October-December 2003 Status Report
Introduction:
The FreeBSD status reports are back again with the 2003 year-end edition.
Many new projects are starting up and gaining momentum, including XFS,
MIPS, PowerPC, and networking locking and mutlithreading. The end of 2003
also saw the release of FreeBSD 4.9, the first stable release to have
greater than 4GB support for the ia32 platform. Work on FreeBSD 5.2 also
finished up and was released early in January of 2004. Many thanks to all
of the people who worked so hard on these releases and made them happen.
This is the largest status report ever, so read and enjoy!

Bluetooth stack for FreeBSD (Netgraph implementation)
Contact: Maksim Yevmenkin < m_evmenkin@yahoo.com >
Not much to report. Bluetooth code was integrated into the FreeBSD source
tree. Bluetooth kernel modules appear to be stable. I have received few
success stories from the users.
During last few months the efforts were to make Bluetooth code more user
friendly. Bluetooth Service Discovery Procotol daemon sdpd was
reimplemented under BSD-style license and committed. The next step is to
integrate existing Bluetooth utilities with SDP.
Thanks to Matt Peterson matt at peterson dot org> I now have Bluetooth
keyboard and mouse for development. I'm currently working on Bluetooth
HID
profile implementation.
Dave Sainty (dave at dtsp dot co dot nz) from NetBSD project offered his
help in porting Bluetooth stack to NetBSD.

ACPI
URL: http://www.root.org/~nate/freebsd/
URL: http://http://home.jp.freebsd.org/mail-list/acpi-jp/
Contact: Nate Lawson <njl@FreeBSD.org>
The updated acpi_cpu driver was committed in November. Work is ongoing to
finish support for _CST re-evaluation, which makes it possible for laptops
based on processors like the Centrino to use varying CPU idle states when
on or off AC power. 5.2-RELEASE also went out with support for _CID
packages, which fixed mouse probing for Compaq users. Control of CPU idle
states and throttling can now be done through rc.conf(5) settings for the
/etc/power_profile script, which switches between performance/economy
levels when the AC status changes.
One huge task underway is the cpufreq project, a framework for detecting
and controlling various frequency/voltage technologies (SpeedStep,
LongRun, ACPI Performance states, etc.) The ACPI performance states driver
is working and the framework is being implemented. It requires newbus
attachments for CPUs so some ground work needs to go in before the driver
can be committed.
ACPI-CA was updated to 20031203 in early December and with a few patches
is reasonably stable. An ACPI debugging how-to has been written and is
being DocBooked by trhodes@. Ongoing work on fixing interrupt storms due
to various ways of setting up the SCI is being done by jhb@.
I'd like to welcome Philip Paeps (philip@) to the FreeBSD team. Philip
has
written an ACPI ASUS driver that will be committed soon and has been very
helpful on the mailing lists. We've also had a lot of help from jhb@,
marcel@, imp@, and peter@. We're hoping to see the return of takawata@
and
iwasaki@, who have been very helpful in the past. If any developers are
interested in assisting with ACPI, please see the ACPI TODO and send us an
email.
----------------------------------------------------------------------
AGP 3.0 Support
Contact: John Baldwin <jhb@FreeBSD.org>
Simple support AGP 3.0 including support for AGP 8x mode was added. The
support is simple in that it still assumes only one master and one target.
The main gain is the ability to use AGP 8x with drm modules that support
it.
----------------------------------------------------------------------
Binary security updates for FreeBSD
URL: http://www.daemonology.net/freebsd-update/
Contact: Colin Percival <cperciva@daemonology.net>
Thanks to recent donations, I am now building binary security updates for
FreeBSD {4.7, 4.8, 4.9, 5.0, 5.1, 5.2}-RELEASE. (Note that FreeBSD 4.7 and
5.0 are no longer officially supported; any advisories which are not
reflected in the CVS tree will likewise not result in binary updates.)
The current version (1.5) of FreeBSD Update will warn about locally
modified files and will, by default, leave them untouched; if a
"distribution branch", (i.e. crypto, nocrypto, krb4, or krb5) is
specified, FreeBSD Update can be forced to "update" files which
have been
compiled locally.
