Ksplice known exploit Detection for io_uring, glibc, overlayfs and netfilter
This post is part of a regular series on Oracle Ksplice’s Known Exploit Detection. For selected security vulnerabilities, not only will Ksplice fix the code error, Ksplice will also lay down tripwires to detect attempts to exploit those fixed vulnerabilities. Known Exploit Detection allows system administrators to report and alarm on future attempts to exploit that vulnerability even after the system has been patched.
Speeding up large memory VM Boot with QEMU ThreadContext
To optimize performance, VMs are commonly configured with preallocated memory as this may help ensure immediate access to resources, avoids fragmentation, and is more predictable than dynamic allocation. In some instances, this can cause slow boot times.
This blog post describes how to use QEMU’s ThreadContext to reduce VM boot time by accelerating memory preallocation.
Detecting kernel memory leaks using adaptivemm
Memory leaks on a system that is designed to put all of the memory to use can be severely disruptive to performance, stability, and availability on the system. Detecting and preventing memory leaks is critically important as kernel memory leaks can be hard to detect.
This blog post reviews various ways to detect memory leaks, focusing on adaptivemm , a daemon that monitors a Linux system proactively.
Btrfs device assembly and verification
Btrfs supports volume management without external configuration files and helps ensure robust device assembly verification and adaptability during mount.
This blog post explores how Btrfs assembles devices and verifies them during mount.
Linux internals: memory UE handling and HWpoison Injection
Read this blog post to learn how userspace memory Uncorrectable Error (UE) is handled by the Linux kernel, userspace handler, as well as the test strategy on Intel/AMD platforms. |

Oracle Cloud Native Environment
The Oracle Cloud Native Environment learning track hands-on Luna labs have been converted to an open source project. This allows customers and partners to run the labs in their own OCI tenancy.
Advantages include:
No time limit to complete the exercise as is the case with Luna labs. Environments can be deployed and used for customer demonstrations because the deployment can be preserved when the lab is terminated. Prerequisites are listed on the open source project page. |
