target/sbc: Add DIF TYPE1+TYPE3 read/write verify emulation This patch adds support for DIF read/write verify emulation for TARGET_DIF_TYPE1_PROT + TARGET_DIF_TYPE3_PROT operation. This includes sbc_dif_verify_write() + sbc_dif_verify_read() calls accessable by backend drivers to perform DIF verify for SGL based data and protection information. Also included is sbc_dif_copy_prot() logic to copy protection information to/from backend provided protection SGLs. Based on scsi_debug.c DIF TYPE1+TYPE3 emulation. v2 changes: - Select CRC_T10DIF for TARGET_CORE in Kconfig (Fengguang) - Drop IP checksum logic from sbc_dif_v1_verify (MKP) - Fix offset on app_tag = 0xffff in sbc_dif_verify_read() Cc: Martin K.

target: Add a user-passthrough backstore Add a LIO storage engine that presents commands to userspace for execution. This would allow more complex backstores to be implemented out-of-kernel, and also make experimentation a-la FUSE (but at the SCSI level -- "SUSE"?) possible. It uses a mmap()able UIO device per LUN to share a command ring and data area. The commands are raw SCSI CDBs and iovs for in/out data. The command ring is also reused for returning scsi command status and optional sense data. This implementation is based on Shaohua Li's earlier version but heavily modified. Differences include: * Shared memory allocated by kernel, not locked-down user pages * Single ring for command request and response * Offsets instead of embedded pointers * Generic SCSI CDB passthrough instead of per-cmd specialization in ring format. * Uses UIO device instead of anon_file passed in mailbox. * Optional in-kernel handling of some commands. The main reason for these differences is to permit greater resiliency if the user process dies or hangs. Things not yet implemented (on purpose): * Zero copy. The data area is flexible enough to allow page flipping or backend-allocated pages to be used by fabrics, but it's not clear these are performance wins. Can come later. * Out-of-order command completion by userspace. Possible to add by just allowing userspace to change cmd_id in rsp cmd entries, but currently not supported. * No locks between kernel cmd submission and completion routines. Sounds like it's possible, but this can come later. * Sparse allocation of mmaped area. Current code vmallocs the whole thing. If the mapped area was larger and not fully mapped then the driver would have more freedom to change cmd and data area sizes based on demand. Current code open issues: * The use of idrs may be overkill -- we maybe can replace them with a simple counter to generate cmd_ids, and a hash table to get a cmd_id's associated pointer. * Use of a free-running counter for cmd ring instead of explicit modulo math. This would require power-of-2 cmd ring size. (Add kconfig depends NET - Randy) Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

[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.
