Several SCSI command implementations in UefiScsiLib encode the LUN in Cdb[1] bits [7:5]. For READ and WRITE commands, this conflicts directly with the RDPROTECT and WRPROTECT bitfield definitions in SBC-3, whereas for a number of other commands it conflicts with Reserved (all-bits-zero) bitfield definitions in SPC-4 and SBC-3.
New in v4: - format patches with 11 context lines for easier reviewability - add patch #2 to update SCSI commands different from READ and WRITE too [Feng] - public branch: https://github.com/lersek/edk2/commits/bz1166971_rdwrvr_cdb_lun_encode_v4 Thanks, Laszlo Laszlo Ersek (2): MdePkg: UefiScsiLib: do not encode LUN in CDB for READ and WRITE MdePkg: UefiScsiLib: do not encode LUN in CDB for other SCSI commands MdePkg/Library/UefiScsiLib/UefiScsiLib.c | 81 +------------------------------- 1 file changed, 1 insertion(+), 80 deletions(-) -- 1.8.3.1 ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
