This rule

$IPTABLES -A RULE_0_in  -j LOG  --log-level notice --log-prefix "DENY  in: "


result with linux 3.6-rc5

Sep 12 06:37:29 xxxxx kernel: <5>DENY  in: IN=eth0 OUT= MAC=.......


result with linux 3.5.3 and older:

Sep  9 10:43:01 xxxxx kernel: DENY  in: IN=eth0 OUT= MAC......


Thanks

auto75914331@hushmail.com reports that iptables does not correctly
output the KERN_<level>.

$IPTABLES -A RULE_0_in  -j LOG  --log-level notice --log-prefix "DENY  in: "

result with linux 3.6-rc5
Sep 12 06:37:29 xxxxx kernel: <5>DENY  in: IN=eth0 OUT= MAC=.......

result with linux 3.5.3 and older:
Sep  9 10:43:01 xxxxx kernel: DENY  in: IN=eth0 OUT= MAC......

commit 04d2c8c83d0
("printk: convert the format for KERN_<LEVEL> to a 2 byte pattern")
updated the syslog header style but did not update netfilter uses.

Do so.

would be better to avoid the %c

->

 sb_add(m, KERN_SOH "%c%sIN=%s OUT=%s ",
	'0' + loginfo->u.log.level, prefix,

v2: Use KERN_SOH and string concatenation instead of "%c" KERN_SOH_ASCII
as suggested by Eric Dumazet.
