    <title>Introduction</title>

    <p>The FreeBSD status report is back again after another small break.  The
    second half of 2004 was incredibly busy; FreeBSD 5.3 was released, the
    6-CURRENT development branch started, and EuroBSDCon 2004 was a huge
    success, just to name a few events.  This report is packed with an
    impressive 44 submissions, the most of any report ever!</p>

    <p>It's also my pleasure to welcome Max Laier and Tom Rhodes to the status
    report team.  They kindly volunteered to help keep the reports on time
    and help improve their quality.  Max in particular is responsible for
    the reports being divided up into topics for easier browsing.  Many
    thanks to both for their help!</p>

      <p>Currently TCP segment reassembly is implemented as a linked list
      of segments. With today's high bandwidth links and large
      bandwidth*delay products this doesn't scale and perform well.</p>

      <p>The rewrite optimizes a large number of operational aspects of
      the segments reassembly process. For example it is very likely that
      the just arrived segment attaches to the end of the reassembly
      queue, so we check that first. Second we check if it is the missing
      segment or alternatively attaches to the start of the reassembly
      queue. Third consecutive segments are merged together (logically)
      and are skipped over in one jump for linear searches instead of
      each segment at a time.</p>

      <p>Further optimizations prototyped merge consecutive segments on
      the mbuf level instead of only logically. This is expected to give
      another significant performance gain. The new reassembly queue is
      tracking all holes in the queue and it may be beneficial to
      integrate this with the scratch pad of SACK in the future.</p>

      <p>Andrew Gallatin was able to get 3.7Gb/sec TCP performance on
      dual-2Gbit Myrinet cards with severe packet reordering (due to a
      firmware bug) with the new TCP reassembly code. See second

      <p>The old TTCP according to RFC1644 was insecure, intrusive,
      complicated and has been removed from FreeBSD &gt;= 5.3. Although
      the idea and semantics behind it are still sound and valid.</p>

      <p>The rewrite uses a much easier and more secure system with 24bit
      long client and server cookies which are transported in the TCP
      options. Client cookies protect against various kinds of blind
      injection attacks and can be used as well to generally secure TCP
      sessions (for BGP for example). Server cookies are only exchanged
      during the SYN-SYN/ACK phase and allow a server to ensure that it
      has communicated with this particular client before. The first
      connection is always performing a 3WHS and assigning a server
      cookie to a client. Subsequent connections can send the cookie back
      to the server and short-cut the 3WHS to SYN-&gt;OPEN on the
      server.</p>

      <p>TTCPv2 is fully configurable per-socket via the setsockopt()
      system call. Clients and server not capable of TTCPv2 remain fully
      compatible and just continue using the normal 3WHS without any
      delay or other complications.</p>

      <p>Work on implementing TTCPv2 is done to 90% and expected to be
      available by early February 2005. Writing the implementation
      specification (RFC Draft) has just started.</p>

    <body>
      <p>Modern CPU's can only perform to their maximum if their working
      code is in fast L1-3 cache memory instead of the bulk main memory.
      All of today's CPU's support certain L1-3 cache prefetching
      instructions which cause data to be retrieved from main memory to
      the cache ahead of the time that it is already in place when it is
      eventually accessed by the CPU.</p>

      <p>CPU Cache Prefetching however is not a golden bullet and has to
      be used with extreme care and only in very specific places to be
      beneficial. Incorrect usage can lead to massive cache pollution and
      a drop in effective performance. Correct and very carefully usage
      on the other can lead to drastic performance increases in common
      operations.</p>

      <p>In the linked patch CPU cache prefetching has been used to
      prefetch the packet header (OSI layer 2 to 4) into the CPU caches
      right after entering into the network stack. This avoids a complete
      CPU stall on the first access to the packet header because packets
      get DMA'd into main memory and thus never are already pre-cache in
      the CPU caches. A second use in the patch is in the TCP input code
      to prefetch the entire struct tcpcb which is very large and used
      with a very high probability. Use in both of these places show a
      very significant performance gain but not yet fully quantified.</p>

      <p>The final patch will include documentation and a guide to
      evaluate and assess the use of CPU cache prefetch instructions in
      the kernel.</p>

      <p>The TCP code in FreeBSD has evolved significantly since the fork
      from 4.4BSD-Lite2 in 1994 primarily due to new features and
      refinements of the TCP specifications.</p>

