      ext4: fix growing of tiny filesystems · 2c869b26
      Jan Kara authored
      The estimate of necessary transaction credits in ext4_flex_group_add()
      is too pessimistic. It reserves credit for sb, resize inode, and resize
      inode dindirect block for each group added in a flex group although they
      are always the same block and thus it is enough to account them only
      once. Also the number of modified GDT block is overestimated since we
      fit EXT4_DESC_PER_BLOCK(sb) descriptors in one block.
      
      Make the estimation more precise. That reduces number of requested
      credits enough that we can grow 20 MB filesystem (which has 1 MB
      journal, 79 reserved GDT blocks, and flex group size 16 by default).

      ext4: move check under lock scope to close a race. · 280227a7
      Davide Italiano authored
      fallocate() checks that the file is extent-based and returns
      EOPNOTSUPP in case is not. Other tasks can convert from and to
      indirect and extent so it's safe to check only after grabbing
      the inode mutex.

      ext4: fix data corruption caused by unwritten and delayed extents · d2dc317d
      Lukas Czerner authored
      Currently it is possible to lose whole file system block worth of data
      when we hit the specific interaction with unwritten and delayed extents
      in status extent tree.
      
      The problem is that when we insert delayed extent into extent status
      tree the only way to get rid of it is when we write out delayed buffer.
      However there is a limitation in the extent status tree implementation
      so that when inserting unwritten extent should there be even a single
      delayed block the whole unwritten extent would be marked as delayed.
      
      At this point, there is no way to get rid of the delayed extents,
      because there are no delayed buffers to write out. So when a we write
      into said unwritten extent we will convert it to written, but it still
      remains delayed.
      
      When we try to write into that block later ext4_da_map_blocks() will set
      the buffer new and delayed and map it to invalid block which causes
      the rest of the block to be zeroed loosing already written data.
      
      For now we can fix this by simply not allowing to set delayed status on
      written extent in the extent status tree. Also add WARN_ON() to make
      sure that we notice if this happens in the future.
      
      This problem can be easily reproduced by running the following xfs_io.
      
      xfs_io -f -c "pwrite -S 0xaa 4096 2048" \
                -c "falloc 0 131072" \
                -c "pwrite -S 0xbb 65536 2048" \
                -c "fsync" /mnt/test/fff
      
      echo 3 > /proc/sys/vm/drop_caches
      xfs_io -c "pwrite -S 0xdd 67584 2048" /mnt/test/fff
      
      This can be theoretically also reproduced by at random by running fsx,
      but it's not very reliable, though on machines with bigger page size
      (like ppc) this can be seen more often (especially xfstest generic/127)

      ext4 crypto: do not select from EXT4_FS_ENCRYPTION · fb63e548
      Herbert Xu authored
      This patch adds a tristate EXT4_ENCRYPTION to do the selections
      for EXT4_FS_ENCRYPTION because selecting from a bool causes all
      the selected options to be built-in, even if EXT4 itself is a
      module.
