From a745f7af3cbd04b9c9c9e803429e1c20775b538d Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Thu, 11 Apr 2019 17:11:08 -0700 Subject: [PATCH] selftests/harness: Add 30 second timeout per test In order to keep tests from hanging forever, this adds an alarm signal to each test run. This assumes an individual test doesn't take longer than 30 seconds.
