This is the third of a string of mails discussing what can be dropped
from cerowrt rc8.
IPv6 is always a headache. Universally, feedback on the 6to4 scheme we
have in place has been negative. It works well in places where
6to4 works, and not at all where 6to4 doesn't work, and creates
complications in the firewall rules and doubles the amount of
testing we should theoretically be doing against all forms of
networking, notably TCP.
The only portion of the ipv6 support that anyone with funding has
expressed an interest in has been DHCP-PD, and expending
resources to make that work well, may well be a good idea.
That said, we've found and helped fix plenty of bugs in ipv6, and
going DHCP-PD only makes it impossible for anyone not
in a DHCP-PD environement to accomplish anything with ipv6, and most
early deployments are only giving out a /64 which
is useless for doing anything with the current, multiply routed
architecture of cerowrt. If we kept AHCP we could leverage
that + DHCP-PD.
I am not able to test ipv6 at all, in paris, at present. It is
completely blocked everywhere I have been in Paris.
Eliminating IPv6 entirely from our test cycles and build process would
save a lot of time.
This gets bugs #98, #140, #145, #239, #273, and to some extent #311
and a few others off our plate in the next quarter.
