FreeBSD Status Report
Introduction
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.
This year's EuroBSDCon 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 BSDCan in Ottawa - AsiaBSDCon
will take place in Tokyo at the begining of March.
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.
Thanks to all the reporters for the excellent work! We hope you enjoy
reading.

Analyze and Improve the Interrupt Handling Infrastructure
URL: http://wikitest.freebsd.org/Interrupts
Contact: Paolo Pisati <pisati@FreeBSD.org>
Contact: John Baldwin <jhb@FreeBSD.org>
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:
* Feedback from filters (the system finally knows if any handler has
serviced an interrupt or not, and can react consequently).
* Lower latency/overhead for shared interrupt line.
* Previous experiments with interrupt filtering showed an increase
in performance against the plain ithread model
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

AsiaBSDCon 2007
URL: http://www.asiabsdcon.org/
Contact: Hiroki Sato <hrs@freebsd.org>
Contact: George Neville-Neil <gnn@freebsd.org>
Contact: <secretary@asiabsdcon.org>
Web site is up and we're soliciting papers and presentations. Some
tutorials are already scheduled. Email secretary@asibsdcon.org if you
have questions or submissions.
Open tasks:
1. Send in more papers!
_________________________________________________________________
Bridge Spanning Tree Protocol Improvements
Contact: Andrew Thompson <thompsa@FreeBSD.org>
Work is almost finished to implement the Rapid Spanning Tree Protocol
(RSTP) which supersedes Spanning Tree Protocol (STP). RSTP has a much
faster link failover time of around one second compared to 30-60
seconds for STP, this is very important on modern networks. The code
will be posted shortly for testing and feedback.
_________________________________________________________________
BSDCan 2007
URL: http://www.bsdcan.org/
Contact: Dan Langille <dan@langille.org>
The dates for BSDCan 2007 has been set: 11-12 May 2007. As is usual,
BSDCan will be held at University of Ottawa, with two days of
tutorials prior to the conference starting.
The call for papers will go out in mid December. Start thinking about
your submissions now!
_________________________________________________________________
Bundled PXE Installer
URL: http://wikitest.freebsd.org/MarkusBoelter
Contact: Markus Boelter <m@FreeBSD.org>
Contact: Paul Saab <ps@FreeBSD.org>
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.
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.
Thanks to the people at the FreeBSD Project and Google for the really,
really great time!

Chinese (Simplified) Project
URL: http://cnsnap.cn.FreeBSD.org/zh_CN/
URL: http://cnsnap.cn.FreeBSD.org/doc/zh_CN.GB2312/
Contact: Xin LI <delphij@FreeBSD.org>
In the previous quarter we primarily focused on overall quality of the
translation rather than just increasing the number of translations,
and we have strived to make sure that these translated stuff are
up-to-date with their English revisions. Also, we have merged the
translated website into the central repository.
In the next quarter we will focus on developing documentation that
will help to attract more developers.
Open tasks:
1. Translate more development related documentation.
2. Review more of the currently translated documentation.
_________________________________________________________________
CPU Microcode Update Software
Contact: Stanislav Sedov <stas@FreeBSD.org>
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.
Thanks to John Baldwin, Kostik Belousov, John-Mark Gurney and Divacky
Roman for helping during development.
Open tasks:
1. Perform testing on the AMD64-based systems.
2. Write manpage.
3. Code cleanup/checks.
_________________________________________________________________
CScout on the FreeBSD Source Code Base
URL: http://wikitest.freebsd.org/CScout
Contact: Diomidis Spinellis <dds@FreeBSD.org>
CScout is a refactoring editor and source code browser for collections
of C code. The aim of the project is to make it easy for FreeBSD
developers to use CScout and to improve the FreeBSD source code
quality through CScout-based queries and refactorings.
CScout was first applied to the FreeBSD kernel in 2003. Its
application at that point involved substantial tinkering with the
build system. The version released in October 2006 makes the running
of CScout on the three Tier-1 architectures a fairly straightforward
procedure. The current version can also draw a number of call graphs;
this might help developers better understand foreign code.
Open tasks:
1. Use CScout to locate problematic code areas (for example unused or
too liberaly visible objects).
2. Use CScout to globaly rename identifiers in a more consistent
fashion.
3. Apply CScout to the userland code.
4. Identify CScout extensions that would help us improve the quality
of our code.
5. Arrange for the continous availability of a live CScout kernel
session on the current version of the source code.
_________________________________________________________________
DTrace
Contact: John Birrell <jb@freebsd.org>
Progress this month has been limited due to my sea-change, moving
house to the country.
Sun's OpenSolaris developers have followed through and released the
DTrace test suite as part of the OpenSolaris distribution.
jkoshy@'s work on libbsdelf is nearing feature completion for DTrace
and will make life easier in FreeBSD for DTrace, given that we have
more architectures to support than Sun has.
The FreeBSD project has made available a dual processor AMD64 machine
for DTrace porting.
I am currently working through the diffs between the DTrace project in
P4 and -current, committing files to -current if they are ready,
_________________________________________________________________
Embedded FreeBSD
URL: http://www.embeddedfreebsd.org/
Contact: George Neville-Neil <gnn@freebsd.org>
Moved the HTML pages into the project CVS tree.
Open tasks:
1. Setup the web site to be served from projects CVS so that it can
be updated by others.
2. Complete the ARM port.
3. Work on the MIPS port.
4. Update the documentation to include common tasks for embedded
engineers.
_________________________________________________________________
Enlightenment DR17 support in the ports tree
Contact: Stanislav Sedov <stas@FreeBSD.org>
Integration of the new innovative e17 window manager into the ports
tree is almost completed. A lot of new e17-related applications was
ported, all old ports were updated to the latest stable cvs snapshot.
The special framework (bsd.efl.mk) was created to support the whole
thing and simplify the creation of dependent ports. I'll commit the
changes in the days before the ports freeze.
Thanks to Sergey Matveychuk (sem@) for providing a machine to place
CVS snapshots on. Without his help it will be impossible.
Open tasks:
1. Port Entrance (xdm-like app, but very appealing).
2. Port Net and Wlan e17 module.
3. Develop FreeBSD-specific e17 apps/modules to use The Ports
Collection, system configs, etc.

