From 6d503d2a47324c15c5b4274bf4dd016064143754 Mon Sep 17 00:00:00 2001 From: Daniel Gustafsson Date: Thu, 10 Feb 2022 14:23:36 +0100 Subject: [PATCH] Set SNI ClientHello extension to localhost in tests The connection strings in the SSL client tests were using the host set up from Cluster.pm which is a temporary pathname. When SNI is enabled we pass the host to OpenSSL in order to set the server name indication ClientHello extension via SSL_set_tlsext_host_name. OpenSSL doesn't validate the hostname apart from checking the max length, but LibreSSL checks for RFC 5890 conformance which results in errors during testing as the pathname from Cluster.pm is not a valid hostname. Fix by setting the host explicitly to localhost, as that's closer to the intent of the test. Backpatch through 14 where SNI support came in.
