  <section>
    <title>Introduction</title>

    <p>One of the benefits of the FreeBSD development model is a focus
    on centralized design and implementation, in which the operating
    system is maintained in a central repository, and discussed on
    centrally maintained lists. This allows for a high level of
    coordination between authors of various components of the system,
    and allows policies to be enforced over the entire system, covering
    issues ranging from architecture to style. However, as the FreeBSD
    developer community has grown, and the rate of both mailing list
    traffic and tree modifications has increased, making it difficult
    even for the most dedicated developer to remain on top of all the
    work going on in the tree.</p>

    <p>The FreeBSD Monthly Development Status Report attempts to
    address this problem by providing a vehicle that allows developers
    to make the broader community aware of their on-going work on
    FreeBSD, both in and out of the central source repository. This is
    the first issue, and as such is an experiment. For each project and
    sub-project, a one paragraph summary is included, indicating
    progress since the last summary (in this case, simply recent
    progress, as there have been no prior summaries).</p>

    <p>This status report may be reproduced in whole or in part, as
    long as the source is clearly identified and appropriate credit
    given.</p>
  </section>

  <section>
    <title>Future Editions</title>

    <p>Assuming there is some positive feedback on this idea, and that
    future submissions get made such that there is content for future
    issues, the goal is to release a development status report once a
    month. As such, the next deadline will be July 31, 2001, with a
    scheduled publication date in the first week of August. This will
    put the status report on a schedule in line with the calendar, as
    well as providing a little over a month until the next deadline,
    which will include a number of pertinent events, including the
    Annual USENIX Technical Conference in Boston, MA. Submissions
    should be e-mailed to:</p>

    <blockquote>
      <a href="mailto:robert+freebsd.monthly@cyrus.watson.org">
      robert+freebsd.monthly@cyrus.watson.org</a>
    </blockquote>

    <p>Many submitters will want to wait until the last week of July so
    as to provide the most up-to-date status report; however,
    submissions will be accepted at any time prior to that date.</p>

      <p>The FreeBSD Binary Updater Project aims to provide a secure
      mechanism for the distribution of binary updates for FreeBSD.
      This project is complementary to the Open Packages and libh
      efforts and there should be very little overlap with those
      projects. The system uses a client / server mechanism that allows
      clients to install any known "profile" or release of FreeBSD over
      the network. Where a specific profile might contain a specific
      set of FreeBSD software to install, additional packages, and
      configuration actions that make it more ideal for a specific
      environment (ie FreeBSD 4.3 Secure Web Server Profile)</p>

      <p>The system can currently be used to install a FreeBSD system
      or perform the most simple of upgrades but many features are
      absent. In particular, the client is in its infancy and much work
      remains to be done. We need additional developers so please get
      in touch with us at 
      <a href="mailto:updater@osd.bsdi.com">updater@osd.bsdi.com</a>

      if you are interested in spending some cycles on this.</p>

      <p>Poul-Henning Kamp kicked off a drive to get our GNATS PR
      database cleaned up so the wheat can be sorted from the chaff.
      Progress is good, but there is still a lot of work to do. Give a
      hand if you can. Remember: every unhandled PR is a pissed off
      contributor or user.</p>

    <body>
      <p>I'm in the process of rewriting the CVSROOT/scripts to make
      them more clean and configurable. A lot of other projects also
      use these and so it makes sense to make them as easy to use in
      other environments as possible.</p>

      <p>Status: work in progress. There is now a configuration file,
      but not all the scripts use it yet.</p>

      <p>Work is progressing on implementing true cloning devices in
      DEVFS. Brian Somers and Poul-Henning Kamp are working to make
      if_tun the first truly cloning driver in the system. Next will be
      the pty driver and the bpf driver.</p>

      <p>From July 1st DEVFS will be standard in -current.</p>

      <p>Added the digi driver. Initial work was done by John Prince
      &lt;johnp@knight-trosoft.com&gt;, but all the modular stuff was
      done by me and initial work on supporting Xe and Xi cards (ala
      dgb) was done by me. I'm now awaiting an Xe card being sent from
      joerg@ (almost a donation) so that I can get that side of things
      working properly.</p>

    <body>
      <p>Ben Smithurst has written a "diskcheckd" daemon which will
      read all sectors on the disks over a configured period. With
      recent increases in disksizes it is by no means a given that disk
      read errors will be discovered before they are fatal. This daemon
      will hopefully result in the drive firmware being able to
      relocate bad sectors before they become unreadable. This code is
      now committed to 5.0-CURRENT.</p>

      <p>In the last month (May-June), the new fxp driver was brought
      into -stable. This new driver uses the common MII code, so
      support for new PHYs is easy to add. Support for the new Intel
      82562 chips was added. The driver was updated to add VLAN support
      and a workaround for a bug affecting Intel 815-based boards.</p>

      <p>The FreeBSD Java Project has continued its "behind the scenes"
      work over the last month. Progress was made both technically,
      with the help of Bill Huey (of Wind River), on a port of JDK
      1.3.1 and legally, with Nate Williams continuing negotiations
      with Sun on a mutually acceptable license to release a binary
      Java 2 SDK under. The JDK 1.2.2 port has also seen some
      development, with a new patchset likely to be released soon which
      includes JPDA and NetBSD support (the latter courtesy of Scott
      Bartram).</p>

