<title>Introduction</title>
<p>This report covers FreeBSD related projects between April and
June 2007. Again an exciting quarter for FreeBSD. In May we saw one
of the biggest developers summits to date at
<a href="http://www.bsdcan.org/2007/">BSDCan</a>
, our 25 Google Summer of Code students started working on
<a href="http://www.freebsd.org/projects/summerofcode-2007.html">
their projects</a>
- progress reports are available below, and finally the 7.0 release
cycle was started three weeks ago.</p>
<p>If your are curious about what's new in FreeBSD 7.0 we suggest
reading Ivan Voras' excellent summary at:
<a href="http://ivoras.sharanet.org/freebsd/freebsd7.html">
http://ivoras.sharanet.org/freebsd/freebsd7.html</a>
and of course these reports.</p>
<p>The next gathering of the BSD community will be at
<a href="http://2007.eurobsdcon.org/">EuroBSDCon in Copenhagen</a>
, September 14-15. More details about the conference and the
developer summit are available in the respective reports below.</p>
<p>Thanks to all the reporters for the excellent work! We hope you
enjoy reading.</p>

<body>
<p>Mpd-4.2 has been released. It includes many new features,
performance improvements and fixes.</p>
<p>The most significant and unique new feature is a link repeater
functionality. It allows mpd to accept incoming connection of any
supported type and forward it out as same or different type
outgoing connection. As example, this functionality allows mpd to
implement real LAC with accepting incoming PPPoE connection from
client and forwarding it using L2TP tunnel to LNS. All other
software L2TP implementations I know is only a LAC emulators
without real incoming calls forwarding abilities.</p>
<p>Also mpd-4.2 presents:</p>
<ul>
<li>PPTP listening on multiple different IPs,</li>
<li>L2TP tunnel authentication with shared secret,</li>
<li>fast traffic filtering, shaping and rate-limiting using
ng_bpf and ng_car,</li>
<li>new 'ext-auth' auth backend as full-featured local
alternative to 'radius-auth',</li>
<li>NetFlow generation for both incoming and outgoing packets
same time.</li>
</ul>
<p>Replacing external ifconfig and route calls with their
internal implementations and other optimizations in 4.2 gave
significant performance boost in session management. Newly
implemented overload protection mechanism partially drops
incoming connection requests for periods of critical load by
monitoring daemon's internal message queue. As result, simple
2GHz P4 system is now able to accept, authenticate and completely
process spike of 1000 concurrent PPPoE connections in just a 30
seconds.</p>
</body>
<help>
<task>Implement dynamic link/bundle creation.</task>
<task>Auth proxying support in repeater mode. It is required for
some LAC/PAC and Tunnel Switching Aggregator (TSA) setups.</task>
<task>Remove static phys - link - bundle and phys - repeater
relations. Implement ability to differentiate incoming
connections processing depending on user login, domain and/or
other parameters.</task>

<p>The basic idea behind this project is to implement secure and
reliable log file shipping to remote hosts. While the
implementation focuses on audit logs, the goal is to build tools
that will make it possible to perform distributed logging for any
application by using a simple API and linking with a shared
library.</p>

<body>
<p>OpenBSD includes sysctl hw.sensors framework since 2003; since
2005 the frameworks supports raid drives and most known i2c
sensors; since 2006 the framework is redesigned with a sensor
device concept in mind to accommodate continued growth. Consists
of kernel api, sysctl(3)/sysctl(8), sensorsd(8), ntpd(8),
systat(1), ports/sysutils/symon and 51 drivers as of
2007-07-07.</p>
<p>This GSoC2007 project is to port the underpinnings of this
unified hardware monitoring interface to FreeBSD. Whilst it won't
be possible to port all of the drivers due to architecture
differences, we aim at porting all other parts of the framework
and accompanying userland utilities.</p>
<p>At this time, lm(4) at isa and some kernel api have already
been ported. The next big step is to complete sysctl(3) glue code
so that further work on porting userland utilities could be
accomplished. Details about sysctl are being discussed on
arch@.</p>

<title>Porting Linux KVM to FreeBSD</title>

<p>The Linux kernel-based Virtual Machine (KVM) is a mechanism to
exploit the virtualization extensions present in some modern CPUs
(e.g., Intel VT and AMD-V). Virtualization extensions let
ordinary processes execute a subset of privileged instructions in
a controlled way at near-native speed. This in turn may improve
the performance of system emulators such as qemu, xen, vmware,
vkernel, User Mode Linux (UML), etc.</p>
<p>This project consists in porting to FreeBSD the Linux KVM,
implemented as a loadable module, lkvm.ko. We use the approach in
ports/devel/linux-kmod-compat to reuse the original Linux source
code almost unmodified. We will also port a modified version of
qemu which exploits the facilities made available by the Linux
KVM to speed up emulation.</p>
<p>The URL above links to progress report detailing the exact
project goals, milestones reached, and commit log details.</p>
<p>As of end of June 2007, we have mainly extended
linux-kmod-compat to support the kernel API used by the Linux KVM
code. The required functions have been implemented at various
degrees, from simple stubs to fully functional ones. We have also
imported the modified qemu and the libraries that are used to
build the Linux KVM userspace client. In the second half of the
SoC work we plan to complete the implementation of the kernel API
and have a fully functional Linux KVM module, together with its
client (qemu).</p>

