Highlights in OpenWrt 22.03.0

Firewall4 based on nftables

Firewall4 is used by default instead of firewall3 in the OpenWrt default images. Firewall4 uses nftables instead of iptables to configure the Linux netfilters.

Firewall4 uses the same UCI firewall configuration. Old firewall configurations should still work with firewall4, using nftables now. The extra option which allowed to add custom iptables commands does not work any more.

iptables is not included in the default images any more, it can be added with opkg or ImageBuilder if needed. iptables-nft, arptables-nft, ebtables-nft and xtables-nft provide the known command line interface from the old tools, but they will create nftables entries instead.

Many new devices added

OpenWrt 22.03 supports over 1550 devices. Support for over 160 new devices were added in addition to the device support by OpenWrt 21.02. OpenWrt 22.03 supports more than 10 devices capable of Wifi 6 (IEEE 802.11ax) using the MediaTek MT7915 wifi chip.

The qoriq target for the NXP QorIQ (PowerPC) was added in OpenWrt 22.03. The bmips target for the Boardcom MIPS BCM33xx, BCM63xx and BCM7xxx SoCs was added.

More targets converted to DSA

The following targets or boards were migrated from swconfig to DSA with OpenWrt 22.03 in addition to the systems already migrated with OpenWrt 21.02:

bcm53xx: All board using this target were converted to DSA lantiq: All boards using the xrx200 / vr9 SoC sunxi: Bananapi Lamobo R1 (only sunxi board with switch)

Dark mode in LuCI

The LuCI bootstrap design supports a dark mode. The default design activates dark mode depending on the browser settings. Change it manually at “System” → “System” → “Language and Style”.

Year 2038 problem handled

OpenWrt 22.03 uses musl 1.2.x, which changed the time_t type from 32 bit to 64 bit on 32 bit systems, on 64 bit system it was always 64 bit long. When a Unix time stamp is stored in a signed 32 bit integer it will overflow on 19 January 2038. With the change to 64 bit this will happen 292 billion years later. This is a change of the musl libc ABI and needs a recompilation of all user space applications linked against musl libc. For 64 bit systems this was done when the ABI was defined many years ago, the glibc ARC ABI already has a 64 bit time_t.

Upgrading to 22.03.0-rc6

Sysupgrade can be used to upgrade a device from 21.02 to 22.03, and configuration will be preserved in most cases.

There is no migration path for targets that switched from swconfig to DSA. In that case, sysupgrade will refuse to proceed with an appropriate error message:

Image version mismatch. image 1.1 device 1.0 Please wipe config during upgrade (force required) or reinstall. Config cannot be migrated from swconfig to DSA Image check failed

Known issues

• None

Final notes

As always, a big thank you goes to all our active package maintainers, testers, documenters, and supporters.

Have fun!
