[SCSI] target: Add LIO target core v4.0.0-rc6 LIO target is a full featured in-kernel target framework with the following feature set: High-performance, non-blocking, multithreaded architecture with SIMD support. Advanced SCSI feature set: * Persistent Reservations (PRs) * Asymmetric Logical Unit Assignment (ALUA) * Protocol and intra-nexus multiplexing, load-balancing and failover (MC/S) * Full Error Recovery (ERL=0,1,2) * Active/active task migration and session continuation (ERL=2) * Thin LUN provisioning (UNMAP and WRITE_SAMExx) Multiprotocol target plugins Storage media independence: * Virtualization of all storage media; transparent mapping of IO to LUNs * No hard limits on number of LUNs per Target; maximum LUN size ~750 TB * Backstores: SATA, SAS, SCSI, BluRay, DVD, FLASH, USB, ramdisk, etc. Standards compliance: * Full compliance with IETF (RFC 3720) * Full implementation of SPC-4 PRs and ALUA Significant code cleanups done by Christoph Hellwig.

[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.
