      rbd: handle locking inside __rbd_client_find() · 1f7ba331
      Alex Elder authored
      There is only caller of __rbd_client_find(), and it somewhat
      clumsily gets the appropriate lock and gets a reference to the
      existing ceph_client structure if it's found.
      
      Instead, have that function handle its own locking, and acquire the
      reference if found while it holds the lock.  Drop the underscores
      from the name because there's no need to signify anything special
      about this function.

          rbd: simplify __rbd_init_snaps_header()
      
      The problem is that a new rbd snapshot needs to go either after an
      existing snapshot entry, or at the *end* of an rbd device's snapshot
      list.  As originally coded, it is placed at the beginning.  This was
      based on the assumption the list would be empty (so it wouldn't
      matter), but in fact if multiple new snapshots are added to an empty
      list in one shot the list will be non-empty after the first one is
      added.

      rbd: rename block_name -> object_prefix · 843a0d08
      Alex Elder authored
      In the on-disk image header structure there is a field "block_name"
      which represents what we now call the "object prefix" for an rbd
      image.  Rename this field "object_prefix" to be consistent with
      modern usage.
      
      This appears to be the only remaining vestige of the use of "block"
      in symbols that represent objects in the rbd code.

      ceph: let path portion of mount "device" be optional · c98f533c
      Alex Elder authored
      A recent change to /sbin/mountall causes any trailing '/' character
      in the "device" (or fs_spec) field in /etc/fstab to be stripped.  As
      a result, an entry for a ceph mount that intends to mount the root
      of the name space ends up with now path portion, and the ceph mount
      option processing code rejects this.
      
      That is, an entry in /etc/fstab like:
          cephserver:port:/ /mnt ceph defaults 0 0
      provides to the ceph code just "cephserver:port:" as the "device,"
      and that gets rejected.
      
      Although this is a bug in /sbin/mountall, we can have the ceph mount
      code support an empty/nonexistent path, interpreting it to mean the
      root of the name space.
      
      RFC 5952 offers recommendations for how to express IPv6 addresses,
      and recommends the usage found in RFC 3986 (which specifies the
      format for URI's) for representing both IPv4 and IPv6 addresses that
      include port numbers.  (See in particular the definition of
      "authority" found in the Appendix of RFC 3986.)
      
      According to those standards, no host specification will ever
      contain a '/' character.  As a result, it is sufficient to scan a
      provided "device" from an /etc/fstab entry for the first '/'
      character, and if it's found, treat that as the beginning of the
      path.  If no '/' character is present, we can treat the entire
      string as the monitor host specification(s), and assume the path
      to be the root of the name space.  We'll still require a ':' to
      separate the host portion from the (possibly empty) path portion.
      
      This means that we can more formally define how ceph will interpret
      the "device" it's provided when processing a mount request:
      
          "device" will look like:
              <server_spec>[,<server_spec>...]:[<path>]
          where
              <server_spec> is <ip>[:<port>]
              <path> is optional, but if present must begin with '/'

      rbd: separate reading header from decoding it · 4156d998
      Alex Elder authored
      Right now rbd_read_header() both reads the header object for an rbd
      image and decodes its contents.  It does this repeatedly if needed,
      in order to ensure a complete and intact header is obtained.
      
      Separate this process into two steps--reading of the raw header
      data (in new function, rbd_dev_v1_header_read()) and separately
      decoding its contents (in rbd_header_from_disk()).  As a result,
      the latter function no longer requires its allocated_snaps argument.

      rbd: return earlier in rbd_header_from_disk() · 28cb775d
      Alex Elder authored
      The only caller of rbd_header_from_disk() is rbd_read_header().
      It passes as allocated_snaps the number of snapshots it will
      have received from the server for the snapshot context that
      rbd_header_from_disk() is to interpret.  The first time through
      it provides 0--mainly to extract the number of snapshots from
      the snapshot context header--so that it can allocate an
      appropriately-sized buffer to receive the entire snapshot
      context from the server in a second request.
      
      rbd_header_from_disk() will not fill in the array of snapshot ids
      unless the number in the snapshot matches the number the caller
      had allocated.
      
