Git mirror commit 59f44d20be3f99d181ca742e636d45fc39ec982b. This commit updates OpenSSL to version 1.1.1. This required an update of racoon which uses some internal stuff from OpenSSL and seems to be mostly unmaintained, e.g. there is update in the FreeBSD ports to cope with OpenSSL 1.1.1. Update #3472.
