      Pull io_uring fixes from Jens Axboe:
       "A bit of a mix between fallout from the worker change, cleanups and
        reductions now possible from that change, and fixes in general. In
        detail:
      
         - Fully serialize manager and worker creation, fixing races due to
           that.
      
         - Clean up some naming that had gone stale.
      
         - SQPOLL fixes.
      
         - Fix race condition around task_work rework that went into this
           merge window.
      
         - Implement unshare. Used for when the original task does unshare(2)
           or setuid/seteuid and friends, drops the original workers and forks
           new ones.
      
         - Drop the only remaining piece of state shuffling we had left, which
           was cred. Move it into issue instead, and we can drop all of that
           code too.
      
         - Kill f_op->flush() usage. That was such a nasty hack that we had
           out of necessity, we no longer need it.
      
         - Following from ->flush() removal, we can also drop various bits of
           ctx state related to SQPOLL and cancelations.
      
         - Fix an issue with IOPOLL retry, which originally was fallout from a
           filemap change (removing iov_iter_revert()), but uncovered an issue
           with iovec re-import too late.
      
         - Fix an issue with system suspend.
      
         - Use xchg() for fallback work, instead of cmpxchg().
      
         - Properly destroy io-wq on exec.
      
         - Add create_io_thread() core helper, and use that in io-wq and
           io_uring. This allows us to remove various silly completion events
           related to thread setup.
      
         - A few error handling fixes.
      
        This should be the grunt of fixes necessary for the new workers, next
        week should be quieter. We've got a pending series from Pavel on
        cancelations, and how tasks and rings are indexed. Outside of that,
        should just be minor fixes. Even with these fixes, we're still killing

      io_uring: make SQPOLL thread parking saner · 86e0d676
      Jens Axboe authored
      We have this weird true/false return from parking, and then some of the
      callers decide to look at that. It can lead to unbalanced parks and
      sqd locking. Have the callers check the thread status once it's parked.
      We know we have the lock at that point, so it's either valid or it's NULL.
      
      Fix race with parking on thread exit. We need to be careful here with
      ordering of the sdq->lock and the IO_SQ_THREAD_SHOULD_PARK bit.
      
      Rename sqd->completion to sqd->parked to reflect that this is the only
      thing this completion event doesn.

      io-wq: kill hashed waitqueue before manager exits · 09ca6c40
      Jens Axboe authored
      If we race with shutting down the io-wq context and someone queueing
      a hashed entry, then we can exit the manager with it armed. If it then
      triggers after the manager has exited, we can have a use-after-free where
      io_wqe_hash_wake() attempts to wake a now gone manager process.
      
      Move the killing of the hashed write queue into the manager itself, so
      that we know we've killed it before the task exits.

      The callback can only be armed, if we get -EIOCBQUEUED returned. It's

      nvmet: model_number must be immutable once set · d9f273b7
      Max Gurtovoy authored
      In case we have already established connection to nvmf target, it
      shouldn't be allowed to change the model_number. E.g. if someone will
      identify ctrl and get model_number of "my_model" later on will change
      the model_numbel via configfs to "my_new_model" this will break the NVMe
      specification for "Get Log Page – Persistent Event Log" that refers to
      Model Number as: "This field contains the same value as reported in the
      Model Number field of the Identify Controller data structure, bytes
      63:24."
      
      Although it doesn't mentioned explicitly that this field can't be
      changed, we can assume it.
      
      So allow setting this field only once: using configfs or in the first
      identify ctrl operation.

      nvme-fabrics: fix kato initialization · 32feb6de
      Martin George authored
      Currently kato is initialized to NVME_DEFAULT_KATO for both
      discovery & i/o controllers. This is a problem specifically
      for non-persistent discovery controllers since it always ends
      up with a non-zero kato value. Fix this by initializing kato
      to zero instead, and ensuring various controllers are assigned
      appropriate kato values as follows:
      
      non-persistent controllers  - kato set to zero
      persistent controllers      - kato set to NVMF_DEV_DISC_TMO
                                    (or any positive int via nvme-cli)
      i/o controllers             - kato set to NVME_DEFAULT_KATO
                                    (or any positive int via nvme-cli)

