From 45fae7493970d7c45626ccd96d4a74f5f1eea5a9 Mon Sep 17 00:00:00 2001 From: Roberto Sassu Date: Mon, 19 Dec 2011 15:57:27 +0100 Subject: ima: free duplicate measurement memory Info about new measurements are cached in the iint for performance. When the inode is flushed from cache, the associated iint is flushed as well. Subsequent access to the inode will cause the inode to be re-measured and will attempt to add a duplicate entry to the measurement list. This patch frees the duplicate measurement memory, fixing a memory leak.
