Merge branch 'master' of ssh://git.samba.org/data/git/samba
commit fe36fe8c3e76e3dd7c66ecdf7254dc01c5d065c0
Author: Jelmer Vernooij <jelmer at samba.org>
Date: Thu Oct 23 20:41:15 2008 +0200
Use common net utility code (address and sockaddr manipulation).
commit d1bc7e56d0584ef4f1051e39cd1a81182d63f096
Author: Jelmer Vernooij <jelmer at samba.org>
Date: Thu Oct 23 19:56:09 2008 +0200
Rename same_net to same_net_v4 for consistency with Samba 3.
commit d6a5476ee7af464a381bbeeec576ee58f3650a43
Author: Jelmer Vernooij <jelmer at samba.org>
Date: Thu Oct 23 19:53:15 2008 +0200
Use sockaddr_storage only where we rely on the size, use sockaddr
otherwise (to clarify we can also pass in structs smaller than
sockaddr_storage, such as sockaddr_in).
commit 55fd6b125c3e5ac135d124c291f5ae6102fcbb2f
Author: Jelmer Vernooij <jelmer at samba.org>
Date: Thu Oct 23 18:56:37 2008 +0200
Remove support for obsolete data type "ipv4address"
