Hi all
I have panic with kernel 2.6.37-rc6-git2 when use iproute2
mirred/redirect action
host1 (kernel 2.6.36.2)
netperf client -> eth3 (82598EB 10-Gigabit AT CX4) - directly connected
to eth2 of host2
ethtool -k eth3
Offload parameters for eth3:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp-segmentation-offload: on
udp-fragmentation-offload: off
generic-segmentation-offload: on
generic-receive-offload: on
large-receive-offload: off
rx-vlan-offload: off
tx-vlan-offload: off
ntuple-filters: off
receive-hashing: off
ethtool -i eth3
driver: ixgbe
version: 2.0.84-k2
firmware-version: 1.12-2
bus-info: 0000:03:00.1
host2 (kernel-2.6.37-rc6-git2)
netserver -> eth2 (82598EB 10-Gigabit AT CX4) - directly connected to
eth3 of host1
ethtool -k eth2
Offload parameters for eth2:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp-segmentation-offload: on
udp-fragmentation-offload: off
generic-segmentation-offload: on
generic-receive-offload: on
large-receive-offload: off
rx-vlan-offload: on
tx-vlan-offload: on
ntuple-filters: off
receive-hashing: off
ethtool -i eth2
driver: ixgbe
version: 2.0.84-k2
firmware-version: 1.12-2
bus-info: 0000:03:00.0
Normally without ifb and redirect netperf show:
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.0.2
(192.168.0.2) port 0 AF_INET
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
87380 16384 16384 10.00 9042.14
Steps to reproduce panic:
ip link set dev ifb0 up
tc qdisc add dev eth2 ingress
tc filter add dev eth2 parent ffff: protocol ip prio 10 u32 \
match ip src 0.0.0.0/0 flowid 1:1 \
action mirred egress redirect dev ifb0
After this when i start netperf on host1 I have panic (screenshot in
attached image).
Thanks
Pawel
