[fixed] Re: linuxulator problems in linux_socket.c (and friends)

[Andrew Atrens <atrens@xxxxxxxxxxxxxxxxxx>]

The following patch works around the problem, but is probably not as correct
as it could be -

looks like the probable root cause is that IP_HDRINCL sockopt is only
handled for IPRAW sockets but the linux_sendto() code doesn't test for this
before calling kern_getsockopt() ...

there might be some subtlety that I'm missing here but on the surface that
seems to be it ... :)

Cheers,

Andrew.
