Fix IPv6 support on OpenBSD

[danieljakots]

Hi,

Before

$ scapy
INFO: Can't import PyX. Won't be able to use psdump() or pdfdump().
usage: ifconfig [-AaC] [interface] [address_family] [address [dest_address]]
[parameters]
INFO: No IPv6 support in kernel
WARNING: No route found for IPv6 destination :: (no default route?)
Welcome to Scapy (2.3.2)

$ python2.7 scapy/tools/UTscapy.py -t test/regression.uts -f html -l -o /tmp/scapy_regression_test.html
[...]
PASSED=739 FAILED=28

After

$ scapy
INFO: Can't import PyX. Won't be able to use psdump() or pdfdump().
Welcome to Scapy (2.3.2)

$ python2.7 scapy/tools/UTscapy.py -t test/regression.uts -f html -l -o /tmp/scapy_regression_test.html
[...]
PASSED=750 FAILED=17

It seems to start normally on FreeBSD.

Thanks for reporting & fixing this issue!

If you run the tests as root, do all tests pass? I'm a bit afraid by the FAILED=17!

Will this code work with previous versions of OpenBSD also?

[danieljakots]

Thanks for the quick answer :)
Yeah with root: PASSED=759 FAILED=8
The failing tests are the ones which need to be killed:
^Cfailed 11411EF4 Automaton state overloading
^Cfailed A23A30FE Automaton condition overloading
^Cfailed B819945C Automaton action overloading
^Cfailed F047D75C Automaton priorities
^Cfailed A662DF42 Automaton test same action for many conditions
^Cfailed 8E2F0534 Automaton test io event
^Cfailed 0816811E Automaton test io event from external fd
^Cfailed C06AB0CF Automaton test interception_points, and restart

I have the same result (PASSED=748 FAILED=8) with scapy 2.1.0 which we currently have in our ports tree.

For the previous version of OpenBSD, there's no reason that it wouldn't work as the ifconfig format didn't change at lease for the last few releases.

Thanks!

That automaton tests is something I want to investigate anyway.