The only major issue remaining with FreeBSD Update is the
single-point-of-failure of the update building process; I would like to
resolve this in the future by having several machines cross-verify and
cross-sign, but this will require a significant investment of time, and
will probably have to wait until I've finished writing my DPhil thesis.
----------------------------------------------------------------------
Compile FreeBSD with Intels C compiler (icc)
URL: http://www.Leidinger.net/FreeBSD/
Contact: Alexander Leidinger <netchild@FreeBSD.org>
The FreeBSD kernel now builds and runs fine with icc v7 (only GENERIC and
a custom kernel tested so far). A review on arch@ revealed no major
concerns and some src committers are willing to commit the patches. As icc
v8 is out and defines __GNUC__ I want to rework the patches before they
get committed so an icc v8 compiled kernel DTRT too.
A complete build of the ports collection (as of start of December)
finished and is under review to determine the reason of build failures.
Current icc stats:
* 1108 failed builds (excluding build failures because of failed
dependencies)
* 3535 successfully build packages (~ 1.7 GB)
A parallel build with gcc on the same snapshot of the ports collection
has:
* 520 failed builds (excluding build failures because of failed
dependencies) and
* 7261 successfully build packages (~ 4.8 GB).
The above mentioned build of the ports collection was run on a P4 with a
icc compiled kernel (optimized for a P4). No kernel panics or other
strange behavior was noticed. The ports collection was build with a
CPUTYPE of p4 and CFLAGS set to "-Os -pipe -mfpmath=sse -msse2" in
the gcc
and "-O2" in the icc case. No package is tested for correct
run-time
behavior so far.
----------------------------------------------------------------------
Donations Team
URL: http://www.freebsd.org/donations/
Contact: Michael Lucas <donations@FreeBSD.org>
2003 was quite successful for the Donations team. We shepherded over 200
items from donors into the hands of developers. Some high points include:
a small cluster for the security team, assorted laptop hardware for our
cardbus work, and documentation for our standards group. In the main
FreeBSD.org cluster we were able to replace 8 DEC Miata machines with 6
Alpha DS10s (21264). Every committer doing SMP work now has
multi-processor testing hardware.
We have smoothed out the tax deduction process with the FreeBSD
Foundation, and can ship donated items directly to the recipients instead
of tying up Foundation time handling shipping.
Current team membership is: Michael Lucas, David O'Brien, and Tom Rhodes.
Wilko Bulte has replaced Robert Watson as the Core Team representative.

DVB-ASI Support
URL: http://proxy.6wind.com/~jardin/dvb/
URL: http://www.computermodules.com/broadcast/broadcast-dvb.shtml
URL: http://www.dvb.org/
Contact: Vincent Jardin <Vincent.Jardin@6wind.com>
DVB ASI stands for Digital Video Broadcast - Asynchronous Serial
Interface. It is the standard defined to send and receive DVB stream from
Satellite (DVB-S), Terrestrial link (DVB-T), and TV Cable (DVB-C). This
standard was developed in Europe to transport 188-byte MPEG cells and
204-byte MPEG cells. However it can be used to carry IP over DVB too.
The FreeBSD driver uses the newbus amd the bus-dma API. It means that it
could be easily ported to all the BSD flavors (NetBSD, OpenBSD).
It uses the same API than the Linux DVB ASI support from ComputerModules
that is based on the following devices:
* /dev/asitxN for the transmit stream (only open, write, select, close
and ioctl are supported).
* /dev/asirxN for the receive stream (only open, read, select, close and
ioctl are supported).
It means that software such as Videolan that support DVB-ASI broadcasting
could be supported by this driver.
Special thanks to Tom Thorsteinson from Computer Modules who helped 6WIND
to port their driver. It is used by 6WIND in order to provide IPv4, IPv6,
Ethernet and our network services over DVB.

