  1. OpenAFSStatus Report Cartel 2008 Stanford University

  2. Starting with Microsoft Windows • 1.5.50 being released soon (as of press time). • First build with Unicode support! • Previous recommended release: 1.5.39

  3. Major New Features in the last year • Vista SP1 and Server 2008 Certification • Performance Improvements • Hash tables, Lock management redesign, Interlocked operations for reference counts • The client service has been profiled and bottlenecks removed. Up to 63 MB/sec on 64-bit Vista SP1 • Failover Improvements • RXKAD errors and Idle Data • Directory Searchs • B+ trees and local directory modifications

  4. More Improvements • Token management improvements • Try home realm first • No longer destroy token after RXKAD errors • Volume Status Tracking • Volume Notification Plug-in Interface • Rx multi Server Probes • Volume Group Management

  5. 2008-2009 Plans • Native File System Client • Support for DOS and Extended Attributes • New user interfaces • Explorer Shell Extensions • Management Console plug-ins • Control Panel replacement • AFS Servers • http://www.secure-endpoints.com/openafs-windows-roadmap.html

  6. Got Questions About OpenAFS on Windows? • OpenAFS for Windows Status Reports available at • http://www.secure-endpoints.com/ • Mailing List • openafs-win32-devel@openafs.org

  7. And moving on to Unix • 1.5.50 includes • Support for new Tivoli TSM X/Open API libraries. • Patches for a regression in the Demand Attach Fileserver which could crash due to a race during volume moves. • A fix for a bug where clients might get VNOVOL during a volume release which has existed since pre-OpenAFS. • And then there are older updates. 7

  8. MacOS X • Few remaining issues. • And most just need a little time to kill them. • http://www.openafs.org/macos.html • Getting tokens at login is (now) “hard”. • Interface for Kerberos plugins is a moving target. • AFSCommander tool available. • Integration coming. • Some bugs remain.

  9. Linux • iget() is dead. • Cache manager opens files by path, as in OSX 10.5, to deal. • ARM port (Nokia n-Series support). • Usual AFS write-on-close semantics restored in 1.4.7, where possible. • The persistent “svn issue” is resolved in 1.5.50.

  10. Clients • Interaction issues with various GUI environments have been addressed. • When shutting down, the client now tries much harder to deallocate resources. • It also now tries to tell you when it failed, so you may think you have new problems. • Erroneous token destruction from RXKAD errors is also fixed. (1.5.50)

  11. Servers • Clients could tie up too many fileserver resources. • A quota is enforced during TellMeAboutYourself/WhoAreYou from the fileserver. (corrected in 1.4.7) • Servers and clients enforce dead time on calls. No more meltdowns. (1.5.39) • For security reasons a period (“.”) in your Kerberos v5 principal names was verboten. • Arguably misguided. Can be overriden by switch. (1.4.7)

  12. And then there’s test releases • We want to issue 1.6. Help us test! • Split cache (dedicated portion for read-write data) has had issues addressed. • Linux NFS translator fixes. • Multiple (more than 2) local realms. • Partition size limit increased (well) beyond 2TB. • Readonly “disconnected AFS” for Unix clients. • Cache readahead. • Performance improvements at the network level.

  13. And some near-term coming attractions • Cache bypass when you’ll never read it again. • Extended callback messages to optimize away unneeded traffic. • Integration of and updates to Rxk5 and AFS object storage.

  14. Non-technical discussions • First year for Google Summer of Code participation. • Midterm just passed. • Most students show promise. • Organizational futures • Foundation incorporation just waiting on result of AFS trademark discussion with IBM. • A strawman of an independent standardization process written by Simon Wilkinson is now available
