Description

Found as a consequence of the discussion here: https://github.com/firewalld/firewalld.github.io/pull/14 Eric has sent patches for new zone/policy files to be shipped with libvirt to fix this issue, and it's being discussed on the upstream mailing list: https://listman.redhat.com/archives/libvir-list/2022-May/231200.html I can reproduce this bug with firewalld-1.0.0-4.el9.noarch
1. Start the firewalld on 2 hosts;
2. On host 1, start a route network:
<network connections='2'>
<name>br1</name>
<uuid>8a2e947d-c1d5-4695-2881-5f877ced63e0</uuid>
<forward mode='route'/>
<bridge name='br1' stp='on' delay='0'/>
<mac address='52:54:00:07:f7:41'/>
<ip address='10.0.0.1' netmask='255.255.255.0'>
<dhcp>
<range start='10.0.0.2' end='10.0.0.254'/>
</dhcp>
</ip>
</network>
3. On host 1, start 2 VMs connected to this network;
4. Test the 2 VMs can ping each other, and the guest can ping host;
5. The VM can not ping host 2;
6. On host 2, which are in the same subnet of the host 1, add a static route:
# ip route add 10.0.0.0/24 via 10.73.xx.xx dev eno1
(10.73.xx.xx is the ip of host 1)
7. VM ping host2, succeed
8. Host2 ping vm, failed:
# ping 10.0.0.115
PING 10.0.0.115 (10.0.0.115) 56(84) bytes of data.
From 10.73.xx.xx icmp_seq=1 Packet filtered
From 10.73.xx.xx icmp_seq=2 Packet filtered
……
With old firewalld firewalld-0.9.3-2.el9.noarch:
Step 8 will succeed
# ping 10.0.0.145
PING 10.0.0.145 (10.0.0.145) 56(84) bytes of data.
64 bytes from 10.0.0.145: icmp_seq=1 ttl=63 time=0.569 ms
64 bytes from 10.0.0.145: icmp_seq=2 ttl=63 time=0.484 ms

This message is a reminder that Fedora Linux 35 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 35 on 2022-12-13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '35'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 35 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed. This was resolved upstream with Commit 7f7a09a2d2, which is in libvirt-8.10.0. |