      <p>The TCP code now needs a general overhaul, streamlining a
      cleanup to make it easily comprehensible, maintainable and
      extensible again. In addition there are many little optimizations
      that can be done during such an operation propelling FreeBSD back
      at the top of the best performing TCP/IP stacks again, a position
      it has held for the longest time in the 90's.</p>

      <p>This overhaul is a very involved and delicate matter and needs
      extensive formal and actual testing to ensure no regressions
      compared to the current code. The effort needed for this work is
      about two man-month of fully focused and dedicated time. To get it
      done I need funding to take time off my day job and to dedicate me
      to FreeBSD work much the way PHK did with his buffer cache and

      <p>The ARP IP address to MAC address mapping does not belong into
      the routing table (FIB) as it is currently done. This will move it
      to its own hash based structure which will be instantiated per each

      more than one interface in the same IP subnet and layer 2 broadcast
      domain. The ARP handling and the routing table will be quite a bit
      simplified afterwards. As an additional benefit full MAC address
      based accounting will be provided.</p>

      <p>CARP is an alternative to VRRP. In contrast to VRRP it has full
      support for IPv6 and uses crypto to protect the advertisements. It
      was developed by OpenBSD due to concerns that the HSRP patent might
      cover VRRP and CISCO might defend its patent. CARP has, since then,
      improved a lot over VRRP.</p>

      <p>CARP is implemented as an in-kernel multicast protocol and
      displays itself as a pseudo interface to the user. This makes
      configuration and administration very simple. CARP also
      incorporates MAC based load-balancing.</p>

      <p>Patches for RELENG_5 and recent HEAD are available from the URL
      above. I plan to import these patches in the course of the next two
      to four month. RELENG_5 has all necessary ABI to support CARP and I
      might MFC it for release 5.4 or 5.5 - depending how well the HEAD

      <p>In my continuing quest to secure the mechanisms by which FreeBSD
      users keep their systems up to date, I've added a new tool:
      Portsnap. Available as sysutils/portsnap in the ports tree, this
      utility securely downloads and updates a compressed snapshot of the
      ports tree; this can then be used to extract or update an
      uncompressed ports tree. In addition to operating in an end-to-end
      secure manner thanks to RSA signatures, portsnap operates entirely
      over HTTP and can use under one tenth of the bandwidth of cvsup for
      users who update their ports tree more than once a week.</p>

      <p>FreeBSD Update -- my utility for secure and efficient binary
      tracking of the Security/Errata branches -- continues to be widely
      used, with over 100 machines downloading security or errata updates
      daily.</p>

      <p>At some point in the future I intend to bring both of these
      utilities into the FreeBSD base system, probably starting with
      portsnap.</p>

      even easier, a FreeBSD-based operating system that works directly
      from a CD, without touching your hard drive.</p>

      <p>On December, 6th, 2004, FreeSBIE Staff released FreeSBIE 1.1,
      based on FreeBSD 5.3-RELEASE. Some of the innovations are: a
      renewed series of scripts to support power users in the use of
      FreeSBIE 1.1, an installer to let users install FreeSBIE 1.1 on
      their hard drives, thus having a powerful operating system such as
      FreeBSD, but with all the personalizations FreeSBIE 1.1 carries,
      the presence of the best open source software, chosen and
      personalized, such as X.Org 6.7, XFCE 4.2RC1, Firefox 1.0 and
      Thunderbird 0.9.2.</p>

      <p>We haven't produced a status report in a while, but that's just
      because we've been busy. Since our last report in March 2004, we
      have added three new team members: Koop Mast (kwm), Jeremy
      Messenger (mezz), and Michael Johnson (ahze). Jeremy has been quite
      helpful in GNOME development porting while Michael and Koop have
      been focusing on improving GNOME multimedia, especially GStreamer.
      The stable release of GNOME is now up to 2.8.2, and we are actively
      working on the GNOME 2.9 development branch with is slated to
      become 2.10 on March 9 of this year.</p>

      <p>The
      <a href="http://www.FreeBSD.org/gnome/docs/faq2.html#q21">GNOME
      Tinderbox</a>

      is still cranking away, and producing packages for both the stable
      and development releases of GNOME for all supported i386 versions
      of FreeBSD.</p>

