Hi Andrew & Alan,

I noticed that in 2.4.2ac20, all netfilter logs come
to
the console, whatever the log levels, and the
beginning
of the line is always prepended with '<4>'.

I found in printk.c that a test is done for the length
of the message to be strictly larger than 3 chars. But
ipt_LOG uses 2 consecutive printk, one with only '<4>'
and one with the message. It may be possible that
other
drivers to the same. Looking back in patches show this
is present since 2.4.2ac13.

This trivial patch allows a 3-char message to set the
message level.

Cheers,
Willy
