fc8f858c8c s4: messaging: When talloc_free()'ing an event context, only remove msg_dgm_ref's that point to *that* context.
Defensive programming change. Not strictly needed to prevent
any crash/error.

Ensure it is called from process_standard.c after
every fork().

cfce21281a s4/messaging: messaging_dgm_ref talloc hierarchy fix
Ensure the messaging dgm context goes away *before* the tevent
context. The messaging dgm context will likely have active fd or timer
events, their rundown will touch the associated tevent context.

Otoh, I deliberately don't free the imessaging context here, that's going
to happen as part of freeing the talloc_autofree_context() as before. I
think it suffers the same problem, eg imessaging_deregister() works on
an imessaging_context that might already be freed. But as it works,
don't change it.

da47e13323 s4: messaging: Remove bool auto_remove parameter from imessaging_init().
With modern messaging this doesn't do anything (it's an
empty destructor). Clean up so we can add a proper destructor
in future.

2d21fe079f s4-messaging: fixed the removal of messaging sockets in child tasks
when a child task exits we were firing a destructor on any inherited
messaging contexts, which could trigger a removal of the parents
message socket and messaging database entry.

This adds a new auto_remove flag to imessaging_init(), and exposes the
cleanup code for use by the stream service.

When one of our core tasks fails to initialise it can now ask for the

c8610144f7 r15049: for really efficient oplock handling with thousands of open files we
will need a separate messaging endpoint per open file. To make this
efficient extend the messaging layer to have a new registration
function for temporary message types that maps via an idtree.

I have updated the LOCAL-MESSAGING test to use the new function.
