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 <ek@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
