Subject: ima: Call audit_log_string() rather than logging it untrusted
X-Git-Tag: v4.19~394^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8a3bcaf6ecd37fee326cd30732192ef2a09e5b07;p=platform%2Fkernel%2Flinux-rpi.git

ima: Call audit_log_string() rather than logging it untrusted

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().
