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). Matteo Cafasso (2): filesystem_walk: more information into tsk_dirent

v3: - coding style fixes - comment entry_is_dot logic Matteo Cafasso (6): filesystem_walk: fixed root inode listing daemon: refactor tsk code lib: rename tsk internal function New API: internal_find_inode New API: find_inode find_inode: added API tests daemon/tsk.c | 157 ++++++++++++++++++++++++++++++------------- generator/actions.ml | 21 ++++++

v4: - refactor entry_is_dot My apologies for the duplicated submission but I did not read the next e-mail. The tsk_fs_dir_walk API will list all the entries including '.' and '..' in a similar manner as for 'ls -a'. This means our callback will be called for the following entries: . <-- the Root entry etc/. etc/.. <-- again the Root entry etc/systemd/.

v5: - small doc fix: filesystem_walk claimed '.' and '..' entries were not reported but Root is now reported as '.' - bump to 1.35.6 Matteo Cafasso (6): filesystem_walk: fixed root inode listing daemon: refactor tsk code lib: rename tsk internal function New API: internal_find_inode New API: find_inode find_inode: added API tests daemon/tsk.c

This series should be ready for merge v6: - rebase on master - changes according to last comments Matteo Cafasso (6): filesystem_walk: fixed root inode listing daemon: refactor tsk code lib: rename tsk internal function New API: internal_find_inode New API: find_inode find_inode: added API tests daemon/tsk.c | 155 ++++++++++++++++++++++++++++++-------------

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
