Highlights In OpenWrt 18.06.0
The OpenWrt community is proud to announce the first release of the OpenWrt 18.06 stable version series. It incorporates over 4000 commits since branching the previous LEDE 17.01 release and has been under development for well over a year.
With this release, the re-merged OpenWrt project attempts to define a baseline for future development based on the technological modernization and refined release processes done by the former LEDE project.
Highlights of this release since the previous LEDE 17.01 and OpenWrt Chaos Calmer 15.05 versions are:
Linux kernel updated to version either 4.9.111 or 4.14.52, depending on the architecture
Updated toolchain:
musl libc 1.1.19
uClibc-ng 1.0.30
glibc 2.26+
gcc 7.3.0
binutils 2.29.1
Updated Linux kernel:
Kernel 4.9.111 for ar7, ar71xx, arc770, at91, brcm2708, brcm63xx, ixp4xx, lantiq, layerscape, mpc85xx, orion, rb532 and uml
Kernel 4.14.52 for apm821xx, archs38, armvirt, ath25, bcm53xx, brcm47xx, cns3xxx, gemini, imx6, ipq40xx, ipq806x, kirkwood, malta, mediatek, mvebu, mxs, octeon, octeontx, omap, oxnas, pistachio, ramips, sunxi and x86
Backported network flow offloading support for targets using kernel 4.14
Network userland:
IPv6 related fixes in DHCPv6 client and servers
Support for user DHCPv6 client options in sent packets
DHCP forced renew support (RFC6704) in odhcpd
Firewall support for conntrack helper setup and better ipset integration
Introduced support for configuring GRE, GRE-TAP, VETH, VTI, VXLAN
CAKE v20180716 includes tc filter classification making ingress prioritisation easier. Cake & sqm-scripts updated representing state of the art mitigations for bufferbloat
Wireguard VPN v20180625 with MIPS optimisations and flow-offload compatibility
System userland:
Improvements in system upgrade procedure
Bugfixes in the process manager, system message bus, embedded webserver and the configuration management library
Platform and Driver Support
Dropped adm5120, adm8668, au1000, mcs814x, omap24xx, ppc40x, ppc44x, xburst and zynq targets
Added Spectre and Meltdown mitigations as well as microcode loading support to x86
Rebased oxnas target on top of upstream Kernel 4.14 support
Updates and new device support across all targets
Web interface:
New auto-rollback functionality to revert configuration changes when access to the router is lost
Better support for displaying virtual interfaces and low level configuration errors
Security improvements
Known issues:
Support for a hardware-bug workaround needed for devices having an AT8032 ethernet phy accidentally got dropped. Hence devices with that ethernet chip may experience connectivity issues. At least ubnt-loco-m-xw and most likely other single-port ubnt devices are affected. [fix merged, queued for 18.06.1]
Using ip4ip6 tunnel interface as a fallback interface accepting ip4-in-ip6 tunneled packets from any remote address doesn't work. [fix merged, queued for 18.06.1]
Support for PCIe on ox820 is broken, results in missing USB3 support on Shuttle KD20 [driver needs more work]
Images for some device became too big to support a persistent overlay, causing such models to lose configuration after a reboot. If you experience this problem, please report the affected device and consider downgrading to LEDE 17.01.5 or using the Image Builder to pack a smaller custom image
Some devices, such as the Netgear R6100, may lack 5GHz wireless AC support. Investigation is ongoing and a fix is expected for 18.06.1. Affected users shall downgrade to LEDE 17.01.5 for the time being and wait for the first service release.
Devices using the mt76 wireless driver may experience stability issues on 2.4GHz
The legacy at91 and legacy ath25 (formerly “ atheros ”) targets failed to build due to image size constraints and are not part of the release
A GUI bug prevents selecting and scrolling text in the system and kernel log pages. To solve, either upgrade “ luci-theme-bootstrap ” using opkg or switch to another theme. [fix merged, queued for 18.06.1]
With the release of OpenWrt 18.06, the old OpenWrt 15.05 release is marked end of life and will not get any support any more, not even for severe security problems. LEDE 17.01 will still get some security support for a limited time. We encourage everyone to upgrade to OpenWrt 18.06 to get the best support.
As always, a big thank you goes to all our active package maintainers, testers, documenters, and supporters.
Have fun!
