      target/configfs: Expose protection device attributes · 2ed22c9c
      Nicholas Bellinger authored
      This patch adds support for exposing DIF protection device
      attributes via configfs.  This includes:
      
         pi_prot_type: Protection Type (0, 1, 3 currently support)
         pi_prot_format: Protection Format Operation (FILEIO only)
      
      Within se_dev_set_pi_prot_type() it also adds the se_subsystem_api
      device callbacks to setup per device protection information.
      
      v2 changes:
        - Drop pi_guard_type + pi_prot_version related code (MKP)
        - Add pi_prot_format logic (Sagi)
        - Add ->free_prot callback in target_free_device
        - Add hw_pi_prot_type read-only attribute

      target/sbc: Add DIF TYPE1+TYPE3 read/write verify emulation · 41861fa8
      Nicholas Bellinger authored
      This patch adds support for DIF read/write verify emulation
      for TARGET_DIF_TYPE1_PROT + TARGET_DIF_TYPE3_PROT operation.
      
      This includes sbc_dif_verify_write() + sbc_dif_verify_read()
      calls accessable by backend drivers to perform DIF verify
      for SGL based data and protection information.
      
      Also included is sbc_dif_copy_prot() logic to copy protection
      information to/from backend provided protection SGLs.
      
      Based on scsi_debug.c DIF TYPE1+TYPE3 emulation.
      
      v2 changes:
        - Select CRC_T10DIF for TARGET_CORE in Kconfig (Fengguang)
        - Drop IP checksum logic from sbc_dif_v1_verify (MKP)
        - Fix offset on app_tag = 0xffff in sbc_dif_verify_read()

      target/sbc: Add DIF setup in sbc_check_prot + sbc_parse_cdb · 499bf77b
      Nicholas Bellinger authored
      This patch adds sbc_check_prot() for performing various DIF
      related CDB sanity checks, along with setting cmd->prot_type
      once sanity checks have passed.
      
      Also, add calls in sbc_parse_cdb() for READ_[10,12,16] +
      WRITE_[10,12,16] to perform DIF sanity checking.
      
      v2 changes:
        - Make sbc_check_prot defined as static (Fengguang + Wei)
        - Remove unprotected READ/WRITE warning (mkp)
        - Populate cmd->prot_type + friends (Sagi)
        - Drop SCF_PROT usage

      Nicholas Bellinger authored
      This patch adds DIF related definitions to target_core_base.h
      that includes enums for target_prot_op + target_prot_type +
      target_prot_version + target_guard_type + target_pi_error.
      
      Also included is struct se_dif_v1_tuple, along with changes
      to struct se_cmd, struct se_dev_attrib, and struct se_device.
      
      Also, add new se_subsystem_api->[init,format,free]_prot() callers
      used by target core code to setup backend specific protection
      information after the device has been configured.
      
      Enums taken from Sagi Grimberg's original patch.
      
      v2 changes:
        - Drop guard_type related definitions

      Pull tracing fix from Steven Rostedt:
       "A regression showed up that there's a large delay when enabling all
        events.  This was prevalent when FTRACE_SELFTEST was enabled which
        enables all events several times, and caused the system bootup to
        pause for over a minute.
      
        This was tracked down to an addition of a synchronize_sched()
        performed when system call tracepoints are unregistered.
      
        The synchronize_sched() is needed between the unregistering of the
        system call tracepoint and a deletion of a tracing instance buffer.
        But placing the synchronize_sched() in the unreg of *every* system
        call tracepoint is a bit overboard.  A single synchronize_sched()
        before the deletion of the instance is sufficient"
