void message_register(int msg_type,
void (*fn)(int msg_type, struct process_id pid,
- void *buf, size_t len))
+ void *buf, size_t len,
+ void *private_data),
+ void *private_data)
{
struct dispatch_fns *dfn;
So this adds a (so far unused) private pointer that is passed from
message_register to the message handler. A prerequisite to implement a tiny
samba4-API compatible wrapper around our messaging system. That itself is
necessary for the Samba4 notify system.
Yes, I know, I could import the whole Samba4 messaging system, but I want to
do it step by step and I think getting notify in is more important in this
step.

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).

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 :-).

{become,unbecome}_root() blocks. We've already done
a print_access_check() to ensure the user is admin.
The means that non-root users can pause and manage printers.
I really don't see how this worked before without setuid
binaries on the server.
Also update print_queue_update() interface to allow an smbd
to update the print queue cache locally rather than going through
the bg lpq daemon. This is needed for things like pjob_delete()
to ensure the cache is current for the specific client.

- replaced (un)publish_it() with ads-specific functions
- moved common code to nt_printer_publish()
- improved error handling in several places
- added check_published_printers() in printing/nt_printing.c, to verify
that each published printer is actually in the directory at startup
- changed calling semantics of mod_a_printer, dump_a_printer, and
update_driver_init to be more consistent with the rest of the api and
reduce some copying

patch from Olaf Flebbe <o.flebbe@science-computing.de>.

(PRINTER_ATTRIBUTE_SAMBA)
* Resolve name conflict on DEC OSF-5.1 (inspired by patch from
Adharsh Praveen <rprav@india.hp.com>)
* Work around parsing error in the print change notify code

* remove duplicate declaration of getprintprocdir from rpcclient.

The problem was that the current_printif struct was set during
print_backend_init() based on the 'printcap name'. So you could
not use cups and then override the setting for a specific printer
by setting 'printing = bsd' (a common setup for pdf generation
print services.
There is a subtle change in behavior in that the print
interface functions are selecting on the basis of lp_printing()
and not lp_printcap_name(), but the new behavior seems more
intuitive IMHO.
