From 9552389c465ed1ded39edf4a5642a861b53c2955 Mon Sep 17 00:00:00 2001 From: Gilad Ben-Yossef Date: Tue, 2 Jul 2019 14:39:20 +0300 Subject: crypto: fips - add FIPS test failure notification chain Crypto test failures in FIPS mode cause an immediate panic, but on some system the cryptographic boundary extends beyond just the Linux controlled domain. Add a simple atomic notification chain to allow interested parties to register to receive notification prior to us kicking the bucket.
