fixed typo in SPOOLSS_SYNT
some cleanup of unused functions
wrote make_spoolss_enumprinter and make_spoolss_openprinterex for
rpcclient as I'm trying to keep in sync the parsing code between HEAD and
TNG.
Will commit changes to TNG after lunch.
J.F.
rewrote the printer notify code, so now it's compatible with SP5 and fully
dynamic. No more limits on printers and job lists.
removed the make_xxx() functions as they are not used and broken
fixed a bug in the open handle function.
J.F.
OpenPrinterEx is now decoding correctly the query
most of the EnumXXX use the new_buffer struct.
check the (un)marshalling return code.
conclusion: still a long way to go. all the client code has to be
rewritten, and I still wonder how to implement correctly the notify stuff.
is *missing* from samba cvs main, therefore it is set to all zeros.
this will cause, amongst other things, administrator-changing-user-passwords,
and setting up new accounts, to fail, as the user's password can only be
decoded with the session key (in this case, the administrator's usr sess key).
it's never a perfect world, is it?
done a minimal amout of clean-up in the Makefile, removing unnecessary
modules from the link stage. this is not complete, yet, and will
involve some changes, for example to smbd, to remove dependencies on
the password database API that shouldn't be there. for example,
smbd should not ever call getsmbpwXXX() it should call the Samr or Lsa
API.
this first implementation has minor problems with not reinstantiating
the same services as the caller. the "homes" service is a good example.
pdus, and then feeds them over either a "local" function call or a "remote"
function call to an msrpc service. the "remote" msrpc daemon, on the
other side of a unix socket, then calls the same "local" function that
smbd would, if the msrpc service were being run from inside smbd.
this allows a transition from local msrpc services (inside the same smbd
process) to remote (over a unix socket).
removed reference to pipes_struct in msrpc services. all msrpc processing
functions take rpcsrv_struct which is a structure containing state info
for the msrpc functions to decode and create pdus.
created become_vuser() which does everything not related to connection_struct
that become_user() does.
removed, as best i could, connection_struct dependencies from the nt spoolss
printing code.
todo: remove dcinfo from rpcsrv_struct because this stores NETLOGON-specific
info on a per-connection basis, and if the connection dies then so does
the info, and that's a fairly serious problem.
had to put pretty much everything that is in user_struct into parse_creds.c
to feed unix user info over to the msrpc daemons. why? because it's
expensive to do unix password/group database lookups, and it's definitely
expensive to do nt user profile lookups, not to mention pretty difficult
and if you did either of these it would introduce a complication /
unnecessary interdependency. so, send uid/gid/num_groups/gid_t* +
SID+num_rids+domain_group_rids* + unix username + nt username + nt domain
+ user session key etc. this is the MINIMUM info identified so far that's
actually implemented. missing bits include the called and calling
netbios names etc. (basically, anything that can be loaded into
standard_sub() and standard_sub_basic()...)
at present, a unix password is missing from the unix credentials, but is
not _actually_ expected to be needed. weeelll... maybe :-)
this is used to transfer credentials between smbd and msrpc daemons, down
a unix socket, so that the unix and nt credentials can be inherited by
an msrpc daemon called up from smbd.
damn, this one is bad.
started, at least two days ago, to add an authentication mechanism to
the smbd<->msrpc redirector/relay, such that sufficient unix / nt
information could be transferred across the unix socket to do a
become_user() on the other side of the socket.
it is necessary that the msrpc daemon inherit the same unix and nt
credentials as the smbd process from which it was spawned, until
such time as the msrpc daemon receives an authentication request
of its own, whereupon the msrpc daemon is responsible for authenticating
the new credentials and doing yet another become_user() etc sequence.
one horrible cut / paste job from smbd, plus a code split of shared
components between the two.
the job is not _yet_ complete, as i need to be able to do a become_user()
call for security reasons. i picked lsarpcd first because you don't
_need_ security on it (microsoft botched so badly on this one, it's not
real. at least they fixed this in nt5 with restrictanonymous=0x2).
