[1:1.1.1k-4]

  • Fixes bugs in s390x AES code.
  • Uses the first detected address family if IPv6 is not available
  • Reverts the changes in https://github.com/openssl/openssl/pull/13305
    as it introduces a regression if server has a DSA key pair, the handshake fails
    when the protocol is not explicitly set to TLS 1.2. However, if the patch is reverted,
    it has an effect on the ‘ssl_reject_handshake’ feature in nginx. Although, this feature
    will continue to work, TLS 1.3 protocol becomes unavailable/disabled. This is already
    known - https://trac.nginx.org/nginx/ticket/2071#comment:1
    As per https://github.com/openssl/openssl/issues/16075#issuecomment-879939938, nginx
    could early callback instead of servername callback.
