    <title>Introduction</title>

    <p>This report covers FreeBSD related projects between June and
    October 2006. This includes the conclusion of this year's Google
    Summer of Code with 13 successful students. Some of last year's and
    the current SoC participants have meanwhile joined the committer
    ranks, kept working on their projects, and improving FreeBSD in
    general.</p>

    <p>This year's
    <a href="http://www.eurobsdcon.org/">EuroBSDCon</a>

    in Milan, Italy has meanwhile published an exciting program. Many
    developers will be there to discuss these current and future projects
    at the Developer Summit prior the conference. Next year's
    conference calendar has a new entry - in addition to the now well
    established
    <a href="http://www.bsdcan.org/">BSDCan</a>

    in Ottawa -
    <a href="http://www.asiabsdcon.org/">AsiaBSDCon</a>

    will take place in Tokyo at the beginning of March.</p>

    <p>As we are closing in on FreeBSD 6.2 release many bugs are being
    fixed and new features have been MFCed. On the other hand a lot of
    the projects below already are focusing on FreeBSD 7.0 and promise
    a lot of exciting news and features to come.</p>

    <p>Thanks to all the reporters for the excellent work! We hope you
    enjoy reading.</p>

      <p>Most dhclient changes in HEAD have been merged to 6-STABLE for
      6.2-RELEASE. The highlight of these changes is a fix for runaway
      dhclient processes when packets are not 4 byte aligned. Further
      changes including always sending client identifiers are scheduled
      for merge before the release. Work is ongoing to improve dhclient's
      interaction with alternate methods of setting interface
      addresses.</p>

      <p>The FreeBSD/arm port has grown support for the Atmel AT91RM9200.
      Boards based on this machine are booting to multiuser off either
      NFS or an SD card. The onboard serial ports, PIO, ethernet and
      SD/MMC card controllers are well supported. Support for the SSC,
      IIC and SPI flash parts in the kernel will be forthcoming
      shortly.</p>

      <p>In addition to normal kernel support, the port includes a boot
      loader that can initialize memory and boot off IIC eeprom, SPI
      DataFlash, BOOTP/TFTP and SD memory cards.</p>

      <p>The port will be included in forthcoming commercial

      <p>We had another successful summer taking part in the Google
      Summer of Code. By all accounts, the FreeBSD participation in this
      program was an unqualified success. We received over 150
      applications for student projects, amongst which 13 were selected
      for funding. All successful students received the full $4,500.</p>

      <p>These student projects included security research, improved
      installation tools, new utilities, and more. Many of the students
      have continued working on their FreeBSD projects even after the
      official close of the program. At least 2 of our FreeBSD mentors
      will be meeting with Google organizers in Mountain View this month
      to discuss the program at the Mentor Summit.</p>

      <p>The FreeBSD Release Engineering team is currently working on
      FreeBSD 6.2-RELEASE, which is scheduled for release in early
      November 2006. Some notable features of this release include the
      debut of security event auditing as an experimental feature, Xbox
      support, the FreeBSD Update binary updating utility, and of course
      many fixes and updates for existing programs. Pre-release images
      for all Tier-1 architectures are available for testing now;
      feedback on these builds is greatly appreciated. More information

      <p>The focus of this project was to review past vulnerabilities,
      create vulnerability testing tools and to discover new
      vulnerabilities in the FreeBSD IPv6 stack which is derived from the
      KAME project code. During the summer Clement took two libraries,
      the popular libnet, and his mentor's Packet Construction Set (PCS)
      and created tools to find security problems in the IPv6 code.
      Several issues were found, bugs filed, and patches created. At the
      moment Clement and George are editing a 50 page paper that
      describes the project which will be submitted for conference
      publication.</p>

      <p>All of the code from the project, including the tools, is
      online and is described in the paper.</p>

