target: Make spc_get_write_same_sectors return sector_t

2012-11-28T06:49:25+00:00

We already expect TFO->get_blocks() to return sector_t for zero value case when doing WRITE_SAME to the end of the backend device, so go ahead and return sector_t from spc_get_write_same_sectors() to handle this case properly. Also, update the single iblock_execute_write_same() caller of this code. Cc: Christoph Hellwig Cc: Martin K. Petersen Signed-off-by: Nicholas Bellinger

target/sbc: Seperate WRITE_SAME based on UNMAP flag in sbc_ops

2012-11-15T20:04:52+00:00

This patch adds a new sbc_ops->execute_write_same_unmap() caller for use with WRITE_SAME w/ UNMAP=1, and performs the ->execute_cmd() setup based this bit within sbc_setup_write_same() code. Also, makes the changes in sbc_parse_cdb() to handle a sense_reason_t return from sbc_setup_write_same() on error. Reported-by: Christoph Hellwig Cc: Martin K.

target: pass sense_reason as a return value

2012-11-07T04:55:46+00:00

Pass the sense reason as an explicit return value from the I/O submission path instead of storing it in struct se_cmd and using negative return values. This cleans up a lot of the code pathes, and with the sparse annotations for the new sense_reason_t type allows for much better error checking.

target: remove ->get_device_rev

2012-11-07T04:55:45+00:00

Now that the reservations and ALUA code have been cleaned up there is no need for the get_device_rev method, as we only need the standards revision in the inquiry data, where we can hardcode it. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: provide generic sbc device type/revision helpers

target/pscsi: call spc_emulate_report_luns directly

2012-11-07T04:55:44+00:00

No need to indirect through spc_parse_cdb if we only ever call it for REPORT LUNS emulation. (nab: Add missing EXPORT_SYMBOL for spc_emulate_report_luns) Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: rename spc_ops

2012-11-07T04:55:44+00:00

These really are sbc_ops, so name them correctly. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: kill struct se_subsystem_dev

2012-11-07T04:55:43+00:00

Simplify the code a lot by killing the superflous struct se_subsystem_dev. Instead se_device is allocated early on by the backend driver, which allocates it as part of its own per-device structure, borrowing the scheme that is for example used for inode allocation.

target: Drop se_subsystem_api->[write_cache,fua_write]_emulated flags

2012-09-18T00:13:34+00:00

This patch drops se_subsystem_api->[write_cache,fua_write]_emulated flags set by viritual FILEIO/IBLOCK/RD_MCP backend drivers in favor of explict TRANSPORT_PLUGIN_PHBA_PDEV checks to know when to fail if userspace is attempting to set virtual emulation bits for an pSCSI (passthrough) backend device.

target: fix use-after-free with PSCSI sense data

2012-09-06T00:20:28+00:00

The pointer to the sense buffer is fetched by transport_get_sense_data, but this is called by target_complete_ok_work long after pscsi_req_done has freed the struct that contains it. Pass instead the fabric's sense buffer to transport_complete, and copy the data to it directly in transport_complete. Setting SCF_TRANSPORT_TASK_SENSE also becomes a duty of transport_complete.
