      md: add sysfs entries for PPL · 664aed04
      Artur Paszkiewicz authored
      Add 'consistency_policy' attribute for array. It indicates how the array
      maintains consistency in case of unexpected shutdown.
      
      Add 'ppl_sector' and 'ppl_size' for rdev, which describe the location
      and size of the PPL space on the device. They can't be changed for
      active members if the array is started and PPL is enabled, so in the
      setter functions only basic checks are performed. More checks are done
      in ppl_validate_rdev() when starting the log.
      
      These attributes are writable to allow enabling PPL for external
      metadata arrays and (later) to enable/disable PPL for a running array.

      raid5-ppl: Partial Parity Log write logging implementation · 3418d036
      Artur Paszkiewicz authored
      Implement the calculation of partial parity for a stripe and PPL write
      logging functionality. The description of PPL is added to the
      documentation. More details can be found in the comments in raid5-ppl.c.
      
      Attach a page for holding the partial parity data to stripe_head.
      Allocate it only if mddev has the MD_HAS_PPL flag set.
      
      Partial parity is the xor of not modified data chunks of a stripe and is
      calculated as follows:
      
      - reconstruct-write case:
        xor data from all not updated disks in a stripe
      
      - read-modify-write case:
        xor old data and parity from all updated disks in a stripe
      
      Implement it using the async_tx API and integrate into raid_run_ops().
      It must be called when we still have access to old data, so do it when
      STRIPE_OP_BIODRAIN is set, but before ops_run_prexor5(). The result is
      stored into sh->ppl_page.
      
      Partial parity is not meaningful for full stripe write and is not stored
      in the log or used for recovery, so don't attempt to calculate it when
      stripe has STRIPE_FULL_WRITE.
      
      Put the PPL metadata structures to md_p.h because userspace tools
      (mdadm) will also need to read/write PPL.
      
      Warn about using PPL with enabled disk volatile write-back cache for
      now. It can be removed once disk cache flushing before writing PPL is
      implemented.

      md/r5cache: improve recovery with read ahead page pool · effe6ee7
      Song Liu authored
      In r5cache recovery, the journal device is scanned page by page.
      Currently, we use sync_page_io() to read journal device. This is
      not efficient when we have to recovery many stripes from the journal.
      
      To improve the speed of recovery, this patch introduces a read ahead
      page pool (ra_pool) to recovery_ctx. With ra_pool, multiple consecutive
      pages are read in one IO. Then the recovery code read the journal from
      ra_pool.
      
      With ra_pool, r5l_recovery_ctx has become much bigger. Therefore,
      r5l_recovery_log() is refactored so r5l_recovery_ctx is not using
      stack space.

      md/raid5: sort bios · aaf9f12e
      Shaohua Li authored
      Previous patch (raid5: only dispatch IO from raid5d for harddisk raid)
      defers IO dispatching. The goal is to create better IO pattern. At that
      time, we don't sort the deffered IO and hope the block layer can do IO
      merge and sort. Now the raid5-cache writeback could create large amount
      of bios. And if we enable muti-thread for stripe handling, we can't
      control when to dispatch IO to raid disks. In a lot of time, we are
      dispatching IO which block layer can't do merge effectively.
      
      This patch moves further for the IO dispatching defer. We accumulate
      bios, but we don't dispatch all the bios after a threshold is met. This
      'dispatch partial portion of bios' stragety allows bios coming in a
      large time window are sent to disks together. At the dispatching time,
      there is large chance the block layer can merge the bios. To make this
      more effective, we dispatch IO in ascending order. This increases
      request merge chance and reduces disk seek.

      md/raid5-cache: bump flush stripe batch size · 84890c03
      Shaohua Li authored
      Bump the flush stripe batch size to 2048. For my 12 disks raid
      array, the stripes takes:
      12 * 4k * 2048 = 96MB
      
      This is still quite small. A hardware raid card generally has 1GB size,
      which we suggest the raid5-cache has similar cache size.
      
