Please provide all the detail of your environment, what distro? Which version of bats, firewalld, ncat, iptables, etc...

sit0@NONE: mtu 1480 qdisc noop state DOWN mode DEFAULT group default qlen 1000\ link/sit 0.0.0.0 brd 0.0.0.0

Looks like you are using the sit kernel module? If this device is automatically added to all network namespaces then this will break many test assumptions. I recommend to disable that if you want to run the tests.

Thanks very much for your respond!

BTW, do you mean netavark only works without CONFIG_IPV6_SIT or only the netavark tests works without CONFIG_IPV6_SIT?

We use an embedded Linux based on https://www.yoctoproject.org. And the related packages version as below:

 # rpm -qa | grep bats
bats-1.11.0-r0.core2_64
# rpm -qa | grep firewalld
firewalld-1.3.2-r0.core2_64
# which ncat
/usr/bin/ncat
# rpm -qf /usr/bin/ncat
nmap-7.80-r0.core2_64
# rpm -qa | grep iptables | grep -v iptables-module
iptables-1.8.10-r0.core2_64

[Luap99]

I am talking about the tests only, but I am not familiar with CONFIG_IPV6_SIT so I wouldn't know for sure.
The main issue here is that having a second interface besides lo will break the test assumptions as we make sure that netavark deleted the interfaces by simply counting all interfaces and we only expect lo to be there (at least for one of the linked failures above). I suggest you try to run them without the kernel module loaded.

I have no idea about the firewall-cmd ones, timeout seems odd. If you do not use firewalld then I would suggest you just ignore/disable them.

For the ncat maybe the 5 seconds is not enough in your env so maybe try giving it more here

netavark/test/helpers.bash

For some reason, we can't disable CONFIG_IPV6_SIT as it built-in kernel, not via module. Could you help to provide the cases which are maybe affected by sit module?

Yes, we did not use firewalld, is there only options provided to skip the cases as I notice not any 200-bridge-firewalld.bats includes the test related to firewalld, but also 250-bridge-nftables.bats includes firewalld cases?

nsenter -n -t "${CONTAINER_NS_PIDS[$container_ns]}" timeout --foreground -v --kill=10 5 \

After a simple search, it seems the timeout is hardcoded, is it possible to provide a option to configure timeout?

Thanks you very much!

Sorry I don't have time to look into that, my only suggestion is to build the kernel without it to run the tests and see how the results differ.

There are some special cases that need to check that the iptables and nftables integration works with the firewalld reload service. I think it is possible to move them into the firewalld file as well but not a priority.

I would suggest to bump the timeout in our tests, none should have a need to configure this. If 5s is not enough everywhere we can increase it by default.

After disable CONFIG_IPV6_SIT, some of the above failed cases did pass, but only two of them as below.
iptables - bridge teardown
iptables - port range forwarding dual - udp

And could you help to confirm again, if the netavark only works with CONFIG_IPV6_SIT disabled. Or just the netavark tests need to disable CONFIG_IPV6_SIT. If just the tests need, maybe improving the tests to make the tests work with CONFIG_IPV6_SIT is helpful.

But there still some cases failed such as:

I have no idea about the firewall-cmd ones, timeout seems odd. If you do not use firewalld then I would suggest you just ignore/disable them.

Yes, we did not use firewalld, is there only options provided to skip the cases as I notice not any 200-bridge-firewalld.bats includes the test related to firewalld, but also 250-bridge-nftables.bats includes firewalld cases?

There are some special cases that need to check that the iptables and nftables integration works with the firewalld reload service. I think it is possible to move them into the firewalld file as well but not a priority.

Thanks your feedback! It's more helpful if move the firewalld related tests in one file and I sent a PR as #994.

For the ncat maybe the 5 seconds is not enough in your env so maybe try giving it more here

netavark/test/helpers.bash

Line 647 in 395ace5

nsenter -n -t "${CONTAINER_NS_PIDS[$container_ns]}" timeout --foreground -v --kill=10 5 \

After a simple search, it seems the timeout is hardcoded, is it possible to provide a option to configure timeout?

I would suggest to bump the timeout in our tests, none should have a need to configure this. If 5s is not enough everywhere we can increase it by default.

After a quick search for

netavark/test/helpers.bash

Line 647 in 395ace5

nsenter -n -t "${CONTAINER_NS_PIDS[$container_ns]}" timeout --foreground -v --kill=10 5 \

, do you mean change the hardcoded timeout value?

BTW, is it possible to print the test result into a file? That is to say, gather the output as below into a file.

Which version of ncat are you using? ncat 7.95 works for me on SUSE/openSUSE but 7.97 fails. Fedora ships an older 7.92 version because of license issues.
