From: Dumitru Ceara <[email protected]> Change the ovn-northd implementation to set the new 'controller_meter' field for flows that need to punt packets to ovn-controller.
Protocol packets for which CoPP is enforced when sending packets to ovn-controller (if configured): - ARP - ND_NS - ND_NA - ND_RA - DNS - IGMP - packets that require ARP resolution before forwarding - packets that require ND_NS before forwarding - packets that need to be replied to with ICMP Errors - packets that need to be replied to with TCP RST - packets that need to be replied to with DHCP_OPTS - BFD Co-authored-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Dumitru Ceara <[email protected]> --- lib/copp.c | 1 + lib/copp.h | 1 + northd/ovn-northd.c | 451 ++++++++++++++++++++++++-------------- ovn-nb.xml | 3 + tests/atlocal.in | 3 + tests/system-ovn.at | 119 ++++++++++ utilities/ovn-nbctl.8.xml | 1 + 7 files changed, 417 insertions(+), 162 deletions(-) diff --git a/lib/copp.c b/lib/copp.c index ac53a1094..7713046e5 100644 --- a/lib/copp.c +++ b/lib/copp.c @@ -37,6 +37,7 @@ static char *copp_proto_names[COPP_PROTO_MAX] = { [COPP_ND_NS_RESOLVE] = "nd-ns-resolve", [COPP_ND_RA_OPTS] = "nd-ra-opts", [COPP_TCP_RESET] = "tcp-reset", + [COPP_REJECT] = "reject", [COPP_BFD] = "bfd", };
