FreeBSD Quarterly Status Report January-March, 2012

FreeBSD Quarterly Status Report January-March, 2012

Introduction

   This report covers FreeBSD-related projects between January and March
   2012. It is the first of the four reports planned for 2012. This
   quarter was highlighted by releasing the next major version of FreeBSD,
   9.0, which was finally released in the beginning of January 2012. The
   FreeBSD Project dedicates the FreeBSD 9.0-RELEASE to the memory of
   Dennis M. Ritchie, one of the founding fathers of the UNIXŽ operating
   system. Our release engineering team has been also busy with
   preparation of the 8.3-RELEASE, which was publicly announced in April.

   Thanks to all the reporters for the excellent work! This report
   contains 27 entries and we hope you enjoy reading it.

   Please note that the deadline for submissions covering the period
   between April and June 2012 is July 15th, 2012.

A New linux_base Port Based Upon CentOS

   Contact: Alexander Leidinger <netchild <at> FreeBSD.org>

   We got a PR with a linux_based port which is based upon CentOS 6.
   Currently this can only be used as a test environment, as it depends
   upon a more recent linux kernel version, than the linuxulator provides.

   As of this writing, I'm in the process of preparing a commit of this
   port.

Open tasks:

    1. Repocopy by portmgr.
    2. Add conflicts in other linux_base ports.
    3. Commit the CentOS based one.
    4. Some cleanup.
     __________________________________________________________________

Atheros 802.11n Support

   URL: http://wiki.FreeBSD.org/AdrianChadd/AtherosTxAgg
   URL: http://wiki.FreeBSD.org/dev/ath(4)

   Contact: Adrian Chadd <adrian <at> FreeBSD.org>

   802.11n station and hostap support is now fully functional, sans
   correct hostap side power saving. TX aggregation and TX BAR handling is
   implemented.

   Station chip power saving is not implemented at all yet, it's not in
   the scope of this work.

   Testers should disable bgscan (-bgscan) as scan/bgscan will simply drop
   any traffic in the TX/RX queues, causing potential traffic stalls.

Open tasks:

    1. Fix up hostap side power save handling.
    2. Implement filtered frames support in the driver.
    3. Fix scan/bgscan to correctly buffer and retransmit frames when
       going off channel, so frames are not just "dropped" - this causes
       issues in the aggregation sessions and may cause traffic stalls.
    4. Test/fix any issues with adhoc 802.11n support.

BSD-licensed sort Utility (GNU sort Replacement)

   URL: http://www.FreeBSD.org/cgi/cvsweb.cgi/ports/textproc/bsdsort/
   URL:
   http://pubs.opengroup.org/onlinepubs/9699919799/utilities/sort.html

   Contact: Oleg Moskalenko <oleg.moskalenko <at> citrix.com>
   Contact: Gábor Kövesdán <gabor <at> FreeBSD.org>

   Currently the BSD sort reached usable stable stage. It is stable, it is
   as fast as the GNU sort, and it supports multi-byte locales (this is
   something that GNU sort does not do correctly). BSD sort has all
   features of GNU sort 5.3.0 (version included into FreeBSD) with some
   extra features and bug fixes.

Open tasks:

    1. Add BSD sort into HEAD as an alternative, installed as bsdsort. If
       proven to work as expected, change it to the default sort version
       and remove GNU sort.
    2. Investigate the possibility of a multi-threaded sort implementation
       and implement it, if it proves more efficient.
    3. Upgrade BSD sort features to include some obscure new features in
       the latest GNU sort version 8.15.

Clang Replacing GCC in the Base System

   URL: http://wiki.FreeBSD.org/BuildingFreeBSDWithClang

   Contact: Brooks Davis <brooks <at> FreeBSD.org>
   Contact: David Chisnall <theraven <at> FreeBSD.org>
   Contact: Dimitry Andric <dim <at> FreeBSD.org>
   Contact: Ed Schouten <ed <at> FreeBSD.org>
   Contact: Pawel Worach <pawel.worach <at> gmail.com>
   Contact: Roman Divacky <rdivacky <at> FreeBSD.org>

   Both FreeBSD 10.0-CURRENT and 9.0-STABLE now have Clang 3.0 release
   installed by default. At least on 10.0-CURRENT, both world and the
   GENERIC kernel can be completely built without any -Werror warnings.
   This may not be the case for all custom kernel configurations yet.