      <p>Thanks to Michael Johnson, the FreeBSD GNOME team has recently
      been given
      <a
      href="http://people.FreeBSD.org/~ahze/firefox_thunderbird-approved.txt">
      permission to use the Firefox and Thunderbird names</a>

      , official icons, and to produce officially branded builds. Mozilla
      has also been very interested in merging our local patches back
      into the official source tree. This should greatly improve the
      quality of Firefox and Thunderbird on FreeBSD moving forward.</p>

      <p>Finally, Adam Weinberger (adamw) has been pestering the team
      for photos so that we can finally show the community who we are. It
      is still unclear as to whether or not this will attract more
      FreeBSD GNOME users, or land us on the Homeland Security no-fly
      list.</p>

      <p>Lots of changes happened inside the network stack that will
      hopefully be covered by a separate report. Outside of the network
      stack, several changes were made however including changes to proc
      locking, making the kernel thread scheduler preemptive, fixing
      several priority inversion bugs in the scheduler, and a few
      performance tweaks in the mutex implementation.</p>

      <p>Locking work on struct proc and its various substructures
      continued with locking added where needed for struct uprof, struct
      rusage, and struct pstats. This also included reworking how the
      kernel stores process time statistics to store the raw struct
      bintime and tick counts internally and only compute the more user
      friendly values when requested via getrusage() or wait4().</p>

      <p>Support for kernel thread preemption was added to the scheduler.
      Basically, when a thread makes another thread runnable, it may
      yield the current CPU to the new thread if the new thread has a
      more important priority. Previously, only interrupt threads
      preempted other threads and the implementation would occasionally
      trigger spurious context switches. This change exposed bugs in
      other parts of the kernel and was turned off by default in
      RELENG_5. Currently, only the i386, amd64, and alpha platforms
      support native preemption.</p>

      <p>Several priority inversion bugs present in the scheduler due to
      various changes to the kernel from SMPng were also fixed. Most of
      the credit for these fixes belongs Stephan Uphoff who has recently
      been added as a new committer. Fixes include: closing a race in the
      turnstile wakeup code, changing the sleep queue code to store
      threads in FIFO order so that the sleep queue wakeup code properly
      handles having a thread's priority changes, and abstracting the
      concept of priority lending so that the thread scheduler is now
      able to properly track priority inheritance and handle priority
      changes for threads blocked on a turnstile.</p>

      <p>Works in progress include separating critical sections from spin
      mutexes some so that bare critical sections become very cheap as
      well as continuing to change the various ABI compatibility layers
      to use in-kernel versions of system calls to reduce stackgap usage
      and make the system call wrappers MPSAFE.</p>

      <p>The ACPI PCI link support code was reworked to work around some
      limitations in the previous implementation. The new version more
      closely matches the current non-ACPI $PIR link support.
      Enhancements include disabling unused link devices during boot and
      using a simpler and more reliable algorithm for choosing ISA IRQs
      for unrouted link devices.</p>

      <p>Support for using the local APIC timer to drive the kernel
      clocks instead of the ISA timer and i8254 clock is currently being
      worked on in the jhb_clock perforce branch. It is mostly complete
      and will probably hit the tree in the near future. By letting each
      CPU use its own private timer to drive the kernel clocks, the
      kernel no longer has to IPI all the other CPUs in the system every
      time a clock interrupt occurs.</p>

        <li>OpenOffice.org 2.0 is planned to be released in March 2005.
        Currently developer snapshot versions are available. Now one of
        the developer version has been ported, and committed to ports
        tree (/usr/ports/editors/openoffice-2.0-devel).</li>

        <li>Packages for 5.3-RELEASE are available at

        with the language pack.</li>

        <li>Almost all of the patches required to build will be
        integrated to master.
        <a href="http://www.openoffice.org/issues/show_bug.cgi?id=40187">
        http://www.openoffice.org/issues/show_bug.cgi?id=40187</a>
        </li>

        <li>Now we have three external ports : lang/gcc-ooo,
        devel/bison-devel and devel/epm. To avoid regressions and bugs of
        gcc, we use the exactly same gcc as Hamburg team (former
        StarDivision) uses. We need bison later than 1.785a. Note this
        port CONFLICTS with devel/bison. Epm is a package manager which
        now OpenOffice.org uses.</li>
      </ul>

      OpenOffice.org 1.1 status
      <ul>
        <li>1.1.4 has been ported and committed to ports tree.</li>

