Subject: [PATCH v2 11/23] ima: pass the file descriptor to ima_add_violation()
Date: Mon, 21 Oct 2013 18:42:56 -0400 [thread overview]
Message-ID: <1382395388-8108-12-git-send-email-zohar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1382395388-8108-1-git-send-email-zohar@linux.vnet.ibm.com>
From: Roberto Sassu <roberto.sassu@polito.it>
Pass the file descriptor instead of the inode to ima_add_violation(),
to make the latter consistent with ima_store_measurement() in
preparation for the new template architecture.
