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. David Disseldorp (5): target: use consistent left-aligned ASCII INQUIRY data target: consistently null-terminate t10_wwn strings target: add device vendor_id configfs attribute target: remove hardcoded T10 Vendor ID in INQUIRY response target: perform t10_wwn ID initialisation in target_alloc_device() drivers/target/target_core_configfs.c | 86 +++++++++++++++++++++++++-- drivers/target/target_core_device.c | 55 +++++------------ drivers/target/target_core_pscsi.c | 50 +++++----------- drivers/target/target_core_spc.c | 20 +++++-- drivers/target/target_core_stat.c | 32 +++------- include/target/target_core_base.h | 14 ++++- 6 files changed, 145 insertions(+), 112 deletions(-)
