Public bug reported:
iptables was working fine until I did an upgrade to a new kernel
version. Now it is impossible to load my firewall rules using iptables-
restore. The iptables-restore program croaks when trying to load the
rules.
While the error is reported on the line associated with the "COMMIT"
statement, it appears that it is really failing when the "-j LOG" option
is used. If I eliminate the "-j LOG" option on statements, it seems to
work normally (like it did before).
When I run lsmod, there is no "xt_LOG" or "ipt_LOG" module present. I
cannot find the "xt_LOG.ko" or "ipt_LOG.ko" file anyplace, so I cannot
load them manually.
Not sure if this is a kernel bug or an iptables bug, but since it makes
it impossible to load my firewall rules and leaves my system wide open,
it's definitely a security issue.
