@shuai.ma it might be end of day brain on my part, but I'm not seeing a Podman problem here.  The only call I see to Podman that I see in your notes is `podman version`. All of the other calls are to Docker, no?  Or have you aliased Podman to Docker?

hi Tom,
yes Podman aliased to Docker. 

BTW,
i tried to set following parameters during Podman run to workaround the issue, but had no effect. Does these settings not supported in container?
net.ipv6.conf.all.accept_ra=0
net.ipv6.conf.all.autoconf=0

BR, Shuai

Shuai, thanks for the update.  I think this is a Podman versus a podman-container issue, so I've changed the component.  @mheon could you take a look please?

Please provide the full output of `podman info` so we can determine network backend in use.

`   networkBackend: cni`

CNI plugins are in use. The Podman team recommends a migration to the Netavark network stack (as we are better able to support those when things go wrong); if that is impossible, we can reassign this issue to the CNI team for investigation.

hi Matthew,

is Netavark fully supported in RHEL 8.6 ?

BR, Shuai

update: change the network backend from cni to netavark, still the same problem.

Paul - mind taking a look? We're probably missing one of the v6 sysctls in macvlan.

hi Matthew, Paul, 
we see two issues in this mail. 

1. as titled, in a pure ipv4 macvlan network, creating a container got ipv6 global address. This is unexpected behaviour.

2. to workaround the #1 issue, i tried following parameters but all/any of them has no effect.
net.ipv6.conf.all.accept_ra=0
net.ipv6.conf.all.autoconf=0
net.ipv6.conf.default.autoconf=0

Are you planning to fix this or do you have any workaournd for any of the above 2 issues? our product is blocked by this issue.

BR, Shuai Ma

2) You cannot set sysctls because we setup the namespace before the oci runtime applies any sysctls. I think what you can try is running with a custom user namespace, e.g. --userns auto, in this case we have to setup the namespace after the oci runtime creates the namespace.

I think we have to fix it so netavark sets automatically the sysctls.

i tried like this, but no effect.
# docker run -itd --name c1 --ip=10.85.41.247 --network nic0 --sysctl net.ipv6.conf.all.autoconf=0 flex.io/uss-engine:17.0

tried set net.ipv6.conf.all.forwarding=1, it has effect. Does net.ipv6.conf.all.forwarding and net.ipv6.conf.all.autoconf applied at differnet phase?

BTW, when would we expect a fix for this?

Thanks a lot!

please be noticed that any 'docker' command here is actually 'podman' as we aliased Podman to Docker.

I'm hoping to clear up some of the confusion between teams.

The sysctl must be set before you run Podman or it will not effect things.  Can you confirm whether you have set the sysctl before running Podman with netavark?  If not, please try and report back.

The good news is one of our engineers has been able to reproduce the bug you observe.  One of us will update this bugzilla with results.

Update: disregard the suggestion for a work-around.  We have verified it does not work.

As mentioned before you have to create a custom userns, only then the sysctl will be applied before netavark is called.

This works for me `podman run --uidmap=0:0:4294967295 --sysctl net.ipv6.conf.default.autoconf=0 ...`, the important bit is --uidmap=0:0:4294967295 but any other userns (e.g. --userns auto) should also work.

upstream fix -> https://github.com/containers/netavark/pull/434

i see the fix is in netavark, do you plan to add that fix in cni as well? 

repeat my question - does netavak fully support RHEL8.6?

BR, Shuai

@mrussell can you answer https://bugzilla.redhat.com/show_bug.cgi?id=2126243#c24 please?

@shuai.ma Netavark was Tech Preview in 8.6 but we are changing that to fully supported in the documentation soon. You can consider it supported in 8.6 now.

hi, 
our product is now using CNI backend instead of Netavark, can you provide fix to Cni as well? 

BR, Shuai

@shuai.ma That should be raised in a new bug, however, we are not planning to make this fix in CNI. We understand that workaround is being tested with a plan to converge on Netavark in the future. Thank you and regards.

Test with netavark-1.5.0-4.module+el8.8.0+18060+3f21f2cc.x86_64. The auto_conf_ipv6 already disabled inside container. And checked inside container only a linked-local ipv6 addr set. So move it to verified. More details:
