2019-08-23Do bounds checking in metadata readerDavid Oberhollenzer
In all cases where metadata blocks are read, we can roughly (in some cases even preciesly) say in what range those metadata blocks will be, so it makes sense to throw an error if an attempt is made to wander outside this range. Furthermore, when reading from an uncompressed block, it is more reasonable to check against the actual block bounds than to padd it with 0 bytes.

2019-08-05cleanup: unify all the code that reads squashfs imagesDavid Oberhollenzer
This commit creates a new data structure called 'sqfs_reader_t' that takes care of all the repetetive tasks like opening the file, reading the super block, creating the compressor, deserializing an fstree and creating a data reader. This in turn makes it possible to remove all the duplicate code from rdsquashfs and sqfs2tar. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-07-25Cleanup sqfs_write_tableDavid Oberhollenzer
This commit attempts to make the generic table writer more readable. A few changes are made, including heap allocation of the block list. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
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.

2019-06-10Rename table.h to highlevel.hDavid Oberhollenzer
The idea is to move various higher level helper functions there. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
