ERROR: Log level INFO requires LOG Target in your kernel and iptables

Hi,

I have 2 Debian testing boxes running a very similar setup (both running
the latest aptosid kernel); on one of them, since the
iptables/libxtables10 packages have been upgraded from 1.4.19.1-1 to
1.4.20-2, shorewall-init can''t start shorewall anymore and for this
reason ifupdown also fails triggering firewall up.

Shorewall can be successfully started later on, and ifupdown starts
working too; in /var/log/shorewall-init.log I found a possible reason:

[...]
Aug 30 14:07:32 Shorewall up triggered by lo
Aug 30 14:07:32 Shorewall up triggered by lo
Aug 30 14:07:32 Shorewall up triggered by --all
Aug 30 14:07:36 Processing /etc/shorewall/params ...
Aug 30 14:07:36 Processing /etc/shorewall/shorewall.conf...
Aug 30 14:07:36 Loading Modules...
---> Aug 30 14:07:37    ERROR: Log level INFO requires LOG Target in
your kernel and iptables
Aug 30 14:09:28 Shorewall up triggered by wlan0
Aug 30 14:09:28 up on interface wlan0 ignored
[...]

Trying to downgrade iptables to the previous version seems to fix the issue.

Oddly enough, the other box works perfectly even with the new version of
iptables, and shorewall6 doesn''t seem affected on both boxes.

Do you have any hint?

Thanks


Maurizio

Re: ERROR: Log level INFO requires LOG Target in your kernel and iptables

I made some interesting finds I''d like to share.

iptables 1.4.20 introduced a new locking mechanism to avoid failures
during concurrent invocations [1]; a -w option has been introduced in
order to have iptables wait until lock is released, and it seems that
the issue can be solved by enabling that feature.

I''d like to file a bug report, but I''m wondering whether to
file it
against shorewall or against iptables, since its locking/wait mechanism
should probably be enabled by default in order to ensure the iptables
command will really do what is expected to. Any opinions?

Thanks,


Maurizio

Re: ERROR: Log level INFO requires LOG Target in your kernel and iptables

Hi,

good question.

First, I am not sure if I experience the same problem:

On my Gentoo test systems with shorewall-4.5.19 and shorewall-4.5.20
(not yet in tree), both require iptables-1.4.20, I don''t see a problem
on boot with shorewall-init (not yet in tree, too) nor shorewall itself
(the test systems have both, IPv4 and IPv6 connection, so I am using
shorewall and shorewall6).

But: If I restart an interface (/etc/init.d/net.eth0 restart), Gentoo
will first stop all depending services, which include shorewall and
shorewall6, bring down the interface, bring up the interface again and
will finally start the previous stopped depending services (=shorewall
and shorewall6) again.

That''s the point where I see a failure like yours, sometimes:

shorewall is unable to start because some iptables modules aren''t yet
ready. Keep in mind: shorewall was up an running before... without any
problems:

I can immediately start shorewall manually (/etc/init.d/shorewall start)
and it will start without any problems. So this looks like a timing
issue, right.

Is this the same you are talking about?

The failing modules are exactly the same as here, ipt_LOG (xt_LOG) and
iptable_raw; in my case the firewall fails at boot, while later it
behaves normally; pre-loading those modules at boot doesn''t help, and
since I have both shorewall and shorewall6, sometimes fails the first,
sometimes the second. It took me some time to figure out what was
happening the first time I booted and the network didn''t work.

I''m testing 3.11 kernel now: all the same. Weird.

It looks the very same problem to me.

The new locking code in ip[6]tables 1.4.20 prevents iptables and
ip6tables from running simultaneously unless the -w option is specified
on both. You can work around this problem temporarily by using a
capabilties file:

	shorewall show -f capabilities > /etc/shorewall/capabilities
	shorewall6 show -f capabilities > /etc/shorewall6/capabilities

I''ll have a patch to the compiler available in a day or so.

Re: ERROR: Log level INFO requires LOG Target in your kernel and iptables

I''m getting this in a case where there is no ip6tables in use. Is there
a
workaround for this? Its using the Shorewall from Debian stable.

# shorewall version
4.5.5.3

# shorewall try /etc/shorewall

Re: ERROR: Log level INFO requires LOG Target in your kernel and iptables

# iptables --version
iptables v1.4.8

the machine is running Debian 6 with some Debian 7 packages including
shorewall, but I can''t upgrade iptables to the Debian 6 version without
also upgrading a bunch of system libraries. As its a Xen VPS at a hosting
company I''m reluctant to do that. Wheezy has iptables 1.4.14 available.

