2019-08-23Some simple search/replace cases for allocationDavid Oberhollenzer
This commit exchanges some malloc(x + y * z) patterns that can be found with a simple git grep and are obvious for the new wrappers. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-01Add xattr reader implementation to recover xattrs from squashfsDavid Oberhollenzer

2019-08-01Fix xattr writer size accountingDavid Oberhollenzer

2019-08-01Fix super block flags: clear "no xattr" flag when writing xattrsDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-01Fix xattr OOL positionDavid Oberhollenzer
We need to get the position _before_ writing the header, otherwise the reader has no way to know the length of the value. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-30Add propper copyright headers to all source filesDavid Oberhollenzer

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.

2019-07-21Add support for storing xattr values out-of-lineDavid Oberhollenzer

2019-07-21Cleanup xattr handlingDavid Oberhollenzer
- Store them in a struct instead of a hacky uint64_t with magic shifts - Split up key/value pair write function to write_key and write_value - Move the size accounting into those functions respectively Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-16cleanup: move error handling into write_retryDavid Oberhollenzer
If write_retry fails to write everything, it is *always* an error. This commit renames write_retry to write_data and moves error handling into the function, making a lot of error handling code redundant. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-10Add a way to keep meta data blocks in memoryDavid Oberhollenzer
Instead of writing meta data blocks directly to disk, the writer can now alternatively keep the blocks in memory until explicitly told to write to disk. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
