+From fd8b59fb8c576751aef6d59dd5ab208baee2ad49 Mon Sep 17 00:00:00 2001
+From: Stefan Strogin <stefan.strogin@gmail.com>
+Date: Fri, 15 Feb 2019 05:34:55 +0200
+Subject: [PATCH] libkmod-signature: use PKCS7 for LibreSSL or older OpenSSL
+
+Linux kernel uses either PKCS #7 or CMS signing modules (scripts/sign-file.c).
+CMS is not supported by LibreSSL, PKCS #7 is used instead.
+For now modinfo used CMS with no altenative requiring >=openssl-1.1.0
+built with CMS support.
+
+Use PKCS #7 for parsing module signature information when CMS is not available.
+
+Upstream-Status: Submitted [https://patchwork.kernel.org/patch/10814147/]
