No more PHYSIN in iptables INPUT rules in kernel 3.11.3

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



FYI: I created the following redhat bugzilla bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1019743Since upgrading to
Fedora 19 kernel iptables processing apparently no longer has the notion
of a PHYSIN device (in case of a bridge interface) for INPUT rules. PHYSIN
is no longer available in iptables logging, nor is it matched by any
rules.Version-Release number of selected component (if applicable):
kernel-3.11.3-201.fc19.x86_64

Steps to Reproduce:
1. Add iptables rules like this:
   iptables -I INPUT -i br1 -m conntrack --ctstate NEW  -j LOG
--log-prefix NOPHYSIN
   iptables -I INPUT -i br1 -m conntrack --ctstate NEW  -m physdev
--physdev-in vnet+ -j LOG --log-prefix PHYSIN
2. Note that the logging shows only NOPHYSIN messages and no PHYSIN
messages
3. Note that the counters for the first rule are updated while the
counters for the second remain 0

Additional info:
Previous (working kernel): kernel-3.9.4-200.fc18.x86_64

A selection from our syslog demonstrates the issue. At about 10:10:00 the
system was rebooted, after that PHSYIN is lost for INPUT rules:
