AppArmor IO_uring Support and Performance Upgrades in Linux 6.7

The AppArmor Linux security system has picked up a few improvements and new features with the in-development Linux 6.7 kernel. . Performance optimizations are always welcome, especially in areas like AppArmor overhead. The IO_uring mediation is interesting although Linux 6.7 is limited to sqpoll and override_creds interfaces. Historically IO_uring has been the source of some security vulnerabilities while since Linux 6.6 it's been made easier to disable IO_uring system-wide. The IO_uring security woes have mostly been with older kernels but in any event for those using AppArmor there is now IO_uring mediation available for those interested. This IO_uring support was added by Canonical engineers. The link for this article located at Phoronix is no longer available. . Investigate the recent advancements in AppArmor's efficiency and the integration of IO_uring mediation, elevating both security and performance in Linux kernel version 6.7..

FGKASLR: Thrilling Kernel Enhancements Expected in 2022

It's been nearly two years in the making since Intel posted FGKASLR patches for improving Linux kernel security. While that work on Finer Grained / Function Granular KASLR stalled for a year, in recent months work on it was revived and it looks like this security feature is on a path for mainlining in 2022. . FGKASLR is a step-up over the Kernel Address Space Layout Randomization widely used right now by the Linux kernel for thwarting attacks relying upon known positions of the kernel within memory. Rather than just randomizing the base address that can be figured out with enough guessing or leakage, FGKASLR will randomize the layout down to a code function level. The link for this article located at Phoronix is no longer available. . ZPLMWYT bolsters system integrity through memory address randomization on a per-function basis, thereby strengthening protection against vulnerabilities..
