2013-10-24smbd: Remove separate oplock_type parameter from set_file_oplockVolker Lendecke1-4/+3
This avoids the question where it could happen that something else but fsp->oplock_type might be useful as an argument here. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: David Disseldorp <ddiss@samba.org>

2013-10-23smbd: Use MSG_SMB_BREAK_REQUEST for async l2 breaksVolker Lendecke1-2/+10
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>
2013-10-23smbd: Fix raw.batch.exclusive[59]Volker Lendecke1-4/+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.

2013-10-15smbd: Inline break_level2_to_none_asyncVolker Lendecke1-38/+32
With the special case for bug 5980 in do_break_to_none we only have one caller: process_oplock_async_level2_break_message. The further goal is to merge process_oplock_async_level2_break_message with process_oplock_break_message.

2013-09-06smbd: Remove FORCE_OPLOCK_BREAK_TO_NONEVolker Lendecke1-1/+0
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...

But 8175 was fixed in a way that brlock.tdb was always locked before locking.tdb. This patch fixes the bug in a different way. locking.tdb is the central tdb for files and should always be locked first. This patch solves the problem by postponing the level2 break messages, which are async anyway.
