Well, I have never before seen such a clear explanation of router
firmware configuration. I had expected the script to be launched from
rc, not rc.local. The latter, however, might be regarded as good
practice, and, if rc is derived unchanged from OpenWrt, might make code
maintenance much easier.
I reinstated the script in rc.local to launch /etc/fixdaemons,
overwritten as you say by the /overlay/etc/rc.local I had introduced,
and all wireless connected machines have reacquired ipv4 DHCP addresses,
in addition to the ipv6 addresses they possessed.
Thank you.

The actual CeroWRT is a RO filesystem, with modifications stored in an
overlay. you can see the original file with no customizations in /rom.
/overlay is mounted "over" the ROM. If nothing has been changed the
/rom file is read, if you have made a change, then it's read from the
overlay. A change that you can make is deleting a file that exists on
the /rom image, and that can be stored on the overlay as well (the
file will be not be visible in the merged /). You can purge changes
that you have made by removing the corresponding file(s) and/or
directory(s) in the /overlay filesystem.

What do you mean by 'overlay/etc/rc.local'?
I have used 2 backup configurations, one with iptables rules in
rc.local, and one with no uncommented text, other than 'exit 0'.
Both show the same problem.
I have previously operated this Mac with a wired connection. I was
thinking this was a 10.8.5 problem prior to your comment.

I have a laptop running 10.8.5 that's working. I had to remove
the /overlay/etc/rc.local file and reboot before Dave's
/etc/fixdaemons would show up. My saved configuration was
stopping it from working.

The simple expedient of putting a script in /etc/rc.local
to restart
pimd, minissdpd, and dnsmasq 60 seconds after boot
appears to get us a
working dhcp/dns on the wifi interfaces once again.
dnsmasq wasn't busted, it was how it interfaces to
netifd. the march
down to something deployable resumes with rc4.
This is the first test that I know of, of some of the RNG
fixes
upstream, notably the mips code does the right thing with
a highly
optimized "get_cycles()".
There are two changes to the firewall code
1) There has been a long-standing error in not blocking
port 161
(snmp) from the outside world. It is now blocked by default.
Although I am not aware of any exploits of this (besides the
information leakage) I would recommend blocking this port
by default
on your existing builds, also, or disabling the snmp
daemon entirely
if you do not use it.
2) Usage of the "pattern matching syntax" on various
firewall rules.
Instead of 3 rules for se00,sw00,sw10, and 4 for
gw00,gw10,gw01,gw11
there are now 1 rule for s+ and one rule for gw+
This does not show up in the web interface correctly. I'd
also like to
get to a more efficient rule set for the blocked ports,
perhaps with
ipset...
...
It's sort of my hope that with these fixes that the march
towards a
stable release can resume, and we get some fresh shiny
new bugs out of
this.
Upcoming next are a revised version of pie, more random
number fixes,
and I forget what else.