fixing this involves sending the current smb and unix credentials down
the unix pipe so that the daemon it eventually goes to can pick them
up at the other end.
i can't believe this all worked!!!
if microsoft bothered to publish it. actually, there are good reasons
for not publishing it: people might write programs for it, and then
those programs wouldn't work on nt5, for example...
some of the server-side stuff. Realloc() was being used, so it

have the string max length = string length + 1.
if not, then it gets its knickers in a twist over whether the string
is NULL-terminated or not.
four days.
four days i spent on this one.
reg_io_r_info() working properly. previously they weren't well
understood (well, they were the first of the registry functions i did,
back in december 97, ok??? :-)
set ntversion to 0x1 in SAMQUERY, so that we reply same as NT4 srv.
these _may_ not actually ever get used, as trust relationships
really need to be established with shared secrets, and you need
to get the SID of the trusted and trusting domains, so this
may have to go in a private/xxx.mac file.
for which a PDC is responsible. typical answers are:
<Name of Domain> plus <Builtin>.
against a hierarchical, down-level-compatible NT5 PDC, there's likely to
be more than these two entries!!!!!
- disabled (AGAIN) the GETDC "if (MAILSLOT\NTLOGON)" code that will get
NT5rc2 to work but WILL break win95 (AGAIN). this needs _not_ to be
re-enabled but to be replaced with a better mechanism.
- added SMBwrite support (note: SMBwriteX already existed) as NT5rc2 is
sending DCE/RPC over SMBwrite not SMBwriteX.
char*
UNISTR2*
SID*
decided to create a higher-order function set, add_item_to_array()
free_item_array().
higher-order support routines needed to add a new type:
type* item_dup(const type*)
void item_free(type*)
of course, strdup() and free() are perfect, pre-existing examples
of such functions, used in the implementation of add_chars_to_array()
and free_char_array().
sid_dup() and free() work for the add_sids_to_array() and free_sid_array()
implementations.
use unistr2_dup() and created unistr2_free() because the functionality
behind these may change into something horrible, like [horror] dynamic
memory allocation of the UNISTR2 character array. argh!!!!
jean-francois, this function set implements what we talked about over...
a year ago, now :-)
works with command-line completion on the service name (ohh yesss, this
is becoming my favourite bit of functionality-on-the-side hee hee :)
had to fix the svc_io_q_start_service() code which was missing the
ptr_argv[] array in between the array-size and the UNISTR2-array.
i.e it's actually an array of _pointers_ to unicode strings...
implementation (NT5) when you discover that your code is trash.
samr_enum_dom_users(), samr_enum_dom_aliases() and samr_enum_dom_groups()
all take a HANDLE for multiple-call enumeration purposes.
samr_lookup_rids() moved to a dynamic memory structure not a
static one limited to 32 RIDs. cli_pipe.c reading wasn't checking
ERRmoredata when DOS error codes negotiated (this terminates
MSRPC code with prejudice).
this format is what i would like _all_ these functions to be
(returning status codes, not BOOL) but that's a horrendous
amount of work at the moment :)
the whole task is not complete, yet. xxx_io_xxx() routines that
_call_ xxx_io_xxx() routines not done.
prs_xxxx() covered by macros. considering doing xxx_io_xxxx in the same way.
a problem i was having.
- added rudimentary CAP_STATUS32 support for same reason.
- added hard-coded, copy-the-same-data-from-over-the-wire version of
CAP_EXTENDED_SECURITY, which is a security-blob to encapsulate
GSSAPI which encodes
SPNEGO which is used to negotiate
Kerberos or NTLMSSP. i have implemented
NTLMSSP which negotiates
NTLMv1 or NTLMv2 and 40-bit or 128-bit etc. i have implemented
NTLMv1 / 40-bit.
