[ovs-dev] Failed to execute unit test: system-traffic.at: conntrack - floating IP

[Vasu Dasari]

Hi,

I am running into an error when I try to run the system-traffic test case -
"conntrack - floating IP". Actually, any test case which is using this in
the testsuite is failing:
ADD_VETH(p0, at_ns0, br0, "10.1.1.1/24", "f0:00:00:01:01:01")

Command used to run the test:
sudo make -C _build-gcc/ check-system-userspace TESTSUITEFLAGS='-k
"conntrack - floating IP"'
Ububtu Kernel: 5.3.0-46-generic
OVS Version: Latest master

Relevant supporting log from system-userspace-testsuite.log

=====
../../tests/system-traffic.at:5757: ip netns exec at_ns0 sh <<

Found a reference to this kind of error at
https://bugzilla.redhat.com/show_bug.cgi?id=1550097
This was from last April.

If I execute the command from bash, the same is successful:
====
$ sudo ip netns exec at_ns0 bash
$ ip link set dev p0 address "f0:00:00:01:01:01"
$ ip link show p0
11: p0 at if10: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP mode DEFAULT group default qlen 1000
    link/ether f0:00:00:01:01:01 brd ff:ff:ff:ff:ff:ff link-netnsid 0

Any idea why this command is failing only in OVS environment?

Thanks