        <li>Packages are available at

        .</li>

        <li>Now recognizes Linux version of Java JDKs.</li>
      </ul>

      General
      <ul>
        <li>Invoking OpenOffice.org from command line has been changed.
        Now `.org' is mandatory. e.g. openoffice-1.1.4 -&gt;
        openoffice.org-1.1.4. Since the name of the software is
        OpenOffice.org, not OpenOffice. We are also considering the name
        of the ports (/usr/ports/editors/openoffice-2.0-devel -&gt;
        openoffice.org2-devel etc)</li>

        <li>Now marked as BROKEN OOo ports for prior than 5.3-RELEASE and
        4.11-RELEASE. These ports have been suffering from a minor
        implementation difference of rtld.c between FreeBSD and Linux,
        Solaris, NetBSD. We have been applying a patch adding _end in
        mapfile. We need this since rtld depend on existence of _end
        symbol in obj_from_addr_end, unfortunately this seem to induce
        hard-to-solve errors. A great progress has been made kan, rtld
        now do not depend on _end. A fix was committed 2004/02/25

      <p>FreeBSD 5.3 is the first release to include PF. It went out
      okay, but some bugs were discovered too late to make it on the CD.
      It is recommend to update `src/sys/contrib/pf' to RELENG_5. The
      specific issues addressed are:</p>

      <ul>
        <li>Possible NULL-deref with user/group rules.</li>

        <li>Crash with binat on dynamic interfaces.</li>

        <li>Silent dropping of IPv6 packets with option headers.</li>

        <li>Endless loops with `static-port' rules.</li>
      </ul>

      <p>Most of these issues were discovered by FreeBSD users and got
      fed back to OpenBSD. This is a prime example of open source at

    <body>
      <p>Following a number of mailing lists discussions on the topic,
      work has been progressing on the development of a new modular input
      device layer for FreeBSD. The purpose of this is twofold:</p>

      <ul>
        <li>Easier development of new input device drivers.</li>

        <li>Support for concurrent use of multiple input devices,
        particularly the hot-pluggable kind.</li>
      </ul>

      <p>Currently, implementing support for new input devices is a
      painful process and there is great potential for code-duplication.
      The new input device layer will provide a simple API for developers
      to send events from their hardware on to the higher regions of the
      kernel in a consistent way, much like the 'input-core' driver in
      the Linux kernel.</p>

      <p>Using multiple input devices at the moment is painful at best.
      With the new input device layer, events from different devices will
      be properly serialized before they are sent to other parts of the
      kernel. This will allow one to easily use, for instance, multiple
      USB keyboards in a virtual terminal.</p>

      <p>The work on this is still in very rudimentary state. It is
      expected that the first visible changes will be committed to
      -CURRENT around late February or early March.</p>

      <p>Since the last report on the Ports Collection, much has changed.
      Organizationally, the portmgr team saw the departure of some of the
      long-term members, and the addition of some newer members, Oliver
      Eikemeier, Kirill Ponomarew and Mark Linimon. Later on, portmgr
      also had to say goodbye to Will Andrews. In addition, we have
      gained quite a few new ports committers during this time period,
      and their contributions are quite welcome!</p>

      <p>Most effort was devoted to two releases. The 5.3 release saw an
      especially long freeze period, but due to the good shape of the
      ports tree, the freeze for the 4.11 could be kept to a minimum.
      Several iterations of new infrastructure changes were tested on the
      cluster and committed. Also, the cluster now builds packages for
      6-CURRENT, increasing the total number of different build
      environment to 10.</p>

      <p>Additionally, several sweeps through the ports tree were made to
      bring more uniformity in variables used in the different ports and
      their values, e.g.
      <tt>BROKEN</tt>

      ,
      <tt>IGNORE</tt>

      ,
      <tt>DEPRECATED</tt>

      ,
      <tt>USE_GCC</tt>

      , and others.</p>

      <p>In technical terms, the largest change was moving to the X.org
      codebase as our default X11 implementation. At the same time, code
      was committed to be able to select either the X.org code or the
      XFree86 code, which also saw an update during that time. Due to
      some hard work by Eric Anholt, new committer Dejan Lesjak, and Joe
      Marcus Clarke, all of this happened more smoothly than could have
      reasonably been expected.</p>