      <p>By all measures, this was a successful project. Both student and
      mentor gained valuable insight into a previously externally
      maintained set of code. In addition to the new tools development in
      this effort, the FreeBSD Project has gained a new developer to help
      work on the code.</p>

      Wiki</url>
    </links>

    <body>
      <p>This project consisted in the improvement of the Interrupt
      Handling System in FreeBSD: while retaining backward compatibility
      with the previous models (FAST and ITHREAD), a new method called
      'Interrupt filtering' was added. With interrupt filtering, the
      interrupt handler is divided into 2 parts: the filter (that checks
      if the actual interrupt belong to this device) and the ithread
      (that is scheduled in case some blocking work has to be done). The
      main benefits of interrupt filtering are:</p>

      <ul>
        <li>Feedback from filters (the system finally knows if any
        handler has serviced an interrupt or not, and can react
        consequently).</li>

        <li>Lower latency/overhead for shared interrupt line.</li>

        <li>Previous experiments with interrupt filtering showed an
        increase in performance against the plain ithread model</li>
      </ul>

      <p>Moreover, during the development of interrupt filtering, some MD
      dependent code was converted into MI code, PPC was fixed to support
      multiple FAST handlers per line and an interrupt stray storm
      detection logic was added. While the framework is done, there are
      still machine dependent bits to be written (the support for ppc,
      sparc64, arm and itanium has to be written/reviewed) and a serious
      analysis of the performance of this model against the previous one
      is a work-in-progress</p>

      <p>For me, the Google Summer of Code was a new and very exciting
      experience. I got actively involved in doing Open Source Software
      and giving something back to the community. Facing some
      challenges within the project forced me to look behind the scenery
      of FreeBSD. The result was a better understanding of the overall
      project. Working with a lot of developers directly also
      gave a very special spirit to the Google Summer of Code.</p>

      <p>I really enjoyed the time and will continue to work on the
      project after the deadline. For me, it was a great chance to get
      involved in active development and not just some scripts and hacks
      at home. Getting paid for the work was just a small part of the
      overall feeling.</p>

      <p>Thanks to the people at the FreeBSD Project and Google for the
      really, really great time!</p>

      Detailed Description of the Completed Project</url>
    </links>

    <body>
      <p>The Project consisted of five parts:</p>

      <ol>
        <li>Nsswitch modules and libc separation. The idea was to move
        the source code for different nsswitch sources (such as "files",
        "dns", "nis") out of the libc into the separate shared libraries.
        This task was successfully finished and the patch is
        available.</li>

        <li>Regression tests for nsswitch. A set of regression tests to
        test the correctness of all nsswitch-related functions and the
        invariance of their behavior between system upgrades. The task
        can be considered successfully completed, the patch is
        available.</li>

        <li>Rewriting nss_ldap. Though, this task was not clearly
        mentioned in the original proposal, during the SoC we found
        it would be easier, not to simply import PADL's nss_ldap, but
	to rewrite it from scratch (licensing issues were among the
	basic reasons for this). The resulting module behaves similarly
	to PADL's module, but has a different architecture that is more
	flexible.  Though it's basically finished, several useful
	features from the PADL's nss_ldap still need to be implemented.
	Despite the lack of some features, this task can be considered
	successfully completed. Missing features will be implemented as
	soon as possible, hopefully during September.</li>

        <li>Importing nss_ldap into the Base System. The task was to
        prepare a patch, that will allow users to use nss_ldap from the
        base system. The task was successfully completed (the patch is
        available), but required importing OpenLDAP into the base in
        order for nss_ldap to work properly, and it had led to a long
        discussion in the mailing list. This discussion, however, have
        concluded with mostly positive opinions about nss_ldap and
        OpenLDAP importing.</li>

        <li>Cached performance optimization. The caching daemon
        performance needs to be as high as possible in order for cached
        to be as close (in terms of speed) to "files" nsswitch source as
        possible. Cached's performance analysis was made and nsswitch
        database pre-caching was introduced as the optimization. This
        task was completed (the patch is available). However there is
        room for improvement. More precise and extensive performance
        analysis should be made and more optimizations need to be
        introduces. This will be done in the near future.</li>
      </ol>

