[LARTC] RTNETLINK answers: Invalid argument, fwmark

[David Watson]

	I'm using htb classes on my firewall to queue traffic and implement 
different restrictions on different protocols.

tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 190
tc class add dev eth0 parent 1: classid 1:3 htb rate 2mbit burst 30k
tc class add dev eth0 parent 1:1 classid 1:90 htb rate 50kbit ceil 384kbit 
burst 5k
tc qdisc add dev eth0 parent 1:90 handle 190: sfq perturb 10
tc qdisc add dev eth0 parent 1:3 handle 310: sfq perturb 10


tc filter add dev eth0 protocol ip parent 1:0 prio 1 handle 3 fw flowid 1:3

This last line gets a "RTNETLINK answers: Invalid argument"

I'm using kernel 2.4.18 with the htb and wrr patches on both the kernel and 
on tc
in the kernel .config I have:

CONFIG_IP_ADVANCED_ROUTER=y
CONFIG_IP_MULTIPLE_TABLES=y
CONFIG_IP_ROUTE_FWMARK=y


	I'm not really sure where else I could be going wrong, any advice would be 
greatly appreciated.

You attach class 1:90 to class 1:1, but you didn't create class 1:1 ??

         I missed a line in my report and I do in fact create a 1:1 class 
before attaching to it. I have found that if I change the prio value on the 
filter lines to unique numbers that I no longer get the error. I am however 
confused as to the meaning of the prio parameter, and I'm not sure why 
these filter lines need unique values or exactly what impact these values have.
