scsi: target: consistently null-terminate t10_wwn strings In preparation for supporting user provided vendor strings, add an extra byte to the vendor, model and revision arrays in struct t10_wwn. This ensures that the full INQUIRY data can be carried in the arrays along with a null-terminator. Change a number of array readers and writers so that they account for explicit null-termination: - The pscsi_set_inquiry_info() and emulate_model_alias_store() codepaths don't currently explicitly null-terminate; fix this. - Existing t10_wwn field dumps use for-loops which step over null-terminators for right-padding. + Use printf with width specifiers instead.

scsi: target: add emulate_pr backstore attr to toggle PR support The new emulate_pr backstore attribute allows for Persistent Reservation and SCSI2 RESERVE/RELEASE support to be completely disabled. This can be useful for scenarios such as: - Ensuring ATS (Compare & Write) usage on recent VMware ESXi initiators. - Allowing clustered (e.g. tcm-user) backends to block such requests, avoiding the multi-node reservation state propagation. When explicitly disabled, PR and RESERVE/RELEASE requests receive Invalid Command Operation Code response sense data.

target/qla2xxx: Honor max_data_sg_nents I/O transfer limit This patch adds an optional fabric driver provided SGL limit that target-core will honor as it's own internal I/O maximum transfer length limit, as exposed by EVPD=0xb0 block limits parameters. This is required for handling cases when host I/O transfer length exceeds the requested EVPD block limits maximum transfer length. The initial user of this logic is qla2xxx, so that we can avoid having to reject I/Os from some legacy FC hosts where EVPD=0xb0 parameters are not honored. When se_cmd payload length exceeds the provided limit in target_check_max_data_sg_nents() code, se_cmd->data_length + se_cmd->prot_length are reset with se_cmd->residual_count plus underflow bit for outgoing TFO response callbacks. It also checks for existing CDB level underflow + overflow and recalculates final residual_count as necessary. Note this patch currently assumes 1:1 mapping of PAGE_SIZE per struct scatterlist entry.

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 ...

target: Minimize SCSI header #include directives Only include SCSI initiator header files in target code that needs these header files, namely the SCSI pass-through code and the tcm_loop driver. Change SCSI_SENSE_BUFFERSIZE into TRANSPORT_SENSE_BUFFER in target code because the former is intended for initiator code and the latter for target code. With this patch the only initiator include directives in target code that remain are as follows: $ git grep -nHE 'include .scsi/(scsi.h|scsi_host.h|scsi_device.h|scsi_cmnd.h)' drivers/target drivers/infiniband/ulp/{isert,srpt} drivers/usb/gadget/legacy/tcm_*.[ch] drivers/{vhost,xen} include/{target,trace/events/target.h} drivers/target/loopback/tcm_loop.c:29:#include <scsi/scsi.h> drivers/target/loopback/tcm_loop.c:31:#include <scsi/scsi_host.h> drivers/target/loopback/tcm_loop.c:32:#include <scsi/scsi_device.h> drivers/target/loopback/tcm_loop.c:33:#include <scsi/scsi_cmnd.h> drivers/target/target_core_pscsi.c:39:#include <scsi/scsi_device.h> drivers/target/target_core_pscsi.c:40:#include <scsi/scsi_host.h> drivers/xen/xen-scsiback.c:52:#include <scsi/scsi_host.h> /* SG_ALL */ Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <JBottomley@Odin.com>

target: Drop lun_sep_lock for se_lun->lun_se_dev RCU usage With se_port and t10_alua_tg_pt_gp_member being absored into se_lun, there is no need for an extra lock to protect se_lun->lun_se_dev assignment. 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. Finally, update sbp_update_unit_directory() special case usage with proper rcu_dereference_raw() and configfs symlink comment.

target: Subsume se_port + t10_alua_tg_pt_gp_member into se_lun This patch eliminates all se_port + t10_alua_tg_pt_gp_member usage, and converts current users to direct se_lun pointer dereference. This includes the removal of core_export_port(), core_release_port() core_dev_export() and core_dev_unexport(). Along with conversion of special case se_lun pointer dereference within PR ALL_TG_PT=1 and ALUA access state transition UNIT_ATTENTION handling. Also, update core_enable_device_list_for_node() to reference the new per se_lun->lun_deve_list when creating a new entry, or replacing an existing one via RCU.

target: Convert se_node_acl->device_list[] to RCU hlist This patch converts se_node_acl->device_list[] table for mappedluns to modern RCU hlist_head usage in order to support an arbitrary number of node_acl lun mappings. It converts transport_lookup_*_lun() fast-path code to use RCU read path primitives when looking up se_dev_entry. It adds a new hlist_head at se_node_acl->lun_entry_hlist for this purpose. For transport_lookup_cmd_lun() code, it works with existing per-cpu se_lun->lun_ref when associating se_cmd with se_lun + se_device. Also, go ahead and update core_create_device_list_for_node() + core_free_device_list_for_node() to use ->lun_entry_hlist. It also converts se_dev_entry->pr_ref_count access to use modern struct kref counting, and updates core_disable_device_list_for_node() to kref_put() and block on se_deve->pr_comp waiting for outstanding PR special-case PR references to drop, then invoke kfree_rcu() to wait for the RCU grace period to complete before releasing memory. So now that se_node_acl->lun_entry_hlist fast path access uses RCU protected pointers, go ahead and convert remaining non-fast path RCU updater code using ->lun_entry_lock to struct mutex to allow callers to block while walking se_node_acl->lun_entry_hlist. Finally drop the left-over core_clear_initiator_node_from_tpg() that originally cleared lun_access during se_node_acl shutdown, as post RCU conversion it now becomes duplicated logic.
