[LARTC] Some good news - Strange behavior deleting filters

[LARTC] Some good news - Strange behavior deleting filters

[Andre Correa]

Hi list,

I've got a private e-mail from O. Brewer pointing something important 
that we hadn't figured out yet:

tc qdisc del dev eth1 root
tc qdisc add dev eth1 root handle 1:0 htb
tc class add dev eth1 parent 1:0 classid 1:1 htb rate 1mbit
tc class add dev eth1 parent 1:0 classid 1:2 htb rate 1mbit
tc filter add dev eth1 parent 1:0 protocol ip prio 1 handle ::10 u32
match ip src 10.10.10.10 classid 1:1
tc filter add dev eth1 parent 1:0 protocol ip prio 1 handle ::11 u32
match ip src 10.10.10.11 classid 1:2


tc -r filter show dev eth1 parent 1:
filter protocol ip pref 1 u32 filter protocol ip pref 1 u32 fh
800:[80000000]  ht divisor 1 filter protocol ip pref 1 u32 fh
800::10[80000010]  order 16 key ht 800 bkt 0 flowid 1:1   match
0a0a0a0a/ffffffff at 12
filter protocol ip pref 1 u32 fh 800::11[80000011]  order 17 key ht 800
bkt 0 flowid 1:2   match 0a0a0a0b/ffffffff at 12

tc filter del dev eth1 parent 1: protocol ip prio 1 handle 800::11 u32

tc -r filter show dev eth1 parent 1:
filter protocol ip pref 1 u32 filter protocol ip pref 1 u32 fh
800:[80000000]  ht divisor 1 filter protocol ip pref 1 u32 fh
800::10[80000010]  order 16 key ht 800 bkt 0 flowid 1:1   match
0a0a0a0a/ffffffff at 12

as we expect...

So we figure out that using handle and u32 in the end of our command 
line works fine. Good... There is still a lot of trouble to figure out 
what is the value of handle XXX::yy when it is a script that manages 
filters, but it is better then nothing...

tks for pointing this out Orlie...

Anybody else replicated the behavior? Does anybody know is tc 
development is taking place?

tks a lot...

Andre
