This patch adds a new target_core_fabric_ops callback for allowing fabric
drivers to expose a TPG attribute for signaling when a T10-PI protected
fabric wants to function with an un-protected device without T10-PI.
This specifically is to allow LIO
From: Nicholas Bellinger n...@linux-iscsi.org
This patch changes existing DIF emulation to check the command descriptor's
prot_type, instead of what the backend device is exposing in pi_prot_type.
Since this value is already set in sbc_check_prot(), go ahead and use it to
allow protected fabrics

Hi MKP, Sagi, Quinn, Co,
Here is -v2 for adding target internal WRITE_STRIP + READ_INSERT
DIX emulation using target_core_sbc.c + crct10dif.ko code.
This mode is for allowing T10-PI capable fabrics to interoperate with
backend devices that have not

Make sure that FILEIO only attempts to use backend DIF emulation
when it's actually enabled at device level.

This patch updates standard INQUIRY, INQUIRY EVPD=0x86, READ_CAPACITY_16
and control mode pages to use se_sess-sess_prot_type when determing which
type of T10-PI related feature bits can be exposed.
This is required for fabric sessions supporting

This patch adds the missing TARGET_PROT_ALL when initializing a new
session and declaring the capable se_sess-sup_prot_ops for T10-PI.
This is required in order to function with existing qla_target.c
DIF protection offload support.

This patch adds WRITE_STRIP support in target_check_write_prot() that

submitting the I/O to a backend driver.
Upon verify failure, the specific sense code is propigated up the
