Freenet 0.7.5 build 1490 is now available.

This release provides three different changes:

  • streaming in the browser,
  • mitigating the pitch black attack, and
  • providing the windows-installer from the node again.

For streaming, it builds on the m3u-filter to provide direct in-browser streaming. Currently it works with audio (mp3 and ogg vorbis) and video (ogg theora) in sufficient quality for music playlists and specially crafted video-streams.

With this change, adding a media-tag that references an m3u-list like

<audio src="stream.m3u" controls="controls">
<a href="stream.m3u">stream.m3u</a>
</audio>

or

<video src="stream.m3u" controls="controls">
<a href="stream.m3u">stream.m3u</a>, starting with <a href="sff-001.ogv">sff-001.ogv</a>.
    Putting the first video here causes freesitemgr to more likely
    put the first video into the container, giving faster initial startup.
</video>

gives you a media-tag that plays the m3u-playlist. In Sharesites you need to add at least one space before the tag.

If you want to stream via Freenet yourself, you’ll find help in a thirdparty howto.

There are three example sites:

  • Audio-Playlist: USK@1wpsnrzb9fiFmmq6OozoZ0Mnk376AlizUKjKPh3TXwM,CwfRO8X0xaCUzH28eoHigxUV-5TkRV8hCoQdO2kmsQM,AQACAAE/streaming-over-fproxy/3/
  • Streaming Video: USK@UGh1rxaHczJVr4k4LwxWrxFBc-Dt5P0F3IuPONpp8ZQ,klWF5g9B2PLst8tRO8c9tzk6XvisGynFVJRzM8-9718,AQACAAE/stream-36c3-sff/3/
  • Radio Interview: USK@4DQ15JpGlVGDdyXvQE3Egz7SLK2TzMAUmp~aptnwyt4,ljFASreV8AHaQhscfrNLuVyl3qksltgP9sndtLuUHB8,AQACAAE/stream-radiocc-freenet/1/

This follows an old idea to enhance freesites with strictly checked interactivity, similar to userscripts but without the security implications of adding a script that might have a very different threat model than Freenet itself.

Also this release ships a mitigation for the pitch black attack. For details see https://www.mail-archive.com/devl@freenetproject.org/msg55182.html

Mitigating the pitch black attack is supported by NLnet as part of the NGI0 PET Fund. For details see https://nlnet.nl/project/Freenet-Routing/ Thank you!

There are still more tests needed to ensure that the change suffices to resolve the main objection that existed among people well-versed in the technical background of Freenet, GNUnet, and others against using the friend-to-friend mode of Freenet since 2007.

It used to be far too easy to break a pure friend-to-friend net (all nodes using high-security mode). This should be resolved now.

And finally the UOM transfer max sizes were tripled, so the windows-installer provided by Freenet nodes gets updated again, and the annoying warning about freenet-latest-installer-windows.exe during install and update disappears.