      Daniel Wagner authored
      The hwmon pointer wont be NULL if the registration fails. Though the
      exit code path will assign it to ctrl->hwmon_device. Later
      nvme_hwmon_exit() will try to free the invalid pointer. Avoid this by
      returning the error code from hwmon_device_register_with_info().

      nvme-pci: mark Kingston SKC2000 as not supporting the deepest power state · dc22c1c0
      Zoltán Böszörményi authored
      My 2TB SKC2000 showed the exact same symptoms that were provided
      in 538e4a8c ("nvme-pci: avoid the deepest sleep state on
      Kingston A2000 SSDs"), i.e. a complete NVME lockup that needed
      cold boot to get it back.
      
      According to some sources, the A2000 is simply a rebadged
      SKC2000 with a slightly optimized firmware.
      
      Adding the SKC2000 PCI ID to the quirk list with the same workaround
      as the A2000 made my laptop survive a 5 hours long Yocto bootstrap
      buildfest which reliably triggered the SSD lockup previously.

      Protect the iSCSI transport handle, available in sysfs, by requiring

      dm verity: fix FEC for RS roots unaligned to block size · df7b59ba
      Milan Broz authored
      Optional Forward Error Correction (FEC) code in dm-verity uses
      Reed-Solomon code and should support roots from 2 to 24.
      
      The error correction parity bytes (of roots lengths per RS block) are
      stored on a separate device in sequence without any padding.
      
      Currently, to access FEC device, the dm-verity-fec code uses dm-bufio
      client with block size set to verity data block (usually 4096 or 512
      bytes).
      
      Because this block size is not divisible by some (most!) of the roots
      supported lengths, data repair cannot work for partially stored parity
      bytes.
      
      This fix changes FEC device dm-bufio block size to "roots << SECTOR_SHIFT"
      where we can be sure that the full parity data is always available.
      (There cannot be partial FEC blocks because parity must cover whole
      sectors.)
      
      Because the optional FEC starting offset could be unaligned to this
      new block size, we have to use dm_bufio_set_sector_offset() to
      configure it.
      
      The problem is easily reproduced using veritysetup, e.g. for roots=13:
      
        # create verity device with RS FEC
        dd if=/dev/urandom of=data.img bs=4096 count=8 status=none
        veritysetup format data.img hash.img --fec-device=fec.img --fec-roots=13 | awk '/^Root hash/{ print $3 }' >roothash
      
        # create an erasure that should be always repairable with this roots setting
        dd if=/dev/zero of=data.img conv=notrunc bs=1 count=8 seek=4088 status=none
      
        # try to read it through dm-verity
        veritysetup open data.img test hash.img --fec-device=fec.img --fec-roots=13 $(cat roothash)
        dd if=/dev/mapper/test of=/dev/null bs=4096 status=noxfer
        # wait for possible recursive recovery in kernel
        udevadm settle
        veritysetup close test
      
      With this fix, errors are properly repaired.
        device-mapper: verity-fec: 7:1: FEC 0: corrected 8 errors
        ...
      
      Without it, FEC code usually ends on unrecoverable failure in RS decoder:
        device-mapper: verity-fec: 7:1: FEC 0: failed to correct: -74
        ...
      
      This problem is present in all kernels since the FEC code's
      introduction (kernel 4.5).
      
      It is thought that this problem is not visible in Android ecosystem
      because it always uses a default RS roots=2.

      dm bufio: subtract the number of initial sectors in dm_bufio_get_device_size · a14e5ec6
      Mikulas Patocka authored
      dm_bufio_get_device_size returns the device size in blocks. Before
      returning the value, we must subtract the nubmer of starting
      sectors. The number of starting sectors may not be divisible by block
      size.
      
      Note that currently, no target is using dm_bufio_set_sector_offset and
      dm_bufio_get_device_size simultaneously, so this change has no effect.
      However, an upcoming dm-verity-fec fix needs this change.
