First it would be best if you comment on the patch code where it is relevant.
Second why did you drop email addresses from CC that's not polite.

But to your point. The two places I added return checks is because they
only fail in BSD, in Linux they succeed regardless. So it's related.

The difference between Linux and BSD is that in BSD struct sockaddr
has an sa_len field that gets set by getsockname() but in Linux the
slen is hard-coded and there is no such field in struct sockaddr.

Other then that I added some prints in the error paths, again, because they
might fail only on BSD. I don't see the point of adding the prints in a separate
patch.
