2001-05-04Added a SMB_ASSERT() so that two cli_state structures aren't openedTim Potter1-0/+3
on different pipes. This seriously confuses NT. Unfortunately HEAD branch is limited to one rpc pipe per connection as the fnum is stored inside the cli_state structure. It should really be broken out into it's own structure so multiple pipes can be opened on one TCP/IP socket. What a good idea! But look over here! I've already done it in another workarea but it will require a day or two to refactor some of the internal samba rpc client stuff (i.e netlogon requests) so it will remain uncommitted for another while. (This used to be commit 657804f3be2b621c8ee15bdb905879e208f9ca2f)
2001-03-09Serious (and I *mean* serious) attempt to fix little/bigendian RPC issues.Jeremy Allison1-10/+34
We were reading the endainness in the RPC header and then never propagating it to the internal parse_structs used to parse the data. Also removed the "align" argument to prs_init as it was *always* set to 4, and if needed can be set differently on a case by case basis. Now ready for AS/U testing when Herb gets it set up :-). Jeremy. (This used to be commit 0cd37c831d79a12a10e479bf4fa89ffe64c1292a)

2000-07-27Ok - this is a *BIG* change - but it fixes the problems with static stringsJeremy Allison1-9/+9
in the RPC code. This change was prompted by trying to save a long (>256) character comment in the printer properties page. The new system associates a TALLOC_CTX with the pipe struct, and frees the pool on return of a complete PDU. A global TALLOC_CTX is used for the odd buffer allocated in the BUFFERxx code, and is freed in the main loop. This code works with insure, and seems to be free of memory leaks and crashes (so far) but there are probably the occasional problem with code that uses UNISTRxx structs on the stack and expects them to contain storage without doing a init_unistrXX(). This means that rpcclient will probably be horribly broken. A TALLOC_CTX also needed associating with the struct cli_state also, to make the prs_xx code there work. The main interface change is the addition of a TALLOC_CTX to the prs_init calls - used for dynamic allocation in the prs_XXX calls. Now this is in place it should make dynamic allocation of all RPC memory on unmarshall *much* easier to fix. Jeremy. (This used to be commit 0ff2ce543ee54f7364e6d839db6d06e7ef1edcf4)

1999-12-12delineation between smb and msrpc more marked. smbd now constructsLuke Leighton1-3/+1
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()...)

1999-11-27further abstraction involving client states. main client-side codeLuke Leighton1-18/+4
is pretty much independent of SMB client states, which will make it easier to add other transports. (This used to be commit a1ff7e8fc3129ba4a04722f977bc2d3725d13624)
1999-11-25cool! completed a samr* API that _would_ look like an msdn samr* api...Luke Leighton1-0/+17
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... (This used to be commit 8ce93b80d3b4e1c1e28aa1dde38cdef184eff3c1)
1999-11-24ok. *whew*. this is the first completed part of the restructure.Luke Leighton1-6/+6
verified that lsaquery, lsalookupsids work, and found some bugs in the parameters of these commands :-) soo... we now have an lsa_* api that has the same arguments as the nt Lsa* api! cool! the only significant coding difference is the introduction of a user_credentials structure, containing user, domain, pass and ntlmssp flags. (This used to be commit 57bff6fe82d777e599d535f076efb2328ba1188b)
1999-11-24first stages of removing struct cli_state* and uint16 fnum from allLuke Leighton1-5/+8
msrpc client code. the intent is to hide / abstract / associate connection info behind policy handles. this makes the msrpc functions look more and more like their nt equivalents. who-hou! (This used to be commit c01b18e632aede6fce7264ef6971d7ddba945cfb)
1999-11-21you know what? this sort of thing makes me laugh. hmm, what functionsLuke Leighton1-1/+1
have we got. and what data do we have. hmm.. i wonder what the NTLMv2 user session key can be... hmmm... weell.... there's some hidden data here, generated from the user password that doesn't go over-the-wire, so that's _got_ to be involved. and... that bit of data took a lot of computation to produce, so it's probably _also_ involved... and md4 no, md5? no, how about hmac_md5 yes let's try that one (the other's didn't work) oh goodie, it worked! i love it when this sort of thing happens. took all of fifteen minutes to guess it. tried concatenating client and server challenges. tried concatenating _random_ bits of client and server challenges. tried md5 of the above. tried hmac_md5 of the above. eventually, it boils down to this: kr = MD4(NT#,username,domainname) hmacntchal=hmac_md5(kr, nt server challenge) sess_key = hmac_md5(kr, hmacntchal); (This used to be commit ab174759cd210fe1be888d0c589a5b2669f7ff1e)
1999-11-09debugging rpcclient spoolenum and spooljobs commands. oh, did i forgetLuke Leighton1-2/+2
to mention, there's a spooljobs <printer name> command, and it uses command-line completion? prints out NT print jobs really nicely, too. (This used to be commit e6e5caf16c8d120f0c11fa63061f2786098e3357)

