[PATCH v7 0/2] ocfs2: validate xattr entry bounds

Hi,

This series validates OCFS2 xattr entry name/value bounds when xattr
metadata is read and validated, before getxattr() or listxattr() can
walk out-of-range entry arrays or offsets from corrupted metadata.

Patch 1 validates inline xattrs from ocfs2_validate_inode_block().
Patch 2 validates non-indexed xattr blocks from ocfs2_validate_xattr_block()
and indexed xattr buckets after bucket ECC validation.

  ocfs2: validate inline xattrs during inode block validation
  ocfs2: validate external xattr entries when reading metadata
