Hi Dave,
This looks good to me. Just a minor nit for code cleanup. It could
be done in a separate patch or sometime later as well.

This umask() call could be moved little early right after bind() call and
that way we don't have to take care of calling umask(old_umask) in error
path if group name could not be found.
