      dm raid1: set discard_zeroes_data_unsupported · 7c8d3a42
      Mikulas Patocka 提交于
      We can't guarantee that REQ_DISCARD on dm-mirror zeroes the data even if
      the underlying disks support zero on discard.  So this patch sets
      ti->discard_zeroes_data_unsupported.
      
      For example, if the mirror is in the process of resynchronizing, it may
      happen that kcopyd reads a piece of data, then discard is sent on the
      same area and then kcopyd writes the piece of data to another leg.
      Consequently, the data is not zeroed.
      
      The flag was made available by commit 983c7db3
      (dm crypt: always disable discard_zeroes_data).

      dm thin: do not send discards to shared blocks · 650d2a06
      Mikulas Patocka 提交于
      When process_discard receives a partial discard that doesn't cover a
      full block, it sends this discard down to that block. Unfortunately, the
      block can be shared and the discard would corrupt the other snapshots
      sharing this block.
      
      This patch detects block sharing and ends the discard with success when
      sending it to the shared block.
      
      The above change means that if the device supports discard it can't be
      guaranteed that a discard request zeroes data. Therefore, we set
      ti->discard_zeroes_data_unsupported.
      
      Thin target discard support with this bug arrived in commit
      104655fd (dm thin: support discards).

      dm raid1: fix crash with mirror recovery and discard · 751f188d
      Mikulas Patocka 提交于
      This patch fixes a crash when a discard request is sent during mirror
      recovery.
      
      Firstly, some background.  Generally, the following sequence happens during
      mirror synchronization:
      - function do_recovery is called
      - do_recovery calls dm_rh_recovery_prepare
      - dm_rh_recovery_prepare uses a semaphore to limit the number
        simultaneously recovered regions (by default the semaphore value is 1,
        so only one region at a time is recovered)
      - dm_rh_recovery_prepare calls __rh_recovery_prepare,
        __rh_recovery_prepare asks the log driver for the next region to
        recover. Then, it sets the region state to DM_RH_RECOVERING. If there
        are no pending I/Os on this region, the region is added to
        quiesced_regions list. If there are pending I/Os, the region is not
        added to any list. It is added to the quiesced_regions list later (by
        dm_rh_dec function) when all I/Os finish.
      - when the region is on quiesced_regions list, there are no I/Os in
        flight on this region. The region is popped from the list in
        dm_rh_recovery_start function. Then, a kcopyd job is started in the
        recover function.
      - when the kcopyd job finishes, recovery_complete is called. It calls
        dm_rh_recovery_end. dm_rh_recovery_end adds the region to
        recovered_regions or failed_recovered_regions list (depending on
        whether the copy operation was successful or not).
      
      The above mechanism assumes that if the region is in DM_RH_RECOVERING
      state, no new I/Os are started on this region. When I/O is started,
      dm_rh_inc_pending is called, which increases reg->pending count. When
      I/O is finished, dm_rh_dec is called. It decreases reg->pending count.
      If the count is zero and the region was in DM_RH_RECOVERING state,
      dm_rh_dec adds it to the quiesced_regions list.
      
      Consequently, if we call dm_rh_inc_pending/dm_rh_dec while the region is
      in DM_RH_RECOVERING state, it could be added to quiesced_regions list
      multiple times or it could be added to this list when kcopyd is copying
      data (it is assumed that the region is not on any list while kcopyd does
      its jobs). This results in memory corruption and crash.
      
      There already exist bypasses for REQ_FLUSH requests: REQ_FLUSH requests
      do not belong to any region, so they are always added to the sync list
      in do_writes. dm_rh_inc_pending does not increase count for REQ_FLUSH
      requests. In mirror_end_io, dm_rh_dec is never called for REQ_FLUSH
      requests. These bypasses avoid the crash possibility described above.
      
      These bypasses were improperly implemented for REQ_DISCARD when
      the mirror target gained discard support in commit
      5fc2ffea (dm raid1: support discard).
      
      In do_writes, REQ_DISCARD requests is always added to the sync queue and
      immediately dispatched (even if the region is in DM_RH_RECOVERING).  However,
      dm_rh_inc and dm_rh_dec is called for REQ_DISCARD resusts.  So it violates the
      rule that no I/Os are started on DM_RH_RECOVERING regions, and causes the list
      corruption described above.
      
      This patch changes it so that REQ_DISCARD requests follow the same path
      as REQ_FLUSH. This avoids the crash.

      pnfs-obj: Fix __r4w_get_page when offset is beyond i_size · c999ff68
      Boaz Harrosh 提交于
      It is very common for the end of the file to be unaligned on
      stripe size. But since we know it's beyond file's end then
      the XOR should be preformed with all zeros.
      
