TPROXY sockets already contain the original information of the socket on getsockname and getsockopt SOL_IP, 0x50 is known to cause problems in some situations when using TPROXY.

I have tested these patches against both REDIRECT based forwards and TPROXY based forwards on the GHS router with both ipv6 and ipv4 with this patch on top of tor- (Gentoo ebuild) and they both worked like a charm :)

I reviewed the code and I couldn't find anything strange either. So for me you have a go ahead :) Thanks a lot for the patch!
