scsi: add bsg support The Linux kernel supports two different versions of the SG_IO API, namely v3 and v4. This patch adds support for version 4 of this API. At least the sg3_utils package supports version 4 of this API. Version 4 of this API is used if /dev/bsg/H:C:I:L is used as device name. This patch has been tested by inspecting the output of the following commands: modprobe scsi_debug dev_size_mb=16 delay=0 dev=$(lsscsi \| sed -n '/ scsi_debug /s,^[^/],,p') ./strace -eioctl -s256 sg_inq $dev echo 'Test XDWRITEREAD(10)' bsg=/dev/bsg/$(lsscsi \| sed -n '/ scsi_debug /s,^\[\([^]]\+\)\].,\1,p') dd if=/dev/zero bs=512 count=1 \| ./strace -eioctl -s256 sg_raw -s 512 -r 1024 $bsg 53 00 00 00 00 01 00 00 01 00 * configure.ac (AC_CHECK_HEADERS): Add linux/bsg.h. * xlat/bsg_protocol.in: New file. * xlat/bsg_subprotocol.in: Likewise. * scsi.c: Include them and <linux/bsg.h>. (print_sg_io_v3_req, print_sg_io_v3_res, print_sg_io_v4_req, print_sg_io_v4_res): New functions. (print_sg_io_req, print_sg_io_res): Use them. (scsi_ioctl): Update callers.
