May-June 2004 Status Report


   This installment of the Bi-Monthly Status Report is a few days late,
   but I'm pleased to say that it is chocked full of over 30 articles.
   May and June were yet again busy months; the Netperf project passed
   major milestones and can now be run with the debug.mpsafenet tunable
   turned on from sources in CVS. The ARM, MIPS, and PPC ports saw quite
   a bit of progress, as did several other SMPng and Netgraph projects.
   FreeBSD 5.3 is just around the corner, so don't hesitate to grab a
   snapshot and test the progress!

   On a more serious note, it's very important to remember that code
   freeze for FreeBSD 5.3 will happen on August 15, 2004. This is only a
   few weeks away and there is still a lot to do. The TODO list for the
   release can be found at . If you are looking for a way to contribute
   to the release, this TODO list has several items that are in urgent
   and in need of attention. Testing is also very important. The tree has
   had some stability stability problems in the past few weeks, but there
   are work-arounds that should allow everyone to continue testing and
   using FreeBSD. We absolutely must have FreeBSD 5.3 be a rock-solid
   release, so every little bit of contributed effort helps!

Bluetooth stack for FreeBSD (Netgraph implementation)

   Contact: Maksim Yevmenkin <m_evmenkin at yahoo.com>

   Bluetooth code was marked as non-i386 specific. It is now possible to
   build it on all supported platforms. Please help with testing. Other
   then this there was not much progress during last few months. I've
   been very busy with Real Life.

ALTQ import

   URL: http://www.csl.sony.co.jp/person/kjc/kjc/software.html#ALTQ
   URL: http://www.rofug.ro/projects/freebsd-altq/
   URL: http://kerneltrap.org/node.php?id=505
   URL: http://people.freebsd.org/~mlaier/ALTQ_driver/

   Contact: Max Laier <mlaier at FreeBSD.org>

   The ALTQ framework is part of KAME for more than 4 years and has been
   adopted by Net- and OpenBSD since more than 3 years. It provides means
   of managing outgoing packets to do QoS and bandwidth limitations.
   OpenBSD developed a different way to interact with ALTQ using pf,
   which was adopted by KAME as the "default for everyday use".

   The Romanian FreeBSD Users Group has had a project to work towards
   integration of ALTQ into FreeBSD, which provided a very good starting
   point for the final import. The import only provides the "pf mode"
   configuration and classification API as the older ALTQ3 API does not
   suit to our SMP approach.

   A reworked configuration API (decoupled from pf) is in the making as
   are additional driver modifications. Both should be done before
   5-STABLE is branched, although additional drivers can be imported
   during the lifetime of 5-STABLE as well.

Buf Junta project

   Contact: Poul-Henning Kamp <phk at FreeBSD.org>

   The buf-junta project is underway, I am trying to bisect the code such
   that we get a struct bufobj which is the handle and method carrier for
   a buffer-cache object. All vnodes contain a bufobj, but as filesystems
   get migrated to GEOM backing, bufobj's will exist which do not have an
   associated vnode. The work is ongoing.

CAM Lockdown

   Contact: Scott Long <scottl at freebsd.org>

   Not much coding has taken place on this lately, with the recent focus
   being on refining the design. We are currently investigating per-CPU
   completion queues and threads in order to reduce locks and increase
   concurrency. Also reviewing the BSD/OS CAM lockdown to see what ideas
   can be shared. Work should hopefully puck back up in late July.
   Development is taking place in the FreeBSD Perforce repository under
   the //depot/projects/scottl-camlock/... branch for now.

Cronyx Adapters Drivers

   URL: http://www.cronyx.ru/hardware/wan.html

   Contact: Roman Kurakin <rik at FreeBSD.org>

   cp(4) driver for Cronyx Tau-PCI was added. Cronyx Tau-PCI is family of
   synchronous WAN adapters with various set of interfaces such as V.35,
   RS-232, RS-530(449), X.21, E1, E3, T3, STS-1. This is a third family
   of Cronyx adapters that is supported by FreeBSD now. Now all three
   drivers cx(4), ctau(4) and cp(4) are on both major branches (HEAD and

   Busdma conversion was recently finished. Current work is concentrated
   on locking both for adapters drivers and for sppp (see my other report
   for additional information).

