 -----------------------------------------------------

The OpenWrt community is proud to announce the second service release of OpenWrt 19.07. It focuses on security and device support. It notably fixes a security issue in ppp and improves support for migrating devices from ar71xx to ath79.

About OpenWrt

The OpenWrt Project is a Linux operating system targeting embedded devices. It is a complete replacement for the vendor-supplied firmware of a wide range of wireless routers and non-network devices. See the Table of Hardware for supported devices. For more information about OpenWrt project organization, see the About OpenWrt pages.

Main changes from OpenWrt 19.07.1

Only the main changes are listed below. See changelog-19.07.2 for the full changelog.

Security fixes

Bug fixes and improvements

Device support

  • Fix ar71xx - ath79 sysupgrade for some devices: fritz300e
  • Add ar71xx - ath79 migration for wireless configuration of all ar93xx/qca95xx devices
  • Add support for more devices in ath79: Ubiquiti Nanostation Loco M (XM & XW), Picostation M (XM)
  • Add support for Luxul ABR-4500 and XBR-4500
  • Fix CPU performance issues on ipq806x
  • Re-enable images for D-Link DIR-645
  • Various fixes and improvements for several devices: TP-Link TL-MR3020 v3, TL-WA801ND v5, TL-WR841N/ND v8, TL-WR842N v2, WDR3600/WDR4300, Mikrotik RB912UAG-5HPnD r2, Netis WF-2881

LuCI web interface

  • uhttpd: improve reliability of HTTPS requests under heavy load (there was a deadlock leading to timeouts). There may remain residual issues.
  • Fix support for the optional nginx integration
  • Update translations from weblate

Core components

  • Update Linux kernel from 4.14.167 to 4.14.171
  • Update mac80211 for brcm to latest 5.6 backports

Regressions

  • libubox regression: procd may fail to start or restart some services due to a regression in libubox (thread)

Known issues

  • Transition to ath79: several 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: unstable Ethernet link with atheros switch on some ath79 devices (such as TL-WR841N): FS#2216, FS#2730
  • LuCI web interface: some optional GUI packages crash with an error about missing “cbi.lua”, install the luci-compat package to fix these

Upgrading to OpenWrt 19.07.2

Upgrading from previous OpenWrt 19.07 versions is straightforward thanks to the sysupgrade utility: sysupgrade from web interface or sysupgrade from command-line.

An upgrade from OpenWrt 18.06 to OpenWrt 19.07 is supported in many cases, including preserving configuration. A configuration backup is advised nonetheless when upgrading from OpenWrt 18.06.

Highlights in OpenWrt 19.07

With this release, the OpenWrt project brings all supported targets back to a single common kernel version and further refines and broadens existing device support. It also introduces a new ath79 target and brings support for WPA3.

Target transition from ar71xx to ath79

This release provides initial support for the new ath79 target, the future device tree based successor of the popular ar71xx target. For 19.07, both targets are still built, but it is recommended to switch to the ath79 target whenever possible: future releases of OpenWrt will drop support for the ar71xx target. See the ath79 technical reference for rationale about the transition.

To perform the upgrade, please follow the instructions from Upgrading from ar71xx to ath79. Functionality for a given device should be equivalent between the two targets: if this is not the case, please report the issue and revert back to ar71xx if needed.

WPA3 support

The 19.07 release brings initial support for WPA3. However, WPA3 is not enabled by default and requires installing specific packages: to run WPA3 as an access point, hostapd-openssl is needed. For use as a Wi-Fi station, you need either wpa-supplicant-openssl (station support only) or wpad-openssl (AP + station). Due to their large size, these packages are not installed by default, and it is impossible to install them on devices with less than 8MB flash.

It should also be noted that many existing client devices will never support WPA3, and that there are client devices that support WPA2 but cannot connect to an AP configured with WPA2+WPA3 mixed mode. Please only file bugs if you are sure the problem is not client related.

To configure your device as a WPA3 access point, see wpa_modes

Client-side rendering of the LuCI web interface

The new version of LuCI, the integrated web interface for OpenWrt, implements client-side rendering of views. This improves performance by offloading some work that was done on the device (Lua code) to the client browser (Javascript code)

The LuCI ecosystem is large, and not all LuCI apps have been adapted to this change, which may result in crashes involving cbi.lua. In that case, install the luci-compat package.

If LuCI is loading slowly, consider installing uhttpd-mod-ubus, close and reopen the browser tab to start a new LuCI session.

With this step, Lua usage in LuCI is reduced and LuCI effectively comes closer to the goals of the experimental LuCI2 without having to rewrite everything from scratch.
