Description of problem:
Just did an 'up2date' for my Linux Redhat 7.3 machine which installed,
amoung other things, kernel v2.4.20-13.7. Previously I was working
with v2.4.18-27.7.x where the command:

'iptables -t mangle -A OUTPUT -j MARK --set-mark 1 -m owner --uid 501'

used to work without issue.

Now, when giving the same command under the new kernel (with a verbose
option this time) gives:

'iptables -v -t mangle -A OUTPUT -j MARK --set-mark 1 -m owner --uid
501

MARK  all opt -- in * out *  0.0.0.0/0  -> 0.0.0.0/0  OWNER UID match
501 MARK set 0x1
iptables: Invalid argument
'

lsmod shows the ipt_owner module loaded, amoung others, so I know the
module is working. I checked the source for the module but could not
for the life of me determine what the problem is here.

Rebooting to the old kernel seems to allow this command to work again.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Boot into newest kernel for RH 7.3 Athlon
2. type iptables -t mangle -A OUTPUT -j MARK --set-mark 1 -m owner --uid
501
3. Should return "iptables: Invalid argument"
