From 9e5c9fe4cbb89b9af1fcf317f7b39d993bb47a71 Mon Sep 17 00:00:00 2001 From: "Richard W.M. Jones" Date: Tue, 3 May 2016 10:00:17 +0100 Subject: crypto: testmgr - Add a flag allowing the self-tests to be disabled at runtime. Running self-tests for a short-lived KVM VM takes 28ms on my laptop. This commit adds a flag 'cryptomgr.notests' which allows them to be disabled. However if fips=1 as well, we ignore this flag as FIPS mode mandates that the self-tests are run. Signed-off-by: Richard W.M.
