For those making use of the Ceph open-source, distributed storage platform, with the upcoming Linux 7.0 kernel they are introducing support for the AES256K key type.
The Ceph authentication code in Linux 7.0 has merged support for the AES256K key type. The CEPH_CRYPTO_AES256KRB5 key type is based on Kerberos 5 / AES256-CTS-HMAC384-192. This support is complementary and doesn’t affect the existing Ceph AES crypto support.
Aside from that Ceph AES256K key type support, the other Ceph changes amount to bug fixes for the Linux 7.0 merge window. See this pull request for those making use of Ceph and curious about these latest changes.
