These flags contain information like whether or not the addresses are inverted or from icmp. The first will allow us to drop an inverse param all over the place, and the second will later be useful in scheduling icmp. Signed-off-by:

RFC 4443 added two new codes values for ICMPv6 type 1: 5 - Source address failed ingress/egress policy 6 - Reject route to destination And RFC 7084 states in L-14 that IPv6 Router MUST send ICMPv6 Destination Unreachable with code 5 for packets forwarded to it that use an address from a prefix that has been invalidated. Codes 5 and 6 are more informative subsets of code 1. Signed-off-by:

Allow setups with large MTU to send large sync packets by adding sync_maxlen parameter. The default value is now based on MTU but no more than 1500 for compatibility reasons. To avoid problems if MTU changes allow fragmentation by sending packets with DF=0. Problem reported by Dan Carpenter. Reported-by:

When the sync damon is started we need to hold rtnl lock while calling ip_mc_join_group. Currently, we have a wrong locking order because the correct one is rtnl_lock->__ip_vs_mutex. It is implied from the usage of __ip_vs_mutex in ip_vs_dst_event() which is called under rtnl lock during NETDEV_* notifications. Fix the problem by calling rtnl_lock early only for the start_sync_thread call. As a bonus this fixes the usage __dev_get_by_name which was not called under rtnl lock. This patch actually extends and depends on commit 54ff9ef3 ("ipv4, ipv6: kill ip_mc_{join, leave}_group and ipv6_sock_mc_{join, drop}"). Signed-off-by:

Instead of using the out-of-line EWMA calculation, use DECLARE_EWMA() to create static inlines. On x86/64 this results in code that's one byte larger (for me), but reduces struct link_ant and struct link size by the two unsigned long values that store the parameters each. Signed-off-by:
