From e2fddf5e96df4ac26f2e9ce63053d51cdf3cfe1e Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Fri, 7 Dec 2007 00:44:29 -0800 Subject: [PATCH] [IPV6]: Make af_inet6 to check ip6_route_init return value. The af_inet6 initialization function does not check the return code of the route initilization, so if something goes wrong, the protocol initialization will continue anyway. This patch takes into account the modification made in the different route's initialization subroutines to check the return value and to make the protocol initialization to fail.
