From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jiri Benc Subject: [PATCH net-next 0/4] iptunnel: scrub packet in iptunnel_pull_header Date: Thu, 18 Feb 2016 11:22:48 +0100 Message-ID: Cc: Jesse Gross , "John W. Linville" , Pravin B Shelar To: netdev@vger.kernel.org Return-path: Received: from mx1.redhat.com ([209.132.183.28]:44758 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1426118AbcBRKXk (ORCPT ); Thu, 18 Feb 2016 05:23:40 -0500 Sender: netdev-owner@vger.kernel.org List-ID: As every IP tunnel has to scrub skb on decapsulation, iptunnel_pull_header tried to do that and open coded part of skb_scrub_packet. Various tunneling protocols (VXLAN, Geneve) then called full skb_scrub_packet on their own, duplicating part of the scrubbing already done. Consolidate the code, calling skb_scrub_packet from iptunnel_pull_header. This will allow additional cleanups in VXLAN code, as the packet is scrubbed early during rx processing after this patchset and VXLAN can start filling out skb fields earlier. The full picture of vxlan cleanup patches can be seen at: https://github.com/jbenc/linux-vxlan/commits/master Jiri Benc (4): geneve: implement geneve_get_sk_family helper geneve: move geneve device lookup before iptunnel_pull_header vxlan: move vxlan device lookup before iptunnel_pull_header iptunnel: scrub packet in iptunnel_pull_header drivers/net/geneve.c | 98 +++++++++++++++++++++++++++-------------------- drivers/net/vxlan.c | 25 ++++++------ include/net/ip_tunnels.h | 3 +- net/ipv4/ip_gre.c | 2 +- net/ipv4/ip_tunnel_core.c | 8 ++-- net/ipv4/ipip.c | 2 +- net/ipv6/sit.c | 2 +- 7 files changed, 76 insertions(+), 64 deletions(-) -- 1.8.3.1
