Adds support for xtables v11 support + fix for segfault. This supercedes and thus closes #173.

Hi @seglberg

the issue is the same. Your commit was already in PR #173, and I also tried it.

The code that raises an error is:

import iptc

table = iptc.Table(iptc.Table.NAT)
chain = iptc.Chain(table, "PREROUTING")
print "name: ", chain.name
print "rules: ", chain.rules

As you can see, it is very simple code, and it fails in two different ubuntu 16.04: server and desktop

Thanks @dealfonso, I was able to reproduce the issue.
I have some spare time later this afternoon, I will take a look then.

Okay give it a try now. I missed a change to the xtables_globals struct.

I think that this structure is not needed anymore

[mmellison]

👍 Cleaned up by removing the unused class.

Hi, I have been checking this commit in a complex app (https://github.com/dealfonso/ipfloater) and it is working properly.

Okay great to hear.

@ldx any chance of getting this merged in and getting a new version published to pypi?

[ldx]

Sure, let me also test this first though.