<p>This project aims to create a multicast DNS daemon and service
discovery utilities suitable for the base system. Multicast DNS
is a part of Zero Configuration Networking (Zeroconf) and
provides the ability to address hosts using DNS-like names
without the need of an existing (unicast), managed DNS server.
Work on the responder daemon is well underway and the only large
missing piece of the puzzle is a way for local clients to do
queries. The code can be found in the p4 branch
projects/soc2007/fli-mdns_sd if anyone would like to give it a
spin, even though it's incomplete. The project plan can be found
on the wiki.</p>

user and a back end to interact with freebsd-update. The back and
front ends are able to communicate with each other using an XML
protocol. The GUI is almost at the point it can take a command
from the user and send it to the back end. The back end is able
to detect when updates are ready.</p>

<p>The sixth EuroBSDCon will take place at Symbion in Copenhagen,
Denmark on Friday the 14th and Saturday 15th of September
2007.</p>
<p>The programme is ready and online at the webpage. Registration
is open. Details about tutorials and Legoland trip are ready too.
<br />
The keynote will be John Hartman: Real men's pipes</p>
<p>If you share a room with friends at the hostel, then lodging
is really inexpensive, and the lounge has high speed Internet
access. Staying at the hostel is of course optional, and the area
has several hotels.</p>
<p>KD85.com and O'Reilly will each have a booth at the
conference.</p>
<p>We are still looking for more sponsors.</p>
<p>A public IRC channel #eurobsdcon on EFnet has been created for
discussion and questions about the conference.</p>

<p>Tarfs is a simple tar file system implementation for
FreeBSD.</p>
<p>The current goals are:</p>
<ul>
<li>Support all standard read-only operations</li>
<li>Support large tar files (several gb's)</li>
<li>Use minimal memory</li>
<li>Allow using tar file as a root file system</li>
<li>Fast enough to actually use</li>
</ul>
<p>Here's the current state of things:</p>
<ul>
<li>Can mount most tar files</li>
<li>Can do most operations (open,lookup,stat,readdir,etc)</li>
<li>Supports large tar files (tested up to 2GB)</li>
<li>Uses a relatively small amount of memory - proportional to
number of files/dirs</li>
</ul>

the USB stack. Here is a quick list of the most important
changes:</p>
<ol>
<li>FULL speed isochronous devices over HIGH speed USB Hubs are
now fully supported. Due to various reasons the maximum
isochronous bandwidth has been limited to 6MBit/s. This limit
is tunable.</li>
<li>There is now full support for Linux USB device drivers
through a Linux USB API emulation layer.</li>
<li>Various cleanups and fixes.</li>
</ol>
<p>Markus Brueffer is still working on the USB HID parser and
support. Nothing has been committed yet.</p>
<p>If you want to test the new USB stack, checkout the USB
perforce tree or download the SVN version of the USB driver from
my USB homepage. At the moment the tarballs are a little out of
date.</p>
<p>Ideas and comments with regard to the new USB API are welcome
at freebsd-usb@FreeBSD.org .</p>

<p>Project "finstall" aims to create a next-generation FreeBSD
installer that will make use of the newest features present in
the system. The project should yield something usable for
7.0-RELEASE, but the intention is to keep it as a "second"
installer system during 7.x, alongside sysinstall. In any case,
sysinstall will be kept for architectures not supported by
finstall (e.g. all except i386 and amd64).</p>

<p>This entry was previously the Bt878 Audio Driver (aka
FusionHDTV 5 Lite driver) announcement, but as work expanded
slightly, it's a bit more generic now.</p>
<p>A few bugs in bktrau has been fixed since January. If you have
been running an earlier version, it is recommended to upgrade as
the driver could panic. The driver works with multiple cards in
the same machine (tested with two).</p>
<p>
<b>FusionHDTV 5 Lite</b>
-- Due to lack of documentation from DViCO and LG, I have copied
magic values from the Linux driver to get ATSC capturing
working.</p>
<p>
<b>ATI HDTV Wonder</b>
-- After years of trying to get into the ATI developer program,
they have finally suspended it, so no support from ATI. I have
started work on a driver, cxd, for the Conexant CX2388x based
cards. The ATI HDTV Wonder uses ATI's own demodulator, and I was
able to get it to tune, after cribbing from the Linux driver.
When capturing, I get some valid data, but not all the data. Due
to lack of support from ATI and linux-dvb the project has been
put on indefinite hold.</p>
<p>If someone has another CX2388x based card, it shouldn't be too
hard to take the driver and get it working with a different
tuner.</p>
<p>A Python module is available for both drivers/cards, along w/
a sample capture application using it. The module is now known to
work well with threads so that tuning (expensive due to i2c
ioctl's) can happen in another thread without causing program
slow down. The module is working well with a custom PVR
backend.</p>

