Linux Kernel 3.14 Release

Linus Torvalds announced the release of Linux Kernel 3.14 yesterday: So we had a few fairly late changes that I could have done without, but the changelog from -rc8 is still pretty small, and I’m feeling pretty good about it all. If we did end up with any last-minute problems due to the final spurt of patches, they’ll be pretty specific, and it really didn’t make sense to me to delay the release without anything known pending. Much of the final spurt were either marked for stable or known regressions. So 3.14 is out there, and the merge window for 3.15 is thus open. Please do spend the time to test out 3.14, though, even if you might otherwise be in a hurry to send me your pending queue for the next release. Linus Kernel 3.13 brought a scalable block layer for high-performance SSDs, nftables, NFC payment support, squashfs performance […]

ARM TechCon 2013 Schedule – ARM Servers, Internet of Things, Multicore, Hardware and Software Optimization and More

ARM Technology Conference (TechCon) 2013 will take place on October 29 – 31, 2013, in Santa Clara, and the detailed schedule for the event has just been made available. In the previous years, the conference was divided into Chip Designs day (1 day), and the other 2 days were reserved for Software & System Design, but this year it does not appear to be the case. Whether you’ll be able to attend the event or not, it’s worth having a look at what will be discussed there in order to have a better understanding of what will be the key ARM developments in the near future in terms of hardware and software. There will be around 90 sessions categorized into 15 tracks: Accelerating Hardware Development – This track explores the resources, tools, and techniques that designers can employ to quickly bring hardware to market. Topics include multicore design, ARM IP, […]

IEEE Updates 802.11 Standard to Support 600Mb/s Wi-Fi and Approves 802.1aq Standard for Large Ethernet Networks

IEEE has recently announced a standard update for WiFi (802.11-2012) which adds support for 3.7 GHz bands, 600Mb/s throughput and mesh networking among other things, and approved 802.1aq Shortest Path Bridging standard, which will streamline the creation and management of large Local and Metropolitan Area networks by using the next-generation VLANs. IEEE Wi-Fi 802.11-2012 Standard IEEE 802.11-2012 is the 4th revision of the Wi-Fi standard. It has been expanded by supporting faster and more secure devices, while offering improved Quality of Service and cellular network hand-off. Key amendments to the standard: IEEE 802.11n now defines MAC and PHY modifications to enable throughput up to a maximum of 600Mb/s Direct-link setup “Fast roam” Radio resource measurement Operation in the 3650-3700MHz band Vehicular environments, mesh networking, security, broadcast/multicast and unicast data delivery Interworking with external networks and network management. IEEE 802.11 is available for purchase for $5 at the IEEE Standards Store. […]

Bump In Host on Android – IPv4 to IPv6 Translation – Android Builder Summit

Yonghui Wang, representative of China Mobile to the Linux Foundation, gives a presentation about BIH (Bump in the Host) protocol at the Android Builder Summit in February 2012. Abstract: BIH or Bump-in-the-host realizes a host-based IPv4 to IPv6 protocol translation mechanism that allows a class of IPv4-only applications that work through NATs to communicate with IPv6-only peers on Android. The host on which applications are running may be connected to IPv6-only or dual-stack access networks. BIH hides IPv6 and makes the IPv4-only applications think they are talking with IPv4 peers by local synthesis of IPv4 addresses. China Mobile has released an open source implementation of the protocol. The presentation slides has not available for this talk.

Adapting Your Network Code For IPv6 Support – ELC 2012

Mike Anderson, CTO and Chief Scientist at The PTR Group, discloses how to bring your network code up to speed for IPv6. Abstract: IPv6 support is no longer a “sometime in the future” thing. We’ve exhausted the IPv4 address space and need to start transitioning our code to support IPv6. But, is this a big thing or a little thing? This presentation will outline the typical changes that need to be made to networking code to support IPv6 and describe transition strategies to enable use in a dual-stack environment. The target audience for this presentation is developers who want to take advantage of the new IPv6 address space. This presentation is targeted at intermediate-level developers with some understanding of the IP protocol stack.

The Internet of Things – ELC 2012

Mike Anderson, CTO and Chief Scientist for The PTR Group, discusses the Internet of things at Embedded Linux Conference 2012. Abstract: Consumers increasingly want inter-operability of their devices. They want to program their DVR via their mobile phone. They want their music available everywhere. They want their television to update social networking sites. But, as developers, how do we make this possible? This presentation will discuss the imminent “Internet of things” and how we can extend connectivity to previously “dumb” devices like TVs, refrigerators, and other appliances and how this connectivity is directly related to IPv6 support. The target audience for this presentation are platform developers looking to enable connectivity in a new class of intelligent appliances. This presentation is targeted at introductory-level developers with some understanding of the IP protocol stack. You can also download the presentation slides on elinux.org.

How to Find IP Address Ranges Owned by a Company

If you have a firewall, you may want to whitelist and/or blacklist some IPs depending in the origin. Usually it’s easy to find the owner of an IP address, but how can you find the IP address(es) registered by one specific company ? Let’s say you want to whitelist Technorati bot. A simple way is to go to http://bgp.he.net/ and enter the company name (e.g. technorati). It will return the IP list as follows: Result Description AS16936 Technorati, Inc. 208.66.66.0/23 Technorati, Inc. 208.66.65.0/24 Technorati, Inc. 208.66.64.0/24 Technorati, Inc. 208.66.64.0/22 Technorati, Inc. I understand the AS entries correspond to the Internet provider, and the IP address ranges can be added to your firewall (I use CloudFlare service) whitelist.
