[Cerowrt-devel] 3.3rc5-1 is out

[Dave Taht]

Dibbler-client is on by default in this build.

I would be very interested to know if dibbler's pd support actually
works in a real environment, (the bugfix for the interface crash *did
work for me* in testing distributing /64s and /56s)

...and if the new 100% of cpu bug (which only seems to happen the
absence of a dhcp v6 server) can be reproduced.
(I'd not seen it before because I'd always HAD a dhcpv6 server present
when playing with dhcpv6)

I note - at least at the moment - anyone trying 3.3rc5-1 without a
dhcpv6 server present, should disable dibbler entirely.

As things turn out...

Tomas updated dibbler to 0.8.2 on me yesterday, incorporating the git
patches I was testing and had proven to work, and tells me it compiles
down much smaller with -Os than it used to. So I imagine that pushing
that up to openwrt head is a good idea.

The new syntax for restricting what interfaces get ipv6 addresses from
dhcpv6-pd is:

downlink-prefix-ifaces "se00" , "eth0", "wlan0", "etc"