<p>Gavin Atkinson has joined the bugbuster team via getting a
GNATS account on the FreeBSD cluster. He is following in the
footsteps of Matteo Riondato, who later graduated to a full src
commit bit. So far, he has helped close nearly 150 PRs, including
many that had become stale. Welcome!</p>
<p>Our short-term goal is to try to identify bugs that we might
be easily able to fix before the 6.3/7.0 simultaneous release. So
far, great progress has been made on ata- and usb-related
PRs.</p>
<p>The goal for the rest of this year is to generate more
developer interest in fixing bugs. To do this, we are, first,
trying to do more work on triaging PRs as they come in, to help
flag ones that seem to be valid problems (especially if they
include patches.) Secondly, we have started a new weekly periodic
posting to the freebsd-bugbusters@FreeBSD.org mailing list, which
is a short list of PRs that we feel are ready for committer
action. This posting is automatically generated from a text-file
list that we maintain.</p>
<p>We are continuing to try to manage our community's
expectations of what we can do with the incoming PRs. In
particular, we are trying to discourage submissions of the form
"I cannot get the XYZ function to work". In practice, these PRs
are not worked on. Instead, we are now encouraging these postings
to go to one of the mailing lists such as freebsd-questions@,
freebsd-x11@, and so forth. The idea is to emphasize GNATS as a
"Problem Report" method, rather than a "general FreeBSD support"
method. I feel that, otherwise, we were creating a false
expectation.</p>
<p>The overall PR count has dropped to below 5000, despite the
extra PRs still not cleared up from the ports freeze for the
xorg7.2 import. Significant progress has been made on the i386,
kern, and bin PRs, as well as PRs in the 'feedback' state. In
addition, Warner Losh has made progress on closing many of the
usb PRs.</p>

<p>The ports count is over 17,300. The PR count has been stable
at around 800; we have not quite cleared up the backlog that
showed up during the freeze to import xorg7.2.</p>
<p>There have been 4 experimental runs on the build cluster, most
notably resulting in some speedups for package registration. A
further experimental run to genericize autotools handling is in
progress.</p>
<p>One of the most sweeping ports commits to happen in years was
the upgrade of xorg from 6.9 to 7.2. This involved a complete
rework of the internals of the port, as X.org itself has
effectively pushed the responsibility for packaging to the OSes
that incorporate it. The idea was to be able for them to update
individual code (such as video drivers) without having to reroll
the entire distribution. This commit caused us to have the
longest period of preparation work, and actual tree lockdown,
that I am aware of. The commit continues to be controversial,
partly due to the fact that none of our port upgrade tools was up
to the task of doing the upgrade without manual intervention.</p>
<p>At the same time that xorg was upgraded, we moved the
installation directory from the obsolete /usr/X11R6 to our
default /usr/local. This further complicated the upgrade.</p>
<p>There have been new releases of the ports tinderbox code, the
portmaster update utility, and portupgrade.</p>
<p>GNOME was updated to 2.18.2.</p>
<p>We have added 7 new committers since the last report. We
appreciate all the new help. However, a few committers have
turned in their commit bits for safekeeping, due to lack of
time.</p>
<p>Unfortunately, Clement Laforet has also had to step down from
portmgr due to lack of time. We thank him for his help so
far.</p>
<p>Erwin, Kris and Mark met up at BSDCan and reviewed all the
portmgr-owned PRs. A large number were closed, or suspended
pending more work from the submitter. After closing the PRs that
were committed after the -exp builds, the number of portmgr owned
PRs came down to an all time low of 48 from around 70. We hope to
make further progress during the rest of the year.</p>

<p>The network stack virtualization project aims at extending the
FreeBSD kernel to maintain multiple independent instances of
networking state. This will allow for complete networking
independence between jails on a system, including giving each
jail its own firewall, virtual network interfaces, rate limiting,
routing tables, and IPSEC configuration.</p>
<p>I believe that the prototype, which is kept in sync with
FreeBSD -CURRENT, is now sufficiently stable for testing. It
virtualizes the basic INET and INET6 kernel structures and
subsystems, including IPFW and PF firewalls, and more. In the
next month I plan to have the IPSEC code fully virtualized, and
refine and document the management APIs. The short-term goal is
to deliver production-grade kernel support for virtualized
networking for FreeBSD 7.0-RELEASE (as a snap-in kernel
replacement), while continuing to keep the code in sync with
-CURRENT for possible merging at a later date.</p>

