Reddit: Using kernel to ensure UDP timestamps are sequences before delivery to user space?

Tuesday 13th of March 2018 07:23:03 PM

Hello all, ran into a strange issue with a legacy app thanks to the introduction of a wireless bridge. Basically we are getting packets out of order and the delivery protocol is UDP. I've been googling hoping to find a proc parameter or some type of iptables trick with no luck. Does anyone know if there is a way to ensure that the user space application receives the IP / UDP packets in order via relative to their timestamp? I realize buffering etc, that this gets complicated in a hurry .. in this particular case a drop is better than an out of order.

Thoughts or clues I might look at?

Thanks so much!

Edit: feeling like a dummy as I already knew this - UDP itself doesn't have a timestamp, only the payload in our case it doesn't have that either. I'll float the question anyhow in case some genius has an idea :D

TuxMachines: Purism Successfully Runs KDE Plasma Mobile on Librem 5 Linux Phone's Test Boards

Tuesday 13th of March 2018 06:09:22 PM

The company, which is known for selling the most secure laptops powered a Linux-based operating system, said in a report that they worked closely with the KDE community to install, run, and enable a mobile network provider service on the Plasma Mobile graphical environment on top of the Debian-based PureOS distribution.

While their Librem 5 Linux phone is far from becoming a reality, Purism's initial enablement of KDE's Plasma Mobile was done on an i.MX 6 development board running their PureOS operating system installed, which is currently based on Debian Testing, and using a Wayland/Weston environment.

TuxMachines: Review: Asus Tinker Board S – Single-Board Computer

Tuesday 13th of March 2018 06:09:05 PM

The Asus Tinker Board S is an ARM-based, single-board computer (SBC) with a quad-core CPU, 2GB RAM and support for 4K video and HD audio. It’s billed as a marvellous computer for DIY enthusiasts and makers.

SBCs are in their ascendancy, in part because of the wide variety of devices available and the unrivaled success of the Raspberry Pi (RPi), offering kids, teachers and hobbyists access to an inexpensive way to embrace computing. In April last year, Asus launched a competitor to the RPi. Their Tinker Board received a promising reception with plaudits given for its hardware specification, and it was generally regarded as a competent platform for building and tinkering.

Nintendo Switch hack + Dolphin Emulator could bring GameCube and Wii game support

This week security researchers released details about a vulnerability affecting NVIDIA Tegra X1 processors that makes it possible to bypass secure boot and run unverified code on some devices… including every Nintendo Switch game console that’s shipped to date. Among other things, this opens the door for running modified versions of Nintendo’s firmware, or alternate operating systems such as a GNU/Linux distribution. And if you can run Linux… you can also run Linux applications. Now it looks like one of those applications could be the Dolphin emulator, which lets you play Nintendo GameCube and Wii games on a computer or other supported devices. Read more

Linux Foundation: New Members, Cloud Foundry, and Embedded Linux Conference + OpenIoT Summit

  • 41 Organizations Join The Linux Foundation to Support Open Source Communities With Infrastructure and Resources
    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced the addition of 28 Silver members and 13 Associate members. Linux Foundation members help support development of the shared technology resources, while accelerating their own innovation through open source leadership and participation. Linux Foundation member contributions help provide the infrastructure and resources that enable the world's largest open collaboration communities.
  • Cloud Foundry for Developers: Architecture
    Back in the olden days, provisioning and managing IT stacks was complex, time-consuming, and error-prone. Getting the resources to do your job could take weeks or months. Infrastructure-as-a-Service (IaaS) was the first major step in automating IT stacks, and introduced the self-service provisioning and configuration model. VMware and Amazon were among the largest early developers and service providers. Platform-as-a-Service (PaaS) adds the layer to IaaS that provides application development and management. Cloud Foundry is for building Platform as a Service (PaaS) projects, which bundle servers, networks, storage, operating systems, middleware, databases, and development tools into scalable, centrally-managed hardware and software stacks. That is a lot of work to do manually, so it takes a lot of software to automate it.
  • Jonathan Corbet on Linux Kernel Contributions, Community, and Core Needs
    At the recent Embedded Linux Conference + OpenIoT Summit, I sat down with Jonathan Corbet, the founder and editor-in-chief of LWN to discuss a wide range of topics, including the annual Linux kernel report. The annual Linux Kernel Development Report, released by The Linux Foundation is the evolution of work Corbet and Greg Kroah-Hartman had been doing independently for years. The goal of the report is to document various facets of kernel development, such as who is doing the work, what is the pace of the work, and which companies are supporting the work.
