[LTP] [PATCH v4] IMA: Allow only ima-buf template for key measurement

Hi Lakshmi, Mimi,

merged this one with slightly updated text of docs and commit message.

...

+check_policy_template()
+{
+	while read line; do
+	if ( echo $line | grep -q 'template=') && ( ! echo $line | grep -q 'template=ima-buf' ); then

FYI: parentheses are not necessary, thus I removed them.

+		tst_res TCONF "only template=ima-buf can be specified for KEY_CHECK"
+		return 1
+	fi

Kind regards,
Petr
