The point is doing the following associations:
- non discardable state data (all TDB files that may need to be backed
up) go to statedir
- shared data (codepage stuff) go to codepagedir
The patch *does not change* the default location for these
directories. So, there is no behaviour change when applying it.
The main change is for samba developers who have to think when dealing
with files that previously pertained to libdir whether they:
- go in statedir
- go in codepagedir
- stay in libdir

We could go one step futher and make the backend configurable. Any

more than 1000 lines of patch, but doing it in smaller pieces is hardly

Anybody interested please look over this. The patch is not really interesting,
just look at the new groupdb/mapping.c file.
Jerry, one entry for the 3.0.24 release notes: smbd will refuse to start if we
have overlapping mappings in group_mapping.tdb. With the old db a unix gid can
be mapped to two different SIDs. This will be refused with the new code.

Remove some unused code: pdb_find_alias is not used anymore, and nobody I
think has ever used the pdb_nop operations for group mapping. smbpasswd and
tdb use the default ones and ldap has its own.
Make the functions pdb_getgr* return NTSTATUS instead of BOOL. Nobody right
now really makes use of it, but it feels wrong to throw away information so
early.

a record present.
* Ensure that we distinguish between groups in the
BUILTIN and local machine domains via getgrnam()
Other wise BUILTIN\Administrators & SERVER\Administrators
would resolve to the same gid.
* Doesn't strip the global_sam_name() from groups in the
local machine's domain (this is required to work with
'winbind default domain' code)
Still todo.
* Fix fallback Administrators membership for root and domain Admins
if nested groups = no or winbindd is not running
* issues with "su - user -c 'groups'" command
* There are a few outstanding issues with BUILTIN\Users that
Windows apparently tends to assume. I worked around this
presently with a manual group mapping but I do not think
this is a good solution. So I'll probably add some similar
as I did for Administrators.
(This used to be commit 612979476a)
Not a bug in the strictest sense, more a clarification. This whole routine
assumes new_gid != NULL anyway, so there's no point in checking.
Volker
(This used to be commit dfbf09c772)
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 :-).

can be taken out of it, so I decided to commit this in one lump. It changes
the passdb enumerating functions to use ldap paged results where possible. In
particular the samr calls querydispinfo, enumdomusers and friends have
undergone significant internal changes. I have tested this extensively with
rpcclient and a bit with usrmgr.exe. More tests and the merge to trunk will
follow later.
The code is based on a first implementation by Günther Deschner, but has
evolved quite a bit since then.

following changes:
* privilege set is based on a 32-bit mask instead of strings
(plans are to extend this to a 64 or 128-bit mask before
the next 3.0.11preX release).
* Remove the privilege code from the passdb API
(replication to come later)
* Only support the minimum amount of privileges that make
sense.
* Rewrite the domain join checks to use the SeMachineAccountPrivilege
instead of the 'is a member of "Domain Admins"?' check that started
all this.
Still todo:
* Utilize the SePrintOperatorPrivilege in addition to the 'printer admin'
parameter
* Utilize the SeAddUserPrivilege for adding users and groups
* Fix some of the hard coded _lsa_*() calls
* Start work on enough of SAM replication to get privileges from one
Samba DC to another.
* Come up with some management tool for manipultaing privileges
instead of user manager since it is buggy when run on a 2k client

not exactly match what you would expect.
XP workstations during login actually do this, so we should better become a
bit more correct. The LDAP query issued is not really fully optimal, but it is
a lot faster and more correct than what was there before. The change in
passdb.h makes it possible that queryuseraliases is done with a single ldap
query.

correct anymore. If we actually open the tdb before the fork, we end up
opening the tdb twice. Jerry, jra, this also happens in the locking and
printing subsystems. You might want to check it there (not that it actually
happens right now, but this gave me some confusion lately...).
Volker

_samr_query_useraliases shows up with all kind of very weird memberships
(global-groups, machine-accounts, etc.). Sometimes even if there is no
alias-membership at all.
One of the biggest mistakes is to convert any unix-group the user is a
member of, into an alias by default in get_group_from_gid.
get_alias_user_groups should be rewritten to use
pdb_enum_alias_memberships.

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,

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

(This used to be commit e341e7c49f)
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.
(This used to be commit 0e58085978)
The intention is to remove the muliple passdb backends, but we need the
'guest' account to always be there. If the admin adds the guest account to
(say) LDAP, there will only be one backend required for operation.
This helps remove some nasty behaviours with adding accounts to the system
for both the RPC 'create user' and the SAMSYNC code. Users 'added' with
an 'add user/machine' script won't magicly appear, and machine accounts
'pre-added' to unix, but not the smbpasswd file will not cause mayhem.
This commit also implements somthing tridge discussed with me, the concept
of 'default' passdb operation pointers - so that each backend does not
need it's own stub funcitons wrapping the default tdb privilages/group
mapping code.
This also removes an implicit 'sid->name' and 'name->sid' mapping from our
own local SID space, to winbind usernames. When adding mapping for NIS/LDAP
non-sam users in future, we need to be careful.
Andrew Bartlett
(This used to be commit 6f32fa2349)
This patch makes Samba compile cleanly with -Wwrite-strings.
- That is, all string literals are marked as 'const'. These strings are
always read only, this just marks them as such for passing to other functions.
What is most supprising is that I didn't need to change more than a few lines of code (all
in 'net', which got a small cleanup of net.h and extern variables). The rest
is just adding a lot of 'const'.
As far as I can tell, I have not added any new warnings - apart from making all
of tdbutil.c's function const (so they warn for adding that const string to
struct).
Andrew Bartlett
(This used to be commit 92a777d0ea)
Currently this calls back to mapping.c, but we have the framework
to get the information into LDAP and the passdb.tdb (should we? I
think so..).
This has received moderate testing with net rpc vampire and
usrmgr. I found the add_groupmem segfault in add_aliasmem as
well, but that will be another checkin.
Volker
(This used to be commit f30095852f)
When creating a group you have to take care of the fact that the
underlying unix might not like the group name. This change gets around
that problem by giving the add group script the chance to invent a
group name. It then must only return the newly created numerical gid.

init_group_mapping() a static function and don't call it from any client
programs.
Not sure whether I've made a bigger mess here or not...
(This used to be commit 3c887d9021)
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.

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.

not the privileges. Usually we don't need them, so the memory is free
early.
lib/util_sid.c: added some helper functions to check an SID.
passdb/passdb.c: renamed local_lookup_rid() to local_lookup_sid() and pass
an RID all the way. If the group doesn't exist on the domain SID,
don't return a faked one as it can collide with a builtin one. Some rpc
structures have been badly designed, they return only rids and force the
client to do subsequent lsa_lookup_sid() on the domain sid and the builtin
sid !
rpc_server/srv_util.c: wrote a new version of get_domain_user_groups().
Only the samr code uses it atm. It uses the group mapping code instead of
a bloody hard coded crap. The netlogon code will use it too, but I have to
do some test first.

This time it's a PRIVILEGE_SET struct instead of a simple uint32 array. It
makes much more sense. Also added a uint32 systemaccount to the GROUP_MAP
struct as some privilege showing in USRMGR.EXE are not real privs but a
bitmask flag. I guess it's an heritage from NT 3.0 ! I could setup an NT
3.1 box to verify, but I'm too lazy (yes I still have my CDs).
Added 3 more LSA calls: SetSystemAccount, AddPrivileges and
RemovePrivileges, we can manage all this privilege from UserManager.
