I have a firewall forwarding rule with a logging option:
<rule family="ipv4"> <forward-port ... /> <log level="info"> <limit value="1/h"/> </log> </rule>
Checking my logs, they seem to have stopped after 2019-06-02.
Checking rpm logs, the last firewalld update was in May, so that can't be it. There have been fairly frequent kernel updates, not sure but maybe that's when the kernel 5.1 series came out?
I'm not very knowledgeable in iptables-verse, but I do see a reasonable iptable rule, "iptables -t mangle -n -L" shows:
Chain PRE_FedoraServer_log (1 references) target prot opt source destination LOG tcp – 0.0.0.0/0 0.0.0.0/0 tcp dpt:#### limit: avg 1/hour burst 5 LOG flags 0 level 6
But these log entries stopped dropping into /var/log/messages some time between 2019-06-02 and now. Anyone know if this is a known issue? Not sure who to file the bug against.
