Fedora: Some Fedora 29 Plans, Report for Fedora App, and Flatpak Outline

  • Fedora 29 Aims To Better Support FPGAs

    A rather late self-contained feature proposal for the in-development Fedora 29 is to better support FPGAs.

    Given the growing number of devices appearing with onboard FPGAs thanks to machine/deep learning, AI, and other workloads that can be accelerated on FPGAs, Fedora 29 is aiming to better support them. The support will be focused on FPGAs with good upstream kernel support and utilizing the FPGA manager framework that is vendor-neutral.

  • [Week 9] GSoC Status Report for Fedora App: Amitosh

    You can now subscribe to a particular calendar from the Fedora app!. No more missed meetings. We also take care of converting the date and time to the local timezone so that you get the reminders at the correct time.

    Subscribing to a calendar automatically syncs all events for a calendar on FedoCal to the device calendar. If the device calendar syncs with a sync provider such as Google calendar, you will get the notification in all synced devices. If a meeting is deleted or removed, the reminder will dismissed as well.

  • Flatpak – a look behind the portal

    There are several principles that have guided the design of the existing portals.

    Keep the user in control

    To achieve this, most portals will show a dialog to let the user accept or deny the applications’ request. This is not a hard rule — in some cases, a dialog is just not practical.

    Avoid yes/no questions

    Direct questions about permissions tend to be dismissed without much thought, since they get in the way of the task at hand. Therefore, portals avoid this kind of question whenever possible and instead just let the user get on with the task.

    For example, when an app is requesting to open a file on the host, we just present the user with a fille chooser. By selecting a file, the user implicitly grants the application access to the file. Or he can cancel the file selection and implicitly deny the applications’ request.

    Don’t be annoying

    Nothing is worse than having to answer the same question over and over. Portals make use of a database to record previous decisions and avoid asking repeatedly for the same thing.

    [...]

    If you want to explore how portals work, or just need to double-check which files an app has access to, flatpak has tools that let you do so conveniently.

An update from Fedora Workstation land

Filed under
Red Hat

Feral Interactive, one of the leading Linux game companies, released a tool they call gamemode for Linux not long ago. Since we want gamers to be first class citizens in Fedora Workstation we ended up going back and forth internally a bit about what to do about it, basically discussing if there was another way to resolve the problem even more seamlessly than gamemode. In the end we concluded that while the ideal solution would be to have the default CPU governor be able to deal with games better, we also realized that the technical challenge games posed to the CPU governor, by having a very uneven workload, is hard to resolve automatically and not something we have the resources currently to take a deep dive into. So in the end we decided that just packaging gamemode was the most reasonable way forward. So the package is lined up for the next batch update in Fedora 28 so you should soon be able to install it and for Fedora Workstation 29 we are looking at including it as part of the default install.

Red Hat and CentOS Fix Kernel Bug in Latest OS Versions, Urge Users to Update

Security

It would appear the there was a bug in the previous Linux kernel update for the Red Hat Enterprise Linux 7.5 and CentOS Linux 7.5 releases, which was released to address the Spectre V4 security vulnerability, making connection tracking information to not function correctly, which could lead to connectivity loss and leaking of configuration properties related to the respective connection tracking into other namespaces.

"Previously, the connection tracking information was not cleared properly for packets forwarded to another network namespace," said Red Hat in an advisory. "Packets that were marked with the "NOTRACK" target in one namespace were excluded from connection tracking even in the new namespace. Consequently, a loss of connectivity occasionally occurred, depending on the packet filtering ruleset of the other network namespaces."

RPM And Yum Are A Big Deal For IBM i. Here’s Why

Filed under
Red Hat
Server

By now you’ve probably heard about Yum and RPM, the new processes that IBM will use to deliver open source software to IBM i customers. But you may have questions about how the process works, and what the benefits will be. IT Jungle talked with IBM’s open source guru Jesse Gorzinski to get the low down on why the new tech is so important to the platform.

RPM, which stands for Red Hat Package Manager, is a piece of software created more than 20 years that allows customers in that Linux community to more easily distribute and install the various pieces of software required to create a working Linux environment. Over the years, RPM use has migrated beyond the Red Hat community to other Linux and Unix environments (including AIX), and has essentially become a de facto standard for distributing software in the open source world.

Yum Won't Be Dropped For Fedora 29

Filed under
Red Hat

There had been plans drafted to finish dropping Yum 3 in Fedora now that DNF is quite mature as the next-generation package manager, but that isn't happening now until at least Fedora 30.

Fedora 29 isn't eliminating Yum since it's a fairly disruptive change at this point in the cycle, there still are some important infrastructure components depending upon Yum like Koji, Pungi, and others, among other logistics to work through.
