2013-10-25Revert "smbd: Move oplock/sharemode ops into one place"Volker Lendecke1-3/+10
This reverts commit 7b70fa18734d9ceb020fe3e5d4cc0c26cd27a484. This is a change in behaviour which needs much further investigation and testing.

2013-10-24smbd: Move oplock/sharemode ops into one placeVolker Lendecke1-10/+3
This makes the is_stat_open special case in grant_fsp_oplock_type redundant because in open_file_ntcreate further up we have already set oplock_request to NO_OPLOCK for stat opens. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: David Disseldorp <ddiss@samba.org>

2013-10-23smbd: Fix raw.batch.exclusive[59]Volker Lendecke1-6/+23
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: validate oplock types even for internal and stat opensVolker Lendecke1-18/+3
There's no reason why we should not do this. This has turned into a pure internal consistency check that should apply fine every time. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>
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.

2013-10-16smbd: Reduce the complexity of open_file_ntcreateVolker Lendecke1-24/+40
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.

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...
