From 2f78e06636061d0b179c6bbf3b50051faec0f7aa Mon Sep 17 00:00:00 2001 From: Erik Kline Date: Wed, 22 Jul 2015 16:38:25 +0900 Subject: ipv6: sysctl to restrict candidate source addresses Per RFC 6724, section 4, "Candidate Source Addresses": It is RECOMMENDED that the candidate source addresses be the set of unicast addresses assigned to the interface that will be used to send to the destination (the "outgoing" interface). Add a sysctl to enable this behaviour. Signed-off-by: Erik Kline Signed-off-by: David S.
