returned as an index plus offset into the valudated_users table.
The offset (100) is added so that an smb_uid of zero becomes
an invalid value. All access into the validated_users table are
done by removing the offset and indexing into the table. Out of
ranges return NULL. Causes accesses into the validated_users table
to be more consistant and controlled.
This change made due to the fact that the uid field is only 16
bits in the smb header and we need for this not to be a unix
user id (which can ge 32 bits).

int uid's. Part of the change for Samba to return an index+offset
into the registered users table rather than a raw unix uid.
Added casts to required prototypes for function pointers in
tables.

(This used to be commit ec2a3a1cf2)
Removed AS_USER requirement for SMBulogoff. A valid TID (cnum) is not
given for this call, which become_user needs if it is not to return
an error. This fixes a specific case with NT4.0 which stops users
attaching to a Samba server using a different account to the one they
are logged in under.
(This used to be commit c65a2cdd83)
however dead_netbios_entry() is still thinking that no response has
been received when the response_record times out for the registration
with the WINS server. only print a debug message when no registration
response is _really_ received from the WINS server.

too short)
- got rid of many unnecessary calls to time(NULL) in nmbd. They were
causing it to chew too much CPU time when idle. Now we pass a time
value in from the top level.
(This used to be commit 3cd7303dbc)
(compiler bugs were the problem)
- minor password cleanups (catch WfWG bug where it sets the password
to a space instead of a NULL)
- fix printing problem for kanji users
- minor cleanups
(This used to be commit 92566ecc31)
Luke, can you take special note of the bug fixes to nmbd so you can
propogate them to your new code.
- rewrote the code that used to use fromhost(). We now call
gethostbyaddr() only if necessary and a maximum of once per
connection. Calling gethostbyaddr() causes problems on some systems so
avoiding it if possible is a good thing :-)
- added the "fake oplocks" option. See the docs in smb.conf(5) and
Speed.txt
- fixed a serious bug in nmbd where it would try a DNS lookup on
FIND_SELF queries. This caused a lot of unnecessary (and incorrect)
DNS lookups to happen. FIND_SELF queries should only go to the
internal name tables.
- don't set FIND_SELF for name queries if we are a wins proxy, as we
are supposed to be answering queries for other hosts.
- fixed a bug in nmbd which had "if (search | FIND_LOCAL)" instead of
"if (search & FIND_LOCAL)". Luke, this was in nameservreply.c
- the above 3 bugs together meant that DNS queries were being cached,
but the cache wasn't being used, so every query was going to DNS, no
wonder nmbd has been chewing so much CPU time! Another side effect was
that queries on names in lmhosts weren't being answered for bcast
queries with "wins proxy" set.
- ignore the maxxmit for seconday session setups (see CIFS spec)
- close user opened files in a uLogoffX for user level security (see
CIFS spec)
- added uid into the files struct to support the above change
(This used to be commit ea472b7217)
- change debug level on clitar stuff
- define MAP_FILE if not defined
- ensure we never set authoritative on queries in nmbd
- fake a positive response to SMBioctl, apparently this is needed for
some WfWg printer drivers
- deny file access for non-fcbopen queries when (access_allowed == AREAD && flags == O_RDWR)
- add sys_waitpid()
(This used to be commit 61e3116e57)
set the mode on all created files. I think this is a better policy.
- change the debug levels on some items
- fix a charset handling bug which affected foreign and extended
charset users
- no longer switch back to the original directory when idle, instead
switch to / as the original directory may not be readable by ordinary
users.
- fix some bugs where the create mode of files was not being
explicitly set (it was relying on the umask and using fopen). Not a
big bug as it only affected obscure commands like the messaging ops.
- got rid of the lock code in the lpq cache as its no longer needed
- rewrote smbrun to be faster and to remove the security hole. We now
don't actually need a external smbrun binary, its all done by smbd.
- add a more explicit warning about uids and gids of -1 or 65535
(This used to be commit 5aa735c940)
The 1.9.16 tree is now back to 1.9.16p2 as far as nmbd is concerned
apart from a small change that fixes the announce type in two places.
(This used to be commit 45e66a69d3)
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!
(This used to be commit 20b6203dac)
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?
(This used to be commit 8b7fe224bc)
- added multiple workgroup code - samba can register under different
(unique) NetBIOS aliases, one per workgroup it joins.
lkcl
(This used to be commit f24e341e7e)
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.
(This used to be commit eb84f2f342)
correctly if there were multiple instances of a name. This led to the
infamous "not enough memory" error when browsing (but this isn't the
only cause of that message)
- fix a triple-chaining bug which affected OpenX following a TconX
- fix a serious nmbd bug that meant nmdb would answer packets that it
wasn't supposed to, causing havoc with browse lists.
- never time out SELF packets. This is an interim fix until I find out
why nmbd thought they should be timed out.
(This used to be commit 2960c3908c)
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
(This used to be commit e9eac6cd49)
- redid tridge's fprintf for storing wins.dat, and yet again removed the
unsigned long changing it to a unint32.
lkcl
(This used to be commit bb57170695)
- made nb_flags an unsigned 16 bit int in nameserv.h
- nmbd was calling add_my_subnets() with an uninitialised parameter group.
removed it.
lkcl
(This used to be commit 3d55e54156)
- you can now press enter after a password prompt with "smbclient -L
hostname" and it will use a blank username and password, the same as
if you used -U%
- changed the wins.dat store code to not go via a string variable
(just use fprintf instead)
- removed a "unsigned long" that luke put back in, changing it to
uint32 to keep 64 bit machines happy. Naughtly luke!
- allow guest non-connnected print queue listings so ms client 3 can
work
(This used to be commit 917160dee6)
it doesn't support loading of Internet Group names yet, but then again,
you can't create Internet Group names yet, so it's not a problem!
(This used to be commit 960aad39ac)
- changed the order of PROGS and SPROGS in Makefile (SPROGS first)
- another 64 bit cleanup (for INADDR_NONE)
- added paranoia code in DirCacheAdd() to detect looping
- fixed important DirCache flush bug
- rewrote the NetServerEnum code after I found it could return servers
from multiple workgroups at once, and this could cause browsing
havoc. Now a null workgroup query is equivalent to a query for the
servers primary workgroup
- got rid of my_workgroup()
- got rid of "workgroup = *" comment in Makefile. We no longer support
a workgroup of *, users must set the workgroup explicitly
- the wins.dat file was being stored in a different format to what it
was being loaded in - this could cause havoc. fixed.
- uppercase our netbios name and the workgroup name at startup
- if accept fails in main loop when running as a daemon then continue,
don't just exit!
- don't use ./ on smbclient in smbtar
- better code to detect if a process exists
(This used to be commit ec3d539630)
- 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
(This used to be commit be2b679403)
Bressler)
- machten support from Trevor Strohman (trev@figment.tenon.com)
- added qinfo command to client as part of drag-and-drop printer
support for win95 from David Chappell <chappell@mouse.cc.trincoll.edu>
He also added the "printer driver" option
- use sigblock() on more systems and use sigsetmask(0) instead of
sigunblock() as its more portable. This beats a problem with zombies
on heavilily loaded systems.
- added internals.doc written by David Chappell into the source tree
- get rid of PRINT_COMMAND options from local.h as they are no longer
relevent
- new kanji code from Fujita
- don't set the recursion_available flag on queries in nmbd
- fix a potential bug with pointer subtraction in printing.c
- got rid of error_count code as the real fix (the EOF problem) is now
in
(This used to be commit aa6f8b04d1)
lewis2@server.uwindsor.ca. rest of this patch to follow.
bug in interface.c - uninitialised pointer.
nmbd has 0x20 as well as 0x0 NetBIOS name when lmhosts entry is added.

