So I've been trying to use unofficial firmware images from this site for my Linksys E4200v2 router. One of the reasons I wanted to try it was SQM - I've found our connection can have large latency spikes and can be unusable while someone else is doing streaming or such. SQM seemed like an all-in-one solution, superior to any manual QoS scheme I could manage.

The build posted on the page had bizarre issues where it wouldn't let me install any software - the LuCI modules worked, but anything behind them simply didn't. I tried changing to the Release Candidate repos, but no joy. I ended up compiling it myself and making a clean install - it had a bizarre issue where it didn't want to start the 2.4 GHz wifi, which seemed to go away after turning on the 5 GHz antenna and rebooting once or twice.

Using the RC3 repos in my new build, miniDLNA installed and worked just fine, so I thought that it would be just the same for sqm-scripts. Well, the result is...not so much. I can't exactly give you all the errors (I didn't log it all and I've got a headache now and am probably going to go rest), but here's what I got from PuTTY during the session I gathered samples for:

I know it's probably partially due to the use of an unofficial build, but that compiles straight from the same code that an official image would, just slightly patched and repackaged. Does anyone have insight on any of this?

I believe openwrt uses signed packages now, so you probably should not only build the core firmware yourself, but also include all packages directly into the build. If I recall correctly that way the package can be preinstalled in the firmware image and hence should never be a mismatch for the rest of the built. BUT sqm-scripts is a bit of a moving target and you probably should try a more recent version from its own repository (https://github.com/tohojo/sqm-scripts), as the latest changes have not yet made it into the openwrt repositories.

My hunch is that is caused by sqm-scripts requiring certain kernel modules and the installer seems to check the actual kernel version for those modules, and if they do not match the installed kernel it does not work. But I am quite uncertain about that, as I have never build openwrt myself so the above could be the finest Baloney...

Is this from before the switch to musl? Or more precisely, are you using ulibc or musl as the c library of your build? I ask because yesterday we fixed an issue with musl and regexp patterns that have at least some symptoms similar to yours.

Woha, these last two lines do not look great, I wonder whether you have the full ip and tc packages installed?

Not sure where or what gets dumped here, but it might be interesting to look at the dumped data, no?

And this looks like a lot of modules required for sqm-scripts tp its thing are missing? Unless you selected y for all of them during your openwrt configuration instead of m. Without (most) of those modules (either as modular modules or as built-in "modules") sqm scripts is not going t work at all, sorry. The newer code learned to test some functionality and stopping on error instead of trying to just push through as the old code did, but that will just give you slightly more diagnostics...

I have to agree this is sqm-scripts not finding the environment it needs, and then not behaving helpfully but just getting confused. I hope that we improved that behavior a bit with the newer sqm revisions. If you could try to manually update all sqm related files in your firmware it would be interesting to see how helpful the new code will be.

If you should be inclined to try this out here are a few pointers on how to proceed (you probably know this already:

Okay, for doing it manually I the easiest would be to clone the following git repository:
https://github.com/tohojo/sqm-scripts
from a unix machine/VM and then run:
make install PLATFORM=openwrt DESTDIR=./owrt_1.0.2 from the root directory of that cloned repository
which will create a directory structure under ./owrt_1.0.2 containing all the files that you need to copy onto the corresponding directories on your router.

This will not fix any of your real issues, but might give better diagnostics and potentially allows us to improve the diagnostic messages even more .

Best Regards
M.

As far as I understand, QueenFiona is using the Chaos Calmer 15.05 branch (based on reference to "RC3"), which is not using musl unless specifically told so. (It is currently confusing as Chaos Calmer references both the to-be-released Chaos Calmer with uClibc as the default and to the ongoing trunk development with musl.)

The for-15.05 branch still uses pre-1.0 sqm-scripts sources at the Openwrt github packages:
https://github.com/openwrt/packages/commits/for-15.05/net/sqm-scripts
while trunk has moved to sqm-scripts 1.0.2 at Toke's repo.

Have you installed kmod packages with opkg --force ?
Try a new build without sqm-sript from CC-Branch but select kmod packages
or delete feeds/package/net/{sqm-srcript,luci-app-sqm} and copy sqm-script from trunk package feed to CC its include the luci-app-sqm.

This packages a needed for sqm to work:
PACKAGE_kmod-sched
PACKAGE_kmod-ifb
PACKAGE_ip
PACKAGE_tc
PACKAGE_iptables-mod-ipopt
PACKAGE_iptables-mod-conntrack-extra

Flash your new image without keep config then im 99% am sure sqm work now.

EDIT:
Candyhouse patch is hacky work good i think if you only use the build system to install new packages dont use opkg to install packages from openwrt repository. They a not compatible. sqm-sripts is ok its not a binary.

here look thats why:
-CONFIG_TARGET_OPTIMIZATION="-Os -pipe -mno-branch-likely -mips32r2 -mtune=34kc"
+CONFIG_TARGET_OPTIMIZATION="-Os -pipe -march=armv5te -mtune=xscale"

-CONFIG_TARGET_SUFFIX="uclibc"
+CONFIG_TARGET_SUFFIX="uclibcgnueabi"

EDIT2: oh that can not work it used a kernel outside from openwrt i make a patch

EDIT3: del patch was wrong

Well, at the very least, I can tell you that I do indeed have all the packages listed in trismo's post installed, according to LuCI. I'm just using the build that the Candyhouse Makefile pulls, which comes from git://git.openwrt.org/15.05/openwrt.git, so I'm not sure if that's the RC or the branch. At the very least, the packages that are supposed to be there are there, or at least LuCI thinks they are.

So, I have never build my own firmware image and hence will be only of limited help, I do have some experience with sqm though, so should be able help debug that part of the problem a bit.
That said, from your initial post it looks like a number of essential modules are missing. Could you post the output of the following command, run on your router's copmmand line, please? This should shpow which modules are available.

ls /lib/modules/$( uname -r)

also please post the output of the following command (which should show the already loaded modules):

lsmod

Thank you very much in advance.

Hi Queen Fiona,

I agree with trismo, your kernel is lacking quite a number gf modules that are essential for sqm-scripts. What about having a look at https://forum.openwrt.org/viewtopic.php?id=50914 and using his config as basis for your own built? I would hope that arokh's configs should be configured for working sqm-scripts and they even offer the cake qdisc, all you probably need to do is making sure your specific router model and its hardware drivers are configured in...

Best Regards
M.

Here i built a kernel for you i hope its run :-)

md5sum 73744f60558b019f2ec851fe45be00fe uImage-3.19.5-ea4500

how i make it

Install a Linux Distribution you need installed tools "git make binutils gcc-arm-none-eabi u-boot-tools"

git clone https://github.com/cilynx/Candyhouse-Linux.git
cd Candyhouse-Linux
$make usb
$cd linux-*
$make menuconfig ARCH=arm
$make oldconfig ARCH=arm
$make -j4 ARCH=arm LOADADDR=0x00008000 uImage
$make ARCH=arm dtbs
$cd ..
$cat linux-3.19.5/arch/arm/boot/zImage linux-3.19.5/arch/arm/boot/dts/kirkwood-candyhouse.dtb > /tmp/zImage+kirkwood-candyhouse.dtb
$mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n linux-3.19.5 -d /tmp/zImage+kirkwood-candyhouse.dtb uImage-3.19.5-ea4500

The discussion might have continued from here.
