From 92d8682926342d2b6aa5b2ecc02221e00e1573a0 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 4 Feb 2011 15:55:25 -0800 Subject: inetpeer: Move ICMP rate limiting state into inet_peer entries. Like metrics, the ICMP rate limiting bits are cached state about a destination. So move it into the inet_peer entries. If an inet_peer cannot be bound (the reason is memory allocation failure or similar), the policy is to allow. Signed-off-by: David S.
