Function name_status_query() performs a node status query, so it really
should be called "node_status_query()" just to be consistent.
Yeah, minor... but it's looking as though an overhaul of namequery.c is in
order and I am trying to do the tiny changes that impact other stuff first.

This isn't the final version, of course, I still need to get WINS failover
working. This is just patched so it won't need lp_wins_server() (which I
renamed to lp_wins_server_list()).
I can't compile just now as something else is broken in HEAD. Let me know
if this version of namequery.c causes trouble down the line. Shouldn't,
as the changes are very small, but I've been known to rock the boat
before.

This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.
(This used to be commit debb471267960e56005a741817ebd227ecfc512a)
and the use of this function only increased timeouts when Samba queries
a broken DNS server.

We use the unexpected packed database.

with a PDC that has international netbios name and domain name. There's
still quite a bit of i18n stuff to fix though...
(This used to be commit 79045bd72ace9144e7dd73785b1d10a71b0d15aa)
list of structures rather than the dodgy parsing code we had before
this also gets smbw working correctly with no initial workgroup (using
name_status_find on __MSBROWSE__ returns)
(This used to be commit f2be88a8738a39ca5c98936edb7537cd701348a1)
to search for a DC to authenticate to using the "*" syntax than ensure
that for the first hour after the password change is searches for the
PDC using the 1B name not the 1C name as domain replication may not
have occured.

falling back to the UNIX calls on error. This should fix all problems with
smbd enumerating all users in all groups in all trusted domains via winbindd.
Also changed GETDC to query 1C name rather than 1b name as only the PDC
registers 1b.

If libsmb/namequery.c:name_query() times out while doing a non-broadcast
query, I mark that WINS server 'dead'. Note that I don't try the new
WINS server. I think I can get that working too.
This is only for queries, not registrations. The biggest problem is that
I may have to fiddle with the UNICAST SUBNET, but I need to check talk
that over with someone (Jeremy?) before I hack at it.
I can't actually test the above change, I'm 'fraid. I'm getting:
4 errors detected in the compilation of "rpc_server/srv_spoolss_nt.c".
in head branch.

(This used to be commit 40ae638866e3d826ccd5d827672634959c31b039)
string), the wins_srv module now hands back a struct in_addr when it's
called. It caches the IP address once it has been looked up. The IP
is cleared (and must be looked up again) if the 'wins server' parameter
is reread, or if the node is marked 'dead'. A dead node will not be
re-tried for 10 minutes (per a #define in wins_srv.c).
As it was, the code was reading the WINS server name or IP directly from
lp_wins_server. That's okay, except that if the value was expressed as
a name, then a DNS lookup would be done every time the client wanted to
talk to the server.
I still need to work out the implications of failover regarding the
'unicast subnet' list.
Chris -)-----
(This used to be commit 73aa188320fd3bf10b5dfc057323f40aff2c13bd)
*Note: failover doesn't actually work yet!* It's just that the code I'm
adding provides all of the pieces necessary.
I do have one big question. Something that I'll have to ask Jeremy, I'm
thinkin'. In nmbd/nmbd_subnetdb.c the IP of the WINS server is used to
set up the Unicast subnet.
...so what happens if the WINS server changes?
My guess is either:
a) nothing.
b) I'd have to change the unicast subnet entry whenever the WINS server
changes.
Urq.
BTW, the lp_wins_server() function no longer returns the WINS server name
or IP. It returns the list of WINS servers entered in smb.conf. To get
the currently 'live' WINS server, use the wins_srv() function.
Fun, eh?

only did a short-cut on an rcode of 3, which is 'name not found'. This
does a short-cut on any non-zero rcode. It also puts out a DEBUG message
(if DEBUGLEVEL is >= 3) detailing the error.

Negative Name Query Response. We should't wait through the timeouts and
retry twice if we've been told "No Such Entry".
(This used to be commit 2bbd16903db02aacb729d1ad140056b180e2a776)
semi-connection and a rpcclient prompt, but no functionality there yet.
Will be a few more days on that.
These files changed only with the addition of some support functions

the previous definition could result is us overflowing a buffer. The
null termination was always added yet the size returned did not
include the null termination.
the new function takes a BOOL null_terminate, and always returns the
total number of bytes consumed by the string.
(This used to be commit 426c90433396a95033eefcc4af97603abc934221)
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.
(This used to be commit b563be824b8c3141c49558eced7829b48d4ab26f)
I also fixed up the lookup_pdc_name() code so that it now works, even
with a NT server that insists on replying to udp/138.
The method I used to match packets was to use the mailslot string as a
datagram ID. The true dgm_id doesn't work as NT doesn't set it
correctly. uggh.
PS: Jeremy, I had to change your code quite a bit, are you sure this
worked with a Samba PDC?? The code looked broken, it got the offsets
wrong in the SMB portion of the packet and filled in the IP
incorrectly.
(This used to be commit 32f66f4ea63038cb4b3785bdf1762abdde076f5d)
this means "nmblookup -S" now always works, even with broken servers
the database stores all unexpected replies and these can be accessed
by any client.
while doing this I cleaned up a couple of functions, and put in place
a better trn_id generator. in most places the code got quite a bit
simpler due to the addition of simple helper functions.
I haven't yet put the code in to take advantage of this for pdc
replies - that will be next. Jeremys pdc finding code will then work :)
(This used to be commit 280e6359d36c9bc8dcded302f15c3a1db8e3feeb)
received properly when a UDP "retry" occurs. it's because reads and
writes must be interleaved / matched.
scenario:
nmblookup connects to agent, sends request.
agent receives request, broadcasts it on 137.
agent RECEIVES 137 broadcast, sends it to nmblookup
agent receives RESPONSE to 137 broadcast, sends it to nmblookup.
if reads are not equally interspersed with writes, then second send
will fail.
if you think this is odd behaviour and that the agent should be filtering
its own UDP traffic, think again.
agent will be, potentially, redirecting nmbd traffic (including WINS
server) not just client programs.
(This used to be commit 43e158c4261e51678d6e7f77ceb4a1c7281a2525)
created an "nmb-agent" utility that, yes: it connects to the 137 socket
and accepts unix socket connections which it redirects onto port 137.
it uses the name_trn_id field to filter requests to the correct
location.
name_query() and name_status() are the first victims to use this
feature (by specifying a file descriptor of -1).
(This used to be commit d923bc8da2cf996408194d98381409191dd81a16)
modified resolve_srv_name() to return dest host of *SMBSERVER if

still haven't decided what to do with the net* api yet...
(This used to be commit 29c480085e786905bfd92ea3cd93658f94e96e47)
Tidied up some of the mess (no other word for it). Still doesn't
compile cleanly. There are calls with incorrect parameters that
don't seem to be doing the right thing.
This code still needs surgery :-(.

(This used to be commit 18ff93a9abbf68ee8c59c0af3e57c63e4a015dac)
should allow us to call a function in swat rather than piping to
smbpasswd.
while doing this I also fixed quite a few "const char *" versus "char *" issues
that cropped up while using const to track down bugs in the code. This
led to changes in several generic functions.
The smbpasswd changes should be correct but they have not been
extensively tested. At least if I have introduced bugs then we should
be able to fix them more easily than before.

- support listing of foreign workgroups in /smb/
