User space overhaul

Components

ubus - system RPC service netifd - network setup daemon procd - process monitoring

Features:

System wide config reload support Automatic service restart Config validation in backend Web API via JSON-RPC

IPv6 integration

New user space stack, written from scratch Small code size netifd tracks prefixes and delegations

  • dhcp6c - RA / DHCPv6 client
  • dhcpd - routing & address announcement / delegation

Collaboration with industry vendors

Some talks with router vendors (e.g. Linksys) Strange adoption by a few ODMs Better approach: collaboration with chip vendors

Qualcomm Atheros Lantiq MediaTek/Ralink

Collaboration with chip vendors

Differences in motivation

OpenWrt: Code quality, long term health Vendors: Cost reduction, time to market

Red tape, bureaucracy Licensing / IP issues Development process issues
