Version 2 of the cephx authentication protocol (CEPHX_V2 feature bit) is now required by default. It was introduced in 2018, adding replay attack protection for authorizers and making msgr v1 message signatures stronger (CVE-2018-1128 and CVE-2018-1129). Support is present in Jewel 10.2.11, Luminous 12.2.6, Mimic 13.2.1, Nautilus 14.2.0 and later; upstream kernels 4.9.150, 4.14.86, 4.19 and later; various distribution kernels, in particular CentOS 7.6 and later. To enable older clients, set cephx_require_version and cephx_service_require_version config options to 1.
