* smbd:smb2: fix durable reconnect: set fsp->fnum from the smbXsrv_open->local_idMichael Adam2014-01-301-0/+1
| | | | | | | Originally, fsp->fnum was left at the INVALID fnum value. Signed-off-by: Michael Adam <obnox@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>
* smbd: Remove separate oplock_type parameter from set_file_oplockVolker Lendecke2013-10-241-1/+1
| | | | | | | | 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>
* smbd: Unify parameters to set_oplock_typeVolker Lendecke2013-10-241-1/+1
| | | | | | | | | | Some lines above we set fsp->oplock_type = e->op_type. I don't see how this might have changed. This change will unify both callers of set_file_oplock. In the next step the second parameter to set_file_oplock will be removed. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: David Disseldorp <ddiss@samba.org>

If any detail differs, we deny the durable reconnect, because in that case it is very likely that someone opened the file while the handle was disconnected, which has to be interpreted as an oplock break.

* s3:smbd/durable: update the low level write_time before disconnecting the file.Stefan Metzmacher2012-10-191-0/+19
| | | | | | | | | | | | | | | | | If we close the low level FD, we should better update the write_time if needed. It's not unlikely that the client doesn't reclaim the durable handle, in that case we may not close the after the durable timeout. In such a case we should make sure that we at least update the write time on disconnect, this makes sure backup applications notice that the file was changed. metze Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: Michael Adam <obnox@samba.org>

We only grant durable handles for CIFS/SMB2 only access, that means "kernel oplocks", "kernel share modes" and "posix locking" need to be set to "no". For now we also don't grant durable handles if delete on close is active on the handle. Pair-Programmed-With: Stefan Metzmacher <metze@samba.org> Pair-Programmed-With: Volker Lendecke <vl@samba.org>
