Also included are some minor fixes and improvements. This series is based on the original work done by Jonas Rabenstein which was submitted in March 2018.[1] There is a fork of sed-opal-temp that can use these new IOCTLs.[2] I tested these on Samsung 840 EVO and 850 EVO drives, on x86-64 and arm64 systems. The series applies on v5.0-rc4. I'm resending as v4 as suggested by Scott Bauer.[3] Changes from v3 to v4: * added Reviewed-by from Scott, including for the patch 16/16 (details in [3]) [1] https://lore.kernel.org/lkml/cover.1521482295.git.jonas.rabenstein@studium.uni-erlangen.de/ [2] https://github.com/ghostav/sed-opal-temp [3] https://lore.kernel.org/lkml/20190127211449.GP21149@hacktheplanet/ David Kozub (8): block: sed-opal: fix typos and formatting block: sed-opal: close parameter list in cmd_finalize block: sed-opal: unify cmd start block: sed-opal: unify error handling of responses block: sed-opal: reuse response_get_token to decrease code duplication block: sed-opal: pass steps via argument rather than via opal_dev block: sed-opal: don't repeat opal_discovery0 in each steps array block: sed-opal: rename next to execute_steps Jonas Rabenstein (8): block: sed-opal: use correct macro for method length block: sed-opal: unify space check in add_token_* block: sed-opal: print failed function address block: sed-opal: split generation of bytestring header and content block: sed-opal: add ioctl for done-mark of shadow mbr block: sed-opal: ioctl for writing to shadow mbr block: sed-opal: unify retrieval of table columns block: sed-opal: check size of shadow mbr block/opal_proto.h | 18 + block/sed-opal.c | 845 +++++++++++++++++----------------- include/linux/sed-opal.h | 2 + include/uapi/linux/sed-opal.h | 9 + 4 files changed, 451 insertions(+), 423 deletions(-) -- 2.20.1
