2013-07-11smbd: Fix a 100% loop at shutdown timeVolker Lendecke1-2/+5
In the destructor of fsp->aio_requests[0] we put another request into fsp->aio_requests[0]. Don't overwrite that with TALLOC_FREE.

2013-07-09smbd: Fix a profile problemVolker Lendecke5-27/+34
When trying to read a profile, under certain circumstances Windows tries to read with its machine account first. The profile previously written was stored with an ACL that only allows access for the user and not the machine. Windows should get an NT_STATUS_ACCESS_DENIED when using the machine account, making it retry with the user account (which would then succeed). Samba under these circumstances erroneously gives NT_STATUS_OBJECT_PATH_NOT_FOUND, which makes Windows give up and not retry. The reasons is the "dropbox" patch in unix_convert, turning EACCESS on the last path component to OBJECT_PATH_NOT_FOUND. This patch makes the dropbox behaviour only kick in when we are creating a file. I think this is an abstraction violation. unix_convert() should not have to know about the create_disposition, but given that we have pathname resolution separated from the core open code right now this is the best we can do.

2013-06-25s3:smbd/close remove filesystem lock before removing sharemodeChristian Ambach1-0/+9
otherwise we are open for a race condition: opener 1 opens file and closes it - during the close, the share mode entry will be removed from locking.tdb, but share mode in the file system will be dropped later after delete_on_close and write time updates have been done opener 2 requests open of same file with file overwrite - locking.tdb does not list original entry, but file system share mode is still around - VFS_FTRUNCATE will fail and error was converted to STATUS_ACCESS_DENIED Signed-off-by: Christian Ambach <ambi@samba.org> Reviewed-by: Volker Lendecke <vl@samba.org> Autobuild-User(master): Christian Ambach <ambi@samba.org> Autobuild-Date(master): Tue Jun 25 14:48:44 CEST 2013 on sn-devel-104

2013-06-03Fix bug 9900: is_printer_published GUID retrievalDavid Disseldorp1-1/+1
Samba currently always responds to GetPrinter(level = 7) requests with DSPRINT_UNPUBLISH, regardless of the AD publish status tracked via the PRINTER_ATTRIBUTE_PUBLISHED flag. This is due to erroneous "objectGUID" unmarshalling in is_printer_published(). This change splits "objectGUID" retrieval into a separate function, and adds a pull_reg_sz() call to correctly unmarshall the GUID.
