<title>Introduction</title>
<p>This bi-monthly report covers development activities on the FreeBSD
Project for December 2001 and January 2002. A variety of
accomplishments have been made over the last couple of months,
including strong progress relating to the KSE project, which
brings Scheduler Activations to the FreeBSD kernel, as well
as less visible infrastructure projects such as improvements
to the mount interface, PAM integration work, and translation
efforts. Shortly following the deadline for this status
report, the BSD Conference and FreeBSD Developer Summit were
held, and will be covered in the next bi-monthly report at
the end of March. Plans are already under way for the USENIX
Annual Technical Conference in Monterey, CA, later this year,
and all and sundry are encouraged to attend to get further
insight in FreeBSD development.</p>

<p>I've been working to integrate recent improvements in the
NetBSD usb stack to FreeBSD -current. Both NetBSD and OpenBSD
currently share the same source, as FreeBSD did too at once point
before it diverged. The goal is to get back to that state, but
there are many improvements on both sides that need to be merged
before this is complete.</p>
<p>I'm currently looking for someone to help maintain usb in
-stable. Please let me know if you're interested.</p>

<p>Patches for cp(1), ls(1), and mv(1) to bring in
POSIX.1e-compliant Access Control List support have been updated
to patch against builds of -CURRENT. Other system utilities are
currently being evaluated for ACL support including install(1)
(patch available) and mtree(8). Work is in progress to verify the
native getfacl(1), setfacl(1), and other utilities build and work
correctly on other ACL-enabled systems (e.g. Linux w/ACL patches)
and to help verify POSIX-compliance of the continuing TrustedBSD
work along with other systems. Finally, experimental Perl and PHP
modules are available allowing limited access to native ACLs for
languages other than C.</p>

<p>The project is making progress. The goal is to design and
implement Host Controller Interface (HCI) and Link Layer Control
and Adaptation Protocol (L2CAP) layers using Netgraph framework.
More distant goal is to write support for Service Discovery
Protocol (SDP) and RFCOMM protocol (Serial port emulation over
Bluetooth link) . All information was obtained from Bluetooth
Specification Book v1.1.</p>
<p>Project status: In progress. 1) Design: mostly complete, there
are some minor issues to be resolved. 2) Implementation: Kernel -
HCI and L2CAP Netgraph nodes have been implemented; 3) User space
(API, library, utilities) - in progress. 4) Testing: In progress.
I do not have real Bluetooth hardware at this point, so i wrote
some tools that allow me to test the code. Some of them will be
used as foundation for future user space utilities.</p>
<p>Issues: 1) Bluetooth hardware; I do not have real Bluetooth
hardware, so if people can donate hardware/specs it would be
great. I promise to write all required drivers and make them
available. I also promise to return hardware/specs on first
request. 2) Project name; I would like to see the name that
reflects the following: it is a Bluetooth stack, implementation
is for FreeBSD and implementation is based on Netgraph
framework</p>

<p>This project is now finally underway, thanks to DARPA and NAI
getting a sponsorship lined up. The infrastructure code and data
structures are currently taking form inside a userland simulation
harness. Basic MBR and BSD methods have been written and device
attach/taste/dettach algorithms been implemented and
validated.</p>

<p>I've update OS of buildboxes to the latest FreeBSD 5-current
and 4-stable. Everything goes fine. From January 2002, I've
started a webzine, SNAPSHOTS Notes (only Japanese version is
available). SNAPSHOTs Notes pickups tips and information
especially for the people living with FreeBSD 5-current/4-stable.
Article or idea for SNAPSHOTs notes are always welcome (you don't
need to write in Japanese :-).</p>

<p>Robert Watson created the TrustedBSD audit perforce tree,
which is a branch from the TrustedBSD base tree, in order to
start pushing development efforts towards using a revision
control system. Andrew Reiter started to merge in some framework
related code for generation of audit records, enqueueing writes,
and handling data writing. There is a great deal of work to be
done with updates and discussion on the
trustedbsd-discuss@TrustedBSD.org mailing list.</p>

<p>The KSE project (an attempt to support scalable thread in
FreeBSD using kernel support), has reached What I call "milestone
3". At this milestone it is possible to run a multithreaded
program on a single CPU but with full concurrency of threads on
that CPU. In other words the kernel supports the fact that one
thread can block by allowing another thread to run in its place.
A test program that demonstrates this is available at the above
website.</p>
<p>Milestone 4 will be to allow threads from the same program to
run on multiple CPUs but may require more input from the SMPng
project. I am at the moment (Feb 6) getting ready to commit a
first set of changes for milestone 3, that have no real effect
but serve to drastically reduce the complexity of the remaining
diff so that others can read it more easily. After changes to
libkvm to support this diff have been added it should be possible
to run 'ps' and look at multiple threads in a treaded process. I
will be demonstrating KSE/M3 at BSDcon.</p>

<p>The Netgraph ATM package has been split into a number of
smaller packages: bsnmp is a general-purpose SNMP daemon with
support for loadable modules. Two modules come with it: one
implementing the standard network-interface and IP related parts
of MIB-2 and one for interfacing other modules to the NetGraph
sub-system. ngatmbase contains the drivers for the ATM hardware,
the ng_atm netgraph type and a few test tools. This package
allows one to use ATM PVCs. It should be possible, for example,
to do PPP over ATM with this package. Both bsnmp and ngatmbase
are available in version 1.0 under the link above. Two other
modules will be released in February: ngatmsig containing the
UNI-4.0 signalling stack as netgraph nodes and ngatmip containing
CLIP and LANE-2.0.</p>

