      "title": "ocfs2: reject dinodes with non-canonical i_mode type",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: reject dinodes with non-canonical i_mode type\n\nPatch series \"ocfs2: harden inode validators against forged metadata\", v2.\n\nThis series adds three structural checks to OCFS2 dinode validation so\nmalformed on-disk fields are rejected before ocfs2_populate_inode() copies\nthem into the in-core inode.\n\nThe checks cover:\n\n  - i_mode values whose type bits do not name a canonical POSIX file\n    type;\n  - non-device dinodes whose id1.dev1.i_rdev field is non-zero; and\n  - non-inline dinodes that claim non-zero i_size while i_clusters is\n    zero, covering directories unconditionally and regular files on\n    non-sparse volumes.\n\nThe normal read path reports these through ocfs2_error(), matching the\nexisting suballoc-slot, inline-data, chain-list, and refcount checks.  The\nonline filecheck path uses the same structural predicates but keeps its\nown reporting contract, returning OCFS2_FILECHECK_ERR_INVALIDINO instead\nof calling ocfs2_error().\n\n\nThis patch (of 3):\n\nocfs2_validate_inode_block() currently accepts any non-zero i_mode value. \nocfs2_populate_inode() then copies that mode verbatim into inode->i_mode\nand dispatches on i_mode & S_IFMT to the file/dir/symlink/special_file\niops; an unrecognised type falls through to ocfs2_special_file_iops and\ninit_special_inode().\n\nReject dinodes whose type bits do not name one of the seven canonical\nPOSIX file types.  Use fs_umode_to_ftype(), the same generic file-type\nconversion helper OCFS2 already uses for directory entries, so the\naccepted inode type set matches the kernel file-type vocabulary instead of\nopen-coding a local switch.\n\nApply the same structural check to the online filecheck read path. \nfilecheck keeps its own error namespace, so it reports malformed i_mode\nthrough the filecheck logger and OCFS2_FILECHECK_ERR_INVALIDINO instead of\ncalling ocfs2_error(), but it must not allow a malformed dinode to proceed\ninto ocfs2_populate_inode().",
