<div>Hi, I configured <a href="http://he.net">he.net</a> tunnel according to <a href="http://wiki.openwrt.org/doc/uci/network6">http://wiki.openwrt.org/doc/uci/network6</a> and works with latest 3.7.2-4.</div><div> </div><div>
However I don't understand how my client is supposed get an ip6 address. radvd is gone and I don't see anything handing out me an ip6 addr. Who's job is it now then?</div><div> </div><div>Maciej<br><br></div><div class="gmail_quote">

<br>
It seems pretty stable but with the ipv6 churn...<br>
<br>
[insert my std hyperbolic warnings about exposing the release to<br>
default gws in front of spouses or young children]<br>
<br>
features:<br>
<br>
+ dnsmasq 2.66test10<br>
+ merge with openwrt head<br>
+ new unaligned access code from openwrt head (by nbd) and the<br>
remainder of the older unaligned patch set (by robert bradley) ported<br>
to work on top of that<br>
<br>
I have not checked to see if all traps are gone, you can look at that via<br>
files in /sys/debug/kernel/mips/<br>
<br>
- it's mostly the ipv6 related traps I'm concerned about...<br>
<br>
The checksum routine changed and I did check checksums on a variety of<br>
ipv4 ethernet traffic, but not enough to feel assured.<br>
<br>
+ Bug fixed <a href="https://www.bufferbloat.net/issues/418" target="_blank">https://www.bufferbloat.net/issues/418</a><br>
<br>
BUG_ON removed on TFO support in the kernel. TFO works. I tested it by:<br>
<br>
echo 3 > /proc/sys/net/ipv4/tcp_fastopen<br>
editing /etc/init.d/polipo to add support for a boolean useTCPFastOpen parameter<br>
adding that parameter to /etc/config/polipo<br>
testing with the current version of httping<br>
<br>
I will update the init script and config in the next spin.<br>
<br>
...<br>
<br>
The churn in how to setup ipv6 sanely continues. The configuration for<br>
how to do it has changed significantly again and is documented at:<br>
<br>
<a href="http://wiki.openwrt.org/doc/uci/network6" target="_blank">http://wiki.openwrt.org/doc/uci/network6</a><br>
<br>
It's not clear to me to state of the ipv6 dnsmasq integration now.<br>
There is much discussion on the dnsmasq-discuss list as to how to do<br>
prefix-independent configuration as one example.<br>
<br>
as for the ipv6 related changes just now come down from openwrt,<br>
steven barth tells me that:<br>
<br>
"6distributed functionality (prefix delegation) was merged into netifd<br>
for size reasons.<br>
The shell mess which was ipv6-support was abandoned.<br>
<br>
dhcpv6 is now a regular network proto in netifd (which can be added<br>
ontop of other ipv4-wan types or separately for ipv6-only).<br>
<br>
network6 is unnecessary now. 6rd, 6to4 now automatically publish their<br>
prefix. 6in4 adds a new option ip6prefix for adding the routed prefix.<br>
<br>
LANs / WLANs which want a prefix now just add a option ip6assign 64 to<br>
the interface definition.<br>
<br>
See examples in: <a href="http://wiki.openwrt.org/doc/uci/network6" target="_blank">http://wiki.openwrt.org/doc/uci/network6</a><br>
<br>
Prefix Announcement / DHCPv6 / Relaying has been untangled and should<br>
be moved into the respective daemon config / init. I've done this for<br>
6relayd.<br>
<br>
For dnsmasq you will have to add config support similar to what is<br>
done for DHCP in IPv4, so it should be easy to adapt. Maybe some of<br>
the CeroWrt contributors like to add that.<br>
<br>
I also haven't looked at NPT yet. I've removed the shell-script mess<br>
for now as we will not have all targets up to 3.7 in the coming weeks<br>
and therefore also not a new ip6tables."<br>
<br>
AHCP is still lost and lonely in the configuration.<br>
<br>
I took a stab at enabling ipv6 NPT support myself in this release, but<br>
the changes I'd made to the openwrt configuration didn't successfully<br>
get the modules to compile nor create a package. My *non-working<br>
patch* looked like this, and suggestions as to what sort of magic wand<br>
to wave over it welcomed.<br>
