Make 2 important changes. pdb_get_methods()
returning NULL is a *fatal* error. Don't try
and cope with it just call smb_panic. This
removes a *lot* of pointless "if (!pdb)" handling
code. Secondly, ensure that if samu_init()
fails we *always* back out of a function. That
way we are never in a situation where the pdb_XXX()
functions need to start with a "if (sampass)"
test - this was just bad design, not defensive
programming.

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 :-).

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......
of the Samba4 timezone handling code back into Samba3.
Gets rid of "kludge-gmt" and removes the effectiveness
of the parameter "time offset" (I can add this back
in very easily if needed) - it's no longer being
looked at. I'm hoping this will fix the problems people
have been having with DST transitions. I'll start comprehensive
testing tomorrow, but for now all modifications are done.
Splits time get/set functions into srv_XXX and cli_XXX
as they need to look at different timezone offsets.
Get rid of much of the "efficiency" cruft that was
added to Samba back in the day when the C library
timezone handling functions were slow.
Jeremy.
This allows the ldap-backend to search much more effeciently. Machines
will be searched in the ldap_machine_suffix and users in the
ldap_users_suffix. (Note that we already use the ldap_group_suffix in
ldapsam_setsamgrent for quite some time).
Using the specific ldap-bases becomes notably important in large
domains: On my testmachine "net rpc trustdom list" has to search through
40k accounts just to list 3 interdomain-trust-accounts, similiar effects
show up the non-user query_dispinfo-calls, etc.
Also renamed all_machines to only_machines in load_sampwd_entries()
since that reflects better what is really meant.

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
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.
cache the printer_info_2 with the open printer handle.
cache is invalidated on a mod_a_printer() call **on that smbd**.
Yes, this means that the window for admins to step on each other
from different clients just got larger, but since handles a generally
short lived this is probably ok.
- const for PACKS() in lanman.c
- change auth to 'account before password'
- add help to net rpc {vampire,samsync}
- configure updates for sun workshop cc
- become_root() around pdb_ calls in auth_util for guest login.
Andrew Bartlett
The work here includes:
- metze' set/changed patch, which avoids making changes to ldap on unmodified
attributes.
- volker's group mapping in passdb patch
- volker's samsync stuff
- volkers SAMR changes.
- mezte's connection caching patch
- my recent changes (fix magic root check, ldap ssl)
