      ocfs2: Add incompatible flag for extended attribute · 8154da3d
      Tiger Yang authored
      This patch adds the s_incompat flag for extended attribute support. This
      helps us ensure that older versions of Ocfs2 or ocfs2-tools will not be able
      to mount a volume with xattr support.

      ocfs2: Enable xattr set in index btree · 01225596
      Tao Ma authored
      Where the previous patches added the ability of list/get xattr in buckets
      for ocfs2, this patch enables ocfs2 to store large numbers of EAs.
      
      The original design doc is written by Mark Fasheh, and it can be found in
      http://oss.oracle.com/osswiki/OCFS2/DesignDocs/IndexedEATrees. I only had to
      make small modifications to it.
      
      First, because the bucket size is 4K, a new field named xh_free_start is added
      in ocfs2_xattr_header to indicate the next valid name/value offset in a bucket.
      It is used when we store new EA name/value. With this field, we can find the
      place more quickly and what's more, we don't need to sort the name/value every
      time to let the last entry indicate the next unused space. This makes the
      insert operation more efficient for blocksizes smaller than 4k.
      
      Because of the new xh_free_start, another field named as xh_name_value_len is
      also added in ocfs2_xattr_header. It records the total length of all the
      name/values in the bucket. We need this so that we can check it and defragment
      the bucket if there is not enough contiguous free space.
      
      An xattr insertion looks like this:
      1. xattr_index_block_find: find the right bucket by the name_hash, say bucketA.
      2. check whether there is enough space in bucketA. If yes, insert it directly
         and modify xh_free_start and xh_name_value_len accordingly. If not, check
         xh_name_value_len to see whether we can store this by defragment the bucket.
         If yes, defragment it and go on insertion.
      3. If defragement doesn't work, check whether there is new empty bucket in
         the clusters within this extent record. If yes, init the new bucket and move
         all the buckets after bucketA one by one to the next bucket. Move half of the
         entries in bucketA to the next bucket and go on insertion.
      4. If there is no new bucket, grow the extent tree.
      
      As for xattr deletion, we will delete an xattr bucket when all it's xattrs
      are removed and move all the buckets after it to the previous one. When all
      the xattr buckets in an extend record are freed, free this extend records
      from ocfs2_xattr_tree.

      ocfs2: Optionally limit extent size in ocfs2_insert_extent() · ca12b7c4
      Tao Ma authored
      In xattr bucket, we want to limit the maximum size of a btree leaf,
      otherwise we'll lose the benefits of hashing because we'll have to search
      large leaves.
      
      So add a new field in ocfs2_extent_tree which indicates the maximum leaf cluster
      size we want so that we can prevent ocfs2_insert_extent() from merging the leaf
      record even if it is contiguous with an adjacent record.
      
      Other btree types are not affected by this change.

      ocfs2: Add xattr lookup code xattr btrees · 589dc260
      Tao Ma authored
      Add code to lookup a given extended attribute in the xattr btree. Lookup
      follows this general scheme:
      
      1. Use ocfs2_xattr_get_rec to find the xattr extent record
      
      2. Find the xattr bucket within the extent which may contain this xattr
      
      3. Iterate the bucket to find the xattr. In ocfs2_xattr_block_get(), we need
         to recalcuate the block offset and name offset for the right position of
         name/value.

      ocfs2: Add xattr bucket iteration for large numbers of EAs · 0c044f0b
      Tao Ma authored
      Ocfs2 breaks up xattr index tree leaves into 4k regions, called buckets.
      Attributes are stored within a given bucket, depending on hash value.
      
      After a discussion with Mark, we decided that the per-bucket index
      (xe_entry[]) would only exist in the 1st block of a bucket. Likewise,
      name/value pairs will not straddle more than one block. This allows the
      majority of operations to work directly on the buffer heads in a leaf block.
      
      This patch adds code to iterate the buckets in an EA. A new abstration of
      ocfs2_xattr_bucket is added. It records the bhs in this bucket and
      ocfs2_xattr_header. This keeps the code neat, improving readibility.

      This patch implements storing extended attributes both in inode or a single
      external block. We only store EA's in-inode when blocksize > 512 or that
      inode block has free space for it. When an EA's value is larger than 80
      bytes, we will store the value via b-tree outside inode or block.

      ocfs2: Add extent tree operation for xattr value btrees · f56654c4
      Tao Ma authored
      Add some thin wrappers around ocfs2_insert_extent() for each of the 3
      different btree types, ocfs2_inode_insert_extent(),
      ocfs2_xattr_value_insert_extent() and ocfs2_xattr_tree_insert_extent(). The
      last is for the xattr index btree, which will be used in a followup patch.
      