   As of r231057, there is a WITH_CLANG_EXTRAS option for src.conf(5),
   which will enable a number of additional LLVM and Clang tools, such as
   'llc' and 'opt'. These tools are mainly useful for people that want to
   manipulate LLVM bitcode (.bc) and LLVM assembly language (.ll) files,
   or want to tinker with LLVM and Clang themselves.

   Also, as of r232322, there is a WITH_CLANG_IS_CC option for
   src.conf(5), which will install Clang as /usr/bin/cc, /usr/bin/c++ and
   /usr/bin/cpp, making it the default system compiler. Unless you also
   use the WITHOUT_GCC option, gcc will still be available as
   /usr/bin/gcc, /usr/bin/g++ and /usr/bin/gcpp.

   The intent is to switch on this option by default rather sooner than
   later, so we can start preparing for shipping 10.0-RELEASE with Clang
   as as the default system compiler, and deprecating gcc.

   In other news, we will import a newer snapshot of Clang soon, since
   upstream LLVM/Clang has already announced their 3.1 release will be
   branched April 16, 2012. Most likely, the actual 3.1 release will be
   follow a few weeks later, after which we will do another import.

   Last but not least, there are many ports people working on making our
   ports compile properly with Clang. Fixes are checked in on a very
   regular basis now, and full exp-runs with Clang are also done fairly
   regularly. Of course, there are always a few difficult cases,
   especially with very old software that will not even compile with newer
   versions of gcc, let alone clang.

Open tasks:

    1. One of the most important tasks at the moment is to actually build
       and run your entire FreeBSD system with Clang, as much as possible.
       Any compile-time or run-time problems should be reported to the
       appropriate mailing list, or filed as a PR. If you have patches
       and/or workarounds, that would be even better.
    2. Clang should have gotten better support for cross-compiling after
       3.0, so as soon as a 3.1 version is imported, we will need to look
       at ways to get the FreeBSD world and kernels to cross-compile. This
       is mainly of use for ARM and MIPS, which are architectures you
       usually do not want to build natively on.
    3. Help to make unwilling ports build with Clang is always needed, and
       greatly appreciated. Please mail the maintainer of your favorite
       port with patches, or file PRs.

DTrace Probes for the linuxulator

   Contact: Alexander Leidinger <netchild <at> FreeBSD.org>

   Recently DTrace in the kernel was improved to be able to load kernel
   modules with static dtrace providers after the dtrace modules. This
   allows me to commit my linuxulator specific static provider work to
   -CURRENT.

   Together with the linuxulator DTrace probes I developed some D scripts
   to check various code paths in the linuxulator. Those scripts check
   various error cases which may be interesting to verify userland code,
   but also linuxulator internals like locks.

   As of this writing I'm in the process of updating a test machine to a
   more recent -current to prepare the commit.
     __________________________________________________________________

FreeBSD Services Control

   URL: http://people.FreeBSD.org/~trhodes/fsc/

   Contact: Tom Rhodes <trhodes <at> FreeBSD.org>

   After a while of moving and getting a new job, I finally got back to
   this project (also thanks to several submissions by Julian Fagir), a
   new version has been uploaded along with a short description page. The
   current version supports more options, a configuration file, and
   updated rc.d script. It also includes manual page updates and an
   optional debugging mode.
     __________________________________________________________________

FreeBSD/arm on Various TI Boards

   URL: http://svnweb.FreeBSD.org/base/projects/armv6/sys/arm/ti/

   Contact: Ben Gray <bgray <at> FreeBSD.org>
   Contact: Olivier Houchard <cognet <at> FreeBSD.org>
   Contact: Damjan Marion <dmarion <at> FreeBSD.org>
   Contact: Oleksandr Tymoshenko <gonzo <at> FreeBSD.org>

   The goal of this project is to get FreeBSD running on various popular
   boards that use TI-based SoCs like OMAP3, OMAP4, AM335x. Project covers
   some ARM generic Cortex-A components: GIC (Generic Interrupt
   Controller), PL310 L2 Cache Controller and SCU.

