General OpenAFS Progress

1.5.74 was released on April 22. It includes many fixes and improvements, including updates for FreeBSD 8.0, and an experimental FUSE client among other improvements.

Testing continues for the 1.5.X series on Unix platforms. There is a patch (commit 14195f0f) in git against 1.5.74 that fixes a kernel panic on RHEL 6 Beta. The kernel panic affects OpenAFS versions 1.5.66 through 1.5.74.

On RedHat Enterprise Linux (RHEL) 6 Beta and Fedora 12, there is an issue where the kernel generates large volumes of system log traffic when the AFS disk cache is accessed. RedHat Bugzilla entry #584901 https://bugzilla.redhat.com/show_bug.cgi?id=584901 is tracking this issue and includes a fix for the issue. The RedHat kernel team is reviewing the patch for possible inclusion in the production release of RHEL 6.

The 1.4.x versions of OpenAFS don't work with Linux kernel 2.6.34. Version 1.4.12.1 will be released to deal with that

Some groundwork has been started for read/write replication based on Vishal Powar's code from the 2008 Google summer of code. The code requires a new RPC protocol between fileserver. A standards proposal is planned for documenting the new protocol.

Adam Megacz reported success while using an unauthenticated 1.4.11 client on an Apple TV.

AFS Protocol Standardization

Informal drafts that haven't been uploaded to the IETF web site:

Rx Spec:

http://openafs.sinenomine.net/~mmeffie/rfc/draft-zeldovich-rx-spec-00.html

This draft is in the very early stages. Mike Meffie and Tom Keiser are the current owners of this proposal. A formal specification of Rx is needed as a basis for other IETF proposals.

Discussion on these proposals is welcome and should be done on the AFS3-standardization list at http://michigan-openafs-lists.central.org/mailman/listinfo/afs3-standardization

PTS Alternate Authentication

http://tools.ietf.org/html/draft-brashear-afs3-pts-extended-names

Status: Third Draft

AFS Callback Extensions

http://tools.ietf.org/html/draft-benjamin-extendedcallbackinfo

Status: Active - Waiting on RPC refresh

This proposal will be rewritten with references to the RPC time refresh.

Last update: September 23, 2009

DNS SRV Resource Records for AFS

http://tools.ietf.org/html/rfc5864

Status: Published

The draft was accepted and published as RFC 5864.

RXGK

http://tools.ietf.org/html/draft-wilkinson-afs3-rxgk

Status: Active

Rxgk is a security layer for AFS which will support strong encryption and authentication through Kerberos v5, GSI and any other GSSAPI security mechanism.

Changes which are considered suitable for the 1.5.x series are in git - look for changes with author sxw@your-file-system.com. A development tree, which will be frequently rebased, is at http://github.com/your-file-system/openafs-rxgk

Last Update: Jan 9, 2010

AFS3 ACL Rights

http://tools.ietf.org/html/draft-deason-afs3-acl-restrictions

Status: Second draft

Last update: January 13, 2010

See the Per-File ACLs section for more info.

Rx Security Object Providing Cleartext Peer Identity Assertions

http://tools.ietf.org/html/draft-tkeiser-rxrpc-sec-clear

Status: Third draft

Last Update: April 17, 2010

I released a new version of the Rx Clear security class I-D the other day. I am hereby soliciting comments on this new version of the draft.

AFSVol Tag-Length-Value Remote Procedure Call Extensions

http://tools.ietf.org/html/draft-tkeiser-afs3-volser-tlv

Status: Second Draft

Last Update: April 6, 2010

As new forms of metadata are added to AFS volumes, we are running into limitations with the wire volume metadata structures used by the volume server. This internet draft aims to standardize a tag-length-value (TLV) encoding for arbitrary AFS volume metadata. A new version of this draft was released on April 6th, 2010. Everyone is invited to review and comment on this document. Comments should be sent to the afs3-standardization@grand.central.org mailing list.

--Tom

AFS Byte-Range File Locking

http://tools.ietf.org/html/draft-mbenjamin-afs-file-locking

Status: Fifth Draft

This draft proposes protocol extensions to support byte-range and mandatory locking.

The first draft was submitted on May 5, 2010.

Projects

Demand-Attach FileServer (DAFS)

Project Contacts:

Gerrit 1092 (initialization volume lock contention) has been merged, which should speed up DAFS startup on fileservers with large numbers of volumes. An important fix has been discovered by Simon Wilkinson in gerrit 1832, which is undergoing review. Several thread-safety fixes to the salvaging code has culminated with gerrit 1865 (undergoing review), which allows for multiple I/O threads in salvages, potentially providing salvage speed improvements. Gerrit 1562 (positional I/O; required for new improvements) is still undergoing review, but has made much recent progress.