      <p>Though none of the code was committed yet into the official
      FreeBSD tree, my experience from the previous year makes me think
      that this situation is normal. I hope, that the code will be
      reviewed and committed in the coming months.</p>

      <p>Dongmei Liu spent the summer working on the basic footwork
      required to port the SEREF policy to SEBSD. This work has been
      submitted and can be viewed in the soc2006/dongmei_sebsd Perforce

      Giant, but most have been brought out of Giant. At the moment I am
      looking for testers that can test the various USB device drivers.
      Some have already been tested, and confirmed to work, while others
      have problems which need to be fixed. If you want to test, checkout
      the USB perforce tree or download the SVN version of the USB driver
      that is available on my homepage. At the moment the tarballs are a

      supported releases are listed on the web site; of particular note,
      FreeBSD 5.3 and FreeBSD 5.4 will cease to be supported at the end
      of October 2006, while FreeBSD 6.0 will cease to be supported at

      <p>My work is moving slowly forward. ZVOL is, I believe, fully
      functional (I recently fixed snapshots and clones on zvols), which
      means you can put UFS on top of RAID-Z volume, take a snapshot of
      the volume, clone it if needed, etc. Very cool. The hardest part is
      the ZPL layer, I'm still working on it. Most file system methods
      work, but probably need detailed review and many fixes. Most of the
      time these days I'm spending on implementing mmap(2) correctly. It
      works more or less in simple tests but fails under fsx program. On
      the other hand, 'fsx -RW' works very stable and reliable. Other
      test programs (those that don't use mmap(2)) also work quite well.
      There is still a lot of work to do, mostly in ZPL area, many
      clean-ups, etc. Some functionality (like ACLs) I haven't even tried
      to touch yet.</p>

      <p>TSO - TCP Segmentation Offload support has been committed to the
      network stack of FreeBSD-current in September 2006. With TSO, TCP
      can send data in the send socket buffer in bulk down to the network
      card which then does the splitting into MTU sized packets. On bulk
      high speed sending the performance is increased by 25% (normal
      writes) to 108% (sendfile). Jack Vogel and Prafulla Deuskar of
      Intel committed the driver changes for TSO hardware support of
      em(4) based network cards.</p>

      <p>These changes are scheduled to be backported to FreeBSD 6-STABLE
      shortly after FreeBSD 6.2-RELEASE is published to appear in

    </links>

    <body>
      <p>The addition of TSO (TCP Segmentation Offload) has highlighted
      some shortcomings in the sendfile(2) and sosend_*() kernel
      implementations.</p>

      <p>The current sendfile(2) code simply loops over the file, turns
      each 4K page into an mbuf and sends it off. This has the effect
      that TSO can only generate 2 packets per send instead of up to 44
      at its maximum of 64K. kern_sendfile() has been rewritten to work
      in two loops, the inner which turns as many pages into mbufs as it
      can -- up to the free send socket buffer space. The outer loop then
      drops the whole mbuf chain into the send socket buffer, calls
      tcp_output() on it and then waits until 50% of the socket buffer
      are free again to repeat the cycle. This way tcp_output() gets the
      full amount of data to work with and can issue up to 64K sends for
      TSO to chop up in the network adapter without using any CPU cycles.
      Thus it gets very efficient especially with the readahead the VM
      and I/O system do.</p>

      <p>Looking at the benchmarks we see some very nice improvements:
      181% faster with new sendfile vs. old sendfile (non-TSO), 570%
      faster with new sendfile vs. old sendfile (TSO).</p>