   PandaBoard (TI OMAP4430) and PandaBoard ES (OMAP4460) Dual core ARM
   Cortex-A9 board support includes: USB, onboard Ethernet over USB, GPIO,
   I2C and MMC/SD card drivers. Board works in multiuser mode over NFS
   root.

   BeagleBone (TI AM3358/AM3359) single core ARM Cortex-A8 based board
   support currently includes: Ethernet, L2 cache, GPIO, I2C. Board works
   in multiuser mode over NFS root.

Open tasks:

    1. Completing missing peripherals: DMA, SPI, MMC/SD, Video, Audio.
    2. Completing SMP support and testing.
    3. Importing BeagleBoard (OMAP3) code to SVN.
    4. Improving overall stability and performance.

   Contact: Piotr Ziecik <kosmo <at> semihalf.com>

   This work is bringing up the FreeBSD on Freescale QorIQ Data Path
   Acceleration Architecture (DPAA) system-on-chips along with device
   drivers for integrated peripherals. Since the last status report, the
   following support has been added:
     * Ethernet (full network functionality using Regular Mode of DPAA
       infrastructure)
     * QorIQ P5020 SoC (e5500 core in legacy 32-bit mode)
     * P5020 QorIQ Development System support
     * Initial support for Enhanced SDHC

   The next step is:
     * e5500 core in native 64-bit mode

GNU-Free C++11 Stack

   Contact: David Chisnall <theraven <at> FreeBSD.org>

   Since the last status report, the combination of libc++ and libcxxrt
   has received some additional testing and gained some new features
   including support for ARM EABI. With clang 3.1, we now pass all of the
   C++11 atomics tests.

   The xlocale implementation (required for libc++) has been tested with a
   variety of ports that were originally written for the Darwin
   implementation, and bugs that this testing uncovered have been fixed.
   This should be released in 9.1.

   In -CURRENT, we are now building libsupc++ as a shared library. This
   provides the ABI layer and building it as a shared library means that
   we can replace it with libcxxrt easily. If you are running -CURRENT,
   please try using libmap.conf to enable libcxxrt instead of libsupc++.

   If libstdc++ is using libcxxrt, you can now link against both libraries
   that are using libstdc++ and libc++, making the migration slightly
   easier, although you cannot pass STL objects between libraries using
   different STL versions.

   We still need a replacement for some parts of libgcc_s and for the
   linker, but we're on track for a BSD licensed C++ stack in 10.0.

Open tasks:

    1. Test ports with libc++. Hopefully most will Just Work, but others
       may need patches or have a hard dependency on libstdc++.
    2. Enable building libc++ by default. This is dependent upon building
       with clang, because the version of gcc in the base system does not
       support C++11 and so can not be used to build libc++.
    3. Removing libstdc++ from the base system and making it available
       through ports for backwards compatibility.

Growing filesystems online

   Contact: Edward Tomasz Napierala <trasz <at> FreeBSD.org>

   The goal of this project is to make it possible to grow a filesystem,
   both UFS and ZFS, while it's mounted read-write. This includes changes
   to both filesystems, GEOM infrastructure, and the da(4) driver. For
   testing purposes, I've also added resizing to mdconfig(8) and
   implemented LUN resizing in CAM Target Layer.

   From the system administrator point of view, this makes it possible to
   resize mounted partition using gpart(8) and then resize the filesystem
   on it using growfs(8) - all without unmounting it first; especially
   useful if it's a root filesystem.

   All the functionality works and is in the process of being refined,
   reviewed and merged to HEAD.

   This project is sponsored by The FreeBSD Foundation.

Open tasks:

    1. The write suspension infrastructure (/dev/ufssuspend) implemented
       to make resizing possible makes it also possible to implement
       online tunefs(8) and fsck(8).
    2. Right now, there is no way for a GEOM class to veto resizing --
       classes are notified about resize and they can either adapt, or
       wither. Many classes store their metadata in the last sector,
       though, so resizing a partition containing e.g. gmirror will make
       it inoperable. It would be nice if geom_mirror(4) could veto
       resizing, so the administrator attempting to shoot himself in the
       foot would get a warning.

