Fedora: F29 Later This Month, Firefox on Wayland, and Josef Strzibny's Upcoming Book

Filed under
Red Hat
  • Fedora 29 Is Now Under Its Final Freeze For Release Later This Month

    As of last night Fedora 29 embarked upon its final freeze as the last step for reaching its official debut by month's end.

    Fedora 29 development is now effectively over except for any granted freeze exceptions or blocker bug fixes. Any other updates will be queued to go down as package updates post-release.

    As of writing, there are eight accepted blocker bugs already ranging from DNF update fails to issues unlocking LUKS-encrypted USB/SD drives from within GNOME to a GNOME Shell Wayland crash.

  • Fedora Developers Update Firefox For Wayland With V-Sync, HiDPI, Better Rendering

    Red Hat / Fedora developers have updated Firefox packages pending for F27 / F28 / F29 that bring a slew of improvements for the web-browser operating under Wayland.

    The updated Firefox 63 and 64 Nightly packages for Fedora Linux users include patches to fix or provide better rendering support, v-sync is now working under Wayland, and there is also working HiDPI scaling support.

    The Firefox-Fedora packages also build with the currently out-of-tree Pipewire WebRTC support too.

  • Firefox on Wayland update

    The builds also ship PipeWire WebRTC patch for desktop sharing created by Jan Grulich and Tomas Popela. Wayland applications are isolated from desktop and don’t have access to other windows (as X11) thus PipeWire supplies the missing functionality along the browser sandbox.

    I think the rendering is generally covered now and the browser should work smoothly with Wayland backend. That’s also a reason why I make it default on Fedora 30 (Rawhide) and firefox-x11 package is available as a X11 fallback. Fedora 29 and earlier stay with default X11 backend and Wayland is provided by firefox-wayland package.

  • Josef Strzibny: I am writing an introductory book to web application deployment

    I decided to write a book (at the very least attempt to). And yes, there will be some Fedora inside!

Games: Kingdom Rush Origins, TinyBuild, Openwashing, Niffelheim, Unleashed, AI War 2, A Gummy's Life, KURSK and Wine

  • Kingdom Rush Origins to release October 18th, Linux support confirmed for release

    Ironhide Game Studio have announced today that Kingdom Rush Origins will release on Steam on October 18th. I've no doubt it will make it to other stores too like GOG and Humble Store like previous games, however they've only mentioned Steam so far.

    I asked the developer on Twitter, if the Linux version would be released at the same time. They replied with "Yes!", so that's really great news for Linux gamers.

  • Humble are allowing you to build your own bundle of TinyBuild games and save some monies

    For those of you craving your latest Linux gaming fix, Humble are doing a build your own bundle with TinyBuild.

    The way it works, is that a ton of games are on sale and if you add at least three to your basket you will get an additional discount. If you add four the discount is higher and higher again if you add five. The saving you can get is kind of ridiculous.

  • Mojang to open source more of Minecraft with two libraries already on GitHub [Ed: This is openwashing; they just free a few bits here and there...]

    I have to admit, I am quite surprised by this. Mojang (owned by Microsoft) are to open source more of Minecraft and they've already started to do so.

  • Niffelheim, a dark survival RPG released recently with Linux support

    It seems we have a few readers interested in Niffelheim emailing it in, a dark survival RPG that follows some elements of Norse mythology that recently released with Linux support.

  • Looks like the 2D open-world sandbox RPG Unleashed is releasing soon

    Unleashed, a 2D open-world sandbox RPG that was funded on Kickstarter is looking pretty good and it's releasing soon with Linux support. I initially covered it back in March this year, as this promising RPG was emailed to us directly by the developer. I completely forgot about it, but thankfully they succeeded in getting funds on Kickstarter with around €10K being pledged. Not a lot, so hopefully the end result is still good.

  • Arcen Games grand strategy game 'AI War 2' to enter Early Access on October 15th

    Nearly two years after the Kickstarter, Arcen Games are ready to bring in more players. AI War 2 is going to enter Early Access on October 15th.

    The sequel to their 2009 hit AI War: Fleet Command, AI War 2 has you take on an overwhelming "inhuman" enemy that has underestimated you. Their currently plan is to remain in Early Access until at least "Q2 2019", although that does depend on how feedback goes and what they need to work on.