EuroBSDCon 2004 registration now open

   URL: http://www.eurobsdcon2004.de/

   Contact: Patrick M. Hausen <hausen at punkt.de>

   Registration for EuroBSDCon 2004 taking place in Karlsruhe, Germany,
   from Oct. 29th to 31st has just opened. An early bird discount will be
   offered to all registering until Aug. 15th. Please see the conference
   website for details.

FreeBSD Brazilian Documentation Project

   URL: http://doc.fugspbr.org
   URL: http://lists.fugspbr.org/listinfo.cgi/doc-fugspbr.org
   URL: http://developer.berlios.de/projects/doc-br/

   Contact: DOC-BR Discussion List <doc at fugspbr.org>

   The FreeBSD Brazilian Documentation Project is an effort of the
   Brazilian FreeBSD Users Group (FUG-BR) to translate the available
   documentation to pt_BR. We are proud to announce that we've finished
   the Handbook and FDP Primer translation and they are being revised.
   Both should be integrated to the FreeBSD CVS repository shortly.

   There are many other articles being translated and their status can be
   checked at our website. If you want to help please create an account
   at BerliOS, since our CVS repository is being hosted there, and
   contact us through our mailing list. Any help is welcome!

FreeBSD Dutch Documentation Project

   URL: http://www.evilcoder.org/freebsd_html
   URL: http://www.evilcoder.org/freebsd/handbook.tbz
   URL: http://www.evilcoder.org/freebsd/html.tbz

   Contact: Remko Lodder <remko at elvandar.org>

   The FreeBSD Dutch Documentation project is a ongoing project
   translating the FreeBSD handbook {and others} to the dutch language.
   We are still on the look for translators and people that are willing
   to check the current html documentation. If you are interested,
   contact me at the email address shown above. We currently are reading
   for some checkups and then insert the first documents into the
   documentation tree.

FreeBSD Handbook, 3rd Edition, Volume II: Administrator Guide

   URL: http://www.freebsd.org/docproj/handbook3.html

   Contact: Murray Stokely <murray at FreeBSD.org>

   The Third Edition of the FreeBSD Handbook has been split into two
   volumes. The first volume, the User Guide, has been published. Work is
   progressing on the second volume. The following chapters are included
   in the second volume : advanced-networking, network-servers, config,
   boot, cutting-edge, disks, l10n, mac, mail, ppp-and-slip, security,
   serialcomms, users, vinum, eresources, bibliography, mirrors. Please
   see the Task List for information about what work remains to be done.
   In addition to technical and grammatical review, a number of HTML
   output assumptions in the document need to be corrected.

FreeBSD ports monitoring system

   URL: http://portsmon.firepipe.net/index.html

   Contact: Mark Linimon <linimon_at_lonesome_dot_com>

   The system continues to function well. The accuracy of the automatic
   classification algorithm has been improved by assigning a higher
   priority to port names found in pieces of Makefiles.

   Several bugs had to be fixed due to the transition from bento to
   pointyhat. For about two weeks the URLs to the build errors were
   wrong. This has now been corrected (but note that some of the
   pointyhat summary pages themselves still show the broken links.)

   A report was added to show only PRs in the 'feedback' state, so that
   committers can focus on maintainer and/or responsible timeouts. (As a
   reminder, the policy is 2 weeks). Another report on 'ports that are in
   ports/MOVED, but still exist' has also been added to the Anomalies
   page. Sometimes these are actual errors but not always.

