- The libcommon print verion function requires the PACKAGE_NAME and PACKAGE_VERSION defines. Those are added manually to the msvc stub of config.h. - Also, libcommon cannot directly include getopt.h - libfstree needs to change the return type for getline Signed-off-by: David Oberhollenzer

Simplify hard link handling

2019-12-23T19:19:46+00:00

- For now, enforce that hard links don't point to a directories. - Instead of doing the swaping trickery, just reorder the flat list and hand out new inode numbers. Signed-off-by: David Oberhollenzer

Minor cleanup in inode allocation

2019-12-23T14:37:00+00:00

- Remove unnecessary counter argument, we already have the total count. - Remove the return status, there is no failure branch. Signed-off-by: David Oberhollenzer

Bring back the flat list of inodes in libfstree

It makes further processing simpler and doesn't leak the abstraction into upper layers. Signed-off-by: David Oberhollenzer

Add hard link support to gensquashfs and tar2sqfs

2019-12-22T21:07:44+00:00

In libtar, set a special flag if the header is actually a hard link. In tar2sqfs, create a hard link node and skip the rest for hard links. Also refues to set the root attributes from a hard link, it may refere to a node that we have missed earlier, there is nothing else that we can do here. In fstree_from_file, add a "link" command for adding hard links. Signed-off-by: David Oberhollenzer

Add basic support for handling and serializing hard links

2019-12-22T21:07:44+00:00

In libfstree, add a function to add a hard link to the fstree. The hard links stores the target in the data.target field, canonicalizes the target and sets a sentinel mode. A second function is used to resolve link, i.e. replacing it with a direct pointer, setting another sentinel mode and increasing the targets link count. The post process function tries to resolve unresolved hard links and only allocates inode numbers for nodes that aren't hard links. If the target node of a hard link does not have an inode number yet, the two need to be swapped, since this is also the order in which they are serialized. The serialization function in libcommon simply has to skip hard link nodes and when writing directory entries, use the inode num/ref of the target node. Signed-off-by: David Oberhollenzer

Add an explicit link count to the fstree nodes

Gets initialized to 2 for directories, 1 for all other types. The count of the parent node is automatically incremented. Signed-off-by: David Oberhollenzer
