Hi I'm doing traffic shaping with tc on '10.0.0.0/30' and '10.0.0.28/30'. I want to delete part of shaping rules on the fly. (see my configuration at the end of this mail) I wan't to delete the shaping for '10.0.0.0/30' on the fly while still keeping the shaping for part '10.0.0.28/30' running. When I for example delete rules beginning with the last added rules - I get an error when deleting the rule for 'class': [root@malinko shape_www-0.20]# tc filter del dev eth0 protocol ip prio 5 parent 2:22 u32 ht 104:3: match ip dst 10.0.0.3 flowid 2:1012 [root@malinko shape_www-0.20]# tc qdisc del dev eth0 parent 2:1012 handle 1012: sfq perturb 4 [root@malinko shape_www-0.20]# tc class del dev eth0 parent 2:22 classid 2:1012 htb rate 128kbit ceil 128kbit burst 0 cburst 0 RTNETLINK answers: Device or resource busy If I try to delete the whole part of 'handle 104': [root@malinko shape_www-0.20]# tc filter del dev eth0 protocol ip prio 5 parent 2: u32 match ip dst 10.0.0.0/30 hashkey mask 0x000000ff at 16 link 104: [root@malinko shape_www-0.20]# tc filter del dev eth0 parent 2:22 handle 104: protocol ip prio 5 u32 divisor 256 Here there is no error but all filter rules is deleted also filter rules for '10.0.0.0/30' and a have no shaping at all. Are there known bugs when deleting with tc? Is there some way to do this?
