From 0eb5a34cdf34ad07b6db2df1e523aaf6574601b4 Mon Sep 17 00:00:00 2001 From: Auke Kok Date: Wed, 27 Sep 2006 12:53:17 -0700 Subject: e100, e1000, ixgb: Fix an impossible memory overwrite bug We keep getting requests from people that think that this might be an exploitable hole where we would overwrite 4 bytes in the netdev struct if the pci name would exceed 15 characters. In reality this will never happen but we fix it anyway.
