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. * */ #ifdef HAVE_CONFIG_H # include "config.h" #endif #ifdef HAVE_SYS_TYPES_H # include #endif #include #include #include #include #include "prefs.h" #include "packet-scsi.h" static int proto_scsi = -1;