      <p>The Kernel Graphics Interface project has worked for several
      years to provide a framework for graphic drivers under Linux
      receiving input from other groups like the UDI project. Currently
      the KGI core implementation is quite settled, as is the driver
      coding model as a whole. Work is being done to newbussify KGI and
      produce a kld, as part of a future redesign of the graphics
      subsystem in FreeBSD. KGI will be an alternative for graphic card
      producers that don't accept the XFree86 model of userland graphic
      adapters and will also provide accelerated support for any other
      graphic alternative.</p>

      <p>Pseudofs is a framework for pseudo-filesystems, like procfs
      and linprocfs. The goal of pseudofs is twofold:</p>

      <ul>
        <li>eliminate code duplication between (and within) procfs and
        linprocfs</li>

        <li>isolate procfs and linprocfs from the complexities of the
        vfs system to simplify maintenance and further
        development.</li>
      </ul>

      <p>Pseudofs has reached the point where it is sufficiently
      functional and stable that linprocfs has been almost fully
      reimplemented on top of it; the only bit that's missing is the
      proc/&lt;pid&gt;/mem file.</p>

      <p>The primary to-do item for pseudofs right now is to add
      support for writeable files (which are required for procfs, and
      are quite a bit less trivial to handle than read-only files). In
      addition, pseudofs needs either generic support for raw
      (non-sbuf'ed, possibly mmap'able) files, or failing that,
      special-case code to handle proc/&lt;pid&gt;/mem.</p>

      <p>The SMPng project aims to provide multithreaded support for
      the FreeBSD kernel. Currently the kernel still runs almost
      exclusively under the Giant kernel lock. Recently, progress has
      been made in locking the process group and session structures as
      well as file descriptors by Seigo Tanimura-san. Alfred Perlstein
      has also added in a giant lock around the entire virtual memory
      (VM) subsystem which will eventually be split up into several
      smaller locks. The locking of the VM subsystem has proved tricky,
      and some of the current effort is focused on finding and fixing a
      few remaining bugs in on the alpha architecture.</p>

      Burkholder will be porting the kernel, and Ade Lovett has
      expressed an interest in working on userland. Recent work on the
      project includes:</p>

      <ul>
        <li>built a gnu cross toolchain targeting sparc64</li>

        <li>obtained remote access to an ultra 5 development machine
        (thanks to emmy)</li>

        <li>developed a minimal set of headers and source files to
        allow the kernel to be compiled and linked</li>

        <li>implemented a mini-loader which relocates the kernel, maps
        it into the tlbs and calls it</li>

        <li>nabbed Benno Rice's openfirmware console driver which
        allows printf and panic to work</li>
      </ul>

      <p>At this point the kernel can be net-booted and prints the
      FreeBSD copyright before calling code that is not yet
      implemented. I am currently working on a design for the pmap
      module and plan to begin implementation in the next few days.</p>

      <p>The TrustedBSD Project seeks to improve the security of the
      FreeBSD operating system by adding new security features, many
      derived from common trusted operating system requirements. This
      includes Access Control Lists (ACLs), Fine-grained Event Logging
      (Audit), Fine-grained Privileges (Capabilities), Mandatory Access
      Control (MAC), and other architecture features, including file
      system extended attributes, and improved object labeling.</p>

      <p>Individual feature status reports are documented separately
      below; in general, basic features (such as EAs, ACLs, and kernel
      support for Capabilities) will be initially available in
      5.0-RELEASE, conditional on specific kernel options. A
      performance-enhanced version of EAs is currently being targeted
      at 6.0-RELEASE, along with an integrated capability-aware
      userland, and MAC support.</p>

      <p>The kernel part of the capability implementation is mostly
      finished; all uses of suser() and suser_xxx() and nearly all
      comparisons of uid's with 0 have been converted to use the newly
      introduced cap_check() call. Some details still need
      clarification. More documentation for this needs to be done.</p>

      <p>POSIX.2c-compatible getfcap and setfcap programs have been
      written. Experimental capability support in su(1), login(1),
      install(1) and bsd.prog.mk is being tested.</p>

      <p>Support for capabilities, ACL's, capabilities and MAC labels
      in tar(1) is being developed; only the capability part is tested
      right now. Generic support for extended attributes is planned,
      this will require extensions to the current EA interface, which
      are written and will probably be committed to -CURRENT in a few
      weeks. A port of these features to pax(1) is planned.</p>

      <p>An initial prototype of a Mandatory Access Control
      implementation was completed earlier this year, supporting
      Multi-Level Security, Biba Integrity protection, and a more
      general jail-based access control model. Based on that
      implementation, I'm now in the process of improving the FreeBSD
      security abstractions to simplify both the implementation and
      integration of MAC support, as well as increase the number of
      kernel objects protected by both discretionary and mandatory
      protection schemes. Generic object labeling introduces a
      structure not dissimilar in properties to the kernel ucred
      structure, only it is intended to be associated with kernel
      objects, rather than kernel subjects, permitting the creation of
      generic security protection routines for objects. This would
      allow the easy extension of procfs and devfs to support ACLs and
      MAC, for example. A prototype is underway, with compiling and
      running code and simple protections now associated with
      sysctl's.</p>
