it needs the specific error message.
Make messages.c return NTSTATUS and specificially NT_STATUS_INVALID_HANDLE if
sending to a non-existent process.

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.

per type - this is all we use right now and makes
re-entrancy problems with deleting handlers with
a message dispatch loop go away.

in tdb message processing. If we're inside a dispatch
function and we delete our own handler we'd walk onto
the next pointer from a deleted memory block. Fixes
crash bug in winbindd (and goodness knows where else).

become_root_uid_only()
operation
unbecome_root_uid_only()
saving errno across the second call. Most of our internal
change calls can be replaced with these simple calls.

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).

might be
a big relief on messages.tdb contention as ignoring processes with >1000
messages in printing/notify.c should work correctly now.
Jeremy, Jerry told me to ask you about printer scalability torture tests, this
might be a reason why you implemented the message_send_pid_with_timeout
using the signal (shudder) in the first place. :-)
While looking at that... Wouldn't it be better to not use the signal but have
an overall timeout for print_notify_send_messages using GetTimeOfDay & friends
and not use the alarm signal deep inside tdb.c?

than reading/re-writing one at a time. NOTE: All dispatch routines *must*
be able to cope with incoming message on *odd* byte boundaries (all current
handlers do).

pid. This follows a bug in rsync where it would accidentally
kill(-1), removing all the user's processes. I can't see any way this
would directly happen in Samba, but having the assertions seems
beneficial.

this is needed because W2K will send a TCP reset to any open
connections that have not done a negprot when a second connection is
made. This meant that under heavy netlogon load a Samba domain member
would fail authentications.
