First Major Update to Oracle Linux 8 Brings Enhanced Security, Latest Updates

Oracle announced the release and general availability of the first major update to the lasts Oracle Linux 8 operating system series.

Based on the Red Hat Enterprise Linux 8.1 release, Oracle Linux 8 Update 1 is here six months after the release of the Oracle Linux 8 operating system series, which adds a new distribution method combining BaseOS and Applications Streams. It adds updated components and enhanced security to better control and protect your installations on desktop and cloud.

“With Oracle Linux 8, the core operating environment and associated packages for a typical Oracle Linux 8 server are distributed through a combination of BaseOS and Applications Streams. BaseOS gives you a running user space for the operating environment. Application Streams provides a range of applications that were previously distributed in Software Collections, as well as other products and programs, that can run within the user space,” said Oracle.

What’s new in Oracle Linux 8 Update 1

Highlights of Oracle Linux 8 Update 1 include Red Hat Compatible Kernel (RHCK) Linux 4.18.0-147.el8 kernel packages for 64-bit (x86_64) Intel and AMD platforms, which adds bug fixes, security fixes, and enhancements, but also removes support for the Btrfs and OCFS2 file systems, and moves the VDO Ansible module to Ansible packages. Additionally, it adds installation support for 64-bit ARM (AArch64) platforms as a developer preview release.

This release also introduces the Udica to allow users to better control how a container accesses host system resources by creating a tailored security policy. Other updated components include MySQL 8.0, SELinux user-space tools 2.9 with boltd_t SELinux type for managing Thunderbolt 3 devices and bpf SELinux policy for controlling Berkeley Packet Filter, SELinux policy 3.14.3, SETools 4.2.2, OpenSSH 8.0p1, OpenSCAP 1.3.1, and scap-security-guide 0.1.44.

The Cockpit web console has been updated as well in Oracle Linux 8 Update 1 with support for Simultaneous Multi-Threading (SMT) configurations, along with the ability to disable SMT, improvements to the Virtual Machines management page, and an updated Networking page with new firewall settings. Last but not least, this release adds a Memory Mode for the Intel Optane DC Persistent Memory technology, which is transparent to the operating system.

Those interested in running Oracle Linux 8 Update 1 on their personal computers or servers can download the ISO installation images for free right now from the Oracle Software Delivery Cloud, as well as the official Docker images via the Oracle Container Registry and Docker Hub. Users can also download individual RPM packages from the Unbreakable Linux Network (ULN) and the Oracle Linux yum server.