--Andrew

Better Documentation

Project Contacts:

IIRC, we merged some XML document updates, but most of the work was on the man pages. People have been doing very well about submitting documentation changes with changes that need documentation. Some improvements to the demand-attach file server documentation were merged, although there are still some undocumented binaries in a demand-attach build (I believe man pages for them are currently being worked on).

Pthreaded Ubik

Project Contact:

This code has been merged into the master branch. It will not appear as a separate project in future newsletters.

Per-File ACLs

Project Contacts:

Current status:

The published code on github for per-file ACLs has the following new features:

The github fork is at http://github.com/mdionne/openafs, and the most current work is in the per-file branch, which should be the default branch.

--Marc

*BSD Support

Project Contacts:

Added Support for NetBSD 5.0, and added conditionals for FreeBSD 8.1 and 9.0.

Userspace cache manager

Project Contact:

All recent related changes have been merged, and Debian packages containing the FUSE OpenAFS client should be in Debian soon, thanks to Russ Allbery. Modern libuafs perl bindings are still forthcoming, but should be available before the workshop this month.

--Andrew

Rx OSD integration & Raw Vicep Access in Clients

Project Contacts:

The cell ipp-garching.mpg.de is currently switching production servers to openafs-osd based on 1.4.12. Hartmut Reuter started to port the extensions to 1.5.x. Debian and possibly ubuntu packages of openafs-osd are available soon. --Christof

SetAG

Project Contact:

Due to lack of resources and development time SetAG has to be considered a discontinued project, sorry. We had no possibility in the last months of working on updating our code to follow changes in openafs so definitely I think that the project has to be rethinked from scratch.

--Alberto

Unix Support for AppleDouble files (Posix Attributes)

Student Developer: Kelli Ireland <kelli.ireland@gmail.com>

Mentor: Derrick Brashear <shadow@gmail.com>

Self-intro: https://lists.openafs.org/pipermail/openafs-devel/2010-May/017582.html

Abstract:

AppleDouble files, commonly used to store metadata and extended attributes in filesystems without native support for them, would be supported by all POSIX-compliant OpenAFS platforms. This would provide a means to allow client-side extended attribute support to be added in a backward-compatible manner without requiring changes to the AFS file servers. It also opens the door for future protocol changes to be made, if better accommodation of metadata and extended attributes is desired.

Encrypted Storage

Student Developer: Sanket Agarwal <sanket@sanketagarwal.com>

Mentor: Simon Wilkinson <sxw@inf.ed.ac.uk>

Self-intro: https://lists.openafs.org/pipermail/openafs-devel/2010-March/017424.html

Abstract:

The AFS protocol offers encryption for data transport from client to server. However, that data is stored on the server in cleartext, where it can potentially be read by the administrators of that server. This poses a real world problem for organisations who wish to outsource the provision of their file storage, whilst keeping their data confidential. This project would augment the existing AFS client to support encrypting data blocks before sending them to the file server.

Apply the kafs project of OpenAFS

Student Developer: Lei Wang <wang840925@gmail.com>

Mentor: David Howells <dhowells@redhat.com>

Self-intro: https://lists.openafs.org/pipermail/openafs-devel/2010-April/017493.html

Abstract:

Last year, I have took the project, and as a student of GSoC2009. I have finished partly a task, as Linus and some of the Linux community against implement pioctl() directly in the kernel. We used other ways to talk to the kernel after we gave up some implementation that have done. There is my project idea and time line at last. My major is distributed file system. As I have some experience of my research and this project, I think I could do it well.

Port OpenAFS to NetBSD

Student Developer: Matt Smith <matt.j.sm@gmail.com>

Mentor: Matt Benjamin <matt@linuxbox.com>

Self-intro: https://lists.openafs.org/pipermail/openafs-devel/2010-March/017450.html

Abstract:

Around the same time the original Linux port of AFS was done, a port to NetBSD was also available. While NetBSD has evolved, the original AFS port did not keep pace. Since then, a port to NetBSD has been highly desired. This project will port the OpenAFS client to run on NetBSD.

An open source version of the Microsoft Safe String Library

Student Developer: Jonas Sundberg <jonas.sundberg@gmail.com>

Mentor: Jeffrey Altman <jaltman@secure-endpoints.com>

Self-intro: https://lists.openafs.org/pipermail/openafs-devel/2010-May/017602.html

Abstract:

A cross platform implementation of the Safe String Library (StrSafe.h) provided by Microsoft. The library will allow multi platform software to use a single library for safe string operations. This will reduce the risk for buffer overflows and will increase code sharing between code for different platforms.

A lot of focus will be put on unit testing of the library thoroughly. This will make it easier to be confident in the correctness of the library.
