Some users observed that "least connection" distribution algorithm doesn't
handle well bursts of TCP connections from reconnecting clients after
a node or network failure.
This is because the algorithm counts active connection as worth 256
inactive ones where for TCP, "active" only means TCP connections in
ESTABLISHED state. In case of a connection burst, new connections are
handled before previous ones have finished the three way handshaking so
that all are still counted as "inactive", i.e. cheap ones. The become
"active" quickly but at that time, all of them are already assigned to one
real server (or few), resulting in highly unbalanced distribution.
Address this by counting the "pre-established" states as "active".

When using HEAD from
https://git.kernel.org/cgit/utils/kernel/ipvsadm/ipvsadm.git/,
the command:
ipvsadm --start-daemon backup --mcast-interface eth0.60 \
--mcast-group ff02::1:81
fails with the error message:
Argument list too long
whereas both:
ipvsadm --start-daemon master --mcast-interface eth0.60 \
--mcast-group ff02::1:81
and:
ipvsadm --start-daemon backup --mcast-interface eth0.60 \
--mcast-group 224.0.0.81
are successful.
The error message "Argument list too long" isn't helpful. The error occurs
because an IPv6 address is given in backup mode.
The error is in make_receive_sock() in net/netfilter/ipvs/ip_vs_sync.c,
since it fails to set the interface on the address or the socket before
calling inet6_bind() (via sock->ops->bind), where the test
'if (!sk->sk_bound_dev_if)' failed.
Setting sock->sk->sk_bound_dev_if on the socket before calling
inet6_bind() resolves the issue.
