[Cerowrt-devel] cerowrt 3.3.8-1 and related

3.3.8-3 is the first major resync between openwrt head and cerowrt
in nearly a month...

and needed a lot of love just to get that far.

I'm very happy that it's "final" versions of the codel codel and
getting-close-to-openwrt's-freeze versions of openwrt....


Some more polish and testing is needed, so I would be reluctant to
have you just slam it into your default setup.


ethtool's syntax changed on me, so fq_codel is not being enabled
properly on the ethernet interfaces.

The new version of quagga isn't quite baked yet, so babeld is the default still.

There is a bug in the new firewall rules in the last stanza - it
should read "guest" and have a different name than the previous
stanza. I did fix the "lan" rule mentioned in the previous email. Mo
bettah rules desired...

Felix has made some major improvements on the ath9k front, which I
haven't tested against bug #379 and related yet.

I haven't addressed the long-standing upnp issue.

There was a switch to netifd also. My concern here is that ahcpd will break.

gpsd is now from openwrt head, not ceropackages.

dnsmasq isn't fully enabled with ipv6 dhcp support yet.

jabberd is installed on the router with access limited to the ip address
ranges on the secure network (see /etc/xinetd.d/xmpp-client for details)

There are two default jabber users there, with default passwords. I'm
not happy with this setup, but it is kind of neat to be able to leave
notes to the other person's that use the router, on the router....

Transmission (bittorrent) is included but disabled by default. I have
some patches for it for both ipv6 classification and uTP diffserv,
too, that didn't make 3.3.8-3.

And so on. By all means, please test, but my usual concerns about
installing something alpha-quality on your primary gateway to the
universe in the presence of wives, parents, or children, apply.

Jeeze, I have barely had that built for an hour...

Please note that codel is the base substrate for a new class of
network queuing algorithms, of which the first is fq_codel. I would
recommend you run fq_codel in preference to codel in nearly all

I keep trying to make these distinctions clear, because many other
things besides fq_codel are possible on top of codel. I hope others
will clearly distinguish between "codel": the underlying theory and
basic drop strategy, and stuff layered on top of it like fq_codel,
qfq+codel, and stuff like the openwrt qos scripts and the currently
under test simple_qos script. (which use hfsc and htb, respectively,
for soft-rate limiting)

I re-enabled the QoS tab to see how good the std openwrt + fq_codel
implementation now was, so as to compare it against simple_qos, so
you can try either and let us know how it works. :)

The AQM tab remains entirely disfunctional.
