All rules are now created in the libvirt private firewall chains. The
code for deleting rules will try to delete from both the original
builtin chains and the new private chains in order to cleanup properly
during upgrades.
This finally fixes a very old bug (from 2008!) related to traffic
between guests on distinct virtual networks. The intention is that
networks never allow incoming connections, but the old ordering of rules
meant that we would mistakenly allow accept traffic from whichever
network was most recently created.
With everything going into the FORWARD chain there was interleaving of
rules for outbound traffic and inbound traffic for each network:
ACCEPT all -- * virbr2 0.0.0.0/0 192.168.123.0/24 ctstate RELATED,ESTABLISHED
ACCEPT all -- virbr2 * 192.168.123.0/24 0.0.0.0/0
ACCEPT all -- virbr2 virbr2 0.0.0.0/0 0.0.0.0/0
REJECT all -- * virbr2 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable
REJECT all -- virbr2 * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable
ACCEPT all -- * virbr0 0.0.0.0/0 192.168.122.0/24 ctstate RELATED,ESTABLISHED
ACCEPT all -- virbr0 * 192.168.122.0/24 0.0.0.0/0
ACCEPT all -- virbr0 virbr0 0.0.0.0/0 0.0.0.0/0
REJECT all -- * virbr0 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable
REJECT all -- virbr0 * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable
So the rule allowing outbound traffic from virbr2 would mistakenly
allow packets from virbr2 to virbr0, before the rule denying input
to virbr0 gets a chance to run
With the split up forwarding chains, all incoming deny rules are checked
before any of the outgoing allow rules, as rules are grouped into three
distinct sets
Cross rules
ACCEPT all -- virbr2 virbr2 0.0.0.0/0 0.0.0.0/0
ACCEPT all -- virbr0 virbr0 0.0.0.0/0 0.0.0.0/0
Incoming rules
ACCEPT all -- * virbr2 0.0.0.0/0 192.168.123.0/24 ctstate RELATED,ESTABLISHED
ACCEPT all -- * virbr0 0.0.0.0/0 192.168.122.0/24 ctstate RELATED,ESTABLISHED
REJECT all -- * virbr2 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable
REJECT all -- * virbr0 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable
Outgoing rules
ACCEPT all -- virbr2 * 192.168.123.0/24 0.0.0.0/0
REJECT all -- virbr2 * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable
ACCEPT all -- virbr0 * 192.168.122.0/24 0.0.0.0/0
REJECT all -- virbr0 * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable
