|
|
* Some Notes on using the SCSI Decoder:
|
|
*
|
|
* The SCSI decoder has been built right now that it is invoked directly by the
|
|
* SCSI transport layers as compared to the standard mechanism of being invoked
|
|
* via a dissector chain. There are multiple reasons for this:
|
|
* - The SCSI CDB is typically embedded inside the transport along with other
|
|
* header fields that have nothing to do with SCSI. So, it is required to be
|
|
* invoked on a embedded subset of the packet.
|
|
* - Originally, Ethereal couldn't do filtering on protocol trees that were not
|
|
* on the top level.
|
|
*
|
|
* There are four main routines that are provided:
|
|
* o dissect_scsi_cdb - invoked on receiving a SCSI Command
|
|
* void dissect_scsi_cdb (tvbuff_t *, packet_info *, proto_tree *, guint,
|
|
* guint);
|
|
* o dissect_scsi_payload - invoked to decode SCSI responses
|
|
* void dissect_scsi_payload (tvbuff_t *, packet_info *, proto_tree *, guint,
|
|
* gboolean, guint32);
|
|
* The final parameter is the length of the response field that is negotiated
|
|
* as part of the SCSI transport layer. If this is not tracked by the
|
|
* transport, it can be set to 0.
|
|
* o dissect_scsi_rsp - invoked to destroy the data structures associated with a
|
|
* SCSI task.
|
|
* void dissect_scsi_rsp (tvbuff_t *, packet_info *, proto_tree *);
|
|
* o dissect_scsi_snsinfo - invoked to decode the sense data provided in case of
|
|
* an error.
|
|
* void dissect_scsi_snsinfo (tvbuff_t *, packet_info *, proto_tree *, guint,
|
|
* guint);
|
|
*
|
|
* In addition to this, the other requirement made from the transport is to
|
|
* provide a unique way to determine a SCSI task. In Fibre Channel networks,
|
|
* this is the exchange ID pair alongwith the source/destination addresses; in
|
|
* iSCSI it is the initiator task tag along with the src/dst address and port
|
|
* numbers. This is to be provided to the SCSI decoder via the private_data
|
|
* field in the packet_info data structure. The private_data field is treated
|
|
* as a pointer to a "scsi_task_id_t" structure, containing a conversation
|
|
* ID (a number uniquely identifying a conversation between a particular
|
|
* initiator and target, e.g. between two Fibre Channel addresses or between
|
|
* two TCP address/port pairs for iSCSI or NDMP) and a task ID (a number
|
|
* uniquely identifying a task within that conversation).
|
|
*
|
|
* This decoder attempts to track the type of SCSI device based on the response
|
|
* to the Inquiry command. If the trace does not contain an Inquiry command,
|
|
* the decoding of the commands is done as per a user preference. Currently,
|
|
* only SBC (disks) and SSC (tapes) are the alternatives offered. The basic
|
|
* SCSI command set (SPC-2/3) is decoded for all SCSI devices. If there is a
|
|
* mixture of devices in the trace, some with Inquiry response and some
|
|
* without, the user preference is used only for those devices whose type the
|
|
* decoder has not been able to determine.