  • The amusing multiplayer game A Gummy's Life has left Early Access with an overhauled movement system

    A Gummy's Life is a really fun multiplayer game that can be played with local players and online. It's now left Early Access with a major update.

    I've had quite a lot of fun with this, especially with my Son who adores it because it's completely silly. One thing that wasn't too great was the movement system, which they've actually overhauled as part of the 1.0 update. Movement seems smoother, more responsive and you have a better amount of control with it now too making it an even better experience.

  • First-person adventure about sunken Russian sub KURSK to have a delayed Linux release

    KURSK [Official Site] seems like it's going to be quite a compelling action-adventure game which follows the story of the Russian Kursk submarine disaster back in 2000. I've been following it now for years as it sounds quite interesting, although Linux native gamers have to wait a little longer.

    The developer, Jujubee S.A., has been emailing us their usual press emails about it and it has been clearly mentioning Linux support. However, the Steam store page doesn't mention Linux. After trying to reach them for months over emails, I decided to try Facebook today and they actually responded with a clear "Yes, KURSK will be released on Linux.". Sadly though, the Linux version will come later than the Windows build while they are working to "provide the best possible results on Linux". I've been told the media folks will contact us sometime in regards to the Linux release.

  • Wine's Direct3D Code Will Now Default To OpenGL Core Contexts For NVIDIA GPUs Too

    Earlier this year with Wine 3.9 its Direct3D code changed to default to OpenGL 4.4 core contexts rather than the legacy/compatibility context. NVIDIA GPUs ended up being left at the older value but now that has changed.

    As of yesterday in Wine Git, CodeWeavers' Henri Verbeet has changed the WineD3D code now to also default to OpenGL core contexts for NVIDIA GPUs.

Canonical Releases Important Ubuntu Kernel Live Patch to Fix L1TF, SpectreRSB

Filed under

Available for the Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 16.04 LTS (Xenial Xerus), and Ubuntu 14.04 LTS (Trusty Tahr) operating system series, the new Linux kernel livepatch is rolling out now to all subscribers of the Canonical Livepatch Service. It patches a total of seven security flaws, including the well-known L1 Terminal Fault (L1TF)/Foreshadow and SpectreRSB vulnerabilities.

The two L1FT vulnerabilities fixed in this new kernel livepatch are CVE-2018-3620 and CVE-2018-3646, but it also addresses a flaw that reduced the effectiveness of Spectre Variant 2 mitigations for paravirtual guests (CVE-2018-15594), a use-after-free vulnerability in the IRDA implementation (CVE-2018-6555), and a critical stack-based buffer overflow in the iSCSI target implementation (CVE-2018-14633).

First VyOS 1.2.0 release candidate is available for download

Filed under

This month, the VyOS project turns five years old. In these five years, VyOS has been through highs and lows, up to speculation that the project is dead. Past year has been full of good focused work by the core team and community contributors, but the only way to make use of that work was to use nightly builds, and nightly builds are like a chocolate box a box of WWI era shells—you never know if it blows up when handled or not. Now the codebase has stabilized, and we are ready to present a release candidate. While it has some rough edges, a number of people, including us, are already using recent builds of VyOS 1.2.0 in production, and now it's time to make it public.

  • Strengthening our partner ecosystem at the North America Partner Conference

    Every year we gather our partners, Red Hat executives and industry thought leaders together at our North America Partner Conference to network, learn and celebrate our robust partner ecosystem. This year’s event is especially exciting because 2018 marks Red Hat’s 25th anniversary. It’s a great time to reflect on how much our partner network has grown, look where we’re going in the future and showcase some of the partners who contribute to our success.

  • Open technologies are working together to help patients

    ChRIS Research Integration System (ChRIS)—a collaboration between Boston Children’s Hospital (BCH), the Mass Open Cloud (MOS), and Red Hat—has the potential to change medicine as we know it today.

    It all started in 2003, when the team at BCH set out to make vast amounts of data accessible to researchers and doctors. Ultimately, the team created ChRIS: an image processing application that allows doctors to compare hundreds of thousands of MRI scans in seconds.

    But like any major undertaking, it’s not the goal or the outcome that’s most interesting, it’s the how.

