There is currently no support for the multicast/broadcast aspects
of VXLAN in ovs. In the datapath flow the tun_dst must specific.
But in the IP_TUNNEL_INFO_BRIDGE mode the tun_dst can not be specific.
And the packet can forward through the fdb table of vxlan devcice. In
this mode
Hello OVS team,
I have a ovs-vswitched crash of ovs version 2.8.2. I don't have the flow
which has lead to this crash, but from the backtrace I could see that the
crash is because of double locking. The ofproto_mutex lock is acquired in
handle_packet_out() and the same lock is being tried to

Really? Huh, well now I suspect I did something wrong. Let me recheck

If there is low maximum connection count configuration and less than 10
connections in a bucket, the calculation of the maximum number of
connections to clean for the bucket could be zero, leading to these
connections not being cleaned until and if the connection count in the
bucket increases.
Looks good to me Lorenzo.

Previous commit added a new OVS action 'check_pkt_larger'. This
patch supports that action in OVN. The syntax to use this would be
reg0[0] = check_pkt_larger(LEN)
Upcoming commit will make use of this action in ovn-northd and
will generate an ICMPv4 packet if the packet
From: Numan Siddique
This patch adds 2 stages in router pipeline after ARP_RESOLVE
and adds the logical flows to check the packet length and
generate ICMPv4 packet.
* S_ROUTER_IN_CHK_PKT_LEN - Which checks the packet length using
check_pkt_larger OVN action
From: Numan Siddique
This action is similar to the existing 'icmp4' OVN action except that
that this action is expected to be used to generate an ICMPv4 packet
in response to an error in original IP packet. When this action
injects the icmpv4 packet, it also copies the original IP datagram
From: Numan Siddique
In order to support OVN specific fields (which are not yet
supported in OpenvSwitch to set or modify values) a generic
OVN field support is added in this patch. These OVN fields
gets translated to controller actions.
This patch adds only one field for now - icmp4.frag_mtu.
From: Numan Siddique
This patch adds a new action 'check_pkt_larger' which checks if the
packet is larger than the given size and stores the result in the
destination register.
Usage: check_pkt_larger(len)->REGISTER
Eg. match=...,actions=check_pkt_larger(1442)->NXM_NX_REG0[0],next;

From: Numan Siddique
This is an RFC series to address the MTU issues for OVN reported
here [1].
To address this issue, a new OVS action - check_pkt_larger is added.
A new datapath action is also added - check_pkt_len.

Hi.
I made few tests on PVP with bonded PHY setup and found no significant
difference in maximum performance with low and medium number of flows
(8 - 8192). In case of big number of flows (64K - 256K) I see performance
drop in about 2-3%. I think that because of prefetching of a second cacheline,

Thanks for your contribution.

Add the possibility to configure a static IPv4 and/or IPv6 address
and get MAC address dynamically allocated. This can be done using the
following commands:
$ovn-nbctl ls-add sw0
$ovn-nbctl set Logical-Switch sw0 other_config:subnet=192.168.0.0/24
$ovn-nbctl set Logical-switch sw0

if pre_count less than 10 and n_conn_limit less than CONNTRACK_BUCKETS * 10,
the limit for sweep_bucket will be 0, so the expired connections in bucket can
not be clean.
set the minimum limit to 10.
