and at:<br><br><a href="http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.8.13-3/">http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.8.13-3/</a><br><br>I want to clearly note that I can crash the router over wifi using the rrul test easily. I can (furthermore) crash the x86 linux-3.9.2 iwl driver on my laptop even more easier than I can crash the router. The combination of the two problems are making debugging impossible.<br>
<br>So... pretty please... with sugar on top... don&#39;t install this on your default gw?<br><br>If on the other hand, you have a jtag debugger handy, and don&#39;t have a iwl card on your laptop, and can look into the wifi issues, please do so... (all you have to do is bump up /etc/xinetd.d/netserver to 16 and run the netperf-wrapper against it for a few minutes)<br>
<br>There are otherwise a huge number of interesting things that have accumulated for this release cycle.<br><br>I was very happy that most of what was in Modena has landed in openwrt and the mainline linux kernels last month. Relieved, actually. I felt that I could take a break... even thought I could quit... spent a few days on a beach in Morocco and got bored to death... so....<br>
<br>The BIG new thing in this release is a version CISCO&#39;s PIE AQM algorithm, which after nearly a year of development and analysis was released as open source last week. The version of pie I just put in cero has not been fully verified to be correct, but has the additional features of ECN and TSQ support over the original. I hope to bake this a lot more over the coming week. (the wifi issue is annoying but secondary at the moment to finally! finally! fiddling with PIE)<br>
<br>There was the usual huge resync with openwrt. dslite landed recently in particular, but there have just been a huge number of updates across the board that I&#39;ve lost track of. FW3 for example, is a fast, in-c replacement for the old firewall scripts, and openwrt is now using multi-table support in preparation for handling src/dst routing better.<br>
<br>Toke contributed tahoe-lafs and suggested trying out the tinc vpn system, so those are available as an optional package. tinc is kind of neat. a meshy vpn system. Never heard of it before now.<br><br>Toke also has been a great help elsewhere, notably in getting a gui and scripts going for the backend AQM system, working on a new build script to make it easier for others to build cero, and lots, lots more.<br>
Rich Brown &amp; Toke updated the onboard documentation significantly<br>Electra convinced me to make batman-adv available (but not enabled) by default<br>Babeld 1.4 has a new convergence smoothing algorithm (but quagga-babeld is still the default)<br>
OpenWrt&#39;s QOS web page and backend scripts have been replaced by the new AQM page<br>The AQM scripts are now correct for EF and ECN.<br>fq_codel is now the default on everything with a quantum of 300<br><br>I have a very long list of things I&#39;d like to see land in a stable version of this before ietf Berlin (late july) - notably a ton of good stuff happened in the linux-3.9 and current net-next series on the TCP front. sctp support, maybe even mptcp support is looking semi-feasible.<br>
<br>only a package definition away from npt-66 support at this point, no userspace dependencies left... anyone?<br><br>want better dlna and upnp support, too. Have no idea what&#39;s needed to fix minidlna<br><br>And there&#39;s GREAT things happening in dnsmasq that I doubt will land anytime soon, but here&#39;s hoping. I ended up talking about dnsmasq a lot at last week&#39;s talk at ripe.<br>
<br>(this talk was the first time anyone had ever asked me to talk about the good stuff happening from the cerowrt development/user/open source model and process, rather than about bufferbloat. It was kind of neat. But then I only had 20 minutes and ended flat... It was my last talk of the &quot;fq_codel world tour&quot;. I return to the USA next week and plan to spend quite a while in california.<br>
<br>if you are not as tired of me as I am, all the talks are linked to off of:<br><br><a href="http://www.bufferbloat.net/projects/cerowrt/wiki/Bloat-videos">http://www.bufferbloat.net/projects/cerowrt/wiki/Bloat-videos</a><br>
<br>)<br><br>As a result of the tour... and having a chance to play a little guitar here and there...<br><br>I am thinking of getting some t-shirts designed. Actually, as I figure most people here already have a closet full of industry t-shirts, perhaps some socks is more appro - symbolically for the fleet of foot! or (practically) for those that have lost half their existing socks somewhere in europe... Anyone have some good ideas as to a logo/design/sayings to put on socks? Please start riffing...<br>
<br>the only idea I have t-shirt-tour-wise is this:<br><br><a href="http://www.deth.com/images/Iband-back.jpg">http://www.deth.com/images/Iband-back.jpg</a><br><br>&quot;We Beat the Bloat&quot; - available in size XL, maybe?<br>
<br>anyway getting back to cerowrt plans...<br><br>I would like to fold in the &quot;best of&quot; the homenet and hipnet work...<br><br>I also plan to incorporate the now famous ietf demo as a package you can run to demonstrate the effects of bufferbloat.<br>
<br>As always suggestions wanted, and patches gladly accepted.<br><br>Given the severity of the crash bug right now I don&#39;t know when this will become a stable release series, but as it had been a while since putting out a new one, nor had I communicated the feature creep, well, here you go...<br>
