[PATCH v7 0/5] target: user configurable T10 Vendor ID

[David Disseldorp <ddiss@suse.de>]

This patch-set allows for the modification of the T10 Vendor
Identification string returned in the SCSI INQUIRY response, via the
target/core/$backstore/$name/wwn/vendor_id ConfigFS path.

Changes since v6:
- PATCH 2/5
  + fill pscsi inquiry data using proper sd->inquiry pointer names
  + dump pscsi sd->inquiry data using sprintf
  + tweak emulate_model_alias truncation warning
  + drop a few duplicate BUILD_BUG_ON()s
  + drop Hannes' sign-off
- PATCH 3/5
  + check user vendor string for non-ascii-printable chars
  + strip newline before INQUIRY_VENDOR_LEN length check
  + drop sign-offs from Bryant, Lee and Hannes

Changes since v5:
- remove unnecessary TRANSPORT_FLAG_PASSTHROUGH conditional from t10_wwn
  ID defaults initialisation.

Changes since v4:
- merge null-termination changes into a single patch
- add patch to initialise t10_wwn ID defaults earlier
- use strlcpy() instead of strncpy() in some places

Changes since v3:
- perform explicit null termination of t10_wwn vendor, model and
  revision fields.
- replace field dump for-loops

Changes since v2:
- https://www.spinics.net/lists/target-devel/msg10720.html
- Support eight byte vendor ID strings
- Split out consistent INQUIRY data padding as a separate patch
- Drop t10_wwn.model buffer print fix, already upstream

Changes since v1:
- https://www.spinics.net/lists/target-devel/msg10545.html
- Rebase against nab's for-next branch, which includes Christoph's
  configfs API changes.