----------------------------------------------------------------------
FreeBSD MIDI
Contact: Mathew Kanner <matk@FreeBSD.org>
This project aims to update the current MIDI implementation. We are
currently looking at removing the current code sometime in February and
importing the new version soon after. I'm currently working on a
kernel/timidiy bridge for those without external hardware.
----------------------------------------------------------------------
FreeBSD ports monitoring system
URL: http://lonesome.dyndns.org:4802/bento/errorlogs/index.html
Contact: Mark Linimon <linimon_at_lonesome_dot_com>
Enhancements continue to be made to the system. Several, including
improvements to the PR classification algorithm, the ability to more
correctly guess when a PR has been updated, and better handling of errors
in both port Makefiles and the bento builds, are invisible to end-users.
However, the addition of a "repocopy" classification is notable, as
is the
allowing the wildcard search in "overview of one port" (thanks to
edwin@
for the shove in that direction.) Additionally, logic has been added to
identify the proposed category/portname of new ports, with the goal being
to quickly identify possible duplications of effort. (Some SQL performance
was sacrificed to this goal, leading to some pages to load more slowly;
this needs to be fixed.)
The other work has been on an email back-end to allow the occasional
sending of email to maintainers. Two functions are currently available:
"remind maintainers of their ports that are marked BROKEN", and
"remind
maintainers of PRs that they may not have seen." A recent run of the
former got generally good response, especially as changing some cases of
BROKEN to IGNORE (PR ports/61090) had removed almost all the annoying
false positives. However, work remains to try to find out why a few
allegedly broken ports only fail in certain environments (including the
bento cluster).
The next plan is to use the proposed DEPRECATED Makevar (see ports/59362)
to create a new report to allow querying of "ports currently slated to
be
removed". This report could also be posted to ports@ periodically with
minimal work. The author believes that doing this would allow the port
deprecation process to be much more visible to the general FreeBSD user
community.
----------------------------------------------------------------------
FreeBSD/MIPS Status Report
URL: http://www.FreeBSD.org/projects/mips/
Contact: Juli Mallett <jmallett@FreeBSD.org>
TLB support code and PMAP have come along nicely. GCC and related have
been kept up to date with the main tree. An evaluation board from Broadcom
was donated and initial work on that platform has been occurring. Much old
and obsolete code brought from NetBSD for bootstrapping the effort has
been cleaned up. The system has been seen to get to the point of trying to
initialize filesystems, but there are still bugs even before that
milestone.
----------------------------------------------------------------------
FreeBSD/powerpc on PPCBug-based embedded boards
URL: http://www.example.com/project/url/here
URL: http://www.example.net/another/url
Contact: Rafal Jaworowski <rafal.jaworowski@motorola.com>
The direct objective is to make FreeBSD/powerpc work on Motorola MCP750
and similar (single board computer that is compliant with Compact PCI
standard) Based on this work it would be easy to bring it to other
embedded systems.
1. loader(8) It is based on the existing loader for FreeBSD/powerpc port
but binding to OpenFirmware was removed and replaced with PPCBug firmware
binding. It only supports netbooting for the moment, so disk (compact
flash) support needs to be done one day. The loader is the only piece that
relies onPPCBug system calls - once the kernel starts it doesn't need
firmware support any longer.
2. kernel It is now divorced from OpenFirmware dependencies; most of the
groundwork finished includes: nexus stuff is sorted out (resources
management is ok except interrupts assignment); host to PCI bridge low
level routines are finished so configuration of and access to PCI devices
works; the only important thing missing is the IRQ management (Raven MPIC
part is done, but the board has the second PIC, 8259-compatible that needs
to be set up, but here the existing code from x86 arch will be adopted)
Once the IRQ management is cleared out, most of the devices on board would
work straight away since they are pretty standard chips with drivers
already implemented in the tree (e.g. if_de).
At the moment work is on hold (don't have physical access to the device)
but will resume when I'm back home (late Feb)
----------------------------------------------------------------------
jpman project
URL: http://www.jp.FreeBSD.org/man-jp/
Contact: Kazuo Horikawa <horikawa@FreeBSD.org>
We have been updating existing Japanese translations of manual pages to
meet the 5.2-RELEASE schedule. Also, 22 new translations were complete
during this period.