      Old code used to just read zeros out of the OSD devices, which is a great
      waist. But what scares me more about this situation is that, we now have
      pages attached to the file's mapping that are beyond i_size. I don't
      like the kind of bugs this calls for.
      
      Fix both birds, by returning a global zero_page, if offset is beyond
      i_size.
      
      TODO:
      	Change the API to ->__r4w_get_page() so a NULL can be

      ore: Fix NFS crash by supporting any unaligned RAID IO · 9ff19309
      Boaz Harrosh 提交于
      In RAID_5/6 We used to not permit an IO that it's end
      byte is not stripe_size aligned and spans more than one stripe.
      .i.e the caller must check if after submission the actual
      transferred bytes is shorter, and would need to resubmit
      a new IO with the remainder.
      
      Exofs supports this, and NFS was supposed to support this
      as well with it's short write mechanism. But late testing has
      exposed a CRASH when this is used with none-RPC layout-drivers.
      
      The change at NFS is deep and risky, in it's place the fix
      at ORE to lift the limitation is actually clean and simple.
      So here it is below.
      
      The principal here is that in the case of unaligned IO on
      both ends, beginning and end, we will send two read requests
      one like old code, before the calculation of the first stripe,
      and also a new site, before the calculation of the last stripe.
      If any "boundary" is aligned or the complete IO is within a single
      stripe. we do a single read like before.
      
      The code is clean and simple by splitting the old _read_4_write
      into 3 even parts:
      1._read_4_write_first_stripe
      2. _read_4_write_last_stripe
      3. _read_4_write_execute
      
      And calling 1+3 at the same place as before. 2+3 before last
      stripe, and in the case of all in a single stripe then 1+2+3
      is preformed additively.
      
      Why did I not think of it before. Well I had a strike of
      genius because I have stared at this code for 2 years, and did
      not find this simple solution, til today. Not that I did not try.
      
      This solution is much better for NFS than the previous supposedly
      solution because the short write was dealt  with out-of-band after
      IO_done, which would cause for a seeky IO pattern where as in here
      we execute in order. At both solutions we do 2 separate reads, only
      here we do it within a single IO request. (And actually combine two
      writes into a single submission)
      
      NFS/exofs code need not change since the ORE API communicates the new
      shorter length on return, what will happen is that this case would not
      occur anymore.
      
      hurray!!

      UBIFS: fix a bug in empty space fix-up · c6727932
      Artem Bityutskiy 提交于
      UBIFS has a feature called "empty space fix-up" which is a quirk to work-around
      limitations of dumb flasher programs. Namely, of those flashers that are unable
      to skip NAND pages full of 0xFFs while flashing, resulting in empty space at
      the end of half-filled eraseblocks to be unusable for UBIFS. This feature is
      relatively new (introduced in v3.0).
      
      The fix-up routine (fixup_free_space()) is executed only once at the very first
      mount if the superblock has the 'space_fixup' flag set (can be done with -F
      option of mkfs.ubifs). It basically reads all the UBIFS data and metadata and
      writes it back to the same LEB. The routine assumes the image is pristine and
      does not have anything in the journal.
      
      There was a bug in 'fixup_free_space()' where it fixed up the log incorrectly.
      All but one LEB of the log of a pristine file-system are empty. And one
      contains just a commit start node. And 'fixup_free_space()' just unmapped this
      LEB, which resulted in wiping the commit start node. As a result, some users
      were unable to mount the file-system next time with the following symptom:
      
      UBIFS error (pid 1): replay_log_leb: first log node at LEB 3:0 is not CS node
      UBIFS error (pid 1): replay_log_leb: log error detected while replaying the log at LEB 3:0
      
      The root-cause of this bug was that 'fixup_free_space()' wrongly assumed
      that the beginning of empty space in the log head (c->lhead_offs) was known
      on mount. However, it is not the case - it was always 0. UBIFS does not store
      in it the master node and finds out by scanning the log on every mount.
      
      The fix is simple - just pass commit start node size instead of 0 to
      'fixup_leb()'.

      cx25821: Remove bad strcpy to read-only char* · 380e99fc
      Ezequiel Garcia 提交于
      The strcpy was being used to set the name of the board.  Since the
      destination char* was read-only and the name is set statically at
      compile time; this was both wrong and redundant.
      
      The type of char* is changed to const char* to prevent future errors.

      MIPS: PCI: Move fixups from __init to __devinit. · 85a053fa
      Sebastian Andrzej Siewior 提交于
      Fixups are executed once the pci-device is found which is during boot
      process so __init seems fine as long as the platform does not support
      hotplug.
      However it is possible to remove the PCI bus at run time and have it
      rediscovered again via "echo 1 > /sys/bus/pci/rescan" and this will call
      the fixups again.
