Hi,

In article <[🔎] E12fIHE-0006lG-00@fountain.labs.futuretv.com> (at Wed, 12 Apr 2000 09:13:31 +0100), Philip Blundell <pb@labs.futuretv.com> says:

I've already submitted some patches for glibc to support sin6_scope_id
including some getaddrinfo() / getnameinfo() extension (*); and, in fact,
sin6_scope_id is already included in the cvs version.

(*) draft-ietf-ipngwg-scopedaddr-format-01.txt

Unfortunately, linux-2.4 kernel may break userlands if we don't compile 
them with sin6_scope_id; and binary which were not compiled with 
sin6_scope_id won't work on linux-2.4 systems.  
On the other hand, binary with sin6_scope_id will run on old kernels 
(but of course, it cannot handle scope correctly). 

So, linux-2.4.0 being released, we should update glibc and rebuild
some packages as soon as possible...


Note: The getipnodeby{name,addr}() functions are (or will be) deprecated; 
      we should use getaddrinfo() and getnameinfo().