<p>IP can easily be tunneled over a plethora of network protocols
at various layers, such as IP, ICMP, UDP, TCP, DNS, HTTP, SSH.
While a direct connection may not always be possible due to a
firewall, the IP packets could be encapsulated as payload in
other protocols, which would get through. However, each such
encapsulation requires the setup of a different program and the
user has to manually probe different encapsulations to find out
which of them works in a given environment.</p>
<p>mtund is a tunneling daemon using run-time loadable plugins
for the different encapsulations. It automagically selects the
best encapsulation in each environment and fails over to another
encapsulation in case the environment changes. There already is
running code available, capable of tunneling via TCP and UDP with
a working failover mechanism. As this is a Summer of Code
project, rapid changes and addition of new features can be
expected during the summer. Please see the wiki page for more
details and up-to-date information.</p>
<p>Note that the project originally started under the name of
Super Tunnel Daemon, but was later renamed to mtund for Magic
Tunnel Daemon.</p>

to replace the global scheduler lock with a finer-grain interface
modeled on the Solaris container lock approach. This
significantly reduces contention on higher-end multiprocessor
machines.</p>

<p>SCHED_SMP is a fork of the ULE scheduler which makes use of
the new fine grain scheduler locking in 7.0-CURRENT to
significantly improve SMP performance on some workloads. It has
improved and stronger affinity, smarter CPU load balancing,
structural improvements and many sysctl tunables. This can be
considered ULE 3.0. Discussions are ongoing as to whether this
will go into 7.0 as SCHED_SMP or as SCHED_ULE in 7.0 or 7.1.</p>
<p>SCHED_ULE has had many bugfixes and performance improvements
over the 7.0 development cycle and should no longer be considered
unstable or experimental. On most workloads it significantly
outperforms SCHED_4BSD on SMP and even slightly outperforms it on
UP. There are some pathlogical workloads which exhibit as much as
a 5% performance penalty. Many thanks to Kris Kennaway and
current users for bug reports and performance testing.</p>

to select() have also been discussed on arch@ that solve

<p>Code freeze in preparation for FreeBSD 7.0 began on June 18th.
There are several large projects still being finished up as well
as some issues that resulted as "fallout" from the work done just
before the code freeze started (e.g. things resulting from the
GCC 4.2 import). A schedule for the 7.0 release has not been set
yet but the hope is that the first BETA build will be done near
the end of July with a "fairly normal" release cycle (a few BETA
builds followed by two or three RCs, each separated by around two
weeks).</p>
<p>We are planning to release FreeBSD 6.3 around the same time as
FreeBSD 7.0 is released so the release schedule for that will be
set at the same point we set the release cycle for 7.0, hopefully
late in July.</p>

<p>Support was added for two more 10gigabit network drivers and
there were major advances on improving system performance over
10g media.</p>
<p>Kip Macy committed a new driver for the Chelsio adapters. The
cxgb driver supports all current 10g adapters, as well as the new
four-port gigabit model. The cxgb driver work was supported by
Chelsio.</p>
<p>Drew Gallatin made significant improvements to the Myricom 10g
driver mxge. With these updates the driver does line rate
transfers with less system overhead.</p>
<p>Neterion contributed the nxge driver to support all their
Xframe 10Gbe Server/Storage adapters. The initial driver import
was done by Sam Leffler; a switch over to vendor support will
happen soon.</p>
<p>Jack Vogel is preparing a driver to support the latest Intel
10g hardware devices. The new driver - ixgbe - will complement
the existing ixgb driver that supports older Intel 10g cards.</p>
<p>Kip and Drew worked with other folks on performance analysis
and tuning. This work improved cpu affinity and reduced overhead
for managing network resources. Work is also underway to define a
common Large Receive Offlaod (LRO) infrastructure. LRO is
analogous to TSO on the receive side enabling drivers to receive
at near line rate with normal sized frames. This common code base
will help replace driver-specific code.</p>

<body>
<p>Just like last year I got the opportunity to work on updating
the Linuxulator to Linux version 2.6. This year I work on
finishing futexes, *at syscalls and epoll/inotify.</p>
<p>I, cooperating with Konstantin Belousov, have managed to fix
futexes to the state of passing the official futex testing
program. The fix was committed and 7.0R will ship with correct
futex implementation. Work is planned on removing Giant locking
from futexes. This only needs some careful review and
testing.</p>
<p>These days I mostly focus on *at syscalls, the patch is almost
finished for committing and I hope that it will make it into 7.0R.
As a part of this work I implemented native FreeBSD syscalls as
well. Watch arch mailing list as I post the patch there.</p>
<p>I also finished writing my master thesis describing how the
Linuxulator works and Gábor Kövesdán is working
on integrating it into official FreeBSD articles.</p>
<p>No work has happened in the epoll/inotify area but I hope to
work on it right after I finish the *at syscalls.h</p>

