stuff and also fix a pile of nmbd bugs. Unfortunately I found it very
hard to disentangle the new features from the bug fixes so I am
putting in the new code. I hope this is the last big pile of changes
to the 1.9.16 series!

can't test the multi group changes.
I also found that some of lukes changes wiped out some recent bug
fixes. Is your CVS tree ok luke?

- added multiple workgroup code - samba can register under different
(unique) NetBIOS aliases, one per workgroup it joins.

DFLT_SERVER_TYPE in nameserv.h
- got rid of a lot of spurious domain controller stuff. Samba is not a
domain controller yet, but it can be a domain master. We were claiming
to be a domain controller in some packets which may have caused
problems
- don't do preferred master startups on the WINS pseudo-net
- don't do election requests on the WINS pseudo-net
- fix a nasty bug in become_non_master() which wiped out the bits in
remove_type before using them. The result was that samba didn't like
losing its master status.
- changed the logic in the election packet handling to enable us to
become a non-master whenever we receive a winning election frame, even
if we aren't expecting it
- get another packet from the socket in nmbd when we reject one of our
own packets, this stops us from going into the packet reading code too
often and makes nmbd much snappier
- always remove a name immediately when we try to release it, don't
wait for the lack of response from the network, otherwise we will end
up replying to name that we don't really own. We still send the dereg
packets, we just don't wait for them to time out.

that samba uses possible
- added "socket address" option to allow virtual SMB servers (on
systems with IP aliasing line Linux)
- disabled FAST_SHARE_MODES by default in Linux as older Linux boxes
can't do shared writeable mappings. We really need autoconf ...
- added new option types in loadparm so a string type can be specified
ot be uppercase only, this is used for the workgroup and netbios name
options
- auto-create the lock directory if it doesn't exist in shared mem
startup
- get rid of announce_backup()
- change a few comments in nmbd code
- rewrote the chaining code completely. Hopefully it will handle any
depth chains now.
- added LPRng support

- made the lp_string() code able to handle any length string
- got rid of the obsolete lmhosts code, instead users should use
"interfaces" and "remote announce". lmhosts now is just used as a IP
to netbios name map
- cleanup the inet_address() code

of samba's NetBIOS name.

bug spotted in nameservresp.c - arguments to test subnet the response
is received on (same_net()) were the wrong way round (ccm@shentel.net)
samba was adding WORKGROUP(1e) as a unique not a group name: fixed this
bug in reply_name_status() and reply_name_query(): WINS entries weren't
being looked up.
name status reply adds local SELF entries to WINS SELF entries: some
SELF entries are only added locally, while others are only added via
WINS. name status needs to have both, combined.
a sync will only occur when an ANN_LocalMasterAnnouncement is received, NOT
an ANN_HostAnnouncement or an ANN_DomainAnnouncement.
when samba is a member of a workgroup, it looks for (using a wins server)
and announces to its domain master. NAME_QUERY_ANNOUNCE_HOST - yet another
'state' - has been created to do this: do the name query on the wins server
and send the announce host to the answer to this query.
jeremy @ vantive wrote the original code to do this, which used the
name_query() function. i'm trying to avoid name_query: it times out and
generally messes things up, but using queue_netbios_packet() and
queue_netbios_pkt_wins() is... not intuitive?

namedbname.c:search_for_name() wasn't looking for 0x1b as well as
0x0 and 0x20 name types.
reduced number of retransmissions of packets from 4 to 3 times.
added code that ensures remote lmhosts entries don't get deleted when
a master browser cannot be found on a remote subnet. stopped forcing
an election on remote subnets if a master browser cannot be found.
stopped browse list and wins list from being written out too frequently.
only add samba's names to local interfaces.
add 0x1c name if we are a domain logon machine (needs more exploration).
why bother reloading services when receiving a SIGTERM?
sort out add_my_name_entry() and remove_name_entry() to deal with
broadcast, samba as a WINS and samba using a WINS. properly.
added extra debug information to help with expected response queue code.
updated debug comments in become_master().
altered dump_names() DEBUG format. it looks prettier.
altered wins.dat format to match DEBUG format.

