Compiled it on systems with and without LDAP, I hope it does not break the
build farm too badly. If it does, I'll fix it tomorrow.

we want to walk more printing code in the build farm I think doing that with a
customized printing backend is much easier than with a set of shell scripts.
Jerry, comments?

fix the messaging code to call the efficient calls :
save_re_uid()
set_effective_uid(0);
messaging_op
restore_re_uid();
instead of using heavyweight become_root()/unbecome_root()
pairs around all messaging code. Fixup the messaging
code to ensure sec_init() is called (only once) so that non-root
processes still work when sending messages.
This is a lighter weight solution to become_root()/unbecome_root()
(which swaps all the supplemental groups) and should be more
efficient. I will migrate all server code over to using this
(a similar technique should be used in the passdb backend
where needed).

examining Klockwork #1519. get_printer_subkeys()
could return zero without initializing it's return
pointer arg. Fixed this. Added free of subkey pointer
return in registry/reg_printing.c (interesting that
neithe Coverity or Klocwork found this one).

The motivating factor is to not require more privileges for
the user account than Windows does when joining a domain.
The points of interest are
* net_ads_join() uses same rpc mechanisms as net_rpc_join()
* Enable CLDAP queries for filling in the majority of the
ADS_STRUCT->config information
* Remove ldap_initialized() from sam/idmap_ad.c and
libads/ldap.c
* Remove some unnecessary fields from ADS_STRUCT
* Manually set the dNSHostName and servicePrincipalName attribute
using the machine account after the join
Thanks to Guenther and Simo for the review.
Still to do:
* Fix the userAccountControl for DES only systems
* Set the userPrincipalName in order to support things like
'kinit -k' (although we might be able to just use the sAMAccountName
instead)
* Re-add support for pre-creating the machine account in
a specific OU

is produced when a process exits abnormally.
First, we coalesce the core dumping code so that we greatly improve our
odds of being able to produce a core file, even in the case of a memory
fault. I've removed duplicates of dump_core() and split it in two to
reduce the amount of work needed to actually do the dump.
Second, we refactor the exit_server code path to always log an explanation
and a stack trace. My goal is to always produce enough log information
for us to be able to explain any server exit, though there is a risk
that this could produce too much log information on a flaky network.
Finally, smbcontrol has gained a smbd fault injection operation to test
the changes above. This is only enabled for developer builds.

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 :-).

code relied upon file permissions alone. Now we check that
the user is a printer administrator and that the share has not been
marked read only for that user.

only tell at parse time from the wire if an incoming name
has wildcards or not. If it's a mangled name and we demangle
the demangled name may contain wildcard characters. Ensure
these are ignored.

the new talloc() features:
Note that the REGSUB_CTR and REGVAL_CTR objects *must* be talloc()'d
since the methods use the object pointer as the talloc context for
internal private data.
There is no longer a regXXX_ctr_intit() and regXXX_ctr_destroy()
pair of functions. Simply TALLOC_ZERO_P() and TALLOC_FREE() the
object.
Also had to convert the printer_info_2->NT_PRINTER_DATA field
to be talloc()'d as well. This is just a stop on the road to
cleaning up the printer memory management.
