Oracle Linux 9.0 正式发布
2022-07-07 12:15:00 【开源中国资讯】
面向 Intel-64、AMD-64 (x86_64) 和 Arm (aarch64) 的 Oracle Linux 9 已正式发布,作为 Oracle 的 RHEL 9 的分支。
Oracle Linux 9.0 在镜像中使用的内核版本包括 Unbreakable Enterprise Kernel Release 7 (UEK R7) 以及 Red Hat Compatible Kernel (RHCK)。
带有 UEK R7 的 Oracle Linux 9 提供了内核、性能和安全性增强功能,包括:
- UEK R7 基于 Linux 5.15 LTS 版本,提供最新的硬件支持,与 Linux 内核社区保持一致,更及时地交付关键修复和安全更新,UEK R7 也可用于 Oracle Linux 8。
- Oracle Linux 9 中的OpenSSL 3.0 包括许多新概念和结构增强功能。新 FIPS 模块可防止使用非 FIPS 算法,同时可以在内核中设置 FIPS 标志,而无需将 OpenSSL 切换到 FIPS 模式。
- UEK R7 的文件系统增强功能:包括 Btrfs、新的异步 SSD 修整、并行文件系统同步功能和更少的校验和树查找。XFS 支持直接访问 (DAX) 操作,允许直接访问字节可寻址的持久内存,有助于避免使用传统块 I/O 约定的延迟。NFS 引入了“eager write”挂载选项来帮助减少延迟。
- UEK R7 原生支持 VirtualBox 共享文件夹(vboxsf)。有助于使用 Oracle VM VirtualBox 在 Oracle Linux 来宾和主机操作系统之间共享文件夹。
