      Charles Machalow authored
      Changing nvme_passthru_cmd64 to add a field: rsvd2. This field is an explicit
      marker for the padding space added on certain platforms as a result of the
      enlargement of the result field from 32 bit to 64 bits in size, and
      fixes differences in struct size when using compat ioctl for 32-bit
      binaries on 64-bit architecture.

      nvme-multipath: fix crash in nvme_mpath_clear_ctrl_paths · 763303a8
      Anton Eidelman authored
      nvme_mpath_clear_ctrl_paths() iterates through
      the ctrl->namespaces list while holding ctrl->scan_lock.
      This does not seem to be the correct way of protecting
      from concurrent list modification.
      
      Specifically, nvme_scan_work() sorts ctrl->namespaces
      AFTER unlocking scan_lock.
      
      This may result in the following (rare) crash in ctrl disconnect
      during scan_work:

      Fix:
      After taking scan_lock in nvme_mpath_clear_ctrl_paths()
      down_read(&ctrl->namespaces_rwsem) as well to make list traversal safe.
      This will not cause deadlocks because taking scan_lock never happens
      while holding the namespaces_rwsem.
      Moreover, scan work downs namespaces_rwsem in the same order.
      
      Alternative: sort ctrl->namespaces in nvme_scan_work()
      while still holding the scan_lock.
      This would leave nvme_mpath_clear_ctrl_paths() without correct protection
      against ctrl->namespaces modification by anyone other than scan_work.

      Max Gurtovoy authored
      In case there are controllers that are not associated with any RDMA
      device (e.g. during unsuccessful reconnection) and the user will unload
      the module, these controllers will not be freed and will access already
      freed memory. The same logic appears in other fabric drivers as well.

      io_uring: ensure we clear io_kiocb->result before each issue · 6873e0bd
      Jens Axboe authored
      We use io_kiocb->result == -EAGAIN as a way to know if we need to
      re-submit a polled request, as -EAGAIN reporting happens out-of-line
      for IO submission failures. This field is cleared when we originally
      allocate the request, but it isn't reset when we retry the submission
      from async context. This can cause issues where we think something
      needs a re-issue, but we're really just reading stale data.
      
      Reset ->result whenever we re-prep a request for polled submission.

      nvme-multipath: fix possible io hang after ctrl reconnect · af8fd042
      Anton Eidelman authored
      The following scenario results in an IO hang:
      1) ctrl completes a request with NVME_SC_ANA_TRANSITION.
         NVME_NS_ANA_PENDING bit in ns->flags is set and ana_work is triggered.
      2) ana_work: nvme_read_ana_log() tries to get the ANA log page from the ctrl.
         This fails because ctrl disconnects.
         Therefore nvme_update_ns_ana_state() is not called
         and NVME_NS_ANA_PENDING bit in ns->flags is not cleared.
      3) ctrl reconnects: nvme_mpath_init(ctrl,...) calls
         nvme_read_ana_log(ctrl, groups_only=true).
         However, nvme_update_ana_state() does not update namespaces
         because nr_nsids = 0 (due to groups_only mode).
      4) scan_work calls nvme_validate_ns() finds the ns and re-validates OK.
      
      Result:
      The ctrl is now live but NVME_NS_ANA_PENDING bit in ns->flags is still set.
      Consequently ctrl will never be considered a viable path by __nvme_find_path().
      IO will hang if ctrl is the only or the last path to the namespace.
      
      More generally, while ctrl is reconnecting, its ANA state may change.
      And because nvme_mpath_init() requests ANA log in groups_only mode,
      these changes are not propagated to the existing ctrl namespaces.
      This may result in a mal-function or an IO hang.
      
      Solution:
      nvme_mpath_init() will nvme_read_ana_log() with groups_only set to false.
      This will not harm the new ctrl case (no namespaces present),
      and will make sure the ANA state of namespaces gets updated after reconnect.
      
      Note: Another option would be for nvme_mpath_init() to invoke
      nvme_parse_ana_log(..., nvme_set_ns_ana_state) for each existing namespace.

      nbd: verify socket is supported during setup · cf1b2326
      Mike Christie authored
      nbd requires socket families to support the shutdown method so the nbd
      recv workqueue can be woken up from its sock_recvmsg call. If the socket
      does not support the callout we will leave recv works running or get hangs
      later when the device or module is removed.
      
      This adds a check during socket connection/reconnection to make sure the
      socket being passed in supports the needed callout.

      ata: libahci_platform: Fix regulator_get_optional() misuse · 962399bb
      Mark Brown authored
      This driver is using regulator_get_optional() to handle all the supplies
      that it handles, and only ever enables and disables all supplies en masse
      without ever doing any other configuration of the device to handle missing
      power. These are clear signs that the API is being misused - it should only
      be used for supplies that may be physically absent from the system and in
      these cases the hardware usually needs different configuration if the
      supply is missing. Instead use normal regualtor_get(), if the supply is
      not described in DT then the framework will substitute a dummy regulator in
      so no special handling is needed by the consumer driver.
      
      In the case of the PHY regulator the handling in the driver is a hack to
      deal with integrated PHYs; the supplies are only optional in the sense
      that that there's some confusion in the code about where they're bound to.
      From a code point of view they function exactly as normal supplies so can
      be treated as such. It'd probably be better to model this by instantiating
      a PHY object for integrated PHYs.

      This was preceded by us timing out everything and shutting down the
      sockets for the device.  The problem is we had a request in the queue at
      the same time, so we completed the request twice.  This can actually
      happen in a lot of cases, we fail to get a ref on our config, we only
      have one connection and just error out the command, etc.
      
      Fix this by checking cmd->status in nbd_read_stat.  We only change this
      under the cmd->lock, so we are safe to check this here and see if we've
      already error'ed this command out, which would indicate that we've
      completed it as well.

      nbd: protect cmd->status with cmd->lock · de6346ec
      Josef Bacik authored
      We already do this for the most part, except in timeout and clear_req.
      For the timeout case we take the lock after we grab a ref on the config,
      but that isn't really necessary because we're safe to touch the cmd at
      this point, so just move the order around.
      
      For the clear_req cause this is initiated by the user, so again is safe.

      Pull modules fixes from Jessica Yu:
      
       - Revert __ksymtab_$namespace.$symbol naming scheme back to
         __ksymtab_$symbol, as it was causing issues with depmod.
      
         Instead, have modpost extract a symbol's namespace from __kstrtabns
         and __ksymtab_strings.
      
       - Fix `make nsdeps` for out of tree kernel builds (make O=...) caused
         by unescaped '/'.
      
         Use a different sed delimiter to avoid this problem.

      Pull ARM SoC fixes from Olof Johansson:
       "A slightly larger set of fixes have accrued in the last two weeks.
        Mostly a collection of the usual smaller fixes:
      
         - Marvell Armada: USB phy setup issues on Turris Mox
      
         - Broadcom: GPIO/pinmux DT mapping corrections for Stingray, MMC bus
           width fix for RPi Zero W, GPIO LED removal for RPI CM3. Also some
           maintainer updates.
      
         - OMAP: Fixlets for display config, interrupt settings for wifi, some
           clock/PM pieces. Also IOMMU regression fix and a ti-sysc
           no-watchdog regression fix.
      
         - i.MX: A few fixes around PM/settings, some devicetree fixlets and
           catching up with config option changes in DRM
      
         - Rockchip: RockRro64 misc DT fixups, Hugsun X99 USB-C, Kevin display
           panel settings
      
        ... and some smaller fixes for Davinci (backlight, McBSP DMA),