*whew*.
simplest method to get rpcclient's reggetsec command working. the
buffers passed as arguments in do_reg_get_key_sec() do need to be
locally allocated not dynamically allocated, as two calls to
reg_get_key_sec() are needed. on the first, the server fills in the
size of the security descriptor buffer needed. on the second, the
server fills in the security descriptor buffer.
- getjob (level 1 and 2) done.
- better handling of getprinterdriver (level 2).
- added workaround to print PCL files.
Now the spoolss code should be compliant with all kind of printers :-)

* Added SEC_CHAN_BDC
* Propagate sec_chan into the various functions which change trust account
passwords, so they can be used for domain control and inter-domain
trusts.
* Fix for endianness problem reported by Edan Idzerda <edan@mtu.edu>. A
BUFFER2 is really a "unibuf" in my terminology and we should treat it as
such.
* Added some more common NT structures (BIGINT, BUFHDR2, BUFFER4).
* Added NET_SAM_SYNC (-> NetDatabaseSync2) RPC for account replication.
Still experimental and incomplete, with a few too many NULL security
descriptors lying around (must go look at Jeremy's SD code). Haven't
worked out password encryption yet either.
However, the XXX_INFO structures I've added to rpc_netlogon.h are quite
nice as they give some insight into how these objects are stored in the
SAM.
----------------------------
- removed DOM_RID4
- removed SAMR_UNKNOWN_32
- added SAMR_SET_USERINFO (opcode 0x32)
- added level 0x1 to SAMR_QUERY_DOM_INFO (needed for create user)
- fixed pwdb_gethexpwd() it was failing on XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
- added mod_sam21pwd_entry()
- preparing to call mod_sam21pwd_entry()
- added "user session key" to user_struct.dc. this is md4(nt#) and is
needed to decode user's clear-text passwords in SAMR_SET_USERINFO.
- split code out in chgpasswd.c to decode 516 byte password buffers.
(-> LsarQuerySecret) on client side, including rpcclient command
"querysecret" for others to play with.
The major obstacle is working out the encryption algorithm used
for the secret value. It definitely uses the NT hash as part of the
key, and it seems the block size is 64 bits - probably DES based -
but I can't work out what's done in between. Help required.
last count (probably an ENUM / resume handle) should always be returned
even if there are no items being returned.
- got fed up of seven intendation levels in cmd_samr.c, maximum recommended
in *any* code is three! made some sub-fns instead.
* Added SAMR_LOOKUP_DOMAIN (-> SamrLookupDomainInSamServer)
* Added real SAMR_ENUM_DOM_GROUPS (corresponding to
SamrEnumerateGroupsInDomain). The existing one is just an alias for
SamrQueryDisplayInformation (see below).
* Added three extra info levels to SAMR_QUERY_DISPINFO. Info level 3 is
what was previously SAMR_ENUM_DOM_GROUPS; info levels 4 and 5 are
simple user/group list requests used by Win9x and I suspect (haven't
checked) the "low speed connection" User Manager.
* Added another two aliases for SAMR_QUERY_DISPINFO, opcodes 0x30 and
0x33. Usually the first is with info level 3 and the second 4 but there is
some overlap so indeed these should be implemented as just aliases.
* Return ERRDOS/ERRmoredata on extra data instead of
STATUS_BUFFER_OVERFLOW for Win95's benefit. On a named pipe this results
in an SMBreadX as usual.
Still need to fix SAMR_QUERY_DOMAIN_INFO which has a hard-coded number of
users and groups - which Win95 proceeds to truncate at.
No more ugly static library buffers and all functions take a destination
string length (especially unistrcpy was rather dangerous; we were only
saved by the fact that datagrams are limited in size).
also needed to use start index properly and generate next index.
both client and server code need to recognise error code 0x105
when there's not enough room to store all the users in one call.
sort this out another time.
LsaLookupNames being incorrect. this is a bit wierd: why would the
lsass.exe on the nt _client_ crash due to an LsaLookupNames response
from a samba _server_?
