[LARTC] Can't use fwmark filters

[LARTC] Can't use fwmark filters

[Alex]

Hello,

I'm facing an issue that i have reported on Debian's BTS as a bug against
iproute package. Prior to this i have been looking around trying to find
out what could be wrong but had no success to get it to work.

Below is a what i've reported on Debian's BTS as
http://bugs.debian.org/215629

Here goes the story, thanks for any tip on the subject.

I would like to add a fwmark filter to the original HTB based
LARTC "WonderShaper" script (http://lartc.org/wondershaper/).

I am using a self compiled kernel from latest sarge
kernel-source-2.4.22 and based on kernel-image-2.4.22-k7 provided config
file.

The idea is to add a single additionnal fwmark filter :

tc filter add dev ppp0 parent 1: protocol ip prio 10 \
handle 1 fw classid 1:30

When adding this line i get the following error message :

RTNETLINK answers: Invalid argument

If i modify the WonderShaper script, remove all "tc filter" lines but the
fwmark filter one i get no such error.
The filter seems to get declared just fine.

From here i can start uncommenting some of the "tc filter" lines
provided in WonderShaper without getting any error.
At some point when having enabled again 4 or 5 "tc filter" original
lines the reported error strikes again.

I have tried simplifying the script to something like this :

tc qdisc add dev ppp0 root handle 1: htb default 60

tc class add dev ppp0 parent 1: classid 1:1 htb rate 450kbit
tc class add dev ppp0 parent 1:1 classid 1:10 htb rate 450kbit
tc class add dev ppp0 parent 1:1 classid 1:60 htb rate 450kbit

tc qdisc add dev ppp0 parent 1:10 handle 10: sfq
tc qdisc add dev ppp0 parent 1:60 handle 60: sfq

tc filter add dev ppp0 parent 1: protocol ip prio 1 handle 1 fw classid 1:10
tc filter add dev ppp0 parent 1: protocol ip prio 1 handle 6 fw classid 1:60

Which works fine.

Adding this single line triggers the error again :

tc filter add dev ppp0 parent 1: protocol ip prio 1 u32 \
match ip tos 0x10 0xff  flowid 1:10

---> RTNETLINK answers: Invalid argument


I am stucked here... i haven't been able to find anything related to
this on the net and i hope not to be misusing 'tc'.

Thank you.

Looks like the same problem what i reported ~2 months ago. A quick 
solution would be to use different prio's for fw filters and u32 
filters.
