Openwrt “Chaos Calmer” Series Gets its First Software Reshuffle Including Support For Other Devices
Operwrt is an open source operating system that based on the Linux Kernel and specifically designed for small embedded systems and home routers. The core components of OpenWRT are designed to fit small devices with little memory and a-not-so big storage space configured using a web interface or the command line. Developed to run on various SFF systems, you can find the program not only routers but on phones, residential gateways and in some cases, laptops.
The “Chaos Calmer” series of the software has gotten its first major update pushing it to version 15.05.1 from 15.05. The update is expected to bring improvements to many internal components and most importantly to the core Linux Kernel — which has been upgraded to version 3.18.23 — the main purpose of which is to is to fix the keyring reference leakage. Other components that received improvements were the OpenSSL 1.0.2f toolkit, Samba 3.6, netifdd, uhttpd, rpcd, uce procd, ubox and hostapd.
The new update did also fix some minor issues which caused embedded devices to continuously restart, the culprit being the igmppoxy file which has now been updated. The new Linux Kernel is part of the Long-term support lineup meaning it will contain numerous other fixes to the multicast-to-unicast and ramoverlay.
Several drivers like ledtrig-netdev, bcm47xxpart which is responsible for booting bcm53xx on NAND with bad blocks, brcmfmac –improved TX power support, beamforming support, and stations dumping –8139c, solos-pci (which received an improved RX headroom), xrx200-net, and mac80211 all were refurbished.
The new OpenWRT software update brings support for devices that were not supported in the previous version of the program like Linksys WRT1900ACS (mvebu), Linklt Smart 7688 (ramips), TP-LINK TL-WR841N.ND V10 (ar71xx), D-LINK DIR-615 rev. Lx (ar71xx), ZBT WG2626B (ramips), and Linksys WRT1900ACS (mvebu).
Other devices that will also be supported now are the Gainstrong Minibox v1.0 (ar71xx), TP-LINK TL-WR941ND v6 international version (ar71xx) TL-WR741ND v5(ar71) and WR740N v5.0. The Netgear R8000 receive improvements to the USB power and CPU speeds also some Raspberry Pi Mini boards.
