This small patchset addresses some issues with descriptor format
sense data.
Patch 1 fixes wrong additional sense length for descriptor format
information field.
Patch 2 protects against buffer overflow in scsi_set_information_sense
(reported by Hannes).
Patch 3 converts the target stack to report descriptor format sense
data to for LUs that spans 64bit sectors in order to avoid info
truncation (reported by hch).
Patch 4 is a nit, it was included in this to avoid dependencies
(patch 2/4)
Changes from v0:
- Added patch 4/4 to avoid dependencies
- Modified patch 3/4 to use descriptor format only for LUs that
span 64bit sectors.
- Added reviwed-by tags.
Sagi Grimberg (4):
scsi: Fix wrong additional sense length in descriptor format
scsi: Protect against buffer possible overflow in
scsi_set_sense_information
target: Return descriptor format sense data in case the LU spans 64bit
sectors
libiscsi: Use scsi helper to set information descriptor