HDMI/DisplayPort Audio Support in HDA Sound Driver (snd_hda)

   Contact: Alexander Motin <mav <at> FreeBSD.org>

   snd_hda(4) driver got number of improvements to better support
   HDMI/DisplayPort audio, such as:
     * Added fetching EDID-Like Data from the CODEC and video driver,
       describing audio capabilities of the display device.
     * Added setting HDMI/DP-specific CODEC options, such as number of
       channels, speakers configuration and channels mapping.
     * Added support for more multichannel formats. For HDMI and
       DisplayPort device now supported: 2.0, 2.1, 3.0, 3.1, 4.0, 4.1,
       5.0, 5.1, 6.0, 6.1, 7.0 and 7.1 channels.
     * Added support for compressed streams passthrough with data rate
       6.144 - 24Mbps, such as DTS-HD Master Audio or Dolby TrueHD.
     * Added support for HDA bus multiplexing to handle higher data rates
       (up to 92, 184 or more Mbps, depending on hardware capabilities).
       It allows to handle several 192/24/8 LPCM playback streams
       simultaneously.

   Above functionality was successfully tested on NVIDIA GT210 and GT520
   video cards with nvidia-driver-290.10 driver. HDMI audio on older
   NVIDIA ION and Geforce 8300 boards still does not work for unknown
   reason. There are also successful reports about Intel video with latest
   KMS-based drivers. Support for ATI cards is limited to older cards,
   because video driver supporting newer cards does not support HDMI
   audio.

   The code was committed to HEAD and merged to 9-STABLE branch.

   Project sponsored by iXsystems, Inc.

Open tasks:

    1. Make better use of received EDID-Like Data.
    2. Identify and fix problem with older NVIDIA cards.

Improved hwpmc(9) Support for MIPS

   Contact: Oleksandr Tymoshenko <gonzo <at> FreeBSD.org>

   hwpmc(9) for MIPS has been reworked. The changes include:
     * msip24k code was split to CPU-specific and arch-specific parts to
       make adding support for new CPUs easier
     * Added support for Octeon PMC
     * Added sampling support for MIPS in general

IPv6 Performance Analysis

   URL: http://people.FreeBSD.org/~bz/bench/

   Contact: Bjoern A. Zeeb <bz <at> FreeBSD.org>

   IPv6 performance numbers were often seen (significantly) lower on
   FreeBSD when compared to IPv4. Continuing last years IPv6-only kernel
   efforts this project looked at various reasons for this and started
   fixing some.

   As part of the project a benchmark framework was created that could
   carry out various tests including reboots in between runs and gather
   results reproducibly without user intervention. It allows regular
   benchmarking with minimal configuration and easy future extension for
   more benchmarks.

   As a result of the initial analysis, UDP locking and route lookups were
   improved, and delayed checksumming, TSO6 and LRO support for IPv6 were
   implemented. Following this checksum "offload" for IPv6 on loopback was
   enabled and various further individual improvements, both locking and
   general code changes, as well as a reduction of the cache size
   footprint were carried out. Some of the changes were equally applied to
   IPv4.

   Performance numbers on physical and loopback interfaces are on par with
   IPv4 when using offload support with TCP/IPv6, which is a huge
   improvement. UDP and non-offload numbers on IPv6 have generally
   improved but are still lower than on IPv4 and will need future work to
   catch up with a decade of IPv4 benchmarking and code path
   optimizations. UDP IPv6 minimal size send path packets per second (pps)
   numbers however have increased beating IPv4 when sending to a local
   discard device.

   This gets us really close to being able to prefer IPv6 by default
   without causing loopback performance regressions. For physical
   interfaces, cxgb(4) in HEAD already supports IPv6 TCP offload and
   LRO/v6 support was added. To be able to get more test results on
   different hardware, both ixgbe(4) and cxgbe(4) were also updated to
   support TSO6 and LRO with IPv6.

   Some of the insights gained from this work will help upcoming
   discussions on both the lower/link-layer overhaul as well as for the
   mbuf changes to prepare our stack for more, future improvements (ahead
   of time).

   I once again want to thank the FreeBSD Foundation and iXsystems for
   their support of the project, as well as George Neville-Neil for
   providing review.

   Having set the start to close one of the biggest feature parity gaps
   left I will continue to improve IPv6 code paths and hope that we will
   see more contributions and independent results from the community as
   well soon.