      <p>The current sosend_*() code uses a sosend_copyin() function that
      loops over the supplied struct uio and does interleaved mbuf
      allocations and uiomove() calls. m_getm() has been rewritten to be
      simpler and to allocate PAGE_SIZE sized jumbo mbuf clusters (4k on
      most architectures). m_uiotombuf() has been rewritten to use the
      new m_getm() to obtain all mbuf space in one go. It then loops over
      it and copies the data into the mbufs by using uiomove().
      sosend_dgram() and sosend_generic() have been changed to use
      m_uiotombuf() instead of sosend_copyin().</p>

      <p>Looking at the benchmarks we see some very nice improvements:
      290% faster with new sosend vs. old sosend (non-TSO), 280% faster
      with new sosend vs. old sosend (TSO).</p>

      <p>Newly written is a specific soreceive_stream() function for
      stream protocols (primarily TCP) that does only one socket buffer
      lock per socket read instead of one per data mbuf copied to
      userland. When doing netperf tests with WITNESS (full lock tracking
      and validation enabled) the receive performance increases from
      ~360Mbit/s to ~520Mbit/s. Without WITNESS I could not measure any
      statistically significant improvement on a otherwise unloaded
      machine. The reason is two-fold: 1) per packet we do a wakeup and
      readv() is pretty much as many times as packets come it, thus the
      general overhead dominates; 2) the packet input path has a pretty
      high overhead too. On heavily loaded machines which do a lot of
      high speed receives a performance increase should be
      measureable.</p>

      <p>The patches are scheduled to be committed to FreeBSD-current at
      end of October or early November 2006.</p>

      <p>This work was sponsored by the TCP/IP Optimization Fundraiser

      <p>The ports PRs surged (especially due to a large number of new
      port submissions), but with some hard work we have been able to get
      back down to around 900. We are rapidly approaching 16,000
      ports.</p>

      <p>Due to this acceleration in adding new ports, portmgr is now
      very concerned that we are outstripping the capacity of both the
      build infrastructure and our volunteers to keep up with build
      errors and port updates. Accordingly, we've added a guideline (not
      a rule) that ports should be of more than just theoretical use to
      be added to the Ports Collection (e.g. we can't support all of CPAN
      + all of Sourceforge + everything else). Basically, use common
      sense as a guideline; certainly no one wants to see any kind of
      "gateway" procedure to get incoming ports approved.</p>

      <p>Seven sets of changes have been added to the infrastructure,
      mostly refactoring and bugfixing.</p>

      <p>As part of a Summer of Code project, we have also incorporated
      some of gabor@'s changes to incorporate better DESTDIR support.
      However, due to some unanticipated side-effects, more work is going
      to be needed in this area. gabor@ is continuing to work on the
      changes.</p>

      <p>netchild@ and bsam@ have been doing a great deal of work to
      bring the linux emulator ports closer to sanity, including bringing
      up a regression-test suite.</p>

      <p>The long-anticipated import of X.Org 7 has stalled due to
      developer time, mostly to deal with documentation and upgrade
      instructions. Hopefully this can get done in the early 6.3
      development cycle. See the wiki for more information.</p>

      <p>As a part of that work, the decision has been made to move away
      from using X11BASE and just put everything into LOCALBASE;
      /usr/X11R6 is simply an artifact at this point. A plan for a
      transition process is underway; a great deal of testing will need
      to be done, but in the end the ports tree will be much cleaner. The
      GNOME team has already done the work to move all of their ports
      over, and it will be incorporated after the 6.2 release is
      shipped.</p>

      <p>tmclaugh@ is looking for someone to take over the C# ports. He
      has maintained them for over a year and wants more time to be able
      to work on other projects.</p>

      <p>Some work has been done to get rid of FreeBSD 2.X cruft in
      ports. Further work is needed to get the 3.X cruft removed.</p>

      <p>linimon@ did another pass through resetting inactive
      maintainers. Another list is waiting in the wings.</p>

