talloc_free()'ed at the end of a session. Rework the passwd cache code to use talloc_unlink and talloc_reference, to more carefully manage the cache. Andrew Bartlett (This used to be commit e3e0ec25e67308de314aa61852905ee42aa2c8fe)
2007-10-10r21460: Fix for server-side processing of SPNEGO authJeremy Allison1-0/+1
fragmented into "max xmit" size security blob chunks. Bug #4400. Needs limits adding, and also a client-side version. Jeremy. (This used to be commit aa69f2481aafee5dccc3783b8a6e23ca4eb0dbfa)
2007-10-10r21128: Fix Vista connecting to Samba in share level security.Jeremy Allison1-0/+25
Vista sends the NTLMv2 blob by default in the tconX packet. Make sure we save off the workgroup the user was logged into on the client in the sessionsetupX and re-use it for the NTLMv2 calc. Jeremy. (This used to be commit 45dcf62960c2815c4d8e0c5f4a2d0af24df83290)

2007-10-10r15589: While trying to understand the vuid code I found that security=share ↵Volker Lendecke1-3/+2
is broken right now. r14112 broke it, in 3.0.22 register_vuid for security=share returns UID_FIELD_INVALID which in current 3_0 is turned into an error condition. This makes sure that we only call register_vuid if sec!=share and meanwhile also fixes a little memleak. Then I also found a crash in smbclient with sec=share and hostmsdfs=yes. There's another crash with sec=share when coming from w2k3, but I need sleep now. Someone (jerry,jra?) please review the sesssetup.c change. Thanks, Volker (This used to be commit 8059d0ae395604503cad3d9f197928305923e3f5)

2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-1/+1
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)

2004-03-27Merge from HEAD the SMB signing patch that I developed a couple of weeksAndrew Bartlett1-1/+1
ago. This patch re-adds support for 'optional' SMB signing. It also ensures that we are much more careful about when we enable signing, particularly with on-the-fly smb.conf reloads. The client code will now attempt to use smb signing by default, and disable it if the server doesn't correctly support it.

2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-4/+19
- NTLM2 support in the server - KEY_EXCH support in the server - variable length session keys. In detail: - NTLM2 is an extension of NTLMv1, that is compatible with existing domain controllers (unlike NTLMv2, which requires a DC upgrade). * This is known as 'NTLMv2 session security' * (This is not yet implemented on the RPC pipes however, so there may well still be issues for PDC setups, particuarly around password changes. We do not fully understand the sign/seal implications of NTLM2 on RPC pipes.) This requires modifications to our authentication subsystem, as we must handle the 'challege' input into the challenge-response algorithm being changed. This also needs to be turned off for 'security=server', which does not support this. - KEY_EXCH is another 'security' mechanism, whereby the session key actually used by the server is sent by the client, rather than being the shared-secret directly or indirectly. - As both these methods change the session key, the auth subsystem needed to be changed, to 'override' session keys provided by the backend. - There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation. - The 'names blob' in NTLMSSP is always in unicode - never in ascii. Don't make an ascii version ever. - The other big change is to allow variable length session keys. We have always assumed that session keys are 16 bytes long - and padded to this length if shorter. However, Kerberos session keys are 8 bytes long, when the krb5 login uses DES. * This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. * - Add better DEBUG() messages to ntlm_auth, warning administrators of misconfigurations that prevent access to the privileged pipe. This should help reduce some of the 'it just doesn't work' issues. - Fix data_blob_talloc() to behave the same way data_blob() does when passed a NULL data pointer. (just allocate) REMEMBER to make clean after this commit - I have changed plenty of data structures... (This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)

2003-05-12And finally IDMAP in 3_0Simo Sorce1-9/+2
We really need idmap_ldap to have a good solution with ldapsam, porting it from the prvious code is beeing made, the code is really simple to do so I am confident it is not a problem to commit this code in. Not committing it would have been worst. I really would have been able to finish also the group code, maybe we can put it into a followin release after 3.0.0 even if it may be an upgrade problem. The code has been tested and seem to work right, more testing is needed for corner cases. Currently winbind pdc (working only for users and not for groups) is disabled as I was not able to make a complete group code replacement that works somewhat in a week (I have a complete patch, but there are bugs) Simo.

2003-02-24Merge of server-side authentication changes to 3.0:Andrew Bartlett1-19/+40
- user_ok() and user_in_group() now take a list of groups, instead of looking for the user in the members of all groups. - The 'server_info' returned from the authentication is now kept around - in future we won't copy the sesion key, username etc, we will just referece them directly. - rhosts upgraded to use the SAM if possible, otherwise fake up based on getpwnam(). - auth_util code to deal with groups upgraded to deal with non-winbind domain members again.

2002-01-20Kill off another ugly wart from the side of the passdb subsystem.Andrew Bartlett1-0/+2
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)
2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-0/+16
Samba (ab)uses the returns from getpwnam() a lot - in particular it keeps them around for a long time - often past the next call... This adds a getpwnam_alloc and a getpwuid_alloc to the collection. These function as expected, returning a malloced structure that can be free()ed with passwd_free(&passwd). This patch also cuts down on the number of calls to getpwnam - mostly by taking advantage of the fact that the passdb interface is already case-insensiteve. With this patch most of the recursive cases have been removed (that I know of) and the problems are reduced further by not using the sys_ interface in the new code. This means that pointers to the cache won't be affected. (This is a tempoary HACK, I intend to kill the password cache entirly). The only change I'm a little worried about is the change to rpc_server/srv_samr_nt.c for private groups. In this case we are getting groups from the new group mapping DB. Do we still need to check for private groups? I've toned down the check to a case sensitve match with the new code, but we might be able to kill it entirly. I've also added a make_modifyable_passwd() function, that copies a passwd struct into the form that the old sys_getpw* code provided. As far as I can tell this is only actually used in the pass_check.c crazies, where I moved the final 'special case' for shadow passwords (out of _Get_Pwnam()). The matching case for getpwent() is dealt with already, in lib/util_getent.c Also included in here is a small change to register the [homes] share at vuid creation rather than just in one varient of the session setup. (This picks up the SPNEGO cases). The home directory is now stored on the vuid, and I am hoping this might provide a saner way to do %H substitions. TODO: Kill off remaining Get_Pwnam_Modify calls (they are not needed), change the remaining sys_getpwnam() callers to use getpwnam_alloc() and move Get_Pwnam to return an allocated struct. Andrew Bartlett (This used to be commit 1d86c7f94230bc53daebd4d2cd829da6292e05da)
2002-01-02Actually enforce the passdb API.Andrew Bartlett1-1/+1
Thou shalt not reference SAM_ACCOUNT members directly - always use pdb_get/pdb_set. This is achived by making the whole of SAM_ACCOUNT have a .private member, where the real members live. This caught a pile of examples, and these have beeen fixed. The pdb_get..() functions are 'const' (have been for some time) and this required a few small changes to constify other functions. I've also added some debugs to the pdb get and set, they can be removed if requested. I've rewritten the copy_id2x_to_sam_pass() functions to use the new passdb interface, but I need the flags info to do it properly. The pdb_free_sam() funciton now blanks out the LM and NT hashes, and as such I have removed many extra 'samr_clear_sam_passwd(smbpass)' calls as a result. Finally, any and all testing is always appriciated - but the basics seem to work. Andrew Bartlett (This used to be commit d3dd28f6c443187b8d820d5a39c7c5b3be2fa95c)
