From f88b7a076be74a29a3bf876b4e2705f4a1ecf42b Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Wed, 24 Oct 2007 14:16:54 -0700 Subject: This is a large patch (sorry). Migrate from struct in_addr to struct sockaddr_storage in most places that matter (ie. not the nmbd and NetBIOS lookups). This passes make test on an IPv4 box, but I'll have to do more work/testing on IPv6 enabled boxes. This should now give us a framework for testing and finishing the IPv6 migration. It's at the state where someone with a working IPv6 setup should (theorecically) be able to type : smbclient //ipv6-address/share and have it work. Jeremy.