Open tasks:

    1. Carefully merge code changes to SVN.
     __________________________________________________________________

isci(4) SAS Driver

   Contact: Jim Harris <jimharris <at> FreeBSD.org>

   An Intel-supported isci(4) driver, for the integrated SAS controller in
   Intel's C600 chipsets, is now available in head, stable/9, stable/8 and
   stable/7.

   The isci(4) driver will also be part of the FreeBSD 8.3 release.

KDE/FreeBSD

   URL: http://FreeBSD.kde.org
   URL: http://FreeBSD.kde.org/area51.php

   Contact: KDE FreeBSD <kde <at> FreeBSD.org>

   The team has made many releases and upstreamed many fixes and patches.
   The latest round of releases include:
     * KDE SC: 4.7.4 (in ports) and 4.8.0, 4.8.1, 4.8.2 (in area51)
     * Qt: 4.8.0, 4.8.1 (in area51)
     * PyQt: 4.9.1; SIP: 4.13.2 (in area51)
     * KDevelop: 2.3.0; KDevPlatform: 1.3.0 (in area51)
     * Calligra: 2.3.87 (in area51)
     * Amarok: 2.5.0
     * CMake: 2.8.7

   Due to the prolonged port freeze the KDE team has not been able to
   update KDE in Ports as it is considered a intrusive change.

   The team is always looking for more testers and porters so please
   contact us at kde <at> FreeBSD.org and visit our home page at
   http://FreeBSD.kde.org.

Open tasks:

    1. Testing KDE SC 4.8.2.
    2. Testing KDE PIM 4.8.2.
    3. Testing phonon-gstreamer and phonon-vlc as the phonon-xine backend
       was deprecated (but will remain in the ports for now).
    4. Testing the Calligra beta releases (in the area51 repository).

Multi-FIB: IPv6 Support and Other Enhancements

   URL: http://svnweb.FreeBSD.org/base/projects/multi-fibv6/

   Contact: Bjoern A. Zeeb <bz <at> FreeBSD.org>
   Contact: Alexander V. Chernikov <melifaro <at> FreeBSD.org>

   In 2008 the multiple forwarding information base (FIB) feature was
   introduced for IPv4 allowing up to 16 distinct forwarding ("routing")
   tables in the kernel. Thanks to the sponsorship from Cisco Systems,
   Inc. this feature is now also available for IPv6 and one of the bigger
   IPv6 feature-parity gaps is closed. The changes have been integrated to
   HEAD, were merged back to stable/9 and stable/8 and will be part of
   future releases for these branches. A backport to stable/7 is also
   available in the project branch. If more than one FIB is requested,
   IPv6 FIBs will be added along the extra IPv4 FIBs without any special
   configuration needed and programs like netstat and setfib, as well as
   ipfw, etc. were extended to seamlessly support the multi-FIB feature on
   both address families.

   Thanks to the help of Alexander V. Chernikov all usage of the multi-FIB
   feature is now using the boot-time variable rather than depending on
   the compile time option. In HEAD this now allows us you to use the
   multi-FIB feature with GENERIC kernels not needing to recompile your
   own anymore. The former kernel option can still be used to set a
   default value if desired. Otherwise the net.fibs loader tunable can be
   used to request more than one IPv6 and IPv4 FIB at boot time.

   Last, routing sockets are now aware of FIBs and will only show the
   routing messages targeted at the FIB attached to. This allows route
   monitor or routing daemons to get selective updates for just a specific
   FIB.

NAND File System, NAND Flash Framework, NAND Simulator

   URL: http://svnweb.FreeBSD.org/base/projects/nand/

   Contact: Grzegorz Bernacki <gjb <at> semihalf.com>
   Contact: Mateusz Guzik <mjg <at> semihalf.com>

   The NAND Flash stack consists of a driver framework for NAND
   controllers and memory chips, a NAND device simulator and a fault
   tolerant, log-structured file system, accompanied by tools, utilities
   and documentation.

   NAND FS support merged into "nand" project branch:
     * NAND FS filesystem
     * NAND FS userland tools

   NAND Framework and NAND simulator merged into "nand" project
   branch:
     * NAND framework: nandbus, generic nand chips drivers
     * NAND Flash controllers (NFC) drivers for NAND Simulator and Marvell
       MV-78100 (ARM)
     * NAND tool (which allows to erase, write/read pages/oob, etc.

