Subject: [PATCH 1/8] ima: Call audit_log_string() rather than logging it untrusted
Date: Thu, 24 May 2018 16:10:58 -0400	[thread overview]
Message-ID: <20180524201105.3179904-2-stefanb@linux.vnet.ibm.com> (raw)
In-Reply-To: <20180524201105.3179904-1-stefanb@linux.vnet.ibm.com>

The parameters passed to this logging function are all provided by
a privileged user and therefore we can call audit_log_string()
rather than audit_log_untrustedstring().
