scsi: target: Use standard SAM status types

2021-06-01T02:48:24Z

target_complete_cmd() and friends requires a SAM status type, so passing GOOD here is actually wrong. Link: https://lore.kernel.org/r/20210427083046.31620-40-hare@suse.de Reviewed-by: Bart Van Assche Signed-off-by: Hannes Reinecke Signed-off-by: Martin K. Petersen

scsi: target: core: Add the VERSION DESCRIPTOR fields to the INQUIRY data

2021-05-15T18:34:26Z

Extend the standard INQUIRY data to 96 bytes and fill in the VERSION DESCRIPTOR fields. The layout follows SPC-4: - SCSI architecture standard - SCSI transport protocol standard - SCSI primary command set standard - SCSI device type command set standard All version descriptor values are defined as "no version claimed" because some initiators fail to recognize anything else.

scsi: target: core: Bump INQUIRY VERSION to SPC-4

2021-05-15T18:34:26Z

Bump the SCSI primary command set standard to SPC-4. The upcoming version descriptors will report newer SCSI standards (like SBC-3) that are not defined in SPC-3.

scsi: target: core: Add configurable IEEE Company ID attribute

2021-05-15T18:14:28Z

Implement an attribute which provides a way to set a company specific WWN in configfs via: target/core/$backstore/$name/wwn/company_id The Open Fabrics Alliance ID 001405h remains the default.

scsi: target: core: Unify NAA identifier generation

2021-05-15T18:14:28Z

Both the INQUIRY handling and the XCOPY implementation provide functions to generate an NAA designator. In addition, these functions are poorly named: - spc_parse_naa_6h_vendor_specific() - target_xcopy_gen_naa_ieee() Introduce a common NAA 6 designator generation function, spc_gen_naa_6h_vendor_specific().

scsi: target: Make the virtual LUN 0 device

2021-04-06T03:26:39Z

Create the device for the virtual LUN 0 using the DUMMY flag. This change makes it possible to remove some special-casing in the INQUIRY code.

scsi: target: use an enum to track emulate_ua_intlck_ctrl

2020-02-21T22:37:16Z

The emulate_ua_intlck_ctrl device attribute accepts values of 0, 1 or 2 via ConfigFS, which map to unit attention interlocks control codes in the MODE SENSE control Mode Page. Use an enum to track these values so that it's clear that, unlike the remaining emulate_X attributes, emulate_ua_intlck_ctrl isn't boolean.

scsi: target: consistently null-terminate t10_wwn strings

2018-12-08T02:54:33Z

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.