      <p>As well, GNOME and KDE saw updates during this time, as did Perl
      and the Java framework. Further, there were some updates to the
      Porter's Handbook, but more sections are still in need of updates
      to include recent changes in practices. Also, during this time,
      Bill Fenner was able to fix a bug in his
      <a href="http://people.FreeBSD.org/~fenner/portsurvey">distfile
      survey</a>

      .</p>

      <p>Shortly before the release for 4.11 our existing linux_base was
      marked forbidden due to security issues. A lot of effort was spent
      to upgrade the default version to 8 from 7 to ship 4.11 with a
      working linuxolator.</p>

      <p>Due to stability problems in the April-May timeframe, the
      package builds for the Alpha were dropped. After Ken Smith and
      others put some work into the Alphas in the build cluster, package
      builds for 4.X were reenabled late in 2004.</p>

      <p>Ports QA reminders -- portmgr team members are now sending out
      periodic email about problems in the Ports Collection. The current
      set includes:
      <ul>
        <li>a public list of all ports to be removed due to security
        problems, build failures, or general obsolescence, unless they
        are fixed first</li>

        <li>private email to all maintainers of the affected ports
        (including ports dependent on the above)</li>

        <li>private email to all maintainers of ports that are marked
        <tt>BROKEN</tt>

        and/or
        <tt>FORBIDDEN</tt>
        </li>

        <li>private email to maintainers who aren't committers, who have
        PRs filed against their ports (to flag PRs that might never have
        been Cc:ed to them)</li>

        <li>public email about port commits that break building of
        <tt>INDEX</tt>
        </li>

        <li>public email about port commits that send the revision
        metadata backwards (and thus confuse tools like portupgrade)</li>
      </ul>

      The idea behind each of these reminders is to try to increase the
      visibility of problems in the Ports Collection so that problems can
      be fixed faster.</p>

      <p>Finally, it should be noted that we passed yet another milestone
      and the Ports Collection now contains over 12,000 ports.</p>

      <task>The majority of our build errors are still due to compilation
      problems, primarily from the gcc upgrades. Thanks to the efforts of
      many volunteers, these are decreasing, but there is still much more
      work to be done.</task>

      <task>The next highest number of build errors are caused by code
      that does not build on our 64-bit architectures due to the
      assumption that "all the world's a PC."
      <a

      <task>A lot of progress has been meed to crack down on ports that
      install files outside the approved directories and/or do not

    <body>
      <p>During 2004, there were several notable changes and events
      related to the FreeBSD Security Officer role and Security Team.</p>

      <p>The charter for the Security Officer (SO) as approved by Core in
      2002 was finally published on the web site. This document describes
      the mission, responsibilities, and authorities of the SO. (The
      current SO is Jacques Vidrine.)</p>

      <p>The SO is supported by a Deputy SO and the Security Team. In
      April, Chris Faulhaber resigned as Deputy SO and Dag-Erling
      Smorgrav was appointed in his place. Also during the year, the
      following team members resigned: Julian Elischer, Bill Fumerola,
      Daniel Harris, Trevor Johnson, Kris Kennaway, Mark Murray, Wes
      Peters, Bruce Simpson, and Bill Swingle; while the following became
      new members: Josef El-Rayes, Simon L. Nielsen, Colin Percival, and
      Tom Rhodes. A huge thanks is due to all past and current members!
      The current Security Team membership is published on the web
      site.</p>

      <p>With the release of FreeBSD 4.8, the SO began extended support
      for some FreeBSD releases and their corresponding security
      branches. "Early adopter" branches, such as FreeBSD 5.0
      (RELENG_5_0), are supported for at least six months. "Normal"
      branches are supported for at least one year. "Extended" branches,
      such as FreeBSD 5.3 (RELENG_5_3), are supported for at least two
      years. The currently supported branches and their estimated "end of
      life" (EoL) dates are published on the FreeBSD Security Information
      web page. In 2004, four releases "expired": 4.7, 4.9, 5.1, and
      5.2.</p>

      <p>With the releases of FreeBSD 4.10 and 5.3, the SO and the
      Release Engineering team extended the scope of security branches to
      incorporate critical bug fixes unrelated to security issues.
      Currently, separate Errata Notices are published for such fixes. In
      the future, Security Advisories and Errata Notices will be merged
      and handled uniformly.</p>

      <p>17 Security Advisories were published in 2004, covering 8 issues
      specific to FreeBSD and 9 general issues.</p>

