Merge branch 'icmp-better-deal-with-ddos'
Eric Dumazet says:
====================
icmp: better deal with DDOS
When dealing with death of big UDP servers, admins might want to
increase net.ipv4.icmp_msgs_per_sec and net.ipv4.icmp_msgs_burst
to big values (2,000,000 or more).
They also might need to tune the per-host ratelimit to 1ms or 0ms
in favor of the global rate limit.
This series fixes bugs showing up in all these needs.
