2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-0/+2
realloc can return NULL in one of two cases - (1) the realloc failed, (2) realloc succeeded but the new size requested was zero, in which case this is identical to a free() call. The error paths dealing with these two cases should be different, but mostly weren't. Secondly the standard idiom for dealing with realloc when you know the new size is non-zero is the following : tmp = realloc(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } However, there were *many* *many* places in Samba where we were using the old (broken) idiom of : p = realloc(p, size) if (!p) { return error; } which will leak the memory pointed to by p on realloc fail. This commit (hopefully) fixes all these cases by moving to a standard idiom of : p = SMB_REALLOC(p, size) if (!p) { return error; } Where if the realloc returns null due to the realloc failing or size == 0 we *guarentee* that the storage pointed to by p has been freed. This allows me to remove a lot of code that was dealing with the standard (more verbose) method that required a tmp pointer. This is almost always what you want. When a realloc fails you never usually want the old memory, you want to free it and get into your error processing asap. For the 11 remaining cases where we really do need to keep the old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR, which can be used as follows : tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the pointer p, even on size == 0 or realloc fail. All this is done by a hidden extra argument to Realloc(), BOOL free_old_on_error which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR macros (and their array counterparts). It remains to be seen what this will do to our Coverity bug count :-). Jeremy. (This used to be commit 1d710d06a214f3f1740e80e0bffd6aab44aac2b0)
2007-10-10r13590: * replace all pdb_init_sam[_talloc]() calls with samu_new()Gerald Carter1-5/+5

2007-10-10r13576: This is the beginnings of moving the SAM_ACCOUNT data structureGerald Carter1-9/+9
to make full use of the new talloc() interface. Discussed with Volker and Jeremy. * remove the internal mem_ctx and simply use the talloc() structure as the context. * replace the internal free_fn() with a talloc_destructor() function * remove the unnecessary private nested structure * rename SAM_ACCOUNT to 'struct samu' to indicate the current an upcoming changes. Groups will most likely be replaced with a 'struct samg' in the future. Note that there are now passbd API changes. And for the most part, the wrapper functions remain the same. While this code has been tested on tdb and ldap based Samba PDC's as well as Samba member servers, there are probably still some bugs. The code also needs more testing under valgrind to ensure it's not leaking memory. But it's a start...... (This used to be commit 19b7593972480540283c5bf02c02e5ecd8d2c3f0)

2007-10-10r8786: Fix amazing and long-standing bug where user-accounts are just crippledGünther Deschner1-2/+1
accounts (accounts without AcctCtrl set) after a vampire-process. New Accounts tend to hace no acb_info at all which means "0" (ACB_NORMAL). Unless 0 becomes not 0 we don't do anything and set *no* acctrl for normal users at all (!). Those crippled users now don't show up in usrmgr since 3.0.20somethings ldap-routines now finally test if the attribute is there.

2004-02-08Make more functions static, and remove duplication in the use of functionsAndrew Bartlett1-6/+6

2004-01-02JHT came up with a nasty (broken) torture case in preparing examples forAndrew Bartlett1-2/+2
his book. This prompted me to look at the code that reads the unix group list. This code did a lot of name -> uid -> name -> sid translations, which caused problems. Instead, we now do just name->sid I also cleaned up some interfaces, and client tools. Andrew Bartlett (This used to be commit f9e59f8bc06fae7e5c8cb0980947f78942dc25c0)

2003-08-07Turns out I had my packet sequences wrong for oplock break code.Jeremy Allison1-2/+6
I was storing the mid of the oplock break - I should have been storing the mid from the open. There are thus 2 types of deferred packet sequence returns - ones that increment the sequence number (returns from oplock causing opens) and ones that don't (change notify returns etc). Running with signing forced on does lead to some interesting tests :-). Jeremy. (This used to be commit 85907f02cec566502d9e4adabbd414020a26064d)