      <p>2004 also saw the introduction of the Vulnerabilities and
      Exposures Markup Language (VuXML). VuXML is a markup language
      designed for the documentation of security issues within a single
      package collection. Over 325 security issues in the Ports
      Collection have been documented already in the FreeBSD Project's
      VuXML document by the Security Team and other committers. This
      document is currently maintained in the ports repository, path
      ports/security/vuxml/vuln.xml. The contents of the document are
      made available in a human-readable form at the FreeBSD VuXML web
      site. The "portaudit" tool can be used to audit your local system
      against the listed issues. Starting in November, the popular
      FreshPorts.org web site also tracks issues documented in VuXML.</p>

      <p>Support of FrameRelay AnnexD was added as a historical commit.
      Many of Cronyx users were expecting this commit for a long long

      <p>Support for multibyte characters has been added to many more
      base system utilities, including basename, col, colcrt, colrm,
      column, fmt, look, nl, od, rev, sed, tr, and ul. As a result of
      changes to the C library (see below), most utilities that perform
      regular expression matching or pathname globbing now support
      multibyte characters in these aspects.</p>

      <p>The regular expression matching and pathname globbing routines
      in the C library have been improved and now recognize multibyte
      characters. Various performance improvements have been made to the
      wide character I/O functions. The obsolete 4.4BSD "rune" interface
      and UTF2 encoding have been removed from the 6-CURRENT branch.</p>

      <p>Work is progressing on implementations of the POSIX iconv and
      localedef interfaces for potential inclusion into the FreeBSD 6.0

      <p>The ATA driver is undergoing quite a few important changes,
      mainly it is being converted into modules so it can be
      loaded/unloaded at will, and just the pieces for wanted
      functionality need be present.</p>

      <p>This calls for ata-raid to finally be rewritten. This is almost
      done for reading metadata so arrays defined in the BIOS can be
      used, and its grown quite a few new metadata formats. This also
      paves the way for ataraid to finally be able to take advantage of
      some of the newer controllers "RAID" abilities. However this needs
      more work to materialize but now its finally possible</p>

      <p>There is also support coming for a few new chipsets as
      usual.</p>

      <p>The work is just about finished enough that it can be released
      as patches to sort out eventual problems before hitting current.
      The changes are pretty massive as this touches all over the driver
      infrastructure, so lots of old bugs and has also been spotted and
      fixed during this journey</p>

      polling done by the old code). The main change from the previous
      client is that there is one dhclient process per interface as
      opposed to one for the entire system. This necessitates changes to
      the system startup scripts.</p>

      <p>Incorporation into the base system is waiting on a volunteer who

      <p>The ifconfig program used to configure network interfaces was
      overhauled. Over the years ifconfig has grown into a complex and
      often contorted piece of software that is hard to understand and
      difficult to maintain. The primary motivation for this work was to
      enable minimal configurations (for embedded use) without changing
      the code and to support future additions in a modular way.
      Functionality is now broken out into separate files and operations
      are registered with the central ifconfig code base. Features are
      configured simply by specifying which code is to be included when
      building the program.</p>

      <p>In the future the plan is for ifconfig to auto-load
      functionality through dynamic libraries. This mechanism will allow,
      for example, third party software packages to provide kernel
      services and ifconfig add-on code without changing the base
      system.</p>

      <p>The netperf project is working to enhance the performance of the
      FreeBSD network stack. This work grew out of the SMPng Project,
      which moved the FreeBSD kernel from a "Giant Lock" to more
      fine-grained locking and multi-threading. SMPng offered both
      performance improvement and degradation for the network stack,
      improving parallelism and preemption, but substantially increasing
      per-packet processing costs. The netperf project is primarily
      focused on further improving parallelism in network processing
      while reducing the SMP synchronization overhead. This in turn will
      lead to higher processing throughput and lower processing latency.
      Tasks include completing the locking work, optimizing locking
      strategies, amortizing locking costs, introducing new
      synchronization primitives, adopting non-locking synchronization
      strategies, and improving opportunities for parallelism through
      additional threading.</p>

      <p>Between July, 2004, and December, 2004, the Netperf project did
      a great deal of work, for which there is room only to include
      limited information. Much more information is available by visiting
      the URLS above, including information on a variety of on-going
      activities. Accomplishments include:</p>

