Canonical Releases Linux 5.0 Kernel (HWE) Security Update for Ubuntu 18.04.2 LTS

Canonical released today a new Linux kernel security update, this time for users of the Ubuntu 18.04.2 LTS operating system using the Linux 5.0 HWE (Hardware Enablement) kernel from Ubuntu 19.04.

This Linux Hardware Enablement (HWE) kernel from Ubuntu 19.04 for Ubuntu 18.04.2 LTS includes the same fixes for four security flaws that Canonical added in the lastest kernel for Ubuntu 19.04 last week, including an integer overflow (CVE-2019-11487) discovered in Linux kernel, which could lead to use-after-free issues as local attackers were able to use the exploit to execute arbitrary code or cause a denial of service (system crash).

Additionally, the security patch addresses a race condition (read more)

Mounting Issues On Your Mac Can Be Resolved

It’s not a dreadful message. Nonetheless, it still is an alarming one. You don’t want to to see the message “Disk Not Ejected Properly” on your screen, do you?

The message “Disk Not Ejected Properly” usually appears when you unplug a cable or disconnect power to a drive without making sure the disk has unmounted from the Finder after selecting it and choosing File > Eject [Name] or clicking the Eject icon next to its name in the sidebar.

It’s a message you don’t expect to see, especially if you’ve just successfully ejected the drive. The thing is, it happens and maybe, you shouldn’t ignore it.

When you mount a drive in the Finder, you expect it to stay there. If you’ve found that your previously reliable external hard disk drive or SSD starts ejecting itself, trouble is obviously afoot.

Here’s something you should do right away when you do see that message.

If unexpected unmountings continue, try to make a backup immediately. This may reveal other problems, but it’s important you have as current a copy of what’s on that drive as possible, as the hardware may be about to die—or the drive may at least be hard to access while you work through solutions.

Mac expert, Glenn Fleishman, shares some possibilities as to why your Mac is not mounting. He also shares some helpful troubleshooting tips.

• A bad cable. Even if you haven’t touched the cable since you attached an external drive years ago to a desktop computer, cables can fail. This is true even if it’s the one included with the drive or you purchased one from a company with strong positive product reviews. Cable failure is more likely for drives that are routinely connected and disconnected to a computer. Swap another identical cable, as it’s the cheapest way to isolate the problem.
• A faulty power connection. Check that the adapter is plugged in to the drive firmly and that the AC power plug isn’t jiggling in the outlet or surge protector. If the drive has a power light separate from an activity LED, observe it

Linux Kernel 5.1 Reached End of Life, Users Urged to Upgrade to Linux Kernel 5.2

Renowned Linux kernel developer Greg Kroah-Hartman announced that the Linux 5.1 kernel series has reached end of life, urging users to upgrade to the latest Linux 5.2 kernel series.

Announced in early May 2019, the Linux 5.1 kernel series brought the ability to use persistent memory as RAM, as well as support for booting to a device-mapper device without using initramfs, support for cumulative patches in live kernel patching, and more preparations for year 2038.

In addition, Linux kernel 5.1 introduced support for configuring Zstd compression levels in the Btrfs file system, more faster and scalable asynchronous I/O, improved power management, scalable monitoring of large filesystems, as well as numerous new and updated drivers for better hardware support.

However, as all good things must come to an end, the Linux 5.1 kernel has now reached end of life with the 5.1.21 maintenance update released by Greg Kroah-Hartma… (read more)

Canonical Announces Amazon EC2 On-Demand Hibernation for Ubuntu 18.04 LTS

Canonical and AWS announced today the public availability of on-demand Amazon EC2 Hibernation support for the Ubuntu 18.04 LTS operating system on AWS (Amazon Web Services).

As one can imagine, the Amazon EC2 On-Demand Hibernation functionality lets users start up Amazon EC2 instances, configure them to their needs, hibernate them, and then launch them again whenever they want with all the running apps in the last state before they were put to sleep.

With Amazon EC2 On-Demand Hibernation there’s no need to rebuild the memory footprint of your apps, and it also lets you maintain a fleet of pre-warmed Amazon EC2 instances that may increase your productivity without the need to modify any of your existing applications in the cloud.

If you’re using Ubuntu on AWS (Amazon Web Services), you can now benefit of Amazon EC2 On-Demand Hibernation in… (read more)

Collabora Brings VR Support to Linux Desktop Environments, Sponsored by Valve

Collabora today announced a new open-source project that promises to enable Linux-based desktop environments and window managers to be aware of VR (virtual reality).

Sponsored by Valve, the xrdesktop project is developed by Collabora and designed to integrate into existing desktop environments like KDE and GNOME, making them running in virtual reality (VR) runtimes. It does that by rendering windows in 3D space, allowing users to manipulate them with VR controllers and headsets.

“This integration of xrdesktop into the window managers enables mirroring existing windows into XR and to synthesize desktop input through XR actions. xrdesktop can be run as a dedicated scene application, but it also features an overlay mode, where desktop windows are overlaid over any other running VR application,” explains Collabora’s Lubosz Sarnecki.

Canonical Releases New Linux Kernel Live Patch for Ubuntu 18.04 and 16.04 LTS

Canonical released a new Linux kernel live patch for its long-term supported Ubuntu 18.04 LTS and Ubuntu 16.04 LTS operating system series to address five security vulnerabilities.

Coming hot on the heels of the last Linux kernel security updates released by Canonical last week for all supported Ubuntu Linux releases, this new kernel live patch is now available for users of the Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 16.04 LTS (Xenial Xerus) operating systems who use the Canonical Livepatch Service to apply rebootless kernel updates.

It fixes five security issues, including a race condition (CVE-2019-11815), which could lead to a use-after-free, in Linux kernel’s RDS (Reliable Datagram Sockets) protocol implementation that may all… (read more)
