[Cerowrt-devel] more steps forward

-1) we are working on modernizing, replicating and securing key bits of the
bufferbloat.net infrastructure.

0) I would like to push the sqm scripts and gui up to openwrt-devel
for review soon. It's still missing some things I'd like - inbound
diffserv to BE squashing, support for dynamically setting the target,
a drr emulation of what free.fr does, some stuff I have for emulating
typical dsl and cable modem behavior... and any way of more easily
doing custom prioritizations, but it is what it is, and can be
improved with more eyeballs on it.

1) I am planning to rebase the cerowrt-next tree with a cleaner
patchset, push as much up to openwrt as possible, and put it into
cerowrt-3.10 on github.

Along with that, rename ceropackages-3.3 to ceropackages-3.10.

And retire cerowrt-next entirely. I don't really care much about the
history lost here,
I do care about having a clean patchset.

(this is assuming Barrier Breaker, when frozen in the next quarter or two
 stays on 3.10 for the ar71xx architecture.)

This will become a longer term stable release for us.

Most of that work is done, I'm still sorting through the patchsets on
a couple fronts however, to cut them from, like dozens, to only a few
that make coherent sense.

I hope to get most of that out to openwrt-devel this week.

2) In terms of a shorter term stable release for us, it's evident that
it isn't going to be this month. My cup runneth over.

I MIGHT get something stable enough to use as a test box
after I finish item 1.

3) In sorting through the patchset I found a tiny patch that didn't
make it upstream that is probably responsible for 90% of the new
instruction traps. Not responsible for the older new ones, but right now
I can't even look at the instruction trap problem without crashing the
router, so...

4) Got mosh working today for the first time. It's a cheap hack.

I don't know if anybody else cares
but as for me, I am so frequently blowing up my network and losing
state on a dozen boxes
that it's a relief to be able to cut over to pure mosh everywhere to
survive that.

5) The latest mdnsresponder code landed, and the new hnetd and dns
hybrid proxy code
is being maintained in the homewrt group's repos, which I just added
to cerowrt's feeds.

This is the post-avahi, (probable) post-ahcp future, and it's got lots
of rough edges as yet.

building it as modules now.

6) I have *some* bcp38 code that works, and some ideas as to how to make it
"just work" *mostly* and be on by default, but it lacks uci and gui integration.

Given the marked increase in spoofed udp attacks like the recent ntp exploit,
I'd like to get something that works "out there", but it's clearly a
separate project
that I'd like someone else to "own" and integrate.

7) Still would like to move babeld to run out of procd

8) The remainder of the backlog...
