      nvme-multipath: fix possible io hang after ctrl reconnect · af8fd042
      Anton Eidelman 提交于
      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 提交于
      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 提交于
      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 提交于
      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.

      io_uring: fix bad inflight accounting for SETUP_IOPOLL|SETUP_SQTHREAD · 2b2ed975
      Jens Axboe 提交于
      We currently assume that submissions from the sqthread are successful,
      and if IO polling is enabled, we use that value for knowing how many
      completions to look for. But if we overflowed the CQ ring or some
      requests simply got errored and already completed, they won't be
      available for polling.
      
      For the case of IO polling and SQTHREAD usage, look at the pending
      poll list. If it ever hits empty then we know that we don't have
      anymore pollable requests inflight. For that case, simply reset
      the inflight count to zero.

      Created in-kernel cached versions of them, and just overwrite the user
