2019-09-05Fix API visibility for libsquashfs.soDavid Oberhollenzer
This commit adds a "predef.h" header to libsquashfs that exposes two macros, SQFS_API and SQFS_INTERNAL that are used to explicilty set the visibiliy of stuff that ends up in libsquashfs to default or hidden. For compatibillity with Windows which may at some point eventually be considered, the SQFS_API define is set to dllexport IF the cpp symbol SQFS_BUILDING_DLL is defined and set to import otherwise.

2019-09-01API cleanup: Shuffle declarations aroundDavid 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>

2019-08-23Check against format limits in meta_reader_read_dir_headerDavid Oberhollenzer
The SquashFS kernel implementation insists that a directory header is followed by no more than an upper bound of entries, way less than what the filed itself actually supports. This commit makes sure that the meta_reader_read_dir_header function also enforces that same limit. 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.

2019-07-07Actually encode/decode directory inode difference as signedDavid Oberhollenzer
The directory listing stores a signed difference of the inode number. Actually treating it as signed saves emitting extra headers if hard links or file deduplication are finally implemented. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