1999-10-21various. debug levels changed. nmbd doesn't need libsmb/clienttrust.c.Luke Leighton1-6/+21
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 used to be commit 8976eca2db43576c32069dcda017e8777048e007)

1999-10-07- added rudimentary CAP_UNICODE support because i thought it was part ofLuke Leighton1-14/+31
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*.

rather than 0x18. Rather nasty, I doubt the client ever worked for multiple PDU's. (This used to be commit 90b6fce780c8dff37a389493be0568923b189ff0)

1998-11-17- group database API. oops and oh dear, the threat has been carried out:Luke Leighton1-1/+0
the pre-alpha "domain group" etc parameters have disappeared. - interactive debug detection - re-added mem_man (andrew's memory management, detects memory corruption) - american spellings of "initialise" replaced with english spelling of "initialise". - started on "lookup_name()" and "lookup_sid()" functions. proper ones. - moved lots of functions around. created some modules of commonly used code. e.g the password file locking code, which is used in groupfile.c and aliasfile.c and smbpass.c - moved RID_TYPE_MASK up another bit. this is really unfortunate, but there is no other "fast" way to identify users from groups from aliases. i do not believe that this code saves us anything (the multipliers) and puts us at a disadvantage (reduces the useable rid space). the designers of NT aren't silly: if they can get away with a user- interface-speed LsaLookupNames / LsaLookupSids, then so can we. i spoke with isaac at the cifs conference, the only time for example that they do a security context check is on file create. certainly not on individual file reads / writes, which would drastically hit their performance and ours, too. - renamed myworkgroup to global_sam_name, amongst other things, when used in the rpc code. there is also a global_member_name, as we are always responsible for a SAM database, the scope of which is limited by the role of the machine (e.g if a member of a workgroup, your SAM is for _local_ logins only, and its name is the name of your server. you even still have a SID. see LsaQueryInfoPolicy, levels 3 and 5). - updated functionality of groupname.c to be able to cope with names like DOMAIN\group and SERVER\alias. used this code to be able to do aliases as well as groups. this code may actually be better off being used in username mapping, too. - created a connect to serverlist function in clientgen.c and used it in password.c - initialisation in server.c depends on the role of the server. well, it does now. - rpctorture. smbtorture. EXERCISE EXTREME CAUTION. (This used to be commit 0d21e1e6090b933f396c764af535ca3388a562db)

smb.tgz file from my portable. particularly the call to mem_data followed by a realloc of that data in cli_pipe.c's rpc_read() function. smbd responses now use p->rdata_i which is a faked-up pointer into p->rdata's response data. rdata can be very long; rdata_i is limited to point to no more than max_tsize - 0x18 in length. this will make it an almost trivial task to add the encrypted rpc headers after rdata_i, and mem_buf_copy will cope admirably with rhdr chained to rdata_i chained to auth_verifier etc etc...

1998-10-15bug-fixing against:Luke Leighton1-4/+22
AS/U: it returns dce/rpc "first" and "last" bits _clear_ in a bind/ack response, when they should be set in a (small) packet. they also, in the bind/ack do not set a secondary address string at all, so we can't check against that... Win95: client-side dce/rpc code is a bit odd. it does a "WaitNamedPipeState" and has slightly different pipe-naming (\PIPE\LANMAN is joined by \PIPE\SRVSVC, \PIPE\WINREG etc whereas nt just has \PIPE\LANMAN and \PIPE\). Win95-USRMGR.EXE: added LsaOpenPolicy (renamed existing to LsaOpenPolicy2). added SamrConnect (renamed existing to SamrConnect2). (This used to be commit a7fccd807b938cbb51002ebae8c7a48b40dbb655)
