OpenAFS Newsletter, Issue 6, October 2009
Welcome to the sixth issue of the OpenAFS newsletter. This newsletter
summarizes what is happening in the OpenAFS community.
As always, volunteers, patches, bug reports, or any other type of help
is greatly appreciated.
Feedback on this newsletter is welcome. The goal is to summarize the
various development efforts and news of OpenAFS for the community.
Please let Jason Edgecombe <firstname.lastname@example.org> know what you would
like to see out of this newsletter. Any news about AFS-related projects
is welcome and may be submitted to Jason for inclusion in the next
The current and past issues of this newsletter are available at
General OpenAFS Progress
There were three OpenAFS 1.5.x releases since the last newsletter.
OpenAFS 1.5.65 was released on October 6, 2009. Highlights of this
release include several important bug fixes. All of the existing
compile-time warnings have been silenced, but they may be re-enabled
with a ./configure option. This was done to help prevent new warnings
from creeping into the code. The configure option can be used for those
developers trying to clean up the older warnings.
There was some discussion of allowing one or two hyphens to specify
command-line options. Michael Meffie supplied a patch to allow this and
it was approved. This feature will be included in a future release.
The OpenAFS web site is now using git for source control, and the older
CVS repository for the web site has been disabled.
Jeff Altman and Derrick Brashear gave a status update on OpenAFS
progress at the European AFS Meeting. Your File System Inc. has
committed to working on several improvements to OpenAFS and contributing
them back to OpenAFS. There is more information in the Jeff & Derrick's
slides at <http://www.dia.uniroma3.it/~afscon09/docs/part1.pdf> and
<http://www.dia.uniroma3.it/~afscon09/docs/part3.pdf>. There is an
updated road map at <http://www.openafs.org/roadmap.html>.
There is some discussion about getting rid of the AFS lock icon in the
Windows system tray for future versions of AFS. A few people value the
clear indication that the lock icon gives for being logged in. Please
join in the discussion on the openafs-info mailing list.
On September 22-24, an AFS Hackathon was held at The School of
Informatics at the University of Edinburgh. Simon Wilkinson posted a
summary on the openafs-devel and afs3-standardization mailing lists. The
summary is available at
The jabber chat logs of the Hackathon are available at
European AFS Meeting
The Second Annual European AFS Workshop was held at Roma Tre University,
Italy, on September 28-30, 2009.
The attendance of the event remained stable at about 50 people from 6
countries, including two colleagues from Pilsen, Czech Republic. There
was an introductory day, a day dealing with advanced topics, and a final
half-day dedicated mainly to site reports. Social activities consisted
of a sponsored bus tour through Rome (Sun Microsystems), a sponsored
visit to St Paul's Basilica (DIA Roma Tre), the second largest cathedral
after St. Peter's, and two dinners in typical Roman restaurants, where
the attendants proudly consumed more wine than water.
Thanks to INFN, this year Jeffrey Altman and Derrick Brashear were again
the invited guests, and Hartmut Reuter provided a detailed tutorial on
the combination of AFS with object storage. The slides of all talks are
available on the website, and the event was transmitted in real-time
streaming, provided by ENEA. Recordings can be freely accessed over the
This workshop was a joint effort of the Department of Informatics and
Automation from Roma Tre University, and three research institutions:
CASPUR, ENEA, INFN. Two industrial sponsors contributed: E4 company and
The next year's conference will be hosted either in Pilsen, Czech
Republic, or Hamburg, Germany.

Annual Best Practices Workshop
Plans are already underway for the seventh Workshop, to be held May
24-28, 2010, at the University of Illinois at Urbana-Champaign. We hope
to see you there.
AFS Protocol Standardization
There is some progress in afs3-standardization. There are new protocol
descriptions for rxgk, rxk5, and Rx/OSD that were published in advance
of the hackathon, I just submitted a proposal for SRV records for AFS,
and I think there was an extended callback draft published as well.
Current active protocol drafts:
* AFS Callback Extensions
* DNS SRV Resource Records for AFS
Demand-Attach FileServer (DAFS)
* Andrew Deason <email@example.com>
* Tom Keiser <firstname.lastname@example.org>
* Mike Meffie <email@example.com>
A fix for 124484 (volumes not salvaged on first access from volserver)
is nearing completion, and should see public review soon. 124484 may be
the last critical DAFS bug; we are currently trying to reproduce
earlier-seen problems with the newest patches to see if they still
We are also working on improved developer documentation for DAFS, as it
has been noted that a lack of a broad overview for the changes DAFS
brings (specifically in the volume package) has made contributions and
review prohibitively difficult for newcomers to DAFS code.
Mac OS X OpenAFS Preference Pane
* Claudio Bisegni <Claudio.Bisegni@lnf.infn.it>
The MacOSX Preference Pane has been updated to use the launchd start
mode. StartupItems has been replaced by the launchd technology. The
behavior of the OpenAFS service at start-up can be managed from the
Preference Pane. Both the launchd daemon and the preference pane use the
/Library/OpenAFS/Tools/root.client/usr/vice/etc/afs.rc file to start or
Extended Callback Information
* Matt Benjamin <firstname.lastname@example.org>
XCB was discussed at Edinburgh, and at the request of the group, a new
I-D draft was published, removing mention of asynchronous delivery. That
feature will be revisited in future. The XCB draft is under last call,
and interested parties are requested to review the draft and send
comments or indication of "support" or "not support" to the
A draft document of the protocol changes is available at

I am gradually sending changes indirectly related to NetBSD cache
manager port. The most recent are related to AFS_PROC and AFS_UCRED.
Kerberos v5 and multiple encryption types

Google Summer of Code 2009
OpenAFS received four slots for the 2009 Google Summer of Code.
Go to <http://socghop.appspot.com/org/home/google/gsoc2009/openafs> for
more information about the GSoC projects.
The Google Summer of code is over for this year. The code from the three
active GSoC projects is available at
OpenAFS Server Preference Based on Network Conditions
Student Developer: Jake Thebault-Spieker <firstname.lastname@example.org>
Mentor: Derrick Brashear <email@example.com>
The server preferences project has implemented code for the Windows
platform to rank servers based on packet round-trip time which is
currently available in gerrit. Using throughput as well will have
updated code in gerrit soon (although this is still a work in progress).
Upon getting code that seems reasonable for the Windows platform, the
Unix port should be a matter of re-implementing the code, but not
changing too much. I hope to have the unix port completed within a
Even though the Google Summer of code has ended, Jake will continue
working on the project until completion. He is still working within the
original specifications of the project.
A presentation about Jake's work was given at the European AFS Workshop
Projects with no progress or no update
* Disconnected AFS support
* Pthreaded Ubik
* Rx OSD integration & Raw Vicep Access in Clients
* Userspace cache manager
* Better Documentation
