New OpenELA compatibility toolset reduces testing costs for Enterprise Linux distributors
OpenELA has introduced ELValidated, an open source verification and interoperability suite that gives organizations and developers the ability to verify the compatibility of their Enterprise Linux distributions.
Software and hardware vendors and Linux developers can use ELValidated to help ensure their applications run reliably across compatible Enterprise Linux distributions—without modifications or recompilation. It also helps validate changes between OS releases, helping verify that features added to a given operating system haven’t broken compatibility with earlier versions. With ELValidated, organizations and developers can reduce the risk of breaking compatibility while expanding support without added testing costs.
The Press Release has additional details. |

| Product Highlights | Oracle Linux 9.6 now generally available
The Oracle Linux team is pleased to announce the general availability of Oracle Linux 9.6 on both Intel/AMD x86_64 and Arm aarch64 platforms. Oracle Linux 9.6 is 100% application binary compatible with the corresponding Red Hat Enterprise Linux 9.6 release and delivers on Oracle's commitment to keeping Linux open and free for everyone. As a founding member of the Open Enterprise Linux Association (OpenELA), Oracle continues to contribute, maintain, and support Enterprise Linux source code.
The Unbreakable Enterprise Kernel 8 (UEK 8)—the latest release of Oracle’s purpose-built Oracle Linux kernel—is included as the default kernel in Oracle Linux 9.6 ISO installations. Oracle Linux 9.6 also delivers new capabilities and enhancements spanning security, networking, container technologies, and the developer experience.
Read more in the Oracle Linux 9.6 announcement blog.
Announcing UEK 8.1 general availability
The Unbreakable Enterprise Kernel 8 Update 1 (UEK 8.1) v6.12.0-100.28.2 is now generally available.
UEK 8.1 is based on the long term support 6.12 kernel release and is currently supported with Oracle Linux 9 on both Intel/AMD x86_64 and Arm aarch64 platforms. This release incorporates fixes from v6.12.28 of the 6.12.y stable branch.

Oracle Linux 9 achieves security certifications under Common Criteria and FIPS 140-3
Oracle Linux 9 has recently reached major milestones in security certification.
It is now Common Criteria (CC) certified under the National Information Assurance Partnership (NIAP) General Purpose Operating System Protection Profile (OSPP) 4.3, demonstrating compliance with rigorous international security standards. As a result, Oracle Linux 9 is officially listed on the NIAP Product Compliant List, reinforcing its position as a secure and trusted operating system for enterprise and government use.

| Developers Corner | Understanding Linux mount and unmount operations
Mounting and unmounting filesystems are fundamental tasks in Linux system administration. After a filesystem is created, it can't be used immediately—it must first be mounted to make its contents accessible to users. Later, when it's no longer needed, the filesystem can be unmounted, making its contents inaccessible, even if the physical device remains connected.
The mount operation sets up in-memory structures, initializes the superblock, and links the filesystem’s root directory to a specified mount point. In contrast, umount cleans up: it breaks references, frees resources, and detaches the filesystem.
This blog, takes a closer look at what actually happens during the sys_mount and sys_umount system calls.
BPF: making split BPF type format (BTF) more resilient
eBPF is a powerful technology originating from the Linux kernel that enables sandboxed programs to run safely in privileged contexts, such as the kernel itself. It allows extending kernel functionality efficiently—without modifying kernel source code or loading additional modules.
In this blog entry, we explore the concept of split BPF Type Format information (BTF) and its value. We examine the challenges it introduces for kernel modules that aren't built alongside the kernel, and present the solution developed by the BPF community to address this issue. This solution is now available both upstream and in UEK 8, Oracle’s Linux kernel based on the stable 6.12 release.
Can NUMA balancing be cgroup-aware?
Linux NUMA (Non-Uniform Memory Access) balancing improves performance by optimizing how memory is accessed across NUMA nodes. However, until now, it hasn’t been cgroup-aware. This means even workloads pinned to a single NUMA node (via cpuset.mems) can trigger unnecessary page faults and scanning.
A recent kernel patch addresses this by detecting pinned workloads early, allowing the system to bypass unnecessary NUMA activity—delivering up to 30% performance gains and helping to eliminate overhead for memory that can’t be migrated.
A simple fix with big impact. Read the blog to learn all the details . |
