From 9ba2add3cf5c103b7236f82a023c8ee05a51e4d1 Mon Sep 17 00:00:00 2001 From: Shmulik Ladkani Date: Sun, 2 Dec 2012 01:44:53 +0000 Subject: [PATCH] ipv6: Make 'addrconf_rs_timer' send Router Solicitations (and re-arm itself) if Router Advertisements are accepted As of 026359b [ipv6: Send ICMPv6 RSes only when RAs are accepted], Router Solicitations are sent whenever kernel accepts Router Advertisements on the interface. However, this logic isn't reflected in 'addrconf_rs_timer'. The timer fails to issue subsequent RS messages (and fails to re-arm itself) if forwarding is enabled and the special hybrid mode is enabled (accept_ra=2). Fix the condition determining whether next RS should be sent, by using 'ipv6_accept_ra()'. Reported-by: Ami Koren Signed-off-by: Shmulik Ladkani Signed-off-by: David S.
