A vulnerability was discovered in all versions from 1.3.0 to 1.8.2 and 1.9.0a1. This vulnerability allowed a malicious attacker to delete files. To be able to delete the file, an attacker must know its 'storage index'. An upgrade to 1.8.3 resolves this issues. The `known issues document`_ provides the technical information regarding this issue. .. _1.8.3: http://tahoe-lafs.org/pipermail/tahoe-dev/2011-September/006675.html .. _known issues document: http://tahoe-lafs.org/trac/tahoe-lafs/browser/trunk/docs/known_issues.rst Announcing the Second International Tahoe-LAFS Summit ----------------------------------------------------- The *Second International Tahoe-LAFS Summit* will take place November 7 through November 11, in San Francisco. `Mozilla`_ |mozilla| has generously offered to host us in their nice new San Francisco office. (`Google`_ |google|, `Adobe`_ |adobe|, and `Microsoft`_ |microsoft| also offered to help out in case Mozilla's facilities weren't availablebthanks to them as well.) The Summit will have technical presentations of new features, design discussions, and probably a lot of coding! There will be live audio and video available for remote participants. `Help us organize the Summit`_ on the wiki. .. _Help us organize the Summit: http://tahoe-lafs.org/trac/tahoe-lafs/wiki/Summit .. _Mozilla: https://www.mozilla.org .. |mozilla| image:: Mozilla_logo-35x35.svg :height: 35 :alt: Mozilla :target: https://www.mozilla.org .. _Google: https://google.com .. |google| image:: Google-logo-x35.svg :height: 35 :alt: Google :target: https://google.com .. _Adobe: https://www.adobe.com .. |adobe| image:: Adobe_logo-x35.svg :height: 35 :alt: Adobe :target: https://www.adobe.com .. _Microsoft: https://www.microsoft.com .. |microsoft| image:: Microsoft_Logo_Historical.svg :height: 25 :alt: Microsoft :target: https://www.microsoft.com 1.9.0a2 Release --------------- 1.9.0a2_ was released. In addition to the security fix mentioned above, this release incorporates the following fixes: * 'tahoe debug' commands now understand MDMF caps and shares (`#1507`_) * Recent Uploads And Downloads shouldn't miss 'tahoe put' (`#1079`_) * tests run slightly faster, still kinda painful * 'tahoe put --mutable-type=.." implies --mutable * fewer dropped errors (and lost-progress bugs) in mutable retrieve * tolerate linux-3.0 in platform detection code (`#1536`_) The following work remains for the 1.9.0 release: * docs improvements * minor fixes: really really minor * packaging tests * Foolscap needs a new release, so make sure Tahoe-LAFS is compatible We highly encourage everyone to throughly test this release. The more bugs we find in the alpha, the less in the beta and the quicker 1.9.0 arrives. Currently, there is a possibility of a Halloween release of 1.9.0. .. _1.9.0a2: http://tahoe-lafs.org/pipermail/tahoe-dev/2011-September/006697.html .. _#1507: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1507 .. _#1079: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1079 .. _#1536: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1536 tahoe-lafs.org Outage --------------------- tahoe-lafs.org `experienced multiple outages`_ over the last several days. The outages were the result of a router which was acting up. The router has been replaced. We apologize for any inconvenience these outages may have caused. We are in the process of migrating the server to a new virtual server with professional hosting instead of being an old server humming away in someone's garage. .. _experienced multiple outages: http://tahoe-lafs.org/pipermail/tahoe-dev/2011-October/006701.html Free/Open Source Project of the Week ==================================== The *Free/Open Source Project of the Week* is HekaFS_, formerly known as "CloudFS". Like Tahoe-LAFS, HekaFS offers provider-independent confidentiality by encrypting all of the data on the client side, with an encryption key unknown to the server. It is built on top of GlusterFS_, and it inherits most of the performance and scalability of GlusterFS. It also has the same network and filesystem semantics of GlusterFS. In contrast, Tahoe-LAFS invents new semantics such as provider-independent immutability. The HekaFS project is lead by Jeff Darcy |jeffdarcy| and sponsored by RedHat |redhat|. In addition to sponsoring HekaFS, RedHat just announced that they are buying the Gluster company. .. _HekaFS: http://hekafs.org .. _GlusterFS: http://gluster.org .. |jeffdarcy| image:: jeff_darcy-bw.png :height: 35 :alt: Jeff Darcy :target: http://pl.atyp.us .. |redhat| image:: RedHat-logo-x35.svg :height: 35 :alt: RedHat :target: https://www.redhat.com/ Commercial Supporter of the Week ================================ The Tahoe-LAFS project would like to thank `Atlas Networks`_ |AtlasNetworks| for their generous donation of four servers. In addition to the generosity of their hardware donation, Atlas Networks provide the Tahoe-LAFS project with remote consoles and technical support, including complete OS reinstalls. .. _Atlas Networks: http://atlasnetworks.us .. |AtlasNetworks| image:: AtlasNetworks.png :height: 35 :alt: Atlas Networks :target: http://atlasnetworks.us

Performance Measurements ------------------------ Brian Warner |brian| has been using the Atlas Networks servers to do performance measurements of Tahoe-LAFS. These measurements `show some performance issues`_, including one that arises when using large values of K (number of shares needed). Ticket 1264_ has details. .. _1264: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1264 .. _show some performance issues: .. http://tahoe-lafs.org/pipermail/tahoe-dev/2011-September/006683.html Tahoe-LAFS web-app ------------------ Brian Warner `suggested`_ the notion of a "Tahoe-LAFS web-app", in which both the data and the code (Javascript) are stored in a Tahoe-LAFS grid and the browser loads them and runs the Javascript app. This would have a similar effect to the `TiddlyWiki-on-Tahoe-LAFS`_ hack, and to the `Unhosted`_ |unhosted| project. .. _TiddlyWiki-on-Tahoe-LAFS: http://tahoe-lafs.org/trac/tiddly_on_tahoe .. _Unhosted: http://unhosted.org .. _suggested: http://tahoe-lafs.org/pipermail/tahoe-dev/2011-September/006690.html .. |unhosted| image:: unhosted-logo.png :height: 35 :alt: Unhosted :target: http://unhosted.org Ifconfig Error Message ---------------------- Kill Your TV posted an issue with `Arch Linux and 1.8.3`_. The issue was the result of the inability of tahoe to find ifconfig. Ticket `#1536`_ was opened to provided more user friendly error messages involving finding and using ifconfig. .. _Arch Linux and 1.8.3: .. http://tahoe-lafs.org/pipermail/tahoe-dev/2011-September/006676.html Patch Needing Review of the Week ================================ There are six (6) tickets still needing review for 1.9: * 393_: MDMF * 1265_: New Visualizer is insufficiently labelled/documented (plus layout problem) * 1398_: make docs/performance.rst more precise and accurate * 1547_: the WUI controls for setting the type of an uploaded file are confusing * 1552_: web-API: replace ?mutable-type with ?format={chk,sdmf,mdmf} * 1556_: fix bugs found by 'check-miscaptures' script Let's see if we can't get these reviewed and 1.9 out the door. .. _393: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/393 .. _1265: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1265 .. _1398: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1398 .. _1547: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1547 .. _1552: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1552 .. _1556: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1556 ---- *The Tahoe-LAFS Weekly News is published once a week by The Tahoe-LAFS* *Software Foundation, President and Treasurer: Peter Secor* |peter| *.