<p>A significant amount of progress was made in December and
January, particularly in the area of utility conformance. Several
utilities were updated to conform to SUSv3, they include: at(1),
mailx(1), pwd(1), split(1), and uudecode(1). Several patches have
been submitted to increase conformance in other utilities, they
include: fold(1), patch(1), m4(1), nice(1), pr(1), renice(1),
wc(1), and xargs(1). These are in the process of being reviewed
and committed. Two new utilities have been written, specifically
pathchk(1) and tabs(1). These are also being reviewed and will be
committed shortly.</p>
<p>A patch which implements most of the requirements of scanf(3) is
being reviewed and is expected to be committed shortly. This will
allow us to MFC a number of new functions and headers.
Additionally, work has started on wide string and complex number
support.</p>

stable enough to be merge into the FreeBSD tree, you can get and

<p>The FreeBSD in Bulgarian project aims to bring a more
comfortable working environment to Bulgarian users of the FreeBSD
OS. This includes, but is not limited to, font, keymap and locale
support, translation of the FreeBSD documentation into Bulgarian,
local user groups and various forms of on-line help channels and
discussion forums to help Bulgarians adopt and use FreeBSD.</p>
<p>A guide for using FreeBSD with Bulgarian settings has been put
up on the project's website. The CVS repository will be made
public shortly, linked to on the URL's above.</p>
<p>An independent project for making FreeBSD easier to use by
Bulgarians has appeared, <a
href="http://www.FreeBSD-bg.org/">http://www.FreeBSD-bg.org/</a>.
It also hosts a mailing list for discussions of FreeBSD in
Bulgarian, <a href="mailto:stable@FreeBSD-bg.org">
stable@FreeBSD-bg.org</a>. For more information about the mailing
list, send an e-mail with "help" in the message body to

<p>The past two months have been an exciting time in the FreeBSD
Java Project with the signing of a license between the FreeBSD
Foundation and Sun allowing us access to updated JDK source code
and the Java Compatibility Kit (JCK). This license will also
allow the project to release a binary version of both the JDK and
JRE once JCK testing is complete. Work on this testing is under
way with the project hopeful of being able to make a binary
release in the not too distant future.</p>
<p>In lieu of the binary release which was hoped for with FreeBSD
4.5 the project will release an updated source patchset this
weekend. This patchset will feature further work on the FreeBSD
"native" threads subsystem from Bill Huey. Also, thanks to hard
work by Joe Kelsey and Fuyuhiko Maruyama, the patchset will for
the first time feature a working Java browser plugin!</p>

<p>Extending camcontrol's page definition file format to include
both modepage and logpage definitions; adding support to
camcontrol to query and reset log page parameters. Consideration
is being made to possibly include support for diagnostic and
vital product data pages, but that is outside the current project
scope. New page definition file format includes capability to
conditionally include page definitions based on SCSI INQUIRY
results allowing vendor-specific pages to be described also.
Approximately 90% complete.</p>

<p>OpenPAM, a new library intended to replace Linux-PAM in
FreeBSD, has been written and is undergoing integration testing.
It is available for download from the URL listed above.</p>
<p>In addition to this, a couple of new modules have been written
(pam_lastlog(8), pam_login_access(8)), and the pam_unix(8) module
has been extended to perform most of the tasks normally performed
by login(1), which is now fully PAMified.</p>
<p>The PAM FDP article has been put on hold until OpenPAM
replaces Linux-PAM in CVS, to avoid wasting effort on soon-to-be
obsolete documentation.</p>

<p>Substantial progress has been made towards a working MAC
implementation. The focus over the last two months has been
moving from a hard-coded series of MAC policies to a more
flexible implementation. A pluggable policy framework has been
created (and is still under development), supporting Biba, MLS,
TE, a "BSD Extended" model, and a sample mac_none module. Some
modules must be compiled in or loaded prior to boot; others may
be introduced at run-time. Support for networking has improved,
with improved handling of IP fragmentation in IPv4, support for
various pseudo-interfaces such as if_tun and if_tap, improved
integration into userland, NFS-related fixes, moving the VFS
enforcement out of individual filesystems, support for a
'multilevel' mount flag, support for explicit labeling in procfs
and devfs, addition of an 'extattrctl lsattr' argument to list
EAs on a filesystem, support for label ranges in the Biba and MAC
policies, and much more.</p>
<p>Targets for the next two months include more universal
enforcement of VFS-related calls, improved support for
alternative ABIs, improved flexibility of in-kernel subject and
object labels, support for IPv6 and IPsec, and improved support
for NFS serving.</p>
<p>Development continues in the FreeBSD Perforce repository,
which may be accessed using cvsup.</p>

<p>Now that the patch has been mailed to the
freebsd-arch@FreeBSD.org mailing list, and that there were no
objections, the commit will happen soon. Poul is currently
testing it in his own tree. After it has been committed, it will
be time to modify the filesystems in the tree to use VFS_NMOUNT
instead of VFS_MOUNT. Mount(8) will also need some modifications.
Some new manpages -- nmount(2) and kernel_vmount(9) -- are being
created in the meantime.</p>

<p>Alfred Perlstein committed file descriptor locking code
which was definitely a good push towards trying to lock down
some important pieces of global data. Peter Wemm has made
progress on pmap cleanups for x86 SMP TLB shootdowns. Matt
Dillon and John Baldwin have made progress on getting patches
done for moving accesses to ucred's out from under Giant's
protection. John Baldwin has also made some commits in order
to get the alpha port's SMP working. Matt Dillon has plans
for hunting down fileops locking issues in order to continue
his previous Giant pushdown work.</p>
