2019-09-08	Replace direct file I/O with abstraction layer	David Oberhollenzer
	This should make it easier to use libsquashfs with custom setups that embedd a squashfs image inside something else. Also, it should make it easier to port to non unix-like platforms. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-05	Cleanup naming scheme of compressor	David Oberhollenzer
	Add sqfs_* prefix to compressor, move implementation prefix up front. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-05	Cleanup: add sqfs_* prefix to id table	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-05	Cleanup: unify sqfs/SQFS name prefix for xattr reader	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-04	Store number of file blocks in generic inode struct	David Oberhollenzer
	This simplifies things a little bit. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-04	Split fstree inode serialization, move independend part to libsquashfs.so	David Oberhollenzer
	This commit adds a function to libsquashfs.so for writing generic inodes to a meta writer and another function to libsqfshelper.a that turns a tree node to an inode. That way, the tree serialization code can be expressed in terms of those functions and a bulk of the independend code can be moved over to libsquashfs.so Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-04	Add fstree independend directory writer to libsquashfs.so	David Oberhollenzer
	This commit adds a directory writer to libsquashfs that wrapps a meta data writer and provides a higher-level interface for writing directory entries. Under the hood it enforces the rules that squashfs insists upon. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-02	Move fstree independend parts of xattr_reader to libsquashfs.so	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-01	Move command line processing stuff out of compressor code	David Oberhollenzer
	This commit moves stuff like printing help text, command line option processing and enumerating available processors on stdout out of the generic compressor code. The option string is replaced with a structure that directly exposese the tweakable parameters for all compressors. A function for parsing the command line arguments into this structure is added in sqfshelper. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-01	API cleanup: Shuffle declarations around	David Oberhollenzer
	Move declarations for stuff that is defined in libsquashfs.so into the public headers and declarations for stuff that isn't, out of there. Also move the meta reader/writer helper functions to their respective headers. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-01	Break up squashfs.h into topic related headers	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-01	Install libsquashfs.so headers on the system in "sqfs" subdirectory	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-23	Do bounds checking in metadata reader	David 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. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-05	cleanup: unify all the code that reads squashfs images	David 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>
2019-08-01	Add option to restore xattrs to deserialize_fstree	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-30	Add propper copyright headers to all source files	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-28	Add some nice statistics output to tar2sqfs and gensquashfs	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-25	Add generic read_table function similar to write_table	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-25	Cleanup sqfs_write_table	David 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>
2019-07-24	Enable largefile support	Matt 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.

2019-07-21	Implement generating an inode table for NFS export	David Oberhollenzer

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