2019-09-27Cleanup: replace fixed with data types with typedefsDavid Oberhollenzer
This is a fully automated search and replace, i.e. I ran this: git grep -l uint8_t | xargs sed -i 's/uint8_t/sqfs_u8/g' git grep -l uint16_t | xargs sed -i 's/uint16_t/sqfs_u16/g' git grep -l uint32_t | xargs sed -i 's/uint32_t/sqfs_u32/g' git grep -l uint64_t | xargs sed -i 's/uint64_t/sqfs_u64/g' git grep -l int8_t | xargs sed -i 's/int8_t/sqfs_s8/g' git grep -l int16_t | xargs sed -i 's/int16_t/sqfs_s16/g' git grep -l int32_t | xargs sed -i 's/int32_t/sqfs_s32/g' git grep -l int64_t | xargs sed -i 's/int64_t/sqfs_s64/g' and than added the appropriate definitions to sqfs/predef.h The whole point being better compatibillity with platforms that may not have an stdint.h with the propper definitions.

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.

2019-07-21Cleanup 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>
2019-07-21Keep track of xattr key & value references AFTER deduplicationDavid Oberhollenzer
This commit adds a reference count functionality to the string table implementation and uses this functionality in the fstree code to count how often each key and value is referenced by the deduplicated Xattr blocks. This is needed to support deduplication through out-of-band storage of xattrs. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-01Fix use of uninitialized xattr structureDavid Oberhollenzer
The refactor of the xattr table grow code merged all allocation code paths into realloc(), including the initial allocation. This means that the xattr structure is used uninitialized. This commit makes sure the reallocated structure is alwayes cleared. Bug found using scan-build. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-06-23Split up fstree_add_xattrDavid Oberhollenzer
This IMO makes it somewhat easier to read and understand what's going on. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
