Report access, modification, status update and creation time in Unix format. Report number of links pointing to a given entry. If the entry is a symbolic link, report the path of its target. If the filesystem supports native/transparent compression, report compressed files with dedicated flag (DIRENT_COMPRESSED 0x04).

v3: - fixed attribute walk callback: checking against TSK_FS_BLOCK_FLAG_RAW flag would exclude compressed data blocks which are still important. Yet we want to exclude sparse blocks (TSK_FS_BLOCK_FLAG_SPARSE) as they are not stored on the disk.

Patch ready for merging. v4: - check return code of tsk_fs_attr_walk - pass TSK_FS_FILE_WALK_FLAG_NOSPARSE as additional flag to tsk_fs_attr_walk After discussing with TSK authors the behaviour is clear. [1] In case of COMPRESSED blocks, the callback will be called for all the attributes no matter whether they are on disk or not (sparse). In such cases, the block address will be 0. [2] So

This series is ready for review but requires the previous one to be merged first: https://www.redhat.com/archives/libguestfs/2016-September/msg00101.html The find_block API allows the User to search all the filesystem entries referring to a given data block and returns a tsk_dirent structure for each of them. Use case examples: - Check whether a block containing a deleted file has been re-used
