Will allow thread-specific credentials to be added by modifying the central definitions. Deliberately left the setXX[ug]id() call in popt as this is not used in Samba.

A return code of 1 from initgroups() is OK since apparently it means the gid has already been set. The man page doesn't mention this.

2007-10-10r23528: Two changes to make the valgrind massif (heap profiler) output readable:Volker Lendecke1-1/+1
Remove the allocated inbuf/output. In async I/O we copy the buffers explicitly now, so NewInBuffer is called exactly once. This does not reduce memory footprint, but removes one of the larger chunks that clobber the rest of the massif output In getgroups_unix_user on Linux 2.6 we allocated 64k groups x 4 bytes per group x 2 (once in the routine itself and once in libc) = 512k just to throw it away directly again. This reduces it do a more typical limit of 32 groups per user. We certainly cope with overflow fine if 32 is not enough. Not 100% sure about this one, a DEVELOPER only thing?

2007-10-10r20090: Fix a class of bugs found by James Peach. EnsureJeremy Allison1-4/+11
we never mix malloc and talloc'ed contexts in the add_XX_to_array() and add_XX_to_array_unique() calls. Ensure that these calls always return False on out of memory, True otherwise and always check them. Ensure that the relevent parts of the conn struct and the nt_user_tokens are TALLOC_DESTROYED not SAFE_FREE'd. James - this should fix your crash bug in both branches. Jeremy.

2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-7/+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)

2007-10-10r3705: Nobody has commented, so I'll take this as an ack...Volker Lendecke1-1/+89
abartlet, I'd like to ask you to take a severe look at this! We have solved the problem to find the global groups a user is in twice: Once in auth_util.c and another time for the corresponding samr call. The attached patch unifies these and sends them through the passdb backend (new function pdb_enum_group_memberships). Thus it gives pdb_ldap.c the chance to further optimize the corresponding call if the samba and posix accounts are unified by issuing a specialized ldap query. The parameter to activate this ldapsam behaviour is ldapsam:trusted = yes Volker (This used to be commit b94838aff1a009f8d8c2c3efd48756a5b8f3f989)

2003-06-29Here's the code to make winbindd work on a Samba DCGerald Carter1-3/+21
to handle domain trusts. Jeremy and I talked about this and it's going in as working code. It keeps winbind clean and solves the trust problem with minimal changes. To summarize, there are 2 basic cases where the deadlock would occur. (1) lookuping up secondary groups for a user, and (2) get[gr|pw]nam() calls that fall through the NSS layer because they don't exist anywhere. o To handle case #1, we bypass winbindd in sys_getgrouplist() unless the username includes the 'winbind separator'. o Case #2 is handled by adding checks in winbindd to return failure if we are a DC and the domain matches our own. This code has been tested using basic share connections, domain logons, and with pam_winbind (both with and without 'winbind use default domain'). The 'trustdomain' auth module should work as well if an admin wants to manually create UNIX users for acounts in the trusted domains. Other misc fixes: * we need to fix check_ntlm_password() to be able to determine if an auth module is authoritative over a user (NT_STATUS_WRONG_PASSWORD, etc...). I worked around my specific situation, but this needs to be fixed. the winbindd auth module was causing delays. * fix named server mutex deadlock between trust domain auth module and winbindd looking up a uid * make sure SAM_ACCOUNT gets stored in the server_info struct for the _net_sam_logon() reply. Configuration details: The recommended method for supporting trusts is to use winbind. The gets us around some of the server mutex issues as well. * set 'files winbind' for passwd: and group: in /etc/nsswitch.conf * create domain trusts like normal * join winbind on the pdc to the Samba domain using 'net rpc join' * add normal parameters to smb.conf for winbind * set 'auth method = guest sam winbind' * start smbd, nmbd, & winbindd Problems that remain: * join a Windows 2k/XP box to a Samba domain. * create a 2-way trust between the Samba domain and an NT domain * logon to the windows client as a user from theh trusted domain * try to browse server in the trusted domain (or other workstations). an NT client seems to work ok, but 2k and XP either prompt for passwords or fail with errors. apparanently this never got tested since no one has ever been able to logon as a trusted user to a Samba domain from a Windows client.