URL: http://www.eurobsdcon.org/register/
Contact: EuroBSDCon Organizing Committee <info@eurobsdcon.org>
EuroBSDCon 2006 is taking place in Milan (Italy), from the 10th to the
12th of November.
EuroBSDCon represents the biggest gathering for BSD developers from
the old continent, as well as users and passionates from around the
World. It is also a chance to share experiences, know-how, and
cultures.
The program is rich in talks about FreeBSD, with topics ranging from
"How the FreeBSD ports collection works" to "Interrupt Filtering in
FreeBSD". This means that both the novice and the hacker can enjoy the
conference.
Registration is open. The EuroBSDCon Organizing Committee hopes to see
you in Milan.

FAST_IPSEC Upgrade
URL: www.freebsd.org/~gnn/fast_ipv6.patch
Contact: George Neville-Neil <gnn@freebsd.org>
Contact: Bjoern Zeeb <bz@freebsd.org>
First working version of code. Does not pass all TAHI tests, but does
pass packets correctly and does not panic.
Open tasks:
1. More testing of the patch needed.

FreeBSD Multimedia Resources List
URL: http://www.mavetju.org/unix/multimedia.php
URL: http://www.mavetju.org/unix/multimedia-rss.php
Contact: Edwin Groothuis <edwin@FreeBSD.org>
I have setup the FreeBSD Multimedia Resources List, a one-stop-shop
for FreeBSD related podcasts, vodcasts and audio/video resources.
Hopefully this list will make it easier for people to find and keep up
to date with these recordings. The overview is available as a normal
HTML page and as an XML/RSS feed.
The ultimate goal is to have this list to reside under the
www.FreeBSD.org umbrella.

Contact: Security Team <security-team@FreeBSD.org>
In the time since the last status report, six security advisories have
been issued concerning problems in the base system of FreeBSD; of
these, five problems were in "contributed" code, while one was in code
maintained within FreeBSD. The Vulnerabilities and Exposures Markup
Language (VuXML) document has continued to be updated by the Security
Team and Ports Committers documenting new vulnerabilities in the
FreeBSD Ports Collection; since the last status report, 57 new entries
have been added, bringing the total up to 814.
The following FreeBSD releases are supported by the FreeBSD Security
Team: FreeBSD 4.11, FreeBSD 5.3, FreeBSD 5.4, FreeBSD 5.5, FreeBSD
6.0, and FreeBSD 6.1. The respective End of Life dates of 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 the end of November
2006 (or possibly a short time thereafter in order to allow time for
upgrades to the upcoming FreeBSD 6.2).

