[LARTC] Adding dsmark qdisc fails
Title: Adding dsmark qdisc fails I'm having a problem identical to one encountered on this list awhile back: I'm trying to configure dsmark qdisc on 2.6.11.4 user mode linux and tc from iproute2-2.6.11-050314. I think I have some mismatch in my setup since adding dsmark qdisc fails *unless* I specify "set_tc_index" argument which I believe should be optional: # tc qdisc add dev eth1 handle 1:0 root dsmark indices 8 RTNETLINK answers: Invalid argument Mar 20 13:00:50 user user.debug kernel: dsmark_init(sch a0bb3ae0,[qdisc a0bb3b60],opt ) here the log shows that opt is null, sch_dsmark checks for that and bails out. However running tc with "set_tc_index" goes ok: # tc qdisc add dev eth1 handle 1:0 root dsmark indices 8 set_tc_index Mar 20 13:01:12 user user.debug kernel: dsmark_init(sch a0bb3060,[qdisc a0bb30e0],opt a038e9d0) Mar 20 13:01:12 user user.debug kernel: dsmark_init: qdisc a0bb30e0 # tc qdisc show dev eth1 qdisc dsmark 1: indices 0x0008 set_tc_indexbut then changing the class fails: # tc class change dev eth1 classid 1:1 dsmark mask 0x0 value 0xb8 RTNETLINK answers: Invalid argument Mar 20 13:02:28 user user.debug kernel: dsmark_get(sch a0bb3060,[qdisc a0bb30e0],classid 10001) Mar 20 13:02:28 user user.debug kernel: dsmark_change(sch a0bb3060,[qdisc a0bb30e0],classid 10001,parent 0),arg 0x2 Any ideas where I've gone wrong? -- Tero I've applied the patch to my iproute2 that was suggested as a solution, as well as upgrading to the latest version (http://developer.osdl.org/dev/iproute2/download/iproute2-2.6.14-051107.tar.gz) of iproute2 which includes the patch, but always get the following errors: # tc qdisc add dev eth1 handle 1:0 root dsmark indices 64 RTNETLINK answers: Invalid argument Changing that to: # tc qdisc add dev eth1 handle 1:0 root dsmark indices 64 set_tc_index Works, but following that with produces the same error: # tc class change dev eth1 classid 1:1 dsmark mask 0x3 value 0x88 RTNETLINK answers: Invalid argument Is this an iproute2 bug, or user error?

[LARTC] Wondershaper and DSCP
Did anyone ever answer this one? THIS is what I am trying to do:
[LARTC] cbq+sfq and DSCP marking

Hi,
I am a little confused about traffic control at egress + DSCP marking.
Suppose I have a home router and set three different traffic classes at
the
egress interface in a similar way to what wondershaper (cbq version)
does:
tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 10mbit
tc class add dev $DEV parent 1: classid 1:1 cbq rate ${UPLINK}kbit
allot
1500 prio 5 bounded isolated
tc class add dev $DEV parent 1:1 classid 1:10 cbq rate ${UPLINK}kbit
allot
1600 prio 1 avpkt 1000
tc class add dev $DEV parent 1:1 classid 1:20 cbq rate
$[9*$UPLINK/10]kbit
allot 1600 prio 2 avpkt 1000
tc class add dev $DEV parent 1:1 classid 1:30 cbq rate
$[8*$UPLINK/10]kbit
allot 1600 prio 2 avpkt 1000
tc qdisc add dev $DEV parent 1:10 handle 10: sfq perturb 10
tc qdisc add dev $DEV parent 1:20 handle 20: sfq perturb 10
tc qdisc add dev $DEV parent 1:30 handle 30: sfq perturb 10
Then, I would like to DSCP mark the packets that leave the router based
on
their class. Ex., packets from class 1:10 would be marked with 0xb8 and
packets from class 1:30 would have a 0x0 DSCP mark.
However, after some reading, the only DS marking examples i found was
like
this (i.e., no chance to
add cbq and sfq filters):
tc qdisc add $DEV handle 1:0 root dsmark indices 64
tc class change $DEV classid 1:10 dsmark mask 0x3 value 0xb8
tc class change $DEV classid 1:20 dsmark mask 0x3 value 0x90
tc class change $DEV classid 1:30 dsmark mask 0x3 value 0x0
I am not sure if I understood the dsmark and DSCP marking model. It is
not
posible to add the DSCP marking to the cbq+sfq example above?
Any help would be appreciate. Tnx!
J.
