preparation for the full share modes and ntcreatex code that I am working on. highlights include: - changed the way a backend determines if it is allowed to process a request asynchronously. The previous method of looking at the send_fn caused problems when an intermediate ntvfs module disabled it, and the caller then wanted to finished processing using this function. The new method is a REQ_CONTROL_MAY_ASYNC flag in req->control_flags, which is also a bit easier to read - fixed 2 bugs in the readbraw server code. One related to trying to answer a readbraw with smb signing (which can't work, and crashed our signing code), the second related to error handling, which attempted to send a normal SMB error packet, when readbraw must send a 0 read reply (as it has no header) - added several more ntvfs_generic.c generic mapping functions. This means that backends no longer need to implement such esoteric functions as SMBwriteunlock() if they don't want to. The backend can just request the mapping layer turn it into a write followed by an unlock. This makes the backends considerably simpler as they only need to implement one style of each function for lock, read, write, open etc, rather than the full host of functions that SMB provides. A backend can still choose to implement them individually, of course, and the CIFS backend does that. - simplified the generic structures to make them identical to the principal call for several common SMB calls (such as RAW_WRITE_GENERIC now being an alias for RAW_WRITE_WRITEX). - started rewriting the pvfs_open() code in preparation for the full ntcreatex semantics. - in pvfs_open and ipc_open, initially allocate the open file structure as a child of the request, so on error we don't need to clean up. Then when we are going to succeed the open steal the pointer into the long term backend context. This makes for much simpler error handling (and fixes some bugs) - use a destructor in the ipc backend to make sure that everthing is cleaned up on receive error conditions. - switched the ipc backend to using idtree for fnum allocation - in the ntvfs_generic mapping routines, use a allocated secondary structure not a stack structure to ensure the request pointer remains valid even if the backend replies async.
