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>
