      ipmi: kcs_bmc: handle devm_kasprintf() failure case · 42c7c6ef
      Nicholas Mc Guire authored
      devm_kasprintf() may return NULL if internal allocation failed so this
      assignment is not safe. Moved the error exit path and added the !NULL
      which then allows the devres manager to take care of cleanup.

      ipmi: Fix return value when a message is truncated · 95ac0daa
      Corey Minyard authored
      The user can ask the message to be returned even if it didn't supply
      enough memory for the data, and it will return an error but still
      fills in as much data as possible.   However, the return value
      wasn't being set to an error, it was being overwritten.  Create a
      second return value for that case.

      ipmi: Make the smi watcher be disabled immediately when not needed · e1891cff
      Corey Minyard authored
      The code to tell the lower layer to enable or disable watching for
      certain things was lazy in disabling, it waited until a timer tick
      to see if a disable was necessary.  Not a really big deal, but it
      could be improved.
      
      Modify the code to enable and disable watching immediately and don't
      do it from the background timer any more.

      ipmi: Fix how the lower layers are told to watch for messages · c65ea996
      Corey Minyard authored
      The IPMI driver has a mechanism to tell the lower layers it needs
      to watch for messages, commands, and watchdogs (so it doesn't
      needlessly poll).  However, it needed some extensions, it needed
      a way to tell what is being waited for so it could set the timeout
      appropriately.
      
      The update to the lower layer was also being done once a second
      at best because it was done in the main timeout handler.  However,
      if a command is sent and a response message is coming back,
      it needed to be started immediately.  So modify the code to
      update immediately if it needs to be enabled.  Disable is still
      lazy.

      ipmi: Fix SSIF flag requests · a1466ec5
      Corey Minyard authored
      Commit 89986496 ("ipmi: Turn off all activity on an idle ipmi
      interface") modified the IPMI code to only request events when the
      driver had somethine waiting for events.  The SSIF code, however,
      was using the event fetch request to also fetch the flags.
      
      Add a timer and the proper handling for the upper layer telling
      whether flags fetches are required.

      If io_setup is called successful in try_smi_init() but try_smi_init()
      goes out_err before calling ipmi_register_smi(), so ipmi_unregister_smi()
      will not be called while removing module. It leads to the resource that
      allocated in io_setup() can not be freed, but the name(DEVICE_NAME) of
      resource is freed while removing the module. It causes use-after-free
      when cat /proc/ioports.
      
      Fix this by calling io_cleanup() while try_smi_init() goes to out_err.
      and don't call io_cleanup() until io_setup() returns successful to avoid
      warning prints.

      Pull MIPS fixes from Paul Burton:
       "A batch of MIPS fixes for 5.0, nothing too scary.
      
         - A workaround for a Loongson 3 CPU bug is the biggest change, but
           still fairly straightforward. It adds extra memory barriers (sync
           instructions) around atomics to avoid a CPU bug that can break
           atomicity.
      
         - Loongson64 also sees a fix for powering off some systems which
           would incorrectly reboot rather than waiting for the power down
           sequence to complete.
      
         - We have DT fixes for the Ingenic JZ4740 SoC & the JZ4780-based Ci20
           board, and a DT warning fix for the Nexsys4/MIPSfpga board.
      
         - The Cavium Octeon platform sees a further fix to the behaviour of
           the pcie_disable command line argument that was introduced in v3.3.
      
         - The VDSO, introduced in v4.4, sees build fixes for configurations
           of GCC that were built using the --with-fp-32= flag to specify a
           default 32-bit floating point ABI.
      
         - get_frame_info() sees a fix for configurations with
           CONFIG_KALLSYMS=n, for which it previously always returned an
           error.
      
         - If the MIPS Coherence Manager (CM) reports an error then we'll now
           clear that error correctly so that the GCR_ERROR_CAUSE register
           will be updated with information about any future errors"

        There are multiple code fixes for older bugs, all of which should get

         - tango: one fix for multiplatform configurations broken on other

      blk-iolatency: fix IO hang due to negative inflight counter · 8c772a9b

      Our test reported the following stack, and vmcore showed that
      ->inflight counter is -1.

      [ffffc9003fcc3f50] entry_SYSCALL_64_after_swapgs at ffffffff81742b8e
      
      The ->inflight counter may be negative (-1) if
      
      1) blk-iolatency was disabled when the IO was issued,
      
      2) blk-iolatency was enabled before this IO reached its endio,
      
      3) the ->inflight counter is decreased from 0 to -1 in endio()
      
      In fact the hang can be easily reproduced by the below script,
      
      H=/sys/fs/cgroup/unified/
      P=/sys/fs/cgroup/unified/test
      
      echo "+io" > $H/cgroup.subtree_control
      mkdir -p $P
      
      echo $$ > $P/cgroup.procs
      
      xfs_io -f -d -c "pwrite 0 4k" /dev/sdg
      
      echo "`cat /sys/block/sdg/dev` target=1000000" > $P/io.latency
      
      xfs_io -f -d -c "pwrite 0 4k" /dev/sdg
      
      This fixes the problem by freezing the queue so that while
      enabling/disabling iolatency, there is no inflight rq running.
      
      Note that quiesce_queue is not needed as this only updating iolatency
      configuration about which dispatching request_queue doesn't care.

      In the linux kernel MAINTAINERS file, largely
        "xen-devel@lists.xenproject.org (moderated for non-subscribers)"
      is used to refer to the xen-devel mailing list.
      
      The DRM DRIVERS FOR XEN section entry mentions
      xen-devel@lists.xen.org instead, but that is just the same
      mailing list as the mailing list above.

      net: dsa: b53: Fix for failure when irq is not defined in dt · 39841cc1
      Arun Parameswaran authored
      Fixes the issues with non BCM58XX chips in the b53 driver
      failing, when the irq is not specified in the device tree.
      
      Removed the check for BCM58XX in b53_srab_prepare_irq(),
      so the 'port->irq' will be set to '-EXIO' if the irq is not
      specified in the device tree.
      
      Fixes: 16994374 ("net: dsa: b53: Make SRAB driver manage port interrupts")
      Fixes: b2ddc48a ("net: dsa: b53: Do not fail when IRQ are not initialized")
