Subject: Possible iptables 4.4.11 issues

One of the Shorewall Beta testers just installed iptables 1.4.11 and is
seeing a couple of anomalies. Before I run off and change Shorewall, I
would like to confirm that these are intentional changes in iptables
behavior and not bugs:

Using kernel 2.6.39, iptables 1.4.10 and xtables-addons 1.35

The following rules file entry:

ACCEPT  $FW  lan  tcp  22  -  -  -  !root:root

produces the following iptables rule:

-A fw2lan -p 6 --dport 22 -m owner ! --uid-owner root ! --gid-owner root -j
ACCEPT

Which works.

After upgrading iptables to 1.4.11 the following iptables-restore error
is produced:

iptables-restore v1.4.11: owner: option "--uid-owner" cannot be inverted.


The following tcrules file entry:

IPMARK(dst,-1,-64)  $FW  eth1  tcp  888

produces the following iptables rule:

-A OUTPUT -p 6 --dport 888 -o eth1 -j IPMARK --addr
dst --and-mask -1 --or-mask -64 --shift 0

Which works.
After upgrading to iptables 1.4.11 the following iptables-restore error is
produced:

iptables-restore v1.4.11: IPMARK: Bad value for "and-mask" option: "-1"

Thanks,