    Here’s a breakdown of how the team achieved their goal: three critical components that worked together to improve patient care.

  • Goodbye JJB, Hello Jenkies Pipeline

    Like so many scripts, I started making Bodhi's test running script in bash before realizing that it was growing too many tentacles and was becoming difficult to extend. I have plans to add an integration test suite to Bodhi that tests it against other dependant network services (such as Koji), and the prospect of getting my bash script to handle that as well with sane input/output options was daunting. Thus, I created bodhi-ci. By using click it was much easier to give it a nice set of subcommands and CLI flags that made it much easier to extend.

    The loss of GNU parallel was a little sad to me, but the features from it that I was using are mostly implemented in Python now. The main thing I'm still missing that I had with is a fully working -x flag, which causes all tests jobs to exit immediately if any one of them fails. I plan to fix this by using Python's async/await API in the future so that I can react to failures in a similar manner, but I'm quite satisfied with the script otherwise. The old script will remain in the repository until I refactor the new script to fully support the failfast flag.


    Enter the Jenkies Pipeline. With some help, I was able to accomplish something much more ideal with my new Jenkiesfile. This solves the resource contention problems described above as Bodhi is now back to using a single node per pull request, and it is able to run the build job once and then fan out to run the individual tests concurrently. In fact, I was able to run the builds in parallel, and have each of those jobs kick off the individual release tests in parallel inside those jobs for double-parallel action. This is very nice since the pip container typically takes about 80% longer to build than the rpm based containers, but we don't have to wait for it to finish to start testing the rpm containers. This means that pull requests start getting results for Fedora 28 tests before the pip container is even finished building. The pipeline can now test a pull request in about 20-30 minutes instead of several hours due to the efficient sharing between tests and the use of a single node.

Google+ and Hyper-Threading (Intel) Compromised

  • Project Strobe: Protecting your data, improving our third-party APIs, and sunsetting consumer Google+

    Many third-party apps, services and websites build on top of our various services to improve everyone’s phones, working life, and online experience. We strongly support this active ecosystem. But increasingly, its success depends on users knowing that their data is secure, and on developers having clear rules of the road.

  • Google+ Is Shutting Down After Data Breach

    Google has decided to shut down the consumer version of its failed social network Google+. This news comes in the wake of a previously undisclosed security flaw that exposed the data of the profile of users.

    The bug in question remained active between 2015 and 2018, and Google discovered it in March; during this period, the flaw affected more than 500,000 users. However, Google claims to have no evidence that suggests that any external developer or app had access to the data.

  • Google Concealed Data Breach Over Fear Of Repercussions; Shuts Down Google+ Service

    Google opted in the Spring not to disclose that the data of hundreds of thousands of Google+ users had been exposed because the company says they found no evidence of misuse, reports the Wall Street Journal. The Silicon Valley giant feared both regulatory scrutiny and regulatory damage, according to documents reviewed by the Journal and people briefed on the incident.

    In response to being busted, Google parent Alphabet is set to announce broad privacy measures which include permanently shutting down all consumer functionality of Google+, a move which "effectively puts the final nail in the coffin of a product that was launched in 2011 to challenge Facebook, and is widely seen as one of Google's biggest failures."

  • Google+ is Dead, Survived By Better Privacy Controls

    Earlier this year, Google started a project to review third-party developer access to Google accounts through the use of APIs. It found a security breach surrounding Google+, and is now shutting the service down, at least for consumers.

    The long and short of the issue is that there was a security hole that allowed third-party developers to access Google+ users’ account data, including name, email address, occupation, gender, and age—even if the account was set as private.. This isn’t particularly sensitive data, but regardless, a breach is a breach.

    The bug was discovered in March of 2018, but was presumed to have been open since sometime in 2015. To make matters slightly more troubling, Google only keeps this particular API’s data log for two weeks…so the company has no way of knowing which users were affected. Presumably, however, some 500,000 users were on the list.

  • Ubuntu does OpenStack

    OpenStack, the open source cloud of choice for many businesses, has seen broad adoption across a large number of industries, from telco to finance, healthcare and more. It’s become something of a safe haven for highly regulated industries and for those looking to have a robust, secure cloud that is open source and enables them to innovate – without breaking the bank.

