from OpenWrt 19.07.6

Only the main changes are listed below. see changelog-19.07.7 for the full changelog.

Security fixes

• Security Advisory 2021-02-02-1 – netifd and odhcp6c routing loop on IPv6 point to point links (CVE-2021-22161)
• Security Advisory 2021-02-02-2 – wolfSSL heap buffer overflow in RsaPad_PSS (CVE-2020-36177)
• Various security fixes in packages

Note: security fixes for most packages can also be applied by upgrading only the affected packages on running devices, without the need for a full firmware upgrade. This can be done with opkg update; opkg upgrade the_package_name or through the LuCI web interface.

Nevertheless, we encourage all users to upgrade their devices to OpenWrt 19.07.7 or later versions whenever possible.

Major bug fixes

• Fix dnsmasq error messages such as failed to send packet: Network unreachable or failed to send packet: Address family not supported by protocol that could be filling up logs. This was a regression caused by the dnsmasq update in 19.07.6.
• Fix opkg so that it purges obsolete packages from its local cache. This fixes a long-standing issue in the ImageBuilder where a manual cleanup was needed before rebuilding: FS#2690

Device support

• Improve stability of mediatek Ethernet switch (affects many mt7621 devices): FS#2628
• Fix Wi-Fi band detection on some Broadcom-based devices
• Fix poor 2.4 GHz Wi-Fi performance on TP-Link Archer C50 v4 due to a missing EEPROM chip ID: FS#2781
• Make initramfs image usable out-of-the-box on Turris Omnia
• Use full flash size on Nucom R5010UN v2
• Fix support for TP-Link TL-WR810N v1 in ath79: FS#3522
• Remove broken factory image for TP-Link Archer C2 v1
• Fix unintended failsafe mode during boot on Netgear EX6150: FS#3590

Various fixes and improvements

• the ImageBuilder no longer requires compilers (gcc, g++) and libncurses-dev. This was partially implemented in 19.07.6 but one part was missing to make it actually work.
• Update to a new major version of ksmbd to fix several bugs. This breaks compatibility with previous versions of OpenWrt (19.07.0 to 19.07.6): it is no longer possible to install a working version of ksmbd-tools on previous versions of OpenWrt. Existing installations will keep working, but ksmbd-tools should not be upgraded with opkg. PR#14647

LuCI web interface

• Fix array sorting on Chrome: GH#4792
• Add nextdns.io and quad 101 providers to luci-app-https-dns-proxy package
• Update translations from website
• Several additional bug fixes and improvements

Core components

• Update Linux kernel from 4.14.215 to 4.14.221
• Update wolfssl from 4.5.0 to 4.6.0

Regressions

• kmod-fs-ksmbd has a dependency to the not existing package kmod-crypto-arc4. Installing kmod-fs-ksmbd returns this: * satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-fs-ksmbd: * kmod-crypto-arc4 * opkg_install_cmd: Cannot install package kmod-fs-ksmbd.
  • Run this to force the installation: GH#14771

    opkg install –force-depends kmod-fs-ksmbd

    to force the installation.

Known issues

• Transition to ath79: some devices that are supported in ar71xx are not yet supported in ath79: this is a community effort. Helping to port devices to ath79 to make them available in future releases is very welcome.
• device support: images for some device became too big to support a persistent overlay, causing such devices to lose configuration after a reboot. If you experience this problem, please report the affected device in the forum and consider downgrading to OpenWrt 18.06 or using the Image Builder to pack a smaller custom image
• device support: conversely, certain images for devices with small flash (4 MB) are no longer built for the release
