[PATCH v3 0/3] Fixes for scsi_mode_sense/select()

From: Damien Le Moal <hidden>
Date: 2021-08-20 07:04:58

The first patch in this series is the formet standalone patch titled
"scsi: fix scsi_mode_sense()". Patch 2 fixes similar buffer length
handling problems found in scsi_mode_select().
Patch 3 fixes the use of scsi_mode_sense() in sd.c to ensure that calls
are issued with a sensible buffer size for devices that explicitly
requested the use of MODE SENSE 10 (e.g. SATA drives on AHCI).

Changes from v2:
* Added patch 3

Changes from v1:
* Patch 1:
  - Added check on the buffer length not being larger than 65535 bytes
    for the MODE SENSE 10 case.
  - Automatically try MODE SENSE 10 for large requests even if the
    device does not have use_10_for_ms set
* Added patch 2

Damien Le Moal (3):
  scsi: fix scsi_mode_sense() buffer length handling
  scsi: fix scsi_mode_select() buffer length handling
  scsi: sd: fix sd_do_mode_sense() buffer length handling
