Routine Description:
|
|
|
|
The SMB_PROCESSOR is a routine that is called to process a specific
|
|
SMB command.
|
|
|
|
Arguments:
|
|
|
|
WorkContext - Supplies the address of a Work Context Block
|
|
describing the current request. In particular, the following
|
|
fields are valid:
|
|
|
|
RequestHeader - Address of the request SMB header.
|
|
|
|
RequestParameters - Address of the current command's request
|
|
parameters. The SMB processor should update this field to
|
|
point to the next command in the SMB, if any.
|
|
|
|
ResponseHeader - Address of the response SMB header. Initially,
|
|
this is a copy of the request header. As return data, such
|
|
as UID, TID, and FID, becomes available, it should be
|
|
written into both the request header (for AndX command
|
|
processors) and the response header (for the client). Note
|
|
that the response header address *may* be the same as the
|
|
request header address.
|
|
|
|
ResponseParameters - Address of the current command's response
|
|
parameters. The SMB processor should write the response
|
|
data to this address, then update the pointer to point to
|
|
the address of the next command's response area, if any.
|
|
If there are no more commands in the SMB, this field should
|
|
be set to point to the first byte after the response so that
|
|
the length of the response can be computed.
|
|
|
|
Endpoint, Connection - Addresses of the endpoint and the
|
|
connection that received the SMB. These fields should not
|
|
be changed by the SMB processor. Other block pointers in
|
|
WorkContext (Share, Session, TreeConnect, and Rfcb) may be
|
|
set by the SMB processor if such blocks are referenced
|
|
during processing. Any non-NULL pointers in these fields
|
|
are dereferenced when SMB processing is complete, before the
|
|
response (if any) is sent. The Connection and Endpoint
|
|
pointers are not cleared until the WorkContext is requeued
|
|
to the receive queue.
|
|
|
|
Parameters - This union is used by the various SMB processors to
|
|
retain state during asynchronous operations.
|
|
|
|
Return Value:
|
|
|
|
SMB_STATUS - Indicates the action to be taken by the calling routine.
|
|
Possible values are the following:
|
|
|
|
SmbStatusMoreCommands - There is at least one more AndX
|
|
follow-on command in the request SMB. The SMB processor has
|
|
updated RequestParameters and ResponseParameters in
|
|
WorkContext to point to the next command's request and
|
|
response areas. It has also copied the command code of
|
|
the next command into RequestHeader->Command, so that
|
|
SrvProcessSmb can dispatch the next request.
|
|
|
|
SmbStatusSendResponse - Processing of the request is complete,
|
|
and a response is to be sent. ResponseParameters has been
|
|
updated to point to the first location *after* the end of
|
|
the response. This is used to compute the length of the
|
|
response.
|
|
|
|
SmbStatusNoResponse - Processing of the request is complete, but
|
|
either no response is needed or the SMB processor has
|
|
already taken care of sending the response(s).
|
|
|
|
SmbStatusInProgress - The SMB processor has started an
|
|
asynchronous operation and will continue processing the SMB
|
|
at an appropriate restart routine when the operation
|
|
completes. The restart routine, after updating WorkContext,
|
|
calls SrvSmbProcessSmb to continue (or end) processing the
|
|
SMB.

Routine Description:
|
|
|
|
The SMB_TRANSACTION_PROCESSOR is a routine that is called to process
|
|
a specific Transaction or Transaction2 SMB subfunction.
|
|
|
|
Arguments:
|
|
|
|
WorkContext - Supplies the address of a Work Context Block
|
|
describing the current request. In particular, the following
|
|
fields are valid and intended for use by the transaction
|
|
processor:
|
|
|
|
ResponseHeader - Address of the response SMB header. Initially,
|
|
this is a copy of the request header. The transaction
|
|
processor may update the error class and code fields if it
|
|
encounters an error.
|
|
|
|
Parameters.Transacton - Points to the transaction block
|
|
describing the transaction. All block pointer fields
|
|
(Connection, Session, TreeConnect) in the block are valid.
|
|
Pointers to the setup words and parameter and data bytes,
|
|
and the lengths of these items, are valid. The transaction
|
|
block is on the connection's pending transaction list.
|
|
|
|
The transaction processor must update the transaction block
|
|
to indicate how much data to return.
|
|
|
|
Return Value:
|
|
|
|
BOOLEAN - Indicates whether an error occurred. FALSE indicates that
|
|
the operation was successful, and that the data counts were
|
|
updated to indicate how much data to return. TRUE indicates
|
|
that an error occurred, and that SrvSetSmbError was called to
|
|
update the response header and place a null parameters field at
|
|
the end of the response.
