2002-01-20Kill off another ugly wart from the side of the passdb subsystem.Andrew Bartlett1-0/+11
This time its the pdb_getsampwuid() function - which was only being used by the SAMR rpc subsystem to gain a 'user session key'. This 'user session key' is actually generated at login time, and the other changes here simply move that data around. This also means that (when I check some details) we will be able to use the user session key, even when we are not actually the DC, becouse its one of the components of the info3 struct returned on logon. Andrew Bartlett (This used to be commit 799ac01fe08a338e4e94289f5d6767ebf905c1fa)
2002-01-20This is the current patch from Luke Leighton <lckl@samba-tng.org> to add aAndrew Bartlett1-57/+207
degree of seperation betwen reading/writing the raw NamedPipe SMB packets and the matching operations inside smbd's RPC components. This patch is designed for no change in behaviour, and my tests hold that to be true. This patch does however allow for the future loadable modules interface to specify function pointers in replacement of the fixed state. The pipes_struct has been split into two peices, with smb_np_struct taking the information that should be generic to where the data ends up. Some other minor changes are made: we get another small helper function in util_sock.c and some of the original code has better failure debugs and variable use. (As per on-list comments).

2001-03-11Ensure we're checking for the "FIRST" flag in other types of PDU than "REQUEST"Jeremy Allison1-4/+6
(ie. BIND, BINDRESP and ALTERCONTEXT) - if we don't do this then we don't set the endianness flag correctly for these PDU's. Herb - this should fix the bug you reported to me today. Jeremy. (This used to be commit dde795154cdc33cb8d6f0dfe9ae2712f7f8be3a7)
2001-03-11Merge of new 2.2 code into HEAD (Gerald I hate you :-) :-). Allows new SAMRJeremy Allison1-20/+41
RPC code to merge with new passdb code. Currently rpcclient doesn't compile. I'm working on it... Jeremy. (This used to be commit 0be41d5158ea4e645e93e8cd30617c038416e549)
2001-03-09Serious (and I *mean* serious) attempt to fix little/bigendian RPC issues.Jeremy Allison1-13/+49
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)
2001-03-03Roll back to using malloc/realloc on some of spoolss in head.Jeremy Allison1-2/+2
I'm having problems with talloc_realloc in the 2.2 branch and I want a stable reference. The only problem is this breaks the clean auto-generated code in *one* call in srv_spoolss.c (the rfnpcnex call). Jeremy. (This used to be commit 57a9340cbafa40f3a41e6c676c6f2477855fd799)
2001-02-27Added total memory allocated counter to talloc, so we can tell if a tallocJeremy Allison1-12/+24
pool is getting bloated. Also added a talloc_zero function to return zeroed memory. Added debug in rpc_server/srv_pipe_hnd.c so we know when a talloc pool is being freed. Syncup with srv_pipe_hnd.c from 2.2 so we are freeing memory at the same time. Jeremy. (This used to be commit d3a56c6042acf037bbd53de88d7636a5803ead20)
2000-08-04Fixed up the user/group contexts when using authenticated pipes.Jeremy Allison1-0/+3
Added a become_root()/unbecome_root() (push/pop security context) around the initgroups() call to ensure it would succeed. Hmmm - I wonder if this call being done as non-root might explain any "group access" bugs we've had in the past.... Jeremy. (This used to be commit 06a65972e872f37d88b84f22ea714feebd38f6c0)
2000-08-01Tidyup removing many of the 0xC0000000 | NT_STATUS_XXX stuff (only need ↵Jeremy Allison1-12/+1
NT_STATUS_XXX). Removed IS_BITS_xxx macros as they were just reproducing "C" syntax in a more obscure way. Jeremy. (This used to be commit c55bcec817f47d6162466b193d533c877194124a)
2000-07-27Ok - this is a *BIG* change - but it fixes the problems with static stringsJeremy Allison1-164/+46
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)
2000-07-03Some more sec_ctx changes. Modified some fields in the pipe_structTim Potter1-2/+8
structure so authenticated pipe users can have their unix groups set when become_authenticated_pipe_user() is called. (This used to be commit 55c9bf124dc661df43bfe582ef14b1297aeaf0fa)
2000-06-23Removed save directory argument to become_root() calls. Probably most ofTim Potter1-2/+2
this stuff doesn't need to be done as root anyway. (This used to be commit c3cad0ff6482784f95fd54ba51ee5be2354bb95d)
2000-05-26Fixed memory leak in RPC parsing code.Shirish Kalele1-1/+6
Problem in prs_set_buffer_size() was Realloc returns a NULL when newsize is zero (equivalent to a free()). We were returning a failure here without resetting the buffer_size or the data_p pointer in the prs_struct. And we weren't checking for a failure from prs_set_buffer_size(). So realloc's to zero size were not reflected in the prs_struct: memory leak. (This used to be commit 590d9ece8449b1feecfe1aa13e61bcd8fea4e5bf)
2000-05-17Fixed bug I introduced last night (sorry). Now truncate incoming prs_structJeremy Allison1-0/+7
buffer size to exact size of incoming data to prevent read overruns into slop space. Jeremy. (This used to be commit aa1a4f46da9584240cd6cee6fb652aa73e77015c)

userdom_struct. As the name implies this also contains a domain (unused at the moment). This will be important shortly, as operation in appliance mode needs the domain to be always carried with the username. (This used to be commit ee8546342d5be90e730372b985710d764564b124)

2000-01-11modified smbd/msrpc credential transfer system. user session keyLuke Leighton1-0/+10
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?

1999-12-12final part of "first" phase converting over to msrpc daemon architecture.Luke Leighton1-7/+7
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. (This used to be commit caa50525220b0d0250fa139367593c2de2c12135)
1999-12-12delineation between smb and msrpc more marked. smbd now constructsLuke Leighton1-38/+73
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()...) (This used to be commit aa3c659a8dba0437c17c60055a6ed30fdfecdb6d)
1999-12-06the first independent msrpc daemon - lsarpcd.Luke Leighton1-0/+25
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!!!

1999-03-25SAM database "set user info".Luke Leighton1-1/+1
---------------------------- - 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.