FreeBSD/arm on Atmel AT91RM9200
Contact: Warner Losh <imp@freebsd.org>
Contact: Olivier Houchard <cognet@freebsd.org>
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.
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.
The port will be included in forth coming commercial products.
Open tasks:
1. Add support for other members of the AT91 family of arm9
processors.
2. Finish support for AT45D* flash parts.
3. Finish support for USB ports
4. Write support for USB Device functionality

Contact: FreeSBIE Staff <staff@FreeSBIE.org>
Contact: Matteo Riondato <matteo@FreeBSD.org>
FreeSBIE is a FreeBSD based LiveCD.
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.
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.
Open tasks:
1. Test the released ISO in preparation for the release.
2. Suggest software to include in the ISO.
3. Submit a simple and clear but complete fluxbox configuration.

FreshPorts
URL: http://www.freshports.org/
Contact: Dan Langille <dan@langille.org>
The new 2U server mentioned in the last report now has a collection of
Raptor drives in a RAID-10 configuration. Thanks to very generous
donations from the community, I purchased eight of these drives at
very good prices. The server will be deployed in the next few weeks.
There has been quite a bit of work since the last report in June. Some
highlights include:
* New news feed formats, including newsfeeds for your watch list.
* Better pages caching for faster response.
* Sanity Test Failures now available online.
* Ability to search for all commits (ports, doc, src, etc) under a
given point in the tree.
For more detail, please review the FreshPorts Blog .

Contact: Pawel Jakub Dawidek <pjd@FreeBSD.org>
GJournal seems to be finished. I fixed the last serious bug and it is
now stable and reliable in our tests. I'm planning to commit it really
soon now.

Contact: Ulf Lilleengen <lulf@pvv.ntnu.no>
I thought that since I sent a status report the last time, I might as
well send one now.
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.
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.
I've created a patch of all my work that is not in HEAD yet here (this
is a snapshot of my developement branch, so how thing's are done might
be changed quite fast):
http://folk.ntnu.no/lulf/patches/freebsd/gvinum/gvinum_all_current.dif
f
Be aware that a there will probably be bugs in the code, so don't use
it in production yet!
Thanks to Greg Lehey for offering to help me on getting this into CVS,
and all feedback on this has been good.
Open tasks:
1. Remaining components, mirror, stripe and some info commands.

Gvirstor
URL: http://wiki.freebsd.org/gvirstor
Contact: Ivan Voras <ivoras@freebsd.org>
Gvirstor is a GEOM class providing virtual ("overcommit") storage
devices larger than physical available storage, with possibility to
add physical storage on-line when the need arises. Current status is
that it's done and waiting commit to HEAD, scheduled for some time
after 6.2 is released.
Open tasks:
1. The project is in need of testing! If you have the equipment and
time, please give it a try so possible bugs can be fixed before it
goes into -CURRENT.

Highly improved implementations of sendfile(2), sosend_*() and
soreceive_stream()
URL:
http://lists.freebsd.org/pipermail/freebsd-current/2006-September/0659
97.html
URL:
http://lists.freebsd.org/pipermail/freebsd-current/2006-September/0661
99.html
URL:
http://people.freebsd.org/~andre/sendfile+sosend+soreceive-20061006.di
ff
Contact: Andre Oppermann <andre@freebsd.org>
The addition of TSO (TCP Segmentation Offload) has highlighted some
shortcomings in the sendfile(2) and sosend_*() kernel implementations.
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.
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).
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().
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).
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.
The patches are scheduled to be committed to FreeBSD-current at end of
October or early November 2006.
This work was sponsored by the TCP/IP Optimization Fundraiser 2005.

Hungarian translation of the webpages
URL: http://gabor.t-hosting.hu/data/hu/
Contact: G=E1bor K=F6vesd=E1n <gabor@FreeBSD.org>
Since the last status report, there has been a lot of progress. I
investigated a lot of charset issues and found out that HTML tidy
breaks some entities when using iso-8859-2, so HTML tidy had to be
disabled for Hungarian pages.
Open tasks:
1. Translate 4 pages.
2. Review, fix typos and improve the wording where necessary.

Improving FreeBSD Ports Collection Infrastructure
URL: http://wikitest.freebsd.org/G%C3%A1borK%C3%B6vesd%C3%A1n
Contact: G=E1bor K=F6vesd=E1n <gabor@FreeBSD.org>
Contact: Erwin Lansing <erwin@FreeBSD.org>
During the Google Summer of Code 2006, G=E1bor worked on several ideas
to improve the ports infrastructure:
1. New handling for i386 binary ports.
2. Cleanup: use ECHO_CMD and ECHO_MSG in bsd.port.mk properly.
3. Add a basic infrastructure support for debugging.
4. Installing ports with different destination (DESTDIR macro).
5. Cleanup: Move fetch shell scripts out of bsd.port.mk.
6. Make ports respect CC and CFLAGS.
7. Cross-compiling Ports.
8. Plist generator tool.
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. G=E1bor 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.

