Date: Thu, 07 Jan 2010 01:27:01 -0800 (PST) From: David Miller <davem@...emloft.net> To: therbert@...gle.com Cc: netdev@...r.kernel.org, lorenzo@...gle.com Subject: Re: [PATCH] IPv6: fix rt_lookup in pmtu_discovery From: Tom Herbert <therbert@...gle.com> Date: Wed, 6 Jan 2010 20:43:48 -0800 > In rt6_pmtu_discovery a route lookup is done constrained to the > receiving interface of the ICMP message. In the case of an asymmetric > routing, the receive interface may be different than the sending > interface, so no route will be found in such cases and pmtu is never > correctly set in the route to the destination. This patch fixes that > by not using the receive interface in the lookup. > > Signed-off-by: Tom Herbert <therbert@...gle.com> This needs to do what the IPV4 side does, iterate over specific then "any" device index, doing a lookup for each case until the route is found, therefore starting from more specific and going towards less specific routes. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
