| | | | | | | | | Now that we transmit the level we want to break to via the msg.op_type we can unify MSG_SMB_BREAK_REQUEST and MSG_SMB_ASYNC_LEVEL2_BREAK and thus simplify the code a bit. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>
* smbd: Fix raw.batch.exclusive[59]Volker Lendecke2013-10-231-4/+6
| | | | | | | | | | | | | | | The level we have to break to depend on the breakers create_disposition: If we overwrite, we have to break to none. This patch overloads the "op_type" field in the break message we send across to the smbd holding the oplock with the oplock level we want to break to. Because it depends on the create_disposition in the breaking open, only the breaker can make that decision. We might want to use a different mechanism for this in the future, but for now using the op_type field seems acceptable to me.

| | | | | | | | | | | | | | | This flag existed to break an exclusive or batch oplock in just one instead of two steps down to "no oplock" when we did an allocation or file size change. Running raw.oplock against W2k12 differs in this respect from W2k3: W2k12 takes two steps (via level2) to break to none. This removes the special flag that we only had for compatibility with systems older than W2k12...
