Hello.
I’ve been looking for it, but I don’t know what to ask…..
I would like to send a message to the controller even if there is a FlowEntry
That matches every time a packet enters the switch.
To do this, the ovs_dp_process_packet has been added as follows:
If (unlikely(!flow)) {
….
}
If (key->eth.type == 8) {
memset(&upcall_temp, 0, sizeof(upcall_temp));
upcall_temp.cmd = OVS_PACKET_CMD_MISS;
upcall_temp.portid = ovs_vport_find_upcall_portid(p, skb);
upcall_temp.mru = OVS_CB(skb)->mru;
error2 = ovs_dp_upcall(dp, skb, key, &upcall_temp, 0);
if (unlikely(error2))
kfree_skb(skb);
else
consume_skb(skb);
}
ovs_flow_stats_update(flow, key->tp.flags, skb);
…
But the computer stops….
What should I do???
And added interval variables to struct flow_stats. The interval time between
packets was then obtained
>From ops_flow_stats_update as follows:
...
flow->stats_last_writer = cpu;
}
}
stats->interval = jiffies – stats->used;
stats->used = jiffies;
stats->packet_count++;
…
How can you send this to the controller??
I’m sorry to keep asking you this…
OVS is too difiicult. I’m so sorry…
Thank you.
