Date: Mon, 27 Sep 2010 15:11:47 +0200 From: Ulrich Weber <uweber@...aro.com> To: Eric Dumazet <eric.dumazet@...il.com> CC: David Miller <davem@...emloft.net>, netdev@...r.kernel.org Subject: Re: [RFC PATCH] dont create cached routes from ARP requests Hi Eric, thanks for the correction! Searched through the log files and discovered that the initial "Neighbor overflow" message was caused by an IPv6 ping scan from the Internet. rt_garbage_collect() is called from dst_alloc and rt_intern_hash. In any case no routes will be freed if the total entries are smaller than ipv4.route.gc_thresh. neigh.default.gc_thresh is static while ipv4.route.gc_thresh is based on system memory. Wouldn't it make sense to set neigh.default.gc_thresh based on system memory too? Cheers Ulrich -- Ulrich Weber | uweber@...aro.com | Software Engineer Astaro GmbH & Co.
