      xfs: di_flushiter considered harmful · e1b4271a
      Dave Chinner authored
      When we made all inode updates transactional, we no longer needed
      the log recovery detection for inodes being newer on disk than the
      transaction being replayed - it was redundant as replay of the log
      would always result in the latest version of the inode would be on
      disk. It was redundant, but left in place because it wasn't
      considered to be a problem.
      
      However, with the new "don't read inodes on create" optimisation,
      flushiter has come back to bite us. Essentially, the optimisation
      made always initialises flushiter to zero in the create transaction,
      and so if we then crash and run recovery and the inode already on
      disk has a non-zero flushiter it will skip recovery of that inode.
      As a result, log recovery does the wrong thing and we end up with a
      corrupt filesystem.
      
      Because we have to support old kernel to new kernel upgrades, we
      can't just get rid of the flushiter support in log recovery as we
      might be upgrading from a kernel that doesn't have fully transactional
      inode updates.  Unfortunately, for v4 superblocks there is no way to
      guarantee that log recovery knows about this fact.
      
      We cannot add a new inode format flag to say it's a "special inode
      create" because it won't be understood by older kernels and so
      recovery could do the wrong thing on downgrade. We cannot specially
      detect the combination of zero mode/non-zero flushiter on disk to
      non-zero mode, zero flushiter in the log item during recovery
      because wrapping of the flushiter can result in false detection.
      
      Hence that makes this "don't use flushiter" optimisation limited to
      a disk format that guarantees that we don't need it. And that means
      the only fix here is to limit the "no read IO on create"
      optimisation to version 5 superblocks....

      md/raid5: fix interaction of 'replace' and 'recovery'. · f94c0b66
      NeilBrown authored
      If a device in a RAID4/5/6 is being replaced while another is being
      recovered, then the writes to the replacement device currently don't
      happen, resulting in corruption when the replacement completes and the
      new drive takes over.
      
      This is because the replacement writes are only triggered when
      's.replacing' is set and not when the similar 's.sync' is set (which
      is the case during resync and recovery - it means all devices need to
      be read).
      
      So schedule those writes when s.replacing is set as well.
      
      In this case we cannot use "STRIPE_INSYNC" to record that the
      replacement has happened as that is needed for recording that any
      parity calculation is complete.  So introduce STRIPE_REPLACED to
      record if the replacement has happened.
      
      For safety we should also check that STRIPE_COMPUTE_RUN is not set.
      This has a similar effect to the "s.locked == 0" test.  The latter
      ensure that now IO has been flagged but not started.  The former
      checks if any parity calculation has been flagged by not started.
      We must wait for both of these to complete before triggering the
      'replace'.
      
      Add a similar test to the subsequent check for "are we finished yet".
      This possibly isn't needed (is subsumed in the STRIPE_INSYNC test),
      but it makes it more obvious that the REPLACE will happen before we
      think we are finished.
      
      Finally if a NeedReplace device is not UPTODATE then that is an
      error.  We really must trigger a warning.
      
      This bug was introduced in commit 9a3e1101
      (md/raid5:  detect and handle replacements during recovery.)
      which introduced replacement for raid5.
      That was in 3.3-rc3, so any stable kernel since then would benefit
      from this fix.

      md/raid10: remove use-after-free bug. · 0eb25bb0
      NeilBrown authored
      We always need to be careful when calling generic_make_request, as it
      can start a chain of events which might free something that we are
      using.
      
      Here is one place I wasn't careful enough.  If the wbio2 is not in
      use, then it might get freed at the first generic_make_request call.
      So perform all necessary tests first.
      
      This bug was introduced in 3.3-rc3 (24afd80d) and can cause an
      oops, so fix is suitable for any -stable since then.
