ext4_search_dir() and ext4_generic_delete_entry() can be called both for standard director blocks and for inline directories stored inside inode or inline xattr space. For the second case we didn't call ext4_check_dir_entry() with proper constraints that could result in accepting corrupted directory entry as well as false positive filesystem errors like: EXT4-fs error (device dm-0): ext4_search_dir:1395: inode #28320400: block 113246792: comm dockerd: bad entry in directory: directory entry too close to block end - offset=0, inode=28320403, rec_len=32, name_len=8, size=4096 Fix the arguments passed to ext4_check_dir_entry(). Fixes: 109ba779 ("ext4: check for directory entries too close to block end") CC: stable@vger.kernel.org Signed-off-by:
