[20100119] A colorful collection of NetBSD news from the past few weeks
AKA "I've been slacking again, and there's a whole pile of stuff here now that I'm putthing into one blog posting". Here we go:
  • Initial support for the FriendlyArm Mini2440 board has been announced by Paul Fleischer. In a later update, most of the hardware is reported working, and the patch is available for review & comments. Furthermore, the touch screen is usable, and Qt/Embedded was built on top of wscons.

  • Force10 Networks Receives Common Criteria Security Certification for Its High-Performance Ethernet Switch/Router Products. According to the article, ``Common Criteria evaluations entail formal rigorous analysis and testing to examine security aspects of a product or system. Extensive testing activities involve a comprehensive and formally repeatable process, confirming that the security product functions as claimed by the manufacturer. Security weaknesses and potential vulnerabilities are specifically examined during wide-ranging evaluation and testing.

    FTOS is the operating system software that runs on Force10 switch/router product lines, including the E-Series, C-Series and S-Series platforms. Based on NetBSD, FTOS leverages a distributed, multiprocessor architecture that delivers highly scalable protocols and reliability. By delivering the same OS across its entire switch/router line, Force10 ensures that customers benefit from stable code, a consistent configuration environment and simpler software management. ''

  • While there: Force10 Networks Delivers Ethernet-Optimized Platform for MPLS Core Networks: ``Force10 Networks, Inc. [...] announced the immediate availability of MPLS (multi-protocol label switching) functionality for its ExaScale E-Series core switch/routers. [...] The ExaScale platform combines high-density, non-blocking, line-rate 10 GbE switching and routing with robust MPLS LSR support at 1/5th of the cost of a traditional core router, enabling carriers to fully capitalize on the economic advantages of Ethernet.''

  • Create Bootable Live Linux USB Drives with UNetbootin: ``UNetbootin allows you to create bootable Live USB drives for a variety of Linux distributions from Windows or Linux, without requiring you to burn a CD. You can either let it download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list.''

    And of course we all know that NetBSD is Linux, right? See the list of supported distributions:

    The homepage mentions that NetBSD 4.0 is supported, maybe someone wants to give them an update on what's up with NetBSD 5.0? Would be nice to see that on the list!

  • Ever wondered what happened with the BSD Certification recently? There's a video from the talk BSD Certification Group: A Case Study in Open Source Certification available that talks about the goal of the project, the two exams (BSD Associate, BSD Professional), and what's going on behind the scenes.

  • With the move from XFree to X.org, the X server for the DNARD Shark's NetBSD/shark lost support for accelerated X. Thanks to Michael 'macallan' Lorenz, hardware-accelerated X for NetBSD/shark is back now: ``I finally got around to start working on an Xorg driver for the IGS CyberPro 20x0 family found in rev. 5 Sharks, Netwinder etc. - currently the driver is built only on shark and supports only the VL variant found there. Adding support for PCI chips is trivial though, just needs extra probing. The driver supports autoconfiguration ( X -configure should yield something almost usable, only DefaultDepth needs to be adjusted).''

  • Staying with cool platforms, here's a quick procedure to run NetBSD/sun2 5.0.1 on The Machine Emulator (TME) (see pkgsrc/emulators/tme), compiled by Izumi Tsutsui. Who's first do get a pkgsrc bulk build done? :-)

  • Jed Davis has committed the RAIDframe parity Summer-of-Code project. See his posting for the details. The project ``drastically reduces the time RAIDframe spends rewriting parity after an unclean shutdown by keeping better track of outstanding writes (thus, "parity map"). The tech-kern archives have more details [...]

    This feature is enabled by default on all sets (other than RAID 0). It can be administratively disabled with the new "raidctl -M" flag, which is described in the changes to the raidctl(8) man page; however, the I/O overhead for updating the parity map is expected to be unnoticeable in practice.''

So much for now. There is more in the pipe, but that will have to wait for now. Good night!

[20060529] Ayame MPLS stack ported to NetBSD
Multiprotocol Label Switching (MPLS) is supposed to speed up packet forwarding in routers by simplifying the decisions of where to forward the packet to. Rui Paulo has been porting the in-kernel MPLS support of the Ayame MPLS stack to NetBSD-current. See Rui's mail to tech-net for more information, or look at his patch directly.

Information on MPLS is available in Wikipedia, the Multiprotocol Label Switching Architecture is defined in RFC 3031.

One open question that remains to be answered is how the Ayame implementation compares to Mihai 'kefren' Chelaru's implementation.

[20060301] MPLS status
Mihai 'kefren' Chelaru has been working on bringing Multi-Protocol Label Switching (MPLS) to NetBSD. After some reports in his blog, he has posted to the tech-net mailing list about the state of affairs. The most recent work on LDP etc. can be found on Sourceforge and on kefren's website.
