Linux.Darlloz Worm Targets Embedded Linux Devices

Symantec has recently discovered a new Linux worm, called Linux.Darlloz, that targets Internet-enabled devices running Linux in addition to traditional computers. That means devices such as home routers, set-top boxes and security cameras could be at risk of infection, although no attacks against non-PC devices have been confirmed yet. The worm exploits an “old” PHP vulnerability, which was patched in May 2012 (PHP 5.4.3, and PHP 5.3.13), and currently only affects Intel (x86) based systems. So you’d need an embedded system powered by an Intel processor, running Linux and PHP to be at risk. Having said that, Symantec also explains code for other architectures such as ARM, PPC, and MIPS, is also present in the worm, and these systems could potentially be at risk too with small modifications. Here’s how the worm operates: Upon execution, the worm generates IP addresses randomly, accesses a specific path on the machine with well-known […]

Imagination Technologies Announced MIPS P5600, the First “Warrior” Core

At the end of June, Imagination Technologies unveiled their MIPS Series5 ‘Warrior’ architecture, featuring 32-bit and 64-bit CPU cores, with features such as hardware and software virtualization, and Extended Virtual Addressing (EVA). The company has recently announced the first member of the family with their MIPS P5600 CPU IP core. The MIPS P5600 core is a 32-bit CPU IP that is said to offer 1.2 to 2x more system performance compared to proAptiv cores, and it supports peak frequencies above 2GHz on TSMC’s 28HPM process node. Performance-wise the core achieves 5 CoreMark/MHz and 3.5 DMIPS/MHz for a single core, which appears to be equivalent to ARM Cortex A15 according to values listed in Wikipedia and EEMBC Coremark results. MIPS P5600 features and benefits: 32-bit MIPS32 Release 5 Instruction Set Architecture 16-stage, wide issue, out-of-order (OoO) pipeline Quad instruction fetch per cycle Triple bonded dispatch per cycle Instruction peak issue of […]

$27 TP-LINK TL-MR10U is an Hackable OpenWRT Wi-Fi Router with a Power Bank

TP-Link WR703N is a cheap 802.11 b/g/n router (you can now get it for about $20) that can easily be hacked to run openWRT and for example, act as an home automation gateway, printer server and more.  But if you need a battery powered router for your application, TP-Link TL-MR10U,  based on similar hardware as TL-703WR, should be a better match as it comes with a 2600 mAh battery, and costs just about $27 on DealExtreme. Here are the specifications of the device: CPU – Atheros AR9331 CPU @ 400Mhz System Memory – 32MB RAM Storage – 4 MB Flash Connectivity: 10/100 Mbit Ethernet port 802.11 b/g/n 150Mbps 3G support via external USB dongle USB – USB 2.0 port + micro-USB port for power Misc – Serial port access Dimensions – 91mm x 43mm x 25.85mm（L x W x H） The device comes with a microUSB cable and a user’s […]

Linux Kernel 3.10 Released

Linus Torvalds has announced the release of Linux Kernel 3.10: So I delayed this by a day, considering whether to do another -rc, but decided that there wasn’t enough upside. Sure, it hasn’t been as quiet as I’d like, and we had this long discussion about an inode list locking scalability issue over the last week or two, but in the end that issue turned out to not be new, and while we may end up back-porting the eventual resolution to 3.10, it wasn’t a reason to delay the release. Similarly, while I might wish for fewer pull requests during the late rc’s (and particularly the ones that came in Friday evening -inconvenient for a weekend release), at some point delaying things doesn’t really help things, and just makes the pent up demand for the next merge window worse. In other words, I could really have gone either way, but […]

Imagination Technologies Unveils MIPS “Warrior” 32 and 64 Bit CPU Cores

Last year, MIPS announced Aptiv Cores, but since then, the company has been bought by Imagination Technologies, and they’ve recently announced updates to the family, as well as new MIPS Series5 ‘Warrior’ CPU cores during Imagination Summit in Asia. Before I write about the update to Aptiv cores, let me remind you of the 3 Aptiv families: proAptiv – High performance cores (3.5DMIPS/Mhz) to be used in SoC for smartphone, tablets, …. 1 to 6 cores. Roughly equivalent to ARM Cortex A15. interAptiv – Medium performance core (1.7DMIPS/MHz) for mainstream STB, digital cameras, mid-range smartphones. 1 to 4 cores. Equivalent to ARM Cortex A5 microAptiv – Low power MCU and MPU cores Imagination has added a small-footprint single-core version to the interAptiv family without the extra logic associated with multi-core coherency and L2 cache controller, as well as a floating point version to the microAptiv family for applications such as […]