<p>Security Regression Test is supported by the project of Google
summer code 2007. The main objective of this stage is to test the
correctness of FreeBSD Mandatory Access Control Framework
including correctly passing the security label from userland to
kernel and non-bypassibility of Mandatory Access Control
Hooks.</p>
<p>Work performed in the last month:</p>
<ol>
<li>Constructed a pair of pseudo ethernet drivers used for
testing network related hooks. To avoid the packet go through
the lo interface, the IP address in the packet is twisted in
the driver.</li>
<li>Constructed a framework for logging Mandatory Access
Control hooks which is got called during a period of time.
<ul>
<li>In kernel, every non-null label is got externalized into
human readable string and recorded in a tail queue together
with the name of hook that got called and possible flags or
modes (etc. VREAD/VWRITE for mac_check_vnode_open hook).
There is a thread much like audit subsystem's audit_worker
logging the queue into a userspace file. The userland program
use open, ioctl and close the /dev/mactest node to trigger
and stop the logging. The logging file is truncated to zero
every time the logging mechanism is triggered.</li>
<li>In userland, a bison based parsing tool is used to parse
the logged file and reconstruct the record chain which will
be compared with testsuite supplied configuration file to
examine if expected hooks is got called and the
label/flags/modes are correct. c) The testsuite mainly
follows src/tools/regression/fstest, modified to adapt to
test Mandatory Access Control Framework and include tests for
signals</li>
</ul>
</li>
</ol>
</body>
<help>
<task>The code is quick and dirty. For example, a call to vn_open
without checking its return value which is not fault tolerance.
The coding style also needs modifications.</task>
<task>Although a test framework is completely constructed, the
detailed test cases still need to be written, the test cases
beside fstest and signal need to be add.</task>
<task>Testing of audit subsystem has not begin.</task>
<task>Other parts of Security Subsystem in FreeBSD also need

<p>General cleanups in preparation for 7.0.</p>
<p>Process audit state moved to the credential to allow it to be
accessed lock-free in most cases, as well as allowing it to be
used in asynchronous contexts.</p>
<p>OpenBSM 1.0a14 has been imported, which: fixes IPv6 endian
issues, makes OpenBSM gcc41 warnings clean, teaches
audit_submit(3) about getaudit_addr(), adds zonename tokens;
other changes since the existing CVS 1.0a12 release previously
imported include man page improvements, XML printing support,
better audit.log.5 documentation, additional 64-bit token types,
and new audit event identifiers.</p>
<p>MAC checks have been added so that MAC policies can control
use of audit system calls.</p>
<p>Additional system call arguments are now audited.</p>
<p>Audit now provides a security.audit sysctl node in order to
determine if audit support is compiled in; boot-time console
printfs have been removed.</p>
<p>"options AUDIT" is now in the 7-CURRENT GENERIC kernel, so
AUDIT support will be available out of the box in 7.0 without a
kernel recompile. Manually enabling audit support in rc.conf will
still be required. With FreeBSD 7.0, AUDIT will be a fully
supported, rather than experimental, feature.</p>

<p>The FreeBSD Foundation ended Q2 raising over $116,000. We're
almost half way to our goal of raising $250,000 this year! We
continued our mission of supporting developer communication by
helping FreeBSD developers attend BSDCan. We were also a sponsor
of BSDCan and the developer summit. We are a sponsor of
EuroBSDCon 2007 and are now accepting travel grant applications
for this conference. Foundation board members met with
representatives of companies that use or are thinking of using
FreeBSD both in the bay area and Ottawa.</p>
<p>The Foundation has negotiated a joint development agreement
with Google, Inc. to sponsor FreeBSD developer Joseph Koshy to
improve FreeBSD's HWPMC implementation, including adding
stacktrace support, and a donation of SMP hardware for future SMP
scalability work. We greatly appreciate Google's support for this
project, which will facilitate performance measurement and
optimization of both the FreeBSD operating system and
applications running on it.</p>

<p>Cleanup of MAC Framework API/KPI layers: mac.h is now just the
user and user<->kernel API; mac_framework.h is the
kernel<->MAC Framework KPI, and mac_policy.h is the MAC
Framework<->MAC policy module KPI. Along similar lines,
mac_label_get() and mac_label_set() accessor functions now allow
policies to access label data without encoding struct label
binary layout into policy modules, opening the door to more
efficient layouts. struct label is now in mac_internal.h and used
only inside the MAC Framework.</p>
<p>General MAC policy cleanup, including removing no-op entry
points and sysctls for some sample policies. mac_test(4) has been
cleaned up significantly, and counters for all entry points
added.</p>
<p>A MAC check for UNIX domain socket connect has been added.</p>
<p>MAC checks have been added so that MAC policies can control
use of audit system calls.</p>
<p>MAC checks that duplicate existing privileges but add no
additional context have been removed (such as sysarch_ioperm,
kld_unload, settime, and system_nfsd) -- checks aligned with
privileges but that do provide additional context, such as
additional arguments, have been kept.</p>
<p>The Biba and LOMAC policies now implement priv(9) checks,
differentiating between privileges that may compromise system
integrity models, and those that don't.</p>
<p>The essentially unused mnt_fslabel / mnt_label distinction has
been eliminated by moving to a single mnt_label. No functional
change to any policy.</p>
<p>Several MAC-related interfaces have been modified to
synchronize with the naming conventions present in the version of
the MAC Framework adopted in Mac OS X Leopard; significant
further changes are in the pipeline to complete this
synchronization. While it will not be possible to reuse a policy
between the two platforms without careful thinking and
modification, this makes porting much easier.</p>

