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: 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.

  • iPhone Quarter, ZTE Troubles, Facebook Troubles, Nokia Come-back
     

    So the past month or two? The Quarterly results cycle came in. The item often of great interest is the Apple iPhone performance. 52.2 million iPhones shipped and that gives roughly a flat market share compared to the year before, so about 14%-15%. I'll come and do the full math later of the quarterly data. That race is no longer in any way interesting.

    But two Top 10 smartphone brands ARE in the news. One who is facing imminent death and the other who is making a miraculous return-from-dead. So imminent death and current Top 10 brand first. ZTE. The Trump administration has put a massive squeeze on ZTE and the company is in serious trouble of imminent collapse. Then bizarrely, Trump reversed course and felt he needed to protect CHINESE employment (???) and after yet another typical Trump-mess, we now are at a Never-Neverland where Trump's own party Republicans are revolting against their President and well, ZTE may end up a casualty of this mess. We'll keep an eye on it.