   The next steps include:
     * Fix bugs
     * Merge into HEAD

   Work on this project is supported by the FreeBSD Foundation and Juniper
   Networks.

Perl Ports Testing

   URL: http://wiki.FreeBSD.org/Perl#Test_Dependencies

   Contact: Steve Wills <swills <at> FreeBSD.org>

   Many Perl modules in ports come with test cases included with their
   source. This project's goal is to ensure that all these tests pass.
   Significant progress has been made on this project. The change to build
   perl with -pthread was committed and no issues have been reported. Many
   ports have had missing dependencies added and/or other changes and
   approximately 90% of p5- ports pass tests. Work is being done on
   bringing testing support out of ports tinderbox.

Open tasks:

    1. Finish work on patch to bring testing support to ports.
    2. Add additional support for testing other types of ports such as
       python and ruby.

Porting DTrace to MIPS and ARM

   Contact: Oleksandr Tymoshenko <gonzo <at> FreeBSD.org>

   The major part of DTrace has been ported to MIPS platform. Supported
   ABIs: o32 and n64. n32 has not been tested yet. MIPS implementation
   passes 853 of 927 tests from DTrace test suite.

   The fbt provider and userland DTrace are not supported yet.

   The port to ARM is in progress.

   Since the last status report, there has been a significant progress in
   optimizing TRE. The multiple pattern heuristic code is mostly finished
   and it distinguishes several different cases to speed up pattern
   matching. It extracts literal fragments from the original patterns and
   uses a multiple pattern matching algorithm to find any occurrence. GNU
   grep uses the Commentz-Walter algorithm, which is an automaton-based
   algorithm, while in this project, it has been decided to use a
   Wu-Manber algorithm, which is more efficient and also easier to
   implement. In the current state, it does not work entirely yet and some
   cases, like the REG_ICASE flag are not yet covered. This is the next
   major step to complete this multiple pattern interface. In the
   development branch, BSD grep is already modified to use this new
   interface so it can be used for testing and debugging purposes.

Open tasks:

    1. Finish multiple pattern heuristic regex matching.
    2. Implement GNU-specific regex extensions.
    3. Test standard-compliance and correct behavior.

   Contact: Devin Teske <dteske <at> FreeBSD.org>
   Contact: Ron McDowell <rcm <at> fuzzwad.org>

   Approaching 20,000 lines of sh(1) code, the bsdconfig(8) tool is
   approximately 70% complete. Upon completion of this project,
   bsdconfig(8) will represent (in conjunction with already-existing
   bsdinstall(8)) a complete set of utilities capable of purposefully
   deprecating sysinstall(8) in FreeBSD 9 and higher. This project has
   been a labor of love for Ron McDowell and I for over 90 days now and we
   are approaching the completion of this wonderful tool.

Open tasks:

    1. The "installer suite" modules for acquiring/installing binary
       packages and additional distribution sets. Startup services module.

   The Foundation sponsored AsiaBSDCon 2012 which was held in Tokyo,
   Japan, March 22-25. We were represented at SCALE on Jan 21 and NELF on
   March 17. This quarter we plan on being at ILF (Indiana LinuxFest)
   April 14th, BSDCan May 11-12, and SELF (Southeast LinuxFest) June 9.

   We are proud to be a gold sponsor of BSDCan 2012, which will be held in
   Ottawa, Canada, May 11-12. We are sponsoring 14 developers to attend
   the conference.

   We kicked off three foundation funded projects -- Growing Filesystems
   Online by Edward Tomasz Napierala, Implementing auditdistd daemon by
   Pawel Jakub Dawidek, and NAND Flash Support by Semihalf.

   We are pleased to announce the addition of George Neville-Neil to our
   board of directors. Deb Goodkin, our Director of Operations, was
   interviewed by bsdtalk.

   We announced a call for project proposals. We will accept proposals
   until April 30th. Please read Project Proposal Procedures to find out
   more.

   FreeBSD 9.0 was released and we are proud to say we funded 7 of the new
   features!

