The Unbreakable Enterprise Kernel (UEK) for Oracle Linux provides the latest open source innovations and key optimizations and security to enterprise cloud workloads. It is the Linux kernel that powers Oracle Cloud and Oracle Engineered Systems such as Oracle Exadata Database Machine as well as Oracle Linux on Intel-64, AMD-64 or ARM hardware. What's New? UEK R5 Update 3 is based on the mainline kernel version 4.14.35. Through actively monitoring upstream check-ins and...

In this blog, Oracle Linux kernel developer Manjunath Patil demostrates how you can configure your Oracle Linux instances (both bare metal and virtual machine) running in Oracle Cloud for crash dumps. OCI instances can generate a vmcore using kdump. kdump is a mechanism to dump the 'memory contents of a system' [vmcore] when the system crashes. The vmcore later can be analyzed using the crash utility to understand the cause of the system crash. The kdump mechanism works by...

Oracle Linux kernel developer Daniel Jordan contributes this post on enhancing the performance of padata. padata is a generic framework for parallel jobs in the kernel -- with a twist. It not only schedules jobs on multiple CPUs but also ensures that each job is properly serialized, i.e. finishes in the order it was submitted. This post will provide some background on this somewhat obscure feature of the core kernel and cover recent efforts to enhance its parallel performance...

Chuck Lever is a Linux Kernel Architect working with the Oracle Linux and Unbreakable Enterprise Kernel team at Oracle. He contributed this article about replacing printk debugging with static trace points in the kernel. On The Benefits of Static Trace Points These days, kernel developers have several choices when it comes to reporting exceptional events. Among them: a console message; a static trace point; Dtrace; or, a Berkeley Packet Filter script. Arguably the best choice...

XFS Upstream maintainer Darrick Wong provides another instalment, this time focusing on how to facilitate sysadmins in maintaining healthy filesystems. Since Linux 4.17, I have been working on an online filesystem checking feature for XFS. As I mentioned in the previous update, the online fsck tool (named xfs_scrub) walks all internal filesystem metadata records. Each record is checked for obvious corruptions before being cross-referenced with all other metadata in the...

Following on from his recent blog XFS - 2019 Development Retrospective, XFS Upstream maintainer Darrick Wong dives a little deeper into the Reflinks implementation for XFS in the mainline Linux Kernel. Three years ago, I introduced to XFS a new experimental "reflink" feature that enables users to share data blocks between files. With this feature, users gain the ability to make fast snapshots of VM images and directory trees; and deduplicate file data for more efficient use...
