From f314dfea16a085a58d2ff227ea9fa9e490ee5d18 Mon Sep 17 00:00:00 2001 From: Jessica Yu Date: Fri, 29 Jun 2018 16:37:08 +0200 Subject: modsign: log module name in the event of an error Now that we have the load_info struct all initialized (including info->name, which contains the name of the module) before module_sig_check(), make the load_info struct and hence module name available to mod_verify_sig() so that we can log the module name in the event of an error.
