2019-06-22Cleanup: split fstree sort into 2 fstree independend functionsDavid Oberhollenzer
Make tree node list sort and recursive variant available and independend of the fstree_t. This is considered cleaner, since the fstree_t actually isn't needed for any of this and we can just call the recusvie sort on the root instead, and we can use the sort implementation directly for things like the upcoming unit test. Also this commit splits up the merge/sort implementation into a seperate split and merge functions to make the code somewhat more readable.

2019-06-22simplify SELinux labelingDavid Oberhollenzer
This commit moves the SELinux label code after the tree is sorted and the inode table is generated. Sorting helps to make sure that the tree will always be traversed in a defined, deterministic order and likewise the creation of xattrs happens in a defined, deterministic order. Second, we can now use the inode table instead of having to implement a recursive tree traversal yet again. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-06-10Generate a flat inode table from the fstree ahead of timeDavid Oberhollenzer
Instead of allocating inode numbers as we go, generate and populat an inode table from the fstree ahead of time. This makes processing nodes a little bit simpler and we will need that table anyway for NFS export support later on. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-05-06Implement reading and writing of compressor optionsDavid Oberhollenzer
- gensquashfs simply asks the backend compressor to write its options to the file and does accounting - rdsquasfs simply asks the backend compressor to transparentyl snort the options from the file - not implemented in any compressor backend yet Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
