- <title>Introduction</title>
-
- <p>In the month of September, the FreeBSD Project continued its
- investment in long-term projects, including continuing work on a
- fine-grained SMP implementation, support for Kernel Schedulable
- Entities (KSE) supporting highly efficient threading, and
- broadening support for modern hardware platforms, including Intel's
- new IA64 architecture, UltraSparc, and PowerPC. Additional focus
- was placed on the release process, including work on the release
- notes infrastructure, support for DVD releases, and work on a
- binary updating tool.</p>
-
- <p>Due to the delay in getting the September report out the door,
- the November status report will also cover October. During the
- month of November, we look forward to BSDCon Europe, the first such
- event outside the continental United States. The USENIX conference
- paper submission deadlines are also in November, and FreeBSD users
- and developers are encouraged to submit to the general and FREENIX
- tracks. Please see www.usenix.org for more information.</p>

- <p>PRFW provides hooks in the FreeBSD kernel, allowing users to
- insert their own checks in system calls and various kernel
- functions. PRFW is nearing 0.5, which will incorporate numerous
- structural changes such as, much faster per-process hooks, kernel
- function hooks, plus, a new way of adding hooks which would
- enable users to reference hooks by a string.</p>

- created some first packages from existing ports and installed
- those libh packages on my system only using libh's tools,
- including registering all the files in the package database,
- recording their checksums etc. Patches to the disk editor have
- been submitted, which include functionality to write the changes
- in the fdisk part and initial support for a disk label editor.
- We'll soon have a new committer.</p>

- <p>FreeBSD 4.4-RELEASE was the first release of FreeBSD with its
- new-style release documentation. Both English and Japanese
- versions of these documents were created. Regularly-built
- snapshots of -CURRENT and 4-STABLE release documentation are now
- available on the Web site, but they require a little HTML
- infrastructure to make them viewer-friendly. I intend to continue
- updating my snapshot site at the URL above, at least for a little
- while.</p>
-
- <p>Call for help: The hardware compatibility lists need to be
- updated in the areas of the Alpha architecture, USB devices, and
- PCCARD devices. I'm looking for volunteers to help; interested
- parties should contact me at the email address above. DocBook
- experience is not required; familiarity with the hardware above
- would be very helpful.</p>

- <p>As you know, in march 2001 the version 2.3 of TIRPC has been
- committed together with many userland changes. Alfred Perlstein
- and Ian Dowse have helped me a lot with the porting effort and if
- I had problems with understanding the code.</p>
-
- <p>Most bugs are now fixed, some remaining areas to fix are
- secure RPC (keyserv) and unix domain support. I've patches for
- these area available. Ian Dowse fixed a lot of outstanding bugs
- in the rpcbind binary itself. Thank you Ian !</p>
-
- <p>The plan is now to migrate slowly towards TIRPC 2.8, which is
- threadsafe for the server- and clientside. One first patch I've
- made available on my URL. TIRPC 2.8 is licensed under the "Sun
- Standards License Version 1.0" and we have to add some license
- lines and the license itself to all modified files.</p>
-
- <p>A example is timed_clnt_create.diff which can be found on the

- <p>I am pleased to announce that as of 1 AM Friday October 19th,
- the sparc64 port boots to single user mode. A few binaries from
- the base system have been built and verified to work properly.
- Much of this work is still in review for commit, but will be
- integrated into the cvs tree as soon as possible. EBus support
- has been ported from NetBSD, and ISA support has been written.
- The PCI host bridge code has stabilized, and busdma seems to work
- correctly now. The sio driver has had EBus support added, and the
- ATA driver has been modified so that it works on big-endian
- systems and uses the busdma API. With these changes, a root file
- system can now be successfully mounted from ATA disks on sparc64,
- even in DMA mode. The gem driver, which supports Sun GEM and ERI
- and Apple GMAC and GMAC2 ethernet adaptor, has been ported from
- NetBSD but has not yet had sufficient testing.</p>

- <p>Currently, a single device may act as a console at any time,
- which requires the user to choose the console device at boot
- time. With the upcoming network console support, it is desirable
- to allow multiple console devices which behave identically, and
- to alter consoles while the kernel is running.</p>
-
- <p>The code is completed, and needs some final polishing to clean
- up the rough edges. Console output can be sent to both syscons
- and sio, (as well as the network) and when in ddb, input can be
- taken from any input source. A small control program allows
- adding and removing consoles on the fly.</p>

- <p>This project's goal is to add low level network functionality

- available for remote debugging with ddb or gdb. A secondary
- target is to utilize the code to perform network crash dumps. The
- design assumes that the network card and driver are working, but
- does not rely on other parts of the kernel.</p>
-
- <p>Initial development has been fairly rapid, and a minimal
- TCP/IP stack has been written. It is currently possible to telnet
- to a machine which is at the ddb&gt; prompt and interact with the
- debugger.</p>

