[Bug 782] New: -j LOG --log-prefix handling broken
http://bugzilla.netfilter.org/show_bug.cgi?id=782
Summary: -j LOG --log-prefix handling broken
Product: iptables
Version: CVS (please indicate timestamp)
Platform: x86_64
OS/Version: All
Status: NEW
Severity: normal
Priority: P5
Component: iptables-restore
AssignedTo: netfilter-buglog at lists.netfilter.org
ReportedBy: hvtaifwkbgefbaei at gmail.com
Estimated Hours: 0.0
instead of the parameter I give to the LOG module, "NETFILTER drop ",
it ends
up getting mangled to "--log-prefix".
excerpt from a file I feed to iptables-restore:
-A LDROP -d 255.255.255.255/32 -p udp -j DROP
-A LDROP -d 77.223.39.255/32 -p udp -j DROP
-A LDROP -m hashlimit --hashlimit-above 1/min --hashlimit-mode srcip,dstip
--hashlimit-burst 1 --hashlimit-name logldrop --hashlimit-htable-expire 60000
-j DROP
-A LDROP -m limit --limit 5/s -j LOG --log-prefix "NETFILTER drop "
--log-tcp-options --log-ip-options --log-uid --log-macdecode
-A LDROP -j DROP
iptables-restore succeeds. then:
# iptables -nvx --list LDROP
Chain LDROP (4 references)
pkts bytes target prot opt in out source
destination
0 0 DROP udp -- * * 0.0.0.0/0
255.255.255.255
0 0 DROP udp -- * * 0.0.0.0/0

"--log-prefix"
1 44 DROP all -- * * 0.0.0.0/0
0.0.0.0/0
now I have kernel messages like this:
<4>[440059.429055] --log-prefixIN=eth0 OUT= ...
If I now do "iptables -I LDROP -j LOG --log-prefix ...", --log-prefix
option
parsing works OK. Also, iptables-save works.
I use iptables git 8db1044ba608a.
previous version of iptables I had, from 20111119, worked ok. now I only
upgraded iptables and glibc (to fedora 2.15-32.fc17; I made a testcase for
xtables_save_string , so I guess strspn+strpbrk were not broken by glibc
upgrade).

With Debian's iptables 1.4.14-2:
1. iptables --line-numbers -L chain
shows the wrong prefix, which is --log-prefix.
2. I was getting the wrong prefix only after booting into self compiled kernel
from Debian's 3.2.20-1 linux source package. On the short time when I was
using
self compiled kernel from Debian's 3.2.19-1 linux source package and
Debian's
iptables 1.4.14-2, I didn't see it.
3. There is another user reporting at http://bugs.debian.org/678499.

I can confirm this bug ever since upgrading to iptables 1.4.14-2 on Arch Linux,
x86-64. Prior to this iptables version "-j LOG --log-prefix" worked
fine.
Here is a fragment my rules:
iptables -A INPUT -i eth1 -m limit --limit 100/hour -j LOG --log-prefix
"Filter
BLKD INPUT GTW:"
iptables -A INPUT -j DROP
Output:
