podman: adding IPv6 section to 87-podman-bridge.conflist breaks host's ipv6 network access

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

Since I’ve gotten IPv6 connectivity recently set up to my CentOS 7 host, i wanted to start taking advantage and see how well Podman supports IPv6. This is as root (so not rootless).

After adding the relevant IPv6 section to /etc/cni/net.d/87-podman-bridge.conflist per the docs pages, then when starting a container, while a ping running on the host starts responding with ping: sendmsg: Network is unreachable

Steps to reproduce the issue:

add a 2nd array to original /etc/cni/net.d/87-podman-bridge.conflist as .plugins[0].ipam.ranges[1] (diff included below)
starting a ping on host: ping6 ipv6.google.com, responses start coming in as expected…
starting a (as root) container: sudo podman run -it --rm docker.io/library/alpine:3.11
see ping starts failing with errors: ping: sendmsg: Network is unreachable
additionally, container cannot reach the internet either and the only way to fix host ipv6 connectivity is to systemctl restart network

Describe the results you received:

a.) the host ipv6 networking is greatly affected (in effect being completely broken), this is really bad as it could cause an outage

b.) the container still has no ipv6 connectivity either

Describe the results you expected:

container should simply be able to reach the ipv6 network and the host ipv6 networking should not be affected at all!

Additional information you deem important (e.g. issue happens only occasionally):

issue always happens

+            }
           ]
         ]
       }

note: this happens even if i don’t update the routes section (though ultimately i’d like my container reachable on the internet).

per the above, the part that look of interest to me are when the actual pinging starts failing:

note: i am running podman 1.9 but patched with #6025 but it should not make any difference as this issue being discussed now is not using rootless mode.

Podman does not have IPv6 public support Therefore, switched to sync via emerge-webrsync. For some reason I cannot force emerge to use IPv4, might be an rsync (compile) issue More info: https://gith... — committed to kees-closed/compatibility-layer by kees-closed 4 years ago

There should be a dedicated flag for static IPv6 addresses (--ip6) but we haven’t wired it in yet. It’s actually a simple change - I’ll see about getting it landed in master tomorrow.

@mheon What is the scoop on this one?

rhatdan on Jul 6, 2020

I would love to take credit for that, but someone else did it, we just take advantage of it.
