Rusty Russell 5e3e2f4e17 run-secret_eq_consttime: try harder. This will never be reliable under high load, without making it unable to detect real errors. But the test is useful because if we don't have this test we'll never notice if we break the const-timedness of our implementation. So, move the calloc out of the test loop (which seems to make it more reliable), and then after we've run it, check the 1-minute load average. Too high, we don't complain about results. It's not perfect, but it's better. Running 100 times (-O3) serially gave 100 successes with the following results: Constant: Within 5% 562-926(832.89+/-73)/1000 times Non-constant: More than 5% slower 860-990(956.35+/-26)/1000 times More importantly, if we swap the const and non-const tests, we get the expected 100 failures: Non-constant: Within 5% 14-79(41.17+/-14)/1000 times Constant: More than 5% slower 44-231(111.89+/-33)/1000 times Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>		5 years ago