IPv6 Stack Vulnerabilities
URL: http://wikitest.freebsd.org/ClementLecigne
URL: http://pcs.sf.net
Contact: George Neville-Neil <gnn@FreeBSD.org>
Contact: Clement Lecigne <clem1@FreeBSD.org>
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.
All of the code from the project, including the tools, is on line and
is described in the paper.
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.

iSCSI Initiator
URL: ftp://ftp.cs.huji.ac.il/users/danny/freebsd/iscsi-17.5.tar.bz2=20
Contact: Damiel Braniss <danny@cs.huji.ac.il>
This iSCSI initiator kernel module and its companion control program
are still under development, but the main parts are working.
Open tasks:
1. Network Disconnect Recovery.
2. Sysctl Interface and Instrumentation.
3. Rewrite the userland side of iscontrol.

Jail Resource Limits
URL: http://wikitest.freebsd.org/JailResourceLimits
Contact: Chris Jones <cdjones@freebsd.org>
Contact: Kip Macy <kmacy@freebsd.org>
We now have support for limiting CPU and memory use in jails. This
allows fairer sharing of a systems' resources between divergent uses
by preventing one jail from monopolizing the available memory and CPU
time, if other users and jails have processes to run.
The code is currently available as patches against RELENG_6, and Chris
is in the process of applying it to -CURRENT. More details can be
found at JailResourceLimits on the wiki.
Open tasks:
1. Port patches against -CURRENT.

Contact: Joseph Koshy <jkoshy@FreeBSD.org>
Libelf is a BSD-licensed library for ELF parsing & manipulation
implementing the SysV/SVR4 (g)ELF[3] API.
Current status: Implementation of the library is nearly complete. A
TET-based test suite for the API is being worked on.
Open tasks:
1. Reviewers are needed for the code and the test suite. If you have
extensions to the stock SysV/SVR4 ELF(3) API that you would like
to see in -lelf, please send Joseph an email.

MMC/SD Support
Contact: Warner Losh <imp@freebsd.org>
Contact: Bernd Walter <tisco@freebsd.org>
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.
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.
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.
Please see the open tasks list.
Open tasks:
1. Write sdhci driver, and integrate it into the current stack.
2. Add support for hot plugging of cards.
3. Add support for MMC cards (SD cards were the first target).
4. Expand SD support to include SDIO cards as well as the new SDHC
standard cards.
5. Export stats via sysctl for each of the cards that are found as a
debugging and usage monitoring aid.
6. Add support for reading/writing multiple blocks at a time to
improve performance.
7. Implement any other host controller.
8. Add proper support for timeouts.

Nss-LDAP importing and nsswitch subsystem improvement
URL: http://wikitest.freebsd.org/MichaelBushkov
URL: http://wikitest.freebsd.org/LdapCachedOriginalProposal
URL: http://wikitest.freebsd.org/LdapCachedDetailedDescription
Contact: Michael Bushkov <bushman@FreeBSD.org>
Contact: Hajimu UMEMOTO <ume@FreeBSD.org>
The Project consisted of five parts:
1. 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.
2. 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.
3. 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 flexiable. 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.
4. 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.
5. 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.
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.

OCaml language support in ports

ocaml.mk?rev=3D1.3&content-type=3Dtext/plain
Contact: Stanislav Sedov <stas@FreeBSD.org>
There were a number of OCaml ports in our tree, and each of them was
doing the same work by maintaining OCaml ld.conf in the correct state,
installing/removing their files/entries etc. To simplify the task of
OCaml-language ports creationm the special framework (bsd.ocamk.mk)
was developed and most of the ports was 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.

OpenBSD dhclient
Contact: Brooks Davis <brooks@FreeBSD.org>
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.

Porting Xen to FreeBSD

Contact: Jue Yuan <yuanjue@FreeBSD.org>
As a participant of Google's Summer of Code 2006, I am focusing on
porting Xen to FreeBSD these months. The result of this summer's work
include a domU kernel that could be used for installation, a guide for
getting started with FreeBSD on Xen, and some other trivial
improvements. But there are still a lot of work needing to be done in
this area, e.g, the long-expeted dom0 support. So I will continue my
work here and try to keep up with the update of Xen itself.
Open tasks:
1. dom0 support is the most urgent

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.