   Here are my latest observations about the trends in ports PRs:
     * We were (very briefly) down to 650 ports PRs. From looking at the
       graphs, this appears to be the lowest number since 2001. This is
       despite the fact that between the two time periods the number of
       ports had increased 70%.
     * We have made a little bit of progress on the number of PRs which
       apply to existing ports and have been assigned to a FreeBSD
       committer, from 400 to around 350. This is partly due to some
       committers going through the database, putting old PRs into the
       'feedback' state, and then later invoking the 'maintainer timeout'
       rule mentioned above. (In some cases the PRs are now too old to
       still apply, and those are just closed.)
     * A few maintainers are currently responsible for one-third of those
       350. Please, if you feel that you are over committed, consider
       asking for new volunteers to maintain these ports.
     * In terms of build errors, there is some new breakage from the
       preliminary testing with gcc3.4, which is even stricter with
       respect to the code it will accept than was gcc3.3. Many of these
       errors are shown as 'unknown' by the classification script. I have
       submitted a patch to fix this.
     * The majority of the build errors are still due to compilation
       problems, primarily from the gcc upgrades. Since FreeBSD tends to
       be at the forefront of gcc adaptation, this is to be expected, but
       IMHO we should really try to fix as many of these as possible
       before 5.3 is released.
     * 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". Here is the entire list; the
       individual bars are clickable.

FreeBSD profile.sh

   URL: https://projects.fsck.ch/profile/

   Contact: Tobias Roth <ports at fsck.ch>

   FreeBSD profile.sh is an enhancement to the FreeBSD 5 rcng boot
   system, targeted at laptops. One can configure multiple network
   environments (eg, home, work, university). After this initial
   configuration, the laptop detects automatically in what environment it
   is started and configures itself accordingly. Not only network
   settings, but almost everything from under /etc can be configured per
   environment. It is also possible to suspend the machine in one
   environment and wake it up in a different one, and reconfiguration
   will happen automatically.


   Contact: Olivier Houchard <cognet at FreeBSD.org>
   Not much to report, Xscale support is in progress, and should boot at
   least single user really soon on an Intel IQ31244

   Evaluation board.

FreeBSD/MIPS Status Report

   URL: http://www.FreeBSD.org/projects/mips/
   URL: http://www.mdstud.chalmers.se/~md1gavan/mips64emul/

   Contact: Juli Mallett <jmallett at FreeBSD.org>

   In the past two months, opportunities to perform a good chunk of work
   on FreeBSD/MIPS have arisen and significant issues with context
   switching, clocks, interrupts, and kernel virtual memory have been
   resolved. A number of issues with caches were fixed, however those are
   far from complete and at last check, there were issues when running
   cached which would prevent booting sometimes. Due to toolchain issues
   in progress, current kernels are no longer bootable on real hardware.

   A 64-bit MIPS emulator has arisen giving the ability to test and debug
   in an emulator, and much testing has taken place in it. It has been
   added to the FreeBSD ports tree, and the port will be actively
   tracking the main codebase as possible. In general, FreeBSD/MIPS
   kernels should run fine in it.

   Before toolchain and cache issues, the first kernel threads would run,
   busses and some devices would attach, and the system would boot to a
   mountroot prompt.

HP Network Scanjet 5

   URL: http://berklix.com/scanjet/

   Contact: Julian Stacey <jhs at FreeBSD.org>

   HP Network Scanjet 5 can unobtrusively run FreeBSD inside the scanner.
   Those who miss their Unix at work can have a FreeBSD box, un-noticed &
   un-challenged by blinkered managers who block any non Microsoft PC in
   the building. http://berklix.com/scanjet/

i386 Interrupt Code & PCI Interrupt Routing

   Contact: John Baldwin <jhb at FreeBSD.org>

   Support for programming the polarity and trigger mode of interrupt
   sources at runtime was added. This includes a mini-driver for the ELCR
   register used to control the configuration for ISA and EISA
   interrupts. The atpic driver reprograms the ELCR as necessary, while
   the apic driver reprograms the interrupt pin associated with an
   interrupt source as necessary. The information about which
   configuration to use mostly comes from ACPI. However, non-ACPI systems
   also force any ISA interrupts used to route PCI interrupts to use
   active-low polarity and level trigger.