      <p>linimon@ is also working on adding the ability for portsmon to
      analyze successful packages (not just failed ones), so that queries
      such as "show me packages that build on i386 but not amd64" and
      "show me why dependent package foo was not built on bar". This is
      currently in alpha testing.</p>

      <p>We have added 4 new committers since the last report.</p>
    </body>

    <help>
      <task>We still need help getting back to our modern low of 500
      PRs.</task>

      <task>We have nearly 4400 unmaintained ports (see, for instance,
      <url
      href="http://portsmon.freebsd.org/portsconcordanceformaintainer.py?maintainer=ports@FreeBSD.org">
      the list on portsmon</url>

      ). Although there has been a welcome upsurge in new maintainers
      recently which has dropped the percentage down below 28%, we still
      need much more help.</task>

      <task>A test run of gcc4.1 on the ports tree showed around 1000 new
      build errors. Kris@ has posted some results so that people can
      start working on the problems now. In particular, it seems that
      certain older versions of GCC cannot be built with GCC 4.1, so
      ports that depend on those older versions are going to have to be
      fixed as well. Although the import of GCC 4.1 to -CURRENT is not
      imminent, the time to start planning is now.</task>

      <task>The state of the packages on AMD64 and sparc64 significantly
      lags that of i386. In many of these cases, packages are not
      attempted because NOT_FOR_ARCH is used instead of more accurately
      only setting BROKEN based on ARCH. (pointyhat can be forced to
      build packages that are marked BROKEN, but not NOT_FOR_ARCH).
      NOT_FOR_ARCH is supposed to denote only "will never work on this
      ARCH". Although we have volunteers who have expressed interest in
      sparc64 (and ia64), we need more people who are running amd64
      (especially as a desktop) to help us get more packages
      working.</task>

        <p>The TrustedBSD audit implementation provides fine-grained
        security event logging throughout the FreeBSD operating system.
        The big news for the last quarter is that the TrustedBSD audit
        implementation has been merged into RELENG_6 branch, and appeared
        in 6.2-BETA2. Over the past few months, work has also occurred in
        the following areas:</p>

        <ul>
          <li>OpenBSM 1.0 alpha 8 through alpha 12 have been released and
          merged into FreeBSD CVS. Changes include significant numbers of
          bug fixes, documentation improvements, and feature
          enhancements. These include regular expression based matching
          for auditreduce, auditd management of kernel audit policy (such
          as maximum trail file size), improvements in printing support
          for a variety of tokens including execve argument support.</li>

          <li>Significant enhancements to the FreeBSD Handbook chapter on
          Audit.</li>

          <li>Full audit support for execve events, including optional
          auditing of command line arguments and environmental variables,
          as well as audit support for a broad range of other additional
          kernel events.</li>

          <li>Kqueue support for audit pipes.</li>

          <li>Robustness improvements in the presence of low disk space
          conditions.</li>

          <li>Support for system call capture on additional platforms,
          such as ppc and ia64.</li>

          <li>Improved support for very large audit record sizes (as
          required for extensive execve support).</li>

          <li>id(1) now supports a -A argument to query audit state for
          the process.</li>

          <li>An audit_warn(5) event for trail rotation, which can be
          used for archiving, reduction, and other administrative
          activities.</li>
        </ul>

        <p>Lots of testing as part of the 6.2-BETA cycle would be much
        appreciated. Audit support will be considered an experimental
        feature in FreeBSD 6.2-RELEASE, but we hope that it will be a
        production feature in 6.3-RELEASE.</p>

      <p>The MMC/SD stack got a significant boost this quarter. Warner
      Losh and Bernd Walter have written a generic MMC/SD flash card
      stack for FreeBSD, and have implemented a host controller for the
      AT91RM9200 embedded ARM controller they are each using in separate
      projects.</p>

      <p>The stack is presently experimental in quality. It is being used
      as the root file system for these embedded projects. There's been
      no work done to support hot insertion and removal of cards (neither
      board wires up the pins necessary, and besides, / disappearing is
      very bad). There are still many rough edges.</p>

