I've just run into an issue with ipv6 (related to link local
addresses). I have a opensolaris server with an iscsi target (zfs
volume) and open-iscsi installed on my linux laptop. The reply from
the sendtarget request contains three IP addresses per target, like
this:

iscsiadm: finished reading text PDU, 48 hdr, 0 ah, 394 data, 2 pad
iscsiadm: >    TargetName=iqn.1986-03.com.sun:02:ed055ac1-c5f6-c691-

iscsiadm parses the first address of the first target, but fails on
the second target and aborts the whole operation. I have patched the
source to simply skip the line when it can't add the target record and
now it works fine.

Why is it that getaddrinfo() can't parse link local addresses?
iscsiadm: Cannot resolve host fe80::xxxx:xxxx:xxxx:xxxx. getaddrinfo
error: [Servname not supported for ai_socktype]
