We now open messages.tdb even before we do the become_daemon. become_daemon()
involves a fork and an immediate exit of the parent, thus the
parent_is_longlived argument must be set to false in this case. The parent is
not really long lived :-)

doing this because for the clustering the marshalling is needed in more
than one place, so I wanted a decent routine to marshall a message_rec
struct which was not there before.
Tridge, this seems about the same speed as it used to be before, the
librpc/ndr overhead in my tests was under the noise.

This changes "struct process_id" to "struct server_id", keeping both is
just too much hassle. No functional change (I hope ;-))

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 :-).
