From 8cf229437fd826c32a44546899412b1eb3e1db6f Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 5 Feb 2008 03:15:50 -0800 Subject: [ICMP]: Restore pskb_pull calls in receive function Somewhere along the development of my ICMP relookup patch the header length check went AWOL on the non-IPsec path. This patch restores the check. Signed-off-by: Herbert Xu Signed-off-by: David S.
