target: Update copyright ownership/year information to 2013

2013-09-11T03:23:36Z

Update copyright ownership/year information for target-core, loopback, iscsi-target, tcm_qla2xx, vhost and iser-target. Signed-off-by: Nicholas Bellinger

target: make queue_tm_rsp() return void

2013-07-08T01:36:53Z

The return value wasn't checked by any of the callers. Assuming this is correct behaviour, we can simplify some code by not bothering to generate it. nab: Add srpt_queue_data_in() + srpt_queue_tm_rsp() nops around srpt_queue_response() void return Signed-off-by: Joern Engel Signed-off-by: Nicholas Bellinger

tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls

2012-10-02T21:16:11Z

This patch converts tcm_loop to use target_submit_cmd_map_sgls() for I/O submission and mapping of pre-allocated SGL memory from incoming scsi_cmnd -> se_cmd descriptors. This includes removing the original open-coded fabric uses of target core callers to support transport_generic_map_mem_to_cmd() between target_setup_cmd_from_cdb() and transport_handle_cdb_direct() logic. (v2: Use renamed target_submit_cmd_map_sgls) Reported-by: Christoph Hellwig Reviewed-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: Simplify fabric sense data length handling

2012-09-18T00:12:58Z

Every fabric driver has to supply a se_tfo->set_fabric_sense_len() method, just so iSCSI can return an offset of 2. However, every fabric driver is already allocating a sense buffer and passing it into the target core, either via transport_init_se_cmd() or target_submit_cmd(). So instead of having iSCSI pass the start of its sense buffer into the core and then later tell the core to skip the first 2 bytes, it seems easier for iSCSI just to do the offset of 2 when it passes the sense buffer into the core. Then we can drop the se_tfo->set_fabric_sense_len() everywhere, and just add a couple of lines of code to iSCSI to set the sense data length to the beginning of the buffer right before it sends it over the network. (nab: Remove .set_fabric_sense_len usage from tcm_qla2xxx_npiv_ops + change transport_get_sense_buffer to follow v3.6-rc6 code w/o ->set_fabric_sense_len usage) Signed-off-by: Roland Dreier Signed-off-by: Nicholas Bellinger

target: Remove unused target_core_fabric_ops.get_fabric_sense_len method

2012-09-17T23:15:47Z

There are no callers of se_tfo->get_fabric_sense_len(), so we should stop having every fabric driver implement it. Signed-off-by: Roland Dreier Signed-off-by: Nicholas Bellinger

target: remove transport_generic_process_write

2012-07-17T00:35:16Z

Just call target_execute_cmd directly. Also, convert loopback, sbp, usb-gadget to use the newly exported target_execute_cmd(). Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: remove control CDB flags

2012-07-17T00:25:55Z

We don't need three flags to classifiy the CDB as we can check for a NULL S/G list for a dataless command, and can infer from the absence of the data flag that we deal with a control CDB. Also remove the _SG_IO from the data CDB flag as all I/O is dont on S/G lists now. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: Rename target_allocate_tasks to target_setup_cmd_from_cdb

2012-04-15T00:40:36Z

This patch renames a horribly misnamed function that no longer allocate tasks to something more descriptive for it's modern use in target core. (nab: Fix up ib_srpt to use this as well ahead of a target_submit_cmd conversion) Signed-off-by: Andy Grover Signed-off-by: Nicholas Bellinger

loopback: Fix transport_generic_allocate_tasks error handling

2012-03-18T01:07:27Z

This patch addresses a tcm_loop bug with transport_generic_allocate_tasks() return checking in tcm_loop_submission_work() where other non zero return codes (including -EBUSY for reservation conflicts) are incorrectly falling through to transport_generic_map_mem_to_cmd() -> transport_handle_cdb_direct(). This bug was introduced into target-pending/for-next-merge with the following for-3.4 commit: commit 16786454acec0e0e55e32d508b3058b32c1f23f3 Author: Christoph Hellwig Date: Thu Feb 2 17:04:42 2012 -0500 tcm_loop: switch to using transport_handle_cdb_direct Cc: Christoph Hellwig Signed-off-by: Nicholas Bellinger
