      dm thin: send event about thin-pool state change _after_ making it · cd5d8a92
      Mike Snitzer authored
      commit f6c36758
      
       upstream.
      
      Sending a DM event before a thin-pool state change is about to happen is
      a bug.  It wasn't realized until it became clear that userspace response
      to the event raced with the actual state change that the event was
      meant to notify about.
      
      Fix this by first updating internal thin-pool state to reflect what the
      DM event is being issued about.  This fixes a long-standing racey/buggy
      userspace device-mapper-test-suite 'resize_io' test that would get an
      event but not find the state it was looking for -- so it would just go
      on to hang because no other events caused the test to reevaluate the
      thin-pool's state.

      dm cache: fix resize crash if user doesn't reload cache table · ec6ae632
      Mike Snitzer authored
      commit 5d07384a upstream.
      
      A reload of the cache's DM table is needed during resize because
      otherwise a crash will occur when attempting to access smq policy
      entries associated with the portion of the cache that was recently
      extended.
      
      The reason is cache-size based data structures in the policy will not be
      resized, the only way to safely extend the cache is to allow for a
      proper cache policy initialization that occurs when the cache table is
      loaded.  For example the smq policy's space_init(), init_allocator(),
      calc_hotspot_params() must be sized based on the extended cache size.
      
      The fix for this is to disallow cache resizes of this pattern:
      1) suspend "cache" target's device
      2) resize the fast device used for the cache
      3) resume "cache" target's device
      
      Instead, the last step must be a full reload of the cache's DM table.

      dm cache metadata: ignore hints array being too small during resize · f11a6abf
      Joe Thornber authored
      commit 4561ffca upstream.
      
      Commit fd2fa954 ("dm cache metadata: save in-core policy_hint_size to
      on-disk superblock") enabled previously written policy hints to be
      used after a cache is reactivated.  But in doing so the cache
      metadata's hint array was left exposed to out of bounds access because
      on resize the metadata's on-disk hint array wasn't ever extended.
      
      Fix this by ignoring that there are no on-disk hints associated with the
      newly added cache blocks.  An expanded on-disk hint array is later
      rewritten upon the next clean shutdown of the cache.
      
      Fixes: fd2fa954

      dm cache: only allow a single io_mode cache feature to be requested · e85940a5
      John Pittman authored
      [ Upstream commit af9313c3 ]
      
      More than one io_mode feature can be requested when creating a dm cache
      device (as is: last one wins).  The io_mode selections are incompatible
      with one another, we should force them to be selected exclusively.  Add
      a counter to check for more than one io_mode selection.

      md/raid5: fix data corruption of replacements after originals dropped · d1060bfc
      BingJing Chang authored
      [ Upstream commit d63e2fc8 ]
      
      During raid5 replacement, the stripes can be marked with R5_NeedReplace
      flag. Data can be read from being-replaced devices and written to
      replacing spares without reading all other devices. (It's 'replace'
      mode. s.replacing = 1) If a being-replaced device is dropped, the
      replacement progress will be interrupted and resumed with pure recovery
      mode. However, existing stripes before being interrupted cannot read
      from the dropped device anymore. It prints lots of WARN_ON messages.
      And it results in data corruption because existing stripes write
      problematic data into its replacement device and update the progress.
      
      \# Erase disks (1MB + 2GB)
      dd if=/dev/zero of=/dev/sda bs=1MB count=2049
      dd if=/dev/zero of=/dev/sdb bs=1MB count=2049
      dd if=/dev/zero of=/dev/sdc bs=1MB count=2049
      dd if=/dev/zero of=/dev/sdd bs=1MB count=2049
      mdadm -C /dev/md0 -amd -R -l5 -n3 -x0 /dev/sd[abc] -z 2097152
      \# Ensure array stores non-zero data
      dd if=/root/data_4GB.iso of=/dev/md0 bs=1MB
      \# Start replacement
      mdadm /dev/md0 -a /dev/sdd
      mdadm /dev/md0 --replace /dev/sda
      
      Then, Hot-plug out /dev/sda during recovery, and wait for recovery done.
      echo check > /sys/block/md0/md/sync_action
      cat /sys/block/md0/md/mismatch_cnt # it will be greater than 0.
      
      Soon after you hot-plug out /dev/sda, you will see many WARN_ON
      messages. The replacement recovery will be interrupted shortly. After
      the recovery finishes, it will result in data corruption.
      
      Actually, it's just an unhandled case of replacement. In commit
      <f94c0b66> (md/raid5: fix interaction of 'replace' and 'recovery'.),
      if a NeedReplace device is not UPTODATE then that is an error, the
      commit just simply print WARN_ON but also mark these corrupted stripes
      with R5_WantReplace. (it means it's ready for writes.)
      
      To fix this case, we can leverage 'sync and replace' mode mentioned in
      commit <9a3e1101
      
      > (md/raid5: detect and handle replacements during
      recovery.). We can add logics to detect and use 'sync and replace' mode
      for these stripes.