<p>The custom file descriptor array lock has been replaced with
an optimized sx lock, resulting in 2x-4x improvement in MySQL
transaction rates on 8-core MySQL benchmarks. This improvement is
due to moving to shared locking for frequent fd lookup
operations, as well as significant optimization of the case where
the filedesc lock is highly contended (as occurs in the threaded
MySQL server performing constant socket I/O).</p>
<p>The custom socket buffer I/O serialization lock (sblock),
previously created by interlocking SB_WANT and SB_LOCK flags with
the socket buffer mutex, has been replaced with an optimized sx
lock, leading to a 10% performance improvement in MySQL and
PostgreSQL benchmarks on 8-core systems. As part of this change,
sx locks now have interruptible sleep primitives to allow the
SB_NOINTR flag to work properly.</p>
<p>These changes also correct a long-standing bug in socket
buffer lock contention and SB_NOWAIT reported by Isilon; a
simpler patch has been merged to 6.x to fix this bug without
merging loocking changes.</p>
<p>TCP debugging is now properly synchronized using a new
tcp_debug_mtx.</p>
<p>UMA allocation counters are now used for pipes rather than
custom atomic counters, resulting in lowered overhead for pipe
allocation and free.</p>
<p>Significant code cleanup, commenting, and in some cases
MFC'ing, has taken place with respect to the network stack and
synchronization. Additional DDB debugging commands for sockets of
various sorts have been added, allowing listing of socket state
from DDB without the use of GDB.</p>
<p>Certain non-MPSAFE subsystems have been removed or will be
removed from FreeBSD 7.0, including IPX over IP tunneling (not
general IPX/SPX support, just the tunneling over IP), KAME IPSEC
(FAST_IPSEC is MPSAFE and now now supports IPv6), i4b, netatm
(two other ATM stacks are still present), and ng_h4. Some of
these features will be reintroduced in FreeBSD 7.1, but by
removing them now, we are able to remove the NET_NEEDS_GIANT
compatibility infrastructure that significant complicates and
obfuscates the socket and network stack code.</p>

the 7.0 locking/synchronization work for the network stack is
essentially complete.</p>

<p>Further reduction of suser(9) consumers in order to attempt to
remove the suser(9) KPI for 7.0. This includes resource limits,
System V IPC, PPP, netinet port reuse, the NFS server, and
netatalk. Remove unnecessary or redundant privilege checks were
possible. UFS-privileges that apply to other file systems have
been renamed to VFS privileges.</p>
<p>All suser_cred() flags and priv_check_cred() flags are no
longer required, as SUSER_ALLOWJAIL and SUSER_RUID use are
determined entirely inside kern_jail.c and kern_priv.c and
selected based on the privilege number, not a calling context
flag. All privileges are now consistently allowed or not allowed
in jail, and consistently use the ruid or euid. We will leave the

<p>In the time since the last status report, two security
advisories have been issued concerning problems in the base
system of FreeBSD; both of these problems were in "contributed"
code maintained outside of FreeBSD. The FreeBSD Vulnerabilities
and Exposures Markup Language (VuXML) document has continued to
be updated; since the last status report, 35 new entries have
been added, bringing the total up to 925.</p>
<p>In order to improve handling of security issues in the FreeBSD
Ports Collection a new "ports-security" team has been created to
include ports committers who periodically help with fixing ports
security issues and documenting them in the FreeBSD VuXML
document. Committers who wish to help with this effort can
contact simon@ for details.</p>
<p>The following FreeBSD releases are supported by the FreeBSD
Security Team: FreeBSD 5.5, FreeBSD 6.1, and FreeBSD 6.2. The
respective End of Life dates of supported releases are listed on
the web site; it is expected that of the upcoming releases,
FreeBSD 6.3 will be supported for two years after release, while
FreeBSD 7.0 will be supported for one year after release.</p>

