• 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.''

Probably the two most significant improvements in NetBSD 5.0 will be journalling for UFS (nore more fsck, yai!) and the move from XFree to X.org. Download now, or have a look at the changes in 5.0 if you need more reasons to check it out.

While talking about NetBSD 5, Izumi Tsutsui has updated his Restore CD for MIPS based Cobalt machines, see his email to the port-cobalt@ list for more details.

• Google Summer of Code is over for some time, but apparantly no final report has emerged so far (shame!). Still, a number of individual status reports came by on the official lists:
  • Zach Wegner's sysinst project
  • Adam Burkepile's subfile project (PDF)
  • Martin Schütte's syslogd project
  • Jeremy Morse's DVB project
  • Mark Dopiera's hurd translators project
  • Adam Hamsik's lvm project

  I know of at least one other project (uvc) that has completed but that I didn't see a report here - maybe I've missed it. Anyways, GSoC was another big success this year. Thanks, Google!

• Speaking of Adam Hamsik and Logical Volume Management (LVM), Adam has continued his work in that are, and he has written a device mapping library that interacts with his kernel driver. This allows to interact with his GSoC project without using any GPL code! See Adam's posting for more details.

• Force 10 Networks, producer of 10gbit switches that use an operating system based on NetBSD, have added a new feature as part of their FTOS operating system: VirtualView, which provides virtualization of Force 10 based equipment. From the xchange article: ``Force10 Networks Inc. this week introduced VirtualView software for benchmaking, troubleshooting and managing virtualized environments based on Force10 gear.''

  More information is available from the Force 10 Networks homepage, plus in articles by fibresystems.org, light reading, Zycko, and SmartBrief.

• Following the latest hype in portable computers, NetBSD has created a netbook page that intends to list models and the extent to which they are supported. Your contributions are most welcome here! (Contact me for sending updates and hardware :-)

• Zafer Aydogan has made RSS feeds available for CVS commits to single files - see his mail to netbsd-users for more details.

• New security advisory were released that I've missed in my last update:
  • NetBSD Security Advisory 2008-011: ICMPv6 MLD query
  • NetBSD Security Advisory 2008-012: Denial of service issues in racoon(8)

• A project that's been ongoing for quite some time is the move from "old-school" loadable kernel modules (LKMs) to new-style kernel modules. Important changes include the fact that modules can be either linked into the kernel at build time, or loaded into the kernel at runtime from the same file. Also, the bootloader was modified to load modules after the kernel, e.g. for a RAM-disk like the one that is used by the INSTALL kernel.

  In the same line, some parts are starting to be moved out of the GENERIC kernel, and installed as modules that can be loaded by the new framework then. The start is made by POSIX semaphores as a first step and proof-of concept, even if some details are still under hot debate, e.g. what the file system layout for modules is, and if the belong to the kernel and its build process, or to the userland.

• While talking about splitting the kernel into modules, Antti Kantee has continued his work to move parts of the kernel into userspace, in particular running file system code as userland in his RUMP, and puffs and (Re)FUSE works. The idea is to provide the interfaces that file systems need in the userland, and the result is that you can run code that used to run inside the kernel in userland now.

  Another subsystem running in the kernel that could be moved to userland by providing appropriate interfaces with the rest of the kernel is the network stack, and Antti has moved just that to the userland. See Antti's mail to tech-net@ for more information on this impressive work.

• NetBSD has shipped XFree in previous releases, and people who wanted to use X.org had to install it from pkgsrc. That's all fine, but to get a modern X, one had to compile things, as no precompiled binary packages are made available for many platforms. This is changing now, and NetBSD is getting X.org integrated via a reachover infrastructure which is also enabled for crosscompiling.

  The "user interface" for this is still in flux, but after some detour ("build.sh -V MKXORG=yes", without -x), "build.sh -x" now builds whatever X is considered the default for the platform. Some platforms already default to use X.org as X, and more will come, as changes that were made to NetBSD's copy of XFree are adopted to X.org.

  Platforms that use X.org by default now are macppc (see here and here), sparc sparc64, shark, amd64 and i386.

  As X.org is at Revision 7 now, it's installed in /usr/X11R7, which will lead to a lot of interesting effects. pkgsrc is already prepared for the new layout, but there are still many minor details that will need adjusting to the new directory. If you find one, post your patches to tech-x11.

• Besides the GNU C compiler, there's the BSD-licensed Portable C Compiler around for some time now. It doesn't offer the same support as its GNU cousin yet, but this may change now: The BSD Fund is currently doing a fund drive to get money to enhance PCC. The goal is to raise $12,000US to improve support for core compiler functionality as well as support for C99, gcc compatibility and the amd64 architecture. See the project page for further details.

• The NetBSD 5.0 release cycle has started! There's a netbsd-5 branch in CVS, daily binaries are available for testing, and some of the highlights of the upcoming release include file system journalling for FFS via WAPBL, and X.org.

  To help testing of NetBSD on Cobalt machines, Izumi Tsutsui has made a NetBSD 5.0_BETA based version of the Cobalt restore CD available. Enjoy!

