From a4b27035a56b9d9f722cd75931a886c9a3f6db2d Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Fri, 2 Dec 2016 23:06:18 +0000 Subject: [PATCH] module: Disable matching missing version CRC This partly reverts commit cd3caefb4663e3811d37cc2afad3cce642d60061. We want to fail closed if a symbol version CRC is missing, as the alternative may allow subverting module signing.