      All the old callers in file.c etc will call ocfs2_dinode_insert_extent(),
      while the other two handle the xattr issue. And the init of extent tree are
      handled by these functions.
      
      When storing xattr value which is too large, we will allocate some clusters
      for it and here ocfs2_extent_list and ocfs2_extent_rec will also be used. In
      order to re-use the b-tree operation code, a new parameter named "private"
      is added into ocfs2_extent_tree and it is used to indicate the root of
      ocfs2_exent_list. The reason is that we can't deduce the root from the
      buffer_head now. It may be in an inode, an ocfs2_xattr_block or even worse,
      in any place in an ocfs2_xattr_bucket.

      ocfs2: Add the basic xattr disk layout in ocfs2_fs.h · 5a7bc8eb
      Tao Ma authored
      Ocfs2 uses a very flexible structure for storing extended attributes on
      disk. Small amount of attributes are stored directly in the inode block - up
      to 256 bytes worth. If that fills up, attributes are also stored in an
      external block, linked to from the inode block. That block can in turn
      expand to a btree, capable of storing large numbers of attributes.
      
      Individual attribute values are stored inline if they're small enough
      (currently about 80 bytes, this can be changed though), and otherwise are
      expanded to a btree. The theoretical limit to the size of an individual
      attribute is about the same as an inode, though the kernel's upper bound on
      the size of an attributes data is far smaller.

      ocfs2: Abstract ocfs2_extent_tree in b-tree operations. · e7d4cb6b
      Tao Ma authored
      In the old extent tree operation, we take the hypothesis that we
      are using the ocfs2_extent_list in ocfs2_dinode as the tree root.
      As xattr will also use ocfs2_extent_list to store large value
      for a xattr entry, we refactor the tree operation so that xattr
      can use it directly.
      
      The refactoring includes 4 steps:
      1. Abstract set/get of last_eb_blk and update_clusters since they may
         be stored in different location for dinode and xattr.
      2. Add a new structure named ocfs2_extent_tree to indicate the
         extent tree the operation will work on.
      3. Remove all the use of fe_bh and di, use root_bh and root_el in
         extent tree instead. So now all the fe_bh is replaced with
         et->root_bh, el with root_el accordingly.
      4. Make ocfs2_lock_allocators generic. Now it is limited to be only used
         in file extend allocation. But the whole function is useful when we want
         to store large EAs.
      
      Note: This patch doesn't touch ocfs2_commit_truncate() since it is not used
      for anything other than truncate inode data btrees.

      ocfs2: throttle back local alloc when low on disk space · 9c7af40b
      Mark Fasheh authored
      Ocfs2's local allocator disables itself for the duration of a mount point
      when it has trouble allocating a large enough area from the primary bitmap.
      That can cause performance problems, especially for disks which were only
      temporarily full or fragmented. This patch allows for the allocator to
      shrink it's window first, before being disabled. Later, it can also be
      re-enabled so that any performance drop is minimized.
      
      To do this, we allow the value of osb->local_alloc_bits to be shrunk when
      needed. The default value is recorded in a mostly read-only variable so that
      we can re-initialize when required.
      
      Locking had to be updated so that we could protect changes to
      local_alloc_bits. Mostly this involves protecting various local alloc values
      with the osb spinlock. A new state is also added, OCFS2_LA_THROTTLED, which
      is used when the local allocator is has shrunk, but is not disabled. If the
      available space dips below 1 megabyte, the local alloc file is disabled. In
      either case, local alloc is re-enabled 30 seconds after the event, or when
      an appropriate amount of bits is seen in the primary bitmap.

      ocfs2: POSIX file locks support · 53da4939
      Mark Fasheh authored
      This is actually pretty easy since fs/dlm already handles the bulk of the
      work. The Ocfs2 userspace cluster stack module already uses fs/dlm as the
      underlying lock manager, so I only had to add the right calls.
      
      Cluster-aware POSIX locks ("plocks") can be turned off by the same means at
      UNIX locks - mount with 'noflocks', or create a local-only Ocfs2 volume.
      Internally, the file system uses two sets of file_operations, depending on
      whether cluster aware plocks is required. This turns out to be easier than
      implementing local-only versions of ->lock.

      The multiple drivers share the minor space occupied by a particular major
      number, the actual index within the device name's space is indicated by
      the tty_driver->name_base + uart_port->line
      
      Another usable formula is (uart_driver->minor - MINOR_BASE) + port->line

      Many tty drivers contain 'can't happen' checks against NULL pointers passed
      in by the tty layer. These have never been possible to occur. Even more
      importantly if they ever do occur we want to know as it would be a serious
      bug.
