Description

Changed the scope of this BZ from first 3 patches to all the I-P patches. OSP13 will be moving to OVN 2.11 and since OSP13 is long time release, it makes sense to backport all the I-P patches. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2019:2943 Hi Numan, Can you help tell how to reproduce and verify this bug? We don't know how to create the ofctrl/pinctrl events in OVN.Thanks! Hi Haidong Li, One thing to verify is that this should not result in any regressions. This is more of a functional change. Regarding the pinctrl evebts, rrom any VM you can actually flood GARPs, dhcp requests and this should not result in flow recomputation. To verify this you can probably check the CPU usage. Thanks Numan verified on the latest version:ovn2.11-2.11.1-3.el7fdp
steps:
1.run test case "regression_bz1695722" manually to send lots of dhcp packets
2.send GARP packets with scapy:
from scapy.all import *
ip='172.16.{y}.{x}'
mac='00:de:ad:01:00:{z}'
for i in range(10,99):
for j in range(10,99):
sendp(Ether(src=mac.format(z=j),dst="ff:ff:ff:ff:ff:ff")/ARP(op=1,hwsrc=mac.
format(z=j),hwdst="00:00:00:00:00:00",psrc=ip.format(x=i,y=j),pdst=ip.format(x=i
,y=j)),iface="eth1")
cpu usage is not high:
