From 0dd8e06bdaa0a97e706ee1a489a1f6176c4ddc64 Mon Sep 17 00:00:00 2001 From: Chris Wright Date: Tue, 3 May 2005 14:01:15 +0100 Subject: [PATCH] add new audit data to last skb When adding more formatted audit data to an skb for delivery to userspace, the kernel will attempt to reuse an skb that has spare room. However, if the audit message has already been fragmented to multiple skb's, the search for spare room in the skb uses the head of the list. This will corrupt the audit message with trailing bytes being placed midway through the stream. Fix is to look at the end of the list.