<p>The project consists in a rewriting of the lockmgr(9)
interface on a lighter basis, using atomic instructions and
direct usage of the sleepqueue interface. This should lead to a
faster primitive, a saner interface and an higher maintainability
of the code.</p>
<p>So far, 3 newly files called kern/kern_lockng.c,
sys/_lockmgrng.h and sys/lockmgrng.h have been created for the
new primitive and an initial implementation has been committed
into the perforce branch:
//depot/user/attilio/attilio_lockmgr/...</p>
<p>The implementation contains a good set of code intended to
replace old lockmgr. Actually it only misses the support for lock
draining that will be committed after an initial phase of testing
and the inclusion of a better wake-up algorithm (which will
simplify draining a lot and will improve performance on
wakeup).</p>

<p>My previous status reports contained a lot of code that
updated gvinum with the old vinum features.</p>
<p>This year gvinum has been significantly rewritten. Lukas Ertl
began rewriting the way gvinum is organized from using a multi
consumer/provider model, to use a single consumer and provider,
and having an event-system that first handles user-requests, and
then runs normal I/O operations (Much like other GEOM classes).
This makes the code easier to read, and perhaps there will be
less bugs :)</p>
<ol>
<li>setstate on plexes and volumes.</li>
<li>attach/detach command now works.</li>
<li>concat/stripe/mirror commands. The previous code conflicted
more than I expected with the new gvinum system, but it should
work now.</li>
<li>(Mounted) rebuilds possible.</li>
<li>(Mounted) sync possible.</li>
<li>Some refactoring of old code (Basically updating old code
to use the new event system, and add some abstractions where
possible)</li>
</ol>
<p>And of course, some time has gone to work out how things
should be done, and to fix other bugs. I hope some of you are
interested in trying this out (all the work has been in perforce
so far), a patch can be found in the URL section. . This is a bit
experimental, and although I've done much testing to hunt down
bugs, there are most probably bugs left.</p>
<p>I have other goals this summer as well. However, since some
parts of gvinum was rewritten, I might not be able to do all of
these, but growing is already working for the concatenated
volumes (and also mirrored). I'd also like to implement growing
for Raid5 arrays as well. Logging plexes would also be cool to
have, but this is not really needed, since we have g_journal.
Both these features will be addressed after I've made sure gvinum
does all old vinum does, and also perhaps better. As I might have
some extra time on my hands this summer, so I gladly accept
suggestions on what else I might fix or implement "while I'm at
it".</p>
</body>
<help>
<task>Stability, stability, stability. I want gvinum to work
really well. To accomplish that I have several test-machines I'm
going to do different tests on. I sort of have a little test-plan
in the working that I'll be using.</task>
<task>A gvinumadmin tool that would make gvinum easier to use for
unexperienced users. Perhaps integrate this into the installer.
This is now probably something I'll do at the end, when hopefully
everything works :) I might poke Ivan Voras a bit on this.</task>

take notes on where I need to document, so this is in
progress.</task>

<p>About 18 months ago, I started to remove the compatibility
macros that we had in the USB stack. These macros made it very
hard to read the code and to diagnose problems. They represented
a barrier to entry for people reading and understanding the
stack. In addition, many of them effectively hid bugs from all
but the most intensive investigations of the code.</p>
<p>I've removed almost all of the macros in the client drivers,
and all instances of the macros in the core FreeBSD USB stack.
This makes the drivers more readable, and a little more robust.
During this process, I fixed a lot of little bugs that people had
been tripping over, and some that people hadn't reported. I've
added a boatload of new vendor and product ids to the drivers
from user PRs as well as from OpenBSD/NetBSD drivers.</p>
<p>I finished up this work so that the FreeBSD USB stack would be
more maintainable during the RELENG_7 period of time. I plan on
MFCing most of the changes I've made into RELENG_6 after they
have been shaken out in current. There was only one API changes
in this work, so this is doable, and makes sharing drivers
between 6.x and 7.x much easier. At this stage, it is unclear how
long RELENG_6 will be around, so I'm hoping this will make USB
much better in 6.3 if that's the release people choose to
run.</p>
<p>I've shied away from many of the more complicated changes to
the stack. There's work being done outside of the tree by Hans
Petter Selasky (hps) to make these sorts of changes. There is
much in his stack that's ready to be merged, and I hope to
integrate from that work useful bits that can be merged without
disruption to improve the FreeBSD USB stack.</p>
<p>I'm also looking for other FreeBSD developers that can jump in
and help. Nearly all of the improvements I've done by spending a
few hours a week sorting through the PRs for extremely low
hanging fruit. There's plenty of room for others to be involved
as well in improving FreeBSD's USB stack, as well as chances for
us to import the now-useful bits from the evolving hps USB stack,
hopefully reducing the diffs between it and the present FreeBSD
USB stack. In addition, I'm looking for someone to do similar
device ID merges from DragonFlyBSD.</p>
<p>Finally, I've embarked on a mission to try to merge all the
BSD's usbdevs files. There's no reason to have separate ones.
I've started to modify usbdevs(1) to read the
src/sys/dev/usb/usbdevs file and report more verbose information
that way. A merged usbdevs would be larger, and take up more
memory in a USBVERBOSE kernel, so to mitigate that effect, I'm
making changes to usbdevs(1).</p>
</body>
<help>
<task>The biggest area of concern before the 7.0 release is to
get the updated device lists into the manual pages. This task is
too big for me to take on in addition to the work I'm doing in
cleaning up.</task>

