From 4256f1aaa662697c1faa0984b7a698c2c8c57735 Mon Sep 17 00:00:00 2001 From: Julian Anastasov Date: Sun, 17 Oct 2010 16:29:40 +0300 Subject: [PATCH] ipvs: fix CHECKSUM_PARTIAL for TUN method The recent change in IP_VS_XMIT_TUNNEL to set CHECKSUM_NONE is not correct. After adding IPIP header skb->csum becomes invalid but the CHECKSUM_PARTIAL case must be supported. So, use skb_forward_csum() which is most suitable for us to allow local clients to send IPIP to remote real server.
