Subject: Pass protosw instead of domain structure to soalloc() to get real
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=94b0822958d17d21744eef4d9f216afecd44427e;p=openbsd

Pass protosw instead of domain structure to soalloc() to get real
`pr_type'. The corresponding domain is referenced as `pr_domain'.
Otherwise dp->dom_protosw->pr_type of inet sockets always points
to inetsw[0].