   Support for suspend and resume on i386 was also slightly improved.
   Suspend and resume support was added to the ELCR, $PIR, and apic

   The ACPI PCI-PCI bridge driver was fixed to fall back to the PCI-PCI
   bridge swizzle method for routing interrupts when a routing table was
   not provided by the BIOS.

   Mixed mode can now be disabled or enabled at boot time via a loader

Improved Multibyte/Wide Character Support

   Contact: Tim Robbins <tjr at FreeBSD.org>

   Many more text-processing utilities in the FreeBSD base system have
   been updated to work with multibyte characters, including comm, cut,
   expand, fold, join, paste, unexpand, and uniq. New versions of GNU
   grep and GNU sort (from coreutils) have been imported, together with
   multibyte support patches from developers at IBM and Red Hat.

   Future work will focus on modifying the regular expression functions
   to work with multibyte characters, improving performance of the C
   library routines, and updating the remaining utilities (sed and tr are
   two important ones still remaining).

IPFilter Upgraded to 3.4.35

   URL: http://coombs.anu.edu.au/~avalon/ip-filter.html

   Contact: Darren Reed <darrenr at FreeBSD.org>

   IPFilter has been upgraded in both FreeBSD-current and 4-STABLE (post
   4.10) from version 3.4.31 to 3.4.35.

KDE on FreeBSD

   URL: http://freebsd.kde.org

   Contact: Michael Nottebrock <lofi at FreeBSD.org>

   The work on converting the build switches/OPTIONS currently present in
   the ports of the main KDE modules into separate ports in order to make
   packages available for the software/features they provide is
   progressing. Porting of KOffice 1.3.2 are nearly completed. The
   swedish FreeBSD snapshot server , operated and maintained by members
   of the KDE/FreeBSD team, is back up and running at full steam.
   Additional amd64 hardware has been added and amd64 snapshots will be
   available soon.


   URL: http://www.FreeBSD.org/~nsouch/kgi4BSD

   Contact: Nicholas Souchu <nsouch at FreeBSD.org>

   KGI is going slowly but surely. The port of the KGI/Linux accel to
   FreeBSD is in progress. It's no more than a double buffering API for
   graphic command passing to the HW engine.

   Most of the work in the past months was about console management and
   more especially dual head console. Otherwise a new driver building
   tree is now ready to compile Linux and FreeBSD drivers in the same

   Documentation about KGI design is in progress.

Low-overhead performance monitoring for FreeBSD


   Contact: Joseph Koshy <jkoshy at FreeBSD.org>

   The current design attempts to support both per-process and
   system-wide statistical profiling and per-process "virtual"
   performance counters. The userland API libpmc(3) is somewhat stable
   now, but the kernel module's design is being redone to handle MP
   better. Initial development is targeting the AMD Athlon CPUs, but the
   intent is to support all the CPUs that FreeBSD runs on.

   An early prototype is available under Perforce [under

Network interface naming changes

   Contact: Brooks Davis <brooks at FreeBSD.org>

   An enhanced network interface cloning API has been committed. It
   allows interfaces to support more complex names then the current name#
   style. This functionality has been used to enable interesting cloners
   like auto-configuring vlan interfaces. Other features include locking
   of cloner structures and the ability of drivers to reject destroy

   Work on userland support for this functionality is ongoing.

Network Stack Locking

   URL: http://www.freebsd.org/smp/
   URL: http://www.watson.org/~robert/freebsd/netperf/

   Contact: Robert Watson <rwatson at FreeBSD.org>

   This project is aimed at converting the FreeBSD network stack from
   running under the single Giant kernel lock to permitting it to run in
   a fully parallel manner on multiple CPUs (i.e., a fully threaded
   network stack). This will improve performance/latency through
   reentrancy and preemption on single-processor machines, and also on
   multi-processor machines by permitting real parallelism in the
   processing of network traffic. As of FreeBSD 5.2, it was possible to
   run low level network functions, as well as the IP filtering and
   forwarding plane, without the Giant lock, as well as "process to
   completion" in the interrupt handler. This permitted both inbound and
   outbound traffic to run in parallel across multiple interfaces and