      It was reported that softlockups occur when using dm-snapshot ontop of

      dm cache metadata: set dirty on all cache blocks after a crash · f961be89
      Ilya Dryomov authored
      commit 5b1fe7be upstream.
      
      Quoting Documentation/device-mapper/cache.txt:
      
        The 'dirty' state for a cache block changes far too frequently for us
        to keep updating it on the fly.  So we treat it as a hint.  In normal
        operation it will be written when the dm device is suspended.  If the
        system crashes all cache blocks will be assumed dirty when restarted.
      
      This got broken in commit f177940a ("dm cache metadata: switch to
      using the new cursor api for loading metadata") in 4.9, which removed
      the code that consulted cmd->clean_when_opened (CLEAN_SHUTDOWN on-disk
      flag) when loading cache blocks.  This results in data corruption on an
      unclean shutdown with dirty cache blocks on the fast device.  After the
      crash those blocks are considered clean and may get evicted from the
      cache at any time.  This can be demonstrated by doing a lot of reads
      to trigger individual evictions, but uncache is more predictable:
      
        ### Disable auto-activation in lvm.conf to be able to do uncache in
        ### time (i.e. see uncache doing flushing) when the fix is applied.

      dm cache metadata: save in-core policy_hint_size to on-disk superblock · b7227e60
      Mike Snitzer authored
      commit fd2fa954
      
       upstream.
      
      policy_hint_size starts as 0 during __write_initial_superblock().  It
      isn't until the policy is loaded that policy_hint_size is set in-core
      (cmd->policy_hint_size).  But it never got recorded in the on-disk
      superblock because __commit_transaction() didn't deal with transfering
      the in-core cmd->policy_hint_size to the on-disk superblock.
      
      The in-core cmd->policy_hint_size gets initialized by metadata_open()'s
      __begin_transaction_flags() which re-reads all superblock fields.
      Because the superblock's policy_hint_size was never properly stored, when
      the cache was created, hints_array_available() would always return false
      when re-activating a previously created cache.  This means
      __load_mappings() always considered the hints invalid and never made use
      of the hints (these hints served to optimize).
      
      Another detremental side-effect of this oversight is the cache_check
      utility would fail with: "invalid hint width: 0"

      dm thin: stop no_space_timeout worker when switching to write-mode · 3bef8825

      commit 75294442 upstream.
      
      Now both check_for_space() and do_no_space_timeout() will read & write
      pool->pf.error_if_no_space.  If these functions run concurrently, as
      shown in the following case, the default setting of "queue_if_no_space"
      can get lost.
      
      precondition:
          * error_if_no_space = false (aka "queue_if_no_space")
          * pool is in Out-of-Data-Space (OODS) mode
          * no_space_timeout worker has been queued
      
      CPU 0:                          CPU 1:
      // delete a thin device
      process_delete_mesg()
      // check_for_space() invoked by commit()
      set_pool_mode(pool, PM_WRITE)
          pool->pf.error_if_no_space = \
           pt->requested_pf.error_if_no_space
      
      				// timeout, pool is still in OODS mode
      				do_no_space_timeout
      				    // "queue_if_no_space" config is lost
      				    pool->pf.error_if_no_space = true
          pool->pf.mode = new_mode
      
      Fix it by stopping no_space_timeout worker when switching to write mode.

       upstream.
      
      Early alpha processors can't write a byte or short atomically - they
      read 8 bytes, modify the byte or two bytes in registers and write back
      8 bytes.
      
      The modification of the variable "suspending" may race with
      modification of the variable "failed".  Fix this by changing
      "suspending" to an int.

      For raid6, when two disk of the array are offline, two spare disks can
      be added into the array. Before spare disks recovery completing,
      system reboot and mdadm thinks it is ok to restart the degraded
      array by md_ioctl(). Since disks in raid6 is not only_parity(),
      raid5_run() will abort, when there is no PPL feature or not setting
      'start_dirty_degraded' parameter. Therefore, mddev->pers is NULL.
      
      But, mddev->raid_disks has been set and it will not be cleared when
      raid5_run abort. md_ioctl() can execute cmd 'HOT_REMOVE_DISK' to
      remove a disk by mdadm, which will cause NULL pointer dereference
      in remove_and_add_spares() finally.

      md/raid1: add error handling of read error from FailFast device · 1b3433cf
      Gioh Kim authored
      [ Upstream commit b33d1062
      
       ]
      
      Current handle_read_error() function calls fix_read_error()
      only if md device is RW and rdev does not include FailFast flag.
      It does not handle a read error from a RW device including
      FailFast flag.
      
      I am not sure it is intended. But I found that write IO error
      sets rdev faulty. The md module should handle the read IO error and
      write IO error equally. So I think read IO error should set rdev faulty.
