Firewalld issue #5568

JuSt19 · 2020-03-20T11:29:22Z

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

/kind bug

Description

Once we deploy the microservices within podman with selinux and firewalld (both activated)...services start not responding requests properly. If you connect to the container and try to ping, dig any internal or external domain, any action to verify the connection, the pod is not able no do nothing, if we restart the pod but first with firewalld and selinux disabled...everything is ok and all back to normality.

Steps to reproduce the issue:

Activate Firewalld
Deploy two containers:
podman run --name nginx01 -d -p 8080:80 nginx
podman run --name nginx02 -d -p 8081:80 nginx
Stop firewalld
Try to make internal DNS query or external such as google or something...

Describe the results you received:

root@4d01a46cd8c7:/# ping 10.88.0.3
PING 10.88.0.3 (10.88.0.3) 56(84) bytes of data.
From 10.88.0.2 icmp_seq=10 Destination Host Unreachable
From 10.88.0.2 icmp_seq=11 Destination Host Unreachable
From 10.88.0.2 icmp_seq=12 Destination Host Unreachable
From 10.88.0.2 icmp_seq=13 Destination Host Unreachable

root@8d9d9097cc6e:/app# ping subdomain.domain.com
ping: subdomain.domain.com: Temporary failure in name resolution

When the microservice try to connec to SQL Server:
SqlExceptionHelper","message":"The connection attempt failed."

Describe the results you expected:

The possibility to make dns querys and connect to other services such as sql

@mheon PTAL

I don't think this is an SELinux issue, but I am willing to be proven wrong? If you put the machine in permissive mode, does it still fail with the file wall rules up?

Are there any AVC messages in the audit.log.

This issue looks a lot like a firewall rules.

From the podman info this looks like it is happening with root.

BTW There should be a newer version of podman available for centos.

check out it's not the same I had a while back, confusion between iptables and firewalld: #5335

I have updated the main issue with more information and also the title, this issues is focused in firewalld.

I've talked yesterday with @mheon and he asked me to do some tests and here's the output:

[root@test-podman-01 ~]# podman exec -it nginx02 bash

When i try to restart the pod and get back to live again, i receive the following error:

I have found this links about the same issue in the same env:

I feel like we may have fixed this on master, but I'm not precisely sure as to when...

@JuSt19 There's a Centos virt-sig repo that distributes more up-to-date Podman packages; would you be willing to give those a shot and see if a more recent version is fixed? @lsm5 where did that repo live, again?

JuSt19 · 2020-03-23T13:27:28Z

@mheon that's perfect for me, could you please share to me this repo and then i'll test if it's already fixed.

Awaiting!

I don't maintain the virt-sig repo anymore. All non-fedora and non-rhel is on OBS now. 1.8.2 should be available for centos 7 via the OBS stable repo. See the Kubic project section under CentOS at https://podman.io/getting-started/installation for installation instructions

Still failing after update to 1.8.2 and doing the same thing to reproduce the same with the old version.

Hello, is there any progress on this? I am experiencing the same issue on CentOS 8. When firewalld is enabled. Basically name resolution does not work whereas routing works fine when using ips directly.

mheon · 2020-04-09T13:29:09Z

@mccv1r0 Any thoughts on this one?

cfelder · 2020-04-09T13:29:40Z

This may be related to #5335. I am currently not using the kubic repos but with the version provided in AppStream repos for CentOS 8

podman-1.6.4-2.module_el8.1.0+272+3e64ee36.src.rpm

a wrong CNI configuration is created containing iptables as backend for the firewall plugin.

This is easy to reproduce using:

$ podman network create newnetwork
$ podman network inspect newnetwork | grep backend
				"backend": "iptables",

when removing the backend line name resolution works fine.

baude · 2020-04-09T13:57:00Z

this is a known issue and is fixed upstream ... both the network create code and default cni config

cfelder · 2020-04-09T13:58:39Z

any chance getting this into the releases shipped with the base/appstream repos on rhel?

rhatdan · 2020-04-09T14:02:23Z

Is it fixed in podman-1.16.4? Which should be released in rhel8.2 release.

rhatdan · 2020-04-09T14:02:47Z

We will release podman-1.9.* in RHEL8.2.1 in the summer time.

cfelder · 2020-04-09T14:05:43Z

Looking forward to see this and hopefully dnsmasq plugin in the next release. Meanwhile I can workaround this by myself.

Thanks a lot.

mheon · 2020-04-09T14:15:02Z

Can you confirm whether there is a firewall block in the base network we ship (87-podman-bridge.conflist)?

cfelder · 2020-04-09T14:19:43Z

For podman-1.6.4-2.module_el8.1.0+272+3e64ee36.src.rpm there is the following block:

        {
            "type": "firewall",
            "backend": "iptables"
        }

mheon · 2020-04-09T14:25:10Z

Alright. So we are at least shipping a vaguely working config, here.

A friendly reminder that this issue had no activity for 30 days.

rhatdan · 2020-06-09T19:03:32Z

@mheon Is this still an issue with the upstream?

mheon · 2020-06-09T19:04:50Z

This should be fixed on upstream CNI configs.
