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.

2019-07-25Fix checks of super block block sizeDavid Oberhollenzer
Make sure range is checked when reading a block and that the check is made correctly. Also make the block log check a little more strict. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-25Replace reads in squashfs with positional readsDavid Oberhollenzer
In most cases, we know exactely where the data that we want to read is on disk, so instead of using read() on the squashfs (or lseek + read), the code can in many places be cleaned up to use the pread wrapper read_data_at instead.

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.

2019-07-16cleanup: move error handling into read_retryDavid Oberhollenzer
If read_retry fails to read the expected amount of data (EOF or otherwise), it is almost always an error. This commit renames read_retry to read_data and moves error handling into the function, making a lot of error handling code redundant.