      This patch adjusts that logic a little further to be more efficient.
      rbd_read_header() doesn't even examine the snapshot context unless
      the snapshot count (stored in header->total_snaps) matches the
      number of snapshots allocated.  So rbd_header_from_disk() doesn't
      need to allocate or fill in the snapshot context field at all in
      that case.

      rbd: rearrange rbd_header_from_disk() · 6a52325f
      Alex Elder authored
      This just moves code around for the most part.  It was pulled out as
      a separate patch to avoid cluttering up some upcoming patches which
      are more substantive.  The point is basically to group everything
      related to initializing the snapshot context together.
      
      The only functional change is that rbd_header_from_disk() now
      ensures the (in-core) header it is passed is zero-filled.  This
      allows a simpler error handling path in rbd_header_from_disk().

      rbd: make snap_names_len a u64 · 0f1d3f93

      The snap_names_len field of an rbd_image_header structure is defined
      with type size_t.  That field is used as both the source and target
      of 64-bit byte-order swapping operations though, so it's best to

      rbd: simplify __rbd_init_snaps_header() · 35938150
      Alex Elder authored
      The purpose of __rbd_init_snaps_header() is to compare a new
      snapshot context with an rbd device's list of existing snapshots.
      It updates the list by adding any new snapshots or removing any
      that are not present in the new snapshot context.
      
      The code as written is a little confusing, because it traverses both
      the existing snapshot list and the set of snapshots in the snapshot
      context in reverse.  This was done based on an assumption about
      snapshots that is not true--namely that a duplicate snapshot name
      could cause an error in intepreting things if they were not
      processed in ascending order.
      
      These precautions are not necessary, because:
          - all snapshots are uniquely identified by their snapshot id
          - a new snapshot cannot be created if the rbd device has another
            snapshot with the same name
      (It is furthermore not currently possible to rename a snapshot.)
      
      This patch re-implements __rbd_init_snaps_header() so it passes
      through both the existing snapshot list and the entries in the
      snapshot context in forward order.  It still does the same thing
      as before, but I find the logic considerably easier to understand.
      
      By going forward through the names in the snapshot context, there
      is no longer a need for the rbd_prev_snap_name() helper function.

      vfs: dcache: fix deadlock in tree traversal · 8110e16d
      Miklos Szeredi authored
      IBM reported a deadlock in select_parent().  This was found to be caused
      by taking rename_lock when already locked when restarting the tree
      traversal.
      
      There are two cases when the traversal needs to be restarted:
      
       1) concurrent d_move(); this can only happen when not already locked,
          since taking rename_lock protects against concurrent d_move().
      
       2) racing with final d_put() on child just at the moment of ascending
          to parent; rename_lock doesn't protect against this rare race, so it
          can happen when already locked.
      
      Because of case 2, we need to be able to handle restarting the traversal
      when rename_lock is already held.  This patch fixes all three callers of
      try_to_ascend().
      
      IBM reported that the deadlock is gone with this patch.
      
      [ I rewrote the patch to be smaller and just do the "goto again" if the
        lock was already held, but credit goes to Miklos for the real work.

      bnx2: Clean up remaining iounmap · 64f605c7
      Neil Horman authored
      commit c0357e97 modified bnx2 to switch from
      using ioremap/iounmap to pci_iomap/pci_iounmap.  They missed a spot in the error
      path of bnx2_init_one though.  This patch just cleans that up.

      Pull EDAC fixes from Mauro Carvalho Chehab:
       "Three edac fixes at the memory enumeration logic:
              - i3200_edac: Fixes a regression at the memory rank size, when the
                      memorias are dual-rank;
              - i5000_edac: Fix a longstanding bug when calculating the memory
                      size: before Kernel 3.6, the memory size were right only
                      with one specific configuration;
              - sb_edac: Fixes a bug since the initial release of the driver:
                      with 16GB DIMMs, there's an overflow at the memory size,
                      causing the number of pages per dimm (an unsigned value)
                      to have the highest bit equal to 1, effectively mangling
                      the memory size.
      
        The third bug can potentially affect the error decoding logic as well."
