I *think* that nvlist_add_string() and friends don't cope with a NULL value, which means that all of the places where optional strings turn up in an API need to cope with absence. I've commented on a few such places, but there's probably more...

lib/libcasper/services/cap_dns/cap_dns.c
198	Should this be prefixed with a if (nvlist_exists_string(nvl, "ai_canonname")), plus an initialization of canonname to NULL above?
228–229	Either one of hostname/servname can be NULL, which I don't think nvlist_add_string() copes with.
299	add && nvlist_exists_string(nvl, "host") ?
301	add && nvlist_exists_string(nvl, "serv") ?
517	Need to initialize both of these to NULL I think
577	check that host/serv are != NULL ?
597	Check for ai->ai_canonname == NULL?
616	Can hostname/servname be absent?
tools/regression/capsicum/libcasper/dns.c
49	Presumably these tests haven't been updated yet?

Update according to David suggestion.
I forgot to commit changes about test, thanks!
You make very good points.

lib/libcasper/services/cap_dns/cap_dns.c
198	dnvlist will be bather here but you are right we should check this value.
517	It's done. Just before memset.

551	This change should not be needed. The change in etc/mtree/BSD.root.dist will create the directory.

This revision now requires changes to proceed.Jan 8 2016, 6:55 PM

I updated Makefile.depnd which was pointed out byt @bdrewery.
I update also some dependencies in libnames and BSD.debug.dist.
