Do I detect a plainative note? I share it...
I'm not aware of any problems on 2.4ghz in the last specific release I
did for comcast. It's been in day-to-day use here since I put it out.
Feel free to give it a shot. The stuff that made it comcast specific
(co-existence with HE tunnels) is solved, so the next gen will be
I AM painfully aware that ht40+ at 5ghz appears to have broken on
several channels (Seems to work on 36 and fail on 44) There was a
fresh merge from wireless-testing recently, that I hope fixes it.
I DO plan a stable release this month if possible, and at the very
least a code freeze fairly soon.
in cerowrt head are fixes for ipv6 tunnel co-existence, mostly
everything now using procd, fixed upnp support (think that landed in
the release above), cleanups of the SQM code for eventual submittal to
mainline landed also.
*Please note* that a source of hangs in the last several cero releases
was an oopsy in turning off logging for ahcp and babeld, which filled
up available memory rapidly. EVERYBODY: Do turn send those logs to
/dev/null if you haven't already in the relevant /etc/config/ files
and look for other sources of memory growth from logs.
the remaining problems are:
got competing work requirements terribly pressing, final pie release
needs to be added, (kind of wanted sch_fq and the other new qdisc from
3.13, too) a bunch of ietf drafts are in the nascent stage and stuck
there, a build server crashed and a whole string of openwrt builds
failed to build, still need /etc/init.d/babeld support for source
specific routing and babel to run out of procd, package signing is
broken, and worst of the cerowrt build broke last week due to some
changes in the openwrt build process I still don't understand.
There is still one unaligned_instruction trap left to beat that
appears to be triggered by odhcpd.

One of the things that scares me is that a bunch of openwrt targets
are migrating to 3.13 and if I miss a window the very stable 3.10.28
release is going to get replaced upstream with 3.13 and resultant
headaches. (and benefits)
As my own deadlines slip everywhere, I made a big push earlier this
week to appeal to many folk to get dnsmasq + dnssec more widely tested
on other platforms in the hope that whenever I got unburied it would
be stable enough to toss into cero. (that's going along swimmingly on
x86 and arm so far)
I hope to replace the failed server this tonight and burn sunday on
trying to resolve the problems above. The currently borked srcs are on
