target: add a parse_cdb method to the backend drivers Instead of trying to handle all SCSI command sets in one function (transport_generic_cmd_sequencer) call out to the backend driver to perform this functionality. For pSCSI a copy of the existing code is used, but for all virtual backends we can use a new parse_sbc_cdb helper is used to provide a simple SBC emulation. For now this setups means a fair amount of duplication between pSCSI and the SBC library, but patches later in this series will sort out that problem.

target: Add support for EXTENDED_COPY copy offload emulation This patch adds support for EXTENDED_COPY emulation from SPC-3, that enables full copy offload target support within both a single virtual backend device, and across multiple virtual backend devices. It also functions independent of target fabric, and supports copy offload across multiple target fabric ports. This implemenation supports both EXTENDED_COPY PUSH and PULL models of operation, so the actual CDB may be received on either source or desination logical unit. For Target Descriptors, it currently supports the NAA IEEE Registered Extended designator (type 0xe4), which allows the reference of target ports to occur independent of fabric type using EVPD 0x83 WWNs. For Segment Descriptors, it currently supports copy from block to block (0x02) mode. It also honors any present SCSI reservations of the destination target port. Note that only Supports No List Identifier (SNLID=1) mode is supported. Also included is basic RECEIVE_COPY_RESULTS with service action type OPERATING PARAMETERS (0x03) required for SNLID=1 operation. v3 changes: - Fix incorrect return type in target_do_receive_copy_results() (Fengguang) v2 changes: - Use target_alloc_sgl() instead of transport_generic_get_mem() - Convert debug output to use pr_debug() - Convert target_xcopy_parse_target_descriptors() NAA IEEN WWN dump to use 0x%16phN format specification - Drop unnecessary xcopy_pt_cmd->xpt_passthrough_wsem, and associated usage in xcopy_pt_write_pending() and target_xcopy_issue_pt_cmd() - Add check for unsupported EXTENDED_COPY(LID4) service action bits in target_do_xcopy() Cc: Christoph Hellwig <hch@lst.de> Cc: Hannes Reinecke <hare@suse.de> Cc: Martin Petersen <martin.petersen@oracle.com> Cc: Chris Mason <chris.mason@fusionio.com> Cc: Roland Dreier <roland@purestorage.com> Cc: Zach Brown <zab@redhat.com> Cc: James Bottomley <JBottomley@Parallels.com> Cc: Nicholas Bellinger <nab@linux-iscsi.org> Signed-off-by: Nicholas Bellinger <nab@daterainc.com>

[SCSI] tcm_loop: Add multi-fabric Linux/SCSI LLD fabric module This patch adds the TCM_Loop Linux/SCSI LLD fabric module for accessing TCM device backstores as locally accessable SCSI LUNs in virtual SAS, FC, and iSCSI Target ports using the generic fabric TransportID and Target Port WWN naming handlers from TCM's target_core_fabric_lib.c The TCM_Loop module uses the generic fabric configfs infratructure provided by target_core_fabric_configfs.c and adds a module dependent attribute for the creation/release of the virtual I_T Nexus connected the TCM_Loop Target and Initiator Ports. TCM_Loop can also be used with scsi-generic and BSG drivers so that STGT userspace fabric modules, QEMU-KVM and other hypervisor SCSI passthrough support can access TCM device backstore and control CDB emulation.

[SCSI] tcm_fc: Adding FC_FC4 provider (tcm_fc) for FCoE target (TCM - target core) support This is a comprehensive patch for FC-FC4 provider. tcm_fc is a FC-FC4 provider which glues target core (TCM) with Fiber channel library (libfc). tcm_fc uses existing FC4 provider hooks from Fiber channel library. This Fiber channel library is used by FCoE (transport - FC over Ethernet) protocol driver as well. Combination of modules such as Fiber channel library, tcm_fc, TCM target core, and FCoE protocol driver enables functional FCoE target. This patch includes initial commit for tcm_fc plus additional enhancement, bug fixes. This tcm_fc module essentially contains 3 entry points such as "prli", "prlo", "recv". When process login request (ELS_PRLI) request is received, Fiber channel library (libfc) module calls passive providers (FC-FC4, tcm_fc) (if any registered) "prli" function. Likewise when LOGO request is received, "prlo" function of passive provider is invoked by libfc. For all other request (e.g. any read/write, task management, LUN inquiry commands), "recv" function of passiver provider is invoked by libfc. Those passive providers "prli, prlo, recv" functions interact with TCM target core for requested operation. This module was primarily developed by "Joe Eykholt" and there were significant contributions from the people listed under signed-off.