      <p>This is a freshly written stack. It has been written using the
      SD 1.0 (and recently 2.0) simplified specification, with the
      SanDisk MMC application notes supplementing. The Linux stack looks
      good, although not entirely standards conforming (there's work in
      progress that I've not seen that is supposed to fix this) and it
      is contaminated with the GPL. The OpenBSD stack also looks
      interesting, but Warner's experience porting NEWCARD over from
      NetBSD suggested that a fresh rewrite may be faster, at least for
      the bus and driver level. Since MMC is fairly simple, a port of the
      sdhci driver might be possible.</p>

      <p>FreeSBIE is a FreeBSD based LiveCD.</p>

      <p>On August 19th, Matteo Riondato, a member of the FreeSBIE staff,
      released an unofficial ISO, codename FreeSBIE GMV, based on FreeBSD
      -CURRENT (read the Announcement to download it). This is supposed
      to be the first in a series of four ISOs that will end up with the
      release of FreeSBIE 2.0. Matteo is now working on another ISO,
      codename FreeSBIE LVC, which is scheduled to be released October 12th.</p>

      <p>FreeSBIE 2.0 will be based on FreeBSD 6.2-RELEASE and will
      hopefully be released at EuroBSDCon 2006 in Milan. It will be
      available for the i386 and AMD64 platforms.</p>

    <body>
      <p>Roman Divacky participated in the Google Summer of Code 2006 and
      implemented a major part of the syscall compatibility to the 2.6.16
      Linux kernel. The work has been committed to -CURRENT (the default
      compatibility still being a 2.4.2 Linux kernel) and we are working
      on fixing the remaining bugs as time permits.</p>

      <p>"Intron" submitted an implementation for the linux aio syscalls.
      His work has been committed to the Perforce repository.</p>

      <p>We also started to consolidate a list of known bugs, open issues
      and helpful stuff (e.g. regression tests and their status) in
      -CURRENT on a page in the FreeBSD wiki (see the links-section). It
      also contains a link to a more or less up-to-date patch with stuff
      we have in the Perforce repository so that interested people can
      help with testing. Thanks to the help of Marcin Cieslak we already
      fixed some bugs (some of the fixes are already MFCed to
      -STABLE).</p>

      <p>Thanks to the nice regression tests of the Linux Test Project
      (LTP) we have a list of small (and not so small) things which need
      to be looked at. This list makes up for a quick start into kernel
      hacking. So if you have a little bit of knowledge about C
      programming, and if you want to help us a little bit in improving
      FreeBSD, feel free to have a look at the list and to try to fix a
      problem or two. Sometimes it is as easy as "if (error condition)
      return Esomething;" (but you should coordinate with the emulation
      mailinglist, so that nobody does some work someone else just did
      too). Even if you do not know how to program, you can help. Have a
      look at the wiki page and tell us about things which should get
      mentioned there too. Or download the patch and test it.</p>

      <p>Since the last status report we added basic support for envy24ht
      chips, imported the emu10kx driver into the base system and added
      support for High Definition Audio (HDA) compatible chips.</p>

      <p>Additionally the work of Ryan Beasley as part of his Google
      Summer of Code 2006 participation is committed. It adds
      compatibility to the Open Sound System (OSS) v4 API as far as this
      was possible. This allows for more sophisticated programs to be
      written. For example it is now possible to synchronize the start of
      multiple sound channels. It is also possible for a driver to
      support more than the AC97 mixer devices, but so far no driver has
      been extended to support this yet. More about it can be found in
      the wiki and in the official OSS documentation.</p>

      <p>The wiki page about the sound system was started to describe
      the current status of the sound system and to provide some
      information about where we are heading. But more work needs to be
      done to reach this goal. So far we collected some information about
      the status of the most recent work in the soundsystem. So if you
      have a look at it and you think that something important is
      missing, just tell us about it. While fully prepared content is
      very welcome, we are even happy about some ideas what we should
      list on the wiki page.</p>