created namedb*.c nameservresp.c nameservreply.c and namepacket.c
added modules to Makefile, downloading dan's current version first :-)
shuffled docs to match source
created more docs
fixed bug in announce_backup() discovered when going nameannounce.doc:
backup list requests to the master browser should be used when samba is
not a master browser; backup list requests to the primary domain
controller should be used when samba is not a primary domain controller.
fixed bug in sync_server: it would never send MasterAnnounce packets.
removed the code that ignored special browser names: these should only
be ignored (except 0x1b names) when broadcasted name queries are sent,
not when directed registration or directed queries are sent samba as a
WINS server. (note: exactly what's going on is still uncertain).
renamed NAME_QUERY_MST_SRV_CHK to NAME_QUERY_PDC_SRV_CHK (more accurate).
renamed NAME_STATUS_MST_SRV_CHK to NAME_STATUS_PDC_SRV_CHK (more accurate).
added secured WINS name registration: a new 'state' NAME_REGISTER_CHALLENGE;
functions send_name_response(), response_name_query_register(); added
sending of WAIT ACKNOWLEDGEMENT packet; added a reply_to_ip field to
the response record structure so that after the name query challenge,
you know who to inform of the outcome of that challenge.
note: these are all currently untested modifications (yikes!)

some bugs fixed / documented and some discrepancies noted down (in
namework.c as well as namework.doc)
namebrowse.c and namelogon.c contain functions that were inappropriately
placed in namework.c. namebrowse.c contains browse sync queue management
functions that were inappropriately placed in namedb.c
the 'cmd_type' member of response_record has been renamed to 'state'
because that more accurately reflects it purpose (not entirely. sigh).
fixed a bug in nameserv.c that meant the previous version wouldn't
compile.
there's probably a bit more...

accidentally updated the Makefile
updated the name database structure (again!). this time, there is one
name database per local interface. there is also a pseudo-interface on
ip 255.255.255.255. its purpose is to store WINS name entries. all the
local interface name databases store SELF names only. the WINS name
database stores non-special browser names.
added wins.dat file: records WINS entries in ascii format. this is reloaded
when nmbd restarts.
added repeating code for response packets. timer is in seconds only at the
moment.
updated the response queue code to deal with samba registering with a
WINS server a bit better (added more cases when a response isn't received).
tidied up the response packet processing code and expire_response_queue()
code. added cross references between response received and await-response
expired code.
added over-zealous code that checks all machines that register with samba
as a WINS server (every 10 minutes i think): to see whether they are still
alive or not (see rfc1001.txt)
bug reported by terry@ren.pc.athabascau.ca: DNSFAILed names _stay_ as
DNSFAIL, even though the machine may come back up and REGISTER.
removed update_from_reg() function. it's not necessary, and it does too much.
added code that announces on each local interface samba's ttl as zero and
servertype as zero when nmbd is kill -TERMed
first attempt at putting the first functionality of samba browsing back in
(remote subnets should have samba appear in a workgroup specified through
the lmhosts file)
lots of other miscellaneous tidying up / chopping about.

and Netmask, instead replacing them with calls to routines in
interface.c
- got rid of old MAXINT define
- added code to ensure we only return one entry for each name in the ipc
enum routines
- added new_only option to add_netbios_entry() to prevent overwriting
of important names
- minor time handling fixup

- added dir_check_ftype() to clean up the file type checking a bit
- added check for libc version >= 5 for setfsuid() for Linux
- moved the AM_MASTER() and related macros to nameserv.h
- added proper defines for the various netbios announce types
- don't call the announce_backup() code, as I'm pretty sure its wrong
it sent ANN_GetBackupListReq packets as broadcasts, they are supposed
to be used only by clients to the master browser to find a list of
available backup servers to remote a netserverenum to, I don't think
nmbd should ever send one.
- fixed a bug in the browse list writing
- minor debug cleanups
- put in the code to discard our own broadcasts (it won't work for
multi-homed hosts though)
- changed ELECTION_VERSION to 1 so we can be beaten by a NT 3.51 server by
lowering the os level.
- only do sync_browse_lists() if we are the master browser, otherwise
we'll cause network overload
- don't call tell_become_backup() as it appears to be badly broken, it
should only be used when the machine being told has its MAINTAIN_LIST
to to auto. Not calling it does no great harm anyway
- fix a nasty bug where becomebackup was confused with reset browser!
- make setbuffer() not get caught by the auto protototypes

I've now got WINS registration working, and refresh working. Its
looking pretty good so far, but needs lots of testing.

The biggest thing is the integration of Lukes new nmbd. Its still
largely untested, so we will really need some feedback
I've also added auto prototype generation and cleaned up a lot of
minor things as a result
