[Cerowrt-devel] Any chance for the LUCI GUI for cake appearing?

It turns out that I am pulling from openwrt for luci-app-sqm, not
ceropackages, and overriding it was a headache. Fixed now, see below

router# cd /tmp; wget
http://snapon.lab.bufferbloat.net/~cero3/luci-app-sqm_3-5_all.ipk ;
opkg install ./luci-app-sqm_3-5_all.ipk
router # /etc/init.d/uhttpd restart

if it breaks, you get to keep both pieces, but it worked for me, and
yea! cake in the gui! thx sebastian!

I tried -

./scripts feeds uninstall luci-app-sqm; ./scripts feeds install -p
cero luci-app-sqm # seemed sane, did not work
git rm in the feed itself did not work
doing the uninstall, deleting the symlink, and the git rm, nuking the
and doing a complete rebuild... eventually did work... but strikes me
as a bit more brute force than I wanted.

I am not in a position (aformentioned build is my specialized for
pico/nano build at the moment) to update the packages db,
but I stuck up the correct new package... which you can install via

Apologies for the confusion, I simply figured that the -p option would
work, and never checked.

I also note that I think I am building things compile tuned for the
archer mips34c, rather thanthe wndr3800´s 24c. However I kept the
unaligned access hacks (not needed on the 34c derived archer, but
needed on the 24c wndr3800)


maintaining 3 separate trees for the platforms we sort of support is a
PITA. Then adding in something that can mesh by default on 2 others.
and then trying to get anything to compile for another arch entirely
and failing...

So if the machine has the cake module and a sufficiently recent (out-of-tree) tc binary installed it should just work. Using the “Advanced option strings…” it even should be possible to pass arbitrary strings to cake (without any error checking), so I assume we are all set up for cake testing (or should that be cake tasting?) from the LUCI GUI. But I have not managed to build cake locally, nor have I dared to risk my families internet connectivity by trying one of Dave’s newer "openwrt trunk with cake” builds. So these changes linger in the ceropackages-3.10 repository until we get enough tasting to convince Toke to pull them into the openwrt repositories (these changes affect both sqm-scripts and luci-app-sqm). Dave graciously allowed me access to one of his test machines, and the changes allow to set up cake from the GUI, but I only did limited functionality testing. (And we discovered that something was of in that cake worked but did not accept all the keywords it should have, but unless you are on a XDSL-Link you most likely do not care about specifying per-packet-overhead)
