Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending Pull SCSI target updates from Nicholas Bellinger: "It's been a busy development cycle for target-core in a number of different areas. The fabric API usage for se_node_acl allocation is now within target-core code, dropping the external API callers for all fabric drivers tree-wide. There is a new conversion to RCU hlists for se_node_acl and se_portal_group LUN mappings, that turns fast-past LUN lookup into a completely lockless code-path. It also removes the original hard-coded limitation of 256 LUNs per fabric endpoint. The configfs attributes for backends can now be shared between core and driver code, allowing existing drivers to use common code while still allowing flexibility for new backend provided attributes. The highlights include: - Merge sbc_verify_dif_* into common code (sagi) - Remove iscsi-target support for obsolete IFMarker/OFMarker (Christophe Vu-Brugier) - Add bidi support in target/user backend (ilias + vangelis + agover) - Move se_node_acl allocation into target-core code (hch) - Add crc_t10dif_update common helper (akinobu + mkp) - Handle target-core odd SGL mapping for data transfer memory (akinobu) - Move transport ID handling into target-core (hch) - Move task tag into struct se_cmd + support 64-bit tags (bart) - Convert se_node_acl->device_list[] to RCU hlist (nab + hch + paulmck) - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch + paulmck) - Simplify target backend driver registration (hch) - Consolidate + simplify target backend attribute implementations (hch + nab) - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch) - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab) - Drop unnecessary core_tpg_register TFO parameter (nab) - Use 64-bit LUNs tree-wide (hannes) - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (76 commits) target: Bump core version to v5.0 target: remove target_core_configfs.h target: remove unused TARGET_CORE_CONFIG_ROOT define target: consolidate version defines target: implement WRITE_SAME with UNMAP bit using ->execute_unmap target: simplify UNMAP handling target: replace se_cmd->execute_rw with a protocol_data field target/user: Fix inconsistent kmap_atomic/kunmap_atomic target: Send UA when changing LUN inventory target: Send UA upon LUN RESET tmr completion target: Send UA on ALUA target port group change target: Convert se_lun->lun_deve_lock to normal spinlock target: use 'se_dev_entry' when allocating UAs target: Remove 'ua_nacl' pointer from se_ua structure target_core_alua: Correct UA handling when switching states xen-scsiback: Fix compile warning for 64-bit LUN target: Remove TARGET_MAX_LUNS_PER_TRANSPORT target: use 64-bit LUNs target: Drop duplicate + unused se_dev_check_wce target: Drop unnecessary core_tpg_register TFO parameter ...

This patch also converts backend drivers to use call_rcu() release to allow any se_device readers to complete. The call_rcu() instead of kfree_rcu() is required here because se_device is embedded into the backend driver specific structure. Also, convert se_lun->lun_stats to use atomic_long_t within the target_complete_ok_work() completion callback, and add FIXME for transport_lookup_tmr_lun() with se_lun->lun_ref.

Have a single sbc_dif_verify that handles an sgl (that does NOT copy any data) and a protection information copy routine used by rd_mcp and fileio backend. In the WRITE case, call sbc_dif_verify with cmd->t_prot_sg and then do the copy from it to local sgl (assuming the verify succeeded of course). In the READ case, call sbc_dif_verify with the local sgl and if it succeeds, copy it to t_prot_sg (or not if we are stripping it).

target/rd: Don't pass incomplete scatterlist entries to sbc_dif_verify_* The scatterlist for protection information which is passed to sbc_dif_verify_read() or sbc_dif_verify_write() requires that neighboring scatterlist entries are contiguous or chained so that they can be iterated by sg_next(). However, the protection information for RD-MCP backends could be located in the multiple scatterlist arrays when the ramdisk space is too large. So if the read/write request straddles this boundary, sbc_dif_verify_read() or sbc_dif_verify_write() can't iterate all scatterlist entries. This problem can be fixed by chaining protection information scatterlist at creation time. For the architectures which don't support sg chaining (i.e. !CONFIG_ARCH_HAS_SG_CHAIN), fix it by allocating temporary scatterlist if needed.

target/rd: Convert to external rd_mcp_backend_dev_attrs This patch converts RAMDISK to use an external set of device attributes, and utilizes target_core_backend_configfs.h macros to generate a default set of configfs extended-attr handlers. It calls target_core_setup_sub_cits() to setup the initial config_item_type based on existing target_core_configfs.c defaults, and using configfs_attribute generated by DEF_TB_DEFAULT_ATTRIBS(rc_mcp) populates rd_mcp_backend_dev_attrs[] It introduces no functional change for existing RD_MCP device attributes.

target/rd: Add DIF protection into rd_execute_rw This patch adds support for DIF protection into rd_execute_rw() code for WRITE/READ I/O using sbc_dif_verify_[write,read]() logic.
target/rd: Add DIF protection into rd_execute_rw This patch adds support for DIF protection into rd_execute_rw() code for WRITE/READ I/O using sbc_dif_verify_[write,read]() logic. It also adds rd_get_prot_table() for locating protection SGLs assoicated with the ramdisk backend device. v2 changes: - Make rd_execute_rw() to u32 sectors count instead of sector_t - Drop SCF_PROT usage Cc: Martin K.

target/rd: Add support for protection SGL setup + release This patch adds rd_build_prot_space() + rd_release_prot_space() logic to setup + release protection information scatterlists.
target/rd: Add support for protection SGL setup + release This patch adds rd_build_prot_space() + rd_release_prot_space() logic to setup + release protection information scatterlists. It also adds rd_init_prot() + rd_free_prot() se_subsystem_api callbacks used by target core code for setup + release of protection information. v2 changes: - Drop unused sg_table from rd_release_prot_space (Wei) - Drop rd_release_prot_space call from rd_free_device Cc: Martin K.