----------------------------------------------------------------------
Kernel Tunables Documentation Project
URL: http://www.freebsd.org/cgi/query-pr.cgi?pr=docs/44034
Contact: Tom Rhodes <trhodes@FreeBSD.org>
FreeBSD has well over a few hundred tunables without documentation. This
project aims at designing an automated process to rip all available
tunables and generate a manual page based on the selected kernel options.
The ideal implementation, however; would gather tunables from the LINT
kernels as well. This would provide a default manual page for all
supported architectures. A simple tool has been forged from the various
off-list and on-list discussions and is waiting review from the -doc team.
Anyone interesting in reviewing my current work is requested to get in
contact with me.
----------------------------------------------------------------------
kgi4BSD Status Report
URL: http://www.freebsd.org/~nsouch/kgi4BSD
URL: http://www.kgi-project.org
Contact: Nicholas Souchu <nsouch@FreeBSD.org>
Most of the console blocks are in place with nice results (see screenshots
on the site). Boot console and virtual terminals are working with 8bit
rendering and perfect integration of true graphic drivers in the kernel.
Now it is time to bring it to end user and a precompiled R5.2 GENERIC
kernel is available for this (see the site news). In parallel, after
providing a last tarball/patch for R5.2, everything will move to Perforce.
As always, volunteers are welcome. The task is huge but very exciting.
----------------------------------------------------------------------
KSE
Contact: Daniel Eischen <deischen@FreeBSD.org>
The libkse library will shortly be renamed to libpthread and be made the
default thread library. This includes making the GCC -pthread option link
to -lpthread instead of libc_r and changing PTHREAD_LIBS to -lpthread.
David Xu has been working on GDB support and has it working with the GDB
currently in our tree. The next step is to make a libpthread_db and get it
working with GDB 6.0 which marcel has imported into the perforce tree.
----------------------------------------------------------------------
libarchive, bsdtar
URL: http://people.freebsd.org/~kientzle/libarchive/
Contact: Tim Kientzle <kientzle@FreeBSD.org>
The libarchive library, which reads and writes tar and cpio archives, is
about ready to commit to the tree. The bsdtar program, built on
libarchive, is also nearing completion and should soon be a worthwhile
successor to our aging GNU tar. I plan a gradual transition during which
"bsdtar" and "gtar" will coexist in the tree.
Oddly enough, libarchive and bsdtar are the first fruits of a project to
completely rewrite the pkg tools. I've started architecting a libpkg
library for handling routine package management and have a prototype
pkg_add that is three times faster than the current version.
----------------------------------------------------------------------
Network interface naming changes
Contact: Brooks Davis <brooks@FreeBSD.org>
At the end of October, the if_name and if_unit members of struct ifnet
were replaced with if_xname from NetBSD and if_dname and if_dunit. These
represent the name of the interface and the driver name and instance of
the interface respectively. Other then breaking IPFilter for a few weeks
due to the userland being on the vendor branch, this change went quite
well. A few ports needed minor changes, but otherwise nothing changed from
the user perspective.
The purpose of this change was the lay the groundwork for support for
network interface renaming and to allow the implementation of more
interesting pseudo interface cloning support. An example of interesting
cloning support would be using "ifconfig fxp0.20 create" to create
and
configure a vlan interface on fxp0 that handled frames marked with the tag
20. Interface renaming is being worked on in Perforce at the moment with a
working version expected for review soon. Support for enhanced device
cloning is still in the planing stage.
----------------------------------------------------------------------
Network Subsystem Locking and Performance
Contact: Sam Leffler <sam@FreeBSD.org>
The purpose of this project is to improve performance of the network
subsystem. A major part of this work is to complete the locking of the
networking subsystem so that it no longer depends on the "Giant
lock" for
proper operation. Removing the use of Giant will improve performance and
permit multiple instances of the network stack to operate concurrently on
multiprocessor systems.
Locking of the network subsystem is largely complete. Network drivers,
middleware layers (e.g. ipfw, dummynet, bridge, etc.), the routing tables,
IPv4. NFS, and sockets are locked and operating without the use of Giant.