• As the final point today, a word on NUMA support from Christoph Egger. Non-Uniform Memory Access is needed in massive parallel systems where some nodes have RAM more tightly associated than others, where the RAM is further away, resulting in different access times for different regions of memory. In order to support this, Christop Egger has made first steps.

  His example implementation uses information from ACPI, and shows some heavy dmesg-pr0n from a 16-core machine with four sockets. Yumm!

With some investigation, GNOME used pkgsrc's fontconfig goo, which doesn't include any fonts - which is about what it displays. To fix, /usr/pkg/etc/fontconfig/fonts.conf can be adjusted to also look in /usr/X11R6 (which I still have from my NetBSD 4.0 installation) and /usr/X11R7 (thanks to MKXORG=yes):

--- /usr/pkg/etc/fontconfig/fonts.conf.orig	2008-09-10 18:05:47.000000000 +0200

• In order to re-initialize x86 machines' video/VGA state after suspend and resume, some BIOS functions can be used. This needs to be done in real mode(?), which is a bit hard to do from an operating system kernel that runs in protected mode. To help doing so, a x86 CPU emulator was added to NetBSD some time ago, to help run VGA bios for ACPI resume. Now Joerg has added a sysctl that does just this, assuming your kernel has the VGA_POST options -- set machdep.acpi_vbios_reset=2

• Inside the kernel, data sent/received through the network stack is stored in chains of mbufs. So far, the mbufs were also used to store socket options, i.e. data describing further how the sending/receiving is done. This was split out into a separate struct sockopt by Ian 'plunky' Hibbert now. For more information, see sockopt(9).

• Hans 'woodstock' Rosenfeld has added a new accalerated driver for SPX graphics boards found in some VAXstations, which replaces the old and broken lcspx driver. The work is based on work by Blaz Antonic.

• The simonb-wapbl branch was merged: ``Add Wasabi System's WAPBL (Write Ahead Physical Block Logging) journaling code. Originally written by Darrin B. Jewell while at Wasabi and updated to -current by Antti Kantee, Andy Doran, Greg Oster and Simon Burge.'' This makes NetBSD the first second (see update below) BSD operating system that has a working file system with journaling (not counting LFS, which again and again has issues). Mmm, no more fsck! :-) See my other posts for more on journaling / wapbl.

  Update: James Mansion wrote me to that NetBSD's not the first BSD to have journaling, and I think he's right: DragonflyBSD's HAMMER file system apparently offers similar functionality: ``HAMMER implement an instant-mount capability and will recover information on a cluster-by-cluster basis as it is being accessed.''

• Accept filters were ported from FreeBSD by Coyote Point Systems, and integrated into NetBSD by Thor Lancelot Simon. What are accept filters? According to the accept_filter(9) manpage, they ``allow an application to request that the kernel pre-process incoming connections.'' Pre-defined filters are available with accf_data(9) and accf_http(9). The latter makes sure that the application's accept(2) call only sees the connection if there's a valid HTTP header, moving parts of the parsing from userland (httpd) to the kernel.

• Work is underway for crossbuilds of modular X.org. This is done via src/external/mit/xorg, which needs xsrc/external/mit. The results will be installed in /usr/X11R7(!). (XXX Where can I find more about this?)

• Gregory McGarry is working to get the tree compiled with PCC instead of GCC. This is still ongoing.

• nvi was updated from version 1.79 to 1.81. The most important part of this update is that internationalization is now handled by default.

• Following a bigger masterplan, new 3rd party software packages are now imported into src/external/${license}, which will replace src/dist, src/crypto/dist and src/gnu/dist in the long run. Packages will be moved on upgrades only, existing packages are not being moved just for the sake of moving them.

• Adam Hamsik is working on getting Logical Volume Management (LVM) going in NetBSD. He has adapted Linux' "device mapper" kernel-interface as part of his Google Summer-of-Code project, and with the help of the (GPL'd) Linux tools, things are looking pretty good. More on this in a separate post. This work is currently happening on the haad-dm branch.

• In the context of his work on UDF, Reinoud has added routines for speeding up directory handling by using hash gables. Lookup of files was O(n*n) and is now O(1) even for file creation. See my other blog posting for details and impressive numbers.

• Perry Metzger is working to make binary builds identical. This is useful for binary diffs between releases/builds, e.g. when providing binary patches for updates and security fixes. Areas where this had an impact on are C++ programs and various bootloaders (which had a builder, build date, etc. in it so far).

• EHCI (USB) can now do high speed isochronous support. This was developed by Jeremy Morse as part of his Google Summer-of-Code "dvb" project this year, it is useful for fast transfer of data that comes in steady streams, e.g. from video cards.

• fsck_ffs(8) now has options -x and -X (just like dump) that create a file system snapshot via fss(4), and then operates on the snapshot. This allows "fsck_ffs -n" to work on a snapshot of a read/write mounted file system, and avoid errors related to file system activity. Can be made permanent for the nightly script by setting run_fsck_flags="-X" in /etc/daily.conf. This was brought to you by our Xen-hacker Manuel Bouyer. :-)
