Description Numan Siddique 2022-05-04 15:14:33 UTC 
Description of problem:

ovs-vswitchd is evicting and re-adding the IPv6 related datapath flows whenever revalidation is triggered.



Version-Release number of selected component (if applicable):


How reproducible:
All the time.


Steps to Reproduce:

# Reproducer script

Start openvswitch


--------------------------------------

# Program the below flows in br-int

cat << EOF > flows.txt
table=0, priority=120 ipv6,icmp6,nw_ttl=255,icmp_type=135,icmp_code=0,nd_target=1000::10 actions=NORMAL
table=0, priority=0 actions=NORMAL
EOF

ovs-vsctl del-br br-int || :
ovs-vsctl add-br br-int
ovs-ofctl add-flows br-int flows.txt

create_fake_vm() {
    iface_id=$1
    name=$2
    mac=$3
    ip=$4
    mask=$5
    gw=$6
    ipv6_addr=$7
    ipv6_gw=$8
    ip netns add $name
    ovs-vsctl       -- add-port br-int $name       -- set interface $name type=internal       -- set Interface $name external_ids:iface-id=$iface_id
    ip link set $name netns $name
    ip netns exec $name ip link set lo up
    [ -n "$mac" ] && ip netns exec $name ip link set $name address $mac
    ip netns exec $name ip addr add $ip/$mask dev $name
    ip netns exec $name ip addr add $ipv6_addr dev $name
    ip netns exec $name ip link set $name up
    ip netns exec $name ip route add default via $gw dev $name
    ip netns exec $name ip -6 route add default via $ipv6_gw dev $name
}

ip netns delete p1 || :
ip netns delete p2 || :

# Create namespaces for p1 and p2 fake VMs.
create_fake_vm sw0-port1 p1 50:54:00:00:00:03 10.0.0.3 24 10.0.0.1 1000::3/64 1000::1
create_fake_vm sw0-port2 p2 50:54:00:00:00:04 10.0.0.4 24 10.0.0.1 1000::4/64 1000::1

# Start nc server on p1
# ip netns exec p1 nc -l -k -v 1000::3 8080

# Connect to the server from p2
# ip netns exec p2 nc 1000::3 8080

# In a separate terminal, trigger re validation

cat << EOF > trigger_dp_issue.sh
#!/bin/bash

ovs-vsctl --may-exist add-br brtmp

while true
do
    ovs-ofctl add-flow brtmp "table=0,priority=100,ip,udp actions=NORMAL"
    sleep 5
    ovs-ofctl del-flows brtmp
done

EOF

chmod 0755 trigger_dp_issue.sh

# On another session monitor datapath flows.

cat << EOF > monitor_dp_flows.sh
#!/bin/bash

watch -n1 "ovs-dpctl dump-flows -m"
EOF

chmod 0755 monitor_dp_flows.sh

--------------------------------------

Keep sending the traffic from p1 and p2.  And you'd notice that the datapath flows gets evicted and re-added with the same match.

This results in performance issues as there will be an upcall whenever revalidation threads kick-in.
