From 9957a5043e7b0b7361cdf48eea22b2900293e63a Mon Sep 17 00:00:00 2001 From: Mimi Zohar Date: Wed, 9 Mar 2011 22:57:53 -0500 Subject: [PATCH] ima: add inode_post_setattr call Changing an inode's metadata may result in our not needing to appraise the file. In such cases, we must remove 'security.ima'.
