Generic lws_system IPv4 DHCP client - netif and route control via lib/plat apis - linux plat pieces implemented - Uses raw ip socket for UDP broadcast and rx - security-aware - usual stuff plus up to 4 x dns server If it's enabled for build, it holds the system state at DHCP until at least one registered interface has acquired a set of IP / mask / router / DNS server It uses PF_PACKET which is Linux-only atm. But those areas are isolated into plat code. TODOs - lease timing and reacquire - plat pieces for other than Linux
