Qosify: new package for DSCP marking + cake

qosify	2021-11-12-bfc2cafe	

Please try to update the qosify package. A new snapshot build with the latest version just finished.

Is there any guide I can follow to tailor this software to my needs? Thanks in advance.

so on wrt3200acm

/etc/init.d/qosify status shows running

however no process or tc shows qdisc

running qosify on its own

libbpf: map 'config': created successfully, fd=4
libbpf: failed to mkdir /sys/fs/bpf/qosify_data/config: No such file or directory
libbpf: map 'config': failed to auto-pin at '/sys/fs/bpf/qosify_data/config': -2
libbpf: map 'config': failed to create: No such file or directory(-2)
libbpf: failed to load object '/lib/bpf/qosify-bpf.o'
bpf_object__load: No such file or directory

Thanks! Now I really need to get my old test router in service again so I can build and test this.

Why? It should be enough to simply not enable sqm on the same interface. One of the things sqm-scripts has going for it is that it allows multiple instances on different interfaces (which occasionally is actually useful).

Thanks for the hint. That approach makes it really easy to include qosify in a build.

Documenting the steps for others:

  • download the llvm-bpf-13.0.0.tar.xz from your router's target downloads to your buildroot. E.g. https://downloads.openwrt.org/snapshots/targets/ipq806x/generic/llvm-bpf-13.0.0.tar.xz

  • extract the files into the buildroot: tar -xvf llvm-bpf-13.0.0.tar.xz

  • Change toolchain option to use a prebuilt LLVM toolchain, and enable qosify. I only needed to add these two lines into my .config recipe, and all other dependencies got pulled in automatically:

    CONFIG_USE_LLVM_PREBUILT=y
    CONFIG_PACKAGE_qosify=y
    

If you have extracted the LLVM toolchain properly, it will get detected by make menuconfig or defconfig, and the related options get set correctly in .config. If the toolchain is missing, the modified config settings will not show up in .config.

There's nothing in qosify that conflicts with sqm-scripts. I mentioned this only because many people get confused thinking that qosify is an add-on to sqm-scripts and that they need both.

Which OpenWrt version are you using? Does /sys/fs/bpf exist on your device, and what's in it?

master + /sys/fs/bpf exists but nothing under

Ah, sure makes sense then!

Is anything mounted to /sys/fs/bpf? Normally it should be mounted by default. Are you using extroot or anything like that?

yes extroot ...

Has anybody else observed (after ~2 days of uptime) bufferbloat is getting worse? After restart of qosify it came back from B grade to A.

Restart of qosify service helped only partially. I was able from time to time to get A bufferbloat mark. Restart of the router however resulted with stable bufferbloat A grade.

i restart every 24h ... master always has memory leak I find ...

Could could please perform the following test:

  1. start qosify fresh.

  2. immediately run the following command on your routers command line and store the output somewhere:
    tc -s qdisc

  3. let things run until bufferbloat gets worse then do not (yet) restart qosify but run:
    tc -s qdisc
    again

  4. restart qosify and run
    tc -s qdisc
    again

  5. post the output of the three call to tc here in the thread, ideally by following these instructions below:

Please use the "Preformatted text </>" button for logs, scripts, configs and general console output.

Please edit your post accordingly. Thank you! :slight_smile:

The goal is to figure out whether the cake instances my disappear.... (for example if you use pppoe-wan your ISP might initiate PPPoE disconnects after which OpenWrt might tear pppoe-wan down and set it fresh up again, after which cake needs to be re-instantiated). I might be barking up the wrong tree here, but I would be happy if you could run that test even though it likely will not help.

In point 3 you can still use another class to configure the bulk priority?

hi everybody I have configured qosify like this

/etc/config/qosify

Summary

`config defaults
list defaults /etc/qosify/*.conf
option dscp_prio CS5
option dscp_icmp +CS0
option dscp_bulk LE
option dscp_default_udp CS4
option bulk_trigger_timeout 5
option bulk_trigger_pps 100
option prio_max_avg_pkt_len 500

config class bulk
option ingress LE
option egress LE

config class video
option ingress AF41
option egress AF41

config class voice
option ingress CS6
option egress CS6
option bulk_trigger_pps 100
option bulk_trigger_timeout 5
option dscp_bulk CS0

config interface wan
option name wan
option disabled 0
option bandwidth_up 16mbit
option bandwidth_down 56mbit
# defaults:
option ingress 1
option egress 1
option mode diffserv4
option nat 1

option autorate_ingress 1
option ingress_options ""
option egress_options ""
option options "overhead 44"

config device wandev
option disabled 1
option name wan
option bandwidth 100mbit`

I added a script so that it starts automatically when starting the router in

/etc/hotplug.d/iface add file qosify and put this in

Summary

`#!/bin/sh

[ -n "$DEVICE" ] || exit 0
[ "$ACTION" = ifup ] && {
echo y | /etc/init.d/qosify reload | start
logger -t qosify "Reloading qosify due to $ACTION of $INTERFACE ($DEVICE)"
}`

and finally i has add my rules in iptables

like this

Summary

my dslreports is amazing and for first impression for the moment my game and network is very good ..

the other thing happening is the following message
procd: Instance qosify::instance1 s in a crash loop 6 crashes, 0 seconds since last crash

i tried to install the new snapshot and the new qosify package but still the same error

Command failed: Request timed out

any other suggestions?
