Subject: [PATCH v4 05/11] ima: move ima_file_free before releasing the file
Date: Mon, 28 Mar 2011 12:39:36 -0400	[thread overview]
Message-ID: <1301330382-17745-6-git-send-email-zohar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1301330382-17745-1-git-send-email-zohar@linux.vnet.ibm.com>

Integrity appraisal measures files on file_free and stores the file
measurement as an xattr.  Measure the file before releasing it.