2003-07-16fixes for 'net rpc vampire'. I can now take a blank Samba hostGerald Carter1-25/+12
and migrate an NT4 domain and still logon from domain members (tested logon scripts, system policies, profiles, & home directories) (passdb backend = tdbsam) removed call to idmap_init_wellknown_sids() from winbindd.c since the local domain should be handled by the guest passdb backend (and you don't really always want the Administrator account to be root) ...and we didn't pay attention to this anyways now. (This used to be commit 837d7c54d3ca780160aa0d6a2f0a109bb691948e)
2003-07-11moving more code around.Gerald Carter1-1/+3
* move rid allocation into IDMAP. See comments in _api_samr_create_user() * add winbind delete user/group functions I'm checking this in to sync up with everyone. But I'm going to split the add a separate winbindd_allocate_rid() function for systems that have an 'add user script' but need idmap to give them a RID. Life would be so much simplier without 'enable rid algorithm'. The current RID allocation is horrible due to this one fact. Tested idmap_tdb but not idmap_ldap yet. Will do that tomorrow. Nothing has changed in the way a samba domain is represented, stored, or search in the directory so things should be ok with previous installations. going to bed now. (This used to be commit 0463045cc7ff177fab44b25faffad5bf7140244d)

down failures. Add a 'auto-add on modify' feature to guestsam Fix some segfault bugs on no-op idmap modifications, and on new idmappings that do not have a DN to tack onto. Make the 'private data' a bit more robust. Andrew Bartlett (This used to be commit 6c48309cda9538da5a32f3d88a7bb9c413ae9e8e)
2003-07-05Fixes to our LDAP/vampire codepaths:Andrew Bartlett1-37/+44
- Try better to add the appropriate mapping between UID and SIDs, based on Get_Pwnam() - Look for previous users (lookup by SID) and correctly modify the existing entry in that case - Map the root user to the Admin SID as a 'well known user' - Save the LDAPMessage result on the SAM_ACCOUNT for use in the next 'update' call on that user. This means that VL's very nice work on atomic LDAP updates now really gets used properly! - This also means that we know the right DN to update, without the extra round-trips to the server. Andrew Bartlett (This used to be commit c7118cb31dac24db3b762fe68ce655b17ea102e0)
2003-06-18Ok, this patch removes the privilege stuff we had in, unused, for some time.Simo Sorce1-10/+4
The code was nice, but put in the wrong place (group mapping) and not supported by most of the code, thus useless. We will put back most of the code when our infrastructure will be changed so that privileges actually really make sense to be set. This is a first patch of a set to enhance all our mapping code cleaness and stability towards a sane next beta for 3.0 code base Simo. (This used to be commit e341e7c49f8c17a9ee30ca3fab3aa0397c1f0c7e)
2003-06-16Make net rpc vampire return an error if the sam sync RPC returns an error.Tim Potter1-9/+29
E.g if we are pointing at a win2k native mode domain we are returned an NT_STATUS_NOT_SUPPORTED error. (This used to be commit 6053c30f26cdf60f2bbfa6fb58ced6f7bcbd2e83)
2003-06-14This patch modifies 'net rpc vampire' to add new and existing users to bothAndrew Bartlett1-20/+39
the idmap and the SAM. The basic idea is this: Lookup the user with GetPwnam(), and if they exist then use that uid. This is what people expect. If the user does not exist, try and run the right script. This is also what people expect from previous Samba 3.0 behaviour, where the Get_Pwnam() was at runtime. If the idmap entry for this SID isn't valid, or isn't the right value, modify the idmap to account for this mapping. Also, the same logic is applied to the primary gid - if it has changed, update the user's primary unix group. This patch allows users to be added without a mapping - this is fine for machine accounts, for example. I've given it a quick test against my Win2k DC, and I *think* it's sane.

2003-04-21Merge from HEAD - save the type of channel used to contact the DC.Andrew Bartlett1-4/+7
This allows us to join as a BDC, without appearing on the network as one until we have the database replicated, and the admin changes the configuration. This also change the SID retreval order from secrets.tdb, so we no longer require a 'net rpc getsid' - the sid fetch during the domain join is sufficient. Also minor fixes to 'net'.
