From 263e69cbc9e5a9e7bcf6a24f641ef0717d1ae4df Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 30 Oct 2008 23:11:44 -0700 Subject: [PATCH] pppoe: Fix socket leak. Move SKB trim before we lookup the socket so we don't have to put it on failure. Based upon an initial patch by Jarek Poplawski and suggestions from Herbert Xu. Signed-off-by: David S.