(This used to be commit 2b9475cc5f)
to be done on this function when doing an announce host to a remote
domain master browser when samba is a WINS server.
lkcl
(This used to be commit 12c50bac4e)
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?
lkcl with help from jra
(This used to be commit 6e932e4bae)
NetServerEnum with no workgroup attached if the workgroup is
"WORKGROUP" (the default in the Makefile) and uses the specific
NetServerEnum (with workgroup attached) otherwise.
(This used to be commit 6fa3468c9b)
namedbname.c:find_name_search() needed search capability on both local
subnet records and WINS records. it used to return NULL if the name
was not found in the local subnet records even if you asked it to search
the WINS name records as well.
(This used to be commit 96c2efded8)
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.
lkcl

previous commit (see previous log message for details)
fixed bug in nameservreply.c: wrong macro in use (RSSVAL not IVAL!).
did another make proto
lkcl
(This used to be commit d78b319062)
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!)

is now performed in stages: wait for each NetBIOS name to be
successfully registered before proceeding to the next stage.
tied implicit name registration and release (broadcast method) to the
same piece of code as explicit method (via WINS server).
created special_browser_name() function that checks __MSBROWSE__
name: this name is ignored by WINS servers apparently.
fixed likely incompatibility between refresh_my_names() and add_my_names().
(netbios entries were unlikely to be refreshed).
NOTE: none of these changes have been tested. at all.
lkcl
(This used to be commit 7719fb0652)
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...
lkcl
(This used to be commit a66417ebe8)
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.
(This used to be commit 7e8c60cfe5)
also added paranoid code in the main process() loop of smbd to detect
when smbd is looping uselessly. This should stop the "smbd is chewing
lots of cpu" reports
(This used to be commit 8e9dce34d5)
prototypes automatically using "make proto". This is much less prone
to error than the old method of manually adding prototypes
(This used to be commit b551dc98f7)
- fixed problem with installscripts if srcdir is not set
- fixed ptr init bug in interface.c
- changed default lookup type in nmblookup to match nbtstat under NT
- new quotas fixes for sunos and solaris
(This used to be commit e775576f02)
- added iface_count() and iface_n_ip() routines so its easy to loop
over the local interface list
- made readsize a normal loadparm global
- check for null w in add_domain_entry()
- set the deathtime to time()-1 for doamin entries with servertype==0
This allows servers that are shutting down to be removed
- add the 0x1c name at startup if we are a WINS server. Previously we
added it only if we were a master
- loop over interfaces in add_my_domains(), so people don't have to
have a lmhosts file to get lp_workgroup() on all interfaces
- set add to True for find_workgroupstruct() in nmbsync, and check for
null return
- remove some ugly "errno = EBADF" bits. they just confused things.
(This used to be commit 88b191b488)
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
(This used to be commit 7ed71b73ae)
- 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
(This used to be commit cfbad9b082)
I've now got WINS registration working, and refresh working. Its
looking pretty good so far, but needs lots of testing.
(This used to be commit 045014aa57)
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
(This used to be commit 0d8dcfa13c)
- added setfsuid() support (for Linux)
- started adding some of Lukes changes, just the loadparm and ipc ones
so far