      The advantage of a big batch size is we can dispatch a lot of IO in the
      same time, then we can do some scheduling to make better IO pattern.
      
      Last patch prioritizes stripes, so we don't worry about a big flush
      stripe batch will starve normal stripes.

      md/raid5: prioritize stripes for writeback · 535ae4eb
      Shaohua Li authored
      In raid5-cache writeback mode, we have two types of stripes to handle.
      - stripes which aren't cached yet
      - stripes which are cached and flushing out to raid disks
      
      Upperlayer is more sensistive to latency of the first type of stripes
      generally. But we only one handle list for all these stripes, where the
      two types of stripes are mixed together. When reclaim flushes a lot of
      stripes, the first type of stripes could be noticeably delayed. On the
      other hand, if the log space is tight, we'd like to handle the second
      type of stripes faster and free log space.
      
      This patch destinguishes the two types stripes. They are added into
      different handle list. When we try to get a stripe to handl, we prefer
      the first type of stripes unless log space is tight.
      
      This should have no impact for !writeback case.

      md-cluster: add the support for resize · 818da59f
      Guoqing Jiang authored
      To update size for cluster raid, we need to make
      sure all nodes can perform the change successfully.
      However, it is possible that some of them can't do
      it due to failure (bitmap_resize could fail). So
      we need to consider the issue before we set the
      capacity unconditionally, and we use below steps
      to perform sanity check.
      
      1. A change the size, then broadcast METADATA_UPDATED
         msg.
      2. B and C receive METADATA_UPDATED change the size
         excepts call set_capacity, sync_size is not update
         if the change failed. Also call bitmap_update_sb
         to sync sb to disk.
      3. A checks other node's sync_size, if sync_size has
         been updated in all nodes, then send CHANGE_CAPACITY
         msg otherwise send msg to revert previous change.
      4. B and C call set_capacity if receive CHANGE_CAPACITY
         msg, otherwise pers->resize will be called to restore
         the old value.

      md-cluster: introduce cluster_check_sync_size · b98938d1
      Guoqing Jiang authored
      Support resize is a little complex for clustered
      raid, since we need to ensure all the nodes share
      the same knowledge about the size of raid.
      
      We achieve the goal by check the sync_size which
      is in each node's bitmap, we can only change the
      capacity after cluster_check_sync_size returns 0.
      
      Also, get_bitmap_from_slot is added to get a slot's
      bitmap. And we exported some funcs since they are
      used in cluster_check_sync_size().
      
      We can also reuse get_bitmap_from_slot to remove
      redundant code existed in bitmap_copy_from_slot.

      md-cluster: use sync way to handle METADATA_UPDATED msg · 0ba95977
      Guoqing Jiang authored
      Previously, when node received METADATA_UPDATED msg, it just
      need to wakeup mddev->thread, then md_reload_sb will be called
      eventually.
      
      We taken the asynchronous way to avoid a deadlock issue, the
      deadlock issue could happen when one node is receiving the
      METADATA_UPDATED msg (wants reconfig_mutex) and trying to run
      the path:
      
      md_check_recovery -> mddev_trylock(hold reconfig_mutex)
                        -> md_update_sb-metadata_update_start
      		     (want EX on token however token is
      		      got by the sending node)
      
      Since we will support resizing for clustered raid, and we
      need the metadata update handling to be synchronous so that
      the initiating node can detect failure, so we need to change
      the way for handling METADATA_UPDATED msg.
      
      But, we obviously need to avoid above deadlock with the
      sync way. To make this happen, we considered to not hold
      reconfig_mutex to call md_reload_sb, if some other thread
      has already taken reconfig_mutex and waiting for the 'token',
      then process_recvd_msg() can safely call md_reload_sb()
      without taking the mutex. This is because we can be certain
      that no other thread will take the mutex, and we also certain
      that the actions performed by md_reload_sb() won't interfere
      with anything that the other thread is in the middle of.
      