Much of this work was included in the 5.2 release, but not enabled by
default. The remaining work (mostly locking of the socket layer) will be
committed to CVS as soon as we can resolve how to handle "legacy
protocols" (i.e. those protocols that are not locked). The code can be
obtained now from the Perforce database. A variety of test and production
systems have been running this code for several months without any obvious
issues.
Performance analysis and tuning is ongoing. Initial results indicate SMP
performance is already better than 4.x systems but UP performance is still
lagging (though improved over -current). The removal of Giant from the
network subsystem has reduced contention on Giant and highlighted
performance bottlenecks in other parts of the system.
This work was supported by the FreeBSD Foundation.
----------------------------------------------------------------------
Porting OpenBSD's pf
URL: http://pf4freebsd.love2party.net
URL: http://www.benzedrine.cx/pf.html
URL: http://openbsd.org/faq/pf/index.html
Contact: Max Laier <max@love2party.net>
Contact: Pyun YongHyeon <yongari@kt-is.co.kr>
Much work has been invested into getting release 2.00 stable. It provides
the complete OpenBSD 3.4 function set, as well as fine grained locking to
work with a giant free network stack.
pf provides: IPv6 filtering and normalization, "syn-proxy" to
protect
(web)server against SYN-floods, passive OS detection, fast and modular
address tables, source/policy routing, stateful filter and normalization
engine, structured rulesets via anchors and many many more. Especially in
connection with ALTQ, pf can help to harden against various flood attacks
and improve user experience.
New features from OpenBSD-Current like: state synchronization over wire
and enhanced support for cloned interfaces require patches to the kernel.
We are trying to resolve this issue and start OpenBSD-Current tracking
again as soon as possible.
----------------------------------------------------------------------
Publications Page Update
URL: http://www.daemon.li/freebsd/
Contact: Josef El-Rayes <josef@daemon.li>
I did a xml/xslt conversion of the html files to make maintaining of the
page more comfortable. I removed the cdsets, which might be kept in CVS or
some kind of archive for historical reasons. The books got an update, and
were categorized in respect to the language they are written in. As soon
as I get my access on the cvs repository I will commit the updates. People
are encouraged to add local FreeBSD books, I missed, especially in the
asian area. Feel free to send me links to books to add.
----------------------------------------------------------------------
SGI XFS port for FreeBSD
Contact: Alexander Kabaev <kan@FreeBSD.org>
Contact: Russell Cattelan <cattelan@thebarn.com>
A project was started to revive a stalled effort to port SGI XFS
journaling filesystem to FreeBSD. The project is based on Linux
development sources from SGI and is currently being kept in a private
Perforce repository. The work is progressing slowly due to lack of free
time. At the moment we have XFS kernel module which is capable of mounting
XFS filesystems read-only, with a panic or two happening infrequently,
that need to be isolated and fixed. Semi-working metadata updates with
full transaction support are there too, but will probably have to be
rewritten to minimize the amount of custom kernel changes required.
We seek volunteers to help with userland part of the port. Namely,
existing xfsprogs port needs to be cleaned up, incompletely ported
utilities brought into a working shape. xfs_dump/xfs_restore and as much
from xfstests suite as possible need to be ported too. We do not need
testers for now, so please to not ask for module sources just yet.
----------------------------------------------------------------------
SMPng Status Report
URL: http://www.FreeBSD.org/smp/
Contact: John Baldwin <jhb@FreeBSD.org>
Contact: <smp@FreeBSD.org>
Work is progressing on SMPng on several different fronts. Sam Leffler and
several other folks have been working on locking the network stack as
mentioned elsewhere in this update. Several infrastructure improvements
have been made in the past few months as well.
