From 7a1af5d7bb94af16b980a53330436b9fadc12435 Mon Sep 17 00:00:00 2001 From: Maxime Bizon Date: Tue, 28 Jun 2005 13:21:12 -0700 Subject: [IPV4]: ipconfig.c: fix dhcp timeout behaviour I think there is a small bug in ipconfig.c in case IPCONFIG_DHCP is set and dhcp is used. When a DHCPOFFER is received, ip address is kept until we get DHCPACK. If no ack is received, ic_dynamic() returns negatively, but leaves the offered ip address in ic_myaddr. This makes the main loop in ip_auto_config() break and uses the maybe incomplete configuration. Not sure if it's the best way to do, but the following trivial patch correct this.