   Work continues to improve the maturity and completeness of the locking
   (and performance) of the network stack for 5.3. The network stack
   development branch has been updated to the latest CVS HEAD, as well as
   the following and more. Many but not all of these changes have been
   merged to the FreeBSD CVS tree as of the writing of this report.
   Complete details and more minor changes are documented in the README
   file on the netperf web page.
     * Addition of hard-coded WITNESS lock orders for socket-related
       locks, route locks, interface locks, file descriptor locks, SLIP,
       and PCB locks for various protocols (UDP, TCP, UNIX domain
       sockets). (Merged)
     * Modifed MAC Framework to use inpcbs as the source for mbuf labels
       rather than reaching up to the socket layer, avoiding the
       additional acquisition of socket locks. Locked access to so_label
       and so_peerlabel using the socket lock throughout; assert socket
       lock in the MAC Framework where depended on. MAC Framework now
       makes a copy of the socket label before externalizing to prevent a
       copyout while holding the label lock (and potentially seeing an
       inconsistent label). (Merged)
     * Extensive annotation of locking state throughout the network
       stack, especially relating to sockets.
     * Several locking fixes for ng_base.c, the basic Netgraph
       infrastructure. (Merged)
     * Global accept filter list locking, especially during registration.
       (Partially merged)
     * Revise locking in socket state transition helpers, such as
       soisconnecting(), soisconnected(), etc, to simplify lock handling.
     * Fix bugs in netatalk DDP locking, merge all netatalk locking to
       CVS. (Merged)
     * soref() socket locking assertions and associated fixes. (Merged)
     * Fifofs now uses its own mutex instead of the vnode interlock to
       synchronize fifo operations, avoiding lock order issues with
       socket buffer locking. (Merged)
     * Cleanup of locking related to file descriptor close and Giant
       requirements. Experimentation with reducing locking here.
     * Review and fix several instances of socket locking in the TCP
       code. (Merged)
     * NFS server locking merged to FreeBSD CVS. (Merged)
     * Accept locking merged to rwatson_netperf, and to FreeBSD CVS. A
       new global mutex, accept_mtx, now protects all socket related
       accept queue and state fields (SS_COMP, SS_INCOMP), and flags
       relating to accept are moved from the generic so_state field to
       so_qstate. accept1() rearranged, as with sonewconn() as a result,
       and a file descriptor leak fixed. Close a variety of races in
       socket referencing during accept. soabort() and other partially
       connected socket related functions updated to take locking into
       account. (Merged)
     * Issue associated with non-atomic setting of SS_NBIO in fifofs
       resolved by adding MSG_NBIO. (Merged)
     * Several flags from so_state moved to sb_state so they can be
       locked properly using the socket buffer mutex. (Merged)
     * Socket locks are now not held over calls into the protocol
       preventing many lock order issues between socket and protocol
       locks, and avoiding a substantial amount of conditional locking.
     * mbuma, the UMA-based mbuf allocator, is merged to CVS. This
       reduces the kernel to one widely used memory allocator, improves
       performance, and allows memory from mbufs to be reclaimed and
       reused for other types of storage when pressure lowers. (Merged)
     * sb_flags now properly locked. (Merged)
     * Global MAC label ifnet lock introduced to protect labels on
       network interfaces. (Merged)
     * Rewrites of parts of soreceive() and sosend() to improve MP safety
       merged to CVS, including modifications to make sure socket buffer
       cache state is consistent when locks are released.
       sockbuf_pushsync() added to guarantee consistency of cached
       pointers. (Merged)
     * UNIX domain socket locking revised to use a subsystem lock due to
       inconsistencies in lock order and inconsistent coverage ofunpcb
       fields. Cleanup of global variable locking in UNIX domain sockets,
       Giant handling when entering VFS. All UNIX domain socket locking
       merged to CVS. (Merged)
     * netisr dispatch introduced in the routing code such that routing
       socket message delivery is performed asynchronously from routing
       events to avoid lock order issues. (Merged)
     * IGMP and multicast locking merged to CVS. (Merged)
     * Cleanup of lasting recursive Giant acquisition left over from
       forwarding/bridging plane only locking. (Merged)
     * ALTQ imported into the FreeBSD in a locked state. (Merged)
     * Conditional locking in sbdrop(), sbdroprecord(), sbrelease(),
       sbflush(), spappend(), sbappendstream(), sbappendrecord(),
       sbinsertoob(), sbappendaddr(), sbappendcontrol() eliminated.
     * Some cleanup of IP stack management ioctls and lock order issues.
     * Cleanup and annotation of sorflush() use of a temporary stack held
       socket buffer during flush. (Merged)
     * Substantial cleanup of socket wakeup mechanisms to drop locks in
       advance of wakeup, avoid holding locks over upcalls, and
       assertions of proper lock state. (Merged)
     * With the integration of revised ifnet cloning, cloning data
       structures are now better locked. (Merged)
     * Socket locking for portalfs. (Merged)
     * Global so_global_mtx introduced to protect generation numbers and
       socket counts. (Merged)
     * KAME IPSEC and FAST_IPSEC now use rawcb_mtx to protect raw socket
       list integration. More work required here. (Merged)
     * Socket locking around SO_SNDLOWAT and SO_RCVLOWAT. (Merged)
     * soreserve() and sbreserve() reformulation to improve locking and
       consistency. Similar cleanup in the use of reservation functions
       in tcp_mss(). (Merged)
     * Locking cost reduction in sbappend*(). (Merged)
     * Global locking for a number of Netgraph modules, including
       ng_iface, ng_ppp, ng_socket, ng_pppoe, ng_frame_relay, ng_tty,
       ng_eiface. (Merged)
     * IPv6 inpcb locking. Resulting cleanup of inpcb locking assertions,
       and enabling of inpcb locking assertions by default even with IPv6
       compiled in.
     * if_xl now MPSAFE. (Merged)
     * soreceive() non-inline OOB support placed in its own function.
     * NFS client socket locking. (Merged)
     * SLIP now uses a asynchronous task queue to prevent Giant-free
       entrance of the TTY code.
     * E-mail sent to current@ providing Giant-free operation guidelines
       and details.