The low-level interrupt code for the i386 architecture has been redesigned
to allow for a runtime selection between different types of interrupt
controllers. This work allows the Advanced Programmable Interrupt
Controllers (APICs) to be used instead of the AT 8259A PIC without having
to compile a separate kernel to do so. It also allows the APIC to be used
in a UP kernel as well as on a UP box. Together, all these changes allow
an SMP kernel to work on a UP box and thus allowed SMP to be enabled in
GENERIC as it already is on all of the other supported architectures. This
work also reworked the APIC support to correctly route PCI interrupts when
using an APIC to service device interrupts. This work was also used to add
SMP support to the amd64 port.
A turnstile implementation was committed that implemented a queue of
threads blocked on a resource along with priority inheritance of blocked
threads to the owner of the resource. Turnstiles were then used to replace
the thread queue built into each mutex object which shrunk the size of
each mutex as well as reduced the use of the sched_lock spin mutex.

Contact: Andrey Zakhvatov <andy@FreeBSD.org>
The FreeBSD Russian Documentation Project aims to provide FreeBSD
Documentation translated to Russian. Already done: FAQ, Porters Handbook,
WWW (partially synched with English version), some articles.
We working at Handbook (and more docs) translation and synchronization
with English versions and need more translators (or financial aid to
continue our work. If you can help, please, contact us at

TrustedBSD "Security-Enhanced BSD" -- FLASK/TE Port
URL: http://www.TrustedBSD.org/sebsd.html
Contact: Robert Watson <rwatson@FreeBSD.org>
Contact: TrustedBSD Discussion Mailing List
<trustedbsd-discuss@TrustedBSD.org>
TrustedBSD "Security-Enhanced BSD" (SEBSD) is a port of NSA's
SELinux
FLASK security architecture, Type Enforcement (TE) policy engine and
language, and sample policy to FreeBSD using the TrustedBSD MAC Framework.
SEBSD is available as a loadable policy module for the MAC Framework,
along with a set of userspace extensions support security-extended
labeling calls. In most cases, existing MAC Framework functions provide
the necessary abstractions for SEBSD to plug in without SEBSD-specific
changes, but some extensions to the MAC Framework have been required;
these changes are developed in the SEBSD development branch, then merged
to the MAC branch as they mature, and then to the FreeBSD development
tree.
Unlike other MAC Framework policy modules, the SEBSD module falls under
the GPL, as it is derived from NSA's implementation. However, the
eventual
goal is to support plugging SEBSD into a base FreeBSD install without any
modifications to FreeBSD itself.
TrustedBSD SEBSD development branch in Perforce integrated to 5.2-RELEASE.
Other changes in the MAC branch, including restructuring of MAC Framework
files also integrated, and a move to zone allocation for labels. See the
TrustedBSD MAC Framework report for more detail on these and other MAC
changes that also affect the SEBSD work.
FreeBSD PTY code modified so that the MAC Framework and SEBSD module can
create pty's with the label of the process trying to access them.
Improves
compatibility with the SELinux sample policy. (Not yet merged)
SEBSD now loads its initial policy in the boot loader rather than using a
dummy policy until the root file system is mounted, and then loading it
using VFS operations. This avoids initial labeling and access control
conditions during the boot.
security_load_policy() now passes a memory buffer and length to the
kernel, permitting the policy reload mechanisms to be shared between the
early boot load and late reloads. The kernel SEBSD code now no longer
needs to perform direct file I/O relating to reading the policy.
checkpolicy now mmap's the policy before making the system call.
SEBSD now enforces protections on System V IPC objects and methods. Shared
memory, semaphores, and message queues are labeled, and most operations
are controlled. The sample policy has been updated.
The TrustedBSD MAC Framework now controls mount, umount, and remount
operations. A new MAC system call, mac_get_fs() can be used to query the
mountpoint label. lmount() system call allows a mount label to be
explicitly specified at mount time. The SEBSD policy module has been
updated to reflect this functionality, and sample TE policy has been
updated. (Not yet merged)
SEBSD now enforces protections on POSIX semaphores; the sample policy has
been updated to demonstrate how to label and control sempahores. This
includes sample rules for PostgreSQL.
The SEBSD sample policy, policy syntax, and policy tools have been updated
to the SELinux code drop from August. Bmake these pieces so we don't need
gmake.