      To make this more concrete, we added a new cinfo->state bit
              MD_CLUSTER_HOLDING_MUTEX_FOR_RECVD
      
      Which is set in lock_token() just before dlm_lock_sync() is
      called, and cleared just after. As lock_token() is always
      called with reconfig_mutex() held (the specific case is the
      resync_info_update which is distinguished well in previous
      patch), if process_recvd_msg() finds that the new bit is set,
      then the mutex must be held by some other thread, and it will
      keep waiting.
      
      So process_metadata_update() can call md_reload_sb() if either
      mddev_trylock() succeeds, or if MD_CLUSTER_HOLDING_MUTEX_FOR_RECVD
      is set. The tricky bit is what to do if neither of these apply.
      We need to wait. Fortunately mddev_unlock() always calls wake_up()
      on mddev->thread->wqueue. So we can get lock_token() to call
      wake_up() on that when it sets the bit.
      
      There are also some related changes inside this commit:
      1. remove RELOAD_SB related codes since there are not valid anymore.
      2. mddev is added into md_cluster_info then we can get mddev inside
         lock_token.
      3. add new parameter for lock_token to distinguish reconfig_mutex
         is held or not.
      
      And, we need to set MD_CLUSTER_HOLDING_MUTEX_FOR_RECVD in below:
      1. set it before unregister thread, otherwise a deadlock could
         appear if stop a resyncing array.
         This is because md_unregister_thread(&cinfo->recv_thread) is
         blocked by recv_daemon -> process_recvd_msg
      			  -> process_metadata_update.
         To resolve the issue, MD_CLUSTER_HOLDING_MUTEX_FOR_RECVD is
         also need to be set before unregister thread.
      2. set it in metadata_update_start to fix another deadlock.
      	a. Node A sends METADATA_UPDATED msg (held Token lock).
      	b. Node B wants to do resync, and is blocked since it can't
      	   get Token lock, but MD_CLUSTER_HOLDING_MUTEX_FOR_RECVD is
      	   not set since the callchain
      	   (md_do_sync -> sync_request
              	       -> resync_info_update
      		       -> sendmsg
      		       -> lock_comm -> lock_token)
      	   doesn't hold reconfig_mutex.
      	c. Node B trys to update sb (held reconfig_mutex), but stopped
      	   at wait_event() in metadata_update_start since we have set
      	   MD_CLUSTER_SEND_LOCK flag in lock_comm (step 2).
      	d. Then Node B receives METADATA_UPDATED msg from A, of course
      	   recv_daemon is blocked forever.
         Since metadata_update_start always calls lock_token with reconfig_mutex,
         we need to set MD_CLUSTER_HOLDING_MUTEX_FOR_RECVD here as well, and
         lock_token don't need to set it twice unless lock_token is invoked from
         lock_comm.
      
      Finally, thanks to Neil for his great idea and help!

      Pull gfs2 fix from Bob Peterson:
       "This is an emergency patch for 4.11-rc3
      
        The GFS2 developers uncovered a really nasty problem that can lead to
        random corruption and kernel panic, much like the last one. Andreas
        Gruenbacher wrote a simple one-line patch to fix the problem."

      gfs2: Avoid alignment hole in struct lm_lockname · 28ea06c4
      Andreas Gruenbacher authored
      Commit 88ffbf3e switches to using rhashtables for glocks, hashing over
      the entire struct lm_lockname instead of its individual fields.  On some
      architectures, struct lm_lockname contains a hole of uninitialized
      memory due to alignment rules, which now leads to incorrect hash values.
      Get rid of that hole.

      xfs: verify inline directory data forks · 630a04e7
      Darrick J. Wong authored
      When we're reading or writing the data fork of an inline directory,
      check the contents to make sure we're not overflowing buffers or eating
      garbage data.  xfs/348 corrupts an inline symlink into an inline
      directory, triggering a buffer overflow bug.

      v2: add more checks consistent with _dir2_sf_check and make the verifier
      usable from anywhere.
