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 Lendecke2-10/+29
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.

2013-10-23smbd: Fix bug 10216Volker Lendecke1-4/+28
While refactoring find_oplock_types to validate_oplock_types I forgot that stat opens will end up in locking.tdb. So even with a batch oplock around we can have more than one entry. This means the consistency check in validate_oplock_types was wrong and too strict. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>

2013-10-16smbd: Remove "file_existed" handling from open_mode_checkVolker Lendecke1-12/+16
No clue what this does. In open_directory, "dir_existed" is not used after open_mode_check. In open_file_ntcreate it's used, but I can't think of a case right now where we would find a formerly nonexisting file to exist suddenly.

2013-10-16smbd: Decouple grant_fsp_oplock_type from oplock validationVolker Lendecke1-27/+26
This makes grant_fsp_oplock_type independent from the values computed in validate_oplock_types. It *might* make oplock calculation a bit slower for heavily shared files, as we are walking the share mode array twice. But we are doing so much stuff in open that I doubt the difference is measurable. It clears up the code for me however, and I think that's worth it.

This removes two variables in open_file_ntcreate based on the observation that for exclusive and batch oplocks there can only be one entry. So in these cases we don't need to keep pointers from find_oplock_types to delay_for_oplocks. We can just reference the only share mode entry around.

https://bugzilla.samba.org/show_bug.cgi?id=10208 Authentication error in smb2 session reauth invalidates the session. In this case the session must in contrast to successful session setup requests be torn down and live no longer than the request. The talloc move of the session from the global session table to the request ensures that the session setup reply can still be correctly signed, but subsequent requests on the connection don't find a session any more.
