2019-07-25cleanup: remove some redundant header inclusionsDavid Oberhollenzer
The utility programs pretty much all have the same structure of including one central header per C file that includes all required library headers, so we can simply include config.h which we need for large file support from there and remove it from the C files.

2019-07-24Enable largefile supportMatt Turner
Requires that config.h be included before other headers, since the macro _FILE_OFFSET_BITS changes the definitions of things like 'struct stat'. I chose to simply include it at the top of every C file and at immediately after the double-inclusion guards of every header.

2019-07-01Fix null-pointer dereference in restore_unpackDavid Oberhollenzer
Use a seperate variable to iterate over directory children and don't modify n. Otherwise, the chown/chmod code below derefernces a null pointer when trying to access n->name, n->uid and n->gid. Bug found using scan-build. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-05-05rdsquashfs: reorder unpack flags, add flag to produce listingDavid Oberhollenzer
The listing command has been used successfully to do the following: - generate a prestine file system using gensquashfs - repeate multiple times: - generate a listing from the file system - unpack only the regular files from the file system - generate a new file system from the listing - run `diff` on the old and new filesystem and admire that they are identical - replace the old file system with the new one, since they are identical Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-05-04Rename tools to not collide with squashfs-toolsDavid Oberhollenzer
This commit changes the names of the tools to gensquashfs and rdsquashfs so they don't collide with the names used by the squashfs-tools package and the two can be installed side by side. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-05-03unsquashfs: add flags to filter what file types to unpackDavid Oberhollenzer
This allows the user to skip stuff like device special files (which non-root can't create anyway) or to not create symlinks/fifos etc... Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
