Use dlopen for loading libtss2* to avoid OpenSSL dependency Resolves: #2057490 Signed-off-by: Daiki Ueno <dueno@redhat.com>
2022-02-24 13:08:53 +00:00
From 1719288f7e57d6b9593ef0c01fdcf7ac304c099f Mon Sep 17 00:00:00 2001
From: Daiki Ueno <ueno@gnu.org>
Date: Wed, 23 Feb 2022 19:48:52 +0100
Subject: [PATCH] tpm2: dynamically load tss2 libraries as needed
libtss2-esys links to OpenSSL or mbed TLS for cryptography, which may
cause packaging issues. This instead dlopen's tss2 libraries as
needed so non-TPM applications continue working without loading
multiple crypto libraries.
