Add start of IPv6 implementation. Currently most of this is avoiding IPv6 in winbindd, but moves most of the socket functions that were wrongly in lib/util.c into lib/util_sock.c and provides generic IPv4/6 independent versions of most things. Still lots of work to do, but now I can see how I'll fix the access check code. Nasty part that remains is the name resolution code which is used to returning arrays of in_addr structs. Jeremy.

Modified fix for bugid #784. Based on a patch from moriyama@miraclelinux.com (MORIYAMA Masayuki). Don't use nstrings to hold workgroup and netbios names. The problem with them is that MB netbios and workgroup names in unix charset (particularly utf8) may be up to 3x bigger than the name when represented in dos charset (ie. cp932). So go back to using fstrings for these but translate into nstrings (ie. 16 byte length values) for transport on the wire. Jeremy. (This used to be commit b4ea493599ab414f7828b83f40a5a8b43479ff64)

Modified fix for bugid #784. Based on a patch from moriyama@miraclelinux.com (MORIYAMA Masayuki). Don't use nstrings to hold workgroup and netbios names. The problem with them is that MB netbios and workgroup names in unix charset (particularly utf8) may be up to 3x bigger than the name when represented in dos charset (ie. cp932). So go back to using fstrings for these but translate into nstrings (ie. 16 byte length values) for transport on the wire. Jeremy. (This used to be commit b4ea493599ab414f7828b83f40a5a8b43479ff64)

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.

Add start of IPv6 implementation. Currently most of this is avoiding IPv6 in winbindd, but moves most of the socket functions that were wrongly in lib/util.c into lib/util_sock.c and provides generic IPv4/6 independent versions of most things. Still lots of work to do, but now I can see how I'll fix the access check code. Nasty part that remains is the name resolution code which is used to returning arrays of in_addr structs. Jeremy.

Add start of IPv6 implementation. Currently most of this is avoiding IPv6 in winbindd, but moves most of the socket functions that were wrongly in lib/util.c into lib/util_sock.c and provides generic IPv4/6 independent versions of most things. Still lots of work to do, but now I can see how I'll fix the access check code. Nasty part that remains is the name resolution code which is used to returning arrays of in_addr structs. Jeremy.

this looks like a big commit, but it isn't really :) This fixes our netbios scope handling. We now have a 'netbios scope' option in smb.conf and the scope option is removed from make_nmb_name() this was prompted by a bug in our PDC finding code where it didn't append the scope to the query of the '*' name.

Modified fix for bugid #784. Based on a patch from moriyama@miraclelinux.com (MORIYAMA Masayuki). Don't use nstrings to hold workgroup and netbios names. The problem with them is that MB netbios and workgroup names in unix charset (particularly utf8) may be up to 3x bigger than the name when represented in dos charset (ie. cp932). So go back to using fstrings for these but translate into nstrings (ie. 16 byte length values) for transport on the wire. Jeremy. (This used to be commit b4ea493599ab414f7828b83f40a5a8b43479ff64)
