Description

Windows Server 2022 and Windows 11 introduce AES-256-GCM and AES-256-CCM cryptographic suites for SMB 3.1.1 and therefore offers four ciphers during negotiation:

The illumos kernel aborts negotiation if more than two ciphers are presented, since the original SMB 3.1.1 spec only included two.
