Welcome to the home of OpenAFS

What is AFS?

AFS is a distributed filesystem product, pioneered at Carnegie Mellon University and supported and developed as a product by Transarc Corporation (now IBM Pittsburgh Labs). It offers a client-server architecture for federated file sharing and replicated read-only content distribution, providing location independence, scalability, security, and transparent migration capabilities. AFS is available for a broad range of heterogeneous systems including UNIX, Linux,  MacOS X, and Microsoft Windows

IBM branched the source of the AFS product, and made a copy of the source available for community development and maintenance. They called the release OpenAFS.

OpenAFS Foundation

The OpenAFS Foundation is dedicated to fostering the stability and growth of OpenAFS by providing strategic direction and aiming to raise money to support the development and maintenance of OpenAFS. More information on the Foundation can be found on the OpenAFS Foundation website.

OpenAFS 1.8.7 is the next release in the current stable series of OpenAFS releases for UNIX/Linux systems. It fixes a critical issue in the generation of Rx connection IDs that prevent Rx clients started after 14 Jan 2021 08:25:36 AM UTC from being able to successfully make connections. In addition to cache managers and client utilities, fileservers and database servers are also affected, since they initiate connections to (other) database servers during their normal operation.

The issue occurs only at startup, while generating the initial connection ID, so cache managers or servers that were already running at the time in question will not be affected until they restart.

20 September 2015 - OpenAFS adopts Contributor Covenant as code of conduct

In the interest of fostering a friendly, welcoming environment for contributors, we have introduced the Contributor Covenant as the code of conduct for the OpenAFS Project. A copy is included in the source tree, and can be found via the Contributor Code of Conduct link included on all pages. For additional information, visit contributor-covenant.org

17-September-2015 - OpenAFS 1.6.14.1 - Maintenance release for UNIX/Linux

OpenAFS 1.6.14.1 is the next in the current series of OpenAFS stable releases for UNIX/Linux systems. It adds client support for Linux kernel 4.2 . Note that due to changes to internal data structures with this kernel release, the OpenAFS client can no longer reset the link count during path lookups. Since volume root directories must behave like symlinks instead of normal directories in order to satisfy Linux kernel invariants, looking up paths containing more than 40 mount points will fail with ELOOP on such kernels. There are no further changes. Systems not affected by the Linux 4.2 VFS changes can continue to use the OpenAFS 1.6.14 release.

For more information:

13-August-2015 - OpenAFS 1.6.14 - Maintenance release for UNIX/Linux

OpenAFS 1.6.14 is the next in the current series of OpenAFS stable releases for UNIX/Linux systems. It is limited to a fix for an issue introduced in release 1.6.13: Prior to the OpenAFS security release 1.6.13, the Volume Location Server (vlserver) RPC VL_ListAttributesN2() supported wildcard volume name lookups via regular expression (regex) pattern matching. This support was completely disabled in 1.6.13 because it was judged to be a security risk due to buffer overruns in the implementation, as well as the possibility of denial of service attacks where certain regular expressions could cause excessive CPU usage in some regex implementations. After 1.6.13 was released, it was discovered that the native OpenAFS 'backup' system uses the VL_ListAttributesN2() regex support to evaluate configured volume sets.

As a result of this issue, OpenAFS 1.6.14 replaces the 1.6.13 changes to VL_ListAttributesN2. 1.6.14 prevents the buffer overruns and reenables the regex support, but restricts it to OpenAFS super-users and -localauth only. This is sufficient to restore the OpenAFS 'backup' system's ability to work correctly with any previously supported volume set. The OpenAFS 'backup' commands are already documented to require super-user authorization, so this restriction is moot for the backup system. i

None of the other security fixes in OpenAFS 1.6.13 are known to have any issues, and are still included unchanged in OpenAFS 1.6.14.

20-Mar-2007 - OpenAFS Security Advisory 2007-001

Unix clients in OpenAFS versions before 1.5.17 and 1.4.4 allow a potential privilege escalation via setuid functionality which can be enabled by the client administration but is enabled by default for the client's local cell. To avoid this issue, 1.5.17 and 1.4.4 have been issued with setuid disabled by default in all cases.

28-Dec-2006 - OpenAFS Elders announce "No More DES" roadmap

AFSv3 was designed and implemented during the late 80s and early 90s when the state of the art in distributed computer authentication and data confidentiality was to use Kerberos 4 and the United States' Data Encryption Standard (DES). Over the last two years the U.S. National Institutes of Standards and Technology (NIST) has withdrawn the DES standard and MIT has announced the end of life of Kerberos 4. In response, the OpenAFS Elders have approved a roadmap to transition from DES to stronger ciphers which includes the deprecation of the OpenAFS kaserver.

6-Dec-2006 - pam-afs-session 1.0 released

pam-afs-session is a PAM module intended for use with a Kerberos v5 PAM module to obtain an AFS PAG and AFS tokens on login. It puts every new session in a PAG regardless of whether it was authenticated with Kerberos and runs a configurable external program to obtain tokens. It supports using Heimdal's libkafs for the AFS interface and falls back to an internal Linux-only implementation if libkafs isn't available.
