From 793245eeb97bd28e363f2b0f2e766fdbff0c9619 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Tue, 16 Aug 2005 20:39:38 -0700 Subject: [PATCH] [IPV6]: Fix raw socket hardware checksum failures When packets hit raw sockets the csum update isn't done yet, do it manually. Packets can also reach rawv6_rcv on the output path through ip6_call_ra_chain, in this case skb->ip_summed is CHECKSUM_NONE and this codepath isn't executed.