Hi,

Seems like you are running a custom kernel.

Have you verified that you kernel has support for LOG target at all?

Check for CONFIG_NETFILTER_XT_TARGET_LOG.

Re: ERROR: Log level INFO requires LOG Target in your kernel and iptables

I don''t have access to the config file the kernel was built with. How
would
I otherwise find out?

I find these kernel modules with ''log'' in their names and
there doesn''t
seem to be a match. If the kernel doesn''t have this compiled in does
that
mean that shorewall cannot operate and theres no workaround? Because,
honestly, I can live without firewall logging of any kind on this server.

root@hk2server:/lib/modules# find 3.4.0-cloud/ -iname \*log\*

Well, modprobe/modinfo xt_LOG should also give you a hint.

I agree,

# modinfo xt_LOG
filename:       /lib/modules/3.4.60/kernel/net/netfilter/xt_LOG.ko
alias:          ip6t_LOG
alias:          ipt_LOG
description:    Xtables: IPv4/IPv6 packet logging

This is missing on you system.

Not sure if it is possible to replace the usage of xt_LOG in shorewall
with ULOG or NFLOG. I guess Tom is able to answer that.

Yup... and it''s good that you cannot live without logging.

Can''t you contact support or the person/company who/which created the
system/kernel image you are using?

Replacing LOG with ULOG is described at

You can replicate the test for the LOG target that the rules compiler
performs as follows:

	iptables -N foo
	iptables -A foo -j LOG
	iptables -F foo
	iptables -X foo

If the second command fails, then you have no LOG target support.

Re: ERROR: Log level INFO requires LOG Target in your kernel and iptables

I tested with iptables -N foo ; iptables -A foo -j ULOG and that was fine,
so it looks like the kernel does have ULOG support. So I followed the
recipe in the doc to convert to ULOG;

root@hk2server:/etc/shorewall# grep -v ^\# * | egrep
''\$LOG|ULOG|LOGFILE''
params:LOG=ULOG
shorewall.conf:LOGFILE=/var/log/messages
shorewall.conf:MACLIST_LOG_LEVEL=$LOG
shorewall.conf:TCP_FLAGS_LOG_LEVEL=$LOG
shorewall.conf:RFC1918_LOG_LEVEL=$LOG
shorewall.conf:LOGUNCLEAN=$LOG

No rules or policies are configured to log. Its running ulogd

Still getting the same error

With those policies, why have a firewall?

At any rate, please ''shorewall check -T'' and forward the

Re: ERROR: Log level INFO requires LOG Target in your kernel and iptables

Believe it or not, the firewall is doing something. Mostly its rate
limiting and sanity checking.  We are working toward a more robust firewall
but our application is pretty sensitive to closed ports and doesn''t
have a
connection tracking module. Shorewall is definitely helping, even at this
stage though, on our other servers. This is the only one with any shorewall
problem.

Here is the output as requested;

S_FILTER_LOG_LEVEL defaults to ''info'', so you need to change
iot.

The attached simple patch will catch cases like this.

  patch /usr/share/shorewall/Shorewall/Config.pm < DEFAULT_LOG.patch

It applies with an offset on 4.5.5.3.

I also suspect that the concurrency bug addressed in iptables 1.4.20
caused some problem in the past: with shorewall apparently working,
sometimes psad complained there was no LOG target in the firewall.

The latest 4.5.21-Beta1 version seems to perfectly fix all the iptables
related issues in my case; I''d only like to suggest some cosmetic
improvement on the shorewall-init boot messages on Debian:

Initializing "Shorewall-based firewalls": Compiling...
/var/lib/shorewall/firewall is up to date -- no compilation required
echo_notdone
Compiling...
/var/lib/shorewall6/firewall is up to date -- no compilation required
echo_notdone
done.

Thanks a lot,


Maurizio

Steve,

The compiler supports that option and is defaulting its value to
''info''.
What I suggest you do is:

	shorewall update

		That will create a new shorewall.conf file that 	
		contains all of the options supported by your version.
		Your old file will be renamed shorewall.conf.bak.

	Modify the new shorewall.conf file as needed.

Same here for Gentoo: 4.5.21-Beta1 fixes the restart problem.