'trivial' PRs that add IDs to the driver. In addition, we need

<p>A major update of the 802.11 wireless support was committed.
Changes include advanced station mode facilities such as
background scanning and roaming, and support for 802.11n devices.
In addition parts of the Atheros' SuperG protocol extensions were
added so that wireless clients that communicate with
Atheros-based access points can operate more effectively. The
changes to the infrastructure are also important because they
simplify future distribution of Virtual AP (VAP) support.</p>
<p>This work represents the effort of many people including Kip
Macy, Andrew Thompson, Sepherosa Ziehau, Max Laier, and Kevin Lo.
Getting these changes into the tree now ensures they will be
present for the lifetime of the 7.x branch.</p>
<p>The scanning and SuperG work were supported by Atheros. The
802.11n-related work was supported by Marvell.</p>

<title>FreeBSD and Wake On Lan</title>

<p>I have been working on making wake on lan (WOL) work with
FreeBSD. Contrary to popular believe OS support is required for
WOL to work properly. In particular network card drivers need to
configure network cards for WOL during system shutdown, else the
cards won't wake up. WOL is _not_ just a BIOS issue.</p>
<p>This is work in progress. Currently the following
cards/chipsets are supported:</p>
<ul>
<li>NatSemi DP83815 (if_sis)</li>
<li>Via Rhine (if_vr, only VT6102 and up chips support
WOL)</li>
<li>Nvidia nForce (if_nve,
<b>needs testing</b>
)</li>
<li>3Com Etherlink XL and Fast Etherlink XL (if_xl,
<b>needs testing</b>
, only 3c905B type adapters support WOL)</li>
</ul>
<p>I would be glad to get more feedback on my patch. I can add
support for more chipsets but I need testers for hardware I don't
have. I would appreciate access to data sheets for any NIC
chipsets that are supported by FreeBSD and have WOL support.</p>
<p>I would especially appreciate technical feedback on the patch,
preferably by a committer who is willing to nitpick the patch to
make it ready for inclusion in -CURRENT. I currently maintain the
patch against RELENG_6_2 for my own use but I would port it to
-CURRENT for inclusion.</p>

<p>Work is well under way to finish Kip Macy's FreeBSD/xen port,
and get it into a shape which is suitable for inclusion in
7.0.</p>
<p>Generally, the port is stable and performs quite well. The
major bottleneck is the inability to work with GCC 4.2, this is
the last major TODO before the work can be committed.</p>

<p>pf in HEAD (soon to be FreeBSD 7.0) has been updated to
OpenBSD 4.1 bringing in a couple of new features:</p>
<ul>
<li>ftp-proxy has been rewritten, and a tftp version,
tftp-proxy, has been added</li>
<li>pf(4) now supports Unicast Reverse Path Forwarding (uRPF)
checks for simplified ingress filtering</li>
<li>The pflog(4) interface is now clonable. pf(4) can log to
multiple pflog interfaces now, each rule can specify which
pflog interface to log to</li>
<li>pflogd(8) can now be told which pflog interface to work
with</li>
<li>pfctl(8) can now expire table entries</li>
<li>keep state is now the default for pf.conf(5) rules, as is
the flags S/SA option on TCP connections. no state and flags
any can be used to disable stateful filtering or TCP flags
checking</li>
<li>The pfctl(8) ruleset optimiser can be enabled in
pf.conf(5)</li>
<li>pf(4) anchors can now be loaded inline in the main
pf.conf(5) and can be printed recursively</li>
<li>Allow pf(4) rules inside anchors to have their counters
reset, and make counter read & reset an atomic
operation</li>
</ul>
<p>Some patches that went into OpenBSD after 4.1 and improve
performance significantly will be merged later.</p>
<p>Work to support pf and netgraph interaction is underway and
will be imported after 7.0. As all required ABI changes have been
made during the update, we will be able to MFC this work for 7.1
later on.</p>

<p>FreeBSD's static analysis scans have been updated with a
recent version of Coverity Prevent. Coverity is providing
additional advice on configuration of the analysis to maximize
the benefit from the tools.</p>
<p>At BSDCan2007, Coverity provided FreeBSD with a license for an
additional analysis tool called Extend, which allows writing
custom FreeBSD specific code checkers. David Maxwell presented
training material for interested FreeBSD developers. Some
applications of custom checkers have been considered, and more
results will be forthcoming as they are implemented and
tested.</p>