Packet Filter - pf

   URL: http://www.benzedrine.cx/pf.html

   Contact: Max Laier <mlaier at FreeBSD.org>
   Contact: Daniel Hartmeier <dhartmei at FreeBSD.org>

   We imported pf as of OpenBSD 3.5 stable on June, 17th which will be
   the base for 5-STABLE pf (according to the current schedule). The most
   important improvement in this release is the new interface handling
   which makes it possible to write pf rule sets for hot-pluggable
   devices and pseudo cloning devices, before they exist. The import of
   the ALTQ framework enabled us to finally provide the related pf
   functions as well.

   Before 5-STABLE we will import some bug fixes from OpenBSD-current,
   which have not been merged to their stable branch, as well as some
   FreeBSD specific features. The planned ALTQ API make-over will also
   affect pf.

   We are (desperately) looking for non-manpage documentation for FreeBSD
   pf and somebody to write it. Few things have changed so a port of the
   excellent "PF FAQ" on the OpenBSD homepage should be fitting. There
   are, however, a couple of points that need conversion. A simple
   tutorial how to setup a NAT gateway with pf would also help. The
   in-kernel NAT engine is very easy to use, we should tell people about
   this alternative. This is even more true since the pf module now plugs
   into GENERIC without modifications.

PowerPC Port

   Contact: Peter Grehan <grehan at FreeBSD.org>

   The port has been moving along steadily. There have been reports of
   buildworld running natively. Works is almost complete on make release
   so there will be bootable CD images in the near future.