    For those of you that don’t know, Ubuntu does OpenStack.

    In fact, Ubuntu is the #1 platform for OpenStack and the #1 platform for public cloud operations on AWS, Azure, and Google Cloud, too – meaning that we know our stuff when it comes to building and operating clouds.

    Which is great news because Canonical, the company behind Ubuntu, helps to deliver OpenStack on rails, with consulting, training, enterprise support and managed operations that help your business to focus on what matters most – your applications, not the infrastructure.

Matthias Clasen on Flatpak 1.2 Schedule

Red Hat
  • Flatpak, after 1.0

    One of the easiest ways to help Flatpak is to get your favorite applications on flathub, either by packaging it yourself, or by convincing the upstream to do it.

    If you feel like contributing to Flatpak itself, please do! Flatpak is still a young project, and there are plenty of small to medium-size features that can be added. The tests are also a nice place to stick your toe in and see if you can improve the coverage a bit and maybe find a bug or two.

    Or, if that is more your thing, we have a nice design for improving the flatpak commandline user experience that is waiting to be implemented.

  • Flatpak 1.2 Likely Coming Around Year's End With New Features

    Prolific open-source developer Matthias Clasen at Red Hat has shared some of the post-1.0 plans for the Flatpak app sandboxing/distribution tech. As it stands now, Flatpak 1.2 will likely be out around the end of the calendar year with the next batch of features.

    Flatpak developers have begun merging new feature work onto the Flatpak master branch. Some of the latest work includes better life-cycle control, logging and history support, file copy/paste and drag-n-drop, and a better test suite for regression testing.

    Some of the other work being planned for Flatpak but not yet done is support for using the host OpenGL drivers via libcapsule, application renaming and end-of-life migration for apps, a Dconf/GSettings portal, a portal for web camera access, and greater test coverage.

Linux 4.19-rc8

As mentioned last week, here's a -rc8 release as it seems needed. There were a lot of "little" pull requests this week, semi-normal for this late in the cycle, but a lot of them were "fix up the previous fix I just sent" which implies that people are having a few issues still. I also know of at least one "bad" bug that finally has a proposed fix, so that should hopefully get merged this week. And there are some outstanding USB fixes I know of that have not yet landed in the tree (I blame me for that...) Anyway, the full shortlog is below, lots of tiny things all over the tree. Please go and test and ensure that all works well for you. Hopefully this should be the last -rc release. Read more Also: Linux 4.19-rc8 Released With A Lot Of "Tiny Things"

Kali Linux for Vagrant: Hands-on

I recently saw the announcement for Kali Linux on Vagrant. I have been a huge fan of Kali Linux for a very long time, and I am interested in virtualization (and currently using VirtualBox in an educational environment), so this was a very interesting combination to me. I have now installed it on a few of my systems, and so far I am quite impressed with it. The logical place to start is with a brief overview of Vagrant itself. What is Vagrant? According to their web page: Vagrant is a tool for building and managing virtual machine environments in a single workflow What Vagrant actually does is provide a way of automating the building of virtualized development environments using a variety of the most popular providers, such as VirtualBox, VMware, AWS and others. It not only handles the initial setup of the virtual machine, it can also provision the virtual machine based on your specifications, so it provides a consistent environment which can be shared and distributed to others.

  • Wine-Staging 3.18 Released With Some New Patches While Other Code Got Upstreamed
    It has been a very exciting weekend for Linux gamers relying upon Wine for running Windows titles under Linux... There was the routine bi-weekly Wine 3.18 development release on Friday but yesterday brought transform feedback to Vulkan and in turn Stream Output to DXVK to fix up a number of D3D11 games. Today is now the Wine-Staging 3.18 release. Wine-Staging 3.18 doesn't incorporate any changes around the Vulkan code (there is a Wine patch needed by DXVK for this new functionality), but does include a lot of other stuff. Wine-Staging 3.18 implements more functions in the user32 code, including cascade windows, GetPointerType, and others. On the Direct3D front are a few additions to WineD3D, including the ability for the Direct3D 10 support to work with the legacy NVIDIA Linux driver. There is also a kernel fix for allowing Steam log-ins to work again with Wine Staging.