Provide file ioctl() MAC Framework entry point and SEBSD implementation.
A large number of sample policy tweaks and fixes. The policy has been
updated to permit cron to operate properly. It has been updated for
FreeBSD 5.2 changes, including dynamically linked root. Teach the sample
policy about FreeBSD's sendmail wrapper.
Adapt sysinstall and install process for SEBSD pieces. Teach sysinstall,
newfs, et al, about multilabel file systems, install SEBSD sample policy
pieces, build policy. Automatically load the SEBSD module on first boot
after install.
Allow "ls -Z" to print out labels without long format.

TrustedBSD Access Control Lists (ACLs)
URL: http://www.trustedbsd.org/components.html#acls
Contact: Robert Watson <rwatson@FreeBSD.org>
Contact: TrustedBSD Discussion Mailing List
<trustedbsd-discuss@TrustedBSD.org>
TrustedBSD Access Control Lists (ACLs) provide extended discretionary
access control support for the UFS and UFS2 file systems on FreeBSD. They
implement POSIX.1e ACLs with some extensions, and meet the Common Criteria
CAPP requirements. Most ACL-related work is complete, with remaining tasks
associated with userspace integration, third party applications, and
compatibility
Prototyped Solaris/Linux semantics for combining ACLs and the umask: if an
default ACL mask is defined, substitute that mask for the umask,
permitting ACLs to override umasks. (Not merged)

<trustedbsd-audit@TrustedBSD.org>
The TrustedBSD Project is producing an implementation of CAPP compliant
Audit support for use with FreeBSD. Little progress was made on this
implementation between October and December other than an update to the
existing development tree. However, in January, work began on porting the
Darwin Audit implementation to FreeBSD. Details on this work will appear
in the next report; more information is available on the TrustedBSD audit
discussion list. Perforce messages may be seen on the trustedbsd-cvs
mailing list.

The TrustedBSD Project is implementing many new features for the FreeBSD
Project. It also provides documentation for users, administrators, and
developers.
mac_support.4 added -- documents TrustedBSD MAC Framework feature
compatibility. See also the MAC Framework report.
FreeBSD security architecture updated and corrections/additions made.
A variety of documentation updates relating to API changes, including the
socket-related API changes in libc/mac(3).

Contact: Robert Watson <rwatson@FreeBSD.org>
Contact: TrustedBSD Discussion Mailing List
<trustedbsd-discuss@TrustedBSD.org>
The TrustedBSD Mandatory Access Control (MAC) Framework permits the
FreeBSD kernel and userspace access control policies to be adapted at
compile-time, boot-time, or run-time. The MAC Framework provides common
infrastructure components, such as policy-agnostic labeling, making it
possible to easily development and distribute new access control policy
modules. Sample modules include Biba, MLS, and Type Enforcement, as well
as a variety of system hardening polices.
TrustedBSD MAC development branch in Perforce integrated to 5.2-RELEASE.
The TrustedBSD MAC Framework now enforces protections on System V IPC
objects and methods. Shared memory, semaphores, and message queues are
labeled, and most operations are controlled. The Biba, MLS, Test, and Stub
policies have been updated for System V IPC. (Not yet merged)
The TrustedBSD MAC Framework now enforces protections on POSIX semaphore
objects and methods. The Biba, MLS, Test, and Stub policies have been
updated. (Not yet merged)
The TrustedBSD MAC Framework's central kernel implementation previously
existed in one large file, src/sys/kern/kern_mac.c. It is now broken out
into a series of by-service files in src/sys/security/mac.
src/sys/security/mac/mac_internal.h specifies APIs, structures, and
variables used internally across the different parts of the framework.