Ports Collection

/
URL: http://people.freebsd.org/~fenner/portsurvey/
URL: http://portsmon.FreeBSD.org/index.html
URL: http://www.freebsd.org/portmgr/index.html
URL: http://tinderbox.marcuscom.com/
Contact: Mark Linimon <linimon@FreeBSD.org>
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.
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.
Seven sets of changes have been added to the infrastructure, mostly
refactoring and bugfixing.
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.
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.
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.
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.
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.
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.
linimon@ did another pass through resetting inactive maintainers.
Another list is waiting in the wings.
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.
We have added 4 new committers since the last report.
Open tasks:
1. We still need help getting back to our modern low of 500 PRs.
2. We have nearly 4400 unmaintained ports (see, for instance, the
list on portsmon ). 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.
3. 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.
4. 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.

extending the kernel to get access to all the information, a private
MIB was designed in order to be able to monitor multiple bridges
supported by FreeBSD. The kernel part has already been committed to
-CURRENT (thanks to thompsa@), for -STABLE a patch is available (see
the wiki), code has already been reviewed.
SoC 2005 work on SNMP client tools is now available too via port

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.
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.
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.
Open tasks:
1. Have a look at the sound related entries on the ideas list.
2. sndctl(1): tool to control non-mixer parts of the sound system
(e.g. spdif switching, virtual-3D effects) by an user (instead of
the sysctl approach in -current); pcmplay(1), pcmrec(1),
pcmutil(1).
3. Plugable FEEDER infrastructure. For ease of debugging various
feeder stuff and/or as userland library and test suite.
4. Extend the wiki page.

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.
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.

Contact: Colin Percival <cperciva@FreeBSD.org>
I spent the months of May through August working on improving
Portsnap, FreeBSD Update, and devoting more time to my (continuing)
role as Security Officer. FreeBSD Update is now part of the FreeBSD
base system and is fully supported by the FreeBSD Security Team;
updates are currently only being built for the i386 architecture, but
AMD64 updates will become available soon.
In an attempt to reduce the number of people running out of date (and
unsupported) FreeBSD releases, I wrote an automatic binary upgrade
script for upgrading systems from FreeBSD 6.0 to FreeBSD 6.1; I will
be releasing a new script for upgrading to FreeBSD 6.2-(RC*|RELEASE)
soon (possibly before this status report is published).
Further improvements to Portsnap are still ongoing.

It isn't clear whether or not I will have time to implement full
logical domaining support before the APIs become publicly available.
Testing indicates that substantial work will be needed before FreeBSD

Open tasks:
1. Random testing and bug fixes.
2. Import and extend improved mutex profiling support.
3. Virtual network and virtual disk device drivers for logical

Contact: Wayne Salamon <wsalamon@FreeBSD.org>
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:
* 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.
* Significant enhancements to the FreeBSD Handbook chapter on Audit.
* 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.
* Kqueue support for audit pipes.
* Robustness improvements in the presence of low disk space
conditions.
* Support for system call capture on additional platforms, such as
ppc and ia64.
* Improved support for very large audit record sizes (as required
for extensive execve support).
* id(1) now supports a -A argument to query audit state for the
process.
* An audit_warn(5) event for trail rotation, which can be used for
archiving, reduction, and other administrative activities.
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.
Open tasks:
1. Continue expanding auditing of syscall arguments.
2. Continue expanding auditing of administrative tools.
3. More testing!
4. Continue to explore improvements of the administrative model for
audit trails, etc.

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.
These changes are scheduled to be backported to FreeBSD 6-STABLE
shortly after FreeBSD 6.2-RELEASE is published to appear in upcoming
FreeBSD 6.3 early next year.
This work was sponsored by the TCP/IP Optimization Fundraiser 2005.

Contact: Roman Divacky <rdivacky@FreeBSD.org>
Contact: Emulation Mailinglist <emulation@FreeBSD.org>
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.
"Intron" submitted an implementation for the linux aio syscalls. His
work has been committed to the Perforce repository.
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).
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.

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

Xen Port
Contact: Kip Macy <kmacy@FreeBSD.org>
Work on Xen support has slowly been continuing in perforce. The SOC
student fixed several bugs and is continuing to work on it. Someone is
needed who has the time to complete dom0 support and shepherd it
production level stability.
Sufficient interest has been expressed in it that it probably makes
sense to check it in to public CVS so that more people can try it out.
Time permitting, I will bring it up to date and check it in the next
month.
Open tasks:
1. dom0 support.
2. General testing and bug fixing.
