Hi,
I`ve got problem while queuing with HFSC vlan tagged packets after
migrating my tc scripts from Debian 8.2 (3.16.0-4-amd64) to Debian 9.5
(4.9.0-6-amd64). tc filters added to eth1 do not classify correctly src
and dst ip addresses anymore if they are encapsulated with vlan tag
which wasn`t a problem previously. It works fine if I run them without
vlan tagging oraz if the root device is a vlan (eg. tc filter add dev
eth1.20). Could you please help me find out what has changed in kernel
between those two versions and what is walkaround for that problem?
Example of my classification filters:
tc filter add dev eth1 parent 1:0 prio 4 protocol ip u32
tc filter add dev eth1 parent 1:0 prio 4 handle ${NETWORK_GROUP_HEX}:
protocol ip u32 divisor 256
tc filter add dev eth1 protocol ip parent 1:0 prio 4 u32 ht 800:: match
ip dst ${NETWORK_ADDRESS}/24 hashkey mask 0x000000ff at 16 link
${NETWORK_GROUP_HEX}:
tc filter add dev eth1 parent 1:0 protocol ip prio 4 u32 ht
${NETWORK_GROUP_HEX}:0x${ADDR_Q4_HEX} match ip dst $ADDR classid
1:${MARK_NORMAL}
Best regards
