[Cerowrt-devel] Latest IPv6 Updates

[Cerowrt-devel] Latest IPv6 Updates

[Steven Barth]

Hi guys,

the following updates / changes for IPv6 have been commited to OpenWrt 
in the last days. Most of these affect RFC 6204 CE-compliance, some are 
convenience changes.

Feel free to merge and test CeroWrt.

* Detect and delegate IPv6-specific MTU from upstream interfaces (e.g. 
tunnels, pppoe, etc.) and propagate them to downstream interfaces 
(supporting cases where IPv4-MTU and IPv6-MTU differ, e.g. 6in4, 6rd, 
6to4, ...)

* Add a default null-route for delegated prefixes (CE-requirement WPD-6)
This fixes routing loops in case packets with a destination within an 
unused / unassigned part of a delegated prefix are received.

* Added support for site-borders (interfaces which ULA-traffic might not 
cross) as specified in CE-requirement ULA-4

* Added support to override CE-requirement ULA-5 for NPT-setups (iirc 
not relevant if dnsmasq is used, as it does not follow ULA-5).


Documentation on http://wiki.openwrt.org/doc/uci/network6 has been updated.



Btw. Simon Kelley released 2.66-test4 which fixes some bugs related to 
stateful DHCPv6 and should make it usable finally. Also the new 
MTU-propagation mentioned above is now supported by dnsmasq as well.
I haven't tested it myself yet but you can try if you are brave.


I will try to make a table about the RFC requirements for Customer Edge 
(CE)-Routers soon which sums up which requirements are fulfilled and 
which are still not implemented both for CeroWrt / OpenWrt with 6relayd 
and with dnsmasq as RA/DHCPv6-server.


Cheers,

Steven

I have merged with openwrt head, and updated to dnsmasq 2.66test4, and
also folded in the tiny luci upnp fix to the '&' issue. I'm not really
sure if that last is the right thing, it's supposed to be
translated...

http://snapon.lab.bufferbloat.net/~cero2/cerowrt/wndr/3.6.11-4/

I am still not in a position to test anything cerowrt related myself
right now, although I am down to a mere 20 miles between me and the
yurtlab and 50 from isc.

I am relieved to hear that amazon claims they will get new supplies of
the wndr3800 by jan 5.

I am staring at the bunch of hardware I ordered in something of a
panic - dreamplug, wndr4300, the nanostations, a couple bus pirates, a
nexus 7, and trying to figure out a direction to move forward that
makes sense.

Excellent! PPPoE?

I folded in the same patches as were used in 2.66-test3.

A good default configuration for cero would be good, Not sure what that is...

Upnp works fine.
Ssdpd doesn't, not sure why, it's late now. will test tomorrow.

p.s. /use/shin/simple_qos fails on non-existant /etc/functions.sh
Am I doing something wrong?

No. Probably that changed. You can comment that out. I see also that
nfq_codel on the nano-m build failed to link right. Might just be a
bug on that build. insmod sch_nfq_codel on cero.

Thanks for mergin upnp/ssdpd stuff!

Upnp works fine.
Ssdpd doesn't, not sure why, it's late now. will test tomorrow.

p.s. /use/shin/simple_qos fails on non-existant /etc/functions.sh
