Hi everyone,

I stumbled by chance in a deadlock condition using HTB and the ingress scheduler at the same time.

- The bug seems to have been introduced in 2.6.23 and forward ( 2.6.22 works fine )
- Tested up to 2.6.25-rc8

I found a temporary workaround ( the ingress didnt have a reason to be there in first place , just omitting it from the script avoids the condition ), but it would be nice to have a proper fix. Let me know if more data/testing is needed.

- Enrico

Server Configuration:
---------------------

Centos 4.6 , DELL R200
Vanilla SMP Kernel 2.6.25-rc8 ( see below for configuration )

Network configuration:
-----------------------

eth0 - Simulated WAN ( 192.168.1.8/24 )
eth1 - LAN ( 10.2.0.1/16 )

Crasher script
------------------------

#!/bin/sh
#set -x
iptables -F -t filter
iptables -F -t mangle
iptables -F -t nat
iptables -X -t filter
iptables -X -t mangle
iptables -X -t nat
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT

# enable forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
# enable nat from 10.2.0.0/16
iptables -t nat -I POSTROUTING -o eth0 -s 10.2.0.0/16 -j MASQUERADE
# init htb
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb

tc qdisc add dev eth0 ingress
#-----------
while true ; do
tc filter del dev eth0 parent 1:0 protocol ip prio 2
tc class del dev eth0 classid 1:1000
# crash happens here, kernel stuck in the previous tc command
tc class add dev eth0 parent 1:301 classid 1:1000 htb rate 1000kbit ceil 1000kbit prio 1 quantum 1514
tc filter add dev eth0 parent 1:0 protocol ip prio 2 handle 0x1000 fw flowid 1:1000
iptables -t mangle -I FORWARD -o eth0 --source 10.2.0.0/16 -j MARK --set-mark 0x1000
echo -e ".\c"
sleep 1
done

How to test
-----------

On a client connected to the LAN , with 10.2.0.1 as a gateway, start an iperf session as follow ( an iperf -s is running on the host 192.168.1.1 )

iperf -c 192.168.1.1 -t 2000 -i 1

On the server, run the crasher script as the client continues running the iperf test the server should freeze almost instantly. After a while the console spits out the following:

I can't figure out the problem. Could you retry using this patch? It should hopefully show us on which class qdisc_decrease_qlen is looping.

Hi everyone,
I stumbled by chance in a deadlock condition using HTB and the ingress scheduler at the same time.

Quoted 8 lines

- The bug seems to have been introduced in 2.6.23 and forward ( 2.6.22 works fine )
- Tested up to 2.6.25-rc8
I found a temporary workaround ( the ingress didnt have a reason to be there in first place , just omitting it from the script avoids the condition ), but it would be nice to have a proper fix. Let me know if more data/testing is needed.

Hi,

It's a very nice test and results, but alas I don't have 3 boxes around, so I wonder if you could try this debugging patch below?

I think one of possible reasons could be a qdisc with the same handle and parent ids, like ingress, but I can't see how it could be referenced by your htb classes yet...

Thanks,
Jarek P.

[NET_SCHED] sch_api: fix qdisc_tree_decrease_qlen() loop

TC_H_MAJ(parentid) for root classes is the same as for ingress, and if ingress qdisc is created qdisc_lookup() returns its pointer (without ingress NULL is returned). After this all qdisc_lookups give the same, and we get endless loop. (I don't know how this could hide for so long - it should trigger with every leaf class deleted if it's qdisc isn't empty.)

After this fix qdisc_lookup() is omitted both for ingress and root parents, but looking for root is only wasting a little time here... Many thanks to Enrico Demarin for finding a test for catching this bug, which probably bothered quite a lot of admins.

I don't think we should do that, it would be preferable to compare the entire handle instead of just the major to avoid this.

On second thought I agree with you, the behaviour is inconsistent and FFFF: shouldn't be used as major, otherwise the major doesn't uniquely identify a qdisc anymore.

I don't think we should do that, it would be preferable to compare the entire handle instead of just the major to avoid this.
Probably you are right... I guess you could handle this?
On second thought I agree with you, the behaviour is inconsistent and FFFF: shouldn't be used as major, otherwise the major doesn't uniquely identify a qdisc anymore.

That patch shouldn't have been there, please ignore :)

Like ingress vs. root handle? I think it's more about additional checks (and good memory).

...and here WARN_ON() instead of if (): root is never looked up, so we can't get NULL nor ingress here; if we have non-ingress ffff:0000 we'll get it (and ingress can't co-exist).
