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 :-).

marked read only for that user.

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.

tests on this as it's very late NY time (just wanted to get this work
into the tree). I'll test this over the weekend....
Jerry - in looking at the difference between the two trees there
seem to be some printing/ntprinting.c and registry changes we might
want to examine to try keep in sync.

(not move) to the W32X86/{2,3}/ directory. Printmig.exe
copies the driver files for all drivers to print$/W32X86
and the calls AddPrinterDriver() for each driver. If we
move the file, then adding a driver which shares a file with
a previous driver will fail.
I can now restore drivers in bulk to a Samba 3 server.
