FOSSASIA 2019 Schedule – March 14-17

As its name implies, FOSSASIA is a Free and Open Source Software event taking place every year in Asia, more specifically in Singapore. I first discovered it last year, and published a virtual FOSSASIA 2018 schedule last year to give an idea about the subjects discussed at the event. It turns out FOSSASIA 2019 is coming really soon, as in tomorrow, so I’m a bit late, but I’ll still had a look at the schedule and made my own for the 4-day event. Thursday – March 14, 2019 10:05 – 10:25 – For Your Eyes Only: Betrusted & the Case for Trusted I/O by Bunnie Huang, CTO Chibitronics Security vulnerabilities are almost a fact of life. This is why system vendors are increasingly relying on physically separate chips to handle sensitive data. Unfortunately, private keys are not the same as your private matters. Exploits on your local device still have […]

$100 Reolink Argus 2 is a Wire-Free IP Camera with Optional Solar Panel

This morning I had a look at battery-powered IP cameras since they avoid the hassle of wiring power and/or Ethernet around the house. I could remember I covered Immedia Blink IP camera with up to 2-year battery life back in 2014, and the company did very well since it got acquired by Amazon, and Blink IP security camera is now sold on Amazon US for $99.99 and up. It’s probably one of the best, if not the best options, for low-cost battery-powered cameras but the problem is that they only ship to a limited number of countries. Last year, there was a new entrant with Eufy Evercam outdoor IP camera with up to one year of battery life, but again it’s not easy to purchase from overseas, and the price starts at $279.99 for a single camera system. I also covered a solar and battery powered IP camera made by […]

Adiantum Enables Faster File Encryption in Devices without AES Crypto Accelerator

File Encryption is enabled – even required – by default in most Android devices, as it protects your data would you lose your phone, or have it stolen. Encryption in Android leverages the Advanced Encryption Standard (AES), and most modern 64-bit processors – like the ones based on Armv8 – come with a crypto accelerator that boosts performance several folds compared to a software only solution. But there are also many low end devices, for example based on Arm Cortex-A7, that lack crypto extensions, and enabling AES encryption would make the devices even slower than they already are. So in order to provide file encryption on entry-level hardware without comprising too much on performance, Google has developed Adiantum encryption optimized to run on targets without crypto accelerator. As explained in a Google Security blog post, Adiantum uses the ChaCha stream cipher – as used in HTTPS – in a length-preserving […]

GL-USB150 OpenWrt Microrouter Looks Like a USB Flash Drive

There are plenty of small low cost routers capable of running OpenWrt, including the TP-Link WR703N or Marstek MPR-N9 model which we covered several year ago. GL.inet also made several tiny routers that ended up being supported by OpenWrt, including their GL-USB150 microrouter that looks like a USB flash drive, but is really an Atheros AR9331 router that can be powered by any USB ports. GL-USB150 microrouter specifications: CPU – Qualcomm QCA9331 (Atheros AR9331) MIPS processor @ 400MHz System Memory – 64MB DDRII Storage – 16MB NOR Flash Connectivity – 2.4GHz 802.11b/g/n WiFi up up 150Mbps transmission rate Power input – 5V/1A via USB port Power consumption – <1W Dimension – 82x24x11mm Weight – 10 grams There’s no Ethernet port, no extra USB port to add 3G/4G connectivity, and the microrouter can either be accessed wirelessly when connected to a power bank, or via Ethernet over USB when connected to […]

FOSDEM 2019 Open Source Developers Meeting Schedule

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where developers meet on the first week-end of February to discuss open source software & hardware projects. FOSDEM 2019 will take place on February 2 & 3, and the schedule has already been published with 671 speakers scheduled to speak in 711 events themselves sorted in 62 tracks. Like every year, I’ll create a virtual schedule based on some of the sessions most relevant to this blog in tracks such as open hardware, open media, RISC-V, and hardware enablement tracks. February 2 10:30 – 10:55 – VkRunner: a Vulkan shader test tool by Neil Roberts A presentation of VkRunner which is a tool to help test the compiler in your Vulkan driver using simple high-level scripts. Perhaps the largest part of developing a modern graphics driver revolves around getting the compiler to […]

Linux 4.19 Release – Main Changes, Arm and MIPS Architectures

With Linus Torvalds taking a leave from the Linux kernel project, Greg Kroah-Hartman was the one to release Linux 4.19 last Sunday: Hi everyone! It’s been a long strange journey for this kernel release… While it was not the largest kernel release every by number of commits, it was larger than the last 3 releases, which is a non-trivial thing to do. After the original -rc1 bumps, things settled down on the code side and it looks like stuff came nicely together to make a solid kernel for everyone to use for a while. And given that this is going to be one of the “Long Term” kernels I end up maintaining for a few years, that’s good news for everyone. A small trickle of good bugfixes came in this week, showing that waiting an extra week was a wise choice. However odds are that linux-next is just bursting so […]

Check for Spectre, Meltdown, and L1 Terminal Fault Vulnerabilities with Spectre-meltdown-checker Script

Yesterday, we wrote a little bit about the new speculative execution vulnerability known as L1 Terminal Fault (L1TF) or Foreshadow, and a reader – MHSadri – pointed to an interesting script that checks for all three speculative execution vulnerabilities, and runs in Linux and BSD (FreeBSD, NetBSD, DragonFlyBSD) across multiple architectures: Intel x32, AMD64, Arm and ARM64. Other architectures will also work, but mitigation reporting may not be correct. So I tried it on my own machine, a computer running Ubuntu 18.04 on an AMD FX8350 processor. Installation is easy:

git clone https://github.com/speed47/spectre-meltdown-checker/
cd spectre-meltdown-checker

1 2	git clone https://github.com/speed47/spectre-meltdown-checker/ cd spectre-meltdown-checker

The developer recommends to check the script manually first, just for security sake. You can have two way to run it: either directly inside your OS, or via docker which may be a better idea since it would not be able to mess with your system especially I had to run it with sudo to avoid permission issues. Here’s […]