   URL: https://github.com/freebsd-haskell/hsporter/
   URL: https://github.com/freebsd-haskell/hsmtk/

   Contact: Gábor PÁLI <pgj <at> FreeBSD.org>
   Contact: Ashish SHUKLA <ashish <at> FreeBSD.org>

   We are proud announce that the FreeBSD Haskell Team has committed the
   Haskell Platform 2011.4.0.0 update, GHC 7.0.4 update, existing port
   updates, as well new port additions to FreeBSD ports repository, which
   were pending due to freeze for 9.0-RELEASE. Some of the new ports which
   were committed include Yesod, Happstack, wxHaskell, gitit, Threadscope,
   etc. and the count of Haskell ports in FreeBSD Ports tree is now almost
   300. All of these updates will be available as part of upcoming
   8.3-RELEASE.

   We started project hsporter to automate creation of new FreeBSD Haskell
   ports from .cabal file, as well as update existing ports. We also
   published scripts which we were using in the FreeBSD Haskell project
   under the project hsmtk.

Open tasks:

    1. Test GHC to work with clang/LLVM.
    2. Add an option to the lang/ghc port to be able to build it with
       already installed GHC instead of requiring a separate GHC boostrap
       tarball.
    3. Add more ports to the Ports Collection.

   Contact: Hiroki Sato <hrs <at> FreeBSD.org>
   Contact: Ryusuke Suzuki <ryusuke <at> FreeBSD.org>

   The same as before, the outdated contents in the www/ja subtree were
   updated to the latest versions in the English counterpart. The updating
   work of the outdated translations in the www/ja subtree is almost
   complete. Only the translations of the release documents for old
   releases may be outdated.

   During this period, we translated the 9.0-RELEASE announcement and
   published it in a timely manner. It seems that the Japanese version of
   the release announcement is important for Japanese people as this page
   has frequently been referenced.

   For FreeBSD Handbook, translation work of the "cutting-edge" section is
   still on-going. Some updates in the "printing" and the "linuxemu"
   section were done.

Open tasks:

    1. Further translation work of outdated documents in both
       doc/ja_JP.eucJP and www/ja.

   URL: http://www.facebook.com/portmgr

   Contact: Thomas Abthorpe <portmgr-secretary <at> FreeBSD.org>
   Contact: Port Management Team <portmgr <at> FreeBSD.org>

   The ports tree slowly climbs above 23,000 ports. The PR count still
   remains at about 1100.

   In Q1 we added 2 new committers, took in 2 commit bits for safe
   keeping, and had one committer return to ports work.

   The Ports Management team have been running -exp runs on an ongoing
   basis, verifying how base system updates may affect the ports tree, as
   well as providing QA runs for major ports updates. Of note, -exp runs
   were done for:
     * Ports validation in the FreeBSD 10 environment
     * Updates to bison, libtool and libiconv
     * Set java/opendjdk6 as default java
     * Tests with clang set as default
     * Update to devel/boost and friends
     * Update of audio/sdl and friends
     * Tests for changes in the ports licensing infrastructure
     * Update to devel/ruby1[8|9]
     * Update to postresql
     * Update to apr
     * Checks for new x11/xorg
     * Security update to security/gnutls
     * Ongoing validation of infrastructure with pkgng

   A lot of focus during this period was put into getting the ports tree
   into a ready state for FreeBSD 8.3, including preparing packages for
   the release.

   Beat Gaetzi has been doing ongoing tests with the ports tree to ensure
   a smooth transition from CVS to Subversion.

Open tasks:

    1. Looking for help getting ports to build with clang.
    2. Looking for help with Tier-2 architectures.
    3. ports broken by src changes.
    4. ports failing on pointyhat.
    5. ports failing on pointyhat-west.
    6. ports that are marked as BROKEN.
    7. When did that port break?
    8. Most ports PRs are assigned, we now need to focus on testing,
       committing and closing.

   Contact: Xin Li <delphij <at> FreeBSD.org>

   FreeNAS 8.0.4 was released last month, which marks the end of the 8.0.x
   branch in FreeNAS.

   FreeNAS 8.2.0 is in BETA currently, and will hopefully be released by
   the end of April.

   It features a number of improvements over the 8.0.x line, including
   plugin support, (the ability to run arbitrary software in jails), as
   well as better integration between command line ZFS and the GUI.

   Once 8.2.0 is out it will be quickly followed up with 8.3.0, which will
   include a number of driver updates as well as the long awaited ZFS v28.