Project Mini-Evil

   Contact: Scott Long <scottl at freebsd.org>

   Project Mini-Evil is an attempt to extend Bill Paul's 'Project Evil'
   Windows NDIS wrapper layer to the SCSI MiniPort and StorePort layers.
   While drivers exist for most storage controllers that are on the
   market today, many companies are integrating software RAID into their
   products but not providing any source code or design specs. Instead of
   constantly reverse-engineering these raid layers and attempting to
   shoehorn them into the ata-raid driver, Project Mini-Evil will run the
   Windows drivers directly. It will hopefully also run most any
   SCSI/ATA/RAID drivers that conform to the SCSI Miniport or Storeport

   Work on this project is split between making the NDIS wrapper code
   more general and implementing the new APIs. Development is taking
   place in the FreeBSD Perforce repository under the
   //depot/projects/sonofevil/... branch.

SMPng Status Report

   Not a lot happened on the SMPng front outside of the work on locking
   the network stack (which is a large amount of work). The priorities of
   the various software interrupt threads were corrected and locking for
   taskqueues was improved. The return value of the sema_timedwait()
   function was adjusted to be more consistent with cv_timedwait(). A
   small fix was made to the sleepqueue code to shorten the amount of
   time that a sleepqueue chain lock is held when waking up threads. Some
   simple debug code for profiling the hash tables used in the sleep
   queue and turnstile code was added. This will allow developers to
   measure the impact of any tweaks to the hash table sizes or the hash

Sync protocols (Netgraph and SPPP)

   Currently I work on two directions: if_spppfr.c and sppp locking (on
   behalf of netperf). At the moment of writing this sppp locking is not
   ready yet. But it would be ready in couple of days. Also you may find
   as a part of this work some user space fixes for rwatson netperf code
   (Only that I was able to catch while world compilation. If you know
   some others let me know and I'll try to fix them too).

   Since sppp code is quite big and state machine is very complicated, it
   would be difficult to test all code paths. I will glad to get any help
   in testing all this stuff. More tester more probability to test all
   possible cases.

   Work on FRF.12 (ng_frf12) is frozen since of low interest and lack of
   time. Current state of stable code: support of FRF.12 End-to-End
   fragmentation. Support of FRF.12 Interface (UNI and NNI) fragmentation
   is not tested.

TTY subsystem realignment

   Contact: Poul-Henning Kamp <phk at FreeBSD.org>

   An effort to get the tty subsystem out from under Giant has morphed
   into an more general effort to eliminate a lot of code which have been
   improperly copy & pasted into device drivers. In an ideal world, tty
   drivers would never get near a cdevsw, but since some drivers are more
   than just tty drivers (for instance sync) a more sensible compromise
   must be reached. The work is ongoing.

Various GEOM classes and geom(8) utility

   Contact: Pawel Jakub Dawidek <pjd at FreeBSD.org>

   I'm working on various GEOM classes. Some of them are already
   committed and ready for use (GATE, CONCAT, STRIPE, LABEL, NOP). The
   MIRROR class is finished in 90% and will be committed in very near
   future. Next I want to work on RAID3 and RAID5 implementations.
   Userland utility to control GEOM classes (geom(8)) is already in the

VuXML and portaudit

   Contact: Tom Rhodes <trhodes at FreeBSD.org>

   The portaudit utility is currently an add-on to FreeBSD designed to
   give administrators and users a heads up with regards to security
   vulnerabilities in third party software. The VuXML database keeps a
   record of these security vulnerabilities along with internal security
   holes. When installed, the portaudit utility periodically downloads a
   database with known issues and checks all installed ports or packages
   against it; should it find vulnerable software installed the
   administrator or user is notified during the daily run output of the
   periodic scripts.

   These utilities are considered to be of production quality and
   discussion is taking place over whether or not they should be included
   as part of the base system. All ports committers are urged to add
   entries when when a vulnerability is discovered; any questions may be
   sent to eik@ or myself.