      Protocol (RSTP) which supersedes Spanning Tree Protocol (STP).
      RSTP has a much faster link failover time of around one second

      <p>There were a number of OCaml ports in our tree, and each of them

      task of OCaml-language ports creation, the special framework
      (bsd.ocamk.mk) was developed and most of the ports were converted to
      use this framework. This allowed a lot of duplicate code to be
      removed. This new framework handles all the things required to
      install an OCaml-language library and properly register it.
      bsd.ocaml.mk also contains knobs to deal with findlib-powered
      libraries, modify ld.conf in the proper way, etc. Also, a lot of
      new Ocaml-related ports were added.</p>

      <p>Last month I was working on a driver/module to update the
      microcode of Intel or AMD CPUs that support having their
      microcode updated. As you might know these processors are
      microcode-driven and this firmware can be updated. Intel(R)
      often releases microcode updates, and AMD(R) updates can be
      found in BIOS programs. The work is almost finished now, I just
      need to find a bit of time to test it on AMD64 systems and
      perform some code cleanup. The driver also provide a way for
      userland programs to access the Machine Specific Registers (MSR)
      and CPUID info for a certain cpu. This will allow some programs
      like x86info to provide more accurate information about cpus in
      SMP systems and make assumptions based on the contents of the
      MSR.</p>

      <p>During the Google Summer of Code 2006, Gábor worked on several
      ideas to improve the ports infrastructure:</p>

      <ol>
        <li>New handling for i386 binary ports.</li>

        <li>Cleanup: use ECHO_CMD and ECHO_MSG in bsd.port.mk
        properly.</li>

        <li>Add basic infrastructure support for debugging.</li>

        <li>Installing ports with different destination (DESTDIR
        macro).</li>

        <li>Cleanup: Move fetch shell scripts out of bsd.port.mk.</li>

        <li>Make ports respect CC and CFLAGS.</li>

        <li>Cross-compiling Ports.</li>

        <li>Plist generator tool.</li>
      </ol>

      <p>The first three items have been completed and the next two
      items are being worked on. The DESTDIR support was more
      complicated than presumed and took more time than expected to
      complete.  Gábor will continue working to finish these tasks and
      other ports related tasks. FreeBSD is happy to have interested
      him to keep working on ports and ports infrastructure.</p>

      <p>I thought that since I sent a status report the last time, I
      might as well send one now.</p>

      <p>Since the last status report I have done work on several of the
      remaining commands as attach, detach, and finally the concat
      command to be able to create concatenated volumes with one easy
      command. The mirror and stripe commands are the next step after
      this.</p>

      <p>The most important thing I've been working on is maybe the
      implementation of drivegroups. I have posted a bit information on
      this mailinglists, but basically, it's a way to group drives with
      the same configuration. This way, you can make many commands
      operate on groups instead of drives, and the group-abstraction will
      handle how the underlying subdisks are created on the drives.
      In the future one will be able to move groups to different
      machines, etc.</p>

      <p>I've created a patch of all my work that is not in HEAD yet here
      (this is a snapshot of my development branch, so how thing's are
      done might be changed quite fast):

      these drives at very good prices. The server will be deployed in
      the next few weeks.</p>

      <p>The FreeBSD Foundation continued to support the FreeBSD project
      and community through various activities. These activities include
      creating strategies for fund development and actively seeking
      funding for the FreeBSD community, coordinating a new IBM
      Bladeserver project, and protecting the image and integrity of
      FreeBSD by governing the use of the trademarks. We are pleased to
      be a sponsor of EuroBSDCon and will be sponsoring a few developers
      to attend the conference through our travel grant program. And
      finally, we have secured funds for a major project that will be
      announced later this month.</p>
