Pull SCSI target updates from Nicholas Bellinger: "Here are the outstanding target pending updates for v4.7-rc1. The highlights this round include: - Allow external PR/ALUA metadata path be defined at runtime via top level configfs attribute (Lee) - Fix target session shutdown bug for ib_srpt multi-channel (hch) - Make TFO close_session() and shutdown_session() optional (hch) - Drop se_sess->sess_kref + convert tcm_qla2xxx to internal kref (hch) - Add tcm_qla2xxx endpoint attribute for basic FC jammer (Laurence) - Refactor iscsi-target RX/TX PDU encode/decode into common code (Varun) - Extend iscsit_transport with xmit_pdu, release_cmd, get_rx_pdu, validate_parameters, and get_r2t_ttt for generic ISO offload (Varun) - Initial merge of cxgb iscsi-segment offload target driver (Varun) The bulk of the changes are Chelsio's new driver, along with a number of iscsi-target common code improvements made by Varun + Co along the way" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (29 commits) iscsi-target: Fix early sk_data_ready LOGIN_FLAGS_READY race cxgbit: Use type ISCSI_CXGBIT + cxgbit tpg_np attribute iscsi-target: Convert transport drivers to signal rdma_shutdown iscsi-target: Make iscsi_tpg_np driver show/store use generic code tcm_qla2xxx Add SCSI command jammer/discard capability iscsi-target: graceful disconnect on invalid mapping to iovec target: need_to_release is always false, remove redundant check and kfree target: remove sess_kref and ->shutdown_session iscsi-target: remove usage of ->shutdown_session tcm_qla2xxx: introduce a private sess_kref target: make close_session optional target: make ->shutdown_session optional target: remove acl_stop target: consolidate and fix session shutdown cxgbit: add files for cxgbit.ko iscsi-target: export symbols iscsi-target: call complete on conn_logout_comp iscsi-target: clear tx_thread_active iscsi-target: add new offload transport type iscsi-target: use conn_transport->transport_type in text rsp ...

cxgbit: Use type ISCSI_CXGBIT + cxgbit tpg_np attribute

2016-05-17T05:23:59Z

Instead of having cxgbit use type ISCSI_HW_OFFLOAD + 'hw_offload' tpg_np attribute, it should be using it's own driver specific type + attribute Cc: Varun Prakash Cc: Hariprasad Shenai Cc: Christoph Hellwig Cc: Sagi Grimberg Signed-off-by: Nicholas Bellinger

iscsi-target: Convert transport drivers to signal rdma_shutdown

2016-05-17T05:23:33Z

Instead of special casing the handful of callers that check for iser-target rdma verbs specific shutdown, use a simple flag at iscsit_transport->rdma_shutdown so each driver can signal this. Also, update iscsi-target/tcp + cxgbit to rdma_shutdown = false. Cc: Varun Prakash Cc: Hariprasad Shenai Cc: Christoph Hellwig Cc: Sagi Grimberg Signed-off-by: Nicholas Bellinger

target: enhance and export target_alloc_sgl/target_free_sgl

2016-05-13T17:37:19Z

The SRP target driver will need to allocate and chain it's own SGLs soon. For this export target_alloc_sgl, and add a new argument to it so that it can allocate an additional chain entry that doesn't point to a page. Also export transport_free_sgl after renaming it to target_free_sgl to free these SGLs again. Signed-off-by: Christoph Hellwig Reviewed-by: Bart Van Assche Signed-off-by: Doug Ledford

target: remove sess_kref and ->shutdown_session

2016-05-10T08:19:49Z

Both of them are unused now that drivers handle any delayed session shutdown internally. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: remove acl_stop

2016-05-10T08:19:11Z

Ensure we can use list_empty on the sess_acl_list to remove the need for this flag. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

iscsi-target: export symbols

2016-05-10T06:12:28Z

export symbols for ISCSI_HW_OFFLOAD transport drivers. Signed-off-by: Varun Prakash Signed-off-by: Nicholas Bellinger

iscsi-target: add new offload transport type

2016-05-10T06:12:18Z

Add new transport type ISCSI_HW_OFFLOAD, hw offload transport drivers will use this transport type. Signed-off-by: Varun Prakash Signed-off-by: Nicholas Bellinger

iscsi-target: move iscsit_thread_check_cpumask()

2016-05-10T06:12:09Z

Move iscsit_thread_check_cpumask() to header file so that ISCSI_HW_OFFLOAD and other transport drivers can call this function to ensure both tx and rx thread runs on same cpu. Signed-off-by: Varun Prakash Signed-off-by: Nicholas Bellinger

iscsi-target: add void (*iscsit_get_r2t_ttt)()

2016-05-10T06:12:08Z

Add void (*iscsit_get_r2t_ttt)() to struct iscsit_transport, iscsi-target uses this callback to get r2t->targ_xfer_tag. cxgbit.ko needs this callback for Direct Data Placement of Data Out pdus, adapter uses ttt in Data Out pdus for placing data directly in to the host buffers.
