OpenAFS Newsletter, Issue 3, July 2009
Welcome to the third issue of the OpenAFS newsletter. The newsletter
summarizes what is happening in the OpenAFS community. The main thing to
report in this issue is the conversion of CVS to git. Git is now ready
for use in development. I suspect that many people were very busy or on
vacation this month, because many of the subprojects did not reply to
requests for project updates.
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 <[email protected]> know what you would
like to see out of this newsletter.
The current and past issues of this newsletter are available at

General OpenAFS Progress
Many thanks go to Simon Wilkinson for finishing the conversion from CVS
to git and setting up gerrit. Gerrit has only been up for a week and
there are already over 100 patches that have been merged!
1.4.11 has been released, and it includes major bugfixes for Linux
clients and fileservers. Some minor bugs were fixed on other platforms.
The release notes are available at
http://www.openafs.org/frameset/dl/openafs/1.4.11/RELNOTES-1.4.11
Events
AFS Hackathon
The School of Informatics at the University of Edinburgh will be hosting
an AFS Hackathon 22-24 September (immediately before the European AFS
Conference). All OpenAFS developers are welcome to attend - please see
the email to openafs-announce for details, and RSVP to [email protected]
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.
Projects
Security Releases
Security Officer:
* Simon Wilkinson <[email protected]>
No security issues since 1.4.9, 1.4.10, and 1.5.59 were released in
April 2009.
Git
Project Contact:
* Simon Wilkinson <[email protected]>
During the week of 6th July, we completed our transition to the git
version control system. Git, and gerrit (our code review tool) are now
ready for use! See
http://www.dementia.org/twiki/bin/view/AFSLore/GitDevelopers for more
details.
Pthreaded Ubik
Project Contact:
* Steven Jenkins <[email protected]>
The pthreaded ubik's initial code delivery to provide for use of POSIX
threads instead of LWPs was made in April 2008. After some production
usage, some problems were found in initialization (on certain platforms)
and lack of locking, leading to data corruption in some cases for the
vlserver. As part of the analysis of these problems, some differences
were identified between the private version of OpenAFS being used and
the version in OpenAFS HEAD, several other longstanding issues with vos,
vlclient, and the vlserver were identified, and some patches have been
submitted:
* RT #124977 addresses mutex and condition variable initialization
* RT #125035 fixes a longstanding logging bug
* RT #125036 fixes a longstanding bug in vlclient command-line parsing
Current work involves cleaning up and testing a patch to fix improper
handling of multi-homed IP addresses in the VLDB. The patches to fix the
logging are undergoing further testing and analysis (both code review
and automated testing with Helgrind), and we hope to have those
submitted soon as well.

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.
Three of the projects are still active. Unfortunately, one student had
to back out.
The following projects did not give a status update:
* Implementing OpenAFS Features into RedHat's kafs Kernel Module
* OpenAFS Server Preference Based on Network Conditions
OpenAFS Management Console on Windows
Student Developer: Brant Gurganus <[email protected]>
Mentor: Jeffrey Altman <[email protected]>
Self-intro:
<https://lists.openafs.org/pipermail/openafs-devel/2009-April/016591.htm
l>
The Google Summer of Code program is at its half way point. With that,
the management console has a complete user interface as well as
deployment packages. Project downloads and source will be available at
http://code.google.com/p/openafsclientmmc
Projects with no progress or no update
* Binary Packaging
* Better Documentation - No significant updates.
* BSD support
* Disconnected AFS support
* Extended Callback Information
* Kerberos v5 and Multiple Encryption Types
* Rx OSD integration & Raw Vicep Access in Clients
Resolved Tickets
Since Gerrit is now the preferred method of accepting patches instead of
RT, it's likely that fewer RT tickets will be filed.
