Ondrej Kozina 9e05a2599a sed-opal: geometry feature reporting command ... Locking range start and locking range length attributes may be require to satisfy restrictions exposed by OPAL2 geometry feature reporting. Geometry reporting feature is described in TCG OPAL SSC, section 3.1.1.4 (ALIGN, LogicalBlockSize, AlignmentGranularity and LowestAlignedLBA). 4.3.5.2.1.1 RangeStart Behavior: [ StartAlignment = (RangeStart modulo AlignmentGranularity) - LowestAlignedLBA ] When processing a Set method or CreateRow method on the Locking table for a non-Global Range row, if: a) the AlignmentRequired (ALIGN above) column in the LockingInfo table is TRUE; b) RangeStart is non-zero; and c) StartAlignment is non-zero, then the method SHALL fail and return an error status code INVALID_PARAMETER. 4.3.5.2.1.2 RangeLength Behavior: If RangeStart is zero, then [ LengthAlignment = (RangeLength modulo AlignmentGranularity) - LowestAlignedLBA ] If RangeStart is non-zero, then [ LengthAlignment = (RangeLength modulo AlignmentGranularity) ] When processing a Set method or CreateRow method on the Locking table for a non-Global Range row, if: a) the AlignmentRequired (ALIGN above) column in the LockingInfo table is TRUE; b) RangeLength is non-zero; and c) LengthAlignment is non-zero, then the method SHALL fail and return an error status code INVALID_PARAMETER In userspace we stuck to logical block size reported by general block device (via sysfs or ioctl), but we can not read 'AlignmentGranularity' or 'LowestAlignedLBA' anywhere else and we need to get those values from sed-opal interface otherwise we will not be able to report or avoid locking range setup INVALID_PARAMETER errors above.