      <p>FreeBSD profile.sh is targeted at laptops. It allows to define
      multiple network environments (eg, home, work), and will then
      detect in which environment the laptop is started and configure it
      accordingly. Almost everything from under /etc can be configured
      per environment, and only the overrides to the default /etc have to
      be defined. Suspending in one environment and resuming in a
      different one is also supported.</p>

      <p>Proper integration into the acpi/apm and several small
      improvements are underway. More testing with different system
      configurations is needed.</p>

      <p>At long last, FreeBSD 5.3 was released in November of 2004. This
      marked the start of the RELENG_5/5-STABLE branch and the beginning
      of the 6-CURRENT development branch. Many thanks to the tireless
      efforts of the FreeBSD developer and user community for making this
      release a success.</p>

      <p>FreeBSD 4.11 release engineering is also now in progress. This
      will be the final release from the 4.x series and is mainly
      incremental bug fixes and a handful of feature additions. Of note
      is that the IBM ServeRAID 'IPS' driver is now supported on 4.x and
      will be included in this release, and the Linux emulation layer has
      been updated to support a RedHat 8.0 userland. The release is
      expected to be available on January 24.</p>

      <p>Looking forward, there will be several FreeBSD 5.x releases in
      the coming year. FreeBSD 5.4 release engineering will start in
      March, and FreeBSD 5.5 release engineering will likely start in
      June. These releases are expected to be more conservative than
      previous 5.x releases and will follow the same philosophy as
      previous -STABLE branches of fixing bugs and adding incremental
      improvements while maintaining API stability.</p>

      <p>For the 6-CURRENT development branch as well as all future
      development and stable branches, we are planning to move to a
      schedule with fixed timelines that move away from the uncertainty
      and wild schedule fluctuations of the previous 5.x releases. This
      means that major branches will happen at 18 month intervals, and
      releases from those branches will happen at 4 month intervals.
      There will also be a dedicated period of testing and bug fixing at
      the beginning of each branch before the first release is cut from
      that branch. With the shorter and more defined release schedules,
      we hope to lessen the problem of needed features not reaching users
      in a reasonable time, as happened too often with 5.x. This is a
      significant change in our strategy, and we look forward to
      realizing the benefits of it. This will kick off with the RELENG_6
      branch happing in June of 2005, followed by the 6.0 release in
      August of 2005.</p>

      <p>Also on the roadmap is a plan to combine the live-iso disk2 and
      the install distributions of disk1 into a single disk which can be
      used for both installation and for recovery. 3rd party packages
      that currently reside on disc1 will be moved to a disk2 that will
      be dedicated to these packages. This move will allow us to deal
      with the ever growing size of packages and also provide more
      flexibility to vendors that wish to add their own packages to the
      releases. It also opens the door to more advanced installers being
      put in place of sysinstall. Anyone interested in helping with this
      is encouraged to contact us.</p>

    <title>Wireless Networking Support</title>

      <p>The wireless networking layer was updated to support the 802.1x,
      WPA, and 802.11i security protocols, and the WME/WMM multi-media
      protocol. As part of this work extensible frameworks were added for
      cryptographic methods, authentication, and access control.
      Extensions are implemented as loadable kernel modules that hook
      into the net80211 layer. This mechanism is used, for example, to
      implement WEP, TKIP, and CCMP crypto protocols. The Atheros driver
      (ath) is currently the only driver that uses the full set of
      features. Adding support to other drivers is simple but waiting on
      volunteers. Ports of the wpa_supplicant and hostapd programs enable
      use of the new security protocols.</p>

      <p>The support for tracking stations in a bss (managed or adhoc)
      and stations found when scanning was overhauled. Multiple tables
      are now used, each with different management policies, reference
      counting is now done consistently, and inactivity processing is
      done more intelligently (e.g. associated stations are probed before
      removal). This is the first step towards proper roaming support and
      other advanced features.</p>

      <p>AP power save support was added. Associated stations may now
      operate in power save mode; frames sent to them will be buffered
      while they are sleeping and multicast traffic will be deferred
      until after the next beacon (per the 802.11 protocol). Power save
      support is required in a standards-compliant access point. Only the
      ath driver currently implements power save support.</p>

      <p>Work is actively going on to add Atheros' SuperG capabilities,
      WDS, and for multi-bss support (ssid and/or bssid) on a single
      device.</p>