System calls and registration still occur in kern_mac.c. This permits more
easy maintenance of locally added object types. (Merged)
Break out mac_policy_list into two different lists, one to hold
"static"
policy modules -- ones loaded prior to kernel initialization, and that may
not be loaded, and one for "dynamic" policy modules -- that are
either
loaded later in boot, or may be unloaded. Perform less synchronization
when using static modules only, reducing overhead for entering the
framework when not using dynamic modules. (Merged)
Introduced a kernel option, MAC_STATIC, which permits only statically
registered policy modules to be loaded at boot or compiled into the
kernel. When running with MAC_STATIC, no internal synchronization is
required in the MAC Framework, lowering the cost of MAC Framework entry
points. (Not yet merged)
Make mac.h userland API definition C++-happy. (Merged)
Created mac_support.4, a declaration of what kernel and userspace features
are (and aren't) supported with MAC. (Not yet merged)
Stale SEBSD module deleted from MAC branch; SEBSD module will solely be
developed in the SEBSD branch from now on. See the TrustedBSD SEBSD report
for more detail.
Use only pointers to 'struct label' in various kernel objects outside
the
MAC Framework, and use a zone allocator to allocate label storage. This
permits label structures to have their size changed more easily without
changing the normal kernel ABI. This also lowers the non-MAC memory
overhead for base kernel structures. This also simplifies handling and
storage of labels in some of the edge cases where labels are exposed
outside of the Framework, such as in execve(). Include files outside of
the Framework are substantially simplified and now frequently no longer
require _label.h. (Merged)
Giant pushed down into the MAC Framework in a number of MAC related system
calls, as it is not required for almost all of the MAC Framework. The
exceptions are areas where the Framework interacts with pieces of the
kernel still covered by MAC and relies on Giant to protect label storage
in those structures. However, even in those cases, we can push Giant in
quite a bit past label internalization/externalization/ storage
allocation/deallocation. This substantially simplifies file
descriptor-based MAC label system calls. (Merged)
Remove unneeded mpo_destroy methods for Biba, LOMAC, and MLS since they
cannot be unloaded. (Merged)
Biba and MLS now use UMA zones for label allocation, which improves
storage efficiency and enhances performance. (Merged)
Bug fix for mac_prepare_type() to better support arbitrary object label
definitions in /etc/mac.conf. (Merged)
Labels added to 'struct inpcb', which represents TCP and UDP
connections
at the network layer. These labels cache socket labels at the application
layer so that the labels may be accessed without application layer socket
locks. When a label is changed on the socket, it is pushed down to the
network layer through additional entry points. Biba, MLS policies updated
to reflect this change. (Merged)
SO_PEERLABEL socket option fixed so that peer socket labels may be
retrieved. (Merged)
mac_get_fd() learns to retrieve local socket labels, providing a simpler
API than SO_LABEL with getsockopt(). mac_set_fd() learns about local
socket labels, providing a simpler API than SO_LABEL with setsockopt().
This also improves the ABI by not embedding a struct label in the socket
option arguments, instead using the copyin/copyout routine for labels used
for other object types. (Merged)
Some function names simplified relating to socket options. (Merged)
Library call mac_get_peer() implemented in terms of getsockopt() with
SO_PEERLABEL to improve API/ABI for networked applications that speak MAC.
(Merged)
mac_create_cred() renamed to mac_cred_copy(), similar to other label
copying methods, allowing policies to implement all the label copying
method with a single function, if desired. This also provides a better
semantic match for the crdup() behavior. (Merged)
Support "id -M", similar to Trusted IRIX. (Not yet merged)
TCP now uses the inpcb label when responding in timed wait, avoiding
reaching up to the socket layer for label information in otherwise
network-centric code.
Numerous bug fixes, including assertion fixes in the MAC test policy
relating to execution and relabeling. (Merged)

Wireless Networking Support
Contact: Sam Leffler <sam@FreeBSD.org>
Work to merge the NetBSD and MADWIFI code bases is almost complete. This
brings in new features and improves sharing which will enable future
development. Support was added for 802.1x client authentication (using the
open1x xsupplicant program) and for shared key authentication (both client
and AP) which improves interopability with systems like OS X. The awi
driver was updated to use the common 802.11 layer and the Atheros driver
received extensive work to support hardware multi-rate retry. Kismet now
works with the device-independent radiotap capture format. All of this
work is still in Perforce but should be committed to CVS soon.
Work has begun on full 802.1x and WPA support.
