In 2019, Most Linux Distributions Still Aren't Restricting Dmesg Access

Going back to the late Linux 2.6 kernel days has been the CONFIG_DMESG_RESTRICT (or for the past number of years, renamed to CONFIG_SECURITY_DMESG_RESTRICT) Kconfig option to restrict access to dmesg in the name of security and not allowing unprivileged users from accessing this system log. While it's been brought up from time to time, Linux distributions are still generally allowing any user access to dmesg even though it may contain information that could help bad actors exploit the system.

Last year FreeBSD developers decided to re-base their ZFS file-system code based on the "ZFS On Linux" port rather than the Illumos source tree where they originally had been acquiring the support for this BSD. There's now FreeBSD 12 and FreeBSD 13/Head images available for testing of this re-worked ZFS file-system support.

At Least 27% Of Gentoo's Portage Can Be Easily LTO Optimized For Better Performance

GentooLTO is a configuration overlay for Gentoo's overlay to make it easy to enable Link Time Optimizations (LTO) and other compiler optimizations for enabling better performance out of the Gentoo packages. GentooLTO appears to be inspired in part by the likes of Clear Linux who employ LTO and other compiler optimization techniques like AutoFDO for yielding better performance than what is conventionally shipped by Linux distributions. The GentooLTO developers and users have wrapped up their survey looking at how practical this overlay configuration is on the massive Portage collection.

We've seen many efforts like DXVK that are mapping Direct3D atop Vulkan, efforts like Zink in getting OpenGL over Vulkan, and less popular but still progressing is getting OpenCL -- at least a reasonable subset of it -- working under Vulkan. That's what the CLVK project is about and it's been making more progress since we last looked at it on Phoronix.
