      target: fix COMPARE_AND_WRITE non zero SGL offset data corruption · d94e5a61
      Jan Engelhardt authored
      
      
      target_core_sbc's compare_and_write functionality suffers from taking
      data at the wrong memory location when writing a CAW request to disk
      when a SGL offset is non-zero.
      
      This can happen with loopback and vhost-scsi fabric drivers when
      SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC is used to map existing user-space
      SGL memory into COMPARE_AND_WRITE READ/WRITE payload buffers.
      
      Given the following sample LIO subtopology,
      
      % targetcli ls /loopback/
      o- loopback ................................. [1 Target]
        o- naa.6001405ebb8df14a ....... [naa.60014059143ed2b3]
          o- luns ................................... [2 LUNs]
            o- lun0 ................ [iblock/ram0 (/dev/ram0)]
            o- lun1 ................ [iblock/ram1 (/dev/ram1)]
      % lsscsi -g
      [3:0:1:0]    disk    LIO-ORG  IBLOCK           4.0   /dev/sdc   /dev/sg3
      [3:0:1:1]    disk    LIO-ORG  IBLOCK           4.0   /dev/sdd   /dev/sg4
      
      the following bug can be observed in Linux 4.3 and 4.4~rc1:
      
      % perl -e 'print chr$_ for 0..255,reverse 0..255' >rand
      % perl -e 'print "\0" x 512' >zero
      % cat rand >/dev/sdd
      % sg_compare_and_write -i rand -D zero --lba 0 /dev/sdd
      % sg_compare_and_write -i zero -D rand --lba 0 /dev/sdd
      Miscompare reported

      Rather than writing all-zeroes as instructed with the -D file, it
      corrupts the data in the sector by splicing some of the original
      bytes in. The page of the first entry of cmd->t_data_sg includes the
      CDB, and sg->offset is set to a position past the CDB. I presume that
      sg->offset is also the right choice to use for subsequent sglist
      members.

      target: Fix race for SCF_COMPARE_AND_WRITE_POST checking · 057085e5
      Nicholas Bellinger authored
      
      
      This patch addresses a race + use after free where the first
      stage of COMPARE_AND_WRITE in compare_and_write_callback()
      is rescheduled after the backend sends the secondary WRITE,
      resulting in second stage compare_and_write_post() callback
      completing in target_complete_ok_work() before the first
      can return.
      
      Because current code depends on checking se_cmd->se_cmd_flags
      after return from se_cmd->transport_complete_callback(),
      this results in first stage having SCF_COMPARE_AND_WRITE_POST
      set, which incorrectly falls through into second stage CAW
      processing code, eventually triggering a NULL pointer
      dereference due to use after free.
      
      To address this bug, pass in a new *post_ret parameter into
      se_cmd->transport_complete_callback(), and depend upon this
      value instead of ->se_cmd_flags to determine when to return
      or fall through into ->queue_status() code for CAW.

      iscsi-target: Fix rx_login_comp hang after login failure · ca82c2bd
      Nicholas Bellinger authored
      This patch addresses a case where iscsi_target_do_tx_login_io()
      fails sending the last login response PDU, after the RX/TX
      threads have already been started.
      
      The case centers around iscsi_target_rx_thread() not invoking
      allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs
      from the failure path, resulting in RX thread hanging
      indefinately on iscsi_conn->rx_login_comp.
      
      Note this bug is a regression introduced by:

      ARM: 8454/1: OF implies OF_FLATTREE · aa7d5f18
      Arnd Bergmann authored
      
      
      On the ARM architecture, individual platforms select CONFIG_USE_OF if they
      need it, but all device tree code is keyed off CONFIG_OF. When building
      a platform without DT support and manually enabling CONFIG_OF, we now
      get a number of build errors, e.g.
      
      arch/arm/kernel/devtree.c: In function 'setup_machine_fdt':
      arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration]
      
      We could now try to separate the use case of booting from DT vs. the
      case of using the dynamic implementation, but that seems more complicated
      than it can gain us.
      
      This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM
      and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little
      extra code when we just want the dynamic OF implementation, but that seems
      like a rather obscure case, and this version solves all CONFIG_OF related
      randconfig regressions.

       "There is a small backlog of at91 patches here, the most significant is
        the addition of some sama5d2 Xplained nodes that were waiting on an
        MFD include file to get merged through another tree.
      
        We normally try to sort those out before the merge window opens, but
        the maintainer wasn't aware of that here and I decided to merge the
        changes this time as an exception.
      
        On OMAP a series of audio changes for dra7 missed the merge window but
        turned out to be necessary to fix a boot time imprecise external abort
        error and to get audio working.
      
        The other changes are the usual simple changes, here is a list sorted
        by platform:
      
        at91:
      	removal of a useless defconfig option
      	removal of some legacy DT pieces

        mvebu:
      	fix QNAP TS219 power-off in dts
      	fix legacy get_irqnr_and_base for dove and orion5x

      	fix l4 related boot time errors for dm81xx
      	use lockless cldm/pwrdm api in omap4_boot_secondary
      	remove t410 abort handler to avoid hiding other critical errors
      	mark cpuidle tracepoints as _rcuidle
      	fix module alias for omap-ocp2scp
      
        pxa:
      	palm: Fix typos in PWM lookup table code
      
        renesas:
      	missing __initconst annotation for r8a7793_boards_compat_dt

           over to the "performance" mode via sysfs if hardware-driven P-state
           selection (HWP) is enabled (Alexandra Yates).

      GCC 4.1 and newer remove empty loops.  This becomes a problem when delay
      loops get removed.  Fixed by rewriting to user the proper Linux interface
