Yes, that's the branch I meant (I'm starting from it as a place to get
the ddlog code up to speed with OVN master).
That makes sense. Thanks.

I think this is in the ddlog-dev-v2 branch, not master, correct? That branch
was a working directory for me, and I probably just pulled those patches in the
wrong order. Does that make sense?

If a TCP connection is in SYN_SENT state, receiving another SYN packet
would just renew the timeout of that conntrack entry rather than create
a new one. Thus, tcp_conn_update() should return CT_UPDATE_VALID_NEW.
This also fixes regressions of a couple of OVN system tests.

Hi Justin.
In the OVN repo, commit 00523aa8e970 ("tests: Add function to handle
ddlog's id allocation.") adds a stableid utility and uses it in ovn.at.
A few commits later, commit 15e5a8b00cdf ("ovn.at: Break "ovn.at" into
"ovn-components.at" and "ovn-e2e.at".") stops using it and also drops a
Done.

If not supplied by the user --socket-mem and --socket-limit EAL options

numa nodes must be numbered consecutive is removed by this change.
These options can be seen in the ovs-vswitchd.log. For example:

An additional check has been added to verify that cores are online,

Hello,
Further looking at the code, when upcall_xlate is performed, we create a
hardcoded status block to represent the first packet:
stats.n_packets = 1;
stats.n_bytes = dp_packet_size(upcall->packet);
stats.used = time_msec();
stats.tcp_flags = ntohs(upcall->flow->tcp_flags);
Thanks Ben,

Thanks for your contribution.

There's no stats issue. Userspace just counts the number of packets it
sent and adds them in.