- <p>In the last month, not a lot has happened other than settling
- in of the big August commit. Largely due to me having a sudden
- increased workload at work, and a need for increased time to be
- spent elsewhere. However some design work has proceeded. The API
- has firmed up somewhat and several people have been reading
- through what has been done already in order to be able to help in
- the next phase.</p>
-
- <p>Milestone 3 will be to have the ability to generate and remove
- multiple threads/KSEs per process. Milestone 3 will NOT require
- that doing so will be safe. (especially in SMP systems), i.e.
- locking issues will not be fully addressed, so while some testing
- will be possible, it will not be possible to actually run in this
- mode with any load.</p>
-
- <p>This will require allocators and destructors for the new
- structures. Creation of the syscalls. Generation of an accurate
- written API for the userland crew. Writing of the upcall launch
- code. Production of a userland test program (not a full thread
- scheduler). Resolution of some of the more glaring
- incompatibilities (e.g. the scheduler) in a backwards compatible
- manner. (i.e. if there are no multi threaded processes on a
- system it should behave the same as now (and be as
- reliable)).</p>
-
- <p>Criteria for knowing when we have reached Milestone 3 is the
- ability for a simple process on an unloaded system to perform a
- series of blocking syscalls reliably. e.g. open 2 sockets, and
- send data on one, after having done a read on another, and then
- 'respond' in like manner..</p>

- <p>The project has moved forward on JDK 1.3.1 development this
- month, with the release of two more patchsets. The team is
- reasonably confident that the latest patchset is a stable release
- of the core JDK 1.3.1 tools and classes, when the default "green"
- threads subsystem is used. This is mostly thanks to hard work by
- Fuyuhiko Maruyama to stabilize and fix the code. Bill Huey has
- also been progressing with his work on the "native" threads
- subsystem, although this hasn't yet reached the stability of
- "green" threads. Another (arguably the) major highlight of the
- latest patchset was the integration of NetBSD support by Scott
- Bartram and Alistair Crooks (the latter of NetBSD packages fame).
- Hopefully OpenBSD support will follow, making it truly a united
- BSD Java Project.</p>

- <p>Alright folks, I finally got off my butt last night and put
- together a roadmap for the migration to the new rc.d init scripts
- that were imported from NetBSD a long time ago and just sat in
- the tree.</p>
-
- <p>M1 (Patch included)
- <br />
-
- Setup infrastructure
- <br />
-
- Make rcorder compile
- <br />
-
- Hook rc.subr into the distribution (and mergemaster)
- <br />
-
- Hook rcorder into the world
- <br />
-
- Add toggle in rc.conf to switch between rc_ng and current boot
- scripts</p>
-
- <p>M2
- <br />
-
- Get FreeBSD to boot with the new boot scripts
- <br />
-
- Rewrite the /etc/rc.d scripts to work with FreeBSD</p>
-
- <p>M3
- <br />
-
- Add some FreeBSD specific support into rc.subr</p>
-
- <p>M4
- <br />
-
- Add true dependency checking to the infrastructure so that
- starting nfsd will start mountd and rpcbind
- <br />
-
- add support into rc.subr
- <br />
-
- Add dependencies into rc.d scripts</p>
-
- <p>I'd like a couple of people to take a look at this and then
- I'll submit a pr for it if there aren't too many objections. I'm
- expecting M2 to run into quite a bikeshed, but hey, I got my nice
- shiny asbestos back from the cleaners.</p>

- <p>The FreeBSD C99/POSIX Conformance Project aims to implement
- all requirements of the C99 Standard and the latest 1003.1-200x
- POSIX draft (currently Draft 7). In cases where aspects of the
- standard cannot be followed, those aspects will be documented in
- the c99(7) or posix(7) manuals. It is also an aim of this project
- to implement regression tests to ensure correctness whenever
- possible.</p>
-
- <p>Patches that implement the &lt;stdint.h&gt; and
- &lt;inttypes.h&gt; headers, and modifications to printf(3) have
- been developed and will be committed shortly. They will allow us
- to use some of the new types C99 introduces, such as intmax_t and
- the printf(3) conversion specifier "%j".</p>

- <p>Some progress has been made on the proc locking this month.
- Also, a new LOCK_DEBUG macro was defined to allow some locking
- infrastructure to be more efficient. Kernels now only include the
- filenames of files calling mutex, sx, or semaphore lock
- operations if the filenames are needed. Also, mutex operations
- are no longer inlined if any debugging options are turned on. The
- ucred API was also overhauled to be more locking friendly. A
- group has also started investigating the tty subsystem to design
- and possibly implement a locking strategy.</p>
